Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims benefit of priority based on U.S.
Provisional Patent Application No. 61/027,604 filed on Feb. 11,
2008. The contents of this application are incorporated herein by
reference in their entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a slot machine offering a
special payout and a method for controlling the same.
[0004] 2. Discussion of the Background
[0005] In conventional slot machines, when a player inserts game
media such as medals, coins or bills into an insertion slot of the
slot machine and presses a spin button, then a plurality of symbols
are scroll-displayed to a display portion provided on the front
surface of a casing and, thereafter, the respective symbols are
automatically stopped, as disclosed in U.S. Pat. Nos. 6,960,133,
6,012,983 and 6,093,102. In this case, when scroll-display of
respective symbols starts by an input from the spin button, symbols
are selected using random numbers, and the selected symbols are
stop-displayed to the display portion. Then, when a combination of
the stop-displayed symbols along a winning line is a predetermined
winning combination (prize), a payout is conducted.
[0006] Further, among conventional slot machines, there are some
slot machines which conduct two types of payouts which are a payout
determined according to the combinations of symbols rearranged
along winning lines and a payout determined according to the number
of displayed scatter symbols, as disclosed in U.S. Pat. No.
6,604,999 and U.S. 2002-0065124-A1. In such a slot machine which
conducts payouts based on such scatter symbols, there is no
relationship between payouts and positions at which the scatter
symbols are displayed.
[0007] Generally, in the above-mentioned conventional slot
machines, in the case where plural types of predetermined prizes
are established, game media in amount corresponding to the total
sum of amounts of respective payouts determined for the respective
prizes are paid out to the player. That is, although plural types
of prizes are established, an amount of a payout to be offered to
the player is only an amount obtained by simple addition of amounts
of payouts determined based on the respective prizes.
[0008] Thus, although plural types of prizes are established, the
amount of game media to be offered to the player is only the total
sum of the amounts of game media to be offered when each prize is
established independently, so that lack of significant increase in
amounts of payouts causes a problem that the player possibly loses
a sense of expectation for the payouts.
[0009] Moreover, in the conventional slot machines, symbols to be
displayed (for example, a symbol "watermelon") are used as a
component factor of a predetermined prize (for example,
rearrangement of three "watermelons"), and are not symbols that
increase an amount of a payout determined based on a prize upon
establishment of the prize (for example, symbol that increases an
amount of a payout based on the prize of three "watermelons"
3-fold). Therefore, the player has interests only in symbols that
can be a component factor of the predetermined prize, resulting in
a tendency of the player to get bored.
[0010] In light of the aforementioned problems, the present
invention has been devised, and an object of the present invention
is to provide a slot machine and a game control method which enable
preventing the player from losing a sense of expectation for
payouts and avoid a tendency of the player to get bored.
[0011] The contents of U.S. Pat. No. 6,960,133, U.S. Pat. No.
6,012,983, U.S. Pat. No. 6,093,102, U.S. Pat. No. 6,604,999 and
U.S. 2002-0065124-A1 are incorporated herein by reference in their
entirety.
SUMMARY OF THE INVENTION
[0012] The present invention provides a slot machine having the
following configuration.
[0013] That is, the slot machine comprises a display, a
multiplying-factor-symbol display device and a controller.
[0014] The display is capable of rearranging a plurality of normal
symbols. The multiplying-factor-symbol display device is capable of
varying and displaying a plurality of multiplying-factor symbols
each having a different number from one another displayed thereon.
The controller is programmed to execute processing of:
[0015] (A) rearranging the plurality of the normal symbols to the
display;
[0016] (B-1) determining a normal payout amount, based on the
numbers of the normal symbols of respective types rearranged in the
processing (A);
[0017] (C) stop-displaying a single multiplying-factor symbol by
the multiplying-factor-symbol display device, after varying and
displaying the multiplying-factor symbols; and
[0018] (D-1) paying out game media in amount obtained by
multiplying the normal payout amount determined in the processing
(B-1) by the number displayed on the multiplying-factor symbol
stop-displayed in the processing (C).
[0019] According to the aforementioned slot machine, a single
multiplying-factor symbol is stop-displayed by the
multiplying-factor-symbol display device, after the
multiplying-factor symbols are varied and displayed. Each of the
multiplying-factor symbols has a number displayed thereon. Further,
game media in amount obtained by multiplying the normal payout by
the number displayed on the multiplying-factor symbol are paid
out.
[0020] As described above, according to the aforementioned slot
machine, a player can acquire several times larger amount of game
media, based on the multiplying-factor symbol stop-displayed by the
multiplying-factor-symbol display device, resulting in enhancement
of a sense of expectancy of the player for payouts. Therefore, it
is possible to prevent the player from losing a sense of expectancy
for payouts.
[0021] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire is stop-displayed, it is possible to lead the player to
have interests and concern for the number displayed on the
multiplying-factor symbol to be stop-displayed. Furthermore, since
the player plays games with a great sense of expectancy for
stop-display of a multiplying-factor symbol having a larger number
displayed thereon, it is possible to prevent the player from
getting bored with games soon.
[0022] Further, the slot machine of the present invention
preferably has the following configuration.
[0023] That is, the multiplying-factor symbols are colored or have
a colored background. Further, the processing (D-1) is processing
for paying out, when a multiplying-factor symbol colored a
predetermined color or having a background colored the
predetermined color is stop-displayed in the processing (C), game
media in amount obtained by multiplying the normal payout amount
determined in the processing (B-1) by the number displayed on the
multiplying-factor symbol.
[0024] Thus, according to the aforementioned slot machine, the
player can acquire a several times larger amount of game media,
when the multiplying-factor symbol colored the predetermined color
(for example, red) or the multiplying-factor symbol having a
background colored the predetermined color (hereinafter, also
simply referred to the multiplying-factor symbol colored the
predetermined color) is stop-displayed by the
multiplying-factor-symbol display device.
[0025] Therefore, it is possible to enhance interests and concern
of the player for the stop-display especially of the
multiplying-factor symbol colored the predetermined color out of
the multiplying-factor symbols. Further, the stop-display of the
multiplying-factor symbol colored the predetermined color pleases
the player, while stop-display of a multiplying-factor symbol
differently colored from the predetermined color disappoints the
player. In this way, it is possible to give the player an
experience of emotional ups and downs by the colors of the
multiplying-factor symbols, thereby resulting in immersion of the
player in games.
[0026] Further, the slot machine of the present invention
preferably has the following configuration.
[0027] That is, the processing (C) is processing for
stop-displaying the multiplying-factor symbol by the
multiplying-factor-symbol display device, after rearranging the
plurality of the normal symbols in the processing (A).
[0028] As described above, according to the aforementioned slot
machine, the multiplying-factor symbol is stop-displayed by the
multiplying-factor-symbol display device, after rearranging the
normal symbols to the display. That is, the multiplying factor for
multiplication of the normal symbol is determined, after the player
recognizes the normal payout amount (the amount paid out for the
established prize). Therefore, the player greatly may expect or may
not expect so much the stop-display of a multiplying-factor symbol
having a large number displayed thereon, depending on the amount
paid out for the established prize.
[0029] For example, when the normal symbols rearranged in the
symbol matrix SM results in establishment of a prize that offers a
large amount of a payout, the player waits for stop-display of a
multiplying-factor symbol having a larger number displayed thereon,
with expectation for a further increase in the amount of the
payout. On the contrary, when the normal symbols rearranged to the
display results in no payout, since even stop-display of a
multiplying-factor symbol having a large number displayed thereon
only results in no increase in an amount of a payout, the player
does not expect the stop-display of a multiplying-factor symbol
having a large number displayed thereon.
[0030] As described above, which normal symbols are rearranged in
the display causes ups and downs in the sense of expectation for
the stop-display of a multiplying-factor symbol having a large
number displayed thereon, resulting in further enhancement of
entertainment of the games.
[0031] Further, the slot machine of the present invention
preferably has the following configuration.
[0032] That is, the processing (D-1) is processing for paying out
game media in amount obtained by multiplying the normal payout
amount determined in the processing (B-1) by the number displayed
on the multiplying-factor symbol stop-displayed in the processing
(C), on condition that the normal symbols rearranged in the
processing (A) or a combination thereof satisfy a predetermined
condition.
[0033] Thus, according to the aforementioned slot machine, the
player can acquire a several times larger amount of game media, on
condition that rearranged normal symbols or a combination thereof
satisfy the specific condition (for example, rearrangement of a
predetermined number or more of predetermined symbols,
establishment of a specific combination by predetermined nine
symbols).
[0034] Accordingly, the player has a lot of interests in whether or
not the specific condition is established, and this configuration
can lead the player to have a lot of interests in whether or not
the specific condition is established as well as which prize is
established by rearranged symbols. Therefore, it is possible to
enhance interests of the player in symbols to be rearranged and
also to immerse the player in the games.
[0035] Further, the slot machine of the present invention
preferably has the following configuration.
[0036] That is, the processing (A) comprises processing of: (A-1)
rearranging a plurality of normal symbols to the display after
coins are BET; and (A-2) rearranging a plurality of normal symbols
even without coins BET, on condition that the normal symbols
rearranged in the processing (A-1) or a combination thereof satisfy
the predetermined condition. Further, the processing (B-1)
comprises processing of: (B-1-1) determining the normal payout
amount, based on the numbers of the normal symbols of respective
types rearranged in the processing (A-1); and (B-1-2) determining
the normal payout amount, based on the numbers of the normal
symbols of respective types rearranged in the processing (A-2).
Further, the processing (D-1) is processing for paying out game
media in amount obtained by multiplying the normal payout
determined in the processing (B-1-2) by the number displayed on the
multiplying-factor symbol stop-displayed in the processing (C).
[0037] Further, according to the aforementioned slot machine, in
case of the establishment of the specific condition, the plurality
of normal symbols are rearranged and the normal payout amount is
determined, even without coins BET. That is, free games are
conducted in the event of the establishment of the specific
condition. During the free games, the player can acquire a several
times larger amount of game media than the amount of game media
that the player can acquire in games other than free games (also
referred to normal games in the present specification).
[0038] Therefore, since the player can play game without BETTING
game media and also acquire a several times larger amount of a
payout, it is possible to further enhance interests and concern of
the player for the specific condition that generates free games. As
a result, this configuration can immerse the player in the
games.
[0039] The present invention provides a slot machine having the
following configuration.
