Description

  The present invention relates to a probability variation type pachinko machine that changes the winning probability of a lottery executed during the progress of a game in accordance with the gaming state, and in particular, a game at the time of opening a store without imposing an excessive burden on the gaming store. It is related with the means to raise the interest of the person.

  In the case of a conventional probability variation type pachinko machine, when the player turns on the power (when the RAM data of the control unit is backed up, the RAM data is initialized, the same applies hereinafter), the player is given a profit by lottery. The probability of winning the jackpot is set to a low probability (for example, 1/300), and after winning the jackpot and a predetermined condition is satisfied, the probability of winning the jackpot by lottery is high (for example, , 1/30) (for example, see Patent Document 1). FIG. 18 is a diagram illustrating a change in the probability of winning a jackpot in a conventional probability variation type pachinko machine. When RAM data is initialized, the probability of winning a jackpot is set to a low probability. The probability of winning the jackpot shifts to a high probability by winning per probability change, and if you win continuously per probability change, the probability of winning the jackpot remains high, so you win the so-called normal win The probability of winning a jackpot shifts to a low probability.

At the amusement store, the pachinko machine is turned on at the preparatory stage before the store is opened, and the RAM data is initialized when the power is turned on. The game is started from a state where the probability of winning is low.
Japanese Patent No. 2719714

  In this way, in the conventional probability variation type pachinko machine, even when entering the store at the same time as opening the store and starting the game, no special privilege is given to the player, so until the first jackpot is won In some cases, a large amount of money must be invested in between, and as a result, it is difficult to continuously attract the player's interest, and the availability of pachinko machines cannot be increased.

  Such a problem can be solved by increasing the probability of winning the lottery when the power is turned on, but if the probability of winning the lottery is simply increased, a large amount of money can be invested with a small amount of money. As a result, the game store will have a heavy burden and cannot be adopted at all.

  The present invention has been made in view of the actual situation of the prior art, and a probabilistic type pachinko machine that can enhance the interest of the player at the time of opening the store without placing an excessive burden on the game store. It is intended to provide.

  In order to achieve the above-mentioned object, the present invention firstly, the opening time of the grand prize opening is triggered by a winning opening and a big prize opening provided on the game board surface, and a winning of a game ball to the starting opening. If the winning combination of a plurality of types with different winnings is determined and one of the plurality of types of winning is won as a result of the lottery, the opening / closing control of the big prize opening is performed in a manner corresponding to the winning type. A control unit, the control unit in a lottery that is triggered by winning a game ball to the start opening when a memory that sequentially stores various data that changes as the game progresses is initialized As a result of winning the winning probability of the winning / succeeding lottery with respect to the winning so that the winnings of the plurality of types are won with high probability, The when the opening time of the special winning hole is won shortest time per Is the probability of winning the lottery of spruce about the plurality of types per performed thereafter to the structure to shift to a low probability.

  The control unit is provided with a memory (RAM) for sequentially storing various data that change as the game progresses. Based on a random number counter stored in the RAM, the opening time of the big prize opening is The lottery of the success or failure regarding different types of hits is performed. Therefore, if the RAM data is set so that these lotteries are won with high probability when the power is turned on during preparations for opening the store, the player can enter a small amount of money when entering the store and starting the game at the same time. Since the opening time of the big prize opening is long and it becomes easy to win the kind of hit (big hit) where a lot of prize balls are paid out, it becomes easy to attract the player's interest. On the other hand, in the state where the RAM is initialized, not only the winning / losing lottery, but also the winning time of the winning prize opening is the shortest, and the winning of the winning ball can hardly be expected, for example, the success / failure of sudden probability change (surprise) When the lottery is performed together, and when the winning lottery is suddenly changed, if the winning probability of the winning lottery that is to be performed subsequently is changed from a high probability to a low probability, the success or failure of the jackpot is determined at a relatively early stage after the game starts. Since the winning probability of the lottery can be shifted from a high probability to a low probability, the burden on the amusement shop side can be reduced.

  Secondly, in the pachinko machine having the first configuration, the present invention further includes a symbol display unit that is display-controlled by the control unit, wherein the control unit determines whether or not to win a plurality of types of hits performed thereafter. When the winning probability is shifted to a low probability, the symbol display section does not display that the winning probability of the lottery has shifted from a high probability to a low probability.

  If a lottery is suddenly won, the winning prize opening will be opened and closed for a predetermined number of times, so that the player can see the probability of winning a big hit in the next lottery from a high probability to a low probability. However, in this case, the opening and closing operation of the grand prize opening is small and the opening time of the big prize opening is also short, so the player's impression is rare, and the player However, it is rare to stop playing the pachinko machine after seeing the opening and closing operation of this prize winning opening. However, if the probability that the jackpot is won in the next lottery is displayed on the symbol display section indicating that the probability shifts from a high probability to a low probability, the player is strongly impressed that the advantageous gaming state has ended, so the pachinko machine It's easy to lose interest in continuing the game in the game, and to stop playing the pachinko machine. Therefore, the player's interest in the pachinko machine can be linked by not performing display on the symbol display unit.

  Thirdly, in the pachinko machine having the first configuration, the present invention further includes a symbol display unit that is display-controlled by the control unit, and the control unit starts a game in a state where the memory is initialized. After that, until the winning time for winning the winning hole other than the shortest time is won, the winning time for winning the winning hole will be won for the shortest time and will be performed after the winning time. In the lottery, even when the probability of winning for each of the plurality of types is changed from a high probability to a low probability, the symbol display section displays that the winning probability of the lottery has been changed from a high probability to a low probability. It was not configured.

