Description
CROSS-REFERENCE TO THE RELATED APPLICATION(S)
[0001] The present application is based upon and claims priority
from prior Japanese Patent Application No. 2005-252307, filed on
Aug. 31, 2005, the entire contents of which are incorporated herein
by reference.
TECHNICAL FIELD
[0002] The present invention relates to a gaming machine for
enabling a player to play a variable display game according to
variable display and stop display of a plurality of symbols.
BACKGROUND
[0003] Hitherto, various gaming machines such as a slot machine
have been known as a gaming machine for paying out game medium used
with a game, such as medals or coins, (which will be hereinafter
simply referred to as "coins").
[0004] For example, some slot machines are designed for allowing a
player to play a variable display game (also called slot game) by
variably displaying a plurality of symbols on a plurality of rows
using mechanical reels each with a plurality of symbols drawn on
the outer peripheral surface thereof or displaying reel images on
display unit such as a liquid crystal display for producing
variable display and stop display. With any of the slot machines,
if the player performs predetermined operation, the reels rotate or
scroll and when the reels stop, whether or not the player wins the
variable display game and the winning state if the player wins the
game are determined according to the combination of the symbols on
the reels on a predetermined activated pay line (pay line)
(hereinafter, the combination of the symbols will be referred to as
the symbol combination). An exemplary configuration of the
above-described slot machine is disclosed in JP-A-2005-073829. An
exemplary pachinko gaming machine that is applicable to the
above-described slot machine is disclosed in JP-A-7-096072.
[0005] The slot machine in the related art described above has a
dispersed arrangement configuration where high award symbols
indicating the highest award among the symbols on the reels (for
example, "7," etc.; as the symbols are complete on the pay line, a
large profit (award) is given to the player) are dispersed
appropriately in the rotation direction of each reel (different
symbols are arranged between the high award symbols). This is
intended mainly for distributing the expectation of the player on
award gain over the reels as a win and a loss are made to appear in
a mixed manner and a high award symbol indicating that the player
gains a large award occurs properly.
[0006] However, if each reels has the dispersed arrangement
configuration, as a high award symbol is displayed only a little
deviating from the activated pay line, another symbol is displayed
and the player recognizes that a high award is impossible. If this
is repeated, later it is made impossible for the player to play a
game with a wish to gain a high award.
[0007] In this regard, it is also possible to enlarge a win symbol
as with the gaming machine in the document JP-7-096072, for
example. However, although the player considers that seemingly it
becomes easy to win the game as the win symbol is displayed
largely, since the win symbols are arranged in a dispersed manner,
the situation in which the player cannot gain the expected high
award when the win symbol is displayed deviating from the activated
pay line remains unchanged, and the problem is not solved.
[0008] On the other hand, the symbols displayed on the reel include
a symbol called blank symbol (a symbol implemented as a blank
display part with no displayed symbol, meaning a lose (blank), and
giving no profit). This blank symbol generally has no special role
except that it gives the player an at-a-glance picture of a lose
(blank). In this regard, the document JP-2005-073829 discloses a
gaming machine for assigning the blank symbol a role as a trigger
to make a transition to a bonus game. If the blank symbol thus has
the role as a trigger to make a transition to a bonus game, the
player can have an indirect expectation on award gain such that the
player may gain an award if a transition is made to a bonus game.
Nevertheless, the player cannot always gain his or her expected
high award.
SUMMARY
[0009] One of objects of the present invention to provide a gaming
machine that enables a player to play a variable display game with
a continuous wish to gain a high award and enhance the amusement of
the variable display game.

including: controlling the image display device to perform variable
display for variably displaying a plurality of symbols in a
predetermined sequence in the symbol display area when the start
command is input through the operation unit; determining a stop
state of the symbol by determining a symbol from among the
plurality of symbols to be displayed stopped on a pay line that is
configured for determining a win of the game; controlling the image
display device to perform stop display of the determined symbol on
the pay line in the stop state; and performing a payout of an award
to the player in accordance with the stop state. The predetermined
sequence includes a three-symbols-continuous arrangement in which a
first highest award symbol indicating a most highest award among
the plurality of symbols, and a second highest award symbol
indicating a second highest award among the plurality of symbols,

DETAILED DESCRIPTION
[0032] Embodiments of the invention will be discussed with
reference to the accompanying drawings. In the following
description, the identical elements or the elements having the
identical functions are denoted by the same reference numerals and
will not be discussed again.
