This is a winning combination in which a predetermined dividend is awarded. The “white 7” symbol T2 is a symbol that can be handled as any of the five symbols “BAR” symbol T3, “bell” symbol T4, “watermelon” symbol T5, “plum” symbol T6, and “cherry” symbol T7. There is a so-called almighty design. As shown in FIG. 1, one “white” symbol T2 is arranged in each column of the first symbol arrangement table 34A and the third symbol arrangement table 34C, and two in each column of the second symbol arrangement table 34B. They are arranged one by one.

  As shown in FIGS. 6A, 6B, and 6C, the symbol lottery table is referred to when determining a scheduled symbol to be stopped and displayed in the middle of each display area of the main display 3 during the internal lottery process. It is a table. The symbol lottery table includes a first symbol lottery table, a second symbol lottery table, and a third symbol lottery table.

  The first symbol lottery table shown in FIG. 6 (a) is a symbol lottery table that is referred to in the normal game and draws seven types of symbols T1 to T7 arranged in the first symbol arrangement table 34A shown in FIG. is there. In the first symbol lottery table, the symbol winning probability is set based on the number of symbols T1 to T7 arranged in each column of the first symbol arrangement table 34A. For this reason, in the first symbol lottery table, the “black 7” symbol T1, the “white 7” symbol T2, and the “BAR” symbol T in the first symbol arrangement table 34A are displayed on one reel image on which 20 symbols are displayed. The winning probabilities of “Black 7” symbol T1, “White 7” symbol T2, and “BAR” symbol T are set to “1/20”, respectively. In the symbol arrangement table 34A, four or five symbols T4 to T7 are arranged for one reel image on which 20 symbols are displayed. Therefore, the winning probability of the symbols T4 to T7 is “4/20” or It is set to “5/20”. That is, the winning probability (“1/20”) of the “black 7” symbol T1, the “white 7” symbol T2, and the “BAR” symbol T is the winning probability (“4/20”, “5 /”) of the symbols T4 to T7. 20 "). As a result, in the normal game in which the symbol lottery table is used for the first symbol lottery table, the winning probability of the “black 7” symbol T1 that triggers the winning of the bonus game and the almighty “white 7” symbol T2 is relatively high. Is set low.

  The second symbol lottery table shown in FIG. 6B is a symbol lottery table which is referred to in the bonus game and lotters the six types of symbols T2 to T7 arranged in the second symbol arrangement table 34B. In the second symbol lottery table, the symbol winning probability is set based on the number of symbols T2 to T7 arranged in the second symbol arrangement table 34A. For this reason, in the second symbol lottery table, two “white 7” symbols T2 in the second symbol arrangement table 34B are arranged for one reel image on which 20 symbols are displayed. The winning probability of symbol T2 is set to “2/20”, and the winning probability of symbols T3 to T7 is set to the same rate as the winning probability of symbols T3 to T7 in the first symbol lottery table. That is, the winning probability (“2/20”) of the “white 7” symbol T2 is set higher than the winning probability (“1/20”) of the “BAR” symbol T3, and “ White 7 ”is set higher than the winning probability (“ 1/20 ”) of symbol T2. As a result, in the bonus game in which the symbol lottery table is used for the second symbol lottery table, the almighty “white 7” symbol T2 is frequently stopped and displayed in each display area, and the payout of symbols T2 to T7 is given to the player. The winning probability of the “white 7” symbol T2 is set to be higher than that of the base game so that the expected value for the game is high.

  The third symbol lottery table shown in FIG. 6C is a symbol lottery table that is referred to in the case of a special game and draws seven types of symbols T1 to T7 arranged in the third symbol arrangement table 34C. In the third symbol lottery table, the symbol winning probability is set based on the number of symbols T1 to T7 arranged in the third symbol arrangement table 34C. For this reason, in the third symbol lottery table, “black 7” symbol T1, symbol T4 and symbol T5 in the third symbol arrangement table 34C are arranged three by three for one reel image in which 20 symbols are arranged. Therefore, the winning probability of “Black 7” symbol T1, symbol T4 and symbol T5 is set to “3/20”, respectively, and the winning probability of symbol T2 and symbol T3, symbol T6 and symbol T7 is the first. It is set to the same rate as the winning probability of symbols T2 and T3, symbols T6 and T7 in one symbol lottery table. That is, the winning probability (“3/20”) of the “black 7” symbol T1 is set higher than the winning probability (“1/20”) of the “white 7” symbol T2 and the “BAR” symbol T3, and It is set higher than the winning probability (“1/20”) of the “black 7” symbol T1 in the first symbol lottery table. As a result, in the special game in which the symbol lottery table is used for the third symbol lottery table, the “black 7” symbol T1 that triggers the winning of the bonus game is frequently stopped and displayed in each display area to give a bonus to the player. The winning probability of the “black 7” symbol T1 is set to be higher than that of the normal game so that the expected value for winning the game is higher.

