Description

A GAMING DEVICE RELATED APPLICATION

[0001] This application is a divisional application of Australian patent application number 2021290285, which in turn is a divisional of Australian patent application number 2019264568, which in turn is a divisional of Australian patent application number 2018203323, the disclosure of which is incorporated herein by reference.

FIELD

[0002] The present application relates to an electronic gaming device and a method of operating a gaming device.

BACKGROUND

[0003] Electronic gaming machines ("EGMs") or gaming devices provide a variety of wagering games such as slot games, video poker games, video blackjack games, roulette games, video bingo games, keno games and other types of games that are frequently offered at casinos and other locations. Play on EGMs typically involves a player establishing a credit balance by inputting money, or another form of monetary credit, and placing a monetary wager (from the credit balance) on one or more outcomes of an instance (or single play) of a primary or base game. In many games, a player may qualify for secondary games or bonus rounds by attaining a certain winning combination or triggering event in the base game. Secondary games provide an opportunity to win additional game instances, credits, awards, jackpots, progressives, etc. Awards from any winning outcomes are typically added back to the credit balance and can be provided to the player upon completion of a gaming session or when the player wants to "cash out."

[0004] "Slot" type games are often displayed to the player in the form of various symbols arrayed in a row-by-column grid or matrix. Specific matching combinations of symbols along predetermined paths (or paylines) through the matrix indicate the outcome of the game. The display typically highlights winning combinations/outcomes for ready identification by the player. Matching combinations and their corresponding awards are usually shown in a "pay-table"

1 20602421_1 (GHMatters) P108488.AU.4 which is available to the player for reference. Often, the player may vary his/her wager to include differing numbers of paylines and/or the amount bet on each line. By varying the wager, the player may sometimes alter the frequency or number of winning combinations, frequency or number of secondary games, and/or the amount awarded.

[0005] Typical games use a random number generator (RNG) to randomly determine the outcome of each game. The game is designed to return a certain percentage of the amount wagered back to the player (RTP = return to player) over the course of many plays or instances of the game. The RTP and randomness of the RNG are critical to ensuring the fairness of the games and are therefore highly regulated. Upon initiation of play, the RNG randomly determines a game outcome and symbols are then selected which correspond to that outcome. Notably, some games may include an element of skill on the part of the player and are therefore not entirely random.

DETAILED DESCRIPTION

[0023] FIG. 1 illustrates several different models of EGMs which may be networked to various gaming related servers. The present invention can be configured to work as a system 100 in a gaming environment including one or more server computers 102 (e.g., slot servers of a casino) that are in communication, via a communications network, with one or more gaming devices 104A-104X (EGMs, slots, video poker, bingo machines, etc.). The gaming devices 104A-104X may alternatively be portable and/or remote gaming devices such as, but not limited to, a smart phone, a tablet, a laptop, or a game console.

[0024] Communication between the gaming devices 104A-104X and the server computers 102, and among the gaming devices 104A-104X, may be direct or indirect, such as over the Internet through a website maintained by a computer on a remote server or over an online data network including commercial online service providers, Internet service providers, private networks, and the like. In other embodiments, the gaming devices 104A-104X may communicate with one another and/or the server computers 102 over RF, cable TV, satellite links and the like.

[0025] In some embodiments, server computers 102 may not be necessary and/or preferred. For example, the present invention may, in one or more embodiments, be practiced on a stand-alone gaming device such as gaming device 104A, gaming device 104B or any of the other gaming devices 104C-104X. However, it is typical to find multiple EGMs connected to networks implemented with one or more of the different server computers 102 described herein.

6 20602421_1 (GHMatters) P108488.AU.4

[0026] The server computers 102 may include a central determination gaming system server 106, a ticket-in-ticket-out (TITO) system server 108, a player tracking system server 110, a progressive system server 112, and/or a casino management system server 114. Gaming devices 104A-104X may include features to enable operation of any or all servers for use by the player and/or operator (e.g., the casino, resort, gaming establishment, tavern, pub, etc.). For example, game outcomes may be generated on a central determination gaming system server 106 and then transmitted over the network to any of a group of remote terminals or remote gaming devices 104A-104X that utilize the game outcomes and display the results to the players.

[0027] Gaming device 104A is often of a cabinet construction which may be aligned in rows or banks of similar devices for placement and operation on a casino floor. The gaming device 104A often includes a main door 116 which provides access to the interior of the cabinet. Gaming device 104A typically includes a button area or button deck 120 accessible by a player that is configured with input switches or buttons 122, an access channel for a bill validator 124, and/or an access channel for a ticket printer 126.

