Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine that gives a probability-changing game after a big hit game when a game ball enters a specific area in the big hit game.

Conventionally, a pachinko machine that is a gaming machine determines whether or not to generate a big hit game based on a random value extracted due to the ball entering the starting port, and makes a big hit judgment with high probability. There is one that determines whether or not to give a probability variation game.
In this type of pachinko machine, when a big hit game is generated, it can be easily determined whether or not a probability variation game is given after the big hit game is finished, so the player's motivation is not when the probability variation is not There was a risk that it would not be able to increase the interest during the big hit game.

  Therefore, in recent years, in order to keep the player's interest until the end of the big hit game, the game board has two types of big prize outlets that have a specific area and a special area that does not have a specific area. The determination of the jackpot game is based on the random number value. Regarding the probability variation after the jackpot game ends, the basic mode operation of the jackpot game that opens the jackpot without the specific area is executed. There has been proposed a gaming machine that executes a condition mode operation of opening a special winning opening having a specific area, and determines whether or not to give a probability variation depending on whether or not a game ball has entered the specific area ( For example, see Patent Document 1 below).

Next, the operation of the pachinko machine 1 will be described.
The pachinko machine 1 performs a lottery determination of the usual figure due to the entry to the start gate 22 and starts the symbol variation of the ordinary figure display device 28A. If the lottery result is a win, the winning result is confirmed and displayed on the display device 28A, and the utility is released. This makes it possible to win the second special figure starting port 23B.
When there is a winning at the first or second special figure starting port 23A, 23B, a random number value is extracted due to this, and the special figure is determined based on the random value, and the special figure display device 27A and The symbol variation of the effect symbol display device 21 is started. If the determination result is a big hit, the big hit symbol is determined, the big hit symbol is determined and displayed on each of the display devices 21 and 27A, and the big hit game (special game) is executed. The effect symbol display device 21 displays a pseudo effect symbol corresponding to the special symbol.
The big hit game is a basic game in which a second round winning device 25 is opened and a predetermined time or an operation until the number of balls reached a predetermined number is closed as one round, and a predetermined number of rounds are continued. Then, if the first big winning device 24 is opened in a specific round during the big hit game, and there is a ball entering the V zone 240 of the first big winning device 24 in the specific round, the gaming state after the big hit game is changed. This is a basic configuration that shifts to a probabilistic change (probability change) game with a high probability of winning a jackpot and a time reduction (short time) game in which the win in the ordinary figure is high and the change time of the special figure is reduced.

Hereinafter, details of the operation will be described based on a program process executed by the main controller 40.
FIG. 6 shows a flowchart of a “main routine” executed by the main controller 40. The “main routine” is composed of this process (S100 to S110, S115) and the remaining process (S111), and has a cycle of 2 ms or 4 ms. It is started due to the interrupt signal, and it is first determined whether or not it is a normal interrupt (S100). This determination is made based on whether or not a specific numerical value is written at a specific address in the RAM. If the determination is negative (S100: no), the initial setting (S115) is executed. The numerical value for determining whether or not it is a normal interrupt is written in the RAM as part of this initial setting.

  If it is a normal interrupt (S100: yes), an initial value random number update process (S101), a big hit determination random number update process (S102) that is a random value for determining whether or not the special figure is correct, and an update of the special figure big hit symbol determination random number Process (S103), update process of random numbers for hitting determination of ordinary figure (S104), update process of random numbers for reach determination relating to reach of special figure (S105), update process of random numbers for determining variation pattern relating to fluctuation pattern of special figure ( S106), winning confirmation processing (S107), winning / failing determination processing (S108), each output processing (S109), fraud monitoring processing (S110) are performed, and the initial time is within the remaining time until the next interrupt signal is input. The random number update process (S111) is looped.

Next, a part of subroutines of the winning confirmation process (S107), the success / failure determination process (S108), and each output process (S109) which are deeply related to the present invention will be described.
The “start winning confirmation process” shown in FIG. 7 is a subroutine of the winning confirmation process (S107). If there is a ball entering the first and second special figure starting ports 23A, 23B (S200: yes), It is confirmed whether the hold memory is full (S201). In this embodiment, the number of pending storages that can be stored is four each.