  As described above, in a special game where a game is played using the third symbol arrangement table 34C, the winning probability of the “black 7” symbol T1 that triggers the bonus game winning is played using the first symbol arrangement table 34A. Since the probability is set to be higher than that of the base game, a state in which the bonus game is continuously triggered (“retrigger”) during the special game that is performed after the bonus game ends is easy to win with high probability. Further, in the bonus game in which the game is played using the second symbol arrangement table 34B, the winning probability of the almighty “white 7” symbol T2 is set higher than that in the normal game, so that symbols T2 to T7 are displayed during the bonus game. It is easy to win with high probability. Thus, the slot machine 1 plays a game using the symbol arrangement tables 34A to 34C having different expected values for the player for each of the normal game, bonus game, and special game after the bonus game as the game mode. The game can be varied and the player's preference can be improved.

  The symbols to be stopped and displayed in the middle of each display area determined by referring to the first symbol lottery table, the second symbol lottery table, and the third symbol lottery table are stored in the symbol storage area of the RAM 33. .

  As shown in FIG. 7, the winning combination determining table is scheduled to stop and display in the middle of each display area determined with reference to the above-described first symbol lottery table, second symbol lottery table, and third symbol lottery table. It is a table referred when determining a winning combination based on a symbol. The winning combination determining table is also referred to when specifying the number of coins to be paid out according to the determined winning combination. In the internal lottery process, by referring to the winning combination determination table, for example, when five symbols T1 are combined in the middle of each display area along the active line as a combination of symbols, the winning combination is “black 7”. It is determined that the number of coins to be paid out is 100 (when the BET number is 1). The determined winning combination is stored in the winning combination storage area of the RAM 33, and the specified number of coins to be paid out is set in the payout number counter of the RAM 33.

  As shown in FIG. 8, the effect determination table is based on the effect identifiers A to R determined by the lottery and the scheduled stop symbols to be displayed in the middle of each display area stored in the winning storage area of the RAM 33. It is a table referred when determining an image, production sound, etc. When the production identifiers A to R corresponding to the scheduled stop symbols are determined by referring to the production determination table, the production image and production sound stored in correspondence with the production identifier are displayed on the main display 3 and the sub display 4. The sound is output to the speakers 12L, 12R, etc. for a predetermined production time. In addition, there may be no effect identifier in the effect identifiers of symbols T2 to T7 shown in the effect determination table, and when it is determined that there is no effect identifier by lottery, a prize is awarded to improve the interest of the player. There are cases where no production is performed.

  As shown in FIG. 9, the free game number lottery table is a table that is referred to when determining the number of free games to be executed in the bonus game. In this free game number lottery table, the number of free games is set to four stages of 5, 10, 15, and 20, and the number of times set in these four stages is a lottery process performed when a bonus game is won. Etc. are determined. The determined number of free games is set to the value of the free game counter in the RAM 33. Note that the number of free games is not limited to the above-described number, and can be set variously.

  Next, the above-mentioned main display 3 will be described in detail with reference to FIG. FIG. 10 is a diagram showing a display screen of the main display 3.

The character information display portion 83c displays character information indicating the current state of the game. For example, the game mode is changed from the normal game mode or the special game mode to the bonus game mode, and from the bonus game mode to the special game mode. Character information notifying the state of shifting to is displayed. The PAID number display portion 83d displays the number of coins that can be obtained in one game, and the charge display portion 83e displays the converted value of the number of credits for a predetermined fee.

  Next, the effective line of the slot machine 1 will be described with reference to FIG. 11A and 11B are diagrams for explaining an effective line of the slot machine. FIG. 11A shows an example of the effective line, and FIG. 11B shows another example of the effective line.