[0028] In FIG. 1, gaming device 104A is shown as a Rem XLTM model gaming device manufactured by Aristocrat®Technologies, Inc. As shown, gaming device 104A is a reel machine having a gaming display area 118 comprising a number (typically 3 or 5) of mechanical reels 130 with various symbols displayed on them. The reels 130 are independently spun and stopped to show a set of symbols within the gaming display area 118 which may be used to determine an outcome to the game. In embodiments where the reels are mechanical, mechanisms can be employed to implement greater functionality. For example, the boundaries of the gaming display area boundaries of the gaming display area 118 may be defined by one or more mechanical shutters controllable by a processor. The mechanical shutters may be controlled to open and close, to correspondingly reveal and conceal more or fewer symbol positions from the mechanical reels 130. For example, a top boundary of the gaming display area 118 may be raised by moving a corresponding mechanical shutter upwards to reveal an additional row of symbol positions on stopped mechanical reels. Further, a transparent or translucent display panel may be overlaid on the

7 20602421_1 (GHMatters) P108488.AU.4 gaming display area 118 and controlled to override or supplement what is displayed on one or more of the mechanical reel(s).

[0029] In many configurations, the gaming machine 104A may have a main display 128 (e.g., video display monitor) mounted to, or above, the gaming display area 118. The main display 128 can be a high-resolution LCD, plasma, LED, or OLED panel which may be flat or curved as shown, a cathode ray tube, or other conventional electronically controlled video monitor.

[0030] In some embodiments, the bill validator 124 may also function as a "ticket-in" reader that allows the player to use a casino issued credit ticket to load credits onto the gaming device 104A (e.g., in a cashless ticket ("TITO") system). In such cashless embodiments, the gaming device 104A may also include a "ticket-out" printer 126 for outputting a credit ticket when a "cash out" button is pressed. Cashless TITO systems are well known in the art and are used to generate and track unique bar-codes or other indicators printed on tickets to allow players to avoid the use of bills and coins by loading credits using a ticket reader and cashing out credits using a ticket-out printer 126 on the gaming device 104A. In some embodiments a ticket reader can be used which is only capable of reading tickets. In some embodiments, a different form of token can be used to store a cash value, such as a magnetic stripe card.

[0031] In some embodiments, a player tracking card reader 144, a transceiver for wireless communication with a player's smartphone, a keypad 146, and/or an illuminated display 148 for reading, receiving, entering, and/or displaying player tracking information is provided in EGM 104A. In such embodiments, a game controller within the gaming device 104A can communicate with the player tracking server system 110 to send and receive player tracking information.

[0032] Gaming device 104A may also include a bonus topper wheel 134. When bonus play is triggered (e.g., by a player achieving a particular outcome or set of outcomes in the primary game), bonus topper wheel 134 is operative to spin and stop with indicator arrow 136 indicating the outcome of the bonus game. Bonus topper wheel 134 is typically used to play a bonus game, but it could also be incorporated into play of the base or primary game.

[0033] A candle 138 may be mounted on the top of gaming device 104A and may be activated by a player (e.g., using a switch or one of buttons 122) to

8 20602421_1 (GHMatters) P108488.AU.4 indicate to operations staff that gaming device 104A has experienced a malfunction or the player requires service. The candle 138 is also often used to indicate a jackpot has been won and to alert staff that a hand payout of an award may be needed.

[0034] There may also be one or more information panels 152 which may be a back-lit, silkscreened glass panel with lettering to indicate general game information including, for example, a game denomination (e.g., $0.25 or $1), pay lines, pay tables, and/or various game related graphics. In some embodiments, the information panel(s) 152 may be implemented as an additional video display.

[0035] Gaming devices 104A have traditionally also included a handle 132 typically mounted to the side of main cabinet 116 which may be used to initiate game play.

[0036] Many or all the above described components can be controlled by circuitry (e.g., a gaming controller) housed inside the main cabinet 116 of the gaming device 104A, the details of which are shown in FIG. 2.

[0037] Note that not all gaming devices suitable for implementing embodiments of the present invention necessarily include top wheels, top boxes, information panels, cashless ticket systems, and/or player tracking systems. Further, some suitable gaming devices have only a single game display that includes only a mechanical set of reels and/or a video display, while others are designed for bar counters or table tops and have displays that face upwards.