  If you win a lottery such as sudden change without winning a jackpot lottery, and if the probability of winning a jackpot decreases from a high probability to a low probability, it will be displayed on the symbol display section, the player As a result, the player's interest in the pachinko machine can be linked by not performing display on the symbol display unit. However, after winning the jackpot once, even if the probability of winning the jackpot in the next lottery shifts to a low probability, it will only be in the same gaming state as when the probability change state ended in the conventional probability change type pachinko machine Therefore, even if a display indicating that the winning probability of winning the jackpot is low is performed on the symbol display section, the result does not remarkably detract from the player's interest. Therefore, after winning the jackpot once, it can be displayed on the symbol display section that the winning probability of the jackpot has become low.

  Fourthly, the present invention has a high probability of winning the winning lottery and the winning lottery for the winning, with the start opening and the big winning opening provided on the game board surface and the winning of the game ball to the starting opening as an opportunity. A control unit that performs opening / closing control of the big prize opening in a manner corresponding to the winning winning when the winning is determined as a result of the lottery, When the memory that sequentially stores various data that changes with the progress of the game is initialized, the winning is won with high probability in the lottery performed with the winning of the game ball at the start opening As described above, the winning probability of the winning lottery with respect to the winning becomes a high probability, and when the winning lottery for shifting the winning probability of the winning lottery from the high probability to the low probability is performed, It was constructed to shift the probability of winning the lottery of spruce on the hit to the low probability.

  This configuration is an application of the present invention to a pachinko machine of a type that performs a lottery of success or failure that shifts the winning probability of a winning lottery from a high probability to a low probability, that is, a pachinko machine of a type that performs a lottery of falling, When a lottery for a fall is won, the winning probability of the winning / losing lottery to be performed thereafter is shifted to a low probability. Also with this configuration, it is possible to achieve a balance between the profit of the player and the profit of the game store when entering the store at the same time as opening the store and starting the game.

  Fifth, in the pachinko machine having the fourth configuration, the present invention further includes a symbol display unit that is display-controlled by the control unit, wherein the control unit wins the winning lottery probability related to the subsequent win Is shifted to a low probability, the symbol display unit is configured not to display that the winning probability of the lottery has shifted from a high probability to a low probability.

  As a result of winning the lottery of falling, when the probability of winning a jackpot in the next lottery is shifted from high probability to low probability, if this is displayed on the symbol display section, the player can play the game with that pachinko machine Since it is easy to stop, the player's interest in the pachinko machine can be linked by not performing display on the symbol display unit.

  Sixthly, in the pachinko machine having the fourth configuration, the present invention further includes a symbol display unit that is display-controlled by the control unit, and the control unit starts a game in a state where the memory is initialized. After that, until the winning of the winning, the winning probability of the winning lottery is won in the lottery that shifts from the high probability to the low probability, and the probability of winning the winning in the lottery performed after the winning is determined. Even when the probability shifts from a high probability to a low probability, the symbol display section does not display that the winning probability of the lottery has shifted from a high probability to a low probability.

  As a result of winning the lottery of falling, even if the probability of winning the jackpot without ever winning the jackpot has decreased from a high probability to a low probability, the result of suddenly winning the lottery of the chance change will not win the jackpot Just as if the probability of winning the jackpot has dropped from a high probability to a low probability, at least until the first jackpot is won, the symbol display will indicate that the probability of winning the jackpot has dropped from a high probability to a low probability. By not displaying, it is possible to connect the player's interest in the pachinko machine.

  The pachinko machine of the present invention performs a lottery performed when the probability of winning the jackpot lottery is high and the game ball is won at the start opening in the initialization state of the memory provided in the control unit. As a result, when a lottery of sudden change or fall is won, the probability of winning the jackpot lottery in the subsequent lottery shifts to a low probability, so that the interest of the player immediately after opening can be remarkably increased and the game The burden on the store side can be reduced, and the profit of the player and the profit of the game store can be balanced.

The values of various parameters for controlling the are stored.

  The RAM 120 temporarily stores input / output data for the CPU 110, data for arithmetic processing, various counters including a random number counter related to the game, and the like, and has a holding memory area and stores information on each holding ball. . The RAM 120 stores the control command scheduled to be output in a predetermined area, and when the power is restored from the power failure, the contents of the RAM 120 are restored to the state immediately before the power failure, and the control command scheduled to be output from the RAM 120 is output to shut off the power. Return the gaming state to the previous state.

  The CPU 110 detects the detection signals of the switches 21 to 24 taken in through the input port 150 according to the program stored in the ROM 130, various parameters stored in the ROM 130, time measurement of the timer 140, various data stored in the RAM 120, etc. And a required command or signal is output to the start port opening / closing device 31, the big prize opening / closing device 32, the effect control unit 200, the payout control unit 300, and the hall computer via the output port 160. More specifically, the CPU 110 performs a lottery of a special symbol and a lottery of a normal symbol, and performs drive control of each part according to the lottery result. The special symbol lottery and the regular symbol lottery are random numbers used for lottery for determining whether or not to win the winning state for a plurality of presets (predetermined random numbers), and reach lottery for whether or not to reach A random number update process that updates random numbers to be used, random numbers to determine the type of symbols to be displayed, and random numbers necessary for game control, etc., and a number according to the winning probability per each within the numerical range of the winning random numbers The winning value is set, and the CPU 110 determines whether or not the input winning random number value matches the winning value. If it matches, it is won, and if it does not match, it is lost.

