[1] Main Processing FIG. 28 shows the main processing executed by the CPU 41 of the main control circuit 40 when the power is turned on. When the power is turned on, the CPU 41 stores the registers and PIOs (parallel input / output ports) in step S1. Initialize each one. In step S2, the pending data storage unit 101, special symbol storage unit 102, flag storage unit 103, timer storage unit 104, and counter storage unit 105 of the RAM 43 are initialized, and a timer interrupt is generated every 4 msec in step S3. The CTC (counter / timer) is initialized as described above.

When CPU 41 initially sets CTC in step S3, CPU 41 transmits a reserved symbol command C001 (h) to effect control circuit 60 in step S4. The hold symbol command C001 (h) notifies the effect control circuit 60 that the normal hold symbol 34 is displayed when the hold command is received, and the CPU 41 notifies the effect control circuit 60 of the hold symbol command C001 in step S4. If (h) is transmitted, the counter update process 1 in step S5 is repeated. This counter update processing 1 is to update each of the random counter MR2 and the random counter MR4 of the counter storage unit 105 by a predetermined unit value “1” recorded in advance in the ROM 42, and the random counter MR2 of the counter storage unit 105 Each of the random counters MR4 is initially set to the lower limit value “0” in step S2, and the random counter MR2 is added from the lower limit value “0” to the upper limit value “1000” in step S5 and then returned to the lower limit value “0”. In step S5, the random counter MR4 is added from the lower limit value “0” to the upper limit value “32” and then returned to the lower limit value “0” to be added cyclically.
[2] Timer Interrupt Processing FIG. 29 shows timer interrupt processing executed by the CPU 41 every 4 msec when a timer interrupt occurs. The CPU 41 performs input processing at step S11 and counter update processing 2 at step S12 each time a timer interrupt occurs. The data acquisition process in step S13 and the process process in step S14 are executed in this order.
[2-1] Input Processing FIG. 30 shows the input processing in step S11, and the CPU 41 determines whether or not a start signal is output from the sensor circuit 44 in step S21. If it is determined that the start signal is not output from the sensor circuit 44, the start signal flag in the flag storage unit 103 is reset to an OFF state in step S22, and the start signal is output from the sensor circuit 44 in step S21. If it is determined that the start signal flag is ON, the start signal flag of the flag storage unit 103 is set to ON in step S23. The start signal flag is initially set to the off state in step S2, and is set to the on state when the game ball wins in the start port 23.
[2-2] Counter update process 2
The counter update process 2 in step S12 of FIG. 29 is to update each of the random counter MR1 and the random counter MR3 of the counter storage unit 105 by a certain unit value “1”. Each of the random counter MR1 and the random counter MR3 is initially set to the lower limit value “0” in step S2, and the random counter MR1 is changed from the lower limit value “0” to the upper limit value “100” in the counter update process 2 in step S12. Is added to the lower limit value “0” and then cyclically added, and the random counter MR3 is added from the lower limit value “0” to the upper limit value “62” in the counter update process 2 in step S12, and then the lower limit value. It is cyclically added back to “0”.
[2-3] Data Acquisition Process FIG. 31 shows the data acquisition process in step S13, and the CPU 41 determines whether or not the start signal flag of the flag storage unit 103 is set to the on state in step S31. If it is determined that the start signal flag of the flag storage unit 103 is set to the ON state, the update result of the random counter MR1, the update result of the random counter MR2, the update result of the random counter MR3, and the random counter MR3 from the counter storage unit 105 in step S32. Each of the update results is detected, and it is determined in step S33 whether or not the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 with the hold number 1.

  If the CPU 41 determines in step S33 that the random data MR1 to the random counter MR3 are not recorded in the reserved data storage unit 101 of the reserved number 1, the detection result of the random counter MR1, the detection result of the random counter MR2, and the random counter are determined in step S34. Each detection result of MR3 is recorded in the hold data storage unit 101 of the hold number 1. Then, in step S35, a hold command A001 (h) is transmitted to the effect control circuit 60 to notify that one special symbol game has been held, and in step S46, the start signal flag of the flag storage unit 103 is turned off. Set.

