2. Description of the Related Art
In a conventional slot machine, the number of BETs placed on a game is set by input operation, whereas a plurality of symbols are displayed in a scrolling manner by input operation made to a SPIN button and are then automatically displayed in a stopped manner on a display device provided at a front face of a casing. As described above, a game is started in the slot machine by a player's operating the SPIN button after operating a BET button. An example of conventional slot machines is disclosed in US Published Patent Application No. 20070123332 A1, in which a player performs operation twice, i.e., operation to a BET button and operation to a SPIN button.
Further, the conventional slot machine is provided with a CONTINUOUS PLAY switch, control of which renders the slot machine in a continuous play mode. In the continuous play mode, as long as the credit remains enough to play a game, reels are automatically controlled in a rotational manner in each game to automatically execute another game in a continuous manner. The slot machine as mentioned above is disclosed in U.S. Pat. No. 6,935,949 B1.

A main CPU 41 included in the slot machine 10 according to this embodiment stores in the RAM 43, BET information including the number of BETs placed in a previous game. The main CPU 41 judges whether or not a UTILITY switch is set to ON, as shown in
Next, upon judging that the UTILITY switch is set to ON (S10: YES), the main CPU 41 reads out the current credit amount and BET information concerning a previous game stored in a RAM 43 (step S11). The main CPU 41 then judges whether or not the current credit amount read out of the RAM 43 is greater than or equal to the number of BETs placed in the previous game (step S12). On the other hand, upon judging that the UTILITY switch is not set to ON (S10: NO), the main CPU 41 judges whether or not a BET switch is set to ON. When the BET switch is judged as being set to ON, the number of BETs is set in accordance with operation through the BET button, as per normal (step S3), and a scroll-display starting process is executed in accordance with operation made to the SPIN button.
Next, the main CPU 41 executes a BET number automatic setting process upon judging that the current credit amount is greater than or equal to the number of BETs placed in the previous game (S12: YES). Here, the main CPU 41 automatically sets the number of BETs equal to that of BETs placed in the previous game, based upon the auto-BET signal A1 received at step S10 and the number of BETs placed in the previous game included in the BET information, by referring to the BET information concerning the previous game read out of the RAM 43 at step S11 (step S14).
Next, the main CPU 41 automatically executes the scroll-display starting process to the plural types of symbols, based upon the auto-SPIN signal A2 received at step S10 (step S16). When a predetermined time has elapsed after start of the scroll-display, the main CPU 41 displays (rearranges) the plural types of symbols in a stopped manner, following stop of the scroll-display (step S18).
The main CPU 41 then counts the number of symbols of the same type, rearranged in the respective display blocks 28. As a result of counting, in a case where three or more symbols of the same type, which are set as a trigger for a scatter prize, are rearranged in any of the display blocks 28, the main CPU 41 pays out coins in accordance with the number and type of scatter symbols and the number of BETs (S20). The main CPU 41 executes a future game as a special prize in a case where three or more symbols “EARTH”, which are set as a trigger for the special prize, are rearranged (S22).

Scatter symbols include one set for a special prize and one set for a scatter prize. In every game, the scatter symbols are automatically displayed (rearranged) in a scrolling and stopped manner in the respective display blocks 28 of the lower image display panel 16. A special prize (future game) is established when a predetermined number or more of trigger symbols set for the special prize are displayed in a stopped manner. Further, a predetermined number or more of trigger symbols set for the scatter prize are displayed in a stopped manner, a scatter prize (payout of a predetermined number of coins) is established in accordance with the type and number of displayed scatter symbols and the number of BETs. A scatter symbol is simply referred to a symbol as appropriate in the following description because all of the symbols are set to scatter symbols.
The symbol “EARTH” is a trigger symbol for a special prize. In a case where the three or more symbols “EARTH” are displayed in a stopped manner in any of the display blocks 28, a special prize is established and a process of a future game as the special prize is executed. In this future game process, a player executes a free game, the number of which was determined based upon the random number values obtained by executing a random number generation program included in symbol determination programs.
