[0034] The foregoing summary, as well as the following detailed
description of certain embodiments of the present invention, will
be better understood when read in conjunction with the appended
drawings. For the purpose of illustrating the invention, certain
embodiments are shown in the drawings. It should be understood,
however, that the present invention is not limited to the
arrangements and instrumentality shown in the attached
drawings.
DETAILED DESCRIPTION OF THE INVENTION
[0035] Referring to the drawings, there is shown a gaming system
arranged to implement a game having a suspense mode where display
of at least one reel is made different to at least one other reel
in response to occurrence of a special symbol condition in respect
of one or more win lines played by the player. This can include a
special symbol appearing on a first reel.
[0036] The gaming system can take a number of different forms.
[0037] In a first form, a stand alone gaming machine is provided
wherein all or most components required for implementing the game
are present in a player operable gaming machine.
[0038] In a second form, a distributed architecture is provided
wherein some of the components required for implementing the game
are present in a player operable gaming machine and some of the
components required for implementing the game are located remotely
relative to the gaming machine. For example, a "thick client"
architecture may be used wherein part of the game is executed on a
player operable gaming machine and part of the game is executed
remotely, such as by a gaming server; or a "thin client"
architecture may be used wherein most of the game is executed
remotely such as by a gaming server and a player operable gaming
machine is used only to display audible and/or visible gaming
information to the player and receive gaming inputs from the
player.
[0039] However, it will be understood that other arrangements are
envisaged. For example, an architecture may be provided wherein a
gaming machine is networked to a gaming server and the respective
functions of the gaming machine and the gaming server are
selectively modifiable. For example, the gaming system may operate
in stand alone gaming machine mode, "thick client" mode or "thin
client" mode depending on the game being played, operating
conditions, and so on. Other variations will be apparent to persons
skilled in the art.
[0040] A gaming system in the form of a stand alone gaming machine
10 according to an embodiment is illustrated in FIG. 1. The gaming
machine 10 includes a console 12 having a display 14 on which is
displayed representations of a game 16 that can be played by a
player. A mid-trim 20 of the gaming machine 10 houses a bank of
buttons 22 for enabling a player to interact with the gaming
machine, in particular during gameplay. The mid-trim 20 also houses
a credit input mechanism 24 which in this example includes a coin
input chute 24A and a bill collector 24B. Other credit input
mechanisms may also be employed, for example, a card reader for
reading a smart card, debit card or credit card. A reading device
may also be provided for the purpose of reading a player tracking
device, for example as part of a loyalty program. The player
tracking device may be in the form of a card, flash drive or any
other portable storage medium capable of being read by the reading
device.
[0041] A top box 26 may carry artwork 28, including for example pay
tables and details of bonus awards and other information or images
relating to the game. Further artwork and/or information may be
provided on a front panel 29 of the console 12. A coin tray 30 is
mounted beneath the front panel 29 for dispensing cash payouts from
the gaming machine 10.
[0042] The display 14 shown in FIG. 1 is in the form of a video
display unit, particularly a cathode ray tube screen device.
Alternatively, the display 14 may be a liquid crystal display,
plasma screen, any other suitable video display unit, or the
visible portion of an electromechanical device. The top box 26 may
also include a display, for example a video display unit, which may
be of the same type as the display 14, or of a different type.
[0043] FIG. 2 shows a block diagram of operative components of a
typical gaming machine which may be the same as or different to the
gaming machine of FIG. 1 according to an embodiment.
[0044] The gaming machine 100 includes a game controller 101 having
a processor 102. Instructions and data to control operation of the
processor 102 are stored in a memory 103, which is in data
communication with the processor 102. Typically, the gaming machine
100 will include both volatile and non-volatile memory and more
than one of each type of memory, with such memories being
collectively represented by the memory 103.
[0045] The gaming machine has hardware meters 104 for purposes
including ensuring regulatory compliance and monitoring player
credit, an input/output (I/O) interface 105 for communicating with
peripheral devices of the gaming machine 100. The input/output
interface 105 and/or the peripheral devices may be intelligent
devices with their own memory for storing associated instructions
and data for use with the input/output interface or the peripheral
devices. A random number generator module 113 generates random
numbers for use by the processor 102.