First Embodiment
[0033] In the description of a first embodiment, a slot machine 1
is taken as an example as the case where the invention is applied
to a gaming machine having a reel unit 5 as a variable display
means (image display device) in the invention for variably
displaying a plurality of symbols by mechanical reels. The slot
machine 1 requires that the play input a coin to start a game.
General configuration of slot machine
[0034] To begin with, the general configuration of the slot machine
1 according to a first embodiment will be discussed with reference
to FIG. 1. FIG. 1 is a perspective view to show the general
configuration of the slot machine according to the embodiment.
[0035] The slot machine 1 has a subsidiary display 3 and a main
display 4 from the top on the front of a cabinet 2. The main
display 4 is arranged almost at the center of the top and bottom of
the cabinet 2 and has the reel unit 5 with three mechanical reels
5L, 5C, and 5R arranged in one horizontal row for rotation in the
cabinet 2 so as to correspond to the main display 4.
[0036] The reels 5L, 5C, and 5R can be visually recognized from the
outside through symbol display areas 21L, 21C, and 21R (described
later) of the main display 4. The reels 5L, 5C, and 5R have each an
outer peripheral surface on which a symbol row having different
types of symbols is drawn, can be rotated so as to variably display
the symbols, and rotate at a constant speed (for example, 80
revolutions/min) although described later in detail.
[0037] One pay line L1 extended horizontally is provided in the
symbol display areas 21L, 21C, and 21R corresponding to the reels
5L, 5C, and 5R, as shown in FIG. 2. Although not shown, a different
pay line may be provided above and below the pay line L1 in
addition to the pay line L1, in which case two pay lines may be
further provided in the slanting direction. When a plurality of pay
lines are provided, it is advisable to change the number of pay
lines in response to the number of input coins. In this case, each
pay line is activated in response to the number of input coins and
operation of a BET switch 10 or 11 described later. The pay line L1
which becomes activated is also called activated pay line or pay
line. For example, if the player inputs one coin into a coin
insertion slot 7 described later, only the pay line L1 at the
center becomes an activated pay line; if the player inputs two
coins, the top and bottom pay lines are added to the pay line L1;
and if the player inputs three coins, all pay lines become
activated pay lines.
[0038] The slot machine 1 is provided with a roughly horizontal
operation panel 6 below the main display 4. The operation panel 6

input a coin to be bet on a game and has an input coin sensor 7a
for outputting a signal indicating coin input (see FIG. 7). The
bill insertion slot 8 is provided for the player to input a bill
and has a bill insertion sensor 8a for outputting a signal
indicating bill insertion (see FIG. 7). The spin switch 9 is
provided for the player to perform operation to start variable
display of symbols with rotation of the reels 5L, 5C, and 5R in the
symbol display areas 21L, 21C, and 21R, namely, to start a slot
game. The 1BET switch 10 is provided for the player to make setting
of bet of one coin by operating the switch once. The maximum BET
switch 11 is provided for the player to make setting of bet of the
maximum number of coins that can be bet on one game by operating
the switch once.
[0040] Further, the slot machine 1 is provided with speakers 12L
and 12R, a coin payout opening 13 positioned so as to be sandwiched
between the speakers 12L and 12R, and a coin receiving tray 14 at
the bottom of the cabinet 2.

[0041] The main display 4 has the symbol display areas 21L, 21C,
and 21R, window frame display areas 22L, 22C, and 22R, and an
effect display area 4a, as shown in FIG. 2. The display of the main
display 4 changes in response to the variable display state and the
stop state of each of the reels 5L, 5C, and 5R and the operation of
the slot machine 1.
[0042] The symbol display areas 21L, 21C, and 21R are areas
provided corresponding to the reels 5L, 5C, and 5R respectively for
displaying the symbols drawn on the reels 5L, 5C, and 5R to allow
the player to visually recognize the drawn symbols. Transparent

5C, and 5R being scrolled and the symbols drawn thereon when the
reels 5L, 5C, and 5R are rotating and stop is produced in the
symbol display areas 21L, 21C, and 21R.
[0043] The window frame display areas 22L, 22C, and 22R are
provided so as to surround the corresponding symbol display areas
21L, 21C, and 21R and function as display windows of the symbols
drawn on the reels 5L, 5C, and 5R.
[0044] Effects to increase player's interest and information for
the player to advantageously advance a game are displayed in the
effect display area 4a.
