Abstract

A specific combination (for example, a rare small combination or a re-playing combination) used as a trigger for an AT lottery is set by a game machine creator in advance. The game becomes uniform because the opportunity of the AT lottery does not change. SOLUTION: There are a plurality of chance zones where the probability of winning an AT is higher than usual, and the player can select which chance zone to use, and it becomes an AT lottery opportunity for the chance zone that can be selected. Roles correspond to all the winning combinations in the internal lottery, and all of the winning combinations can be selected in any chance zone. [Selection] Figure 20

Description

  The present invention relates to a gaming machine such as a slot machine.

  After a medal is inserted or a bet is operated by operating a bet button, a plurality of reels on which a plurality of types of symbols are arranged are rotated by operating a start lever, and a plurality of reels controlled to stop based on operation of a stop button are operated. There is a gaming machine that grants a privilege corresponding to a combination when the combination of the stop symbols matches a combination of symbols corresponding to the combination on a predetermined activated pay line.

  In addition, when the pressing order of the left stop button, the middle stop button, and the right stop button is a predetermined correct answer, it is a period in which a role including a small role to be won is selected as a lottery object and the correct answer pressing order is notified. There is a gaming machine having a normal period which is a period in which AT is not notified. The AT is started by executing a predetermined number of games or by an AT lottery based on the winning combination, and when the AT is executed for a predetermined number of times, the AT ends and returns to a normal period.

  There is a chance zone in which an AT lottery performed based on a specific combination is highly probable within a predetermined period of a normal period. However, the chance zone does not increase the probability of a specific combination, but only increases the probability of AT lottery performed based on the specific combination. For this reason, no matter how high the AT lottery probability is, the AT lottery is not carried out unless the important role is won, so the benefit that the AT lottery probability is increased cannot be obtained.

JP2013-78676A

  Because the specific role that triggers the AT lottery (for example, a rare small role or a replaying player whose winning probability is relatively low) is used by a game machine creator, the probability of AT lottery is increased. However, there is a problem that the game becomes uniform because the opportunity of AT lottery does not change. Even if a plurality of chance zones can be selected as in Patent Document 1, if a specific combination that is a lottery opportunity for AT lottery is determined in advance, the fact that winning of the specific combination is an indispensable condition remains the same. There is no sense of convincing for the choice. For example, even if a chance zone can be selected from a plurality of chance zones as in Patent Document 1, any chance zone can be selected as long as the AT lottery opportunity does not change between the normal period and the chance zone period. There is no convincing choice. This impairs interest.

A gaming machine that gives a player a privilege according to a combination of symbols displayed on an active line when a plurality of reels with a plurality of different types of symbols rotate and all reels stop. An internal lottery means for determining one of a plurality of types including a winning combination, and an AT lottery for determining whether to start an AT based on the winning combination determined by the internal lottery means On the condition that the execution right grant lottery that determines whether or not to grant the execution right based on the AT lottery means and the winning combination determined by the internal lottery means, and that the execution right is granted, a state switching means for switching to one of a plurality of special state in which the aT lottery higher winning probability than the normal state from a normal state to perform the aT lottery with a predetermined probability by the aT lottery means The plurality of special states include a first special state in which the AT lottery is performed by the first AT lottery means based on the winning of the specific combination, and a winning of any combination other than the specific combination and a second special state in which the aT lottery second aT lottery means based on said state switching means, the not in the normal state only, is switched to one of the plurality of special state The execution right grant lottery is performed during the period, and the execution right grant lottery is won during the normal state and the execution right is granted, or the state is switched to one of the plurality of special states. In order to determine one of the plurality of special states on condition that the execution right granting lottery is won during a certain period and the execution right is granted and one of the plurality of special states is completed Selection by the player Accepting said it from the normal state the game machine and switches to a special state selected from among the plurality of special state in response to the selecting operation.

  According to this configuration, it is possible to arbitrarily select a special state having a different role that triggers the AT lottery, and the game is not uniform.

  Further, the first special state further includes an accumulating means for accumulating points based on the winning of the specific role by the internal lottery means, and the first AT lottery means performs AT with a probability corresponding to the points accumulated by the accumulating means. 2. The gaming machine according to claim 1, wherein a lottery is performed.

  According to this configuration, the selected first special state is not an AT lottery in one game, but an AT lottery is performed based on the results in a plurality of games, so the game is not uniform and interesting. Get higher.

  The game according to claim 1 or 2, wherein the second AT lottery means performs an AT lottery with a probability corresponding to the number of consecutive winnings of a role other than the specific role in the second special state. Machine.

  According to this configuration, the selected first special state does not perform AT lottery in one game, but does not make the game uniform because AT lottery is performed based on continuity of results in a plurality of games. Increases interest.

  In addition, the gaming machine is characterized in that the specific period is extended when a part of the combination including other than the specific combination is won in the last game of the second specific period.

  According to this configuration, when a specific role is played in the game before the last game, the last game becomes a simple digest game, thereby preventing the interest from deteriorating.

  In addition, in the game in which the first AT lottery is performed during the first specific period, the specific combination includes a rare specific combination with a low internal winning probability, and if the rare specific combination is won in the internal lottery of the game, The gaming machine is characterized in that a first AT lottery is performed based on a sum of points corresponding to a second specific combination.

  According to this configuration, it is more interesting to have a rare specific combination that becomes an opportunity in both the first specific period and the second specific period.

  There are multiple specific periods with different lottery opportunities, and it has a configuration that allows the player to select the specific periods, providing a game with a sense of convincing the player, and improving the fun of the game Provide gaming machines.