  If the CPU 41 determines in step S33 that the random counter MR1 to random counter MR3 are recorded in the reserved data storage unit 101 with the holding number 1, the random counter MR1 to random counter MR1 is stored in the holding data storage unit 101 with the holding number 2 in step S36. It is determined whether MR3 is recorded. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 of the hold number 2, the process proceeds to step S37, and the detection result of the random counter MR1 and the detection result of the random counter MR2 Each detection result of the random counter MR3 is recorded in the hold data storage unit 101 of the hold number 2. Then, it is determined whether or not the game mode is changed from the normal hold mode to the special hold mode in the special hold mode changing process in step S38, and a hold command “A002 (h)” is transmitted to the effect control circuit 60 in step S39. Thus, it is notified that the two special symbol games have been suspended, and the start signal flag of the flag storage unit 103 is set to the OFF state in step S48.

  FIG. 32 shows the special hold mode change process in step S38, and the CPU 41 determines whether or not the special hold symbol flag in the flag storage unit 103 has been reset to the off state in step S51. The special reserved symbol flag in the flag storage unit 103 is initially set to the off state in step S2, and is displayed when the special symbol game is suspended by setting the game mode to the normal hold mode when the power is turned on. A normal reserved symbol 34 is displayed in the reserved area 33 of the symbol display 32.

  If the CPU 41 determines in step S51 that the special reserved symbol flag in the flag storage unit 103 is set to the OFF state, the detection result of the random counter MR1 is compared with the jackpot look-ahead value (7) recorded in advance in the ROM 42 in step S52. To do. The detection result of the random counter MR1 is the one detected in the immediately preceding step S32. If the CPU 41 determines in step S52 that the detection result of the random counter MR1 is the same as the jackpot look-ahead value, the CPU 42 displays the result from the ROM 42 in step S53. The reserved symbol determination table 1 of 20 (a) is detected, and the update result of the random counter MR4 is detected from the counter storage unit 105 in step S54.

  When the CPU 41 detects the update result of the random counter MR4 in step S54, the CPU 41 selects a determination result corresponding to the detection result of the random counter MR4 from the reserved symbol determination table 1 in step S55, and whether the determination result is changed in step S56. Judge whether or not. If it is determined that the determination result is changed, the reserved symbol command C002 (h) is transmitted to the effect control circuit 60 in step S57, and the special reserved symbol flag in the flag storage unit 103 is turned on in step S58. By setting, the game mode is changed from the normal hold mode to the special hold mode, and in step S59, the minimum continuation number (3) recorded in advance in the ROM 42 is set in the counter MN1 of the counter storage unit 105. This counter MN1 is set to the initial value (0) recorded in advance in the ROM 42 in step S2. That is, when the random data MR1 determined to be a big hit in either the off state or the on state of the probability variation mode is recorded in the hold data storage unit 101 of the latest hold number 2, it is determined in advance. The game mode is changed from the normal hold mode to the special hold mode with a certain high probability, and the minimum continuation count (3) is set in the counter MN1.

  When the CPU 41 determines in step S52 that the detection result of the random counter MR1 is different from the jackpot look-ahead value, in step S60, the nine random change values (17, 27) recorded in advance in the ROM 42 are the detection results of the random counter MR1. , 37, 47, 57, 67, 77, 87, 97). Each of these nine probability change dedicated values (17 to 97) is a value determined to be a big hit in the on state of the probability variation mode and determined to be off in the off state of the probability variation mode. If it is determined in S60 that the detection result of the random counter MR1 is different from any of the nine probability change dedicated values (17 to 97), the process proceeds to step S61.

  When proceeding to step S61, the CPU 41 determines whether or not the detection result of the random counter MR2 at the immediately preceding step S32 is a value within the prefetch range (301 to 500) recorded in advance in the ROM. This pre-reading range (301 to 500) is a range (301 to 400) for selecting a bath start fluctuation start command 80014h at the time of determination of detachment, and a selection start of fluctuation reach command 80015h for determination of detachment. When the CPU 41 determines in step S61 that the detection result of the random counter MR2 is a value within the prefetch range (301 to 500), the CPU 41 displays the range from the ROM 42 in step S62. The reserved symbol determination table 2 of 20 (b) is detected, and the update result of the random counter MR4 is detected from the counter storage unit 105 in step S63.