[0040] That is, the aforementioned slot machine comprises a
display, a multiplying-factor-symbol display device and a
controller. The display is capable of rearranging a plurality of
normal symbols. The multiplying-factor-symbol display device is
capable of varying and displaying a plurality of multiplying-factor
symbols each having a different number from one another displayed
thereon. The controller is programmed to execute processing of:
[0041] (A) rearranging the plurality of normal symbols to the
display;
[0042] (B-2) determining, based on the numbers of the normal
symbols of respective types rearranged in the processing (A),
individual payout amounts for the respective types;
[0043] (C) stop-displaying a single multiplying-factor symbol by
the multiplying-factor-symbol display device, after varying and
displaying the multiplying-factor symbols; and
[0044] (D-2) paying out a special amount of game media and a normal
amount of game media, the special payout amount being obtained by
multiplying an amount obtained by summing the individual payout
amounts for the types satisfying a predetermined condition by the
number displayed on the multiplying-factor symbol stop-displayed in
the processing (C), the standard payout amount being obtained by
summing the individual payout amounts for types failing to satisfy
the predetermined condition.
[0045] As described above, according to the aforementioned slot
machine, a single multiplying-factor symbol is stop-displayed by
the multiplying-factor-symbol display device, after the
multiplying-factor symbols are varied and displayed. Each of the
multiplying-factor symbols has a number displayed thereon. Then, a
special amount of game media and a standard amount of game media
are paid out. Here, the special payout amount is obtained by
multiplying an amount obtained by summing the individual payout
amounts for the types of the symbols satisfying the predetermined
condition by the number corresponding to the multiplying-factor
symbol, and the standard payout amount is obtained by summing the
individual payout amounts for the types failing to satisfy the
predetermined condition.
[0046] As described above, according to the aforementioned slot
machine, the player can acquire a several times larger amount of
game media for the types of the normal symbols satisfying the
predetermined condition, based on the stop-display of the
multiplying-factor symbol stop-displayed by the
multiplying-factor-symbol display device, resulting in enhancement
of a sense of expectancy of the player for payouts. Therefore, it
is possible to prevent the player from losing a sense of expectancy
for payouts.
[0047] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire is stop-displayed, it is possible to lead the player to
have interests and concern for the number displayed on the
multiplying-factor symbol to be stop-displayed. Furthermore, since
the player plays games with a great sense of expectancy for
stop-display of a multiplying-factor symbol having a larger number
displayed thereon, it is possible to prevent the player from
getting bored with games soon.
[0048] Furthermore, since only the payout amounts for the types of
the normal symbols satisfying the predetermined condition are
increased several-fold, it is possible to lead the player to have
interests and concern for whether or not the respective normal
symbols satisfy the predetermined condition.
[0049] Further, the slot machine of the present invention
preferably has the following configuration.
[0050] That is the normal symbols and the multiplying-factor
symbols are colored or have a colored background. The processing
(D-2) comprises processing of: (D-2-1) determining the special
payout amount by multiplying an amount obtained by summing
individual payout amounts for types of normal symbols colored the
same or having a background colored the same as a color of the
multiplying-factor symbol rearranged in the processing (C) or a
color of the background of the multiplying-factor symbol, by the
number displayed on the multiplying-factor symbol; (D-2-2)
determining the standard payout amount by summing individual payout
amounts for types other than the types; and (D-2-3) paying out the
special payout amount of game media determined in the processing
(D-2-1) and the standard payout amount of game media determined in
the processing (D-2-2).
[0051] As described above, according to the aforementioned slot
machine, the player can acquire a several times larger amount of
game media for the normal symbols colored the same as the color of
the multiplying-factor symbol stop-displayed by the
multiplying-factor-symbol display device or the normal symbols
having a background colored the same (hereinafter, also referred to
normal symbols colored the same).
[0052] Therefore, the player have a lot of fun in checking which
normal symbols have the same color as that of the
multiplying-factor symbol, during playing games. Such an action as
checking allows the player to immerse in the games.
[0053] Further, the slot machine of the present invention
preferably has the following configuration.
[0054] That is, the processing (C) is processing for
stop-displaying the multiplying-factor symbol by the
multiplying-factor-symbol display device, after rearranging the
plurality of the normal symbols in the processing (A).
[0055] As described above, according to the aforementioned slot
machine, the multiplying-factor symbol is stop-displayed by the
multiplying-factor-symbol display device, after rearranging the
normal symbols to the display. That is, the multiplying factor for
multiplication of the total sum of the individual payout amounts
for the types of the symbols satisfying the predetermined condition
is determined, after the player recognizes the individual payout
amounts for the respective types of the symbols (the amounts paid
out for the established prizes). Therefore, the player may greatly
expect or may not expect so much the stop-display of a
multiplying-factor symbol having a large number displayed thereon,
depending on the amounts paid out for the established prizes.
[0056] For example, when normal symbols rearranged to the display
results in establishment of a prize that offers a large amount of a
payout, the player waits for the rearrangement of a
multiplying-factor symbol having a larger number displayed thereon
with expectation for a further increase in the amount of the
payout. In addition, the player expects that the symbols
constituting the prize satisfy the predetermined condition. On the
contrary, when the normal symbols rearranged to the display results
in no payout, since even stop-display of a multiplying-factor
symbol having a large number displayed thereon only results in no
increase in an amount of a payout, the player does not expect the
stop-display of a multiplying-factor symbol having a large number
displayed thereon.
[0057] As described above, which normal symbols are rearranged in
the first display area causes ups and downs in the sense of
expectation for the stop-display of a multiplying-factor symbol
having a large number displayed thereon, resulting in further
enhancement of entertainment of the games.
[0058] Further, the slot machine of the present invention
preferably has the following configuration.
[0059] That is, the processing (D-2) is processing for paying out
the special amount of game media and the standard amount of game
media, on condition that the normal symbols rearranged in the
processing (A) or a combination thereof satisfy a predetermined
condition, the special payout amount being obtained by multiplying
an amount obtained by summing the individual payout amounts for the
types satisfying the predetermined condition by the number
displayed on the multiplying-factor symbol stop-displayed in the
processing (C), the standard payout amount being obtained by
summing the individual payout amounts for types failing to satisfy
the predetermined condition.
[0060] Further, according to the aforementioned slot machine, the
player can acquire a several times larger amount of game media for
the types of the normal symbols satisfying the predetermined
condition, on condition that rearranged normal symbols or a
combination thereof satisfies the specific condition (for example,
rearrangement of a predetermined number or more of predetermined
symbols, establishment of a specific combination by predetermined
nine symbols).
[0061] Accordingly, the player has a lot of interests in whether or
not the specific condition is established, and this configuration
can lead the player to have a lot of interests in whether or not
the specific condition is established as well as which prize is
established by rearranged symbols. Therefore, it is possible to
enhance interests of the player in symbols to be rearranged and
also to immerse the player in the games.
[0062] Further, the present invention provides a slot machine
having the following configuration.
[0063] That is, the processing (A) comprises processing of: (A-1)
rearranging a plurality of normal symbols to the display after
coins are BET, and (A-2) rearranging a plurality of normal symbols
even without coins BET, on condition that the normal symbols
rearranged in the processing (A) or a combination thereof satisfy
the predetermined condition. Further, the processing (B-2)
comprises processing of: (B-2-1) determining the individual payout
amounts for the respective types, based on the numbers of the
normal symbols of respective types rearranged in the processing
(A-1); and (B-2-2) determining the individual payout amounts for
the respective types, based on the numbers of the normal symbols of
respective types rearranged in the processing (A-2). Further, the
processing (D-2) is processing for paying out the special amount of
game media and the standard amount of game media, the special
payout amount being obtained by multiplying an amount obtained by
summing the individual payout amounts for types satisfying the
predetermined condition by the number displayed on the
multiplying-factor symbol stop-displayed in the processing (C) out
of the individual payout amounts for the respective types
determined in the processing (B-2-2), the standard payout amount
being obtained by summing the individual payout amounts for types
failing to satisfy the predetermined condition out of the
individual payout amounts determined in the processing (B-2-2)
[0064] Further, according to the aforementioned slot machine, in
case of establishment of the specific condition, a plurality of
normal symbols are rearranged and the normal payout amount is
determined, even without coins BET. That is, free games are
conducted in the event of the establishment of the specific
condition. During the free games, the player can acquire a several
times larger amount of game media than the amount of game media
which the player can acquire in games other than free games (also
referred to normal games in the specification), for the types of
the normal symbols satisfying the predetermined condition.
[0065] Therefore, since the player can play game without BETTING
game media and also acquire a several times larger amount of a
payout for the types of the normal symbols satisfying the
predetermined condition, it is possible to further enhance
interests and concern of the player for the specific condition that
generates free games. As a result, this configuration can immerse
the player in the games.
[0066] Further, the present invention provides a controlling method
of a slot machine having the following configuration.
[0067] That is, the controlling method of a slot machine comprises
steps of: (A) rearranging a plurality of normal symbols to the
display; (B-1) determining a normal payout amount, based on the
numbers of the normal symbols of respective types rearranged in the
processing (A); (C) stop-displaying a single multiplying-factor
symbol by the multiplying-factor-symbol display device, after
varying and displaying the multiplying-factor symbols; and (D-1)
paying out game media in amount obtained by multiplying the normal
payout amount determined in the processing (B-1) by the number
displayed on the multiplying-factor symbol stop-displayed in the
processing (C).
[0068] According to the aforementioned controlling method of a slot
machine, a single multiplying-factor symbol is stop-displayed by
the multiplying-factor-symbol display device, after the
multiplying-factor symbols are varied and displayed. Each of the
multiplying-factor symbols has a number displayed thereon. Further,
game media in amount obtained by multiplying the normal payout by
the number displayed on the multiplying-factor symbol are paid
out.
[0069] As described above, according to the aforementioned
controlling method of a slot machine, the player can acquire
several times larger amount of game media, based on the
multiplying-factor symbol stop-displayed by the
multiplying-factor-symbol display device, resulting in enhancement
of a sense of expectancy of the player for payouts. Therefore, it
is possible to prevent the player to lose a sense of expectancy for
payouts.
[0070] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire is stop-displayed, it is possible to lead the player to
have interests and concern for the number of the multiplying-factor
symbol to be stop-displayed. Furthermore, since the player plays
games with a great sense of expectancy for stop-displaying of a
multiplying-factor symbol having a larger number displayed thereon,
it is possible to prevent the player from getting bored with games
soon.
[0071] Further, the present invention provides a controlling method
of a slot machine having the following configuration.