[0045] The display of the subsidiary display 3 changes in response
to the operation of the slot machine 1.
Configuration of reels
[0046] Next, the configuration of the reels 5L, 5C, and 5R will be
discussed with reference to FIGS. 3 and 4. FIG. 3 is a front view
to show the configuration of the reels. FIG. 4 is a perspective
view to show one of the reels shown in FIG. 3.
[0047] The reels 5L, 5C, and 5R are arranged in one horizontal row
as shown in FIG. 3 and can rotate. The reel 5L has two annular
frames of the same shape 23 and 23 are arranged with a
predetermined spacing and has a cylindrical frame having the
annular frames 23 and 23 joined by a plurality of joint members 25,
as shown in FIG. 4. The reel 5L also has a transfer member 26 for
transferring the drive force of a stepping motor M1 (see FIG. 7)
arranged in the center of the cylindrical frame to the annular
frames 23 and 23, and a reel sheet (not shown) with a plurality of
symbols drawn thereon is put on a side of the reel 5L so as to
cover the joint members 25. The reel 5C, 5R has the same
configuration as the reel 5L.
[0048] On the reel sheet, symbol rows R1 to R3 with a plurality of
symbols corresponding to a stop table 90 shown in FIG. 12 arranged
in the rotation direction of the reels are drawn corresponding to
the reels 5L, 5C, and 5R. FIG. 12 shows the contents of the stop
table 90 described later. The symbol rows R1 to R3 drawn on the
reels 5L, 5C, and 5R will be discussed with reference to FIG. 12.
The symbol rows R1 to R3 are drawn on the reels 5L, 5C, and 5R. A
plurality of symbols are drawn on the symbol rows R1 to R3 in the
order as the symbols are drawn in columns of R1 to R3 in FIG. 12.
Each of the symbol rows R1 to R3 contains a high award symbol W1
(first highest award symbol) indicating that the largest award in
the slot machine 1 according to the embodiment (for example, paying
out 1199 coins) is given to the player as the symbols W1 are
stop-displayed completely on the activated pay line L1, a high
award symbol W2 (second highest award symbol) indicating that a
large award smaller than and next to the high award symbol W1 (for
example, paying out 300 coins) is given to the player when the
symbols W2 are stop-displayed completely on the activated pay line
L1, and a blank symbol W3 indicating that no award is given if the
symbols W3 are stop-displayed on the activated pay line L1. Each of
the symbol rows R1 to R3 has a three-symbols-continuous arrangement
configuration wherein the high award symbol W1 and the high award
symbol W2 are arranged adjacent to the blank symbol. If both the
high award symbol W1 and the high award symbol W2 are
stop-displayed on the activated pay line L1, a large award smaller
than and next to the high award symbol W2 (for example, paying out
200 coins) is given to the player.
[0049] The high award symbol W1 is a symbol containing a digit of
"7" as a pattern and a flame pattern W1 drawn behind the digit and
is drawn largely with a size of about three times the size of any
other symbol. In the high award symbol W1, the upper end and the
lower end of the flame pattern W1 are drawn so as to a little
project to the adjacent blank symbols W3. The high award symbol W2
is a symbol with a digit of "7" drawn as a pattern. Further, the
blank symbol W3 is a symbol implemented as a blank display part
with nothing displayed as a pattern. When the high award symbol W1
is stop-displayed on the pay line L1, the high award symbol W1 is
larger than any other symbol and thus only the high award symbol W1
is displayed as shown in FIG. 2. In contrast, when any other symbol
than the high award symbol W1 is stop-displayed, three symbols are
displayed in the longitudinal arrangement in the symbol display
area 21R, for example, as shown in FIG. 14 (the same also applies
to the symbol display areas 21L and 21C).
Description of liquid crystal display
[0050] Next, a liquid crystal display 31 implementing the main
display 4 will be discussed with reference to FIGS. 5 and 6. FIG. 5
is a perspective view to show the schematic configuration of the
liquid crystal display viewed from the rear of the cabinet. FIG. 6
is an exploded perspective view of a part of the liquid crystal
display.