<4-3: Explanation of various games in the slot machine>
FIG. 6 is an explanatory diagram showing the state transition of the game performed in the slot machine 1.
(1) Start and End of Type 2 BB Game When the Type 2 BB start combination is won by internal lottery during the normal game and the Type 2 BB start combination is established and won, the Type 2 BB game is started from the next game. The two-type BB game ends when the acquired number of games in the two-type BB game exceeds the prescribed number.
(2) Two-type BB inside game When the two-type BB start combination is won in the internal lottery during the regular game, if the two-type BB start combination is not established, the winning flag of the two-type BB will be displayed until the next game is won. It becomes a two-type BB inside game that is carried over. When the two-type BB start combination is established in the two-type BB inside game and the prize is won, the second-type BB game is started from the next game.
(3) Game flow A normal game is started by changing the setting or resetting the RAM. If the 2nd class BB role is won internally during a regular game, the game where the 2nd class BB role is won uses a stop table that can win the 2nd class BB start role. I can. In the two-type BB internal game, the winning flag of the second-type BB start combination is carried over, but there is no unselected lottery division, and any combination is won. Since the stop table is created so that the replay and the small combination can be preferentially drawn over the two-type BB start combination, the game machine of the present application does not transit from the second-type BB internal game to another game state. Therefore, several games immediately after the setting change or the RAM reset stay in the normal game, but after winning the two-type BB start combination, they stay in the two-type BB all the time until the setting change or the RAM reset is performed again. Therefore, the height of the balls is given by the state transition of the sub-board 100B described later.

FIG. 7 is a flowchart showing the contents of the flow of one game. First, based on the medal insertion signal 160 or the bet operation instruction signals 111a to 111c, the CPU 101 determines whether or not an insertion bet operation by inserting a medal or a storage bet operation by pressing the bet button 11 has been performed. Wait until it is detected (S100). When the signal is detected, the process proceeds to the next, and it is determined whether or not the start lever operation has been performed based on the start operation instruction signal 112, and waits until the signal is detected (S101). When the signal is detected, the betting operation is prohibited (S102). More specifically, the solenoid of the medal selector device is turned off by the medal block signal 161, the passage route of the medal selector device is switched, and the game medal is discharged to the medal tray 40 even when it is inserted from the medal insertion slot 10. Also, bet operation instruction signals 111a to 111c are not accepted.

Next, the CPU 101 sequentially increments every 10 nanoseconds in the range of 0000H to FFFFH, acquires a counter value from the counter circuit that makes one cycle in about 1.6 milliseconds via the input port 107, and sets it as a random value (S103). ). Next, by referring to the game type data, a combination lottery table corresponding to the type of the game is selected (S104). Using the selected combination lottery table, it is determined which numerical value range the acquired random number value is set for each combination group on the combination lottery table, and the winning flag of the combination is set (S105). ). Next, based on the winning flag set in step S105, a stop data table group to be referred to in stop control is selected (S106). The stop data table group is designed so that the reels stop within a maximum of 4 frames in number of symbols from when one of the stop buttons 13a to 13c is pressed. This is synonymous with stopping the reel within 190 ms from when any of the stop buttons 13a to 13c is pressed. The steady speed of the reel is 80 rpm, and 21 symbols are arranged per reel. Therefore, it progresses a little with 5 symbols from the position where the stop button was pressed in 190 ms. When the stop at the position where the stop button is pressed is drawn zero frames or the bitter is pressed, the symbols on the reel advance to a maximum of four frames.

  In this example, since the minimum consumption time of one game is 4.1 seconds, the timer value that counts down to 0 every 2 milliseconds indicating the elapsed time of one game is referred to, and waits until the timer value reaches 0 (S107). When the timer value reaches 0 to start rotation of the reel as a starting point for measuring the elapsed time of one game, the timer value is set to an initial value (2050) corresponding to 4.1 seconds, and three reels To drive the reel drive signals 154a to 154c to rotate the stepping motor simultaneously or sequentially (S108). Specifically, the reel drive signals 154a to 154c include a plurality of drive signal lines for exciting a plurality of winding phases, and the reels are supplied by supplying a pulse signal to each drive signal line in a predetermined phase pattern. Rotate. Also, even if the start lever is operated in step S101, if 4.1 seconds have not elapsed since the start of rotation of the reel of the previous game, the reels R1 to R3 immediately enter a standby state without rotating and enter a standby state. Inform the player of this by a lamp or sound.

  Next, after letting all three reels R1 to R3 reach a constant rotational speed through an acceleration period of 10 steps, the CPU 101 uses an LED built in the stop button to inform that the stop buttons 13a to 13c can be received. Light up. When the stop operation instruction signals 113a to 113c are detected and the stop button is operated, the operation is stopped from the stop button operation position and the stop data in the stop data table group based on the stop data table group selected in step S106. Reel stop processing that determines the symbol, applies brake force by all-phase excitation that simultaneously excites all winding phases, and rotates and stops by inertia corresponding to 15 steps after starting all-phase excitation. This is performed for the reel (S109). After the start of rotation of the reels R1 to R3, the reels are automatically stopped for reels that have not been stopped even after 30 seconds.

  Next, when all reels are stopped, the CPU 101 determines whether or not a winning combination is established on a valid winning line (S110), and if winning, a game value set for each winning combination is given. To do. Next, with reference to the game type data, it is determined whether or not a two-type BB game is being played (S111). If it is determined that a game is being played, a special game end determination process is performed (S112), and then winning A flag clear process is performed (S113). Here, if the winning flag established in the game is a starter that can carry over the flag, the winning flag is cleared only when winning, and the winning flag is not cleared if it is missed without winning. . On the other hand, if the winning flag established in the game is a small role, the winning flag is cleared regardless of winning or missing. Subsequently, the prohibition of the bet operation performed in step S102 is canceled (S114), the game medal can be inserted or the input of the bet button 11 can be accepted, and the process returns to step S100 to prepare for the start of the next game.

<5-2: Role lottery table determination process>
FIG. 8 is an explanatory diagram showing the content of the lottery according to the game type selected in the role lottery table determination process in step S104. During the regular game, the lottery probability for determining either the re-playing role, the 8 small roles, the 1 small roles A to W, the 5 small roles A to E, or the loser by lottery is 65536 minutes each. Set the value and set the winning flag for the winning combination. During various internal games, lottery probabilities for determining any one of the re-playing role, small role or lose are set by lottery, and the winning flag of the winning combination is set. The lottery probabilities of the small roles during the normal game and various internal games are the same. The data in which data indicating these lottery probabilities are set are referred to as a role lottery table TBL8001 and TBL8002, respectively.