  As with the main control unit 100, the effect control unit 200, the symbol control unit 210, the indicator light control unit 220, the voice control unit 230, the payout control unit 300, and the launch control unit 400 are also CPU, ROM, RAM, input port, and output. Consists of including ports. Thus, by providing a plurality of control units, the load on the main control unit 100 can be reduced, and complex control can be processed at high speed.

  When the power supply unit 500 detects that the voltage of the power supply line that supplies power to the entire main control unit 100 has become equal to or lower than a predetermined voltage value, the power supply unit 500 outputs a power-off signal indicating that the power supply has been cut off to the CPU 110. To do. Further, when a power cut is detected, the power line is switched from a power line that supplies power to the entire main controller 100 to a power line that is directly connected to the CPU 110. As a result, power is supplied to the RAM 120 from the power supply line directly connected to the CPU 110, so that information can be held. In addition, a RAM clear switch 501 is attached to the power supply unit 500. When a power switch (not shown) is turned on while the RAM clear switch 501 is turned on, data stored in the RAM 120 sequentially as the game progresses. Is cleared and the RAM 120 is initialized. In the pachinko machine according to the present embodiment, when the RAM 120 is initialized, the probability of winning a prize for giving a profit to a player in a special symbol lottery becomes high. Note that the initialization of the RAM 120 is normally performed at a preparatory stage before opening the store.

  Hereinafter, the lottery that accompanies winning of the game ball to the start port 3 executed by the main control unit 100 will be described. The pachinko machine according to the present embodiment performs five types of lottery shown in FIG.

  In FIG. 4, the jackpot number 1 is 15 rounds, the opening time of the big winning opening 4 per round is 30 seconds, the maximum number of winning game balls to the big winning opening 4 per round is nine, The probability of winning in the winning lottery performed after the winning process ends is high.

  In FIG. 4, the jackpot 2 is 15 rounds, the opening time of the big winning opening 4 per round is 30 seconds, and the maximum number of winning game balls to the big winning opening 4 per round is nine. The probability of winning in the winning lottery performed after the winning process ends is low.

  When winning these jackpots 1 and 2, the effect symbol display device 2 and the special symbol display unit 5 display the effect symbols and special symbols indicating which jackpot is won, and notify the player. . When these big hits 1 and 2 are won, in the winning process, a large amount of game balls are paid out to the player as prize balls.

  In FIG. 4, the sudden probability change is 2 rounds, the open time of the big winning opening 4 per round is 0.9 seconds, and the maximum number of winning game balls to the big winning opening 4 per round is nine. Thus, the probability of winning in the winning lottery performed after the winning process ends is low.

  In FIG. 4, the sudden working time is 2 rounds, the open time of the big winning opening 4 per round is 0.9 seconds, and the maximum number of winning game balls to the big winning opening 4 per round is 9 Thus, the probability of winning in the winning lottery performed after the winning process ends is high.

  In the case of winning a lottery of sudden probability change or sudden reduction of time, the effect symbol display device 2 and the special symbol display unit 5 may or may not display the effect symbol and the special symbol indicating which one has been won. You can also. Also, until winning the first jackpot 1, 2, even if it wins suddenly abruptly or suddenly does not display on the production symbol display device 2 and the special symbol display unit 5, after winning the first jackpot 1, 2 In addition, it is possible to make a configuration in which the effect symbol display device 2 and the special symbol display unit 5 display that the sudden probability change or the sudden time saving is won. When winning suddenly or suddenly, the winning opening 4 is set shorter than the jackpots 1 and 2, so more specifically, the number of rounds is small and the winning slot in one round is more detailed. Since the opening time of 4 is set short, the player cannot acquire a large amount of game balls.

  In FIG. 4, the fall is a state in which the RAM 120 is initialized or won, and the probability of winning in the lottery performed when the game ball is won at the start port 3 is high. When winning the lottery, the probability of winning in the winning lottery shifts from a high probability to a low probability.

  Although five types of lottery are shown in FIG. 4, the type of lottery is not limited to this, and can be increased or decreased as needed.

  Hereinafter, using the lottery performed with the winning of a game ball at the starting port 3 as an opportunity, the probability of winning the winning lottery is shifted from a high probability to a low probability, or from a low probability to a high probability. The play specifications of the pachinko machine according to the above will be described.

<First Embodiment>
A first embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart showing the game specifications of the first embodiment, and FIG. 6 is a timing chart showing the timing at which the winning probability in the game specifications of the first embodiment shifts from a high probability to a low probability or from a low probability to a high probability. It is. The game specification of the first embodiment is based on the winning probability of winning at the timing when a lottery of a, b, and c shown in FIG. Is shifted from a high probability to a low probability, and the effect symbol display device 2 is not notified of whether the gaming state is in a high probability state or a low probability state.

  When the RAM 120 is initialized when the power is turned on, the CPU 110 sets a high probability of winning in the win (step S101).

  Next, the process proceeds to step S103, where it is determined whether or not there is a game ball winning at the start port 3, in other words, whether or not there is a special symbol winning hold, and there is a special symbol winning hold. In step S104, a lottery for winning a, b, and c shown in FIG. 4 is executed with the probability set in the CPU 110 (step S104). If it is determined in step S103 that there is no special symbol winning suspension, the process waits until there is a winning game ball at the start port 3.