[0072] That is, the controlling method of a slot machine comprises
steps of: (A) rearranging a plurality of normal symbols to the
display; (B-2) determining, based on the numbers of the normal
symbols of respective types rearranged in the processing (A),
individual payout amounts for the respective types; (C)
stop-displaying a single multiplying-factor symbol by the
multiplying-factor-symbol display device, after varying and
displaying the multiplying-factor symbols; and (D-2) paying out a
special amount of game media and a normal amount of game media, the
special payout amount being obtained by multiplying an amount
obtained by summing the individual payout amounts for the types
satisfying a predetermined condition by the number displayed on the
multiplying-factor symbol stop-displayed in the processing (C), the
standard payout amount being obtained by summing the individual
payout amounts for types failing to satisfy the predetermined
condition.
[0073] As described above, according to the aforementioned
controlling method of a slot machine, a single multiplying-factor
symbol is stop-displayed by the multiplying-factor-symbol display
device, after the multiplying-factor symbols are varied and
displayed. Each of the multiplying-factor symbols has a number
displayed thereon. Then, a special amount of game media and a
standard amount of game media are paid out. Here, the special
payout amount is obtained by multiplication of an amount obtained
by summing the individual payout amounts for the types of the
symbols satisfying the predetermined condition by the number
corresponding to the multiplying-factor symbol, and the standard
payout amount is obtained by summing the individual payout amounts
for the types failing to satisfy the predetermined condition.
[0074] As described above, according to the aforementioned
controlling method of a slot machine, the player can acquire a
several times larger amount of game media for the types of the
normal symbols satisfying the predetermined condition, based on the
stop-display of the multiplying-factor symbol stop-displayed by the
multiplying-factor-symbol display device, resulting in enhancement
of a sense of expectancy of the player for payouts. Therefore, it
is possible to prevent the player from losing a sense of expectancy
for payouts.
[0075] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire is stop-displayed, it is possible to lead the player to
have interests and concern for the number displayed on the
multiplying-factor symbol to be stop-displayed. Furthermore, since
the player plays games with a great sense of expectancy for
stop-display of a multiplying-factor symbol having a larger number
displayed thereon, it is possible to prevent the player from
getting bored with games soon.
[0076] Furthermore, since only the payout amounts for the types of
the normal symbols satisfying the predetermined condition are
increased several-fold, it is possible to lead the player to have
interests and concern for whether or not the respective normal
symbols satisfy the predetermined condition.

DESCRIPTION OF THE EMBODIMENTS
First Embodiment
[0101] In a slot machine 10 (see FIG. 3) according to the first
embodiment, a multiplying-factor symbol (for example, a red
multiplying-factor symbol 102 (see FIG. 1C) or a yellow
multiplying-factor symbol 104 (see FIG. 1D)) is rearranged in a
symbol matrix SM. In addition, by a multiplying-factor reel 106
(see FIG. 3), a multiplying-factor symbol (a multiplying-factor
symbol 108 for free games (see FIG. 1F)) is stop-displayed. Thus,
in the first embodiment, two types of multiplying-factor symbols
are used. Hereinafter, the multiplying-factor symbol rearranged in
the symbol matrix SM is also referred to a multiplying-factor
symbol for the symbol matrix SM. Further, hereinafter, the
multiplying-factor symbol stop-displayed by the multiplying-factor
reel 106 is also referred to a multiplying-factor symbol for the
multiplying-factor reel.
[0102] Out of these multiplying-factor symbols, the
multiplying-factor symbol for the multiplying-factor reel
corresponds to the multiplying-factor symbol in the present
invention. The multiplying-factor reel 106 corresponds to the
multiplying-factor-symbol display device.
[0103] When the multiplying-factor symbol for the symbol matrix SM
or the multiplying-factor symbol for the multiplying-factor reel is
rearranged or stop-displayed, based on the number N (the symbol N
is an integral number of 2 or more) displayed on the rearranged or
stop-displayed multiplying factor symbol, the number of coins to be
offered to a player increases N-fold at the maximum.
[0104] Hereinafter, with reference to FIGS. 1 and FIG. 2, the
outline of the first embodiment will be described.
[0105] FIGS. 1A and 1B are views each illustrating an exemplary
symbol matrix.
[0106] Each symbol matrix SM illustrated in FIGS. 1A and 1B is the
symbol matrix SM displayed to a lower image display panel 16 (the
display of the present invention) provided in the slot machine 10
(see FIG. 3). The symbol matrix SM is constituted by a
normal-symbol display area 100 and a multiplying-factor-symbol
display area 101. The normal-symbol display area 100 is capable of
rearranging a total of 12 symbols along 3 rows and 4 columns. The
multiplying-factor-symbol display area 101 is capable of displaying
three normal symbols or a combination of two normal symbols and a
single multiplying-factor symbol.
[0107] Hereinafter, both of the normal symbols and the
multiplying-factor symbols are simply referred to symbols.
[0108] When the player presses a start button 23 (see FIG. 3)
provided in the slot machine 10, scrolling of symbols starts in the
symbol matrix SM, as illustrated in FIG. 1A.
[0109] Subsequently, 15 normal symbols or a combination of 14
normal symbols and a single multiplying-factor symbol are
rearranged. The symbols are rearranged in either of the following
two patterns.
[0110] Pattern I: After rearranging 12 normal symbols in the
normal-symbol display area 100, three normal symbols or a
combination of two normal symbols and a single multiplying-factor
symbol are rearranged in the multiplying-factor-symbol display area
101.
[0111] Pattern II: After rearranging three normal symbols or a
combination of two normal symbols and a single multiplying-factor
symbol in the multiplying-factor-symbol display area 101, 12 normal
symbols are rearranged in the normal-symbol display area 100.
[0112] FIG. 1B illustrates the case where symbols are rearranged in
Pattern I.
[0113] Which pattern to be employed in the rearrangements is
determined based on operation of timing selection buttons 110A,
110B (see FIG. 3) by the player, or types and the number of normal
symbols to be rearranged. Hereinafter, the pattern of the
rearrangements determined based on operation of the timing
selection buttons 110A, 110B or the types and the number of normal
symbols to be rearranged is also referred to "setting of
timing".
[0114] First, there will be described a case where timing is set by
operation of the timing setting buttons 110A, 110B.
[0115] The slot machine 10 is provided with a last-rearrangement
selection button 110A and a first-rearrangement selection button
110B (see FIG. 3). Hereinafter, these two buttons together are also
referred to timing selection buttons 110. The player can select a
single timing by pressing one of the timing selection buttons
110.
[0116] In the case where the last-rearrangement selection button
110A is pressed, Pattern I is determined as the pattern of the
rearrangements. That is, the press of the last-rearrangement
selection button 110A by the player means that the rearrangements
are set in such a manner that after rearranging the normal symbols
in the normal-symbol display area 100, a multiplying-factor symbol
is rearranged in the multiplying-factor-symbol display area
101.
[0117] On the other hand, in the case where the first-rearrangement
selection button 110B is pressed, Pattern II is determined as the
pattern of the rearrangements. That is, the press of the
first-rearrangement selection button 110B by the player means that
the rearrangements are set in such a manner that before the
rearranging the normal symbols in the normal-symbol display area
100, a multiplying-factor symbol is rearranged in the
multiplying-factor-symbol display area 101.
[0118] In the case where neither of the last-rearrangement
selection button 110A nor the first-rearrangement selection button
110B is pressed, the pattern of the rearrangement is determined
based on the types and the number of normal symbols to be
rearranged.
[0119] Hereinafter, timing setting in this case will be
described.
[0120] When the start button 23 provided in the slot machine 10 is
pressed by the player, symbols to be rearranged in the symbol
matrix SM are determined using random numbers. Then, based on the
normal symbols determined to be rearranged, a normal payout amount
is determined. When the normal payout amount is equal to or less
than a predetermined amount, Pattern I is determined as the pattern
of the rearrangements. On the other hand, when the amount of the
payout is more than the predetermined amount, Pattern II is
determined as the pattern of the rearrangements.
[0121] Here, a calculation method of payout amounts will be
described with reference to FIGS. 1C, 1D, and FIG. 2. The normal
payout amount and individual payout amounts will also be
described.
[0122] FIGS. 1C and 1D are views each illustrating an exemplary
image displayed to the lower image display panel.
[0123] FIG. 2 is a view illustrating the relationships between the
numbers of rearranged normal symbols and amounts of individual
payouts.
[0124] As illustrated in FIG. 2, the individual payout amounts are
determined so as to correspond to types and the numbers of
rearranged normal symbols. In FIG. 2, "10", "J", "Q", "K",
"UMBRELLA", "CLOUD", "THUNDER", and "SUN" are illustrated as
examples of the normal symbols. The normal symbols of the present
embodiment are constituted by so-called scatter symbols.
[0125] For example, as illustrated in FIG. 1C, when three "SUNs"
are rearranged, the individual payout amount is an amount
corresponding to 50 coins. Further, when four "Ks" are rearranged,
the individual payout amount is an amount corresponding to 30
coins. Furthermore, when two "Qs" are rearranged, the individual
payout amount is an amount corresponding to 30 coins.
[0126] As described above, the individual payout amounts are
calculated for the respective types of the normal symbols.
[0127] The normal payout amount is an amount obtained by adding the
individual payout amounts for the respective types of the symbols.
In the example illustrated in FIG. 1C, the normal payout amount is
an amount corresponding to 50+30+30=110 coins (see
number-of-payouts display section 103 of FIG. 1C)
[0128] As described above, when a multiplying-factor symbol is
rearranged in the multiplying-factor-symbol display area 101, the
payout amount increases N-fold at the maximum. In the present
embodiment, each multiplying-factor symbol and each normal symbol
have one of colors of red, blue and yellow. A degree of increase of
the payout amount changes according to the colors of the rearranged
symbols.
[0129] A red multiplying-factor symbol 102 is rearranged in the
symbol matrix SM in the example illustrated in FIG. 1C. Although,
in this example, the characters "RED" are displayed on the red
multiplying-factor symbol 102, these characters are illustrated
only for convenience of the description. In actual, the red
multiplying factor symbol 102 has characters of ".times.3" that is
colored red.
[0130] With respect to this point, a yellow multiplying factor
symbol 104 in FIG. 1D is also illustrated in the same way.
