Description

  The present invention relates to a ball game machine that plays a game by firing a game ball on a game board.

  Conventionally, in a pachinko machine that is a ball game machine, a lottery is performed based on the game ball launched on the game board entering a specific starting port, and the lottery result is confirmed and displayed on the symbol display device. If the lottery result is a big hit, there is a case where the openable winning opening is opened and the game shifts to a special game (big win game) advantageous for winning a prize ball. In addition, this type of pachinko machine is configured to shift to a probable game with a high probability of winning the winning lottery after the special game, based on the big hit symbol at the time of winning.

Pachinko machines have different winning probabilities depending on the manufacturer and machine type, and the winning probabilities are high, but the number of winning balls at one big hit is low and the gambling is low. There are many award winning balls and high gambling characteristics, and the player can select the machine base according to his / her preference.
In addition, with the conventional pachinko machines, game shop employees and players will win the probability of winning big hits with the aim of broadening the player's choice and providing a game that can be enjoyed by many players from beginners to veterans. Has been disclosed (see, for example, Patent Document 1).
In addition, in the pachinko machine disclosed in Patent Document 1, in addition to changing the winning probability setting, it is possible to change the setting of the number of rounds of the big hit game, the ratio of the probability change game after the end of the big hit game, the limiter that ends the probability change game, etc. It is said.

Japanese Patent Laid-Open No. 10-57583

By the way, in the conventional pachinko machine that can change the winning probability setting, in order to avoid the confusion of the game processing due to the change of the probability setting and the winning at the starting port, the game ball is stopped in a low probability state. The setting can be changed when there is no start prize.
However, with a conventional pachinko machine, the winning probability setting can be changed when there is a player's ball, such as a memory of unpaid winning balls. If the probability setting is changed when there is a player's ball, the expected value at which a prize ball can be obtained changes for one game ball that is a ball. For example, a game beginner likes a game with a low expected value and a low gambling ability, and if the game becomes a game with a high expectation value and a high gambling characteristic due to a change in the winning probability during the game, the beginner invests unplannedly. There was a problem that it suffered a disadvantage.
Therefore, in view of the above circumstances, the present invention has been made to realize a bullet ball game machine in which the expected value of one game ball is not changed by changing the winning probability setting, and the disadvantage of the player is reduced. It is a thing.

According to the first aspect of the present invention, a predetermined number of game balls are enclosed inside, a prize ball acquired by winning a prize is added to the stored number of possessed balls, and the enclosed within the range of the number of possessed balls A ball game machine that uses a game ball in a circular manner to play a game,
A winning / losing lottery means for executing a winning / failing lottery due to a ball entering a starting port provided on the game board, and a special game that shifts to a special game advantageous for winning a prize ball if the result of the winning / failing lottery is winning. In a ball game machine comprising execution means, backup means for backing up the stored contents of the RAM before power-off, and clear means for clearing the backed-up stored contents by turning on a RAM clear signal,
Providing a probability setting change means for enabling the setting change of the winning probability of the winning / losing lottery,
A condition for changing the setting of the probability setting changing means is that the RAM clear signal is ON.

  According to the invention described in claim 1, since it is possible to change the setting of the winning probability of the special game by the probability setting changing means on the condition that the RAM clear signal is ON, the game is played after the setting change of the winning probability. In order to start, the player must purchase a new game ball (held ball), and the expected value for one game ball as a held ball is prevented from changing. Therefore, for a game beginner who prefers a game with a low expectation value for one game ball and a low gambling ability, the game does not have a higher expectation value and gambling ability than the probability setting change means. It is possible to reduce the disadvantage of the player, such as avoiding it.

When a predetermined prize exchange operation is performed by the prize processing device 31, a prize exchange receipt is issued, and a desired prize is handed over to the player in exchange for a prize exchange receipt at a service counter or the like.