[0038] An alternative example gaming device 104B illustrated in FIG. 1 is the ArcTM model gaming device manufactured by Aristocrat® Technologies, Inc. Note that where possible, reference numerals identifying similar features of the gaming device 104A embodiment are also identified in the gaming device 104B embodiment using the same reference numbers. Gaming device 104B does not include physical reels and instead shows game play functions on main display 128. An optional topper screen 140 may be used as a secondary game display for bonus play, to show game features or attraction activities while a game is not in play, or any other information or media desired by the game designer or operator. In some embodiments, topper screen 140 may also or alternatively be used to display progressive jackpot prizes available to a player during play of gaming device 104B.

9 20602421_1 (GHMatters) P108488.AU.4

[0039] Example gaming device 104B includes a main cabinet 116 including a main door 118 which opens to provide access to the interior of the gaming device 104B. The main or service door 118 is typically used by service personnel to refill the ticket-out printer 126 and collect bills and tickets inserted into the bill validator 124. The door 118 may also be accessed to reset the machine, verify and/or upgrade the software, and for general maintenance operations.

[0040] Another example gaming device 104C shown is the HelixTM model gaming device manufactured by Aristocrat®Technologies, Inc. Gaming device 104C includes a main display 128A that is in a landscape orientation. Although not illustrated by the front view provided, the landscape display 128A may have a curvature radius from top to bottom, or alternatively from side to side. In some embodiments, display 128A is a flat panel display. Main display 128A is typically used for primary game play while secondary display 128B is typically used for bonus game play, to show game features or attraction activities while the game is not in play or any other information or media desired by the game designer or operator.

[0041] Many different types of games, including mechanical slot games, video slot games, video poker, video blackjack, video pachinko, keno, bingo, and lottery, may be provided with or implemented within the depicted gaming devices 104A-104C and other similar gaming devices. Each gaming device may also be operable to provide many different games. Games may be differentiated according to themes, sounds, graphics, type of game (e.g., slot game vs. card game vs. game with aspects of skill), denomination, number of paylines, maximum jackpot, progressive or non-progressive, bonus games, and may be deployed for operation in Class 2 or Class 3, etc.

[0042] FIG. 2 is a block diagram depicting exemplary internal electronic components of a gaming device 200 connected to various external systems. All or parts of the example gaming device 200 shown could be used to implement any one of the example gaming devices 104A-X depicted in FIG. 1. The games available for play on the gaming device 200 are controlled by a game controller 202 that includes one or more processors 204 and a game that may be stored as game software or a program 206 in a memory 208 coupled to the processor 204. The memory 208 may include one or more mass storage devices or media that

10 20602421_1 (GHMatters) P108488.AU.4 are housed within gaming device 200. Within the mass storage devices and/or memory 208, one or more databases 210 may be provided for use by the program 206. A random number generator (RNG) 212 that can be implemented in hardware and/or software is typically used to generate random numbers that are used in the operation of game play to ensure that game play outcomes are random and meet regulations for a game of chance. In some embodiments, the random number generator 212 is a pseudo-random number generator.

[0043] Alternatively, a game instance (i.e. a play or round of the game) may be generated on a remote gaming device such as a central determination gaming system server 106 (not shown in FIG. 2 but see FIG. 1). The game instance is communicated to gaming device 200 via the network 214 and then displayed on gaming device 200. Gaming device 200 may execute game software, such as but not limited to video streaming software that allows the game to be displayed on gaming device 200. When a game is stored on gaming device 200, it may be loaded from a memory 208 (e.g., from a read only memory (ROM)) or from the central determination gaming system server 106 to memory 208. The memory 208 may include RAM, ROM or another form of storage media that stores instructions for execution by the processor 204.

[0044] The gaming device 200 may include a topper display 216 or another form of a top box (e.g., a topper wheel, a topper screen, etc.) which sits above main cabinet 218. The gaming cabinet 218 or topper display 216 may also house a number of other components which may be used to add features to a game being played on gaming device 200, including speakers 220, a ticket printer 222 which prints bar-coded tickets or other media or mechanisms for storing or indicating a player's credit value, a ticket reader 224 which reads bar coded tickets or other media or mechanisms for storing or indicating a player's credit value, and a player tracking interface 232. The player tracking interface 232 may include a keypad 226 for entering information, a player tracking display 228 for displaying information (e.g., an illuminated or video display), a card reader 230 for receiving data and/or communicating information to and from media or a device such as a smart phone enabling player tracking. Ticket printer 222 may be used to print tickets for a TITO system server 108. The gaming device 200 may further include a bill validator 234, buttons 236 for player input, cabinet security sensors 238 to detect unauthorized opening of the cabinet 218,

11 20602421_1 (GHMatters) P108488.AU.4 a primary game display 240, and a secondary game display 242, each coupled to and operable under the control of game controller 202.