[0051] The liquid crystal display 31 is provided in front of the
reels 5L, 5C, and 5R with a predetermined spacing from the reels
5L, 5C, and 5R across the reels 5L, 5C, and 5R. The liquid crystal
display 31 has protective glass 32 and a display plate 33 having a
translucent property, a liquid crystal panel 34, a light guide
plate 35, a reflecting film 36, fluorescent lamps 37a, 37b, 38a,
and 38b as white light sources, and a flexible board (not shown)
connected to a terminal section of the liquid crystal panel 34 and
made of a table carrier package (TCP) on which a drive IC of the
liquid crystal panel 34 is installed.
[0052] The liquid crystal panel 34 is formed with the symbol
display areas 21L, 21C, and 21R. The liquid crystal panel 34
enables the player to visually recognize the symbols drawn on the
reels 5L, 5C, and 5R through the symbol display areas 21L, 21C, and
21R and play a variable display game by visually recognizing
variable display and stop display of the reels 5L, 5C, and 5R. The
light guide plate 35 has transparency and is placed on the rear of
the liquid crystal panel 34 for guiding light from the fluorescent
lamps 37a and 37b to the liquid crystal panel 34.
[0053] The reflecting film 36 is provided for reflecting light
guided to the light guide plate 35 toward the surface of the light
guide plate 35. The reflecting film 36 has reflecting area 36A and
non-reflecting areas 36BL, 36BC, and 36BR. The reflecting area 36A
reflects incident light and operates as illumination means mainly
for the areas corresponding to the window frame display areas 22L,
22C, and 22R and the effect display area 4a of the liquid crystal
panel 34. The non-reflecting areas 36BL, 36BC, and 36BR are formed
corresponding to the symbol display areas 21L, 21C, and 21R and are
placed ahead of stop symbols stop-displayed when the reels 5L, 5C,
and 5R stop rotation.
[0054] The fluorescent lamps 37a and 37b generate light guided to
the light guide plate 35 and operates as illumination means mainly
for the areas corresponding to the window frame display areas 22L,
22C, and 22R and the effect display area 4a of the liquid crystal
panel 34. The fluorescent lamps 38a and 38b operate as illumination
means for the symbols arranged on the reels 5L, 5C, and 5R and
illumination means for the areas of the reflecting film 36
corresponding to the symbol display areas 21L, 21C, and 21R.
Internal configuration of slot machine
[0055] FIG. 7 is a block diagram of the slot machine 1 shown
centering on the internal configuration. The slot machine 1 has
components centering on a control board 41. The control board 41
has a microcomputer 42, a random number generator 43, a sampling
circuit 44, a clock pulse generation circuit 45, and a frequency
divider 46.
[0056] The microcomputer 42 has a CPU (Central Processing Unit) 47,
RAM (Random Access Memory) 48, and ROM (Read-Only Memory) 49. The
CPU 47 operates as symbol determination means and symbol display
control means in the invention in accordance with programs stored
in the ROM 49 and also inputs/outputs signals from/to other
components through an I/O port 50 and controls the whole operation
of the slot machine 1. The RAM 48 stores data and programs used
when the CPU 47 operates. That is, for example, the RAM 48
temporarily holds the random number sampled by the sampling circuit
44 described later after a game is started and also stores the code
numbers of the reels 5L, 5C, and 5R, etc. The ROM 49 stores the
programs executed by the CPU 47 and permanent data.
[0057] The random number generator 43 operates in accordance with a
command of the CPU 47 and generates random numbers in a given
range. The sampling circuit 44 extracts an arbitrary random number
from among the random numbers generated by the random number
generator 43 in accordance with a command of the CPU 47 and inputs
the extracted random number to the CPU 47. The clock pulse
generation circuit 45 generate a reference clock to operate the CPU
47, and the frequency divider 46 inputs a signal provided by
dividing the reference clock in a given period to the CPU 47.
[0058] The control board 41 has a hopper drive circuit 51, a payout
completion signal circuit 52, a sound control circuit 53, and an
image control circuit 54.
[0059] The hopper drive circuit 51 drives a hopper 55 under the
control of the CPU 47. The hopper 55 performs the operation to pay
out coins and pays out coins through the coin payout opening
13.
[0060] The payout completion signal circuit 52 inputs
number-of-coins data from a connected coin detection section 56 and
when the number of coins reaches the setup value of the number of
coins, the payout completion signal circuit 52 inputs a
notification signal of coin payout completion to the CPU 47. The
coin detection section 56 measures the number of coins paid out by
the hopper 55 and inputs the measured number-of-coins data to the
payout completion signal circuit 52.