Next, the operation of the pachinko machine 50 will be described.
The pachinko machine 50 performs a lottery determination for the usual figure by entering the starting gate 21 and starts the symbol variation of the ordinary figure display device 18. If the lottery result is a win, the winning symbol of the ordinary figure is confirmed and displayed on the display device 18 to release the ordinary utility. As a result, it is possible to enter the second special figure starting port 22B.
When there is a ball entering the first special figure starting port 22A, the first special figure is determined by lottery, and the first special figure display device 16A and the effect symbol display device 15 start changing the symbols. If the lottery result is a big hit, the big hit symbol (special game) with the opening of the big winning opening 25 is executed by definitely displaying the big hit symbol on each of the display devices 15 and 16A.
Similarly, if there is a ball in the second special figure starting port 22B, the second special figure is determined whether or not to win, and the second special figure display device 16B and the effect symbol display device 15 start symbol variation. If the lottery result is a big hit, the big hit symbol (special game) with the opening of the big winning opening 25 is executed by definitely displaying the big hit symbol on each of the display devices 15 and 16B. The effect symbol display device 15 displays a pseudo symbol or effect corresponding to the first or second special symbol.
If there is a ball entering the first or second special figure starting port 22A, 22B during the symbol variation, the first or second special figure is stored on hold according to the ball entered. When there is a hold of the second special drawing, the variation of the second special drawing and the lottery determination are executed in preference to the first special drawing.
After the jackpot game is over, the probability variation state in which the winning probability is high according to the symbol at the time of the jackpot, and / or the variation time of the special symbol is shortened, and the utility model (second special diagram starting port 22B) When the opening time is extended, it is possible to shift to a short state.

  The outline of the “main routine” of the program processing executed by the main controller 80 will be described with reference to FIG. The “main routine” is composed of the main processing (S100 to S111, S115) and the remaining processing (S112). The main routine is started due to an interrupt signal having a period of 2 ms or 4 ms, and first determines whether the interrupt is normal. (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 (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 random number update process (S101), a big hit determination random number update process (S102), a big hit symbol determination random number update process (S103), a normal hit determination random number update process (S104), update processing of random numbers for determination of hitting symbols for ordinary drawings (S105), update processing of random numbers for reach determination regarding reach of special symbols (S106), update processing of random numbers for determination of variation patterns regarding variation patterns of special symbols ( S107), winning confirmation process (S108), winning / failing determination process (S109), each output process (S110), fraud monitoring process (S111), and the initial time within the remaining time until the next interrupt signal is input The random number update process (S112) is looped.

Next, a part of subroutines of the winning confirmation process (S108), the success / failure determination process (S109), and each output process (S110) which are deeply related to the present invention will be described.
The “start winning confirmation process” shown in FIG. 6 is a subroutine of the winning confirmation process (S108). First, it is confirmed whether or not there is a ball entering the first special figure starting port 22A (S200), there is a ball (S200: yes), and the reserved memory of the first special figure is not full (S201: no), In the process of S202, a plurality of types of random numbers (such as a jackpot determination random number, a jackpot symbol determination random number, a reach determination random number, a variation pattern determination random number, etc.) relating to the first special figure are extracted, and are mainly stored as a reserved memory of the first special figure. It is stored in the memory of the control device 80 (maximum 4). And the first special figure hold display device 1
A command for the number of first special figure reservations is transmitted to the display control of 7A and the effect symbol control device 82 and the sub integrated control device 83.

Subsequently, it is confirmed in the process of S203 whether there is a ball entering the second special figure starting port 22B. If there is a ball (S203: yes), and the reserved memory of the second special figure is not full (S204: no). ), A plurality of types of random numbers (such as a big hit determination random number, a big hit symbol determination random number, a reach determination random number, a variation pattern determination random number, etc.) relating to the second special figure are extracted in the process of S205, and the second special figure is stored on hold. Are stored in the memory of the main controller 80 (maximum of four). Then, the display control of the second special figure hold display device 17B and the command of the second special figure hold number are transmitted to the effect symbol control device 82 and the sub integrated control device 83. The processing in S202 and S205 corresponds to the start storage means described in the claims.