[0131] As illustrated in FIG. 1C, in the case where the red
multiplying-factor symbol 102 is rearranged, coins corresponding to
the three-fold of the normal payout amount are paid out to the
player regardless of colors of rearranged normal symbols (see
number-of-payouts display section 103 of FIG. 1C)
[0132] On the other hand, as illustrated in FIG. 1D, when the
yellow multiplying-factor symbol 104 is rearranged, normal symbols
having a yellow color that is the same color as that of the yellow
multiplying-factor symbol 104 (hereinafter, simply referred to
"normal symbol colored the same") are identified out of normal
symbols rearranged in the symbol matrix SM.
[0133] In the example illustrated in FIG. 1D, the normal symbols
enclosed by a frame represent symbols colored yellow. In this case,
similarly, the normal symbols are illustrated as being enclosed by
the frame for indicating which normal symbols are colored yellow
for convenience of the description. However, in actual, the normal
symbols are not displayed in such a way that they are enclosed by a
frame. In actual, the normal symbols themselves have a color, so
that the player can immediately recognize which normal symbols have
the yellow color, without a frame for enclosing the normal
symbols.
[0134] When the normal symbols colored the same are identified,
coins corresponding to the three-fold of the total sum of
individual payout amounts for respective types of the normal
symbols colored the same are paid out to the player. With respect
to the normal symbol having a different color from that of the
yellow multiplying factor symbol 104 (hereinafter, simply referred
to "normal symbol differently colored"), coins corresponding to the
total sum of the individual payout amounts for respective types of
the normal symbols differently colored (without 3-fold
multiplication) are paid out to the player (see the
number-of-payouts display section 103 in FIG. 1D).
[0135] The calculation method of payout amounts has been described
with reference to FIGS. 1C, 1D, and FIG. 2.
[0136] Next, free games conducted in the present embodiment will be
described with reference to FIGS. 1E to 1H.
[0137] FIGS. 1E to 1H are views each illustrating an exemplary
image displayed to the lower image display panel.
[0138] In the period of the free games, although game media are not
BET, slot machine games are conducted. In the present
specification, the slot machine game conducted in a period other
than the period of free games is also referred to a normal
game.
[0139] In the present embodiment, when three or more normal symbols
"BONUSs" (see FIG. 2) are rearranged, free games generate.
[0140] In case of the rearrangement of three or more normal symbols
"BONUSs", the multiplying-factor symbols are varied and displayed
in a multiplying-factor-symbol display area 105, as illustrated in
FIG. 1E.
[0141] The multiplying-factor reel 106 is rotatably provided within
the cabinet 11 (see FIG. 3) included in the slot machine 10. The
symbol sequence constituted by a plurality of multiplying-factor
symbols (characters of ".times.N" (the symbol N is an integer of 2
or larger)) is drawn on the outer peripheral surface of the
multiplying-factor reel 106. In the multiplying-factor-symbol
display area 105, there are formed a display window visible through
its back surface, and a multiplying-factor symbol drawn on the
outer peripheral surface of the multiplying-factor reel 106 is
displayed through the display window.
[0142] As illustrated in FIG. 1E, after varying and displaying of
the plurality of multiplying-factor symbols, a single
multiplying-factor symbol is stop-displayed. In the example
illustrated in FIG. 1F, a multiplying-factor symbol 108 for free
games on which characters of ".times.10" are displayed is
stop-displayed. In this example, a multiplying-factor for free
games is determined to be 10. The multiplying factor for free games
is a value referred when a payout amount is determined in free
games.
[0143] As illustrated in FIG. 1G, in a
multiplying-factor-for-free-games display area 107, an image of
characters indicative of the multiplying factor for free games is
displayed during the free games.
[0144] As illustrated in FIG. 1H, in free games, coins
corresponding to an amount obtained by multiplying a payout amount
in a normal game by the multiplying factor for free games is paid
out (see the number-of-payouts display section 103)
[0145] There has been described the outline of the first
embodiment, with reference to FIGS. 1A to 1H and FIG. 2.
[0146] Hereinafter, the first embodiment will be described in more
detail.
[0147] FIG. 3 is a perspective view illustrating the external
appearance of the slot machine.
[0148] In the slot machine 10, a coin, a bill, or electronic
valuable information corresponding thereto is used as a game
medium. However, in the present invention, a game medium is not
particularly limited. Examples of the game medium may include a
medal, a token, electronic money, or a ticket. It should be noted
that the ticket is not particularly limited, and examples thereof
include a ticket with a bar code, which will be described
later.
[0149] Here, the slot machine 10 is a standalone type slot machine
that is not connected to a network, but the present invention can
also be applied to a slot machine connected to a network.
[0150] The slot machine 10 includes: a cabinet 11; a top box 12
placed on the upper side of the cabinet 11; and a main door 13
provided at the front face of the cabinet 11. The lower image

panel 16 corresponds to the display of the present invention. In
the lower image display panel 16, there are provided a
number-of-credits display section 31 (not shown). The
number-of-credits display section 31 displays an image indicating
the number of credited coins.
[0151] In addition, as described above, there are provided the
multiplying-factor-symbol display area 105 in the lower image
display panel 16, and the player is allowed to see a
multiplying-factor symbol displayed by the multiplying-factor reel
106.
[0152] Further, a touch panel 69, which is not shown in the figure,
is provided on the front face of the lower image display panel 16,
and the player can input various kinds of commands by operating the
touch panel 69.
[0153] Below the lower image display panel 16, there are provided a

[0154] The control panel 20 is provided with a start button 23, a
change button 24, a CASHOUT button 25, a 1-BET button 26, and a
maximum BET button 27. The start button 23 is used for inputting a
command to start a game. The change button 24 is used for making a
request of staff at a recreation facility for exchange. The CASHOUT
button 25 is used for inputting a command to pay out credited coins
to a coin tray 18.
[0155] The 1-BET button 26 is used for inputting a command to BET
one coin on a game out of credited coins. The maximum BET button 27
is used for inputting a command to BET the maximum number (10 in
the present embodiment) of coins that can be bet on a single game
out of credited coins.
[0156] In addition, the last-rearrangement selection button 110A
and the first-rearrangement selection button 110B are provided on
the control panel 20. As described above, the player is allowed to
select a single pattern out of Pattern I and Pattern II as the
timing of the rearrangement of symbols by pressing either one of
these timing selection buttons 110.
[0157] The bill validator 22 not only discriminates a regular bill
from a false bill, but also accepts the regular bill into the
cabinet 11. It should be noted that the bill validator 22 may be
configured so as to be capable of reading a later-described ticket
39 with a barcode. At the lower front face of the main door 13,
namely below the control panel 20, there is provided a belly glass
34 on which a character or the like of the slot machine 10 is
drawn.
[0158] At the front face of the top box 12, an upper image display
panel 33 is provided. The upper image display panel 33 is provided
with a liquid crystal panel to display, for example, an image
representing an introduction of the contents of a game or a
description of a rule of the game.
[0159] Further, the top box 12 is provided with a speaker 29. Below
the upper image display panel 33, there are provided a ticket
printer 35, a card reader 36, a data display 37, and a keypad 38.
The ticket printer 35 prints on a ticket a barcode as coded data of
the number of credits, date and time, an identification number of
the slot machine 10, and the like, and outputs the ticket as a
ticket 39 with a barcode. The player can make another slot machine
read the ticket 39 with a barcode to play a game thereon, or can
exchange the ticket 39 with a barcode with bills or the like at a
predetermined place in the recreation facility (for example, a
cashier in a casino).
[0160] The card reader 36 reads data from a smart card and writes
data into the smart card. The smart card is a card owned by the
player, and for example, data for identifying a player and data on
a history of games played by the player are stored therein. Data
corresponding to a coin, a bill, or a credit may be stored in the
smart card. Further, in place of the smart card, a magnetic stripe
card may be adopted. The data display 37 is comprised of a
fluorescent display or the like, and displays, for example, data
read by the card reader 36 or data inputted by the player through
the keypad 38. The keypad 38 is used for inputting a command and
data concerning the issue of a ticket and the like.
[0161] FIG. 4 is a block diagram showing an internal configuration
of the slot machine shown in FIG. 3.
[0162] A gaming board 50 includes a CPU (Central Processing Unit)
51, a ROM 55, and a boot ROM 52 which are interconnected to one
another via an internal bus, a card slot 53S corresponding to a
memory card 53, and an IC socket 54S corresponding to a GAL
(Generic Array Logic) 54.
[0163] The memory card 53 is formed from a nonvolatile memory such
as CompactFlash (registered trademark) and stores game programs and
game system programs. The game programs include a symbol selection
program. The aforementioned symbol selection program is a program
for determining the normal symbols and the multiplying-factor
symbol to be rearranged in the symbol matrix SM and the
multiplying-factor symbol to be stop-displayed by the
multiplying-factor reel 106. The aforementioned symbol selection
program includes symbol weighing data in association with plural
types of payout ratios (for example, 80%, 84%, 88%). The symbol
weighing data is data indicating the correspondence between the
respective symbols, and one or more random numbers which fall in a
predetermined numerical range (0 to 255). The payout ratios are
determined based on payout-ratio setting data outputted from the
GAL 54 and, based on the symbol weighing data associated with the
payout ratios, the symbols to be rearranged in the symbol matrix SM
and a multiplying-factor symbol to be stop-displayed by the
multiplying-factor reel 106 are determined.
[0164] Further, the game programs include table data (see FIG. 2)
indicative of the relationships between the numbers of rearranged
normal symbols and the individual payout amounts.
[0165] Further, the card slot 53S is configured so as to allow the
memory card 53 to be inserted thereinto or ejected therefrom, and
is connected to a mother board 40 via an IDE bus. Thus, the memory
card 53 can be ejected from the card slot 53S, and then another
game program is written onto the memory card 53, and the memory
card 53 can be inserted into the card slot 53S, to change the type
and contents of a game to be played on the slot machine 10. The
game program includes a program associated with the progress of a
game. The game program also includes image data and sound data to
be outputted during the game. The image data includes image data
and the like indicating a symbol matrix.
[0166] The GAL 54 is a type of PLD having a fixed OR array
structure. The GAL 54 includes plural input ports and plural output
ports and, when predetermined data is inputted to an input port,
the GAL 54 outputs data corresponding to the aforementioned data
from an output port. The data outputted from this output port is
the aforementioned payout-ratio setting data.
[0167] Further, the IC socket 54S is configured to allow the GAL 54
to be attached thereto and detached therefrom and is connected to
the motherboard 40 through a PCI bus. Accordingly, the GAL 54 can
be replaced with another GAL 54 to change the payout-ratio setting
data.
[0168] CPU 51, ROM 55 and boot ROM 52 interconnected to one another
via an internal bus are connected to the mother board 40 by PCI
bus.