  When the CPU 41 detects the update result of the random counter MR4 in step S63, the CPU 41 selects a determination result corresponding to the detection result of the random counter MR4 from the reserved symbol determination table 2 in step S64, and whether the determination result is changed in step S65. Judge whether or not. If it is determined that the determination result is changed, the reserved symbol command C002 (h) is transmitted to the effect control circuit 60 in step S66, and the special reserved symbol flag in the flag storage unit 103 is turned on in step S67. By setting, the game mode is changed from the normal hold mode to the special hold mode, and the minimum continuation count (3) is set in the counter MN1 of the counter storage unit 105 in step S68. That is, when a random counter MR1 that is determined to be out of the probability variation mode in either the off state or the on state is recorded in the hold data storage unit 101 of the latest hold number 2, the latest hold number is recorded. When the random counter MR2 for bath reach or the random counter MR2 for proposal reach is recorded in the hold data storage unit 2 of 2, the game mode is changed from the normal hold mode to the special hold mode with a predetermined low probability. The minimum number of continuations (3) is set in the counter MN1.

  If the CPU 41 determines in step S36 in FIG. 31 that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 2, the random counter MR1 is stored in the hold data storage unit 101 of the hold number 3 in step S40. Determine whether or not the random counter MR3 is recorded. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 of the hold number 3, the process proceeds to step S41, and the detection result of the random counter MR1 and the detection result of the random counter MR2 Each detection result of the random counter MR3 is recorded in the hold data storage unit 101 of the hold number 3. Then, it is determined whether or not the game mode is changed from the normal hold mode to the special hold mode in the special hold mode change process in step S42, and the hold command “A003 (h)” is transmitted to the effect control circuit 60 in step S43. In this way, it is notified that the special symbol game has been suspended three times, and the start signal flag of the flag storage unit 103 is reset to the OFF state in step S48.

  FIG. 32 shows the special hold mode change process in step S42. In the special hold mode change process in step S42, the minimum continuation count (4) is set in the counter MN1 of the counter storage unit 105 in steps S59 and S68. This is different from the special hold mode changing process in step S38. That is, when a random counter MR1 that is determined to be a big hit in either the off state or the on state of the probability variation mode is recorded in the hold data storage unit 101 of the latest hold number 3, a certain high probability The game mode is changed from the normal hold mode to the special hold mode, and the minimum continuation count (4) is set in the counter MN1. When a random counter MR1 that is determined to be out of the probability change mode in either the off state or the on state is recorded in the hold data storage unit 101 of the latest hold number 3, the latest hold number 3 When a random counter MR2 for bath reach or a random counter MR2 for proposal reach is recorded in the hold data storage unit 101, the game mode is changed from the normal hold mode to the special hold mode with a certain low probability, and the counter MN1 The minimum number of continuations (4) is set.

  If the CPU 41 determines in step S40 in FIG. 31 that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 3, the random counter MR1 is stored in the hold data storage unit 101 of the hold number 4 in step S44. Determine whether or not the random counter MR3 is recorded. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 with the hold number 4, the process proceeds to step S45, and the detection result of the random counter MR1 and the detection result of the random counter MR2 Each detection result of the random counter MR3 is recorded in the hold data storage unit 101 of the hold number 4. Then, it is determined whether or not the game mode is changed from the normal hold mode to the special hold mode in the special hold mode changing process in step S46, and the hold command 1 “A004 (h)” is transmitted to the effect control circuit 60 in step S47. By doing so, it is notified that four special symbol games have been put on hold, and in step S48, the start signal flag of the flag storage unit 103 is reset to the off state.