An outline of the game will be described hereinafter. BET information (such as the number of BETs) on a previous game is stored in the RAM 43 in advance. When the next game is started, the main CPU 41 accepts operation that a player made to the UTILITY button 200, and receives the auto-BET signal A1 (the first instruction signal) output from the auto-BET circuit 210 and the auto-SPIN signal A2 (the second instruction signal) output from the auto-SPIN circuit 220 in accordance with the input operation to the UTILITY button 200. The main CPU 41 automatically sets BETs equal to the number of BETs placed on a previous game, based upon the received auto-BET signal A1 and the BET information concerning the previous game stored in the RAM 43. The main CPU 41 then automatically executes a process of starting scroll-display of the plural types of symbols, based upon the received auto-SPIN signal A2. When a predetermined time has elapsed after start of the scroll-display, the main CPU 41 displays (rearranges) the plural types of symbols in a stopped manner in the respective display blocks 28, following stop of the scroll-display. The main CPU 41 then counts the number of symbols of the same type having been rearranged in the respective display blocks 28. As a result of counting, in a case where three or more symbols of the same type, which are set as a trigger for a scatter prize, are rearranged in any of the display blocks 28, the main CPU 41 pays out coins in accordance with the number and type of scatter symbols and the number of BETs. The main CPU 41 executes a future game as a special prize in a case where three or more symbols “EARTH”, which are set as a trigger for the special prize, are rearranged.

In the present invention, the contents of the ROM 42 may be rewritable or not.
The RAM 43 stores data and programs used when the main CPU 41 is activated. The RAM 43 can also store game programs. The RAM 43 stores information concerning BETs placed on a previous game (such as the number of BETs and a predetermined symbol or a predetermined payline as a BET object), the number of symbols arranged in the respective display blocks 28, the amount of credit, the number of coins inserted in one game, the amount of payout, and the like.
Both a body PCB (Printed Circuit Board) 60 and a door PCB80, which will be described later, are connected to the motherboard 40 by the USB. Further, a power unit 45 is connected to the motherboard 40.
To the main body 60 and the door PCB 80, equipment or devices, for generating an input signal input to the main CPU 41, and those of which operation is controlled by means of a control signal output from the main CPU 41, are connected. The main CPU 41 executes the game programs stored in RAM 43, based upon an input signal that was input to the main CPU 41, thereby performing a predetermined computational process. Then, this CPU 41 stores results thereof into RAM43; and transmits control signals to equipment and devices as a control process relative to the equipment and devices.
Connected to the main body PCB 60 are a lamp 30, a hopper 66, a coin detection section 67, a graphic board 68, a speaker 29, a touch panel 69, a bill validator 22, a ticket printer 35, a card reader 36, a key switch 38S, and a data display 37. The lamp 30 lights in a predetermined pattern, based upon a control signal output from the main CPU 41.
The hopper 66 is installed in a cabinet 11, and a predetermined number of coins are paid out from the coin payout opening 19 to the coin tray 18, based upon the control signal output from the main CPU 41. A coin detection section 67 is provided inside of the coin payout opening 19, and outputs an input signal to the main CPU 41, if it is detected that a predetermined number of coins have been paid out from the coin payout opening 19.
The graphic board 68 performs control, based upon a control signal output from the main CPU 41, over the image display on the upper image display panel 33 and the lower image display panel 16 serving as an output device. Each of the display blocks 28 of the lower image display panel 16 displays symbols that are displayed in a scrolling manner or in a stopped manner, which is determined by selecting a random number value. The credit amount display portion 31 on the lower image display panel 16 displays the amount of credits stored in the RAM43. Further, a payout amount display portion 32 on the lower image display panel 16 displays the number of coins to be paid out. The graphic board 68 is provided with: a VDP (Video Display Processor), which generates image data, based upon the control signal output from the main CPU 41; and a video RAM, etc., which temporarily stores image data generated by the VDP. The image data used when the image data is generated by the VDP is read from the memory card 53, and thereafter, is included in the game programs stored in the RAM 43.