  During the two-type BB game, a lottery group 1 which is a lottery division for deciding either a re-playing role, 8 small roles, 5 small roles A to E, 1 small roles A to W or lose Lottery group 2, lottery group 3, lottery group 4, lottery group 5, lottery group 6, lottery group 7, lottery group 8, lottery group 9, lottery group 10, lottery group 11, lottery group 12, lottery group 13, lottery The probabilities are set to 6400, 6400, 6400, 6400, 6400, 6400, 1000, 200, 800, 400, 300, 21435 and 3000, respectively, and the winning flag of the winning combination is set. If multiple winning combinations are won simultaneously, all winning flags are set. A set of data indicating these lottery probabilities is referred to as a role lottery table TBL8003.

  The CPU 101 manages the game types as game type data, such as 00H for a normal game, 01H for a BB internal game, and 10H for a BB game.

<5-3: Winning flag set processing>
FIG. 9 is a flowchart showing the contents of the winning flag setting process in step S105. In this winning flag setting process, the winning random number value and the winning lottery table TBL8001 to TBL8003 corresponding to the type of game determined in step S104 are set to the winning flag effective for the game. However, the winning flags that are set differ depending on the game if the winning lottery table is different, and the winning flags that are set differ depending on the random number value even in the same winning lottery table. If there is a winning flag carried over from the previous game, a plurality of winning flags are set by combining the carry-over flag and the random number value acquired in the game. In the two-type BB game, the winning combination is also set in the small role without being based on the acquired random number value.

<5-4: Stop data selection process>
FIG. 10 is a flowchart showing the contents of the stop data selection process in step S106. In this stop data selection process, a stop data table group used in stop control is selected from the winning flag set in step S105. As shown in FIG. 11, the stop data table groups TBL21 to TBL32 set for each combination further include three stop data table groups TBL21A to TBL21C (lottery group 1) for the left reel R1, middle reel R2, and right reel R3. In addition, for each reel, stop data tables TBL21A1 to TBL21A5 (example of lottery group 1) at the time of the second stop and the third stop are provided. In addition, since the stop data table is switched according to the stop operation of the player, it is not necessary to specify and select the stop data table to be finally used that is selected during the stop operation.

  First, the CPU 101 refers to the winning flag to determine whether or not the lottery group 1 condition device is set (S106a), and if it is determined that it is set, selects the replay stop data table group TBL21. (S106b).

  Next, the CPU 101 refers to the winning flag to determine whether or not the lottery group 4 condition device is set (S106g). If it is determined that it is set, the lottery group 4 stop data table group TBL24. Is selected (S106h).

  Next, the CPU 101 refers to the winning flag to determine whether or not the lottery group 5 condition device is set (S106i). If it is determined that the lottery group 5 condition device is set, the lottery group 5 stop data table group TBL25 is determined. Is selected (S106j).

  Next, the CPU 101 refers to the winning flag to determine whether or not the lottery group 6 condition device is set (S106k). If it is determined that the lottery group 6 condition device is set, the lottery group 6 stop data table group TBL26. Is selected (S106l).

  Next, the CPU 101 refers to the winning flag to determine whether or not the lottery group 7 condition device is set (S106m). If it is determined that the lottery group 7 condition device is set, the lottery group 7 stop data table group TBL27 is determined. Is selected (S106n).

  Next, the CPU 101 refers to the winning flag to determine whether or not the lottery group 8 condition device is set (S106o). If it is determined that the lottery group 8 condition device is set, the lottery group 8 stop data table group TBL28 is determined. Is selected (S106p).

  FIG. 12A is an explanatory diagram showing a stop data table to be stopped at the pay line L1 used for each reel selected in the stop data selection process. 12A (A) shows the symbol arrangement of the left reel band, and FIGS. 12A (B), (C), (D), (E), (F), and (G) are bell symbol stop data tables TBL1201, A plum symbol stop data table TBL1202, a red 7 symbol stop data table TBL1203, a red 7 blue 7 symbol stop data table TBL1204, a cherry symbol stop data table TBL1205, and a watermelon symbol stop data table TBL1206 are shown. These stop data tables indicate the number of frames ahead from the symbol position (stop symbol position) detected immediately after the stop position detected by the stop instruction signal 113c. The number of frames is stored. “0” means stop at the stop symbol position, and “4” means stop at the symbol position four frames ahead. Note that the stop data table only needs to be able to indicate to which symbol it is advanced and stopped. Therefore, the stop data table for bell symbol in FIG. 14B is not the number of advance frames such as “0” to “4”. The symbol number PN to be stopped as described in parentheses may be stored.

  The bell symbol stop data table TBL1201 can stop the bell symbol at the middle stage (winning line L1 position) regardless of the symbol number PN = 1 to 21 in the stop symbol position. Also, the plum symbol stop data table TBL1202 can stop the plum symbol at the middle stage (winning line L1 position) regardless of the symbol number PN = 1 to 21 in the stop symbol position. Thus, if five of the 21 symbols are arranged within an interval of 4 frames, the symbols can be stopped without fail at any position. Such bell designs and plum designs are called 100% retracted designs.

  The red 7 symbol stop data table TBL1203 can stop the red 7 symbol at the middle stage (winning line L1 position) only when the stop symbol position is 5 locations of symbol numbers PN = 15-19. If the stop symbol position is other than that, the plum symbol is stopped in the middle.

  The red 7 symbol blue 7 symbol stop data table TBL1204 can stop the red 7 symbol at the middle stage (winning line L1 position) only at the four stop symbol positions of symbol numbers PN = 16-19. The blue 7 symbol can be stopped at the middle stage (winning line L1 position) only at the four symbol numbers PN = 11-15. If the stop symbol position is other than that, the plum symbol is stopped in the middle.

  The cherry symbol stop data table TBL1205 can stop the cherry symbol at the middle stage (winning line L1 position) only at the four stop symbol positions of symbol numbers PN = 5-9. If the stop symbol position is other than that, the plum symbol is stopped in the middle.

  The watermelon symbol stop data table TBL1206 can stop the watermelon symbol at the middle stage (winning line L1 position) at the 20 stop symbol positions of symbol numbers PN = 1 to 6, 8-21. If the stop symbol position is other than that, the plum symbol is stopped in the middle.