[0061] The sound control circuit 53 inputs a command from the CPU
47 and controls a sound signal to output a sound from the speakers
12L and 12R for causing the speakers 12L and 12R to output a sound.
Accordingly, for example, a sound for augmenting a game at an
appropriate timing after the game starts is output from the
speakers 12L and 12R.
[0062] The image control circuit 54 controls image display of the
subsidiary display 3 and the main display 4. The image control
circuit 54 has an image control CPU 54a, work RAM 54b, program ROM
54c, image ROM 54d, video RAM 54e, and a VDP (Video Display
Processor) 54f as shown in FIG. 8.
[0063] The image control CPU 54a determines the images to be
displayed on the subsidiary display 3 and the main display 4 in
accordance with an image control program (concerning display on the
subsidiary display 3 and the main display 4) previously stored in
the program ROM 54c based on a parameter set in the microcomputer
42. The work RAM 54b is implemented as temporary storage means when
the image control CPU 54a executes the image control program. The
program ROM 54c stores the image control program, various selection
tables, etc. The image ROM 54d stores dot data for forming images.
The video RAM 54e is implemented as temporary storage means when an
image is formed by the VDP 54f. The VDP 54f has control RAM 54g and
forms images responsive to the display of the subsidiary display 3
and the main display 4 determined by the image control CPU 54a and
outputs the formed images to the subsidiary display 3 and the main
display 4 for display.
[0064] A reel drive unit 57 has a reel position detection circuit
59 for detecting the positions of the reels 5L, 5C, and 5R and a
motor drive circuit 60 for inputting a drive signal to motors M1,
M2, and M3 for rotating the reels 5L, 5C, and 5R. The drive signal
is input from the motor drive circuit 60, whereby the motors M1,
M2, and M3 are operated for rotating the reels 5L, 5C, and 5R.
[0065] The input coin sensor 7a, the bill insertion slot 8, the
spin switch 9, the 1BET switch 10, and the maximum BET switch 11
are connected to the control board 41, so that signals are input
from the components to the control board 41.
Operation of slot machine
[0066] Next, the operation of the described slot machine 1 will be
discussed with reference to flowcharts of FIGS. 9 to 11. FIG. 9 is
a flowchart to show an operation procedure of main processing from
the game start to end of the slot machine according to the
embodiment. FIG. 10 is a flowchart to show an operation procedure
of lottery processing. FIG. 11 is a flowchart to show an operation
procedure of base game processing. In FIGS. 9 to 11, a step is
abbreviated as S.
[0067] In the slot machine 1, when the main processing shown in
FIG. 9 is started, start acceptance processing, lottery processing,
and base game processing are performed in order at steps 1 to 3.
The blocks will be discussed below in detail:
[0068] To begin with, at step 1, start acceptance processing is
performed. That is, the player inputs any desired number of coins
into the coin insertion slot 7 and when credit remains, the player
operates the 1BET switch 10 or the maximum BET switch 11.
Subsequently, the player operates the spin switch 9 (hereinafter,
the operation will be referred to as "start operation"). As the
start operation is performed, a start signal is input from the spin
switch 9 to the CPU 47.
[0069] Next, at step 2, lottery processing is performed. When the
lottery processing is performed, the process goes to step 11 shown
in FIG. 10 and the CPU 47 performs symbol determination processing.
In this symbol determination processing, the CPU 47 operates as
symbol determination means in response to input of the start signal
and determines the symbols to be stop-displayed (stop symbols) on a
pay line L1 for the reels 5L, 5C, and 5R. During the lottery
processing, the CPU 47 may instruct the image control circuit 54 to
produce game effect display on the subsidiary display 3 and the
main display 4.
[0070] In the lottery processing, when the CPU 47 detects start
operation of the player according to the start signal from the spin
switch 9, upon reception of the detection (namely, with the start
of a slot game as a trigger), the CPU 47 instructs the random
number generator 43 to generate random numbers in a given range (in
the embodiment, 0 to 254). The CPU 47 instructs the sampling
circuit 44 to extract an arbitrary random number from among the
random numbers generated by the random number generator 43. When a
random number is extracted by the sampling circuit 44, the CPU 47
sets the random number as a search key, references a stop symbol
determination table (a table storing symbol code numbers and random
numbers in association with each other) 91 shown in FIG. 13, stored
in the ROM 49, and acquires the symbol code number corresponding to
the search key (random number) (the random numbers only in a
partial range are shown in FIG. 13). The stop symbol determination
table 91 has a symbol code number area 91b for storing the symbol
code numbers and a random number area 91a for storing the random
numbers ranging from 0 to 254 associated with the symbol code
numbers, as shown in FIG. 13. That is, the probability that one
symbol will be stop-displayed as a stop symbol on the pay line L1
is determined by the random number range associated with the symbol
code number.
