An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 illustrates an exemplary display on a liquid crystal display (LCD: first display) 16 of a slot machine 10 of the present embodiment. As shown in FIG. 1, the LCD 16 has nine slot game areas A1 to A9 (simply referred to as “areas”, hereinafter) arranged in a matrix. A slot game is executed on each of the areas A1 to A9.
Each of the areas A1 to A9 has nine (three rows by three columns) display areas q11 to q33 (FIG. 4). When a bet is placed on any of the areas A1 to A9, the area on which the bet has been placed is activated. Subsequently, symbols displayed (arranged) on display areas q11 to q33 of the activated area(s) are scrolled simultaneously when the start switch 27 has been pressed. And then, the scrolling is finished to stop (rearrange) the symbols at the same time. A payout is awarded to the player when a winning combination has been achieved on any of the paylines of the activated area. Thus, the slot game is a game in which arranged symbols is rearranged for determining whether or not a payout is awarded according to rearranged symbols.
Here, an example is described in which symbols are scrolled in each slot game and then the symbols are stopped. However, displaying method of the symbols is not limited to scrolling. For example, new symbols may be stopped (rearranged) after each of the symbols in the display areas is switched over successively.
FIG. 2 illustrates an example of an upper display (second display) 33 of the slot machine 10. The upper display 33 includes an area A10. The area A10 has display windows R1 to R3 aligned laterally as a single row. A mechanical reel 3A (FIG. 9) is provided behind the display window R1. A plurality of symbols is drawn on the circumferential surface of the reel 3A. The circumferential surface faces the display window R1. When the reel 3A stops, a symbol comes to a stop (arranged) within the display window R1. When the reel 3A spins, the symbol scrolls within the display window R1. Subsequently, when the reel 3A stops again, a symbol comes to a stop (rearranged) within the display window R1. A mechanical reel 3B is provided behind the display window R2 and a mechanical reel 3C is provided behind the display window R3. The display windows R2 and R3 are similar to the display window R1, and the reels 3B and 3C are similar to the reel 3A. The area A10 is used for a bonus game (extra slot game) described below.

The start switch 27 is connected to the interface circuits 102. A start signal output from the start switch 27 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.
The bet switch 25, the max-bet switch 24, the spin/repeat-bet switch 26, and the cash-out switch 23 are connected to the interface circuits 102. A switching signal output from each of the switches 23 to 26 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.
A medal sensor (input device) 43 is connected to the interface circuits 102. A bet amount by the player's inserting a medal(s) can be detected via the medal sensor 43. The medal sensor 43 detects a medal(s), which has been inserted into the medal insertion slot 21. The medal sensor 43 is provided inside the medal insertion slot 21. The detection signal output from the medal sensor 43 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.
A reel position detecting circuit 46 is connected to the interface circuits 102. The reel position detecting circuit 46 detects each current spinning or stopped position of the reels 3A to 3C. The detection signal output from the reel position detecting circuit 46 is transmitted to the CPU 106 via the I/O bus 104.
The ROM 108 storing system programs and the payout table, and the RAM 110 storing various data are connected to the I/O bus 104. The RNG 112, the signal communication I/F circuit 111, the motor drive circuit 120, the display controller 140, the hopper drive circuit 124, the speaker drive circuit 122, and the display control circuit 128 are connected to the I/O bus 104.
The CPU 106, triggered by receiving the start signal from the start switch 27, reads a game execution program among the system programs and executes a game. The game execution program is a program for executing the slot game in each of the areas A1 to A9 on the LCD 16 using the display controller 140.
In other words, the game execution program is programmed so as to execute a slot game in which symbols are rearranged after scrolling simultaneously on each of the areas A1 to A9 and a payout is provided when a winning combination is achieved on an activated payline.
The signal communication I/F circuit 111, which is connected to a hall server etc., transmits gaming history data etc. of the slot machine 10 to the hall server. The signal communication I/F circuit 111 receives various data transmitted from the hall server.
The RNG 112 generates a random number for determining whether or not to achieve a winning combination in the slot game on each of the areas A1 to A9.

The motor 45C spins the reel 3C and stops the spinning reel 3C. The motor driving circuit 120 is controlled by the CPU 106 to drive the reels 3A to 3C.
The display control circuit 128 controls displaying the total credit amount on the payout counter 48 provided at the lower left area of the LCD 16.
The speaker drive circuit 122 outputs sound data to the speakers 29. In other words, the CPU 106 reads the sound data stored in the ROM 108 and transmits the sound data to the speaker drive circuit 122 via the I/O bus 104. In this manner, predetermined sound effects are generated via the speakers 29.
The hopper drive circuit 124 outputs a cash-out signal to the hopper 44 when providing a cash-out. In other words, the CPU 106 outputs a drive signal to the hopper drive circuit 124 via the I/O bus 104 when receiving the cash-out signal from the cash-out switch 23. As a result, the hopper 44 cashes out medals equivalent to the total credit amount.