[0169] The mother board 40 is constructed with a general-purpose
mother board commercially available (a printed circuit board on
which basic parts of a personal computer are mounted) and includes
a main CPU 41, ROM (Read Only Memory) 42 and RAM (Random Access
Memory) 43. The mother board 40 is the controller of the present
invention.
[0170] ROM 42 is constituted of a memory device such as a flash
memory and stores thereon a program such as BIOS (Basic
Input/Output System) executed by the main CPU 41 and permanent
data. When BIOS is executed by the main CPU 41, not only is
initialization processing for predetermined peripheral devices
conducted, but a capture processing for the game program and game
system program stored on the memory card 53 is also started via the
gaming board 50. In the present invention, contents of ROM 42 may
be rewritable or not rewritable.
[0171] RAM 43 stores data and a program used at the time of
operation of the main CPU 41, and various flags. RAM 43 can also
store the game program. RAM 43 further stores data on the number of
credits, the number of coins-in or coins-out for one game, and the
like.
[0172] Further, in the RAM 43, there are provided a
multiplying-factor-for-free-game storage area and a
number-of-free-games storage area. The
multiplying-factor-for-free-game storage area stores data
indicative of a multiplying factor for free games. As described
above, the multiplying factor for free games is a value referred
when a payout amount is determined in the free games. The
number-of-free-games storage area stores data indicative of the
number of remaining free games.
[0173] To the mother board 40, a body PCB (Printed Circuit Board)
60 and a door PCB 80, which will be described later, are connected
through respective USBs. Further, the mother board 40 is connected
with a power supply unit 45.
[0174] The body PCB 60 and the door PCB 80 are connected with
equipment and devices that generate input signals to be inputted to
the main CPU 41, and equipment and devices operations of which are
controlled by control signals outputted from the main CPU 41. The
main CPU 41 executes a game program stored in the RAM 43 based on
an input signal inputted to the main CPU 41, thereby executes the
predetermined arithmetic processing and stores a result thereof in
the RAM 43, or transmits a control signal to each of the equipment
and devices as processing for controlling each of the equipment and
devices.
[0175] To the body PCB 60, there are connected a lamp 30, a hopper
66, a coin detecting portion 67, a graphic board 68, a speaker 29,
a touch panel 69, a bill validator 22, a ticket printer 35, a card
reader 36, a key switch 38S, and a data display 37. The lamp 30
lights up in a predetermined pattern based on a control signal
outputted from the main CPU 41.
[0176] The hopper 66 is installed inside the cabinet 11 and pays
out a predetermined number of coins from the coin payout exit 19 to
the coin tray 18, based on a control signal outputted from the main
CPU 41. The coin detecting portion 67 is provided inside the coin
payout exit 19, and outputs an input signal to the main CPU 41 when
detecting a payout of a predetermined number of coins from the coin
payout exit 19.
[0177] The graphic board 68 controls, based on a control signal
outputted from the main CPU 41, an image display to the upper image
display panel 33 and the lower image display panel 16. The number
of credits stored in RAM 43 is displayed to the number-of-credits
display section 31 (not shown) of the lower image display panel 16.
The number of coins-out is displayed to the number-of-payouts
display section 103 (see FIG. 1C, FIG. 1D and FIG. 1H) of the lower
image display panel 16. An image of characters indicative of a
multiplying factor for free games is displayed in the
multiplying-factor-for-free-games display area 107 (see FIG. 1G)
during the free games. The graphic board 68 is equipped with VDP
(Video Display Processor) which generates image data based on a
control signal outputted from the main CPU 41 and a video RAM which
temporarily stores image data generated by VDP, and of the like
equipments. It should be noted that image data used in generating
image data with VDP is contained in a game program read from the
memory card 53 and stored in RAM 43.
[0178] The bill validator 22 not only discriminates a regular bill
from a false bill, but also accepts the regular bill into the
cabinet 11. When accepting a regular bill, the bill validator 22
outputs an input signal to the main CPU 41, based on the face
amount of the bill. The main CPU 41 stores, in the RAM 43, the
number of credits according to the face amount of the bill
transmitted with the input signal.
[0179] The ticket printer 35 prints on a ticket, based on a control
signal outputted from the main CPU 41, a barcode formed by encoding
data such as the number of credits, date and time, an
identification number of the slot machine 10, and of the like data
stored in the RAM 43, and outputs the ticket as a ticket 39 with a
barcode.
[0180] The card reader 36 reads data from a smart card and
transmits the data to the main CPU 41 or writes data into the smart
card based on a control signal from the main CPU 41. The key switch
38S is provided on the keypad 38, and outputs a predetermined input
signal to the main CPU 41 when the keypad 38 is operated by the
player. The data display 37 displays, based on a control signal
outputted from the main CPU 41, data read by the card reader 36 or
data inputted by the player through the keypad 38.
[0181] To the door PCB 80, there are connected a control panel 20,
a reverter 21S, a coin counter 21C, and a cold cathode tube 81. The
control panel 20 is provided with a start switch 23S corresponding
to the start button 23, a change switch 24S corresponding to the
change button 24, a CASHOUT switch 25S corresponding to the CASHOUT
button 25, a 1-BET switch 26S corresponding to the 1-BET button 26,
and a maximum BET switch 27S corresponding to the maximum BET
button 27. Each of the switches 23S to 27S outputs an input signal
to the main CPU 41 when each of the buttons 23 to 27 corresponding
thereto is operated by the player.
[0182] Further, in the control panel 20, there are provided an
last-rearrangement selection switch 110AS corresponding to the
last-rearrangement selection button 110A, and a first-rearrangement
selection switch 110BS corresponding to the first-rearrangement
selection button 110B. Each of the switches 110AS and 110BS outputs
an input signal to the main CPU 41, when each of the buttons 110A
and 110B corresponding thereto is operated by the player.
[0183] The coin counter 21C is provided inside the coin receiving
slot 21 and discriminates a regular coin from a false coin inserted
into the coin receiving slot 21 by the player. Coins other than
regular coins are discharged from the coin payout exit 19. When the
coin counter 21C detects a regular coin, the coin counter 21C
outputs an input signal to the main CPU 41.
[0184] The reverter 21S operates based on a control signal
outputted from the main CPU 41, and distributes a coin identified
by the coin counter 21C as a regular coin into a cash box (not
shown) or the hopper 66, which are disposed in the slot machine 10.
Specifically, when the hopper 66 is filled with coins, a regular
coin is distributed into the cash box by the reverter 21S. On the
other hand, when the hopper 66 is not filled with coins, the
regular coin is distributed into the hopper 66. The cold cathode
tube 81 functions as a backlight installed on the rear face side of
the lower image display panel 16 and the upper image display panel
33, and lights up based on a control signal to be outputted from
the main CPU 41.
[0185] Next, processing executed on the slot machine 10 will be
described.
[0186] The main CPU 41 reads a game program and executes the game
program to progress a game.
[0187] FIGS. 5A and 5B are flowcharts illustrating a subroutine of
slot machine game execution processing according to the first
embodiment.
[0188] In the slot machine game execution processing, first, the
main CPU 41 determines whether or not a coin has been BET (step
S10) In the processing, the main CPU 41 determines whether or not
to have received an input signal outputted from the 1-BET switch
26S when the 1-BET button 26 is operated or an input signal
outputted from the maximum BET switch 27S when the maximum BET
button 27 is operated. When determining that a coin has not been
BET, the main CPU 41 returns the processing to step S10.
[0189] On the other hand, when determining that a coin has been BET
in step S10, the main CPU 41 executes processing for making a
subtraction from the number of credits stored in the RAM 43,
according to the number of BET coins (step S11) It should be noted
that, when the number of BET coins is larger than the number of
credits stored in the RAM 43, the main CPU 41 does not execute the
processing for making a subtraction from the number of credits
stored in the RAM 43, and returns the processing to step S10. When
the number of BET coins exceeds an upper limit of the number of
coins that can be BET on a single game (10 in the present
embodiment), the main CPU 41 does not execute the processing for
making a subtraction from the number of credits stored in the RAM
43, and the processing is proceeded to step S12.
[0190] Next, the main CPU 41 determines whether or not the start
button 23 has been turned on (step S12). In the processing, the
main CPU 41 determines whether or not to have received an input
signal outputted from the start switch 23S when the start button 23
is pressed.
[0191] When determining that the start button 23 has not been
turned ON, the main CPU 41 returns the processing to step S10. It
should be noted that, when the start button 23 is not turned ON
(for example, when a command to end the game is inputted without
pressing the start button 23), the main CPU 41 cancels a result of
the subtraction obtained in step S11.
[0192] On the other hand, when determining in step S12 that the
start button 23 has been turned ON, the main CPU 41 executes symbol
rearrangement processing (step S13).
[0193] Here, the symbol rearrangement processing will be described
with reference to FIG. 6.
[0194] FIG. 6 is a flowchart illustrating a subroutine of the
symbol rearrangement processing.
[0195] First, the main CPU 41 executes the symbol determination
processing (step S30). In the processing, the main CPU executes the
aforementioned symbol selection program, and determines symbols
(normal symbols or a combination of normal symbols and a
multiplying-factor symbol) to be rearranged in the symbol matrix
SM.
[0196] Next, the main CPU 41 determines individual payout amounts
for respective types of normal symbols determined to be rearranged
(step S31). In the processing, the main CPU 41 counts the numbers
of the normal symbols of the respective types determined to be
rearranged. Subsequently, the main CPU 41 determines the individual
payout amounts for the respective types of the normal symbols,
based on the counted numbers and table data (see FIG. 2) indicative
of the relationships between the numbers of rearranged normal
symbols and amounts of individual payouts. Then, the main CPU 41
stores the determined the individual payout amounts in the RAM
43.
[0197] Next, the main CPU 41 determines the normal payout amount
that is an amount obtained as the total sum of the individual
payout amounts, and stores the normal payout amount in the RAM 43
(step S32).
[0198] Next, the main CPU 41 determines whether or not a
last-rearrangement flag is set (step S33). The last-rearrangement
flag is a flag set in the event that the last-rearrangement
selection 110A is pressed (see step S41 in FIG. 7).
[0199] When determining that the last-rearrangement flag is not
set, the CPU 41 determines whether or not a first-rearrangement
flag is set (step S34). The first-rearrangement flag is a flag set
in the event that the first-rearrangement selection button 110B is
pressed (see step S43 in FIG. 7).
[0200] Here, the last-rearrangement flag and the
first-rearrangement flag will be described with reference to FIG.