  As shown in FIG. 11A, the slot machine 1 has one effective line that is set to be activated when a coin is inserted, and this effective line is a middle symbol of each display area A to E. It is validated along the display areas A2, B2, C2, D2, E2.

  In the present embodiment, it has been described that the slot machine 1 sets one effective line along the middle of the display areas A to E. However, the present invention is not limited to this, and the slot machine 1 As shown in FIG. 11A, the machine 1 includes an effective line along the upper symbol display areas A1, B1, C1, D1, and E1 of the display areas A to E, and a lower line of the display areas A to E. Effective lines along the symbol display areas A2, B2, C2, D2, and E2, V-shaped effective lines along the symbol display areas A1, B2, C3, D2, and E1 of the display areas A to E, and each display area It is also possible to set an inverted V-shaped effective line along the symbol display areas A3, B2, C1, D2, and E3 of A to E, and four effective lines shown in FIG.

  When a plurality of valid lines are set, the number of valid lines is set to increase in accordance with the number of coins inserted by operating the player's BET buttons 9 and 10 or the like. Further, the number of effective lines is not limited to the number described above, and further effective lines can be set.

  In the slot machine 1, the winning determination is made by the main CPU 32 along the active line, with five identical symbols successively in the middle symbol display areas A2, B2, C2, D2, E2 of the display areas A to E. This is done depending on whether or not they are lined up. If the same symbol is stopped and displayed in the middle symbol display areas A2, B2, C2, D2, and E2 in the middle of each display area A to E along the active line, it is determined that the winning condition is satisfied. Based on the winning combination determination table (see FIG. 7), a payout corresponding to the combination of symbols is paid to the player.

  In the bonus game and the special game executed after the bonus game ends, a free game that can receive a coin payment without consuming coins or credits is executed a predetermined number of times.

  Hereinafter, the control process of the slot machine 1 described above will be described with reference to FIGS. In the drawings, step is abbreviated as S. The following processing is performed by the main CPU 32 executing programs stored in the ROM 34 and the RAM 33.

  The operation procedure of the main control process of the slot machine 1 will be described with reference to FIG. FIG. 12 is a main flowchart showing the operation procedure of the main control process of the slot machine 1. When the main CPU 32 starts the main control process as the system is activated, the main CPU 32 repeatedly executes each step from step S1 to step S9 sequentially.

  First, in step S1, the main CPU 32 performs an initialization process for starting the next slot game. This initialization process is a process for initializing data and the like of items set in a predetermined data area stored in the RAM 33, and is performed every time one slot game ends. In the initialization process of step S1, the main CPU 32 sets the symbol array table used for the game of the normal game in the first symbol array table 34A and controls the image control circuit 71 to control the first CPU during the normal game. Reel images R1 to R5 on which symbols T1 to T7 arranged in the symbol arrangement table 34A are drawn are displayed on display areas A to E of the main display 3. Next, the main CPU 32 sequentially performs a coin insertion process, an internal lottery process, a reel control process, and a payout number determination process from step S2 to step S5, and executes a slot game in the normal game mode.

  If the main CPU 32 determines in step S6 that the bonus game trigger is established during the normal game, the main CPU 32 proceeds to step S7. If the main CPU 32 determines that the bonus game trigger is not established, the main CPU 32 proceeds to step S9. The payout coins in the base game are paid out without executing the game process.

  In step S9, the main CPU 32 instructs the hopper drive circuit 63 to execute a coin payout process based on the value of the payout number counter specified in the payout number determination process. When the main CPU 32 executes coin payout processing in step S9 to end one game, the main CPU 32 returns to step S1 and prepares for starting the slot game in the next normal game.

  If the main CPU 32 determines in step S6 that the bonus game trigger is established during the normal game, the main CPU 32 proceeds to step S7, shifts the game mode from the normal game mode to the bonus game mode, and executes the bonus game mode slot game ( Free game). Subsequently, when the bonus game ends, the main CPU 32 proceeds to step S8, shifts the game mode from the bonus game mode to the special game mode, and executes the slot game (free game) in the special game mode.