[0071] Next, the acquired code number is set as a search key, the
stop table 90 shown in FIG. 12 is referenced, and a search is made
for the symbols to be stop-displayed (stop symbols) on the pay line
L1 when the reels 5L, 5C, and 5R stop. The stop table 90 is a table
having a code number area 90a for storing the symbol code numbers
and a symbol area 90b for storing the symbols corresponding to each
code number, as shown in FIG. 12, and with the code number set as a
search key, the code number area can be searched for the
corresponding symbols for each of the reels 5L, 5C, and 5R. The
symbols corresponding to the symbol rows R1 to R3 drawn on the reel
sheets put on the reels 5L, 5C, and 5R are registered in the symbol
area 90b in a one-to-one correspondence with the code numbers. For
example, C1 in FIG. 12 shows a symbol combination made up of
symbols when the acquired code numbers are all "0" relative to the
reels 5L, 5C, and 5R.
[0072] In the slot machine 1, random number lottery and searching
the stop symbol determination table 91 and the stop table 90 are
executed three times in total for the reels 5L, 5C, and 5R. This
means that the tables 90 and 91 are searched as many times as the
number of the reels. When the stop symbols are determined relative
to the reels 5L, 5C, and 5R, the reel stop positions to stop the
symbols on the pay line L1 are determined.
[0073] When the reel stop positions are determined, the process
goes to step 12 (winning combination determination processing) The
CPU 47 references a winning combination determination table (not
shown) (a table in which winning symbol combinations and
non-winning symbol combinations are registered so that they can be
distinguished from each other in association with each code number
combination (which will be hereinafter referred to as "code number
pattern") stored in the ROM 49, and determines a winning
combination or a non-winning combination using the code number
pattern. Subsequently, the CPU 47 references a state table (not
shown) stored in the ROM 49 and determines the winning state (also
called "combination") when a winning combination occurs. The state
table is provided for determining the winning state and the award
responsive to each winning state is registered in the state
table.
[0074] Next, when base game processing is started at step 3, a slot
game is executed. At this time, the process goes to step 21 shown
in FIG. 11 and rotation processing is executed. That is, the CPU 47
instructs the motor drive circuit 60 to operate the motors M1, M2,
and M3. Then, the reels 5L, 5C, and 5R rotate at a constant speed
for a given time. Next, the process goes to step 22 and stop
control processing is performed. The CPU 47 operates as symbol
display control means of the invention and instructs the motor
drive circuit 60 to stop the reels 5L, 5C, and 5R in this order (in
the order of the left, the center, and the right) so that the stop
symbols determined in the symbol determination processing at step
11 appear and are stop-displayed on the pay line L1. Since the slot
machine 1 has the three reels of the reels 5L, 5C, and 5R, stop
position determination of each of the reels 5L, 5C, and 5R
(determination of the symbol to be stopped on the pay line L1) is
executed three times. The process goes to step 23 (payout
processing). If it is determined in the winning combination
determination processing at step 12 that a winning combination
occurs, the CPU 47 instructs the hopper drive circuit 51 to drive
the hopper 55 for paying out as many coins as the number of coins
of the award responsive to the winning state. Then, the main
processing is terminated.
[0075] As described above, in the embodiment, the symbol rows R1 to
R3 containing the high award symbols W1 and W2 and the blank symbol
W3 are drawn on the reel sheets put on the reels 5L, 5C, and 5R and
have each the three-symbols-continuous arrangement configuration
wherein the high award symbol W1 and the high award symbol W2 are
arranged adjacent to the blank symbol W3. Thus, if either the high
award symbol W1 or the high award symbol W2 deviates from the
activated pay line, the other is easily stop-displayed on the
activated pay line and if the symbol is not stop-displayed, either
the high award symbol W1 or the high award symbol W2 is arranged
near the activated pay line and is easily visually recognized, for
example, as shown in FIG. 14. Moreover, the blank symbol W3 is
arranged between the high award symbol W1 and the high award symbol
W2, so that when the blank symbol W3 is stop-displayed on the
activated pay line, the player can be made to feel regret at
failing to obtain a high award if the symbol is displayed with one
shift (the blank symbol W3 can be utilized as "regret item" for
making the player feel regret). Consequently, it is made possible
for the player to play a variable display game with the slot
machine 1 with a continuous wish to gain a high award and the
amusement of the variable display game can be enhanced. In the
embodiment, in the high award symbol W1, the upper end and the
lower end of the flame pattern are drawn so as to a little project
to the adjacent blank symbols, so that when the blank symbol W3 is
stop-displayed on the activated pay line, the upper end or the
lower end of the flame of the pattern of the high award symbol W1
is stop-displayed near the activated pay line (see FIG. 14). Thus,
the player can be furthermore made to feel regret at failing to
obtain a high award and can be made to have a further expectation
on the subsequent variable display game.