[0046] In the example shown in FIG. 2, a player interface 120
includes peripheral devices that communicate with the game
controller 101 comprise one or more displays 106, a touch screen
107, a card and/or ticket reader 108, a printer 109, a bill
acceptor and/or coin input mechanism 110 and a coin output
mechanism 111. Additional hardware may be included as part of the
gaming machine 100, or hardware may be omitted as required for the
specific implementation.
[0047] In addition, the gaming machine 100 may include a
communications interface, for example a network card 112. The
network card may, for example, send status information, accounting
information or other information to a central controller, server or
database and receive data or commands from the central controller,
server or database.
[0048] FIG. 3 shows a block diagram of the main components of an
exemplary memory 103 according to an embodiment. The memory 103
includes RAM 103A, EPROM 103B and a mass storage device 103C. The
RAM 103A typically temporarily holds program files for execution by
the processor 102 and related data. The EPROM 103B may be a boot
ROM device and/or may contain some system or game related code. The
mass storage device 103C is typically used to store game programs,
the integrity of which may be verified and/or authenticated by the
processor 102 using protected code from the EPROM 103B or
elsewhere.
[0049] It is also possible for the operative components of the
gaming machine 100 to be distributed, for example input/output
devices 106,107,108,109,110,111 to be provided remotely from the
game controller 101.
[0050] FIG. 4 shows a gaming system 200 in accordance with an
embodiment. The gaming system 200 includes a network 201, which for
example may be an Ethernet network. Gaming machines 202, shown
arranged in three banks 203 of two gaming machines 202 in FIG. 5,
are connected to the network 201. The gaming machines 202 provide a
player operable interface and may be the same as the gaming
machines 10,100 shown in FIGS. 1 and 2, or may have simplified
functionality depending on the requirements for implementing game
play. While banks 203 of two gaming machines are illustrated in
FIG. 4, banks of one, three or more gaming machines are also
envisaged.
[0051] One or more displays 204 may also be connected to the
network 201. The displays 204 may, for example, be associated with
one or more banks 203 of gaming machines. The displays 204 may be
used to display representations associated with game play on the
gaming machines 202, and/or used to display other representations,
for example promotional or informational material.
[0052] In a thick client embodiment, game server 205 implements
part of the game played by a player using a gaming machine 202 and
the gaming machine 202 implements part of the game. With this
embodiment, as both the game server and the gaming device implement
part of the game, they collectively provide a game controller. A
database management server 206 may manage storage of game programs
and associated data for downloading or access by the gaming devices
202 in a database 206A. Typically, if the gaming system enables
players to participate in a Jackpot game, a Jackpot server 207 will
be provided to monitor and carry out the Jackpot game.
[0053] In a thin client embodiment, game server 205 implements most
or all of the game played by a player using a gaming machine 202
and the gaming machine 202 essentially provides only the player
interface. With this embodiment, the game server 205 provides the
game controller. The gaming machine will receive player
instructions, pass these to the game server which will process them
and return game play outcomes to the gaming machine for display. In
a thin client embodiment, the gaming machines could be computer
terminals, e.g. PCs running software that provides a player
interface operable using standard computer input and output
components.
[0054] Servers are also typically provided to assist in the
administration of the gaming network 200, including for example a
gaming floor management server 208, and a licensing server 209 to
monitor the use of licenses relating to particular games. An
administrator terminal 210 is provided to allow an administrator to
run the network 201 and the devices connected to the network.
[0055] The gaming network 200 may communicate with other gaming
systems, other local networks, for example a corporate network,
and/or a wide area network such as the Internet, for example
through a firewall 211.
[0056] In certain embodiments, functionality at the server side of
the network may be distributed over a plurality of different
computers. For example, elements may be run as a single "engine" on
one server or a separate server may be provided. For example, the
game server 205 could run a random generator engine. Alternatively,
a separate random number generator server could be provided.
Further, in certain embodiments, a plurality of games servers could
be provided to run different games or a single game server may run
a plurality of different games as required by the terminals.
[0057] Gaming systems for implementing games that involve a display
of spinning reels as part of the display of the outcome of a game
have either a video display or a mechanical display, these later
machines most usually being "stepper" machines which have a
separate motor for each reel.