[0045] Gaming device 200 may be connected over network 214 to player tracking system server 110. Player tracking system server 110 may be, for example, an OASIS© system manufactured by Aristocrat Technologies, Inc. Player tracking system server 110 is used to track play (e.g. amount wagered, games played, time of play and/or other quantitative or qualitative measures) for individual players so that an operator may reward players in a loyalty program. The player may use the player tracking interface 232 to access his/her account information, activate free play, and/or request various information. Player tracking or loyalty programs seek to reward players for their play and help build brand loyalty to the gaming establishment. The rewards typically correspond to the player's level of patronage (e.g., to the player's playing frequency and/or total amount of game plays at a given casino). Player tracking rewards may be complimentary and/or discounted meals, lodging, entertainment and/or additional play. Player tracking information may be combined with other information that is now readily obtainable by a casino management system.

[0046] Gaming devices, such as gaming devices 104A-104X, 200, are highly regulated to ensure fairness and, in many cases, gaming devices 104A 104X, 200 are operable to award monetary awards (e.g., typically dispensed in the form of a redeemable voucher). Therefore, to satisfy security and regulatory requirements in a gaming environment, hardware and software architectures are implemented in gaming devices 104A-104X, 200 that differ significantly from those of general-purpose computers. Adapting general purpose computers to function as gaming devices 200 is not simple or straightforward because of: 1) the regulatory requirements for gaming devices 200, 2) the harsh environment in which gaming devices 200 operate, 3) security requirements, 4) fault tolerance requirements, and 5) the requirement for additional special purpose componentry enabling functionality of an EGM. These differences require substantial engineering effort with respect to game design implementation, hardware components and software.

[0047] When a player wishes to play the gaming device 200, he/she can insert cash or a ticket voucher through a coin acceptor (not shown) or bill validator 234 to establish a credit balance on the gamine machine. The credit

12 20602421_1 (GHMatters) P108488.AU.4 balance is used by the player to place wagers on instances of the game and to receive credit awards based on the outcome of winning instances. The credit balance is decreased by the amount of each wager and increased upon a win. The player can add additional credits to the balance at any time. The player may also optionally insert a loyalty club card into the card reader 230. During the game, the player views the game outcome on the game displays 240, 242. Other game and prize information may also be displayed.

[0048] For each game instance, a player may make selections, which may affect play of the game. For example, the player may vary the total amount wagered by selecting the amount bet per line and the number of lines played. In many games, the player is asked to initiate or select options during course of game play (such as spinning a wheel to begin a bonus round or select various items during a feature game). The player may make these selections using the player-input buttons 236, the primary game display 240 which may be a touch screen, or using some other input device which enables a player to input information into the gaming device 200. In some embodiments, a player's selection may apply across a plurality of game instances. For example, if the player is awarded additional game instances in the form of free games, the player's prior selection of the amount bet per line and the number of lines played may apply to the free games. The selections available to a player will vary depending on the embodiment. For example, in some embodiments a number of pay lines may be fixed. In other embodiments, the available selections may include different numbers of ways to win instead of different numbers of pay lines.

[0049] During certain game events, the gaming device 200 may display visual and auditory effects that can be perceived by the player. These effects add to the excitement of a game, which makes a player more likely to enjoy the playing experience. Auditory effects include various sounds that are projected by the speakers 220. Visual effects include flashing lights, strobing lights or other patterns displayed from lights on the gaming device 200 or from lights behind the information panel 152 (FIG. 1).

[0050] When the player is done, he/she cashes out the credit balance (typically by pressing a cash out button to receive a ticket from the ticket printer

13 20602421_1 (GHMatters) P108488.AU.4

222). The ticket may be "cashed-in" for money or inserted into another machine to establish a credit balance for play.

[0051] Figure 5 illustrates an embodiment of a gaming method 500 carried out by the processor 204 when the processor 204 executes program code 206 in memory 208. At step 505, the processor receives player selections as described above.