  When the stop operation timing of the player is the symbol number PN = 5, for example, when the bell symbol stop data table TBL1201 is selected, the advance frame number “3” is acquired and the symbol number PN = 8. Is displayed in the middle row, and when the plum symbol stop data table TBL1202 is selected, the advance frame number “2” is acquired, the plum symbol of symbol number PN = 7 is displayed in the middle row, red 7 When the symbol stop data table TBL1203 is selected, the advance frame number “2” is acquired, the plum symbol of symbol number PN = 7 is displayed in the middle, and the red 7 blue 7 symbol stop data table TBL1204 is selected. If it is, the advance frame number “2” is acquired, the plum symbol of symbol number PN = 7 is displayed in the middle, and the cherry pattern stop data table TBL12 is displayed. If 5 is selected, the advance frame number “4” is acquired, the cherry symbol of symbol number PN = 9 is displayed in the middle stage, and if the watermelon symbol stop data table TBL 1206 is selected, the advance frame is displayed. The number “1” is acquired, and the watermelon symbol of symbol number PN = 6 is displayed in the middle. Depending on the stop data table selected in this way, the symbols to be stopped in the middle stage are different even at the same stop operation timing.

<5-5: Reel stop processing>
13 and 14 are flowcharts showing the contents of the reel stop process in step S109. In this reel stop process, predetermined symbols are stopped in the order of stop buttons operated to stop according to the stop data in the stop data table group determined based on the winning flag in step S106. During the normal game and the two-type BB internal game, a process of stopping the symbols based on the winning flag that is a maximum of four frames ahead from the stop position is performed. During the two-type BB game, the right reel and the middle reel perform the process of stopping the symbols based on the winning flag up to four frames ahead from the stop position, as in the other games, but the left reel has a maximum of 1 from the stop position. A process for stopping the symbol based on the winning flag up to the top of the frame is performed.

  First, the CPU 101 determines whether or not 30 seconds have elapsed from the start of rotation (S109a), and determines whether or not a first stop button stop operation has been performed based on the stop instruction signals 113a to 113c (S109b). If any one of the stop instruction signals 113a to 113c is detected, it is determined that the first stop button stop operation has been performed. If it is determined in step S109a that 30 seconds have elapsed, an automatic stop instruction is issued to the left reel at that time (S109c).

  Next, the CPU 101 acquires a stop button number indicating the type of stop button from the detected stop instruction signals 113a to 113c, and acquires a symbol number PN immediately after the stop operation (S109d). Specifically, the stop button number and the symbol number PN at the timing are acquired by detecting stop instruction signals 113a to 11c that are output when the stop buttons 13a to 13c are pressed. In this example, stop button numbers “1”, “2”, and “3” are assigned to the stop buttons 13a, 13b, and 13c, respectively.

  Next, the CPU 101 limits the stop data table groups that can be used from the stop button number among the stop data table groups based on the winning flag selected in the reel stop data table group selection process in step S106 (S109e). Specifically, it is determined whether the symbol to be stopped can be stopped at any one of an upper stage, a middle stage, and a lower stage. In the case of the left reel, a winning line L2 or L4 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L5 if it can be stopped in the lower stage. In the case of the middle reel, the winning line L2 is a candidate for the winning line if it can be stopped in the upper stage, the winning line L1, L4 or L5 if it can be stopped in the middle stage, and the winning line L3 if it can be stopped in the lower stage. In the case of the right reel, a winning line L2 or L5 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L4 if it can be stopped in the lower stage. If it is possible to stop at a plurality of stages, one stop data table for a predetermined line is selected by lottery or the like from among the winning line candidates combined with them.

  Next, the CPU 101 determines whether or not the stop-operated reel is the left reel and is in the two-type BB game (S109f), and the stop-operated reel is the left reel (stop button number = 3). If it is determined that the two-type BB game is in progress, the low pull-in stop data table for the left reel is determined from the stop data table group for the predetermined line (S109h), and it is determined that this is not the case. In this case, a stop data table based on the stop button number is determined (S109g).

  Next, the CPU 101 acquires the advance frame number corresponding to the symbol number PN acquired in step S109d from the determined stop data table, and stops the reel that has been stopped based on the advance frame number (S109i).

  Next, the CPU 101 determines whether or not 30 seconds have elapsed from the start of rotation (S109j), and determines whether or not there is a second stop button stop operation based on the stop instruction signals 113a to 113c (S109k). . If any one of the stop instruction signals 113a to 113c other than those already detected is detected, it is determined that the second stop button stop operation has been performed. If it is determined in step S109j that 30 seconds have elapsed, an automatic stop instruction is issued to one of the remaining reels operating at that time (S109l).

  Next, the CPU 101 acquires a stop button number indicating the type of the stop button from the detected stop instruction signals 113a to 113c, and acquires a symbol number PN immediately after the stop operation (S109m).

  Next, the CPU 101 determines whether or not the stopped reel is the left reel (stop button number = 3) and the two-type BB game is being played (S109n), and the stopped reel is the left reel. If it is determined that the two-type BB game is in progress, a low pull-in stop data table for the left reel is determined from the stop data table group for the predetermined line (S109p). In this case, a stop data table based on the stop button number is determined (S109o).

Next, the CPU 101 acquires the advance frame number corresponding to the symbol number PN acquired in step S109k from the determined stop data tail, and stops the reel that has been stopped based on the advance frame number (S109q).

  Next, the CPU 101 determines whether or not 30 seconds have elapsed from the start of rotation (S109r), and determines whether or not there is a second stop button stop operation based on the stop instruction signals 113a to 113c (S109s). . When any one of the stop instruction signals 113a to 113c other than those already detected is detected, it is determined that the stop operation of the third stop button has been performed. If it is determined in step S109n that 30 seconds have elapsed, an automatic stop instruction is issued to the remaining reels (S109t).

  Next, the CPU 101 acquires a stop button number indicating the type of the stop button from the detected stop instruction signals 113a to 113c, and acquires a symbol number PN immediately after the stop operation (S109u).

  Next, the CPU 101 determines whether or not the stopped reel is the left reel (stop button number = 3) and the two-type BB game is being played (S109v), and the stopped reel is the left reel. If it is determined that the two-type BB game is in progress, a low pull-in stop data table for the left reel is determined from the stop data table group for the predetermined line (S109x), and it is determined that this is not the case. In this case, a stop data table based on the stop button number is determined (S109w).