7.
[0201] FIG. 7 is a flowchart illustrating a subroutine of the
timing setting processing.
[0202] First, the main CPU 41 determines whether or not the
last-rearrangement selection button 110A is turned "ON" on a
predetermined timing (step S40). In the processing, the main CPU 41
determines whether or not to have received an input signal
outputted from the last-rearrangement selection switch 110AS when
the last-rearrangement selection button 110A is pressed.
[0203] When the CPU 41 determines the last-rearrangement selection
button 110A is turned "ON", the main CPU 41 sets the
last-rearrangement flag in the RAM 43 (step S41).
[0204] When determining in step S40 that the last-rearrangement
selection button 110A is not turned "ON", or after execution of the
processing of step S41, the main CPU 41 determines whether or not
the first-rearrangement selection button 110B is turned "ON" (step
S42). In the processing, the main CPU 41 determines whether or not
to have received an input signal outputted from the
first-rearrangement selection switch 110BS when the
first-rearrangement selection button 110B is pressed.
[0205] When determining that the first-rearrangement selection
button 110B is turned "ON", the main CPU 41 sets the
first-rearrangement flag in the RAM 43 (step S43).
[0206] When determining in step S42 that the first-rearrangement
selection button is not turned "ON", or after execution of the
processing of step S43, the main CPU 41 ends the present
subroutine.
[0207] The last-rearrangement flag and the first-rearrangement flag
have been described with reference to FIG. 7.
[0208] Hereinafter, FIG. 6 will be described again.
[0209] When determining in step S34 that the first-rearrangement
flag is not set, the main CPU 41 determines whether or not the
normal payout amount determined in step S32 is equal to or less
than a predetermined amount (step S35).
[0210] When determining in step S33 that the last-rearrangement
flag is set, or determining in step S35 that the normal payout
amount is equal to or less than the predetermined amount, the main
CPU 41 rearranges 12 normal symbols in the normal symbol display
area 100 (step S36).
[0211] Subsequently, when the main CPU 41 determines in step S30 to
rearrange a multiplying-factor symbol, the multiplying-factor
symbol and two normal symbols are rearranged in the
multiplying-factor-symbol display area 101 (step S37). On the other
hand, when the main CPU determines in step S30 not to rearrange a
multiplying-factor symbol, three normal symbols are rearranged in
the multiplying-factor-symbol display area 101 (step S37).
[0212] When determining in step S34 that the first-rearrangement
flag is set, or determining in step S35 that the normal payout
amount is more than the predetermined amount, the main CPU shifts
the processing to step S38.
[0213] When the main CPU 41 determines in step S30 to rearrange a
multiplying-factor symbol, the main CPU 41 rearranges the
multiplying-factor symbol and two normal symbols in the
multiplying-factor-symbol display area 101 (step S38). On the other
hand, when the main CPU 41 determined in step S30 not to rearrange
a multiplying-factor symbol, the main CPU 41 rearranges three
normal symbols in the multiplying-factor-symbol display area 101
(step S38).
[0214] Subsequently, the main CPU 41 rearranges 12 normal symbols
in the normal-symbol display area 100 (step S39).
[0215] After execution of the processing of step S37 or step S39,
the main CPU 41 ends the present subroutine.
[0216] The symbol rearrangement processing executed in step S13 in
FIG. 5A has been described with reference to FIG. 6.
[0217] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S30 and step S36 to step S39 in cooperation with
one another, the main CPU 41, the ROM 42 and the RAM 43 function as
the controller for executing the processing (A) of the present
invention. Here, step S30 and step S36 to step S39 correspond to
the step (A) of the present invention.
[0218] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S31 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (B-2) of the present invention. Here, step
S31 corresponds to the step (B-2) of the present invention.
[0219] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S32 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (B-1) of the present invention. Here, step
S32 corresponds to the step (B-1) of the present invention.
[0220] After execution of the processing of step S13, the main CPU
41 determines whether or not a prize is established (step S14).
Here, the establishment of a prize means a rearrangement of two or
more of at least one type of the normal symbols "10", "J", "Q",
"K", "UMBRELLA", "CLOUD", "THUNDER" and "SUN" etc. in the symbol
matrix SM (see FIG. 2). In the processing, the main CPU 41
determines whether or not the normal payout amount determined in
step S32 in FIG. 6 is 0.
[0221] When determining that the prize has been established, the
main CPU 41 determines whether or not to have rearranged a
multiplying-factor symbol in the multiplying-factor-symbol display
area 101 of the symbol matrix SM based on the result of step S30 in
FIG. 6 (step S15).
[0222] When determining not to have rearranged a multiplying-factor
symbol, the main CPU 41 pays out coins corresponding to the normal
payout amount determined in step S32 in FIG. 6 (step S16).
[0223] When determining in step S15 to have rearranged a
multiplying-factor symbol, the main CPU 41 determines whether or
not the rearranged multiplying-factor symbol has a predetermined
color (red in the present embodiment) (step S17).
[0224] When determining that the rearranged multiplying-factor
symbol has the predetermined color, the main CPU 41 pays out coins
corresponding to N-fold of the normal payout amount determined in
step S32 in FIG. 6 (step S18). Here, the symbol N represents a
number "N" displayed on the rearranged multiplying-factor
symbol.
[0225] Next, when determining that the multiplying-factor symbol
rearranged in step S17 does not have the predetermined color, the
main CPU 41 identifies normal symbols colored the same as the color
of the rearranged multiplying-factor symbol, out of the rearranged
normal symbols (step S19).
[0226] Next, the main CPU 41 pays out coins corresponding to the
total sum (standard payout amount) of individual payout amounts for
respective types of the normal symbols differently colored from
that of the rearranged multiplying-factor symbol, based on the
individual payout amounts for the respective types of the normal
symbols determined in step S31 (step S20).
[0227] Subsequently, the main CPU 41 pays out coins corresponding
to N-fold (special payout amount)of the total sum of the individual
payout amounts for the respective types of the normal symbols
colored the same as that of the rearranged multiplying-factor
symbol (step S21). Here, the symbol N represents a number "N"
displayed on the rearranged multiplying-factor symbol.
[0228] When determining in step S14 that a prize is not
established, or after execution of the processing of step S16, step
S18 or step S21, the main CPU 41 determines whether or not a
specific condition is established (step S22). In the present
embodiment, the specific condition is the rearrangement of three or
more normal symbols "BONUSs". In the processing, the main CPU 41
determines whether three or more normal symbols "BONUSs" are
rearranged based on the result of step S30 in FIG. 6.
[0229] When determining that the specific condition is not
established, the main CPU 41 ends the present subroutine.
[0230] On the other hand, when determining that the specific
condition is established, the main CPU 41 varies and displays the
multiplying-factor symbols by the multiplying-factor reel 106, and
then stop-displays a single multiplying-factor symbol in the
multiplying-factor-symbol display area 105 (step S23). In the
processing, the main CPU 41 executes a symbol selection program to
determine a multiplying-factor symbol to be stop-displayed, and
stop-displays the determined multiplying-factor symbol by the
multiplying-factor reel 106.
[0231] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S23 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (C) of the present invention. Here, step
S23 corresponds to the step (C) of the present invention.
[0232] Next, the main CPU 41 determines the number displayed on the
stop-displayed multiplying-factor symbol as the multiplying factor
for free games (step S24). In the processing, the main CPU 41
stores the determined multiplying factor for free games in a
predetermined area (multiplying-factor-for-free-game storage area)
of the RAM 43.
[0233] Subsequently, the main CPU 41 executes the free-game
execution processing (step S25), and then ends the present
subroutine.
[0234] Here, the free-game execution processing will be described
with reference to FIGS. 8A and 8B.
[0235] FIGS. 8A and 8B are flowcharts illustrating a subroutine of
the free-game execution processing.
[0236] First, the main CPU 41 sets the
number-of-remaining-free-games T to T=C (C=10, in the present
embodiment) in a predetermined area (number-of-free-games storage
area) of the RAM 43 (step S50).
[0237] Next, the main CPU 41 executes processing of step S51 to
step S60. The processing is almost the same as the processing of
step S12 to step S21 in FIG. 5A.
[0238] In FIG. 8A, only processing of step S55, step S57, step S59
and step S60 are different from those of FIG. 5A. Only the
processing will be described here.
[0239] Specifically, the main CPU 41 pays out, in step S16 in FIG.
5A, coins corresponding to the normal payout amount determined in
step S32 in FIG. 6. On the other hand, the main CPU 41 pays out, in
step S55 in FIG. 8A, coins corresponding to an amount obtained by
multiplying the normal payout amount determined in step S32 in FIG.
6 by the multiplying factor for free games.
[0240] Further, the main CPU 41 pays out, in step S18 in FIG. 5A,
coins corresponding to the N-fold of the normal payout amount
determined in step S32 in FIG. 6. On the other hand, the main CPU
41 pays out, in step S55 in FIG. 8A, coins corresponding to an
amount obtained by multiplying the N-fold of the normal payout
amount determined in step S32 in FIG. 6 by the multiplying factor
for free games.
[0241] Further, the main CPU 41 pays out, in step S20 in FIG. 5A,
coins corresponding to the total sum of the individual payout
amounts determined in step S31 in FIG. 6 for the respective types
of the normal symbols differently colored from the color of the
rearranged multiplying-factor symbol, based on the individual
payout amounts for the respective types of the normal symbols
determined in step S31 in FIG. 6. On the other hand, the CPU 41
pays out, in step S59 in FIG. 8A, coins corresponding to an amount
obtained by multiplication of the individual payout amounts for the
respective types of the normal symbols differently colored from the
color of the rearranged multiplying-factor symbol by the
multiplying factor for free games.
[0242] In addition, the main CPU 41 pays out, in step S21 in FIG.
5A, coins corresponding to the N-fold of the total sum of the
individual payout amounts for the respective types of the normal
symbols colored the same as the color of the rearranged
multiplying-factor symbol, based on the amounts of the individual
payouts for the respective types of the normal symbols determined
in step S31 in FIG. 6. On the other hand, the main CPU 41 pays out,
in step S60 in FIG. 8A, coins corresponding to an amount obtained
by multiplying the N-fold of the total sum of the individual payout
amounts for the respective types of the normal symbols colored the
same as the color of the rearranged multiplying-factor symbol, by
the multiplying factor for free games.
[0243] As described above, the amount of coins to be paid out in
free games is N-fold larger than the amount of coins to be paid out
normal games.