  FIG. 32 shows the special hold mode change process in step S46, and the special hold mode change process in step S46 sets the minimum number of continuations (5) in the counter MN1 of the counter storage unit 105 in each of steps S59 and S68. This is different from the special hold mode changing process in step S38. That is, when a random counter MR1 that is determined to be a big hit is recorded in the hold data storage unit 101 of the latest hold number 4 in either the off state or the on state of the probability variation mode, a certain high probability Thus, the game mode is changed from the normal hold mode to the special hold mode, and the minimum continuation count (5) is set in the counter MN1. When a random counter MR1 that is determined to be out of the probability variation mode in either the off state or the on state is recorded in the hold data storage unit 101 of the latest hold number 4, the latest hold number 4 When a random counter MR2 for bath reach or a random counter MR2 for proposal reach is recorded in the hold data storage unit 101, the game mode is changed from the normal hold mode to the special hold mode with a certain low probability, and the counter MN1 The minimum number of continuations (5) is set.

If the CPU 41 determines in step S44 in FIG. 31 that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 with the hold number 4, the detection result of the random counter MR1 and the detection result of the random counter MR2 in step S49. And the detection result of the random counter MR3 are cleared, and the start signal flag of the flag storage unit 103 is reset to the OFF state in step S48. In other words, the upper limit value “4 times” is set for the number of times that the special symbol game is held, and if the game ball wins in the start port 23 in a state where the special symbol game is already held four times, it is random. Neither recording processing of the counter MR1 to random counter MR3 nor transmission processing of the hold command is performed.
[2-4] Process Processing FIG. 33 shows the process processing in step S14. This process includes a big hit determination process in step S81, a fluctuation start process in step S82, a fluctuation process in step S83, a fluctuation stop process in step S84, a standby process in step S85, and a big hit game process in step S86. The jackpot determination process in step S81 to the jackpot game process in step S86 are alternatively performed according to the setting state of the process flag in the flag storage unit 103.
[2-4-1] Big hit determination process FIG. 34 is a big hit determination process in step S81. This jackpot determination process is executed when the process flag in the flag storage unit 103 is set to (0), and the process flag in the flag storage unit 103 is initialized to (0) in step S2.

  In step S91, the CPU 41 determines whether or not the random counter MR1 is recorded in the hold data storage unit 101 with the hold number 1. If it is determined that the random counter MR1 is recorded in the hold data storage unit 101 with the hold number 1, the process proceeds to step S92, and the random counter MR1 is detected from the hold data storage unit 101 with the hold number 1. Then, the process proceeds to step S93, and it is determined whether or not the probability variation flag of the flag storage unit 103 is set to the on state. This probability variation flag is initially set to the off state in step S2, and the probability variation mode is set to the off state when the power is turned on.

  If the CPU 41 determines in step S93 that the probability variation flag of the flag storage unit 103 is set to the on state, it detects the big hit determination table 2 of FIG. 15B from the ROM 42 in step S94. In step S96, a determination result corresponding to the detection result of the random counter MR1 is selected from the big hit determination table 2. In step S97, it is determined whether or not the determination result is a big hit. If the CPU 41 determines in step S93 that the probability variation flag of the flag storage unit 103 has been reset to the OFF state, it detects the big hit determination table 1 in FIG. 15A from the ROM 42 in step S95. In step S96, a determination result corresponding to the detection result of the random counter MR1 is selected from the big hit determination table 1, and in step S97, it is determined whether or not the determination result is a big hit.

  If the CPU 41 determines that the determination result is out of step S97, the CPU 41 resets the big hit flag in the flag storage unit 103 to the OFF state in step S104. The big hit flag in the flag storage unit 103 is initially set to the off state in step S2. When the CPU 41 resets the big hit flag in the flag storage unit 103 to the off state in step S104, the special bonus flag is read from the ROM 42 in step S105. The off symbol (1) is selected as the symbol. In step S102, the selection result of the special symbol is recorded in the special symbol storage unit 102, and (1) is set in the process flag of the flag storage unit 103 in step S103.