  7 to 11 show a flowchart of the “win / fail determination process”. As shown in FIG. 7, the “win / fail determination process” confirms whether the special electric accessory for opening the special winning opening 25 is in operation, and if it is not in operation (S300: no), the symbol (first or second) (2 special figure) is checked to see if it is changing. If it is not changing (S301: no), it is checked whether the confirmed symbol of the first or second special figure is 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. 8, it is confirmed whether there is a reserved memory of the second special figure (S310). If there is a hold memory of the second special figure (S310: yes), the number of the hold memories of the second special figure is subtracted, and the hold process of the second special figure is shifted (S311). By the shift process, the oldest stored memory among the stored memories in the second special figure becomes the target of the determination of success / failure.
If there is no reserved memory for the second special figure (S310: no), it is checked whether there is a reserved memory for the first special figure in S312, and if there is a reserved memory for the first special figure (S312: yes), the first special figure is obtained. The number of reserved memories in the figure is subtracted, and the shift process of the reserved memory of the first special figure is performed (S313). As a result, the oldest reserved memory among the reserved memories of the first special figure becomes the target of the determination of success / failure.
In this way, by confirming the reserved memory of the second special figure before the reserved memory of the first special figure, the success / failure lottery of the second special figure is prioritized over the lottery determination (correction determination) of the first special figure. To be executed. If neither the second special chart or the first special chart is stored on hold (S312: no), the process proceeds to "special game processing".

Next, in the process of S314, the probability variation flag is confirmed to confirm whether the current gaming state is in the probability variation (high probability) (if the probability variation flag is 1, the probability variation is in progress). If the probability change is in progress (S314: yes), the success / failure determination table at the time of the probability change is compared with the big hit determination random number of the hold memory that is the target of the determination of success / failure to determine whether or not it is a big hit (S315).
If the probability change is not in progress (S314: no), whether or not it is a big hit is determined by comparing the normal probability (low probability) hit determination table with the big hit determination random number (S316).

In the subsequent process of S317, it is confirmed whether or not the determination of whether or not the process of S315 or S316 is a big hit. The process of S317 corresponds to the winning / not-lotting means described in the claims.
If it is a big hit (S317: yes), in the process of S318, the big hit symbol is determined based on the random number for determining the big hit symbol in the reserved memory that is the object of the determination.
In the subsequent process of S319, the winning variation pattern is determined based on the variation random number for determining the variation pattern of the reserved storage that is the object of the determination.

In the process of S320, a mode of jackpot game (a mode of opening the jackpot 25) is assigned based on the determined jackpot symbol. For example, a mode in which the 28-second opening of the special winning opening 25 is performed 15 rounds, a mode in which the 6.0-second opening of the large winning opening 25 is performed two rounds, or the like is assigned.
Also, in this process, based on the jackpot symbol and the game state (probability change state, short time state) at the time of determination, whether or not to give a probability change after the big hit game, whether to give a short time Set up. In addition, in the case of assigning a certain change or time reduction, the limit number is also set. The limited number of times is set, for example, such that the number of successful lottery times of the first and second special drawings is counted, and when the count value reaches a predetermined value, the probabilistic change and the time reduction are terminated. Of the jackpot symbols, the symbols that are considered to be probable are called probabilistic symbols.

  If it is not a big hit in the process of S317 but a loss (S317: no), a process of determining a fluctuation pattern is performed in S321 based on the random number for determining the fluctuation pattern of the pending storage that is the object of the determination. Loss setting processing is performed in the processing of S322.

  After the big hit setting process of S320 or the loss setting process of S322, in the process of S323, the first special symbol display device 16A or the second special symbol display device 16B is subjected to the symbol variation start control, and the effect symbol control device 82 and the sub-integration are performed. A symbol change start command is transmitted to the control device 83, and the process proceeds to "special game processing". The variation start command includes a lottery result such as a variation pattern of a special figure and a prize winning opening game lottery.