[0244] When determining in step S53 that a prize is not
established, or after execution of the processing of step S55, step
S57 or step S60, the main CPU 41 determines whether or not a
specific condition is established (step S61). The specific
condition is the rearrangement of three normal symbols "BONUSs",
like in the normal games. In the processing, the main CPU 41
determines whether or not three or more normal symbols "BONUSs" are
rearranged based on the result of step S30 in FIG. 6.
[0245] When determining that the specific condition is established,
the main CPU 41 varies and displays the multiplying-factor symbols
by the multiplying-factor reel 106, and then stop-displays a single
multiplying-factor symbol in the multiplying-factor-symbol display
area 105 (step S62).
[0246] Next, the main CPU 41 determines the number displayed on the
stop-displayed multiplying-factor symbol as the new multiplying
factor for free games (step S63). In the processing, the main CPU
41 overwrites and saves the determined multiplying factor for free
games in the predetermined area (multiplying-factor-for-free-game
storage area) in the RAM 43.
[0247] Next, the main CPU 41 sets the
number-of-remaining-free-games T to T=T+C in the
number-of-free-games storage area of the RAM 43 (step S64). Namely,
when the specific condition is established during the free games,
the number of free games is increased.
[0248] When determining in step S61 that the special condition is
not established or after execution of the processing of step S64,
the main CPU 41 sets the number-of-remaining-free-games T to T=T-1,
in the number-of-free-games storage area in the RAM 43 (step
S65).
[0249] Subsequently, the main CPU 41 determines whether or not T is
0 (step S66).
[0250] When determining that T is not 0, the main CPU 41 returns
the processing to step S51. On the other hand, when determining
that T is 0, the main CPU 41 ends the present subroutine.
[0251] The first embodiment has been described.
[0252] In the first embodiment, there has been described the case
where symbols themselves are colored. However, in the present
invention, symbols may have a colored background. Also, there is no
particular limitation on types and the number of colors of the
symbols.
[0253] As described above, according to the slot machine 10 of the
first embodiment, the multiplying-factor symbol may be rearranged
in the symbol matrix SM displayed to the lower image display panel
16. Further, each of the multiplying-factor symbols corresponds to
a number. In case of the rearrangement of the multiplying-factor
symbol colored the predetermined color (red), the player can
acquire several times larger amount of game media.
[0254] As described above, according to the slot machine 10 of the
first embodiment, in case of the rearrangement of the
multiplying-factor symbol colored red, the player can acquire
several times larger amount of game media, resulting in enhancement
of a sense of expectancy of the player for payouts. Therefore, it
is possible to prevent the player to lose a sense of expectancy for
payouts.
[0255] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire may be rearranged, it is possible to lead the player to
have interests and concern for the rearrangement of the
multiplying-factor symbol. Furthermore, since the player plays
games with a great sense of expectancy for the rearrangement of the
multiplying-factor symbol, it is possible to prevent the player
from getting bored with games soon.
[0256] Furthermore, according to the slot machine 10 of the first
embodiment, since the player can acquire a several times larger
amount of game media, in case of the rearrangement of the
multiplying-factor symbol colored red, it is possible to enhance
interests and concern of the player for the rearrangement
especially of the multiplying-factor symbol colored red out of the
multiplying-factor symbols. Further, the rearrangement of the
multiplying-factor symbol colored red pleases the player, while a
rearrangement of a multiplying-factor symbol differently colored
from the red color disappoints the player. In this way, it is
possible to give the player an experience of emotional ups and
downs, thereby resulting in immersion of the player in games.
[0257] Further, according to the slot machine 10 of the first
embodiment, in case of the rearrangement of the multiplying-factor
symbol colored blue or yellow, the player can acquire a several
times larger amount of game media for the normal symbols colored
the same as the color of the multiplying-factor symbol.
[0258] Therefore, the player have a lot of fun in checking which
normal symbols have the same color as that of the
multiplying-factor symbol, during playing games. Such an action as
checking allows the player to immerse in the games.
[0259] As described above, according to the slot machine 10 of the
first embodiment, the multiplying-factor symbol may be displayed
only in the multiplying-factor-symbol display area 101, and is not
displayed in the normal-symbol display area 100 of the symbol
matrix SM.
[0260] Therefore, it is possible to lead the player who is
expecting for the rearrangement of the multiplying-factor symbol to
concentrate on the multiplying-factor-symbol display area 101,
resulting in immersion of the player in the game.
[0261] As described above, according to the slot machine 10 of the
first embodiment, a single multiplying-factor symbol is
stop-displayed after the multiplying-factor symbols are varied and
displayed by the multiplying-factor reel 106. Each of the
multiplying-factor symbols has a number displayed thereon. The
player can acquire a several times larger amount of game media,
based on the number displayed on the stop-displayed
multiplying-factor symbol, resulting in enhancement of a sense of
expectancy of the player for payouts. Therefore, it is possible to
prevent the player to lose a sense of expectancy for payouts.
[0262] Further, since the multiplying-factor symbol capable of
increasing several-fold an amount of game media that the player can
acquire is stop-displayed, it is possible to lead the player to
have interests and concern for stop-display of a multiplying-factor
symbol having a large number displayed thereon. Furthermore, since
the player plays games with a great sense of expectancy for the
number displayed on the multiplying-factor symbol to be
stop-displayed, it is possible to prevent the player from getting
bored with games soon.
[0263] Further, according to the slot machine of the first
embodiment, the player can acquire a several times larger amount of
game media, on condition that rearranged normal symbols or a
combination thereof satisfies the specific condition (rearrangement
of three or more symbol "BONUSs").
[0264] Accordingly, whether or not the specific condition is
established is a matter of interests for the player, and this
configuration can lead the player to have a great interest in
whether or not the specific condition is established as well as
which prize is established by rearranged symbols. Therefore, it is
possible to enhance interests of the player in symbols to be
rearranged and also to immerse the player in the games.
[0265] Further, according to the slot machine of the first
embodiment, free games are conducted in the event of the
establishment of the specific condition. During the free games, the
player can acquire a several times larger amount of game media than
the amount of game media that the player can acquire in the normal
games.
[0266] Therefore, since the player can play game without BETTING
game media and also acquire a several times larger amount of a
payout, it is possible to further enhance interest and concern of
the player for the specific condition that generates free games. As
a result, this configuration can immerse the player in the
games.
[0267] Further, according to the slot machine of the first
embodiment, when a multiplying-factor symbol is rearranged in the
symbol matrix in the free games, the player is offered a payout in
amount obtained by multiplying both of the multiplying factor set
for the multiplying-factor symbol and the multiplying factor for
free games. Accordingly, since the payout amount is significantly
increased in this case, it is possible to significantly enhance a
sense of expectation of the player for the establishment of the
specific condition and the rearrangement of a multiplying-factor
symbol in the symbol matrix SM during the free games.
[0268] Further, according to the slot machine of the first
embodiment, the pattern of the rearrangements is determined based
on the normal payout amount. Specifically, when the normal payout
amount is equal to or less than the predetermined amount, the
multiplying-factor symbol is rearranged in the symbol matrix SM at
the end. Therefore, it is possible to please a player who is
disappointed at establishment of only a prize that offers a small
amount of a payout, by rearranging a multiplying-factor symbol
having a large multiplying factor set therefor at the end.
[0269] Further, according to the slot machine of the first
embodiment, the pattern of the rearrangement of the symbols is
determined, based on the selection of the player, out of the
following patterns: a pattern in which the multiplying-factor
symbol is rearranged after rearranging the normal symbols; and a
pattern in which the normal symbols are rearranged after
rearranging the multiplying-factor symbol. Accordingly, this
configuration allows the player to set the timing of the
rearrangement of the multiplying-factor symbol as he/she likes,
leading to giving satisfaction to the player. Further, this
configuration also allows to the player to change the timing of the
rearrangement of the multiplying-factor symbol at any time during a
game, leading to prevention of the player from getting bored.
[0270] In the above-described example, the description has been
given with the definition of the specific condition as the
rearrangement of three or more normal symbols "BONUSs". However, in
the present invention, the contents of the specific condition are
not particularly limited.
[0271] Hereinafter, a specific condition according to another
embodiment will be described with reference to FIGS. 9A to 9D.
[0272] FIGS. 9A and 9B are views each illustrating an exemplary
symbol matrix.
[0273] FIGS. 9C and 9D are views each illustrating an exemplary
image which is displayed to the lower image display panel.
[0274] In the present embodiment, symbols are rearranged in the
symbol matrix SM in the sequential order of a display area 200A, a
display area 200B, a display area 200C, a display area 200D and a
display area 200E. The multiplying-factor symbol is rearranged in
the display area 200E. The display area 200E corresponds to the
multiplying-factor-symbol display area 101 of the first
embodiment.
[0275] Here, the specific condition of the present embodiment is "a
rearrangement of a specific combination of normal symbols
rearranged in the display area 200B, the display area 200C and the
display area 200D.
[0276] The normal symbols constituting the specific combination
have a colored background. FIG. 9B illustrates a case in which
normal symbols rearranged in the display area 200B and the display
area 200C are the normal symbols constituting the specific
combination.
[0277] Further, when normal symbols rearranged in the display area
200B and the display area 200C are the normal symbols constituting
the specific combination at the time of the rearrangement of normal
symbols in the display area 200A to the display area 200C (that is,
when the game is a ready-to-win state for the specific
combination), a special image is displayed in the display area 200B
to the display area 200D. In the example illustrated in FIG. 9B, an
image indicative of a face is displayed.
[0278] Subsequently, when the rearrangement in the display area
200D results in completion of the specific combination, an image
201 of characters of a win "FREE GAME!" is displayed and indicates
that the specific condition is established and free games will
start (see FIG. 9C). At this time, the special image is kept
displayed.
[0279] On the other hand, when the rearrangement in the display
area 200D does not result in establishment of the special
combination, an image 202 of characters of a loss "SORRY" is
displayed (see FIG. 9D). At this time, display of the special image
ends.
[0280] It should be noted that the special image, the image 201 of
characters of a win and the image 202 of characters of a loss are
included in the above-mentioned game program.
[0281] Further, in the present embodiment, plural kinds of
combinations are set as the specific combination. Each combination
corresponds to a different special image from one another. When the
game gets into a ready-to-win state for a single specific
combination, the slot machine is configured to display the special
image corresponding to the combination.
[0282] FIG. 10 is a flowchart illustrating a subroutine of symbol
rearrangement processing.