Next, the CPU 101 acquires the advance frame number corresponding to the symbol number PN acquired in step S109u from the determined stop data tail, and stops the reel that has been stopped based on the advance frame number (S109y).

<5-6: Winning determination process>
FIG. 15 is a flowchart showing the contents of the winning determination process in step S110. In this winning determination process, the combination of symbols arranged on the winning line after the reels are stopped is checked to determine whether or not a winning is achieved. If it is determined that a winning combination is made, a process for starting the two-type BB game is performed if it is a two-type BB start combination, and a payout is given if it is a small combination.

  First, the CPU 101 determines whether or not a re-game player has been won (S110a). If it is determined that a win has been won, the re-game win flag of bit 0 of the winning information 1 data is cleared (S110b). Subsequently, an automatic bet process is performed (S100a in FIG. 8), and the process returns to step S101.

  Next, the CPU 101 determines whether or not the eight small winning combination has been won (S110c), and if it is determined that the winning has been won, a payout process for eight medals is performed (S110d). In this payout award process, payout credit processing for adding the number of payouts to the credit up to the credit upper limit value (50) is performed, and for the portion exceeding the credit upper limit value, the payout of paying out medals from the medal payout device to the medal tray 40 Switch to processing. Subsequently, it is determined whether or not a single small combination A to W has been won (S110e), and if it is determined that a prize has been won, a payout process for one medal is performed (S110f). Subsequently, it is determined whether or not the five small bonuses A to E have been won (S110g). If it is determined that the winning has been won, a payout process for five medals is performed (S110h).

  Next, the CPU 101 determines whether or not the two-type BB combination has been won (S110k). If it is determined that the winning has been won, the CB game flag in bit 6 of the game type data is set to "1" ( S110l). Subsequently, the acquired number counter is cleared (S110m).

<5-7: Special game end determination process>
FIG. 16 is a flowchart showing the contents of the special game end determination in step S112. In this special game end determination process, it is determined whether or not the end condition is satisfied when a special game (two-type BB game) having a predetermined game end condition is being performed.

  First, when it is determined that the two-type BB game is in progress, the CPU 101 determines whether or not a small bonus is won and a dividend is awarded in this game (S112b). If a payout is generated, the payout is added to the acquired number counter value (S112c), and the acquired number is displayed on the acquired number display 23b (S112d).

  Next, the CPU 101 compares the acquired number counter value with the acquired number upper limit determination value determined in the two-type BB game (S112e). The acquired number upper limit determination value is a value that is 15 smaller than the acquired number upper limit value that must not be exceeded during the game determined in the two-type BB game. If the acquired number upper limit determination value is exceeded in step S112e, the two-type BB in-game flag is cleared (S112f).

<5-8: Winning flag clear process>
FIG. 17 is a flowchart showing the contents of the winning flag clear process in step S113. In this winning flag clear process, the winning flag set by internal lottery or the like during one game is cleared at the end of one game or carried over to the next game without being cleared.

  First, the CPU 101 clears the winning information 2 data (S113a). The 8 winning combination winning flag, the 1 winning combination A to W winning flag and the 5 winning A to E winning flag are cleared unconditionally because they are cleared in one game regardless of winning.

Next, the CPU 101 determines whether or not the FB winning flag is set with reference to bit 4 of the winning information 1 data (S113b), and if it is determined that the flag is set, the FB winning flag is set. Clear (S113c).

  Next, the CPU 101 determines whether or not the type 2 BB winning flag is set (S113d). If it is determined that the flag is set, the CPU 101 further determines whether or not the type 2 BB winning combination has been won. If it is determined (S113e) and it is determined that the two-type BB start combination has been established and won, the second-type BB winning flag is cleared (S113f). If it is determined in step S113e that the game has not been won, the two-type BB internal game in-progress flag is set to “1” (S113g), and the second-type BB internal game is set from the next game.

<6-1: Sub-substrate processing flow>

The CPU 181 reads the program stored in the ROM 194 based on the timing of the CLK signal generated by the clock generation circuit c192, and sequentially executes the program. When the power is turned on, the CPU 181 executes a program from a predetermined address, and at the timing of the INTR signal generated by the clock generation circuit c193 different from the cycle of the clock generation circuit c192 in the initialization process (S1101). The interrupt program starting from a predetermined address is set to be executed.

  The data transmitted from the data transmission circuit 106 of the main board 100A is transmitted to the data input circuit 196. When receiving the data, the data input circuit 196 transmits an interrupt signal INTR2 to the CPU 191. When the CPU 191 receives the interrupt signal INTR2, the CPU 191 temporarily stops the program that is currently being executed, and a program corresponding to the interrupt signal INTR2 (hereinafter referred to as a communication interrupt program) is executed. The communication interrupt program reads the data received by the data input circuit 196 and stores it in the communication queue on the RAM 195, and the communication interrupt program ends. When the communication interrupt program ends, the program that has been suspended is resumed.

  FIG. 18 is a flowchart showing the flow of the main program of the sub board 100B. The CPU 191 decodes the first data from the communication queue turned by the communication interrupt program in the communication command processing of S1802, and writes necessary data on the RAM 195. For example, if the winning combination information is transmitted together with the lever ON, the winning combination information is updated in the area for storing the winning combination information on the RAM 195.

  In step S1803, a sub game progress process is executed. In the sub-game progress process, the picture updated in S1802 is determined in consideration of the current execution effect and what picture is displayed and is written in the drawing queue.

  In step S1804, the CPU 191 designates image information to be drawn on the display circuit 197 based on the data written in the drawing queue. The display circuit 197 outputs a VSYNC signal to the CPU 191 when drawing for one screen is completed. In step S1805, the CPU 191 waits until the VSYNC signal is input from the display circuit 197. When the VSYNC signal is input, the CPU 191 proceeds to S1802 and communication command processing is performed again. Generally, the VSYNC signal is generated at 1/60 second intervals.