[0052] At step 510, the processor 204 conducts a base game instance. In one example, the base game instance is a reel based game.

[0053] FIG. 3 illustrates an example of a set 300 of five-reel strips 321, 322, 323, 324, 325. In the example, each reel strip has fifteen-reel strip positions 301-315. Each reel strip position of each reel has a symbol. For example, a "Wild" symbol 331 occupies the sixth reel strip position 306 of the fourth reel 324. Other reels strips to those illustrated in Figure 3 can be used, for example, reel strips where two or more wild symbols are placed at consecutive reel strip positions of a reel strip. In other examples, the reel strips could have between 30 and 100-reel strip positions. The length of the reel strips depend on factors such as the number of wild symbols (in general, the more wilds there are, the longer the reel strip needs to be to maintain the target RTP), and volatility (in general, the higher the prize value is, the longer the reel strip needs to be to lower the hit rate to maintain the target RTP).

[0054] FIG. 4 is a flow chart of a method 400 carried out by the processor 204 to select symbols from reel strips. At step 410, the processor 204 starts the process of selecting symbols with a counter (n) set at zero as symbols have not yet been selected from any reel strips. At step 420, the processor 204 increments the counter. In the first iteration, the counter is set to 1 to reflect that symbols are to be selected from a first reel strip. At step 430 the processor obtains a randomly generated number from a true or pseudo random number generator 212. At step 440 the processor maps the generated number to one of the reel positions of the nth reel strip. In the first iteration, this is the first reel strip. To map the generated number to one of the reel positions, the possible values that can be returned from the RNG 212 are divided into ranges and associated with specific ones of the reel positions in memory 208. In one example, these ranges are stored as a look-up table. In one example, the ranges are each the same size so that each of the reel strip positions has the same chance of been selected. In

14 20602421_1 (GHMatters) P108488.AU.4 other examples, the ranges may be arranged to weight the relative chances of selecting specific reel strip positions. The reel strips may be of different lengths.

[0055] At step 450, the processor 204 maps symbols of the nth reel strip to and nth column of symbol display positions based on the mapped reel position and a reference position. In an example, the reference position is the bottom position of the symbol positions of each column of symbol positions. In this example, the selected reel position (and hence the symbol at this position) is mapped to the bottom symbol position of the column. In an example, there are two other symbol positions in the column of symbol positions and hence symbols at two neighbouring reel strip positions are also mapped to the symbol positions of the column. Referring to the example reel strips of Figure 3, if the value returned by the RNG 212 is mapped to reel position 313, then for the first reel strip 321, "Pic3" symbol 343 is mapped to a bottom symbol position, "10" symbol 342 is mapped to a middle symbol position, and "J" symbol is mapped to a top symbol position.

[0056] At step 460, the processor 460 determines whether symbols have been selected for all of the reel strips, and if not, the processor reverts to step 420 and iterates through steps 430, 440 and 450 until it is determined at step 460 that symbols have been selected from all n reel strips and mapped to all n columns of symbol positions after which the symbol selection process ends 470. Different numbers of symbols may be mapped to different numbers of symbol positions.

[0057] After the symbols of all reel strips have been mapped to symbol position, the processor 204 controls display 240 to display them at the symbol positions. The processor 204 then evaluates the displayed symbols based on a pay table stored in memory 208 and the player's selections (e.g. the player's selected number of ways to win).

[0058] In embodiments of the invention, the displayed are also evaluated to determine whether a trigger condition is met at step 515 in order to determine whether to trigger a feature game.

[0059] If there is no trigger at step 515, the game ends 580.

[0060] If there is a relevant feature trigger at step 515, at step 520, the processor 204 controls display 240 to display a plurality of selectable game options. In one example, there are five displayed selectable options:

15 20602421_1 (GHMatters) P108488.AU.4

* A first option of 25 Free games using a 4x5 reel matrix of symbol positions 710 (as shown in Fig. 7A) with 12 "Feature Wild" symbols added relative to the reel strips used in the base game. • A second option of 10 Free games using a 5x5 reel matrix of symbol positions 720 (as shown in Fig. 7B) with 15 "Feature Wild" symbols added. • A third option of 5 Free games using a 6x5 reel matrix of symbol positions 730 (as shown in Fig. 7C) with 18 "Feature Wild" symbols added. • A fourth option of 3 Free games using a 7x5 reel matrix of symbol positions 740 (as shown in Fig. 7D) with 21"Feature Wild" symbols added. • A fifth, Mystery Choice, option which if selected results in the processor conducting a random selection between the four options set out above.