The bill validator 22 validates whether or not a bill is legitimate and accepts a legitimate bill into the cabinet 11. The bill validator 22, upon accepting a legitimate bill, outputs an input signal to the main CPU 41 based upon the bill amount. The main CPU 41 stores in the RAM 43 the amount of credits responsive to the amount of bills transmitted by the input signal.
The ticket printer 35, based upon a control signal output from the main CPU 41, prints on a ticket a bar code obtained by encoding data such as the number of credits, date and time, and the identification number of the slot machine 10 stored in the RAM43. The card reader 36 reads data from a smart card, thereby transmitting the read data to the main CPU 41 or writing data into the smart card, based upon the control signal from the main CPU 41. The key switch 38S is provided on the key pad 38, and outputs a predetermined input signal to the main CPU 41 when a player operates the key pad 38. The data display 37 displays, based upon a control signal output from the main CPU 41, the data read by the card reader 36 and the data input by a player through the key pad 38.
To the door PCB 80, a control panel 20, a reverter 21S, a coin counter 21C, and a cold cathode-ray tube 81 are connected. On a control panel 20, there are provided: the auto-BET switch 210S and the auto-SPIN switch 220S corresponding to the UTILITY button 200; a RESET switch 230S corresponding to the RESET button 230; a SPIN switch 23S corresponding to the SPIN button 23; a CHANGE switch 24S corresponding to the CHANGE button 24; a CASHOUT switch 25S corresponding to the CASHOUT button 25; a 1-BET switch 26S corresponding to the 1-BET button 26; and a MAX-BET switch 27S corresponding to the MAX-BET button 27. When a player operates the buttons 200, 230, and 23 to 27, the corresponding switches 210S, 220S, 230S, and 23S to 27S output input signals to the main CPU 41.
The coin counter 21C is provided inside the coin receiving slot 21, and validates whether or not a legitimate coin is inserted into the coin receiving slot 21. Those other than the legitimate coins are discharged from the coin payout exit 19. The coin counter 21C outputs an input signal to the main CPU 41 when a legitimate coin is detected.
The reverter 21S is operable based upon the control signal output from the main CPU 41. This reverter distributes the coins recognized to be legitimate by the coin counter 21C, into a cashbox (not shown) or a hopper 66 which was installed in the slot machine 10. In other words, if the hopper 66 is filled with coins, the legitimate coins are distributed to the cashbox by means of the reverter 21S. Otherwise, the legitimate coins are distributed to the hopper 66. The cold cathode-ray tube 81 functions as a backlight installed at the rear side of the lower image panel 16 and the upper image display panel 33, and lights based upon the control signal that was output from the main CPU 41.
A process executed in the slot machine 10 will be described next with reference to the drawings. The main CPU 41 progresses the game by reading out and executing a game program stored in the RAM 43.
A game execution process will be described with reference to
First, the main CPU 41 judges at step S10, whether or not the UTILITY switch is in its ON state. The UTILITY switch being in its ON state indicates that the auto-BET circuit 210 and the auto-SPIN circuit 220 are controlled to its closed state with the contact piece 200A of the UTILITY button 200 reciprocated in accordance with the input operation. Specifically, the main CPU 41 judges whether or not it receives the auto-BET signal A1 (the first instruction signal) output from the auto-BET circuit 210 and the auto-SPIN signal A2 (the second instruction signal) output from the auto-SPIN circuit 220, upon the input operation performed by a player to the UTILITY button 200. The auto-BET circuit 210 and the auto-SPIN circuit 220 output the auto-BET signal A1 and the auto-SPIN signal A2, respectively, (see
Next explained is a normal process executed in the slot machine in a case where the routine proceeds to step S2. At step S2, the main CPU 41 judges whether or not the BET switch is in its ON state. Specifically, the main CPU 41 judges whether or not it receives signals output from the BET switches 26S, 27S in accordance with operation performed by a player to the BET buttons 26, 27. In a case of receiving these signals, the main CPU 41 executes a process of setting the number of BETs in accordance with operation performed to the BET button. The routine proceeds to step S4 at which the main CPU 41 subtracts the number of coins corresponding to the set number of BETs from the credit amount stored in the RAM 43. The routine proceeds to step S5 at which the main CPU 41 judges whether or not the SPIN switch is in its ON state. Specifically, the main CPU 41 judges whether or not it receives a signal output from the SPIN switch 23S in accordance with operation performed by a player to the SPIN button 23. In a case of receiving the signal, the routine proceeds to step S6 at which the main CPU 41 executes a process of starting scroll-display of the plural types of symbols. Next, the routine proceeds to step S17 at which the main CPU 41 executes a process of selecting symbols by lottery, i.e., a symbol selecting process, to be described later.