  FIG. 19 is a flowchart showing the contents of the sub game execution process S1803. Since the sub game execution process S1803 is a process called from the main process of the sub board, it is processed at an interval of 1/60 seconds. In the sub game execution processing S1803, processing is performed according to the states of initialization state, setting change state, normal power interruption state, long-term power interruption state, normal game state, AT gaming state, chance zone 1 state, chance zone 2 state. . The initialization state, the setting change state, the normal power-off state, and the long-term power-off state are states in which the game machine 1 stays until the game starts after the power is turned on. It is always initialized after power is turned on. In the initialization state, when the sub-board is initialized, the sub-board controls the mechanical accessory, etc., the operation of the mechanical accessory is confirmed and the work is returned to the initial position of the mechanical accessory (S1902). When the initialization of the sub-board is completed, it shifts to another state. If the setting change key is ON after the initialization of the sub-board, etc., the setting change state is entered. If the setting change key is OFF after the initialization process S1902 has been completed, and it has been less than 3 hours since the power was turned off, the normal power-off state is entered. Transition to long-term power interruption.

  The CPU 191 determines whether or not the current state is the setting change state (S1903). If the current state is the setting change state, the sub game setting change processing S1904 is executed. In the sub game setting change processing S1904, the display indicating that the setting is being changed is displayed on the liquid crystal display device 30, and the sound whose setting is being changed is played on the speaker 32.

  The CPU 191 determines whether the current state is a normal power interruption state (S1905). If the current state is a normal power interruption state, a normal power interruption process S1906 is executed. In the normal power-off process S1906, the information when the power is turned off is backed up in the nonvolatile RAM, and the AT game state is entered when the power is turned off. Otherwise, the AT game state is entered. Transition to the normal gaming state.

  The CPU 191 determines whether the current state is a setting change state (S1907). If the current state is a long-term power interruption state, a long-term power interruption process S1908 is executed.

  In the long-term power interruption processing S1908, the effect displayed on the liquid crystal display device 30 is returned to the default, and when the power is turned off, the gaming state is shifted to the AT gaming state. Otherwise, the transition is made to the normal gaming state. .

  The CPU 191 determines whether or not the current state is a setting change state (S1909). If the current state is the normal game state, the normal game process S1910 is executed.

  The normal game process S1910 executes an effect that is performed every game in the normal game state. Specifically, the operation information such as lever ON is switched based on the operation information received by the communication command. When a game is executed for a predetermined number of games, the player is allowed to select either the chance zone 1 or the chance zone 2 and shift to the state of the chance zone selected by the player. If the player does not decide which chance zone to select during a certain period of time, either one of the chance zones determined in advance or the chance zone will be determined by lottery, and will be in the state of the determined chance zone Transition. Further, when a chance zone lottery is performed on the basis of the received combination information, the player is allowed to select either the chance zone 1 or the chance zone 2 and shift to the state of the chance zone selected by the player. If the player has not decided which chance zone to select during a certain period, the chance zone is decided in the same manner as described above. The operation mode will be described in detail with reference to FIG.

  In addition, in relation to the chance zone 2, the chance zone lottery is also performed during the chance zone 2, and if it is won, the execution right is stocked and the chance zone selection screen is displayed again after the chance zone 2 is finished. become.

  In the normal game process S1910, even if the chance zone lottery or the like does not cause a transition to the chance zone state, if the chance zone winning is stocked, the normal game processing immediately shifts to the chance zone state or plays a game in the normal game state for several games. Then, move to the chance zone state. By this process, when the chance zone lottery is performed in a state other than the normal gaming state, the chance zone lottery can be started when the game state is shifted to the normal gaming state. For example, when a chance zone lottery is won in the chance zone state, a new chance zone cannot be executed immediately. In such a case, the winning of the chance zone is stocked, and the chance zone state ends, and after returning to the normal gaming state, it is possible to shift to the chance zone state again. This process is performed to eliminate the loss of the so-called chance zone lottery.

  The CPU 191 determines whether the current state is the AT gaming state (S1911). If the current state is the AT gaming state, the AT gaming process S1912 is executed.

  In the AT gaming state S1912, operation information such as lever ON is received by a communication command. When the received combination information, particularly when the condition device of the push order small role group is standing, the effect for notifying the push order is set in the drawing queue so as to execute the effect for notifying the push order. In the AT game process S1912, if a predetermined number of games have been played as in the normal game process S1910, or if a chance zone is won by chance zone lottery, the chance zone win is temporarily stocked and put into the normal game state. When the transition is made, a process by winning the chance zone stocked in the normal game process S1910 is performed.

  The CPU 191 determines whether the current state is the chance zone 1 state (S1913), and determines whether the current state is the setting change state. If the current state is the chance zone 1 state, the chance zone 1 process S1914 is executed. The chance zone 1 process S1914 will be described later. Even in the chance zone 1 state in the chance zone 1 process S1914, the chance zone lottery may be performed.

  The CPU 191 determines whether the current state is the chance zone 2 state (S1915). If the current state is the chance zone 2 state, the chance zone 2 process S1916 is executed. The chance zone 2 process S1916 will be described later. Even in the chance zone 1 state in the chance zone 2 processing S1914, the chance zone lottery may be performed.

<7-1: Flow of Chance Zone 1>
FIG. 20 is an explanatory diagram showing the contents of the chance zone 1. The chance zone 1 determines whether or not to shift to the AT state within a predetermined number of games, specifically, according to the number of consecutive winnings of the specific combination within 10G. Here, the specific combination is a re-playing combination of the lottery group 12 and a rare small combination of the lottery groups 7 to 11. The rare specific combination having a low lottery probability among the specific combinations is a lottery group 7-11.

FIG. 20A is an explanatory diagram up to the AT winning by the consecutive winning of the specific role in the chance zone 1. The continuous winning number is reset to 0 at the start of the chance zone 1 (0 series). When the winning combination is other than the specific combination, that is, a combination belonging to the lottery groups 1 to 6, the number of consecutive winning combinations remains 0 (Y201). In the case of a specific combination, that is, a combination belonging to the lottery groups 7 to 12, the consecutive winning number is incremented by 1 (Y202 to Y204).

  If a winning combination other than the specific winning combination (lottery groups 1 to 6) is won by the consecutive winning count N = 3 when the AT winning is determined, the consecutive winning count becomes 0 (Y205 to Y206). Here, the number of consecutive winnings is 3, but the number of consecutive winnings may be any number as long as it is 2 or more.