  After the lottery, it is determined whether or not a win is made (step S105). If it is determined that no win is made, that is, if it is determined that the game is “out of”, the process proceeds to step S103. Return. If it is determined in step S105 that it has been won in some way, the process proceeds to step S106, where it is determined whether or not a sudden chance change has been won. After moving to step S107 and performing the process in the case of winning the sudden probability change shown in FIG. 4, the probability of winning the win is shifted to a low probability (step S108). Thereafter, the process returns to step S103.

  If it is determined in step S106 that there is no sudden probability change, the process proceeds to step S109, and it is determined whether or not the jackpot 2 lottery is won. If it is determined in step S109 that the jackpot 2 lottery has been won, the process proceeds to step S110, and the processing for winning the jackpot 2 shown in FIG. 4 is executed. Transition is made (step S111).

  In step S109, if it is determined that the jackpot is not 2, the process proceeds to step S113, and after performing the process of winning the jackpot 1 shown in FIG. 4, the probability of winning the prize is maintained at a high probability. (Step S114).

  Therefore, in the gaming specifications of the first embodiment, as shown in FIG. 6, the probability of winning the winning lottery is high when the power is turned on (when the RAM 120 is initialized) and suddenly changes in this state. When winning the lottery and when winning the jackpot 2 lottery, it shifts from high probability to low probability, and with the transition to low probability, when winning the lottery 1 lottery, low probability to high probability Migrate to

  The game specification in this example initializes the RAM 120 when the power is turned on and sets a high probability of winning in the win, so if the player enters the store at the same time as opening the store and starts the game, it will start with a small amount of funds. It will be easier to win a big hit and encourage players to visit. On the other hand, in the game specification of this example, when the random selection lottery is suddenly won in the state where the RAM 120 is initialized, the winning probability of the lottery to be performed thereafter is shifted from a high probability to a low probability. At a relatively early stage after the start, the winning probability of winning the lottery can be shifted to a low probability, and the burden on the game shop side can be reduced. Furthermore, in the state where the RAM 120 is initialized, if the winning lottery suddenly wins and the winning probability of winning the lottery shifts from a high probability to a low probability, the display of the effect symbol display device 2 is not changed. Without strongly impressing that the gaming state advantageous to the player has ended, the player's interest in the pachinko machine can be connected, and the operating rate of the pachinko machine can be increased.

Second Embodiment
A second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a flowchart showing game specifications of the second embodiment. The game specifications of the second embodiment are based on the winning probability of winning at the timing when a lottery of a, b, and c shown in FIG. Is changed from a high probability to a low probability, and the effect symbol display device 2 is notified whether the gaming state is in a high probability state or a low probability state.

  As shown in FIG. 7, the game specification of the second embodiment adds steps S102, S112, S115, and S116 to the game specification of the first embodiment shown in FIG. In the gaming state, the background color of the effect symbol display device 2 is red, and in the gaming state where the winning probability of the lottery for winning is low, the background color of the effect symbol display device 2 is light blue, It actively notifies the player that the winning probability has been shifted from a high probability to a low probability. About others, since it is the same as the game specification of 1st Embodiment, description is abbreviate | omitted. The game specification of this example sets the probability of winning per win when the power is turned on, and also shifts the winning probability per win from the high probability to the low probability at the timing of winning the sudden probability change lottery. Similar to the game specifications of the embodiment, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. In addition, since the effect symbol display device 2 is notified of whether the gaming state is in a high probability state or a low probability state, the player must know the probability state of the lottery accompanying the winning of a game ball at the start port 3. Can do.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a flowchart showing the game specifications of the third embodiment, and FIG. 9 is a timing chart showing the timing at which the winning probability in the game specifications of the third embodiment shifts from a high probability to a low probability or from a low probability to a high probability. It is. The game specification of the third embodiment is based on the winning of a game ball at the start port 3, and a lottery of a, b, and e shown in FIG. It is characterized by shifting from a high probability to a low probability and not notifying the effect symbol display device 2 whether the gaming state is in a high probability state or a low probability state.

  When the RAM 120 is initialized when the power is turned on, the CPU 110 sets the probability of winning the winning combination to a high probability (step S201).

  Next, the process proceeds to step S203, where it is determined whether or not a game ball has been won at the start port 3, in other words, whether or not there is a special symbol winning hold, and if there is a special symbol winning hold. In step S204, it is determined whether or not the probability of winning the winning lottery is high. In the state where the RAM 120 is initialized when the power is turned on, the probability of winning the winning lottery in step S201 is set to a high probability, so the process proceeds to step S205 to execute the falling lottery. It is determined whether or not the lottery is won (step S206). If it is determined in step S203 that there is no special symbol winning suspension, the process waits until there is a game ball winning at the start port 3.

  If it is determined in step S206 that the lottery for falling has been won, the process proceeds to step S207, where the probability of winning the winning lottery is shifted to a low probability, and the winning lottery is performed with a low probability. (Step S208). Next, the process proceeds to step S209, where it is determined whether or not the jackpot 1 lottery has been won. If it is determined in step S209 that the jackpot 1 lottery has been won, the process proceeds to step S210. The probability of winning the lottery is shifted to a high probability, and the process returns to step S202. On the other hand, if it is determined in step S209 that the jackpot lottery has not been won, the probability of winning the winning lottery is maintained at a low probability, and the process returns to step S202.