The display controller 140 controls the execution of the slot game on each of the areas A1 to A9. In detail, the CPU 106 generates an image display signal according to status and an outcome of the slot game on each of the areas A1 to A9 and outputs the image display signal to the display controller 140 via the I/O bus 104. Upon receipt of the image display signal, the display controller 140 generates a drive signal of the LCD 16 based on the image display signal. And then, the display controller 140 outputs the drive signal to the LCD 16. In this manner, the predetermined images are displayed on the LCD 16.
Next, an operation of the slot machine of the present embodiment is described with reference to flowcharts shown in FIG. 10 to FIG. 13. FIG. 10 is a flowchart showing a main processing.
The CPU 106 determines whether or not a bonus flag B is “0” (step S10). The processing flow proceeds to step S11 if B=0, and otherwise to step S16-1. Here, the bonus flag B is set to “1” if the bonus game starting condition has been met. The initial value of the bonus flag B is “0”. The bonus flag B is stored in the RAM 110.
A player places a bet with a desired bet amount on a slot game on each of the areas A1 to A9 by pressing the max-bet switch 24, the bet switch 25, or the spin/repeat-bet switch 26 (step S11). Alternatively, the player places a bet by inserting a desired number of medals into the medal insertion slot 21. In the present embodiment, each bet is placed a slot game on each of the areas A1 to A9 in an ascending order of the area numbers. For example, when 15 credits are bet, the 1st to 9th credits are bet as a 1st-bet on a slot game on each of the areas A1 to A9, and the 10th to 15th credits are bet as a 2nd-bet on the slot game on each of the areas A1 to A6. Thus, two credits are bet on the areas A1 to A6 and one credit is bet on the areas A7 to A9.
The CPU 106 (FIG. 9) subtracts the credit(s) corresponding to the bet amount from the total credit amount when a bet(s) is placed by pressing the max-bet switch 24, the bet switch 25, or the spin/repeat-bet switch 26 (step S12). For example, if 27 credits are bet when the total credit amount is 50 credits, the total credit amount becomes 50−27=23 credits.
Next, the CPU 106 activates the area(s) on which a bet has been placed (step S13).
The CPU 106 determines payline(s) to be activated on the activated area(s) (step S14). As described above, the line L1 (FIG. 5) is activated on the area(s) on which a 1-credit bet has been placed, the lines L1, L2 and L3 are activated on the area(s) on which a 2-credit bet has been placed, and all of the lines L1 to L5 are activated on the area(s) on which a 3-credit bet has been placed. The CPU 106 lights up the activation indicating frame(s) 51 of the activated area(s) to notify the player.
Subsequently, the CPU 106 determines whether or not the start switch 27 has been pressed (step S15). If the start switch 27 has been pressed, a slot game execution processing (FIG. 11) is executed for the activated area(s) (step S16).
On the other hand, if the bonus flag B is “1” in step S10 (step S10: NO), the CPU 106 waits until the start switch 27 is pressed (step S16-1). And then, the processing flow proceeds to step S16-2 when the start switch 27 has been pressed.
If step S16-1 is affirmative, the CPU 106 executes a bonus game execution processing (FIG. 13) (step S16-2). Subsequently, the CPU 106 terminates the main processing.
Next, the slot game execution processing executed for the activated area(s) will be described with reference to FIG. 11.
The CPU 106 first determines symbols to be stopped (7, BELL, APPLE, etc.) in each display area q11 to q33 of the areas A1 to A9 (step S23).
Subsequently, the CPU 106 scrolls symbols in each column of the display areas q11 to q33 of the areas A1 to A9 (step S24). On this occasion, scrolling of symbols is started simultaneously on the areas A1 to A9. In other words, scrolling of symbols is started on all of the areas A1 to A9 simultaneously when the start switch 27 has been pressed.
Then scrolling symbols is terminated after a predetermined time has elapsed (step S25) and symbols come to a stop in each of the display areas q11 to q33 on all of the areas A1 to A9. The stopped symbols were the symbols determined in step S23. On this occasion, the scrolling of symbols is terminated at the same time on the areas A1 to A9. The CPU 106 lights up the payout indicator(s) 52 of the area(s) on which a winning combination has been achieved on the activated payline.
Then, the CPU 106 determines whether or not the bonus game starting condition has been met (step S26). In other words, it is determined whether or not three areas each having an identical winning combination on the activated payline are aligned vertically, laterally, or diagonally. The CPU 106 advances the processing flow to step S27 if the bonus game starting condition is met and otherwise advances the processing flow to step S28.
If step S26 is affirmative, the CPU 106 executes a bonus game starting processing (step S27). The bonus game starting processing will be described below with reference to FIG. 12.