[0058] The game controllers of such gaming machines have a stop
determining function that determines the stop position for each
reel. For example, if there are five reels, each having twenty
symbols, the stop determining function might determine that the
stop positions are positions: 3, 13, 7, 9 and 17. The spinning of
the reels is then controlled so that each symbol comes to a stop in
the same row, typically a predetermined row in a "window" visible
to the player on the display that which corresponds to a player
playing a single win line. When a reel stops, the symbols will be
in one of a plurality of possible symbol positions for that reel
relative to the stop position.
[0059] Embodiments of the present invention relate to gaming
systems that allow a player to select how many win lines of a
plurality of win lines they will play in each game--i.e. a minimum
of one win line up to the maximum number of win lines allowed by
the game. Each win line is formed by a set of symbol positions
consisting of one symbol position from each reel. That is, a
predetermined symbol position of each reel is assigned to a win
line. The symbol positions that constitute each of the win lines
are usually advertised to the player by markings on the display or
diagrams showing the symbol positions that correspond to each win
line. Some of the win lines will be horizontal or diagonal lines
but others may be non-linear combinations of symbols. Typically,
the win lines will be constituted by symbol positions in the
visible window.
[0060] FIG. 6 shows the main functional components of a gaming
system 600 of an embodiment. The game controller 605 includes a
suspense mode controller 650 that controls whether the gaming
system will enter a "suspense mode" where display of the spinning
of at least one reel is controlled to be different to the spinning
of another reel to thereby enhance game play. The suspense mode
controller 650 determines which win lines the player has selected
to play and then determines whether a suspense condition is met in
relation to the player selected win lines. Depending on the nature
of the suspense condition, it may be met in relation to a single
win line or by a combination of win lines as described below.
Certain embodiments relate to cases where the suspense condition is
either a special symbol condition or, where there are plural
suspense conditions, at least one of which is a special symbol
condition. A "special symbol" is a symbol that has a particular
impact on the game, for example, a wild symbol that can be
substituted for any other symbol or a symbol that has a doubling
effect on all prizes. One example of a special symbol condition may
be that the special symbol appears on a win line after one of the
first two reels spins to a stop.
[0061] In order to play the game, the player enters credits using a
credit mechanism in a conventional manner. The player then operates
the player interface to specify the amount they want to bet per win
line and the number of win lines they wish to play by operating a
win line selector 660. That is, the player may play one or a
plurality of win lines up to the maximum number of win lines
available for the game. For example if there are a maximum of three
win lines, the player may play one, two or three win lines. A stop
determiner 620, obtains random numbers from the random number
generator 610 and uses them to determine the stop position of each
of the reels. As described above, the stop positions will specify
which symbols of each reel will correspond to win lines.
[0062] The stop positions are supplied by the stop determiner 620
to a reel controller 630 which controls the display of the spinning
of individual reels to stop positions on display 640. In normal
operation of a video display this will result in a display where
the reel is animated so that initially the reel is imperceptible to
give the impression of spinning and then the symbols become
perceptible so that a certain number of symbols (for example 6
symbols) can be viewed by the player before the reel reaches the
stop position. In a mechanical display, the reel needs to be moved
from its current stop position (from the previous game) to the new
stop position. The duration and speed of spinning during a normal
display of spinning will either be the same for each reel or within
a normal range.
[0063] As described in further detail below the reel controller 630
may also receive an adjustment instruction from suspense mode
controller 650 which is used by the reel controller 630 to control
the display of spinning of the reels to make display of at least
one reel different. The stop positions are also provided to a game
outcome processor 670. The game outcome processor 670 processes the
stop positions in accordance with the game rules 675 and the
selected win lines to determine whether the player has won. The
game outcome processor 670 alters meters 680 based on the game
outcome and causes the prize outcome to be displayed on the display
640 once the reel controller 630 has caused the display 640 to
display all reels spinning to a stop position.
[0064] The suspense mode controller 650 determines whether one or
more adjustment instructions are to be supplied to the reel
controller 630 during a game. The adjustment instruction causes the
reel controller 630 to alter the display of spinning of at least
one reel.
[0065] The suspense condition determiner 654 processes the win
lines that are selected by win line selector 660 in conjunction
with the reel stop positions produced by the stop determiner 620,
to thereby determine the symbols that will appear on win lines that
a player has selected.