  If it is determined in step S204 that the probability of winning the winning lottery is not high, the process proceeds to step S211, a winning lottery is performed with a low probability, and the process proceeds to step S209. If it is determined in step S206 that the falling lottery has not been won, the process proceeds to step S212, a winning lottery with a high probability is performed, and the process proceeds to step S209.

  Therefore, in the gaming specifications of the third embodiment, as shown in FIG. 9, the probability of winning the winning lottery is high when the power is turned on (when the RAM 120 is initialized), and in this state the fall When you win the lottery, or when you win the jackpot 2 lottery, the probability of winning the winning lottery shifts from high probability to low probability, and in the state that has shifted to low probability, to the jackpot 1 lottery Shifts from low probability to high probability when winning.

  The game specification of this example sets the probability of winning per win when power is turned on, and shifts the winning probability per win at the timing of winning the falling lottery from the high probability to the low probability. Similar to the game specifications of the form, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. In addition, when winning the falling lottery, the winning prize opening 4 is not opened / closed like when suddenly winning the winning lottery, so that the gaming state has a low probability due to the opening / closing operation of the winning prize opening 4. It can be prevented from being known to the player.

<Fourth embodiment>
A fourth embodiment of the present invention will be described with reference to FIG. FIG. 10 is a flowchart showing the game specifications of the fourth embodiment. The gaming specifications of the fourth embodiment are based on the winning of game balls at the start port 3 and the lottery of a, b, e shown in FIG. It is characterized by shifting from a high probability to a low probability and informing the effect symbol display device 2 whether the gaming state is in a high probability state or a low probability state.

  As shown in FIG. 10, in the game specification of the fourth embodiment, steps S202, S213, and S214 are added to the game specification of the third embodiment shown in FIG. In the state, the background color of the effect symbol display device 2 is red, and in the gaming state where the winning probability of the lottery for winning is low, the background color of the effect symbol display device 2 is light blue, so that the winning probability of the lottery regarding winning is determined. Is actively notified to the player that the game has been shifted from a high probability to a low probability. About others, since it is the same as the game specification of 3rd Embodiment, description is abbreviate | omitted. The game specification of this example sets the probability of winning per win when power is turned on, and shifts the winning probability per win at the timing of winning the falling lottery from the high probability to the low probability. As with the game specifications of the form, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced, and the game state is in the high probability state or the low probability state in the production symbol display device 2 Therefore, the player can grasp the probability state of the lottery accompanying the winning of the game ball to the start port 3.

<Fifth Embodiment>
A fifth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a flowchart showing the game specifications of the fifth embodiment, and FIG. 12 is a timing chart showing the timing at which the winning probability in the game specifications of the fifth embodiment shifts from a high probability to a low probability or from a low probability to a high probability. It is. The game specification of the fifth embodiment is based on the winning of a game ball at the start port 3 and a lottery of a, b, c, d shown in FIG. The probability is shifted from a high probability to a low probability, and the winning probability is shifted from a low probability to a high probability at the timing when the lottery is suddenly shortened. It is characterized by not reporting whether there is a low probability state.

  When the RAM 120 is initialized when the power is turned on, the CPU 110 sets the probability of winning the winning combination to a high probability (step S301).

  Next, the process proceeds to step S303, where it is determined whether or not a game ball has been won at the start port 3, in other words, whether or not there is a special symbol winning hold, and if there is a special symbol winning hold. The lottery with respect to the winning a, b, c, and d shown in FIG. 4 is executed with the probability set in the CPU 110 (step S304). If it is determined in step S303 that there is no special symbol winning suspension, the process waits until there is a game ball winning at the start port 3.

  After the lottery, it is determined whether or not a win is made (step S305). If it is determined that no win is made, that is, if it is determined that the game is “out”, the process proceeds to step S303. Return. If it is determined in step S305 that it has been won in any way, the process proceeds to step S306, where it is determined whether or not it has been suddenly won by chance, and if it is determined in step S306 that it has been suddenly won by chance, After moving to step S307 and executing the process in the case of winning the sudden probability change shown in FIG. 4, the probability of winning the win is shifted to a low probability (step S308). Thereafter, the process returns to step S303.

  If it is determined in step S306 that the lottery has suddenly changed, the process proceeds to step S309, and it is determined whether or not the jackpot 2 lottery is won. If it is determined in step S309 that the jackpot 2 lottery has been won, the process proceeds to step S310, and after performing the process of winning the jackpot 2 shown in FIG. The process proceeds (step S311).

  In step S309, when it is determined that the lottery is shifted to the jackpot 2 lottery, the process proceeds to step S313, and it is determined whether or not the lottery of a short time is won. If it is determined in step S313 that the lottery has not been won suddenly, the processing for winning the jackpot 1 shown in FIG. 4 is executed (step S314), and the probability of winning the win remains high. Maintain (step S315) and return to step S303. On the other hand, if it is determined in step S313 that the sudden lottery has been won, the processing for sudden win in FIG. 4 is executed (step S317), and then the process proceeds to step S315.

  Therefore, in the gaming specifications of the fifth embodiment, as shown in FIG. 12, the probability of winning the winning lottery is high at power-on (when the RAM 120 is initialized) and suddenly changes in this state. When winning the lottery, and when winning the jackpot 2 lottery, transition from high probability to low probability, when winning the lottery 1 lottery with the transition to low probability, and suddenly short When the lottery is won, it shifts from low probability to high probability.