[0061] It will be apparent that the first option has a first number of feature game instances and uses a first set of symbol positions and a first symbol set while the second option has a second number of feature game instances and uses a second set of symbol positions and a second symbol set. It is also apparent that the first number of feature game instances is larger than the second number of feature game instances, the second set of symbol positions has more symbol positions than the first set of symbol positions, and the second symbol set has more occurrences of the "Feature Wild" symbol than the first symbol set.

[0062] It will also be apparent that the third option has a third number of feature game instances which is smaller than the second number of feature game instances, and uses a third set of symbol positions that has more symbol positions than the second set of symbol positions and a third symbol set that has more occurrences of the "Feature Wild" symbol than the second symbol set.

[0063] It will also be apparent that the fourth option has a fourth number of feature game instances which is smaller than the third number of feature game instances, and uses a fourth set of symbol positions that has more symbol positions than the third set of symbol positions and a fourth symbol set that has more occurrences of the "Feature Wild" symbol than the third symbol set.

[0064] In an alternative embodiment, the options use the same symbol set, for example, they include the same number of "Feature Wild" symbols.

16 20602421_1 (GHMatters) P108488.AU.4

[0065] At step 525, the processor 204 receives a player selection of one of the options for example by detecting a touch on the displayed option. If the player does not make a selection within a defined time period, the processor 204 deems this as a player selection of the random or "mystery choice" option.

[0066] At step 530, the processor 204 determines whether the random option has been selected. If the random option has been selected, the processor 204 uses the RNG to randomly select one of the other four options. In one example, the four other options are assigned equally weighted portions of the possible results that can be returned from the random number generator. The processor 204 cause the random number generator 212 to generate a number, compares the generated number to the look up table that associates the options with possible random number generator results, and determines based on the comparison which option is selected.

[0067] At step 540, the processor 204 initiates a counter of the number of game instances based on the selected option. For example, if the player selects the first option above, the counter is set to 25 free games. At step 545, the processor displays a set of symbol positions based on a selected option 545. In some examples, this may require the processor 204 to change the display to display additional symbol positions. That is, to display the relevant set of symbol positions as shown in Figure 7.

[0068] At step 550, the processor sets reel strips based on the selected option. For example, if the player selects the second option, the processor selects the reel strips that have 15 feature wild symbols added. It will be appreciated that the processor can set reel strips by selecting reel strips stored in the memory or by dynamically modify the base game reel strips to add the relevant number of feature wild symbols. For example, by adding three feature wild symbols to each of the five-reel strips at designated positions.

[0069] At step 552, the counter is decreased by 1 to reflect that a feature game instance is to be carried out.

[0070] At step 555, the processor 204 selects symbols from the set reels for the set symbol positions using the process as described in relation to figures 3 and 4 above.

[0071] At step 560, the processor evaluates the symbols displayed at symbol positions based on a pay table. At step 565, the processor determines

17 20602421_1 (GHMatters) P108488.AU.4 whether there are any winning combinations. If there are winning combinations, the processor 204 updates the win meter at step 570 by incrementing the value of the win meter in the memory and updating the display to display the current value of the win meter.

[0072] FIG. 8 illustrates one example of how the evaluation of the symbols based on the pay table can be altered by the processor 204 to accommodate the size of the set of symbol positions corresponding to the player's selected option while taking into account the player's initial wager selection. In these examples, the player's initial wager selection is of a number of ways to win.

[0073] Evaluation maps 810, 820, 830 illustrate different examples of selections of ways to win that apply, for example to a base game, conducted in respect of a set of symbol positions having an array of five columns and three rows of symbol positions. Evaluation maps 840, 850 and 860 show how this evaluation is altered if during the feature game, the player selects an option having more symbol positions than the base game, in this case an array of five columns and four rows of symbol positions. In each of the evaluation maps, the symbol positions that are used in evaluating the selected symbols are shaded.

[0074] Evaluation map 810 shows that the player has selected three ways to win. The three ways to win are derived by combining each symbol position from the left most column with the shaded symbol from the other columns. That is, any of the three symbols selected for the first column can be combined with the symbols in the shaded positions in the other four columns. It will be apparent from map 810 that the player's selection of three ways to win corresponds to a selection of the left most column. Evaluation map 840 shows that the evaluation for the feature game is derived from the player's selection of columns as the evaluation is formed by extending it to include the symbol positions of the additional row such that the player has four ways to win derived by combining each symbol position from the left most column, with each shaded symbol from the other columns - i.e. 4xlxlxlxl = 4.