[0066] This allows the suspense condition determiner 654 to
determine whether a special symbol condition or another suspense
condition will be met such as a predetermined game outcome
appearing possible after a certain number of reels reach their stop
positions. In an embodiment, the only suspense condition is a
special symbol condition. By way of example, a special symbol
condition may be that a special symbol appears on a specific reel
or that a special symbol in combination with the other symbols
corresponds to an initial portion of a winning symbol combination.
Special symbol conditions 653a are typically a subset of suspense
conditions 653. For example, the suspense condition determiner 654
may run a specific sub routines to monitor for each suspense
condition being monitored. For example, a sub-routine to count a
number of symbols of a certain type. If a suspense condition is
satisfied, adjuster 656 determines an adjustment and supplies it to
the reel controller 630. If in a specific embodiment only one type
of adjustment is applied, the adjuster can send an adjustment
instruction to the reel controller 630 which is configured to make
the relevant adjustment. Depending on the embodiment the adjuster
656 may calculate the adjustment based on a predetermined formula
or obtain the relevant adjustment from adjustment data 657 and send
it as an adjustment instruction specifying the adjustment to reel
controller 630 for implementation.
[0067] Referring to the flow chart in FIG. 7 of an embodiment, at
step 710 a new game is started. At step 720 a player operates the
win line selector to select a number of lines to play. At step 730
the stop determiner determines the stops and supplies data
specifying these to the reel controller and the possible outcome
processor. At step 740 the suspense conditioner determines whether
a special symbol condition or other suspense condition that is
monitored exists and hence whether the adjuster should generate
adjustment data based on the possible outcomes. If no suspense
conditions are met the process stops 750 for this game. If one or
more suspense conditions are met, at step 760 the adjuster
determines an adjustment and supplies it to the reel controller as
adjustment data. At step 770 the reel controller controls displays
of spinning of each reel to the stop position based on the stops
and adjustments. At step 780 the game ends.
[0068] Suspense Conditions
[0069] Other suspense conditions may be based on a predetermined
game outcome being possible after one or more reels are spun to a
stop position. The game outcome may be an entry in a pay table for
the game or may be a value derived from the pay table such as a
prize threshold. The number of reels that are required to have
reached the stop position may form part of the suspense condition.
If a prize is awarded for five symbols of the same type, it may be
appropriate to trigger a suspense condition after two or three
symbols of the same type have been spun to a stop on the same win
line.
[0070] A suspense condition may be based on the predetermined game
outcome being that a prize is above a particular threshold value.
For example, the suspense condition determiner 654 may determine a
number of possible game outcomes in the pay table appear possible
after three of the reels have spun to a stop and based on the
associated prizes determines whether any of the prizes are above a
preset threshold.
[0071] A suspense condition may be based on a combination of two or
more factors, for example the size of the prize corresponding to
the outcome that appears possible and how likely it appears after a
reel has spun to a stop that the player will win the prize; that
is, based on the probability of the outcome occurring.
[0072] By way of specific example, in one game a prize may be
awarded for five aces and may be the maximum prize for that game. A
lesser prize may be awarded for four aces. A suspense condition may
be set in relation to the five ace prize, so that if the first
three reels each have aces on a win line, a suspense mode may be
triggered. That is, the five ace prize appears to be possible after
three reels and is judged to be sufficiently likely once the first
three reels have aces. If the first three reels are two aces and a
king, suspense mode is not entered into and suspense mode will only
be entered into if three of the first four reels are aces because
it is not until the fourth reel that it is deemed that it will
appear sufficiently likely that they will win the four ace prize
and hence it is deemed appropriate to enter the suspense mode in
view of the size of the prize. In this example, for a higher prize
a relatively lower likelihood is sufficient to trigger a suspense
mode.
[0073] The above suspense conditions relate to a symbol combination
on a single win line, however the suspense condition may based on
multiple win lines. For example, in one embodiment a suspense mode
may only be entered into if a game outcome from the pay table
appears possible in relation to two or more win lines played by a
player. That is, a subset of all winning outcomes specified in the
pay table may be sufficient to initiate a suspense mode if two or
more such winning outcomes appear possible for different win
lines.