  If the hold memory is not full (S201: no), in the extracted random number hold storage process of S202, a plurality of random number values (a big hit determination random number, a big hit symbol determination random number, and a reach determination use) extracted due to the above-mentioned incoming ball Random numbers, random numbers for determining variation patterns, etc.) are stored as reserved storage. In this process, the number of lights on the special figure hold number display device 27B is increased by one, and a special figure hold number command transmission process for transmitting the current hold storage number to the sub-integrating device 42 is performed. After the process of S202, the process returns.

  8 to 11 show flowcharts of the “win / fail determination process”. As shown in FIG. 8, in the “win / fail determination process”, first, the operation of the accessory continuous operation device is confirmed to determine whether or not a big hit game is being played (S300). no), it is confirmed whether or not the special figure is changing (S301). If it is not changing (S301: no), it is checked whether or not the fixed symbol of the special figure is being fixedly displayed (S302). ). If the special electric accessory is in operation (S300: yes), the process proceeds to “special game processing”.

  If the confirmed symbol is not being displayed in the process of S302 (S302: no), as shown in FIG. 9, it is confirmed whether or not there is a special figure pending storage (S310). If there is no pending storage (S310: no), the process proceeds to “special game processing”. If there is a reserved memory (S310: yes), the number of memories is subtracted and a shift process of the reserved memory is performed (S311). By the shift process, the oldest reserved memory among the reserved memories of the special figure is the target of the determination of success / failure.

Next, in the process of S312, the probability variation flag is confirmed to confirm whether or not the current gaming state is the probability variation gaming state (if the probability variation flag is “1”, the probability variation is in progress). If the probability change is in progress (S312: yes), it is determined whether or not it is a big hit by comparing the success / failure determination table at the time of the probability change with the big hit determination random number of the pending storage to be the target of the success / failure determination (S313).
If the probability change is not in progress (S312: no), it is determined whether or not it is a big hit by comparing the normal probability (low probability) determination table with the big hit determination random number (S314).

In the subsequent process of S315, it is confirmed whether or not the determination of whether or not the process of S313 or S314 is a big hit.
If it is a big hit (S315: yes), in the process of S316, the big hit symbol is determined based on the random number for determining the big hit symbol in the reserved storage that is the object of the determination.
In the process of S317, a variation pattern such as a variation time for a special figure jackpot displayed on the effect symbol display device 21 is determined based on the variation random number for determining the variation pattern of the reserved memory that is the object of the determination. Note that the processing of S315 corresponds to “win / fail judgment means” recited in the claims, and the processing of S316 corresponds to “design determination means”.

  After determining the variation pattern, a big hit setting process is performed in S318. In this process, a jackpot game release pattern is set based on the determined jackpot symbol. For example, the setting of the opening effect time of the jackpot game executed by the effect symbol display device 21, the setting of the time of the ending effect, the opening pattern of the jackpot game (total number of rounds, the first big winning device 24 or the second big winning device 25) And the like are set. The process of S318 corresponds to “open mode determining means” described in the claims.

  In the process of S315, if it is not a big hit but a loss (S315: no), a change pattern such as a change time for a special figure loss displayed on the effect symbol display device 21 is determined in the process of S319. In the subsequent lose setting process (S320), if the gaming state is a probability change, a probability change counter for counting the duration is subtracted.

  After each setting process of S318 or S320, in the process of S321, the symbol variation start control of the special symbol display device 26 is performed, and the symbol variation start command and the symbol designation command are transmitted to the sub integrated control device 42. Move to “Game processing”. The variation start command and the symbol designation command include a variation pattern of a special figure, a determination result of whether or not the special figure is appropriate.

  When the special symbol is changing in the process of S301 of FIG. 8 (S301: yes), as shown in FIG. 10, when it is confirmed that the symbol change time has passed (S330: yes), the fixed symbol display process In (S331), control is performed to end the special symbol variation display of the special symbol display device 27A, and the symbol confirmation is performed so that the sub-integrated control device 42 and the effect symbol control device 43 terminate the pseudo symbol variation display and the effect display. The command is transmitted, and the process proceeds to “special game processing”.