  Subsequently, when the main CPU 32 determines that the bonus game trigger is not established during the special game (step S77: NO described later shown in FIG. 18), the main CPU 32 returns to step S1 and changes the game mode from the special game mode to the normal game mode. Process to move to. On the other hand, if the main CPU 32 determines that a bonus game trigger has been established during the special game (YES in step S77 shown in FIG. 18 to be described later), the main CPU 32 shifts the game mode from the special game mode to the bonus game mode, and A slot game in the game mode is executed (see step S78 described later shown in FIG. 18). Then, when the bonus game won during the special game is completed, a process of shifting to the special game mode is executed again.

  Next, coin insertion processing performed by the main CPU 32 will be described with reference to FIG. FIG. 13 is a flowchart showing the operation procedure of the coin insertion process.

  The main CPU 32 determines whether or not coin insertion has been detected based on whether or not a coin insertion signal is input from the inserted coin sensor 6a (step S11). The main CPU 32 proceeds to step S12 when coin insertion is detected, and proceeds to step S13 after executing step S12. On the other hand, the main CPU 32 proceeds to step S13 without executing step S12 when coin insertion is not detected. In step S12, the main CPU 32 updates a credit number counter indicating the balance of coins (credits) stored in the slot machine 1. At this time, the main CPU 32 adds according to the inserted coin. Subsequently, in step S13, the main CPU 32 determines whether or not the credit number counter is “0”. If it is “0”, the main CPU 32 proceeds to step S20. On the other hand, when the credit counter is not “0”, the main CPU 32 proceeds to step S14. In step S <b> 14, the main CPU 32 permits operation acceptance of the 1 BET button 9 and the maximum BET button 10.

  Next, in step S15, the main CPU 32 determines whether or not a BET operation has been detected by the 1BET button 9 and the maximum BET button 10, and if any operation is detected, the process proceeds to step S16, and any operation is performed. If not detected, the process proceeds to step S20. In step S16, the main CPU 32 updates the BET number counter and the credit number counter indicating the number of BETs of coins based on the BET button that has detected the operation (adds the BET number and subtracts the credit number counter). Next, in step S17, the main CPU 32 determines whether or not the BET number counter is maximum. If the BET number counter is maximum, the main CPU 32 proceeds to step S18, performs processing for prohibiting updating of the BET number counter, and proceeds to step S19. On the other hand, if the BET number counter is not the maximum, the main CPU 32 proceeds to step S19 without executing step S18. In step S <b> 19, the main CPU 32 permits the operation reception of the spin button 8.

  Next, in step S20, the main CPU 32 determines whether or not the operation of the spin button 8 is detected. When the operation of the spin button 8 is detected, the coin insertion process is terminated, and the main flowchart shown in FIG. The process proceeds to the internal lottery process (step S3). In step S20, when the player does not operate the spin button 8, the processes in steps S11 to S20 described above are repeated.

  Next, an internal lottery process performed by the main CPU 32 will be described with reference to FIG. FIG. 14 is a flowchart showing the operation procedure of the internal lottery process. The internal lottery process is performed when a signal is input from the spin switch 8a.

  In step S31, the main CPU 32 issues an instruction to the sampling circuit 36, and extracts an arbitrary random number value from the random numbers generated by the random number generator 35. Next, in step S32, the main CPU 32 refers to the symbol lottery table (see FIG. 6) stored in the ROM 34 based on the random number value extracted in step S31, and the middle symbol of each display area A to E. The symbols to be stopped and displayed in the display areas A2, B2, C2, D2, and E2 (scheduled symbols to be stopped) are determined. In this case, random number random determination is performed five times corresponding to the middle symbol display areas A2, B2, C2, D2, and E2 of the display areas A to E, and the symbols to be stopped are also determined for the display areas A to E. This is performed five times corresponding to the middle symbol display areas A2, B2, C2, D2, and E2.

  In step S <b> 32, the main CPU 32 determines the symbol to be stopped to be stopped in the middle of the display areas A to E, and then stores the symbol data of the determined symbol to be stopped in the symbol storage area of the RAM 33. The main CPU 32 performs stop display of symbols in the display areas A to E based on the symbol data stored in the symbol storage area.

  In step S33, the main CPU 32 refers to the winning combination determination table (see FIG. 7) by using the symbol data of the symbols scheduled to stop in the middle of the display areas A to E stored in the symbol storage area of the RAM 33. The winning combination is determined from each. When the winning combination is determined, the main CPU 32 ends the internal lottery process and proceeds to the reel control process of the main flowchart shown in FIG. 12 (step S4).