[0074] Alternatively, it may be required that the total of the win
outcomes that appear possible across all win lines played by the
player exceed a prize threshold such that possible outcomes from
separate wins can contribute to that total. That is, apparent game
outcomes with prizes below the threshold on an individual win line
will not trigger a suspense mode but if the total of prizes that
appear possible after a certain number of reels exceeds the
threshold the suspense mode may be entered into. Different
thresholds may be set for different numbers of reels having spun to
a stop and/or different numbers of win lines.
[0075] Adjustments
[0076] The display may be adjusted by altering the duration of the
spinning of one or more reels. For example, if two aces appear on
the first reel and second reels, the duration of spinning of the
third reel may be extended.
[0077] Alternatively, the speed of spinning or a reel may be
adjusted. For example, if aces appear on the first four reels, the
duration of the spinning of the fifth reel may be the same but the
speed of the spinning of the fifth reel may be slowed so that the
player can more readily perceive the symbols on the reel as they
move into position or sped up as an indicator of excitement.
[0078] Another possible adjustment of the display is to reverse the
direction of spinning of the reel.
[0079] It is possible to combine variations of spinning. For
example, in an example where a winning outcome appears possible on
multiple reels, if a winning outcome appears possible on one reel,
the duration may be altered but if it appears possible on two win
lines, both duration and speed may be altered.
[0080] In certain embodiments, multiple duration and multiple speed
variations may be possible. The adjuster 656 may determine a size
of an adjustment dependent on: [0081] a) the size of the prize;
[0082] b) the number of reels in relation to which a suspense
condition is met; [0083] c) a number of suspense conditions that
are met; or [0084] d) the likelihood of a prize outcome.
[0085] For example, in a case where five aces appear on a reel, the
duration of the spin may be extended for a first time after two
aces appear, a second time after three aces appear and a third time
once four aces appear and it appears highly likely the player will
win the prize corresponding to five aces.
[0086] A suspense mode will be ended if a suspense condition is no
longer met and there are more reels to be spun.
EXAMPLE
[0087] Referring to FIG. 5 there is shown an exemplary display 500
that may occur during a game according to an embodiment. In the
gaming machine of FIG. 5 five lines of symbols 520A to 520E are
displayed on the display once all reels have spun to a stop. There
are five reels 510A to 510E. While five lines are displayed, only
three lines 530A, 530B and 530C are win lines. If the player
selects to play one win line, they play win line one 530A. Win line
two 530B is also played if they select two win lines and win line
three is added 530C if they select three win lines.
[0088] Consider an example where a player selects to play two win
lines. In this example a suspense mode is initiated if a Joker
symbol appears on one of the first two reels of a win line and
continues until a win line has two different symbols that are not
jokers. As the player is only playing two win lines, suspense mode
can only be activated in relation to these win lines. Assume that
reels one to five 510A to 510E are spun to a stop in numerical
order. In certain embodiments, the order of the reels displayed may
be varied depending on the embodiment. Once reel one has spun to a
stop, suspense mode is activated because the player has a Joker on
win line two. In this game a Joker acts as a wild symbol which may
be substituted for any of the other symbols. Thus irrespective of
the symbol that appears on win line two on reel two, the player
will have an increased apparent chance of winning. After reel two
spins to a stop there are two jokers on win line two and suspense
mode is maintained. After reel three, there is a King and two
Jokers on win line two and the suspense mode is maintained. When
reel four spins to a stop, a suspense condition is no longer met in
relation to win line two because there are two different symbols
apart from the Joker and hence a player can no longer obtain five
of the same symbols on win line two. Accordingly the machine
reverts to normal display mode.
[0089] Various modifications will be apparent to persons skilled in
the art, and should be understood as falling within the scope of
the appended claims.
[0090] For the purposes of this specification it will be clearly
understood that the word "comprising" means "including but not

[0092] While the invention has been described with reference to
certain embodiments, it will be understood by those skilled in the
art that various changes may be made and equivalents may be
substituted without departing from the scope of the invention. In
addition, many modifications may be made to adapt a particular
situation or material to the teachings of the invention without
departing from its scope. Therefore, it is intended that the
invention not be limited to the particular embodiment disclosed,
but that the invention will include all embodiments falling within