If the confirmed symbol of the special figure is being displayed in the process of S302 of FIG. 8 (S302: yes), the process proceeds to S340 of FIG. 11 and it is confirmed whether or not the confirmed symbol display time has ended. If the fixed symbol display time has not ended (S340: no), the process proceeds to "special game processing".
On the other hand, when it is confirmed that the fixed symbol display time has ended (S340: yes), the final symbol display of the special symbol display device 27A is controlled to be ended by the final symbol display end processing (S341), and the sub-integration is performed. A command is transmitted to the control device 42 so as to end the fixed display of the pseudo symbol corresponding to the special figure.

  Subsequently, it is confirmed whether the symbol of the special figure is a combination that is a big hit (S342). If the combination is a big hit (S342: yes), if the probability variation flag is “1” (S343: yes), “0” is set to the probability variation flag (S344). Next, if the hour / hour flag is “1” (S345: yes), “0” is set to the hour / hour flag (S346). By these processes, the gaming state in the big hit game (special game) is reset to the normal state.

In the process of S347, the operation of the condition device is started, and in the process of S348, the operation of the accessory continuous operation device is started. The condition device is a device that is necessary for the operation of the continuous action device in the jackpot game, and the continuous accessory operation device is a device that continuously operates the special electric accessory.
Then, a command is sent to the sub integrated control device 42 to start the big hit effect by the big hit start effect process (S349), and the process proceeds to the “special game process”.

If the combination is not a big hit in the process of S342 (S342: no), it is confirmed whether the probability variation flag is “1” (S350), the probability variation flag is “1” (S350: yes), and the probability variation counter ( If the (number of times) is “0” (S351: yes), the probability variation flag is set to “0” (S352).
In the subsequent process, if the hour / hour flag is “1” (S353: yes) and the hour / hour counter (number of times) is “0” (S354: yes), the hour / hour flag is set to “0” (S355).
In the subsequent state designation command transmission process of S356, a state designation command including information on a probability change flag indicating a gaming state and a time reduction flag is transmitted to the sub integrated control device. Thereafter, the process proceeds to “special game processing”.

As shown in FIG. 12, in the “special game processing”, first, it is confirmed whether or not the accessory continuous operation device is in operation (S400). If it is in operation (S400: yes), “probability change” described later in the processing of S401 is performed. Perform “entrance passage confirmation processing”. In S400, if the accessory continuous operation device is not operating (S400: no), the process returns.
In the process of S402 following the process of S401, it is confirmed whether or not the big prize opening of the first big entry device 24 is open. If not (S402: no), the second big entry device 25 is large. It is confirmed whether the winning opening is open (S403). If not open (S403: no), it is confirmed whether the interval is in progress (S404). If it is not during the interval (S404: no), it is confirmed whether the big hit end effect is being performed (S405). If it is not during the big hit end effect (S405: no), it is confirmed whether the big hit start effect time has elapsed (S406). If the big hit start effect time has elapsed (S406: yes), in the big prize opening opening process of S407, the first or second big prize winning device 24, 25 set in the process of S318 of the “win / fail judgment process”. Is opened, and an opening count for counting the number of times the first or second big winning devices 24, 25 are opened is added in the process of S408, and the process returns.

  If the big prize opening of the first big prize winning device 24 is open in the process of S402 (S402: yes), as shown in FIG. 13, the big prize winning opening of the first big prize winning device 24 in the processes of S415 and S416 is performed. Confirm whether or not there are ten winnings, which is the prescribed number of winnings, or whether or not the opening time of the big winning opening has ended. It closes (S417), executes a big hit interval process (S418), and returns. In the big hit interval process, a command is transmitted to the effect symbol control device 82 and the sub integrated control device 83 so as to start the big hit interval effect.