  A specific example of a game in the chance zone will be described with reference to FIG. The selected lottery group numbers are shown at the top of the table. For example, the number “2” shown in the upper part of the table represents the lottery group 2.

  S2001 to S2010 each represent one game, and the time series progresses from left to right. Chance zone 1 is started from S2002. The lower part of the table shows the state (number of times) in which the specific combination continues. 0 series indicates that the winning combination of the specified role is not continuous, 1 series indicates that the specified role has been won once, 2 sets indicates that the specified role has been won twice in succession, and the confirmation is specified This indicates that the winning combination was won three times in succession, and as a result, the AT was won. After the chance zone 1 is started, the lottery result is the lottery group 2 in S2002, which is the 1st G, and therefore becomes 0 series. Since the lottery result was lottery group 3 in S2003, which is the 2G, it remains 0 series. Since the lottery result is the lottery group 7 in S2004 which is the 3G, since the lottery group 7 is a specific combination, it becomes a series. Since the lottery result is lottery group 8 in S2005, which is the 4G, the lottery group 8 is a specific combination, and therefore becomes a double. Since the lottery result is lottery group 4 in S2006, which is the 5th G, lottery group 4 is not a specific combination, so it becomes zero. Since the lottery result is the lottery group 7 in S2007, which is the 6Gth, the lottery group 7 is a specific combination, so it becomes a series. Since the lottery result is the lottery group 7 in S2008, which is the 7th G, the lottery group 7 is a specific combination, and therefore becomes a double. Since the lottery result is lottery group 7 in S2009, which is the 8th G, since lottery group 7 is a specific combination, the specific combination wins and is determined three times in succession. Since the chance zone is fixed at 10G, the remaining 2G remains, but since it is determined that the game state is to be shifted to the AT gaming state, the next game is shifted from S2010 to the AT state.

  Further, since the chance zone 1 remains, the process for AT winning may be performed until the number of games remaining in the chance zone 1 becomes zero, and the number of remaining games in the chance zone 1 becomes zero. If it is confirmed more than once, the winning AT will be stocked.

  On the condition of continuous winning, the number of points to be added may be drawn out (in accordance with the internal winning combination type), and when the number of points exceeds a certain value, it may be shifted to AT.

  FIG. 21 is an explanatory diagram showing the contents of a modification of the chance zone 1 of FIG. FIG. 21A is a diagram in which only one state is transferred in one game, but the state transfer destination is changed according to the result of the state transfer number lottery according to the type of the lottery group. FIG. 21B shows a table used in the state transition number lottery process for each type of lottery group.

  The lottery group 7 does not change to 2 state or 3 state, and only 100% 1 state is transferred. In the lottery group 8, there is no transition to 3 states, 80% is 1 state and 20% is 2 states. The lottery group 9 may shift from 1 to 3 states, 60% for 1 state, 30% for 2 states, and 10% for 3 states. The lottery group 10 does not shift to the 2 state, but shifts to the 1 state and the 10% 3 state at 90%. As with the lottery group 9, the lottery group 11 may transition from one to three states, with 70% being in one state, 20% being in two states, and 10% being in three states.

  FIG. 22 is a flowchart showing the contents of the chance zone 1 process S1914. In step S2201, it is determined whether or not combination information is transmitted by a communication command. If combination information is not sent, the process ends. If combination information is transmitted, the process proceeds to step S1402.

  The CPU 191 determines whether the specific combination is not continuous (S2202). The state in the chance zone 1 includes a state of how many specific roles are continued, and is independent of a game state such as a normal game, a two-type BB internal game, or a two-type BB game managed by the main board 100A. This state is not related to the state in the chance zone 1. It is determined whether or not the specific combination is in a zero-continuous state (S2202). If YES, the process proceeds to S2203, and if NO, the process proceeds to S2206.

  The CPU 191 determines whether or not the combination information is a specific combination (S2203). Specifically, it is determined whether or not the lottery group is 7 to 12 (S2203), and if it is the lottery group 7 to 12, the state is shifted to the single-running state and terminated (S2205). If it is not the lottery groups 7 to 12, the state is shifted to the 0-run state and terminated (S2204).

  The CPU 191 determines whether or not the specific combination is in a single continuous state in which the specific combination is continued only once (S2206). If YES, the process proceeds to S2207, and if NO, the process proceeds to 2210.

  The CPU 191 determines whether or not the combination information is a specific combination (S2207). Specifically, it is determined whether or not the lottery group is 7 to 12, and if it is the lottery group 7 to 12, the process proceeds to S2209, and the state is set to a two-run state. Transition to state and exit.

  The CPU 191 determines whether or not the specific combination is in a double state in which the specific combination is continued twice (S2210). If YES, the process proceeds to S2210, and if NO, the chance zone process is terminated.

  The CPU 191 determines whether or not the combination information is a specific combination (S2211). Specifically, it is determined whether or not the lottery group is 7 to 12. If the lottery group is 7 to 12, the process proceeds to S2213, and the sub gaming state is set to the AT state. If it is not the lottery groups 7 to 12, the process shifts to the 0-run state in S2212.

<7-2: Flow in Chance Zone 2>
FIG. 23 is an explanatory diagram for explaining the contents of the chance zone 2. The chance zone 2 is designed to increase the possibility of winning an AT according to a role other than the specific role. Compared with Chance Zone 1, the roles that are more advantageous than normal during the chance of winning an AT include all the roles that are not advantageous in Chance Zone 1, and the roles determined by internal lottery are Chance Zone 1 and Chance Zone 2 It always exists as a role that is always more advantageous than either of them. Therefore, the chance zone 2 is designed so that the possibility of winning an AT is increased according to a combination including a combination other than the specific combination. The rare specific combination having a low lottery probability among the specific combinations is a lottery group 7-11.

FIG. 23A shows a specific example of the chance zone 1. Each of S2301 to S2310 is an example of the result in the chance zone for each game, and the upper row shows the combination group numbers to be simultaneously won in the lottery divisions lottered by the internal lottery process. 1 represents lottery group 1, 2 represents lottery group 2, 3 represents lottery group 3, 4 represents lottery group 4, 5 represents lottery group 5, 6 represents lottery group 6, 7 represents Representing the lottery group 7, 8 representing the lottery group 8, 9 representing the lottery group 9, 10 representing the lottery group 10, 11 representing the lottery group 11, and 12 representing the lottery group 12.