  The game specification of this example sets the probability of winning per win when the power is turned on, and also shifts the winning probability per win from the high probability to the low probability at the timing of winning the sudden probability change lottery. Similar to the game specifications of the embodiment, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. In addition, when you win a lottery for a short time, the probability of winning a winning lottery shifts from a low probability to a high probability, so the probability of winning a winning lottery once shifted from a high probability to a low probability is again high. It is easy to shift to and can further enhance the interest of the player. Further, since it is not notified to the effect symbol display device 2 whether the gaming state is in the high probability state or the low probability state, the pachinko machine is not impressed strongly that the gaming state advantageous to the player has ended. It is possible to connect the player's interests to the pachinko machine and increase the operating rate of the pachinko machine. In particular, as illustrated in FIG. 4, the opening / closing pattern (number of rounds and opening time per round) of the big winning opening 4 when winning a lottery with sudden change in probability, and the big winning when winning a lottery with a short time. If the opening / closing pattern of the mouth 4 is made the same, it is possible to prevent the current gaming state from being determined from the opening / closing operation of the special winning opening 4, so that the effect of connecting the player's interest in the pachinko machine is further enhanced. be able to.

<Sixth Embodiment>
A sixth embodiment of the present invention will be described with reference to FIG. FIG. 13 is a flowchart showing the game specifications of the sixth embodiment. The game specification of the sixth embodiment is based on the winning of a game ball at the start port 3, and a lottery of a, b, c, and d shown in FIG. The probability is shifted from a high probability to a low probability, and the winning probability is shifted from a low probability to a high probability at the timing when the lottery is suddenly shortened. It is characterized by notifying whether there is a low probability state.

  As shown in FIG. 13, the game specifications of the sixth embodiment are obtained by adding steps S302, S312, S316 and S318 to the game specifications of the fifth embodiment shown in FIG. In the gaming state, the background color of the effect symbol display device 2 is red, and in the gaming state where the winning probability of the lottery for winning is low, the background color of the effect symbol display device 2 is light blue, It actively notifies the player that the winning probability has been shifted from a high probability to a low probability. About others, since it is the same as the game specification of 5th Embodiment, description is abbreviate | omitted. The game specification of this example sets the probability of winning per win when the power is turned on, and also shifts the winning probability per win from the high probability to the low probability at the timing of winning the sudden probability change lottery. Similar to the game specifications of the embodiment, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. In addition, when you win a lottery for a short time, the probability of winning a winning lottery shifts from a low probability to a high probability, so the probability of winning a winning lottery once shifted from a high probability to a low probability is again high. As with the game specifications of the fifth embodiment, the player's interest can be enhanced. Further, since the effect symbol display device 2 is notified of whether the gaming state is in a high probability state or a low probability state, the player can grasp the probability state of the lottery accompanying the winning of the game ball to the start port 3. Can do.

<Seventh embodiment>
A seventh embodiment of the present invention will be described with reference to FIG. FIG. 14 is a flowchart showing the game specifications of the seventh embodiment. The game specifications of the fourth embodiment are based on the winning of a game ball at the start port 3 and a lottery of a, b, c, and d shown in FIG. The probability is shifted from a high probability to a low probability, and the winning probability is shifted from a low probability to a high probability at the timing when the lottery is suddenly shortened. Until the first win, even if a lottery suddenly wins, the player will not be notified that the winning probability has changed from a high probability to a low probability, and the winner will be the first to win a lottery 1, 2 Then, the player is informed that the winning probability has been shifted from a high probability to a low probability by winning a lottery of probability variation.

  When the RAM 120 is initialized when the power is turned on, the CPU 110 sets the probability of winning a win to a high probability (step S401), and then increases the winning probability of 1 or 2 for the jackpot when a winning lottery is suddenly won. The notification flag 0 indicating that the player has not been notified of the transition from the probability to the low probability is set (step S402), and the probability of winning the background color of the effect symbol display device 2 is high. A color other than the color indicating the color (for example, red) and the color indicating that the probability of winning the win is low (for example, light blue) is set (step S403).

  Next, the process proceeds to step S404, where it is determined whether or not there is a game ball winning at the start port 3, in other words, whether or not there is a special symbol winning hold, and if there is a special symbol winning hold. The lottery for the winning shown in FIG. 4 is executed with the probability set in the CPU 110 (step S405). If it is determined in step S404 that there is no special symbol winning suspension, the process waits until there is a game ball winning at the start port 3.

  After the lottery, it is determined whether or not any winning is made (step S406). If it is determined that no winning is made, the process returns to step S404. If it is determined in step S406 that it has been won in some way, that is, if it is determined to be “out of place”, the process proceeds to step S407, where it is determined whether or not a sudden change has been won. If it is determined that the winning is won, the process proceeds to step S408, and after executing the process in the case of winning the sudden probability change shown in FIG. 4, the probability of winning the win is shifted to a low probability (step S409). Thereafter, the process proceeds to step S410, and a notification flag 1 indicating that the player is notified that the winning probability has been shifted from a high probability to a low probability when the set notification flag is suddenly won in a random lottery. It is determined whether or not. Since the notification flag 0 is set until the first winning lottery of 1 or 2 is won, it is determined No in step S410 and the process returns to step S404.

  If it is determined in step S407 that the lottery has suddenly changed, the process proceeds to step S412 to determine whether or not the lottery has been won suddenly. If it is determined in step S412 that the sudden lottery has been won, the process proceeds to step S413, and after performing the process of winning in the sudden time shown in FIG. It keeps (Step S414), and it shifts to Step S414A and it is judged whether an information flag is 1. At this stage, since the notification flag is set to 0 in step S402, it is determined No and the process returns to step S404.