When the CPU 41 determines that the determination result is a big hit in step S97, the big hit flag in the flag storage unit 103 is set to an on state in step S98. Then, in step S99, the random counter MR3 is detected from the hold data storage unit 101 with the hold number 1, and in step S100, the special symbol selection table shown in FIG. In step S101, a special symbol corresponding to the detection result of the random counter MR3 is selected from the special symbol selection table. In step S102, the special symbol selection result is recorded in the special symbol storage unit 102. In step S103, the flag storage unit 103 is recorded. (1) is set in the process flag.
[2-4-2] Change Start Processing FIG. 35 shows the change start processing in step S82. This variation start process is executed when the process flag of the flag storage unit 103 is set to (1), and the CPU 41 obtains the random counter MR2 from the hold data storage unit 101 with the hold number 1 in step S111. In step S112, the result of recording the special symbol in the special symbol storage unit 102 is compared with each of the normal jackpot symbol (3) and the probability variation jackpot symbol (7). If it is determined that the recording result of the special symbol in the special symbol storage unit 102 is either the normal jackpot symbol (3) or the probable variation jackpot symbol (7), the ROM 42 in FIG. The variation start command table 1 is detected, and in step S114, a variation start command corresponding to the detection result of the random counter MR2 is selected from the variation start command table 1. In step S115, a variation display time corresponding to the selection result of the variation start command is selected from the variation start command table 1, and in step S116, the variation display time selection result is set as an initial value in the timer MT1 of the timer storage unit 104. .

  When the recording result of the special symbol in the special symbol storage unit 102 is out of the design (1), the CPU 41 determines that the recording result of the special symbol in the special symbol storage unit 102 is the normal jackpot symbol (3) and the probable big hit symbol (in step S112). 7), the fluctuation start command table 2 of FIG. 18B is detected from the ROM 42 in step S117, and the detection result of the random counter MR2 is detected from the fluctuation start command table 2 in step S118. Select the change start command. In step S119, the variation display time corresponding to the selection result of the variation start command is selected from the variation start command table 2, and the selection result of the variation display time is set as an initial value in the timer MT1 of the timer storage unit 104 in step S120. .

  When CPU 41 initially sets timer MT1 of timer storage unit 104 in step S116 or step S120, CPU 41 transmits the selection result of the change start command to effect control circuit 60 in step S121. Then, the symbol information command is set in step S122, and the symbol information command setting result is transmitted to the effect control circuit 60 in step S123. The symbol information command setting process is performed in accordance with the recording result of the special symbol in the special symbol storage unit 102. If the symbol (1) is recorded in the special symbol storage unit 102, the symbol information command is set. When 9001 (h) is set and the normal big hit symbol (3) is recorded in the special symbol storage unit 102, the symbol information command 9003 (h) is set, and the special symbol big hit symbol (7 ) Is recorded, a symbol information command 9007 (h) is set.

  When the CPU 41 transmits the setting result of the symbol information command in step S123, the CPU 41 proceeds to the normal hold mode return process in step S124. This normal hold mode return processing is to determine whether or not to return the game mode from the special hold mode to the normal hold mode when the game mode is set to the special hold mode. When the return processing is completed, the random counter MR1, the random counter MR2, and the random counter MR3 are cleared from the hold data storage unit 101 of the hold number 1 in step S125, and the hold data storage unit 101 of the hold number 2 is stored in step S126. It is determined whether or not random counter MR1 to random counter MR3 are recorded. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 with the hold number 2, the process proceeds to step S132, and (2) is set in the process flag of the flag storage unit 103. .

  If the CPU 41 determines that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 2 in step S126, the random counter MR1 and the random counter of the hold data storage unit 101 of the hold number 2 are stored in step S127. Each of MR2 and random counter MR3 is shifted to the hold data storage unit 101 of hold number 1. Then, the process proceeds to step S128, and it is determined whether or not the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 3. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 with the hold number 3, the process proceeds to step S132, and (2) is set in the process flag of the flag storage unit 103. .

  If the CPU 41 determines that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 with the hold number 3 in step S128, the random counter MR1 and the random counter of the hold data storage unit 101 with the hold number 3 are determined in step S129. Each of MR2 and random counter MR3 is shifted to the hold data storage unit 101 of hold number 2. Then, the process proceeds to step S130, and it is determined whether or not the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 4. If it is determined that the random counter MR1 to the random counter MR3 are not recorded in the hold data storage unit 101 with the hold number 4, the process proceeds to step S132, and (2) is set in the process flag of the flag storage unit 103. .