  If the opening time has not expired in the process of S416 (S416: no), it is confirmed whether the sorting blade accessory (sorting blade member 241) is closed (S419). If the distribution blade member 241 is closed (S419: yes), it is confirmed whether or not a first predetermined time (4 seconds) has elapsed since the opening of the big winning opening of the first big winning device 24 (S420). When the passage of the first predetermined time is confirmed (S420: yes), the sorting blade member opening process is executed to open the sorting blade member 241 (S421). Then return.

  If the big winning opening of the second big prize winning device 25 is open in the process of S403 (FIG. 12) (S403: yes), as shown in FIG. 13, the second big prize winning device 25 in the processes of S410 and S411 is performed. It is confirmed whether or not there are ten winnings that are the prescribed number of prizes in the grand prize winning opening, or whether or not the opening time of the big winning prize has expired. Is closed (S412), a big hit interval process is executed (S413), and the process returns.

  If it is during the interval in the process of S404 (FIG. 12) (S404: yes), it is checked whether the big hit interval time has elapsed in the process of S430 of FIG. 14, and if it has elapsed (S430: yes), the release counter By the last round (final R, the 9th round of “opening pattern A” and “opening pattern B” described later, or “opening pattern C”, “opening pattern D”, “opening pattern E”, “opening pattern F” 15th round) (S431), and if it is the final round (S431: yes), the jackpot end effect processing (S432) is executed, and in this process, the effect symbol control device 82 and the sub integrated control device A jackpot end command is transmitted to 83. Then, the release counter is cleared (S433), the big hit game is finished and the process returns.

On the other hand, if it is not the final round in the process of S431 (S431: no), a specific round (specific R, the ninth round of “open pattern A” and “open pattern B” described later), or “open pattern” is determined by the open counter. It is confirmed whether it is a round immediately before the 9th and 15th rounds of “C”, “Open pattern D”, “Open pattern E”, and “Open pattern F” (S434). If the round immediately before the specific R, that is, if the next round is the specific R (S434: yes), the big winning opening opening process (S435) of the first big winning device 24 is executed, and the opening counter is added. At the same time (S436), the probability variation entrance valid flag is set to “1” to validate the V zone 240, and the player can enter the probability variation by entering the V zone 241 (S437). Then return.
If it is not the round immediately before the specific R in the processing of S434 (S434: no), the big winning opening opening process (S438) of the second big winning device 25 is executed, and the opening counter is added (S436). ), Return.

If the big hit interval time has not elapsed in the processing of S430 (S430: no), the round of the specific R (“opening pattern A” and “opening pattern B” described later) is performed by the open counter in the processing of S440 of FIG. Or 9th and 15th rounds of “open pattern C”, “open pattern D”, “open pattern E”, “open pattern F”), and if it is a specific R (S440: yes) ), It is confirmed whether or not the V zone 240 is valid based on the probability variable entry valid flag (S441). If it is valid (S441: yes), it is confirmed whether 2 seconds (corresponding to the “third predetermined time” in the claims) has elapsed since the end of the round (S442), and if it has elapsed (S442: yes). ), The probability variation entry valid flag is cleared (S443), and the process returns.
If 2 seconds have not elapsed in the processing of S442 (S442: no), it is confirmed whether 1 second (corresponding to “second predetermined time” in the claims) has elapsed since the end of the round (S444). If so (S444: yes), the closing process (S445) of the sorting blade member 241 is executed, and the process returns.

  If the big hit end effect is in the process of S405 (FIG. 12) (S405: yes), as shown in FIG. 16, it is confirmed whether the big hit effect end time has passed (S450), and if it has passed (S450). : Yes), the operation stop processing (S451) of the accessory continuous operation device, and the operation stop processing (S452) of the condition device are executed.

In the subsequent processing of S453, it is confirmed whether or not the probability variation valid flag is “1”. The probability variation valid flag is a flag that is set to “1” when there is a ball entering during the valid period of the V zone and the transition to the probability variation is determined. If the probability variation valid flag is “1” (S453: yes), the probability variation / short time counter setting process (S454) for setting the probability variation and the short duration is performed (S454), and the probability variation / short time flag is set to “1” ( S455), the probability variation valid flag is cleared (S456). The process of S454 corresponds to “probability changing means” described in the claims.
Thereafter, a big hit game end command is transmitted to the effect symbol control device 82 and the sub integrated control device 42 (S457), and a state designation command is transmitted to the sub integrated control device 42 and the like. Then return.