[0076] In the first embodiment, the high award symbol W1 is
displayed larger than the high award symbol W2, so that the high
award symbol W1 is highlighted. Thus, the player can be made to
recognize that the largest profit is given when the high award
symbols W1 are complete on the activated pay line.
Second Embodiment
[0077] Next, a slot machine 100 according to a second embodiment
will be discussed based on FIGS. 15 and 16. A slot machine 100
according to the second embodiment differs from the slot machine 1
according to the first embodiment described above in that the slot
machine 100 is a video slot machine having no reel unit 5 and has
variable display sections 105L, 105C, and 105R for displaying
variable display images of symbols and enables a player to play a
variable display game with the variable display images displayed on
the variable display sections 105L, 105C, and 105R. A description
will be given centering on the differences and common points will
not be discussed again or will be discussed briefly.
[0078] The slot machine 100 has a main display 4 as an image
display means (image display device) and the main display 4 has the
variable display sections 105L, 105C, and 105R for displaying
variable display images of symbols. A scroll display image as if
symbols moved from the top to the bottom in the order as the
symbols are shown on R1 to R3 of the stop table 90 shown in FIG. 12
(a reel image displayed as if mechanical reels rotated) is
displayed on the variable display sections 105L, 105C, and 105R of
the main display 4. Therefore, also in the slot machine 100
according to the second embodiment, three-symbols-continuous
arrangement display is produced as a high award symbol W1 and a
high award symbol W2 are arranged adjacent to a blank symbol
W3.
[0079] The slot machine 100 has components centering on a control
board 41. The control board 41 has an image control circuit 54 as
one of the components. The image control circuit 54 controls image
display of the main display 4 for displaying various images such as
variable display images of symbols on the main display 4.
[0080] Next, the operation of the slot machine 100 will be
discussed with reference to flowcharts of FIGS. 9 and 17. In the
slot machine 100, when main processing shown in FIG. 9 is started,
start acceptance processing, lottery processing, and base game
processing at steps 1 to 3 are performed as with the slot machine 1
described above. In FIG. 17, a step is abbreviated as S.
[0081] When the base game processing at step 3 is started, the
process goes to step 31 shown in FIG. 17 and scroll processing is
performed. The variable display sections 105L, 105C, and 105R are
displayed on the main display 4 and a CPU 47 instructs the image
control circuit 54 to display a variable display image scrolling a
plurality of symbols on the variable display sections 105L, 105C,
and 105R. Subsequently, the process goes to step 32 and stop
control processing is performed. While the scroll speed is
gradually lowered, stop symbols corresponding to the result of the
lottery processing at step 2 shown in FIG. 9 are displayed on the
variable display sections 105L, 105C, and 105R. Then, at step 33,
when a winning combination occurs, coins responsive to the winning
state are paid out and the base game processing is exited.
[0082] Although the preferred embodiment and its second embodiment
of the invention have been described in detail, it is to be
understood that the invention is not limited to the specific
embodiment or the second embodiment. For example, in the
embodiment, each of the symbol rows R1 to R3 drawn on the reel
sheets put on the reels 5L, 5C, and 5R has the
three-symbols-continuous arrangement configuration wherein the high
award symbol W1 and the high award symbol W2 are arranged adjacent
to the blank symbol W3. However, at least the last stopped specific
symbol row of the symbol rows R1 to R3 may have the
three-symbols-continuous arrangement configuration. More
preferably, at least the symbol row R3 (the right symbol row) put
on the reel 5R arranged at the right toward the slot machine 1 has
the three-symbols-continuous arrangement configuration and other
symbol rows R1 and R2 may have no three-symbols-continuous
arrangement configuration. In the slot machine 1, symbol stop
display is last produced in the symbol row R3 put on the reel 5R
and the player plays a variable display game while paying the most
attention to the symbol stop-displayed in the right symbol row, so
that the function of the three-symbols-continuous arrangement
configuration can be demonstrated more effectively.