  If the CPU 41 determines in step S130 that the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 with the hold number 4, the random counter MR1 and the random counter of the hold data storage unit 101 with the hold number 4 are stored in step S131. Each of MR2 and random counter MR3 is shifted to the hold data storage unit 101 of hold number 3. Then, the process proceeds to step S132, and (2) is set in the process flag of the flag storage unit 103. That is, when the special symbol game is started, the oldest random counter MR1, random counter MR2, and random counter MR3 are erased from the hold data storage unit 101 with the hold number 1, and the remaining random counter MR1 and random counter MR2 are deleted. And the random counter MR3 are shifted to the previous stage.

  FIG. 36 shows the normal hold mode return process in step S124, and the CPU 41 determines in step S141 whether or not the special hold symbol flag in the flag storage unit 103 is set to the on state. If it is determined that the special reserved symbol flag in the flag storage unit 103 is set to the ON state, the counter MN1 in the counter storage unit 105 is compared with the limit value (0) recorded in advance in the ROM 42 in step S142. If it is determined that “MN1> 0”, the unit value (1) recorded in advance in the ROM 42 is subtracted from the counter MN1 of the counter storage unit 105 in step S143.

  If the CPU 41 determines that “MN1 = 0” in step S142, the second byte data is detected from the selection result of the change start command in step S144, and the detection result of the second byte data is recorded in the ROM 42 in advance. Compare with the complete deviation judgment value (16h). For example, a fluctuation start command 8001h for normal reach (big hit), a change start command 8011h for normal reach (big hit), a change start command 8002h for shoji reach (big hit), a change start command 8012h for shoji reach (out) and card reach ( Big start) change start command 8003h, card reach (start) change start command 8013h, bath reach (big hit) start change command 8004h, bath reach (out) change start command 8014h and proposal reach (big hit) When either the change start command 8005h for change or the change start command 8015h for proposal reach (displacement) is selected, the detection result of the second byte data is different from the complete deviation determination value (16h) in step S144. And Return the game mode by setting the special hold symbol flag in the flag storage unit 103 to the OFF state from the special hold mode to the normal hold mode in step S145, it transmits a hold symbol command C001h to effect control circuit 60 in step S146.

  FIG. 37 explains how the game mode is switched between the normal hold mode and the special hold mode. In the state where the game mode is set to the normal hold mode, the hold data storage unit 101 with the hold number 1 holds the game mode. Data [1] is recorded, and the hold data [2] is recorded in the hold data storage unit 101 of the hold number 2. When the game mode is switched from the normal hold mode to the special hold mode by recording the latest hold data [3] in the hold data storage unit 101 of the hold number 3 in the set state of the normal hold mode, it continues at least. The number of times MN1 is set to (4), which is larger by a fixed value (1) than the current number of pending data.

  In the setting state of the special hold mode, when the first special symbol game is started based on the hold data [1], the minimum continuation number MN1 is subtracted from (4) to (3), and based on the hold data [2]. When the second special symbol game is started, the minimum continuation number MN1 is subtracted from (3) to (2), and the minimum special game is started when the third special symbol game is started based on the hold data [3]. The number of continuations MN1 is subtracted from (2) to (1) and is newly recorded in the hold data storage unit 101 of hold number 1, hold number 2, hold number 3, or hold number 4 next to hold data [3] When the fourth special symbol game is started based on the hold data [4], the minimum continuation count MN1 is subtracted from (1) to (0), and hold number 1 or hold number next to hold data [4] 2 or hold number 3 Minimum number of times of continuation MN1 if pending data storage unit 101 newly recorded pending data fifth special symbol game of based on [5] to the hold number 4 is started is maintained at (0). When the hold data [5] is for normal reach, shoji reach, card reach, bath reach, or proposal reach, the game mode is switched from the special hold mode to the normal hold mode, and the game is for full release. The special hold mode continues.