A process executed in a case where the routine proceeds to step S11 will be described. At step S11, the main CPU 41 executes a process of reading BET information concerning the previous game. Specifically, the main CPU 41 reads out the number of BETs included in the BET information concerning the previous game stored in the RAM 43. The BET information includes the number of BETs placed in the previous game and a symbol or a payline on which BETs are placed.
Next, the main CPU 41 judges at step S12, whether or not the electrically stored amount of credit is greater than or equal to the number of BETs placed in the previous game read out of the RAM 43 at step S11. In a case where the main CPU 41 judges that the credit amount is greater than or equal to the number of BETs placed in the previous game (S12: YES), the routine proceeds to step S14. In a case where the main CPU 41 judges that the credit amount is smaller than the number of BETs placed in the previous game (S12: NO), the routine proceeds to step S13.
Next, at step S13, the main CPU 41 executes a process of accepting additionally inserted coins. Specifically, the main CPU 41 displays on the lower image display panel 16 or the upper image display panel 33, information for prompting a player to insert coins. Accordingly, where coins are inserted by the player, the number of inserted coins is added to the credit amount. When the number of coins is added to the credit amount, the main CPU 41 stores the credit amount in the RAM 43 while repeating the process at step S12.
Next, at step S14, the main CPU 41 executes a process of automatically setting the number of BETs. Specifically, the main CPU 41 automatically sets the number of BETs equal to the BETs placed in the previous game, based upon the auto-BET signal A1 output from the auto-BET circuit 210 and the BET information concerning the previous game read out of the RAM 43 at step S11. The main CPU 41 then stores in the RAM 43, the BET information including the number of BETs set for this game.
Next, at step S15, the main CPU 41 executes a process of subtracting from the credit amount. Specifically, the main CPU 41 reads out the BET information stored in the RAM 43 at step S14 and the electrically stored amount of credit, thereby subtracting the number of coins corresponding to the number of BETs set at step S14, from the amount of credit. The main CPU 41 then stores again the credit after subtraction in the RAM 43.
Next, at step S16, the main CPU 41 executes a process of automatically starting scroll-display. Specifically, the main CPU 41 automatically starts scroll-display of the plural types of symbols, based upon the auto-SPIN signal A2 output at step S11 from the auto-SPIN circuit 220.
At step S17, the main CPU 41 then executes a symbol selecting process after completion of the process at step S6 or step S16. Specifically, the main CPU 41 executes a symbol selecting program stored in the RAM 43, thereby determining a code number at the time of stop of scrolling of the symbols. This process will be described later with reference to
Next, at step S18, the main CPU 41 executes a process of stopping scroll-display. Specifically, when a predetermined time has elapsed after start of scroll-display of the plural types of symbols, the main CPU controls display such that the symbols determined at step S17 are displayed in a stopped manner in the respective display blocks 28 along with the stop of the scroll-display.
Next, at step S19, the main CPU 41 judges whether or not a scatter prize is established. Specifically, the main CPU 41 judges whether or not the scatter prize is established by determining whether or not three or more symbols for the scatter prize are displayed in a stopped manner in any of display blocks 28. More specifically, this CPU judges whether or not three or more symbols of the same type are displayed based upon
Next, at step S20, the main CPU 41 executes the coin payout process. Specifically, upon judging at step S19 that three or more symbols of the same type as a trigger symbol for scatter prize are displayed in a stopped manner in the display blocks 28, based on
Next, at step S21, the main CPU 41 judges whether or not a special prize is established. In this case, the main CPU 41 judges whether or not three or more symbols “EARTH” as a trigger for a special prize are displayed in a stopped manner. In a case where the main CPU 41 judges that the special prize is established (S21: YES), the routine proceeds to step S22. In a case where the main CPU 41 judges the special prize is not established (S21: NO), this subroutine is completed.