[0075] Evaluation map 520 shows an example where the player has selected nine ways to win (or two columns of symbol positions). The nine ways to win are derived by combining each symbol position from the left most column and second to left columns with the shaded symbol from the other columns. This evaluation is modified for the feature game by incorporating the added symbol

18 20602421_1 (GHMatters) P108488.AU.4 positions from the additional row for both the left most column and second to left columns with the shaded symbol from the other columns as shown in evaluation map 550. As a result, there are 16 ways to win in each feature game instance i.e. 4x4xlxlxl = 16.

[0076] Evaluation map 530 shows an example where the player has selected 27 ways to win (or three columns of symbol positions). The 27 ways to win are derived by combining each symbol position from the three left most columns with the shaded symbol from the other columns. This evaluation is modified in for the feature game instances by incorporating the added symbol positions from the additional row for each of the three leftmost columns with the shaded symbol from the other columns as shown in evaluation map 560. As a result, there are 64 ways to win in the feature game instances - i.e. 4x4x4xlxl= 64.

[0077] It will be apparent from the above that the initial number of ways to win selected by the player, and the size of the set of symbol positions also impacts the size of the modified evaluation.

[0078] At step 575, the processor 204 determines whether the counter has reached "0" and if it has the game ends at step 580.

[0079] Referring to FIG. 6, there is shown an alternative embodiment where a player's wager selections affect the number of selectable options that are available for a feature game. The embodiment described in relation to Figure 6 can be used with the embodiment described in relation to Figure 5 such that, different numbers of the five selectable options available depending on the player's wager selections. In other examples, the embodiment described in relation to Figure 6 can be used with other selectable options. For example, selectable options where only the number of features game instances and designated symbols vary.

[0080] Referring to FIG. 6, at step 605, the processor 204 receives player selections input in accordance with the manner described above in order to specify a player wager. At step 610, the processor 204 conducts a base game, for example, in the manner described in relation to Figures 3, 4 and 5.

[0081] At step 615, the processor 204 determines whether a trigger condition is met. If a trigger condition is not met, the game ends 675.

19 20602421_1 (GHMatters) P108488.AU.4

[0082] At step 620, the method involves determining whether the player wager has a first characteristic. If the player has a first characteristic at step 630, the processor 204 controls the display 240 to display a first number of selectable options. For example, four selectable options. If the wager doesn't have the first characteristic, in this embodiment, as a result that the wager is deemed at step 625 to have the second characteristic. Other embodiments may involve taking into account more than two characteristics could be in controlling the number of selectable options that are displayed.

[0083] At step 635, because the wager has the second characteristic 625 a different number of selectable options is displayed. In an example, the number of selectable options of the second option is five selectable options.

[0084] In an example, the first and second characteristics relate to sizes of the wager. In an example, the first characteristic is that the wager is below a first amount and the second characteristic is that the player wager is at least a second amount greater than the first amount. In one example, the second amount is the maximum wager that can be placed on the game. Other examples of characteristics of a player wager include a selected number of ways to win or a selected number of paylines.

[0085] At step 640, the processor initiates a counter based on the selected options. That is, a counter corresponding to the number of feature game instances of the selected outcome.

[0086] At step 645, the processor 204, sets the reel strips to be used based on the selected option in a manner similar to that described in relation to Figure 5 above.

[0087] At step 650, the processor selects symbols from the set of reel strips for display at a set of symbol positions. In this example, the set of symbol positions is the same for each feature game instance irrespective of the selected options. In another example, the sets of symbol positions may vary in the manner described in relation to Figure 5 above.

[0088] At step 655, the processor 204 evaluates the symbols based on the pay table and at step 660, the processor 204 determines whether there are any winning combinations. If there are winning combinations, the processor updates the win meter at step 665. If there are no winning combinations, the processor

20 20602421_1 (GHMatters) P108488.AU.4 proceeds directly to steps 667 and decreases the counter value by one to reflect that a feature game instance has been conducted.

[0089] At step 670, the processor 204 determines whether the counter has reached zero and if not returns to step 650 of selecting a further set of symbols from the set of reel strips. When the counter reaches zero, the game ends 675.