  If it is determined in step S412 that the lottery has suddenly shifted, the process proceeds to step S416, the notification flag 1 is set, and then it is determined whether or not the jackpot 2 lottery is won (step S417). If it is determined in step S417 that the jackpot 2 lottery has been won, the process proceeds to step S418, and after performing the process of winning the jackpot 2 shown in FIG. The process proceeds (step S419). After that, the background color of the effect symbol display device 2 is changed to a color indicating that the probability of winning the win has shifted to a low probability, for example, light blue (step S420), and the process returns to step S404.

  In step S417, if it is determined that the lottery has been shifted to the jackpot 2 lottery, the process proceeds to step S421, and after performing the process of winning the jackpot 1 shown in FIG. It is maintained as it is (step S422). Thereafter, the background color of the effect symbol display device 2 is changed to a color indicating that the probability of winning in the win is high, for example, red (step S423), and the process returns to step S404.

  After determining that the notification flag 1 has been set in step S416, if it is determined in step S407 that a sudden change has been won, the processes in step S408, step S409, and step S410 are performed in sequence, and then the process proceeds to step S411. Then, the background color of the effect symbol display device 2 is changed to a color indicating that the probability of winning in the win is low, for example, light blue (step S411), and the process returns to step S404. Also, after the notification flag 1 is set in step S416, if it is determined in step S412 that the winning time is suddenly shortened, the processing in step S413, step S414, and step S414A is performed in sequence, and then the process proceeds to step S415. Then, the background color of the effect symbol display device 2 is changed to a color indicating that the probability of winning the jackpot 1 or 2 is high, for example, red, and the process returns to step S404.

  Therefore, also in the game specification of the seventh embodiment, as in the game specification of the fifth embodiment, the probability of winning the winning lottery is high when the power is turned on (when the RAM 120 is initialized). When you win a lottery with a sudden probability change and a jackpot 2 lottery in the state, when you win a lottery with a jackpot 1 lottery and sudden lottery with a transition to a low probability Transition from low probability to high probability (see FIG. 12).

  The game specification of this example sets the probability of winning per win when the power is turned on, and also shifts the winning probability per win from the high probability to the low probability at the timing of winning the sudden probability change lottery. Similar to the game specifications of the embodiment, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. In addition, when you win a lottery for a short time, the probability of winning the winning lottery shifts from a low probability to a high probability, so the probability of winning a winning lottery once transferred from a high probability to a low probability is once again high. As with the game specifications of the fifth embodiment, the player's interest can be enhanced. Furthermore, until the first win of the jackpot 1 or 2 lottery, even if the winning lottery suddenly wins, the player will not be notified that the winning probability has shifted from a high probability to a low probability. Until the first lottery is won, the player's interest is not significantly impaired, and the operating rate of the pachinko machine can be increased.

<Eighth Embodiment>
An eighth embodiment of the present invention will be described. The game specification of the eighth embodiment is based on the winning of a game ball at the start port 3, and a lottery of a, b, c, and d shown in FIG. Probability shifts from high probability to low probability, and at the timing when a lottery is suddenly won, the winning probability shifts from low probability to high probability, and even after winning the jackpot 1,2 lottery for the first time The winning probability shifts from a high probability to a low probability by winning a lottery sudden change, and the winning probability shifts from a low probability to a high probability by winning a lottery suddenly This is characterized by not informing the player of this. This game specification can be realized by omitting steps S402, S410, S414A, S411, S415, and S416 shown in FIG. About others, since it is the same as the game specification of 7th Embodiment, description is abbreviate | omitted. The game specification of this example sets the probability of winning in the case of power-on when the power is turned on at a high probability, and the winning probability per win at the timing of winning the sudden chance change lottery from low to high probability Therefore, similarly to the game specifications of the first embodiment, it is easy to prompt the player to visit the store, and the burden on the game store side can be reduced. In addition, when you win a lottery for a short time, the probability of winning the winning lottery shifts from a low probability to a high probability, so the probability of winning a winning lottery once transferred from a high probability to a low probability is once again high. As with the game specifications of the fifth and seventh embodiments, the player's interest can be enhanced. Furthermore, in the game specification of this example, when winning the lottery 1 lottery, it is displayed on the production symbol display device 2 that the winning probability is changed from low probability to high probability. When winning the lottery, the fact that the winning probability has been shifted from a high probability to a low probability is displayed on the production symbol display device 2, so that the player draws with the winning to the starting port 3 after the big hit Can be grasped.

<Ninth Embodiment>
A ninth embodiment of the present invention will be described with reference to FIG. FIG. 15 is a flowchart showing the game specifications of the ninth embodiment. The game specification of the ninth embodiment is based on the winning of a game ball at the start port 3 and a lottery of a, b, and c shown in FIG. It is characterized by shifting from a high probability to a low probability and informing the effect symbol display device 2 whether the gaming state is in a high probability state or a low probability state. As shown in FIG. 15, this game specification can be realized by omitting steps S412 to S415 described in FIG. About others, since it is the same as the game specification of 7th Embodiment, description is abbreviate | omitted. The game specification of this example sets the probability of winning per win when the power is turned on, and also shifts the winning probability per win from the high probability to the low probability at the timing of winning the sudden probability change lottery. Similar to the game specifications of the embodiment, it is easy to encourage the player to visit the store, and the burden on the game store side can be reduced. Further, since the effect symbol display device 2 is notified of whether the gaming state is in a high probability state or a low probability state, the player can play a game to the start port 3 as in the second embodiment and the fourth embodiment. The probability state of the lottery accompanying the winning of the ball can be grasped. Furthermore, the game specification of this example does not change the winning probability of the lottery associated with the winning of the game ball to the starting port 3 by using the sudden time reduction, so it can be applied to a pachinko machine that does not have a sudden time reduction game specification. become.