Next, at step S22, the main CPU41 executes a future game process. Specifically, upon judging at step S21 that the special prize is established, the main CPU 41 reads out of the RAM 43, a program for executing the future game process. The main CPU 41 then executes a random number generation program included in the symbol selecting program, thereby selecting a random number value. Further, this CPU 41 executes free games by a predetermined number of times based upon the selected random number value. After executing the future game process, the main CPU 41 executes coin payout, based upon the payout number of coins acquired in the future game process. After that, the main CPU 41 terminates this subroutine. In the future game process, the free game is carried out without inputting the number of BETs.
In a case where the main CPU 41 judges at step S19 that no scatter prize is established (S19: NO) and judges at step S21 that no special prize is established (S21: NO), it is determined to be “losing”, which does not come under any of the prizes. The word “losing” used herein denotes a case in which no coin payout is performed.
Next, a process of selecting symbols will be described with reference to
First, at step S31, the main CPU 41 executes a process of selecting a random number value. Specifically, the main CPU 41 selects five random number values corresponding to five symbol columns, respectively, from a numeric range between 0 and 255, by executing a random number generation program included in the symbol selecting program. The present embodiment describes a case of generating random numbers in a programmable fashion (a case of using so called software random numbers). In the present invention, however, a random number generator is provided, whereby random numbers may be sampled from the random number generator (so called hardware random numbers may be used).
Next, at step S32, the main CPU 41 determines code numbers of symbol columns (see
As described above, by the slot machine 10 and the playing method thereof according to this embodiment, the RAM 43 previously stores the BET information including the number of BETs placed in the previous game. In the next game, the main CPU 41 accepts input operation from the UTILITY button 200. The main CPU 41 then the auto-BET signal A1 and the auto-SPIN signal A2 output from the auto-BET circuit 210 and the auto-SPIN circuit 220, respectively, in accordance with the input operation made to the UTILITY button 200. Based upon the accepted auto-BET signal A1 and auto-SPIN signal A2 and the BET information concerning the previous game, stored in the RAM 43, the main CPU 41 automatically sets the number of BETs equal to that of BETs placed in the previous game while automatically rearranging the plural types of symbols in the display blocks 28, respectively. The UTILITY button 200 is configured to reciprocate in accordance with the input operation by the player. The auto-BET circuit 210 and the auto-SPIN circuit 220 are under open/closed control in accordance with the reciprocation of the UTILITY button 200 and in this manner, output the auto-BET signal A1 and the auto-SPIN signal A2, respectively.
Next, a game execution process according to another embodiment will be described with reference to
The game executed by the game execution process shown in
At step S40, the main CPU 41 judges whether or not the UTILITY button is in its ON state. Specifically, the main CPU 41 judges whether or not it receives the auto-BET signal A1 and the auto-SPIN signal A2 output in accordance with the input operation made to the UTILITY button 200. In a case where the main CPU 41 judges that the UTILITY button is in its ON state (S40: YES), the routine proceeds to step S41. In a case where the main CPU 41 judges that the UTILITY button is not in its ON state (S40: NO), the routine proceeds to step S102 at which the main CPU 41 judges whether or nor the BET switch is in its ON state. At step S102, in a case where the BET switch is in its ON state, processes at steps S103, S104, S105, and S106 similar to those at steps S3, S4, S5, and S6 of
Next, at step S41, the main CPU 41 executes a process of reading out the BET information concerning the previous game. Specifically, the main CPU 41 reads out the predetermined symbol on which the player placed BETs and the number of BETs stored in the RAM 43. The routine proceeds to step S42 at which the main CPU 41 reads the current credit amount out of the RAM 43 to judge whether or not the current credit amount is greater than or equal to the number of BETs placed in the previous game. In a case where the main CPU 41 judges that the current credit amount is greater than or equal to this number (S42: YES), the routine proceeds to step S44.