[0083] As for the slot machine 100 having the video reels in the
second embodiment, three-symbols-continuous arrangement display may
be produced as the high award symbol W1 and the high award symbol
W2 are arranged adjacent to the blank symbol W3 on at least the
last stop-displayed specific variable display section of the
variable display sections 105L, 105C, and 105R. More preferably,
three-symbols-continuous arrangement display is produced on at
least the variable display sections 105R (the right variable
display section) arranged at the right toward the slot machine 100
and no three-symbols-continuous arrangement display may be produced
on the variable display section 105L or 105C.
[0084] In the embodiment, the slot machine 1 has the reel unit 5
with the reels 5L, 5C, and 5R arranged in one horizontal row, but
may have a reel unit 205 with reels 205T, 205C, and 205B arranged
in one vertical row as shown in FIG. 18. Also in this case, at
least the last stopped specific symbol row of symbol rows drawn on
reel sheets put on the reels 205T, 205C, and 205B may have the
three-symbols-continuous arrangement configuration.
[0085] In the embodiment, when the high award symbols W1 are
stop-displayed completely on the pay line L1, the largest award is
given to the player, but the invention is not limited to the mode.
In addition to giving the largest award when the high award symbols
W1 are stop-displayed completely on the pay line L1, a transition
may be made from the usual gaming state in which the player can
play a usual slot game to a special gaming state such as a free
game wherein the player can play free spin (operation of
automatically rotating the reels 5L, 5C, and 5R without inputting
any new coin, stopping the reels 5L, 5C, and 5R after the
expiration of a given time, and paying out coins in response to the
combination of the stopped symbols) a predetermined number of times
involved in the game, for example. That is, the CPU 47 may
determine whether or not a trigger of a free game is established by
whether or not a code number pattern of stop display of the high
award symbols W1 completely on the pay line L1 occurs after the
base game processing at step 3 shown in FIG. 9 is exited and when
the trigger is established, a transition may be made to the special
gaming state. In so doing, the player can gain a high award as the
high award symbols W1 are complete and can also enjoy a free game,
etc., so that the amusement of the slot machine 1 can be
improved.
[0086] In the embodiments described in detail in the above, the
reel unit 5 in the first embodiment and the main display 4 in the
second embodiment serves as an image display device that has a
symbol display area (the symbol display areas 21L, 21C, and 21R;
and the variable display sections 105L, 105C, and 105R).
[0087] The spin switch 9, the 1BET switch 10, and the maximum BET
switch 11 serves as an operation unit that allows a player to input
operations including a start command to start a game.
[0088] The microcomputer 42 serves as a processor that performs a
game process for providing the player the game by controlling the
image display device to display a progress of the game. As
described in the first and the second embodiments, the
microcomputer 42 performs the game process including: controlling
the image display device to perform variable display for variably
displaying a plurality of symbols in a predetermined sequence in
the symbol display area when the start command is input through the
operation unit; determining a stop state of the symbol by
determining a symbol from among the plurality of symbols to be
displayed stopped on a pay line that is configured for determining
a win of the game; controlling the image display device to perform
stop display of the determined symbol on the pay line in the stop
state; and performing a payout of an award to the player in
accordance with the stop state.
[0089] As described in the first and the second embodiments, the
predetermined sequence includes a three-symbols-continuous
arrangement in which a first highest award symbol indicating a most
highest award among the plurality of symbols, and a second highest
award symbol indicating a second highest award among the plurality
of symbols, are arranged adjacent to a blank symbol implemented as
a blank display part with no symbol displayed thereon.
[0090] The foregoing description of the embodiment has been
presented for purposes of illustration and description. It is not
intended to be exhaustive or to limit the invention to the precise
form disclosed, and modifications and variations are possible in
light of the above teachings or may be acquired from practice of
the invention. The embodiment was chosen and described in order to
explain the principles of the invention and its practical
application to enable those skilled in the art to utilize the
invention in various embodiments and with various modifications as
are suited to the particular use contemplated. It is intended that
the scope of the invention be defined by the claims appended
hereto, and their equivalents.