The chance zone 1 is started from S2202. Since the lottery result is lottery group 2 in S2202, which is 1G after the chance zone 1 is started, the lottery based on the first point lottery table in FIG. Indicates that 1 point has been awarded.

  Since the lottery result is the lottery group 12 in S2203 which is the 2G, since there is no point in the point lottery table of FIG. 23B, no points are given, and the total point remains one point. Here, in the chance zone 1, the lottery table 12 was used as a specific role as an opportunity to execute a relatively advantageous AT lottery, but in the chance zone 2, there is an advantageous effect for the AT lottery. Not.

Since the lottery result is the lottery group 7 in S2204, which is the 3G, 2 points are drawn in the second point lottery table in FIG. It becomes a point (lower part of S2204).

Since the lottery result is lottery group 3 in S2205 which is the 4th G, 1 point is given by lottery in the first-stage point lottery table of FIG. It becomes a point (lower part of S2205).

Since the lottery result is the lottery group 12 in S2206, which is the 5th G, since there is no point in the point lottery table of FIG. 23B, no points are given and the total points remain at 4 points. (Lower stage of S2206).

Since the lottery result is lottery group 1 in S2207, which is the 6th G, 1 lottery is drawn in the first-stage point lottery table in FIG. It becomes a point (lower part of S2207).

Since the lottery result is lottery group 2 in S2208, which is the 7th G, 1 lottery is drawn in the first-stage point lottery table in FIG. It becomes a point (lower part of S2208).

Since the lottery result is the lottery group 7 in S2209, which is the 8th G, 2 points are given in the first-stage point lottery table in FIG. Points (S2209 bottom).

Since the lottery result is the lottery group 12 in S2210 which is 9G, since there is no point in the point lottery table of FIG. 23B, no points are given, and the total points remain 4 points. (Lower stage of S2209).

Since the 10th game becomes the last game in the chance zone 2, the AT lottery is performed with the lottery values corresponding to the points won in FIG. 23C using the points accumulated so far.

  Also, in principle, points are not awarded based on the winning combination in the 10th G, and the AT lottery is performed using the points accumulated so far, but the 10th G lottery results indicate the probability of winning as in the lottery groups 7-11. A privilege of adding points may be given when the role is low.

In the chance zone 2, as shown in FIG. 23B, the chance group 1 does not include the lottery group 12 that was a specific combination, and even if the specific combination is won, the chance zone 2 does not benefit at all.

In FIG. 23C, the higher the principle points, the higher the AT winning probability. However, when the total points are 0, a lottery table is used so that the AT winning is high. This also serves as relief when the chance zone ends with point 0, and the probability that the total point is 0 point is lower, so such a lottery table (FIG. 23C) is used. ing.

<Flow of chance zone 2>
FIG. 24 is a flowchart showing the flow of the chance zone 2.
The combination information is determined in S2401, and if the combination information has been updated, the process proceeds to S2402.

  In S2402, point lottery is performed according to the combination information, and the process proceeds to S2403.

  In S2403, a process of adding the points drawn in the point lottery is performed.

  In step S2404, it is determined whether the number of games is a predetermined number. This is performed to determine whether it is the final game in the chance zone 2. If it is the final game, the process proceeds to S2405, and an AT lottery corresponding to the points is performed. If it is not the final game, the chance zone 2 process is terminated.

  It is determined whether or not the AT is won in S2406. If YES is determined in S2406, the process shifts to S2407, and a process of shifting the current sub game state from the chance zone 2 state to the AT state is performed. If NO is determined in S2406, the process proceeds to S2408, and a process of shifting the current sub game state from the chance zone 2 state to the normal game state is performed.

  After performing the process of changing the sub gaming state to the AT state in S2407, the chance zone 2 process S1916 ends.

  After performing the process of setting the sub gaming state to the normal state in S2408, the chance zone 2 process S1916 ends.

  FIG. 25 is an explanatory diagram showing a screen for selecting a chance zone by the player's operation. An option 30a for chance zone 1 and an option 30b for chance zone 1 are displayed on the liquid crystal display device 30, and a selection effective frame 30c is displayed on the selected selection. The option 30a of the chance zone 1 corresponds to the chance zone 1, and the option 30b of the chance zone 2 corresponds to the chance zone 2.

  FIG. 25A shows an example in which a selection effective frame 30 c is displayed on the liquid crystal display device 30 on the option 30 a of the chance zone 1. When the bet button 11 is operated in this state, the chance zone to be selected is determined as the chance zone 1. When the predetermined time passes or the start lever 12 is operated, the screen shifts to the screen of FIG.

  FIG. 25B shows an example in which the selection effective frame 30 c is displayed on the liquid crystal display device 30 on the option 30 b of the chance zone 2. When the bet button 11 is operated in this state, the chance zone to be selected is determined as the chance zone 2. When the predetermined time passes or when the start lever 12 is operated, the screen shifts to the screen of FIG. Here, the bet button 11 and the start lever 12 are used as operation keys. However, for example, the stop buttons 13a to 13c may be used, and the bet button 11 and the start lever 12 may be reversed.

<8: Action effect>
In the combination lottery table of FIG. 8, there is no unfair election, and any one of the lottery groups 1 to 13 wins. In addition, after the RAM reset, the game state of the main board usually starts from the middle, but if the two-type BB is won, the game moves to the inside of the second-type BB and the game remains in the two-type BB internal state until the RAM is reset again. proceed. In such a case, after the winning flag setting process S105, one or more combinations of any of the internal lottery groups 1 to 12 are won. Therefore, there is no role in which the probability of AT lottery does not increase in Chance Zone 1 and Chance Zone 2 selected by the player, and it is always necessary to select the other chance zone retroactively when selecting a chance zone. It is possible to make the player think that the AT lottery has benefited from a lottery with a high probability. Therefore, the player can have a sense of expectation to select the chance zone, and therefore the player could not experience the high probability state of the AT lottery even if he selected the chance zone that was not selected. It is possible to prepare a chance zone that will not disappoint you.