  The “probability change entrance passage confirmation process” shown in FIG. 17 is a process of confirming the entry into the V zone 241 in the winning confirmation process (S107) subroutine executed by the main controller 40. First, it is confirmed whether the probability variation valid flag is “0” (S500). If the flag is “0” (S500: yes), the probability variation entry valid flag is “1” and the V zone 240 is valid. (S501).

  If the V zone 240 is valid (S501: yes), it is confirmed whether there is a ball entering the V zone 240 (probability entrance) (S502), and if there is a ball (S503: yes), the probability variation valid flag. Is set to “1”, and it is decided to shift to the probability variation game.

As shown in FIG. 18 (a) and FIG. 19, the pachinko machine has “hit / hit symbols A” to “hit” as the big hit symbols determined in the special symbol big hit symbol determination process of the “win / fail determination process” (FIG. 8). Six types of symbol groups (groups) of “big hit symbol F” are set, and six types of patterns “open pattern A” to “open pattern F” are set corresponding to each big hit symbol. FIG. 19 shows a special figure displayed on a special figure display device 27A composed of a 7-segment display. A plurality of special figures are set in each of the symbol groups of “big hit symbols A to F”. For example, “big hit symbol A” is “symbols 1 to 7”, “big hit symbol D” is “symbols 22 to 28”, and the like.
The jackpot symbol between each symbol group is a different symbol but is similar, especially between “open pattern A” and “open pattern B”, between “open pattern A, B” and “open pattern D”, “Open patterns A, B, D” and “open pattern F” are set to be similar. For example, “symbol 1” and “symbol 9” between “open pattern A” and “open pattern B”, and “symbol 3” and “symbol 11” between “open pattern A, B” and “open pattern D”. And “symbol 27” are similar to “symbol 7”, “symbol 8”, “symbol 24” and “symbol 40” between “open pattern A, B, D” and “open pattern F”.

  As shown in FIG. 18B and FIG. 20, “open pattern A” and “open pattern B” have 9 rounds of jackpot game rounds, the 9th round (the final round, 1st round ”), the first big winning device 24 is opened and a decision is made as to whether or not to proceed with certainty. The “opening pattern A” allows the first grand prize winning device 24 to be open for 28 seconds and allows the change of probability change. On the other hand, “open pattern B” has an open time of 1 second and does not allow a change in probability. The “big hit symbol A” corresponds to the “first symbol group” in the claims, and the “open pattern A” corresponds to the “first opening mode” in the claims. On the other hand, “big hit symbol B” corresponds to “second symbol group” in the claims, and “open pattern B” corresponds to “second open mode”.

“Open pattern C” to “open pattern F” have a total of 15 rounds, the 9th round and the 15th round (the last round, which corresponds to the “second specific round” in the claims). The first grand prize device 24 is opened in the round. In “Open Pattern C”, the opening time of the first big prize winning device 24 is 28 seconds in any round, and in “Open Pattern D” and “Open Pattern E”, either the 9th round or the 15th round Since the opening time of the first big prize winning device 24 is 28 seconds, the transition of the probability change is allowed. On the other hand, the “opening pattern F” does not allow a certain change in the opening time of 1 second in any round. The “big hit symbol D” corresponds to a “third symbol group” in the claims, and the “open pattern D” corresponds to a “third release mode” in the claims. On the other hand, “big hit symbol F” corresponds to “fourth symbol group” in the claims, and “open pattern F” corresponds to “fourth open mode”.
The “hit symbol C”, “open pattern C”, “hit symbol E”, and “open pattern E” do not correspond to the claims, but “fifth symbol group” and “fifth symbol”, respectively. A mode ", a" sixth symbol group ", and a" sixth open mode ". The symbols are set to be similar between “open patterns A, B, D, F” and “open pattern C”, and between “open patterns A, B, C, D, F” and “open pattern E”. Yes.