  Next, the reel control process performed by the main CPU 32 will be described with reference to FIG. FIG. 15 is a flowchart showing the operation procedure of the reel control process.

  In step S41, the main CPU 32 performs control processing for the reel images R1 to R5. At this time, the main CPU 32 instructs the image control circuit 71 to rotate and display the reel images R1 to R5 in the display areas A to E of the main display 3. The main CPU 32 controls the image control circuit 71 to perform image processing so that a plurality of types of symbols arranged in the symbol arrangement tables 34A to 34C appear to the player as if the mechanical reels are rotated.

  The main CPU 32 rotates and displays the reel images R1 to R5 in the display areas A to E of the main display 3 in step S41, and then proceeds to step S42 to set a predetermined time after the reel images R1 to R5 are rotated and displayed. It is determined whether the value of the reel rotation stop timer is “0”. When the main CPU 32 determines that the value of the reel rotation stop timer is “0”, the process proceeds to step S43. When the main CPU 32 determines that the value of the reel rotation stop timer is not “0”, the value of the reel rotation stop timer is “0”. Wait until it reaches 0 ”. Subsequently, in step S43, the main CPU 32 instructs the image control circuit 71 to sequentially stop and display the reel images R1 to R5 so that all the reel images R1 to R5 stop in the display areas A to E. When the main CPU 32 executes the stop processing of the reel images R1 to R5 in step S43, the reel control processing ends, and the process proceeds to a payout number determination process shown in FIG. 12 (step S5).

  Next, the payout number determination process performed by the main CPU 32 will be described with reference to FIG. FIG. 16 is a flowchart showing the operation procedure of the payout number determination process.

  In step S51, the main CPU 32 determines the number of coins to be paid out by referring to the winning combination determination table (see FIG. 7) based on the winning combination determination result of the internal lottery process.

  Subsequently, in step S52, the main CPU 32 adds the coin payout number determined in step S51 to the payout number counter and ends the payout number determination process.

  Next, bonus game processing performed by the main CPU 32 will be described with reference to FIG. If it is determined in step S6 that the bonus game trigger has been established, the main CPU 32 proceeds to step S7 in FIG. 12, and performs bonus game processing. FIG. 17 is a flowchart showing the operation procedure of the bonus game process.

  In step S61, during the normal game, the main CPU 32 stops and displays “Black 7” symbol T1 in the middle of each display area A to E along the active line, and determines the transition condition to the bonus game. If it is determined that it is satisfied, the bonus game flag is set to “ON”. In addition, the main CPU 32 changes the symbol arrangement table used for the bonus game from the first symbol arrangement table 34A to the second symbol arrangement table 34B in which many “white 7” symbols T2 are arranged. By controlling the circuit 71, the reel images R1 to R5 on which the symbols T2 to T7 arranged in the second symbol arrangement table 34B are drawn are displayed in the display areas A to E of the main display 3 during the bonus game.

  Subsequently, in step S62, the main CPU 32 determines the number of free games to be executed during the bonus game mode based on the free game number lottery table (see FIG. 9) by lottery processing. Here, in the bonus game, the free game is played, for example, 10 times as the first game number. In step S63, the main CPU 32 sets the value (for example, 10) of the number of free games determined by the lottery process to the value of the free game number counter.

  Subsequently, the main CPU 32 executes an internal lottery process, a reel control process, and a payout number determination process from step S64 to step S66 so as to play a free game based on the value of the specified free game number counter. The processing from step S64 to step S66 is performed according to the flowcharts shown in FIGS. 14, 15, and 16 described above.

  Next, in step S67, the main CPU 32 determines whether or not the value of the free game number counter is “0”. If the main CPU 32 determines that the value of the free game number counter is “0”, the process proceeds to step S69. If it is determined that the value of the free game number counter is not “0”, the processes of steps S64 to S67 are repeatedly executed until the value of the three game number counter becomes “0”.

  In step S69, the main CPU 32 sets the bonus game flag to “OFF” when the value of the free game number counter becomes “0”. Then, when executing the process of step S69, the main CPU 32 ends the bonus game process and proceeds to the special game process of the main flowchart shown in FIG. 12 (step S8).