[0283] First, the main CPU 41 executes processing of step S130 to
step S132. The processing is the same as the processing of step S30
to step S32 in FIG. 6 and a description thereof will be omitted
here.
[0284] Next, the main CPU 41 rearranges normal symbols in the
display area 200A to the display area 200C in the symbol matrix SM,
based on the result of the symbol determination in step S130 (step
S133).
[0285] Next, the main CPU 41 determines whether or not the game is
in a ready-to-win state for the completion of the specific
combination (step S134). In the processing, the main CPU 41
determines whether or not 6 normal symbols rearranged in the
display area 200B and the display area 200C are the normal symbols
constituting the specific combination.
[0286] When determining that the game is not a ready-to-win state
for the completion of the specific combination, the main CPU
rearranges symbols in the display area 200D and the display area
200E (step S135), based on the result of the symbol determination
in step S130, and ends the present subroutine.
[0287] On the other hand, when determining that the game is in a
ready-to-win state, the main CPU 41 displays the special image
corresponding to the specific combination in the display area 200B
to the display area 200D (step S136).
[0288] Next, the main CPU 41 rearranges symbols in the display area
200D, based on the result of the symbol determination in step S130
(step S137).
[0289] Next, the main CPU 41 determines whether or not the specific
combination is established (step S138). When determining that the
specific combination is established, the main CPU 41 keeps the
special image displayed and displays the image 201 of characters of
a win (step S140).
[0290] On the other hand, when determining that the specific
combination is not completed, the main CPU 41 ends the display of
the special image and displays the image 202 of characters of a
loss (step S139).
[0291] After execution of the processing of step S139 or step S140,
the main CPU 41 rearranges symbols in the display area 200E (step
S141), based on the result of the symbol determination in step
S130, and ends the present subroutine.
[0292] As described above, in the present embodiment, symbols are
rearranged in the sequential order of the display area 200A, the
display area 200B, the display area 200C, the display area 200D and
the display area 200E without execution of the timing setting
described in the first embodiment. Thus, in the present invention,
the slot machine may be configured not to apply determination of
the order of the rearrangement of symbols, based on the operation
of the timing selection button by the player or the types or the
number of normal symbols to be rearranged.
Second Embodiment
[0293] In the description of the first embodiment, the
multiplying-factor symbols include the multiplying-factor symbols
for the symbol matrix SM and the multiplying-factor symbols for the
multiplying-factor reel. However, in the present invention, the
multiplying-factor symbols do not necessarily include the
multiplying-factor symbol for the symbol matrix SM. The slot
machine 10 according to the second embodiment is configured not to
rearrange the multiplying-factor symbol in the symbol matrix
SM.
[0294] Further, in the description of the first embodiment, payouts
are multiplied by the multiplying factor only in the free games,
based on the multiplying-factor symbol for the multiplying-factor
reel. That is, the payouts are multiplied by the multiplying factor
based on the multiplying-factor symbol, on condition of
satisfaction of either of the following conditions: the
rearrangement of three or more of normal symbols "BONUSs"; or "the
rearrangement of the predetermined combination of the normal
symbols rearranged in the display area 200B, the display area 200C
and the display area 200D". However, in the present invention,
execution of multiplication of the payouts by the multiplying
factor based on the multiplying-factor symbol is not limited to the
case of establishment of the specific condition. The slot machine
according to the second embodiment is configured to multiplying
payouts by the multiplying factor based on the multiplying-factor
symbol also in the normal games.
[0295] In the following description, the same components as
components of the slot machine 10 according to the first embodiment
will be given the same reference numerals.
[0296] Further, the parts of the second embodiment to which
description on the first embodiment can be applied will not be
described.
[0297] FIG. 11 is a flowchart illustrating a subroutine of slot
machine game execution processing according to the second
embodiment.
[0298] First, the main CPU 41 executes processing of step S110 to
step S112. The processing is the same as the processing of step S10
to step S12 in FIG. 5A, and a description thereof will be omitted
here.
[0299] Next, the main CPU 41 executes symbol rearrangement
processing (step S113).
[0300] In the processing, at first, the main CPU 41 starts
scroll-display of the symbols in the symbol matrix SM, as
illustrated in FIG. 1A. Then, the main CPU 41 executes the
above-mentioned symbol selection program, determines symbols to be
rearranged, and rearranges the symbols in the symbol matrix SM.
[0301] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S113 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (A) of the present invention. Here, step
S113 corresponds to the step (A) of the present invention.
[0302] Next, the main CPU 41 determines whether or not a prize is
established (step S114). In the processing, the main CPU 41 counts
the number of rearranged normal symbols of the respective types.
Then, the main CPU 41 determines whether or not two or more normal
symbols of a single type have been counted. When determining that a
prize is not established, the main CPU 41 ends the present
subroutine.
[0303] On the other hand, when determining that a prize is
established, the main CPU 41 varies and displays multiplying-factor
symbols by the multiplying-factor reel 106, and then stop-displays
a single multiplying-factor symbol in the multiplying-factor-symbol
display area 105 (step S115). In the processing, the main CPU 41
executes the symbol selection program, determines a
multiplying-factor symbol to be stop-displayed, and stop-displays
the determined multiplying-factor symbol by the multiplying-factor
reel 106.
[0304] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S115 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (C) of the present invention. Here, step
S115 corresponds to the step (C) of the present invention.
[0305] Next, the main CPU 41 determines individual payout amounts
for respective types of rearranged normal symbols (step S116). In
the processing, the main CPU determines the individual payout
amounts for the respective types of the normal symbols, based on
the counted numbers of the rearranged symbols of the respective
types and the table data (see FIG. 2) indicative of the
relationships between the numbers of rearranged normal symbols and
individual payout amounts.
[0306] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S116 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (B-2) of the present invention. Here, step
S116 corresponds to the step (B-2) of the present invention.
[0307] Next, the main CPU 41 determines the normal payout amount
that is an amount obtained as the total sum of the individual
payout amounts (step S117).
[0308] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S117 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (B-1) of the present invention. Here, step
S117 corresponds to the step (B-1) of the present invention.
[0309] Next, the main CPU 41 pays out coins corresponding to the
amount obtained by multiplying the normal payout amount determined
in step S117 by the number displayed on the multiplying-factor
symbol stop-displayed in step S115 (step S118).
[0310] When the main CPU 41, the ROM 42 and the RAM 43 execute the
processing of step S118 in cooperation with one another, the main
CPU 41, the ROM 42 and the RAM 43 function as the controller for
executing the processing (D-1) of the present invention. Here, step
S118 corresponds to the step (D-1) of the present invention.
[0311] Subsequently, the main CPU 41 ends the present
subroutine.
[0312] As described above, according to the slot machine 10 of the
second embodiment, the multiplying-factor symbol is stop-displayed
by the multiplying-factor reel, after rearranging the normal
symbols in the symbol matrix SM. That is, the multiplying factor
for multiplication of the normal payout amount is determined, after
the player recognizes the normal payout amount (the amount paid out
for the established prize). Therefore, the player may greatly
expect or may not expect so much the stop-display of the
multiplying-factor symbol having a large number displayed thereon,
depending on the amount paid out for the established prize.
[0313] For example, when the normal symbols rearranged in the
symbol matrix SM results in establishment of a prize that offers a
large amount of a payout, the player waits for the rearrangement of
a multiplying-factor symbol having a larger number displayed
thereon with expectation for a further increase in the amount of
the payout. On the contrary, when the normal symbols rearranged in
the symbol matrix SM results in no payout, since even stop-display
of a multiplying-factor symbol having a large number displayed
thereon only results in no increase in an amount of a payout, the
player does not expect the stop-display of a multiplying-factor
symbol having a large number displayed thereon.
[0314] As described above, which normal symbols are rearranged in
the symbol matrix SM causes ups and downs in the sense of
expectation for the stop-display of a multiplying-factor symbol
having a large number displayed thereon, resulting in further
enhancement of entertainment of the games.
[0315] In the second embodiment, the multiplying-factor symbols are
varied and displayed by the multiplying-factor reel 106 in every
game, and a payout is conducted by coins corresponding to the
number obtained by multiplying the normal payout amount by the
number displayed on the multiplying-factor symbol stop-displayed.
However, in the present invention, varying and displaying of the
multiplying-factor symbols and stop-display of the
multiplying-factor symbol may not be conducted in every game. For
example, varying and displaying of the multiplying-factor symbols
and stop-display of the multiplying-factor symbol may be conducted
in every predetermined number of games. Further, varying and
displaying of the multiplying-factor symbols and stop-display of
the multiplying-factor symbol may be conducted, only when the
normal payout amount is equal to or more than the predetermined
amount (or equal to or less than the predetermined amount).
[0316] In the first and second embodiments described above, there
have been described the cases where symbols are rearranged in the
symbol matrix SM of the lower image display panel 16 (the slot
machine 10 is a so-called a video slot machine). However, the slot
machine according to the present invention may be configured to
rearrange symbols using so-called mechanical reels.
[0317] FIG. 12 is a perspective view illustrating the general
appearance of a slot machine according to another embodiment.
[0318] In the following description, the components corresponding
to those of the slot machine 10 will be designated by the same
reference numerals.
[0319] Further, the slot machine 310 has substantially the same
external appearance, the same circuit structure and the like as
those of the slot machine 10 and also executes substantially the
same flowcharts as those executed by the slot machine 10, except
that it employs mechanical reels, and, therefore, only the
mechanical reels will be described herein.
[0320] As illustrated in FIG. 12, 5 reels 314 (314A, 314B, 314C,
314D and 314E) are rotatably provided within a cabinet 11. On the
outer peripheral surfaces of the reels 314A, 314B, 314C, 314D and
314E, there are drawn symbol sequences constituted by normal
symbols such as "10", "J", "Q", "K", "UMBRELLA", "CLOUD",
"THUNDER", "SUN" and "BONUS", and multiplying-factor symbols.
[0321] At the center portion of the lower image display panel 16,
there is provided a display area 328 for displaying the symbols.
Within the display area 328, there are formed five display windows
315 (315A, 315B, 315C, 315D and 315E) visible through their back
surfaces. Further, the symbols drawn on the outer peripheral
surfaces of the reels 314A, 314B, 314C, 314D and 314E are displayed
on a three-by-three basis, through the display windows 315A, 315B,
315C, 315D and 315E.
[0322] Although the present invention has been described with
reference to embodiments thereof, these embodiments merely
illustrate concrete examples, not restrict the present invention.
The concrete structures of respective means and the like can be
designed and changed as required. Furthermore, there have been
merely described most preferable effects of the present invention,