Next, at step S44, the main CPU 41 executes a process of determining a symbol as a BET object. Specifically, based upon the predetermined symbol on which the player placed BETs in the previous game, read out of the RAM 43 at step S41, the main CPU 41 determines as a BET object, the same symbol as the predetermined one on which the player placed BETs in the previous game.
Next, at step S45, the main CPU 41 executes a process of automatically setting the number of BETs. Specifically, based upon the auto-BET signal A1 received at step S40 and the number of BETs placed in the previous game read out of the RAM 43 at the step S41, the main CPU 41 automatically sets to place the number of BETs equal to that of BETs that the player placed in the previous game, on the predetermined symbol as the BET object determined at step S44.
Next, at step S47, the main CPU 41 executes a process of starting scroll-display. Specifically, the main CPU 41 automatically starts scroll-display of the plural types of symbols based upon the auto-SPIN signal A2 received at step S40.
Next, the routine proceeds to steps S48 and S49 at which the main CPU 41 executes the symbol selecting process and the symbol scroll-display stopping process. The routine proceeds to steps S50 and S52 at which the main CPU 41 then judges whether or not three or more symbols on which the player placed BETs from among the plural symbols displayed in a stopped manner on the respective blocks 28. In a case where a symbol on which the player placed BETs is the scatter symbol and the main CPU 41 judges that the three or more scatter symbols are displayed in a stopped manner, the routine proceeds to step S51 at which the main CPU 41 executes the coin payout process. In a case where a symbol on which the player placed BETs is the symbol “EARTH” as a trigger for the special prize and the main CPU 41 judges that the three or more symbols “EARTH” are displayed in a stopped manner, the routine proceeds to step S53 at which the main CPU 41 executes the future game execution.
In the above case, the main CPU 41 determines as the BET object, the symbol of the same type as that of the predetermined symbol on which the player placed BETs in the previous game included in the BET information, by referring to the BET information concerning the previous game, read out of the RAM 43, in the process of determining a symbol as the BET object at step S44. However, the present invention is not limitative thereto. For example, the main CPU 41 may determine at random a symbol of a different type from that of the predetermined symbol on which the player placed BETs in the previous game. In this case, at the next step, the main CPU 41 automatically sets to place the number of symbols equal to that of BETs placed in the previous game, on the determined different symbol.
Next, the game execution process according to yet another embodiment will be described by referring to
The game executed by the game execution process shown in
At step S60, the main CPU 41 judges whether or not the utility switch is in its ON state. Specifically, the main CPU 41 judges whether or not it receives the auto-SPIN signal A1 and the auto-SPIN signal A2 output in accordance with input operation made to the utility button 200. In a case where the main CPU 41 judges that the input operation has been made (S60: YES), the routine proceeds to step S61. In a case where the main CPU 41 judges that the utility switch is not in its ON state (S60: NO), the routine proceeds to step S112 at which the main CPU 41 judges whether or not the BET switch is in its ON state. At step S112, in a case where the BET switch is in its ON state, the main CPU 41 executes the steps S113, S114, S115, and S116 that are the same processes as those at steps S3, S4, S5, and S6.
Next, at step S61, the main CPU 41 executes a process of reading out the BET information concerning the previous game. Specifically, the main CPU 41 reads the predetermined payline on which the player placed BETs and the number of BETs stored in the RAM 43. The routine proceeds to the step S62 at which the main CPU 41 reads the current credit amount out of the RAM 43 to judge whether or not the current credit amount is greater than or equal to the number of BETs placed in the previous game read out at step S61. In a case where the main CPU 41 judges that the current credit amount is greater than or equal to the number of BETs (S62: YES), the routine proceeds to step S64.
Next, at step S64, the main CPU 41 executes a process of determining a payline on which BETs are to be placed, i.e., a payline as a BET object. Specifically, the main CPU 41 determines a payline of the same type as that of the predetermined payline on which the player placed BETs in the previous game, based upon the predetermined payline on which the player placed BETs in the previous game, read out of the RAM 43 at step S61.