  When the first special figure or the second special figure is changing in the process of S301 of FIG. 7 (S301: yes), as shown in FIG. 9, when it is confirmed that the change time of the symbol has passed (S330: yes) ), In the fixed symbol display process (S331), the variation end of the special symbol of the first special symbol display device 16A or the second special symbol display device 16B, and the pseudo symbol variable display on the effect symbol control device 82 and the sub integrated control device 83 A command is transmitted so as to end the game, and the process proceeds to “special game processing”.

If the confirmed symbol of the first special figure or the second special figure is being displayed in the process of S302 of FIG. 7 (S302: yes), as shown in FIG. 10, it is confirmed whether or not the confirmed symbol display time has ended (S340). ). 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 first special symbol or the first special symbol display device 16A or the second special symbol display device 16B or the first special symbol display device 16B by the fixed symbol display end setting process (S341). The final symbol display of the second special figure is terminated, and a command is transmitted to the effect symbol control device 82 and the sub-integrated control device 83 so as to terminate the confirmation display of the pseudo symbol corresponding to the first special figure or the second special figure. .

  Subsequently, it is confirmed whether the symbol of the first special figure or the second special figure is a big hit combination (S342). If it is a big hit combination (S342: yes), if the probability variation flag is 1, ( S343: yes), the probability variation flag is set to 0 (S344). Next, if the time reduction flag is 1 (S345: yes), 0 is set in the time reduction flag (S346).

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 effect symbol control device 82 and the sub integrated control device 83 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 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 is 0 (S353: 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 such as a probability change flag indicating a gaming state and a time reduction flag is transmitted to the effect symbol control device 82 and the sub integrated control device 83. Thereafter, the process proceeds to “special game processing”.

As shown in FIG. 11, in the “special game processing”, first, it is confirmed whether or not the accessory continuous operation device is in operation (S500). If it is in operation (S500: yes), the winning prize opening 25 is processed in S501. Check if is open. In S500, if the accessory continuous operation device is not operating (S500: no), the process returns.
If the big winning opening is not open in the process of S501 (S501: no), it is confirmed whether it is during the interval (S502), if not during the interval (S502: no), it is confirmed whether the big hit end effect is being performed (S503), If it is not during the jackpot end effect (S503: no), it is confirmed whether the jackpot start effect time has elapsed (S504). If the jackpot start effect time has elapsed (S504: yes), the winning prize opening process of S505 is performed. Then open the grand prize opening 25 and return.

  If the big prize opening is being opened in the process of S501 (S501: yes), as shown in FIG. 12, it is confirmed whether or not there are nine prizes that are the prescribed number of prizes in the big prize opening 25 (S510), or It is confirmed whether or not the opening time of the big prize opening 25 has ended (S511), and if either can be confirmed, the big prize opening 25 is closed (S512), the big hit interval process is executed (S513), and the process 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 it is during the interval in the process of S502 of FIG. 11 (S502: yes), it is confirmed whether the big hit interval time has elapsed in the process of S514 of FIG. 12, and if it has elapsed (S514: yes), it is the final round. Confirmation (S515), if it is the final round (S515: yes), the big hit end effect processing (S516) is executed, and the big hit end command is transmitted to the production symbol control device 82 and the sub integrated control device 83 by this processing. Then, the big hit game ends and returns.
On the other hand, if it is not the final round (S515: no), the process of releasing the special winning opening 25 (S517) is executed and the process returns.

  If the big hit end effect is in the process of S503 in FIG. 11 (S503: yes), as shown in FIG. 13, it is confirmed whether the end time of the big hit end effect time has passed (S520), and if it has passed ( S520: yes), a process (S521) for stopping the operation of the accessory continuous operation device is executed, and a process (S522) for stopping the operation of the condition device is executed.

  Subsequently, in the process of S523, the contents of the jackpot setting set in the process of S320 (FIG. 8) are referred to, the probability variation count (probability variation counter) setting processing (S524), the time reduction count (time reduction counter) setting processing (S525). )I do. Next, a variation table setting process is performed (S526).