  As shown in FIG. 20 and FIG. 21, in the “opening patterns A and B”, the big hit game is ended by the end of the ninth round, but in the “opening patterns C to F”, the tenth round is started after the ninth round. The Rukoto. In this case, the time from the start of the ninth round to the start of the tenth round is constant regardless of whether the release time of the ninth round is “open patterns C, E” or “open patterns D, F” with a short release time. .

As shown in FIG. 21, in the jackpot game of any of the “open patterns A, C, E”, the first symbol winning device 24 enters the V zone 240 in the effect symbol display device 21 from the start of the ninth round. The display ("Fig. 22A") of "V-entry hitting effect A" is executed (stimulating).
When there is an entry into the V zone 240 and the probable entrance SW detects this, the “V entry strike effect A” is stopped, and a V entry is made to the effect symbol display device 21 based on the entry into the V zone 240. The display of the suggested “V entry effect” (FIG. 22C) is executed. The display of “V-entry effect” ends when the ninth round of “opening patterns A, C, E” ends.
In addition, since “open pattern C, E” has 10 rounds or more, even if the “V entry effect” is continued, another display suggesting that V entry has been made may be performed, and after 10 rounds. It is also desirable to make a suggestion of V entry.

On the other hand, in the jackpot game of any of the “open patterns B, D, F”, the effect symbol display device 21 starts to hit the V zone 240 of the first big winning device 24 from the start of the ninth round (prompt). ) The display of “V-entry ball production effect B” (FIG. 22A) is executed.
Since there is no V entry in the jackpot game of any of “open patterns B, D, F”, “V entry strike effect B” has its effect display time determined in advance, from the end time of the ninth round It is set a little longer. When the “V-entry effect B” is completed, the “V non-entry effect” display (FIG. 22B) is executed. The display of “V non-entering effect” ends at the same time as the end of the ninth round of “open pattern A, C, E”.
In addition, since there are 10 rounds or more in the “open patterns D and F”, even if the “V non-entry effect” is continued, another display suggesting that the V has not entered may be performed. It is desirable to suggest V non-entry even after 10 rounds.

  In each of the “Open Patterns A to F”, the big hit game is continued in the 10th round, together with the above-mentioned “V-entry effect A, B, V-entry effect, V non-entry effect”, etc. It may be possible to display the “continuous hitting effect” of the big hit game such as whether or not (FIG. 23A). “Continuous beat production” is displayed until the end of the ninth round of “opening patterns A to F”, and is “opening pattern A, B” where the big hit game ends in the ninth round to the player? Gives a sense of expectation and thrill as to whether it is an “open pattern C to F” that lasts up to 15 rounds. It should be noted that the “continuous hitting effect” is desirably displayed alternately with “V-entry hitting effects A, B, V-entry effect, V non-entering effect” and the like.

In the jackpot game of “open pattern C to F”, the effect symbol display device 21 is displayed at the end of the ninth round of “open pattern C, E” at the end of the ninth round or at the same time. The display of the “big hit continuation effect” indicating the continuation of the big hit game (FIG. 23B) is executed.
On the other hand, in the jackpot game of “open pattern A, B”, at the end of the ninth round of “open pattern A” or at the jackpot end interval performed at the same time, the jackpot game is ended on the effect symbol display device 21. The display of “big hit end effect” (FIG. 23C) is executed.

  The distribution blade member (distribution blade member) 241 has opened the “opening patterns B, D, F” from the start of opening the large winning opening of the first large winning device 24 in the ninth and fifteenth rounds ( The opening operation is performed after the elapse of the first predetermined time (4 seconds) of 1 second or more, and the V zone 240 is substantially opened by moving from the restriction position to the allowable position. This is because the opening time of the 9th round of the “opening pattern B, D, F” and the 15th round of the “opening pattern E, F” is 1 second, and the game that entered the first grand prize winning device 24 during that time. In order to prevent the ball from entering the V zone 240, a state where the V can be entered by the sorting blade accessory 241 is made 4 seconds after the start of the ninth and fifteenth rounds.