Next, at step S65, the main CPU 41 executes a process of automatically setting the number of BETs. Specifically, the main CPU 41 automatically sets the number of BETs equal to that of BETs placed in the previous game, on the predetermined payline as the BET object determined at step S64, based upon the auto-BET signal A1 received at step S60 and the number of BETs which the player placed in the previous game, read out of the RAM 43 at step S61.
Next, at step S67, the main CPU 41 executes a process of automatically starting scroll-display. Specifically, the main CPU 41 automatically starts scroll-display of the plural types of symbols, based upon the auto-SPIN signal A2 received at step S60.
Next, the routine proceeds to steps S68 and S69 at which the main CPU 41 executes the symbol selecting process and a scroll-display stopping process. The routine then proceeds to steps S70 and S72 at which the main CPU 41 judges whether or not the plural types of symbols displayed in a stopped manner on the respective display blocks 28 include three or more symbols of the same type. In a case where the main CPU 41 judges that three or more scatter symbols of the same type are displayed in a stopped manner on the predetermined payline on which the player placed BETs, the routine proceeds to step S71 at which the main CPU 41 executes the coin payout process. In a case where the main CPU 41 judges that three or more symbols “EARTH” as a trigger for a special prize are displayed in a stopped manner on the predetermined payline on which the player placed BETs, the routine proceeds to step S73 at which the main CPU 41 executes a future game process.
In the above case, the main CPU 41 determines as the BET object, the payline of the same type as that of the predetermined one on which the player placed BETs in the previous game, information on which is included in the BET information, by referring to the BET information concerning the previous game, read out of the RAM 43 in the process of determining the payline as the BET object at step S64. However, the present invention is not limited thereto. For example, the main CPU may determine at random a payline of a different type from that of the predetermined payline on which the player placed BETs in the previous game. In this case, at the next step, the main CPU 41 automatically sets to place the number of BETs equal to that of BETs which the player placed in the previous game, on the determined different payline.
The above case described that the player performs input operation to the utility button 200 in each game. However, the present invention is not limitative thereto. For example, the utility button 200 may be automatically operated when the previous game is over. Further, automatic operation of the utility button 200 may be controlled only during a predetermined period of a game such as a special game. In a case where the automatic operation is made to the utility button 200, the automatic operation of the utility button 200 may be controlled until receipt of the input operation from the RESET operation 230.
The above case described that the main CPU 41 automatically sets, in a next game, a symbol or payline of a different type from that of the predetermined symbol or payline on which a player placed BETs in a previous game (steps S44 and S64). However, this invention is not limitative thereto. The main CPU 41 may determine the above-described process in a case where a predetermined condition is met. The predetermined condition is met when one of two conditions is met, in which one condition relates to the number of successive games executed upon operation to the utility button 200 and the other condition relates to a symbol changing mode set by a player.
The above case described that a combination of the plural symbols that forms a prize is based upon the number of symbols of the same type. However, the present invention is not limitative thereto. The plural types of symbols may form a combination.
While the above case described that a total of 15 symbols in 5 columns and 3 rows are displayed, the display format of symbols in the present invention is not limitative to that of 5 columns and 3 rows, and is applicable to a variety of display formats such as that of 3 columns and 3 rows. Further, while the above case described that symbols were displayed in a scrolling manner in each of the display block columns, each of these symbols may be individually displayed in a scrolling manner.
While the above case described that the symbols were displayed in a scrolling manner with the use of a liquid crystal display device or the like, the present invention is not limitative thereto. In a case where mechanical reels are employed, the symbols may be expressed and displayed on the surfaces thereof.
While the embodiment according to the present invention has been described, the description presents only some of the specific examples and is not intended to limit the present invention in any way and specific constructions of each means and the like can be properly changed in terms of design. Moreover, the effects described in the embodiment of the present invention are only the most preferable effects generated from the present invention and the effects to be caused by the present invention is not limitative thereto.