On the other hand, if step S26 is negative, the CPU 106 determines whether or not a winning combination has been achieved on the activated payline (step S28). If a winning combination has been achieved (step S28: YES), the CPU 106 executes a payout processing for awarding a payout to the player according to the winning combination(s) (step S29). In the payout processing, if a winning combination has been achieved on plural activated areas, the payout is provided in a lump sum for winning combinations on plural activated areas.
On the other hand, if no winning combination has been achieved (step S28: NO), the CPU 106 terminates the slot game execution processing without awarding a payout. Here, there are cases such that medals corresponding to a payout amount are cashed out from the cash-out chute 28 and that credits corresponding to a payout amount are added to the total credit amount.
Next, the procedure of the bonus game starting processing will be described with reference to the flow chart shown in FIG. 12. The CPU 106 first sets the bonus flag B to “1” (step S31). Subsequently, the CPU 106 determines the number of bonus games T (step S32). The number of games T is 50, for example. The number of games T may be a constant number, or may be determined randomly by the CPU 106 each time. The number of games T is stored in the RAM 110.
Subsequently, the CPU 106 provides a payout to the player (step S33). If winning combinations have been achieved on plural activated areas, the CPU 106 provides a payout to the player in a lump sum according to the winning combinations. In addition, in the present embodiment, a 15-credit payout is provided to the player as an award of getting the bonus game, for example. Then the CPU 106 terminates the processing.
If the bonus flag is set to “1” in the bonus game starting processing (FIG. 12), the bonus game execution processing (step S16-2) is executed after step S10 becomes negative in the next main processing (FIG. 10).
Next, the bonus game execution processing will be described with reference to the flow chart shown in FIG. 13. The CPU 106 first determines symbols to be stopped in each of the display windows R1 to R3 of the area A10 on the upper display 33 (step S41). Here, a winning combination is achieved with a higher probability than in the slot games on the areas A1 to A9. In other words, a symbol combination of three 7's, a symbol combination of three BELLs, and a symbol combination of three APPLEs, or a symbol combination including a left-most CHERRY shown in FIG. 7 is achieved with the higher probability in a bonus game on the area A10 than in a slot game on each of the areas A1 to A9.
Subsequently, the CPU 106 starts scrolling of symbols by spinning the reels 3A to 3C (step S42). Subsequently, the CPU 106 stops the spinning reels 3A to 3C so that symbols are rearranged, which were determined in step S41 (step S43).
Then, the CPU 106 determines whether or not a winning combination has been achieved on the area A10 (step S44). If a winning combination has been achieved (step S44: YES), a payout is awarded to the player according to the winning combination (step S45). Otherwise, if no winning combination has been achieved (step S44: NO), the CPU 106 does not award a payout.
Subsequently, the CPU 106 decrements the number of games T=T−1 stored in the RAM 110 (step S46).
The CPU 106 determines whether or not the number of games T stored in the RAM 110 is “0” (step S47). If T=0, the bonus flag B is reset to “0” (step S48). In other words, if the predetermined number of bonus games T has played out, the CPU 106 resets the bonus flag B and terminates the bonus game. The bonus game is an extra slot game executed on the area A10, in which a winning combination will be achieved with the higher probability in a bonus game on the area A10 than in a slot game on each of the areas A1 to A9. Of course, the bonus game may be another type of game.
As described above, with the slot machine 10, a slot game area(s) which has accepted a bet via an input device(s) (i.e., slot game area(s) on which a bet has been placed) is activated among the slot game areas A1 to A9, and a slot game is executed on the activated slot game area(s). Furthermore, with the slot machine 10, a bonus game is executed when three slot game areas awarding a payout have been aligned vertically, laterally, or diagonally.
Therefore, according to the slot machine 10, a new entertaining feature is provided in that whether or not a bonus game is executed is determined based on the arrangement of slot game areas awarding a payout.
Particularly, according to the slot machine 10, a bonus game is executed when three slot game areas each having an identical winning combination have been aligned vertically, laterally, or diagonally.
Thus, according to the slot machine 10, a new entertaining feature is provided in that whether or not a bonus game is executed is determined based on the arrangement of the slot games areas awarding a payout and the relationship among the slot game areas awarding a payout.
Furthermore, according to the slot machine 10, a bonus game is executed on the upper display 33 which is provided independently from the LCD 16 having the slot game areas A1 to A9. Therefore, the player can receive a stronger impact by starting a bonus game than when a bonus game is executed on the LCD 16.
Therefore, the player can place bets on plural slot games in a lump and then slot games are executed on the slot game areas individually. Thus, according to the slot machine 10, a player can relief from a cumbersome betting operation compared with a conventional slot machine in which a player has to place a bet on a slot game one by one.
The slot machine or the control method of the slot machine of the present invention has been described based on the embodiment. However, the present invention is not limited to the embodiment. Arrangement of respective components of the present invention may be replaced by any components having similar functionalities.