Next, the special game process performed by the main CPU 32 will be described with reference to FIG. FIG. 18 is a flowchart showing the operation procedure of the special game process.

  In step S71, the main CPU 32 sets the special game flag to “ON” on condition that the bonus game has ended. Further, the main CPU 32 changes the symbol arrangement table used for the special game game from the second symbol arrangement table 34B to the third symbol arrangement table 34C in which many “black 7” symbols T1 that trigger the bonus game are arranged. By controlling the image control circuit 71, the reel images R1 to R5 on which the symbols T1 to T7 arranged in the third symbol arrangement table 34C are drawn are displayed in the display areas A to E of the main display 3 during the special game. To do.

  Next, in step S72, the main CPU 32 determines the number of free games to be executed in the special game based on the number of payouts acquired during the bonus game. More specifically, the main CPU 32 determines the number of free games to be executed in the special game mode with reference to the free game number lottery table (see FIG. 9) based on the value of the payout number counter in the RAM 33 after the bonus game ends. To do. The number of free games is determined so that, for example, the number of free games increases as the total number of coins acquired during the bonus game increases. In step S73, the main CPU 32 sets the number of free games (for example, 5) determined based on the value of the payout number counter in the free game number counter. Here, in the special game, the free game is played as the second number of games, for example, five times.

  Subsequently, the main CPU 32 executes an internal lottery process from step S74 to step S76, a reel control process, and a payout number determination process so as to play a free game based on the value of the specified free game number counter. The processing from step S74 to step S76 is performed according to the flowcharts shown in FIGS. 14, 15, and 16 described above.

  Next, in step S77, in the free game executed during the special game, the main CPU 32 stops and displays five “black 7” symbols T1 in the middle of the display areas A to E along the active line. Then, it is determined whether or not a bonus game trigger is established. If it is determined that a bonus game trigger is established, the process proceeds to step S78. If it is determined that a bonus game trigger is not established, the process proceeds to step S79.

  In step S78, the main CPU 32 determines that a bonus game trigger has been established, and executes bonus game processing. At this time, the main CPU 32 changes the symbol arrangement table used for the bonus game from the third symbol arrangement table 34C to the second symbol arrangement table 34B in which many “white 7” symbols T2 are arranged. By controlling the control circuit 71, the reel images R1 to R5 on which the symbols T2 to T7 arranged in the second symbol arrangement table 34B are drawn are displayed in the display areas A to E of the main display 3 during the bonus game. The process of step S78 is processed by the main CPU 32 according to the flowchart shown in FIG. When the bonus game process ends in step S78, the main CPU 32 returns to step 71 and repeats the processes of steps S71 to S77 of the special bonus game process again.

  In step S79, the main CPU 32 subtracts “1” from the value of the free game number counter in the RAM 33.

  Subsequently, in step S80, the main CPU 32 determines whether or not the value of the free game number counter is “0”. If it is determined that the value of the free game number counter is “0”, the main CPU 32 proceeds to step S81. If it is determined that the value of the free game number counter is not “0”, the processes of steps S74 to S80 are repeatedly executed until the value of the three game number counter becomes “0”.

  Next, in step S81, the main CPU 32 sets the special game flag to “OFF” when the value of the free game number counter becomes “0”. Then, when executing the process of step 82, the main CPU 32 ends the special game process and proceeds to the coin payout process of the main flowchart shown in FIG. 12 (step S9).

  When the special game process in step S8 ends, the main CPU 32 proceeds to step S9, and totals the coins acquired in the normal game process (steps S2 to S5), the bonus game process (step S7), and the special game process (step S8). Based on the value of the number-of-payout counter in the RAM 33 for which the number of sheets has been counted, a coin payout process is executed to end the game.

  When the main CPU 32 finishes the coin payout process in step S9, the main CPU 32 returns to step S1 and executes the initialization process to the normal game mode. In the initialization process after the end of the special game, the main CPU 32 uses the symbol arrangement table used for the game of the base game as the third symbol arrangement from the third symbol arrangement table 34C to the “black 7” symbol T1 that triggers the bonus game. By changing to the first symbol arrangement table 34A arranged less than the table 34C and controlling the image control circuit 71, the symbols T1 to T7 arranged in the first symbol arrangement table 34A are drawn during the normal game. The reel images R1 to R5 are displayed in the display areas A to E of the main display 3.