Further, if the game state after the big hit game is surely changed and the time is short, the probability change flag is set to 1 (S527), and the time reduction flag is set to 1 (S528). Setting the probability change flag to 1 shifts to the probability change state after the special game ends, and setting the time reduction flag to 1 shifts to the time reduction state after the special game ends.
Thereafter, a jackpot game end command is transmitted to the effect symbol control device 82 and the sub-integrated control device 83 (S529), and information indicating whether or not the high-probability gaming state is in the open extension is transmitted as a state designation command. (S530). It is configured to return later. The processes in S505 and S517 correspond to special game execution means described in the claims, and the process in S527 corresponds to probability changing means.

Next, the setting change of the winning probability of the special figure will be described.
The setting change of the winning probability is fundamentally changed from the winning probability (low probability) in the normal game, unlike the probability change that occurs after the jackpot game ends in the flow of the game. In this embodiment, as shown in FIG. 14, for example, a plurality of types of setting values “1 to 6” are provided in advance, and according to each setting value, a low probability, a probability variation pattern ratio, and a high probability at the time of probability variation. The winning probability setting is changed by selecting one set value. In addition, the ratio of the probability variation pattern is a ratio that varies from the big hit.
For example, in “setting value 1”, the low probability is set to “1/430”, and the probability is low, and the ratio of the probability variation symbol is set to “7/15” so that the probability is easily changed by the big hit.
On the other hand, in the “set value 5”, the low probability is set to “1/250”, and the probability is high, so that the probability variation pattern ratio is set to “2/15”, so that the probability is not easily changed due to the big hit. Furthermore, since the big hit is likely to occur, the high probability is set to a probability lower than that of “set value 1”.
In addition, with “set value 6”, there is no probability variation setting because the low probability is “1/200” and the probability is quite high.

FIG. 15 shows the “fixed setting change process 1” executed by the main control device of the pachinko machine 50. In this process, first, it is confirmed whether or not a game is currently being played (S600). If the game is in progress (S600: yes), the process returns.
On the other hand, if the game is not in progress (S600: no), the first or second special figure holding memory (starting memory) indicating that there has been a ball entering the first or second special figure starting port 22A, 22B. It is confirmed whether or not there is (S601).

If there is a start memory in the process of S601 (S601: yes), the process returns.
On the other hand, if there is no start memory (S601: no), it is confirmed whether or not there is a ball (prize ball) stored in the storage means of the main controller 80 (S602).

If there is a ball storage in the process of S602 (S602: yes), the process returns.
On the other hand, if there is no possessed ball memory (S602: no), it is confirmed whether or not a setting change operation for the winning probability of the special figure has been performed in the setting device 87 (S603).

If the operation of changing the setting of the winning probability of the special figure has not been performed in the process of S603 (S603: no), the process returns.
On the other hand, if the setting change operation has been performed (S603: yes), the setting value is read from the setting device 87 (S604), and the low probability and probability change for winning the special figure based on the read setting value. A symbol ratio and high probability setting change process is performed (S605). The low probability, the probability variation pattern ratio, and the high probability of the setting change are stored in the storage medium of the main controller 80. The process of S605 corresponds to the probability setting changing unit described in the claims.

  Thereafter, the main control device 80 transmits the winning probability setting change and the newly set winning probability to the table management device 94 via the sub integrated control device 83 and the external connection terminal (S606). ). Thus, the sub integrated control device 83 and the table management device 94 that have received the setting change display that the winning probability setting has been changed by various display devices and the new winning probability is displayed. The low probability, the probability variation pattern ratio, and the high probability of setting change in subsequent games are reflected in the game.