The special hold mode is a variable one or more special symbol games that are variable after the end of the special symbol game video displayed based on the random counter MR1 in which the jackpot determination is pre-read in the special hold mode changing process of FIG. When the video is finished, the random counter MR2 is returned to the normal hold mode, and the selection of the change start command 80014h for bath reach or the change start command 80015h for proposal reach is pre-read in the special hold mode change process of FIG. When the video of the special symbol game that is variable one or more times after the video of the special symbol game displayed on the basis of is finished, the normal holding mode is returned, and the minimum continuation number MN1 is shown in FIG. Special figure displayed on the basis of the random counter MR1 in which the jackpot determination is pre-read in the special hold mode change processing of It functions as identification information for identifying whether or not the video of the game has ended, and the selection of the change start command 80014h for bath reach or the change start command 80015h for proposal reach in the special hold mode change processing of FIG. Functions as identification information for identifying whether or not the video of the special symbol game displayed based on the pre-read random counter MR2 has ended.
[2-4-3] Fluctuation Process FIG. 38 shows the fluctuation process in step S83. This variation process is executed when the process flag of the flag storage unit 103 is set to (2), and the CPU 41 controls the special symbol display 31 to blink by controlling the LED of the special symbol display 31 in step S151. A special symbol is displayed on the container 31 in a fluctuating state. In step S152, the remaining time of the special symbol game is updated by subtracting the unit value ΔT (= 4) recorded in advance in the ROM 42 from the timer MT1 of the timer storage unit 104. In step S153, the timer of the timer storage unit 104 is updated. The subtraction result of MT1 is compared with a limit value (0) recorded in advance in the ROM. If it is determined that “MT1 = 0”, a change stop command (8100h) is transmitted to the effect control circuit 60 in step S154 to notify the end of the special symbol game, and a flag is stored in step S155. (3) is set in the process flag of the section 103.
[2-4-4] Change Stop Processing FIG. 39 shows the change stop processing in step S84. This variation stop process is executed when the process flag of the flag storage unit 103 is set to (3), and the CPU 41 stops the variation display of the special symbol on the special symbol display 31 in step S161. . The special symbol stop display is performed based on the special symbol setting result recorded in the special symbol storage unit 102. If it is determined that the special symbol is out of place, the special symbol change display is “1”. When it is determined that the symbol is a big hit, the special symbol variation display stops at “3”, and when it is determined that the probability variation big hit is, the special symbol variation display is “7”. Stop.

When the CPU 41 stops changing the special symbol in step S161, the CPU 41 sets the waiting time (2 × 1000 msec) in the timer MT1 of the timer storage unit 104 in step S162, and sets the process flag in the flag storage unit 103 to (4) in step S163. Set. This waiting time is recorded in advance in the ROM 42, and when the special symbol game is put on hold in a state where it is determined to be out, the waiting time elapses after the current special symbol game ends. The next special symbol game is started, and if it is determined that it is either normal big hit or probable big hit, the big hit game starts when the waiting time elapses after this special symbol game ends Is done.
[2-4-5] Standby processing FIG. 40 shows the standby processing in step S85. This standby process is executed when the process flag of the flag storage unit 103 is set to (4), and the CPU 41 subtracts the unit value ΔT from the timer MT1 of the timer storage unit 104 in step S171. Update the remaining waiting time. In step S172, the subtraction result of the timer MT1 in the timer storage unit 104 is compared with the limit value (0). If it is determined that “MT1 = 0”, the process proceeds to step S173.

  When proceeding to step S173, the CPU 41 determines whether or not the big hit flag of the flag storage unit 103 is set to the on state. If it is determined that the big hit flag of the flag storage unit 103 is set to the OFF state, the process proceeds to step S174, and the special symbol recording result is deleted from the special symbol storage unit 102. Then, the process proceeds to step S175, and (0) is set in the process flag of the flag storage unit 103. In a state where this process flag is initially set to (0), the process proceeds to the big hit determination process of step S81 in the next process process, and the random counter MR1 to the random counter MR3 are recorded in the hold data storage unit 101 of the hold number 1. If it is a big hit, it is determined by the probability according to the set state of the probability variation mode.