  In any of the “open patterns A to F”, the second predetermined time (from the time of closing the big winning opening of the first big winning device 24 in the long opening corresponding to “open patterns A, C, E” ( Closes after 1 second). This is 1 from the end of the ninth and fifteenth rounds so that game balls that have entered the first grand prize winning device 24 just before the end of the ninth and fifteenth rounds can enter the V zone 240. For a second, a state where a V entry can be made by the sorting blade accessory 241 is provided, and a margin for the V entry is provided. (It should be noted that the prize winning device role is designed so that the maximum time required for entering the first zone winning device 24 and entering the V zone 240 is less than 1 second.)

  In addition, the probability variation entrance valid flag is set to “1” at the start of opening of the big prize opening of the first big prize winning device 24 in the ninth and fifteenth rounds, and the first big prize winning device 24 in the long opening is won. It is reset after the elapse of a third predetermined time (2 seconds) from when the mouth is closed, and during this time, the V zone 240 is made valid. The effective period of the V zone 240 has a margin more than the closing of the first grand prize winning device 24 and further the closing of the V zone 240 by the sorting blade accessory 241.

  FIG. 22 shows an example of a display mode of effects related to entering the V zone 240. FIG. 22A shows an example of the “V prize winning effects A and B”. In any of the “open patterns A to F”, at the start of the ninth round, the screen of the effect symbol display device 21 displays 9 A round display 210 indicating the round, a main character display 211, and a telop display 212 for hitting a ball entering the V zone 241 such as “Please enter V before the big prize opening closes” are displayed.

  Since it is impossible to enter the V zone 240 in the “open patterns B, D, F”, the “V non-entering effect” shown in FIG. 22B is performed. In this effect, a main character display 211 of a crying face and a telop display 212 indicating that a certainty such as “sorry ...” has not been obtained are displayed.

  When there is an entry to the V zone 240 in the “open pattern A, C, E” and the probability change is determined, the “V entry effect” shown in FIG. 22 (c) is performed. A character display 211 and a telop display 212 indicating that a probability change such as “Did you get it?” Are displayed.

  Next, FIG. 23 shows an example of the display mode of the effect related to the big hit continuation. The “continuous roaring effect” shown in FIG. 23A shows an example of an effect display performed together with the “V non-entrance effect” of the crying face in the “open pattern B, D, F”. A display 211 and a telop display 212 such as “Continue a big hit if you stop crying” are displayed.

When the big hit game continues after the ninth round in the “open pattern C to F”, the “big hit continuation effect” shown in FIG. 23B is performed, and the main character display 211 of the normal face and “continue! A telop display 212 indicating that the big hit game such as “!” Continues is displayed.
On the other hand, if it is “open pattern A, B” and the big hit game ends in nine rounds, the “big hit end effect” shown in FIG. 23 (c) is performed, and the main character display 211 of a crying face and “sorry, A telop display 212 such as “End” is displayed.

  In the “open pattern C, E”, since the transition to probability change is confirmed at the end of the ninth round, it is not necessary to make the main character display 211 a crying face when performing the “continuous hitting effect” of the big hit game. It is desirable to display the display mode of FIG. 23 (b) following the display mode of FIG. 22 (c).

  FIG. 24 shows an example of a display mode of the V zone entry effect in the 15th round in the “open patterns D and F”. At the start of the fifteenth round, as shown in FIG. 24 (a), a telop display 212 that suggests entering the V zone 241 such as "Last chance. Enter V before closing the big prize opening" is displayed. .

In the “open pattern F”, it is impossible to enter the V zone 240 even in the fifteenth round. Therefore, after the first big winning device 24 is closed, as shown in FIG. Then, a telop display 212 indicating that the certainty such as “sorry ...” has not been obtained is displayed.
On the other hand, when there is a ball entering the V zone 240 in the “open pattern D” and the probability change is determined, the main character display 211 of the joy face is shown in FIG. 24C after the first big winning device 24 is closed. Then, a telop display 212 is displayed to indicate that the probability change such as “Did you get it?” Is obtained.