<Tenth embodiment>
A tenth embodiment of the present invention will be described with reference to FIG. FIG. 16 is a flowchart showing the game specifications of the tenth embodiment. The game specification of the tenth embodiment is based on the winning of a game ball at the start port 3, and a lottery of a and e shown in FIG. 4 is performed. In addition to the transition to a low probability, after the initialization of the RAM 120, until the first win of the jackpot 1 lottery, even if the winning lottery is won, the game that the winning probability has been shifted from a high probability to a low probability Notifying the player, after winning the first lottery lottery, by notifying the player that the winning probability has been shifted from high probability to low probability by winning the falling lottery Features.

  When the RAM 120 is initialized when the power is turned on, the CPU 110 sets the probability of winning a win to a high probability (step S501), and then the winning probability per win is reduced from a high probability to a low probability when a falling lottery is won. A notification flag 0 indicating that the player will not be notified of the transition is set (step S502), and the background color of the effect symbol display device 2 is a color indicating that the probability of winning the win is high (for example, (Red) and a color other than a color (for example, light blue) indicating that the winning probability is low (Step S503).

  Next, the process proceeds to step S504, where it is determined whether or not there is a game ball winning at the start port 3, in other words, whether or not there is a special symbol winning suspension, and if there is a special symbol winning suspension. Shifts to step S505 to determine whether or not the probability of winning the winning lottery is high. The probability of winning the winning lottery is set to a high probability until the first winning lottery is won. Therefore, the process proceeds to step S506, and the falling lottery is performed. If it is determined in step S504 that there is no special symbol winning suspension, the process waits until there is a winning game ball at the start port 3.

  After the falling lottery, the process proceeds to step S507 to determine whether or not the falling lottery is won. If it is determined in step S507 that the lottery for falling has been won, the process proceeds to step S508, and the player is notified that the winning probability has been shifted from a high probability to a low probability by winning the falling lottery. It is determined whether or not a notification flag 1 indicating notification is set. Since the notification flag 0 is set until the first jackpot lottery is won, the process proceeds to step S512 to determine whether or not the jackpot 1 lottery is won.

  If it is determined in step S512 that the jackpot 1 lottery has been won, the probability of winning the jackpot lottery is maintained at a high probability (step S513), and the jackpot 1 win is the first after initialization of the RAM 120. It is determined whether or not the winning is made (step S514). When it is determined in step S514 that the winning of the jackpot 1 is the first winning after the initialization of the RAM 120, the notification flag 1 is set (step S515), and the background color of the effect symbol display device 2 is determined. A color indicating that the probability of winning is a high probability, for example, red is maintained (step S516), and the process returns to step S504. If it is determined in step S512 that the lottery is a lottery, the process directly returns to step S504. Furthermore, when it is determined in step S514 that the winning of the jackpot is the second or subsequent winning after initialization of the RAM 120, the process returns to step S504 via step S516.

  After initialization of the RAM 120, after winning one or more lottery wins, the notification flag 1 is set in step S515. Therefore, in step S508, it is determined that the notification flag 1 is set, and step S509 is performed. Then, the background color of the effect symbol display device 2 is changed to a color indicating that the probability of winning in the win is low, for example, light blue (step S509). Next, the probability of winning the winning lottery is shifted to a low probability (step S510), the winning lottery is performed with a low probability (step S511), and the flow proceeds to step S513.

  In step S510, after the probability of winning the winning lottery is shifted to a low probability, it is determined in step S505 that the gaming state is not a high probability state, and the flow shifts to step S517 to reduce the winning lottery. Proceeding with probability, the process proceeds to step S512. If it is determined in step S507 that the lottery has been lost, the process proceeds to step S518, where the winning lottery is performed with high probability, and the process proceeds to step S512.

  Therefore, in the game specification of the tenth embodiment, as in the game specification of the third embodiment, the probability of winning the winning lottery is high when the power is turned on (when the RAM 120 is initialized). When the lottery of falling is won in the state, it shifts from high probability to low probability, and when it is transferred to low probability, it shifts from low probability to high probability when winning the jackpot 1 lottery (FIG. 9). reference).

  The game specifications of the present example can obtain the same effects as the game specifications according to the third embodiment until at least the first winning lottery is won.

  In addition, in the pachinko machine of the present invention, as illustrated in FIGS. 17 (a) and 17 (b), one of the jackpots 1, 2, the sudden probability change and the sudden time reduction lottery is won, and the winning process for each win After the game is completed, the game in the short-time mode can be given a predetermined number of times (100 times in the example of FIG. 17) as a privilege. In the short-time mode game, in the lottery performed with the passing of the game ball to the normal symbol actuating gate 7, the probability that the ordinary electric accessory 12 is opened is increased and the ordinary electric accessory 12 per time is increased. This is a game mode in which a lottery for winning can be performed a predetermined number of times (100 times) in a short time by making the opening time of the game longer than usual. Since a predetermined number of lotteries can be received in a short time, the consumption of game balls can be reduced, which is advantageous for the player.