  If the CPU 41 determines in step S173 that the big hit flag of the flag storage unit 103 is set to the on state, the CPU 41 sets the big hit flag of the flag storage unit 103 to the off state in step S176, and the counter of the counter storage unit 105 in step S177. The number of continuations (4) is set in MN2, the limit number (10) is set in the counter MN3 of the counter storage unit 105 in step S178, and the limit time (30 × 1000 msec) is set in the timer MT1 of the timer storage unit 104 in step S179. set. Each of the continuation number, limit number and time limit is recorded in advance in the ROM 42, and the continuation number corresponds to the number of times that a big hit round can be performed in the jackpot game, and the limit number is a special winning opening in the big hit round. 25 corresponds to the maximum number of game balls allowed to win, and the time limit corresponds to the maximum time allowed to open the special winning opening 25 in the big hit round.

When CPU 41 initially sets timer MT1 of timer storage unit 104 in step S179, CPU 41 transmits a big hit game start command B000h to effect control circuit 60 in step S180. Then, in step S181, (5) is set in the process flag of the flag storage unit 103, and in step S182, the special prize opening solenoid 28 is turned on to open the special prize opening 25.
[2-4-6] Jackpot Game Processing FIG. 41 shows the jackpot game processing in step S86. This jackpot game process is executed when the process flag of the flag storage unit 103 is set to (5), and the CPU 41 subtracts the unit value ΔT from the timer MT1 of the timer storage unit 104 in step S191. In step S192, the remaining opening time of the special winning opening 25 is updated, and the subtraction result of the timer MT1 in the timer storage unit 104 is compared with the limit value (0). If it is determined that “MT1 = 0”, the process proceeds to step S196, and the special prize opening 25 is closed by turning off the special prize opening solenoid 28.

  If the CPU 41 determines that “MT1> 0” in step S192, it determines whether a count signal is output from the count sensor 29 in step S193. If it is determined that the count signal is output from the count sensor 29, the process proceeds to step S194, where the unit value (1) recorded in advance in the ROM 42 is subtracted from the counter MN3 of the counter storage unit 105, thereby remaining. The limit number is updated, and the process proceeds to step S195.

  In step S195, the CPU 41 compares the subtraction result of the counter MN3 in the counter storage unit 105 with the limit value (0). If it is determined that “MN3 = 0”, the process proceeds to step S196, and the special winning opening 25 is closed. In other words, the special prize opening 25 is closed when a limited number (10) of game balls are awarded in the special prize opening 25 or the opening time of the special prize opening 25 reaches the limit time (30 × 1000 msec).

  When the special winning opening 25 is closed in step S196, the CPU 41 updates the remaining number of times the special winning opening 25 is opened by subtracting the unit value (1) from the counter MN2 of the counter storage unit 105 in step S197, and the counter is counted in step S198. The subtraction result of the counter MN2 in the storage unit 105 is compared with the limit value (0). If it is determined that “MN2> 0”, the limit number (10) is set in the counter MN3 of the counter storage unit 105 in step S199, and the limit time (30) is set in the timer MT1 of the timer storage unit 104 in step S200. X1000 msec) is set, and the special prize opening 25 is opened again in step S201.

  When the CPU 41 closes the special winning opening 25 for the fourth time in step S196, the CPU 41 subtracts the counter MN2 of the counter storage unit 105 from the limit value in step S197. In step S198, it is determined that “MN2 = 0”, and in step S202, it is determined whether or not the probability variation big hit symbol (7) is recorded in the special symbol storage unit 102. If it is determined that the probability variation big hit symbol (7) is recorded in the special symbol storage unit 102, the probability variation mode is turned on by setting the probability variation flag of the flag storage unit 103 to the on state in step S203, If it is determined that the normal jackpot symbol (3) is recorded in the special symbol storage unit 102, the probability variation mode is turned off by setting the probability variation flag of the flag storage unit 103 to the OFF state in step S204.

When the CPU 41 sets the probability change flag of the flag storage unit 103 to the on state or the off state, the big hit game is notified by sending a big hit game stop command B100h to the effect control circuit 60 in step S205. In step S206, the special symbol recording result is cleared from the special symbol storage unit 102. In step S207, (0) is set in the process flag. That is, the probability variation mode setting process is performed at the end of the fourth jackpot round, and when the probability variation jackpot symbol (7) is stopped and displayed in the last special symbol game, the probability variation mode is turned on, When the normal jackpot symbol (3) is stopped and displayed in the immediately preceding special symbol game, the probability variation mode is turned off.