  According to the present embodiment, a predetermined number of game balls are enclosed in the pachinko machine, and the enclosed game balls are cyclically fired on the game board to perform the game. The start storage means for storing the start memory in response to the ball entering the start opening, the success / failure lottery means for executing the success / failure lottery of the special figure based on the start memory, and a prize if the result of the success / failure lottery is a winner In an enclosed pachinko machine comprising special game execution means for shifting to a special game with a special figure advantageous for acquiring a ball, and possession ball storage means for storing a prize ball that has not been paid out as a possession ball. Probability setting changing means is provided to enable setting change of the winning probability of the winning / no-win lottery in the figure, the probability setting changing means is not playing a game, the starting memory of the starting storage means is not stored, and The ball storage means of the ball storage means And enabling execution of the setting change of winning probability on condition that it is not 憶. Therefore, to change the winning probability, the player's ball must be lost, and to start the game after the setting is changed, the player must purchase a new game ball (held ball). Therefore, the expected value for one game ball of the possession ball is prevented from changing. As a result, for a game beginner who prefers a game with a low expected value for one game ball of the possession ball and a low gambling property, the game is not a game with a higher expected value and a higher gambling property than the setting change means, and an unplanned investment in the game beginner It is possible to reduce the disadvantage of the player, such as not having to play.

  In the present embodiment, even if the gaming state is in the probability changing state, the setting device 87 is configured to change the winning probability of the special figure. In this case, based on the setting value set by the setting device 87, the low probability, the probability variation pattern ratio, and the high probability are respectively changed. Of course, the setting change must satisfy the conditions of S600, S601, and S602 of “Setting Change Processing 1” (FIG. 15). To start the game after the setting is changed, the player changes to the newly purchased ball. Therefore, the expected value for one game ball of the possession ball does not change.

In the first embodiment, the winning probability setting change of the special figure is processed between games. Alternatively, the winning probability setting change may be performed when the power is turned on. Hereinafter, a configuration for changing the winning probability setting when the power is turned on will be described as a second embodiment.
In the present embodiment, the pachinko machine 50 according to the first embodiment is configured to perform the power-on process shown in FIG. The basic configuration of this embodiment is the same as that of the first embodiment.

  As shown in FIG. 16, when the power is turned on, the main controller 80 completes the security check and is permitted to access the RAM (S800). If the RAM clear signal is on (S801), the backup flag is set. Based on whether it is on (S802), it is determined whether to start the pachinko machine from the initial state (S803 to S811) or to start the pachinko gaming machine from the state before power-off (S812 to S813).

  If the RAM clear signal is ON in S801 (S801: yes), or if the backup flag is not ON in S802 (S802: no), stack setting processing (S803), RAM work area clear processing (S804) is executed to initialize the work area (S805). Subsequently, command data for displaying an initial screen is transmitted to the effect symbol display device 15 (S806), and command data for displaying initial decorations of various LEDs and lamps is transmitted to the sub-integrated control device 83. (S807).

  Next, in step S808, a setting value is read from the setting device 87, and a special probability winning probability, a probability variation symbol ratio, and a high probability setting change process are performed based on the read setting value ( S809). The low probability, the probability variation pattern ratio, and the high probability of the setting change are stored in the storage medium of the main controller 80.

Thereafter, the main control device 80 transmits the winning probability setting change and the newly set winning probability to the table management device 94 via the sub integrated control device 83 and the external connection terminal (S810). ). Thus, the sub integrated control device 83 and the table management device 94 that have received the setting change display that the winning probability setting has been changed by various display devices and the new winning probability is displayed.
Thereafter, the normal processing is performed (S811).

  If the backup flag is ON in the process of S802 (S802: yes), this means that the RAM retains the storage contents before the power is shut off, and the power recovery process is executed (S812). Based on the information indicating the state of the gaming machine, the game progress program suspended due to the occurrence of a power failure is resumed (S813).

  According to this embodiment, there exists an effect similar to the said 1st Embodiment. In addition, since the winning probability setting change process is performed when the power is turned on and the RAM is cleared, the desired probability can be set at the time when the game hall starts business.