  The preferred embodiment of the present invention has been described in detail above, but the gaming machine according to the present invention is not limited to the above-described embodiment, and is within the scope of the gist of the present invention described in the claims. Various modifications and changes are possible. For example, the present invention can be implemented in various forms as follows.

  In the above-described embodiment, the plurality of symbol arrangement tables 34A to 34C are selectively used according to the game mode of the slot game (normal game, bonus game, special game), but the plurality of symbol arrangement tables 34A to 34C are predetermined. If these conditions are satisfied, they can be used properly regardless of the situation. For example, in the normal game and the bonus game, when symbols T1 to T7 are displayed in a predetermined combination or a predetermined number in the symbol display areas A1 to E3, the first symbol is not changed without changing the game mode of the slot game. The arrangement table 34A or the second symbol arrangement table 34B may be changed to the third symbol arrangement table 34C or the like. Thereby, not only a special game but also a normal game and a bonus game can be set to change the player's expectation during the game.

  In the above-described embodiment, the special game is automatically started on the condition that the bonus game ends. However, the special game is based on, for example, the number of payouts obtained in the bonus game. It can also be started after the game is over. In addition, the special game can be started not only immediately after the bonus game is ended but also after the bonus game is ended and the game mode is temporarily changed to the normal game and a predetermined period has elapsed.

  In the above-described embodiment, the symbol arrangement of the plurality of symbol arrangement tables 34A to 34C is changed for all of the plurality of reel images R1 to R5, but the symbols of the plurality of symbol arrangement tables 34A to 34C are used. The arrangement can be changed for any of the plurality of reel images R1 to R5, and can also be performed for two or more of the plurality of reel images R1 to R5.

  Furthermore, in the above-described embodiment, when five “black 7” symbols T1 serving as a trigger for winning the bonus game are continuously displayed in the middle of the display areas A to E along the active line, The mode is shifted from the normal game mode or the special game mode to the bonus game mode. However, when the “black 7” symbol T1 is displayed in any of the display areas A to E, or the “black 7” symbol T1. The game mode can be shifted to the bonus game mode when a predetermined number of “white 7” symbols T2 are displayed in the display areas A to E. Further, as a condition for shifting to the bonus game mode, the transition from the normal game mode and the transition from the special game mode can be performed under different conditions such as changing the number of “black 7” symbols T1 displayed. For example, when “5” symbols T1 are displayed in the display areas A to E, the normal game mode is shifted to the bonus game mode, and the “black 7” symbol T1 is “3” in the display areas A to E. When the message is displayed, the special game mode is shifted to the bonus game mode.

  Further, in the above-described embodiment, three “black 7” symbols T1 that serve as a trigger for winning the bonus game are arranged in the symbol sequence of the third symbol array table 34C in each of the reel images R1 to R5. The number of “black 7” symbols T1 in the symbol array of the three symbol array table 34C can be variously changed. In the above-described embodiment, a plurality of symbol lottery tables shown in FIG. 6, a winning combination determining table shown in FIG. 7, an effect determining table shown in FIG. 8, a winning probability shown in the free game number lottery table shown in FIG. The numerical values and the like are not limited to the illustrated numerical values and can be variously changed.

  Furthermore, in the above-described embodiment, the number of free games played during the bonus game is determined by lotting the number of times set in the free game number lottery table by random number processing. The number of times can be determined by lottery according to various modes, and may be a predetermined number of games regardless of lottery.

  In the above-described embodiment, the number of free games in the special game is determined according to the payout obtained during the bonus game. However, the present invention is not limited to this, and the number of free games in the special game. Can be determined by various modes such as lottery by random lottery, or may be a predetermined number of games regardless of lottery or the like.

  Furthermore, in the above-described embodiment, the five reel images R1 to R5 and the display areas A to E corresponding thereto are used. However, the present invention is not limited to this, and the reel image and the display corresponding to the reel image are displayed. The number of areas can be variously changed. Furthermore, in the above-described embodiment, the display areas A to E are provided on the main display 3, but it is also possible to provide a display area on the sub display 4 or the like to display a reel image related to the slot game.