  Since it has already been decided that “open patterns C and E” will shift to probability change, at the start of the 15th round, as shown in FIG. 25, a joy face main character display 211 and a telop such as “probability confirmed” are displayed. It is desirable to make display 212.

  According to the present embodiment, the first big winning device 24 having the V zone 240 and the second big winning device 25 having no V zone are provided, and the first big winning device 24 is opened in a specific round of the big hit game and the V Depending on whether or not a game ball enters the zone 240, it is determined whether or not to shift to a promising after the big hit game, and it is easy to enter the first big winning device 24 according to the big hit symbol. Combined with the fact that a big hit game opening pattern and a difficult opening pattern are provided, and the big hit symbol is similar between both patterns so that the player can not judge which pattern it is when a big hit occurs, It is possible to maintain the motivation of the player during the jackpot game, such as whether or not the probability change is obtained, and to enhance the interest during the jackpot game.

As the opening pattern of the big hit game, one or both of the first special winning devices 24 of the first and second specific rounds (9R, 15R) such as “opening patterns A, C, D, E” are opened. A pattern with a long time (28 seconds) and a pattern with a short opening time (1 second) of the first big winning device 24 of the first and second specific rounds such as “open patterns B and F” are provided. .
Further, the first grand prize winning device 24 is provided with a sorting blade member 241 for restricting the entry of game balls into the V zone 240, and a predetermined time (4 seconds) has elapsed since the start of the specific round (9R, 15R). Until that time, it is configured to restrict the entry into the V zone 240, and the predetermined time is longer than the opening time of the first big winning device 24 of the “opening pattern B, F”.
With these configurations, “open patterns A, C, D, and E” allow probability fluctuations, but “open patterns B and F” do not allow probability fluctuations, and “open patterns B and F”. ", It is possible to prevent fraudulent acts such as using a magnet or the like to illegally change.
The “opening patterns A, C, D, E” allow the transition to probability change, and the opening time of the first big winning device 24 is long, and the ball enters the V zone 240 naturally. Don't worry.

  Furthermore, since an effective period for validating the entry into the V zone 240 is provided, it is possible to prevent fraud in which the probability change is obtained more reliably and to open the effective period for the first first prize winning device 24. Since the time is longer than the time, it is possible to eliminate the missed probability change in the “open patterns A, C, D, E”.

In addition, as the opening pattern of the big hit game, a pattern with a small number of rounds (9 rounds) such as “opening patterns A and B” and a large number of rounds such as “opening patterns C, D, E, and F” (15 rounds). ) Provide a pattern.
In the “open patterns C, D, E, F”, the first grand prize winning device 24 is opened in the ninth round (first specific round) as in the “open patterns A, B”.
Furthermore, in “Open Pattern A” and “Open Patterns C and E”, the open time of the first big winning device 24 in the ninth round is the same time, and in “Open Pattern B” and “Open Patterns D and F” The opening time of the first grand prize winning device 24 in the ninth round is the same time.
Whether the winning pattern is “opening pattern A” or “opening pattern B”, whether the winning pattern is “opening pattern A” or “opening pattern B”.
It is not possible to distinguish between “open pattern A”, “open pattern C, E”, “open pattern B”, or “open pattern D, F”, and the player has any open pattern. A thrilling feeling and expectation can be given. Further, if it is made indistinguishable whether it is “open pattern A”, “open pattern D, F”, “open pattern B” or “open pattern C, E”, it will be more interesting. Can be improved. That is, if the big hit game is completed in the ninth round, it is one of “opening patterns A and B”, and not only winning balls but also “opening pattern B” cannot be expected. On the other hand, if it progresses to the next round, it will be one of “open patterns C, D, E, F”, and of course the prize ball, as well as “open patterns C, E” will increase the player's expectation for probability fluctuations. Therefore, the interest during the big hit game can be further improved.

  In the “open pattern C, D, E, F”, as in “open pattern C, D, E”, the first large one of the first and second specific rounds (9R, 15R) or both.