  A third embodiment will be described with reference to FIGS. As shown in FIG. 17, the pachinko machine 50A of this embodiment includes an upper plate 62 and a lower plate 63, sets game balls purchased from the CR unit 56 on the upper plate 62, and launches these game balls onto the game board. And play a game. The upper plate 62 is provided with a payment display device 59, a ball rental SW 57 and a payment SW 58. When the game progresses and the upper plate 62 is filled with the prize ball, the prize ball is paid out to the lower plate 63. When the lower plate 63 is full, the payout of the prize ball is stopped and the unpaid prize ball is held as a holding ball. Stored in the sphere storage means.

As shown in FIG. 18, this pachinko machine is provided with a payout control device 81, and in connection with this, a payout relay terminal board is lent and a ball break SW, payout motor, payout SW, full SW, etc. are provided. In this pachinko machine, the main controller 80 is connected to the hall computer of the game hall via the external connection terminal board 78. The other electrical configuration is almost the same as that of the pachinko machine of the first embodiment.

The basic configuration of the software relating to the game control of the pachinko machine is almost the same as that of the pachinko machine of the first embodiment, and the differences will be mainly described.
In the present pachinko machine, the “probability setting change process 2” shown in FIG.

In the “probability setting change process 2”, first, it is confirmed whether or not a game is currently being played (S610). If a game is being played (S610: yes), the process returns.
On the other hand, if the game is not in progress (S610: no), the first or second special figure holding memory (starting memory) indicating that the first or second special figure starting port 22A, 22B has been entered. It is confirmed whether there is any (S611).

If there is a start memory in the process of S611 (S611: yes), the process returns.
On the other hand, if there is no start memory (S611: no), it is checked whether or not there is a ball (prize ball) stored in the storage means of the main controller 80 (S612).

If there is a ball storage in the process of S612 (S612: yes), the process returns.
On the other hand, if there is no possessed ball memory (S612: no), it is confirmed whether or not there is a game ball on the upper plate 62 by a sensor provided on the upper plate 62 (S613).

If there is a game ball on the upper plate 62 in the process of S613 (S613: yes), the process returns.
On the other hand, if there is no game ball on the upper plate 62 (S613: no), it is confirmed by a sensor provided on the lower plate 63 whether or not there is a game ball on the lower plate 63 (S614).

If there is a game ball on the lower plate 63 in the process of S614 (S614: yes), the process returns.
On the other hand, if there is no game ball in the lower plate 63 (S614: no), it is confirmed whether or not the setting change operation for the winning probability of the special figure has been performed in the setting device 87 (S615).

If the operation for changing the setting of the winning probability of the special drawing has not been performed in the process of S615 (S615: no), the process returns.
On the other hand, if a setting change operation has been performed (S615: yes), a setting value is read from the setting device 87 (S616), and a low probability and probability change for winning the special figure based on the read setting value. A symbol ratio and high probability setting change process is performed (S617). The low probability, the probability variation pattern ratio, and the high probability of the setting change are stored in the storage medium of the main controller 80.

  Thereafter, the main control device 80 transmits the winning probability setting change and the newly set winning probability to the table management device 94 via the sub integrated control device 83 and the external connection terminal (S618). ). Thus, the sub integrated control device 83 and the table management device 94 that have received the setting change display that the winning probability setting has been changed by various display devices and the new winning probability is displayed. The low probability, the probability variation pattern ratio, and the high probability of setting change in subsequent games are reflected in the game.

  According to this embodiment, the same effect as the first embodiment can be obtained. In particular, since it was possible to change the winning probability setting on the condition that there are no game balls on the upper plate and the lower plate, the player must purchase a game ball to start the game after the setting change, The expected value for one game ball does not change.

  It should be noted that the present invention is not limited to the embodiments described above, and can of course be implemented in various ways without departing from the gist of the present invention. For example, the effect button 67 and the jog dial 68 may be used as a setting device for changing the winning probability setting, or a setting device may be provided in the information disclosure device.
