Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine and a simulation game program that display a special symbol in a variable manner upon a start winning and when a predetermined combination of symbols stops, a big hit is made to open a big winning port.
[0002]
[Prior art]
In a gaming machine represented by a pachinko gaming machine, when a game ball fired on the board of the gaming board wins the starting winning prize while flowing down the board, a random number for jackpot determination is extracted, and this random number value is It is stored in a predetermined area of the RAM.
[0003]
Then, the special symbol of the symbol display device is variably displayed based on the determination result, and the special symbol variable game is performed. In the jackpot determination, if the random number value stored in the RAM is a predetermined random number value, a jackpot win is obtained, and if the random number value is any other random value, the winning is lost.
[0004]
When a big hit is won, a big hit game is performed subsequent to the special symbol change game. In this big hit game, a big winning opening is opened, and the player can acquire a large amount of prize balls.
[0005]
Also, if there is a starting prize during the special symbol change game, a big hit determination random number is extracted according to the starting prize, and this random number value is sequentially stored as a predetermined number, for example, up to four as reserved balls. The number of the reserved balls is displayed by turning on the four reserved ball storage LEDs.
[0006]
When the special symbol variation game currently being performed is completed, the next new special symbol variation game is performed for the number of stored balls in accordance with the random number value stored in the RAM, and the game is executed by using the reserved balls. Continued until
[0007]
In such a conventional gaming machine, the number of reserved balls stored in the RAM is limited to a predetermined number of four, so that four reserved balls are stored and all the reserved ball storage LEDs are turned on. No matter how much the starting ball prize is generated, it is not stored as a reserved ball, and no big hit determination is performed based on it, so that a big hit does not occur.
[0008]
For this reason, the player stops the launch of the game balls when the reserve balls are accumulated to some extent, particularly when the reserve balls are up to the upper limit, and resumes the launch of the game balls after the reserve balls are consumed, so-called, Playing a game called "stopping".
[0009]
As described above, during the special symbol change game with the reserved balls accumulated, the player has no hand holding, and if such a hitting is rampant, the time during which the game ball is not fired increases. The actual operating rate of the gaming machine is reduced. Then, when the upper limit of the pending storage increases, this tendency further increases.
[0010]
As a solution to such a problem, it is known that when the reserved balls are accumulated (especially when the upper limit value is reached), the fluctuation time of the special symbol is reduced, and the digestion of the reserved balls is accelerated. (For example, see Patent Document 1).
[0011]
[Patent Document 1]
JP 2001-259158 A
[0012]
[Problems to be solved by the invention]
However, in such a conventional gaming machine, if the fluctuation time of the special symbol is excessively shortened while the reserved balls are accumulated, the number of times the special symbol changes per unit time increases. For this reason, the number of occurrences of the jackpot per hour (that is, the opportunity for the jackpot to occur) increases, resulting in a remarkable increase in gambling.
[0013]
In addition, it is possible to reduce the fluctuation time of the special symbol to the extent that the reserved ball does not collect. However, shortening the fluctuation time is not an effective means for preventing the stoppage.
[0014]
Therefore, the present invention can improve the playability of the player by preventing the hitting and preventing a substantial decrease in the operation rate, and can provide a profit to the game store. It is an object of the present invention to provide a gaming machine and a simulation game program that can be provided.
[0015]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a gaming machine of the present invention is provided in a gaming area of a gaming board provided with a symbol variation displaying means capable of varyingly displaying a symbol related to a game, an effect displaying means for displaying an effect image, and a game ball. A winning prize ball detecting means for detecting that a prize has been won, and when the starting prize ball detecting means detects a game ball during the fluctuation display of the symbol, the fact that the game ball has been detected is stored as a reserved ball. The present invention is characterized in that it comprises a retaining ball storage means, and changing means for changing a probability of displaying a unique effect image on the effect display means in accordance with the number of retaining balls stored in the retaining ball storage means.
[0016]
In this case, when it is determined that the number of reserved balls stored in the reserved ball storage means is, for example, 10 and the jackpot game state is reached, the number of reserved balls stored in the reserved ball storage means has reached 10. Since the special effect image different from the effect image in the big hit game state when there is no special effect image is displayed on the effect display means at a predetermined probability, for example, a probability of 50%, the special effect-added game state is set. In order to obtain a bonus-added gaming state in which an image can be viewed, a game in which a game ball is continuously fired so as to win a start winning opening is performed.
[0017]
For this reason, it is possible to prevent hitting and reduce the time during which the game ball is not fired, thereby preventing a substantial decrease in the operating rate of the gaming machine. As a result, the player does not become out of hand, can improve the playability of the player, and can give a profit to the game store.
[0018]
Further, in the game state with the privilege, the probability that the effect display means displays a unique image is higher as the number of the reserved balls stored in the reserved ball storage means is higher. In order to increase the number of game balls, the game balls will be continuously fired so as to win the starting winning opening, which can further prevent the hitting, and the game ball can be shot with less time when the game ball is not fired. It is possible to further prevent the actual operation rate of the machine from decreasing.
[0019]
In the gaming machine of the present invention, in order to solve the above-described problem, when the number of reserved balls stored in the reserved ball storage unit has reached a predetermined number, the changing unit displays the effect display unit. The unique image is always displayed.
[0020]
In this case, when the number of reserved balls stored in the reserved ball storage means has reached a predetermined number, for example, 20 pieces, a unique image is always displayed on the effect display means. In order to increase the number of held balls, the game balls are continuously fired so as to win the starting winning opening, so that the hitting can be further prevented, and the time during which the game balls are not fired can be further reduced. It is possible to further prevent a substantial decrease in the operating rate of the gaming machine by reducing the number.
[0021]
In order to solve the above-mentioned problems, a simulation game program of the present invention provides a computer with a symbol variation display function capable of varyingly displaying symbols related to a game, an effect display function of displaying an effect image, and a game area of a game board. The starting winning ball detection function for detecting that the game ball has won, and the starting winning ball detection function detects the game ball during the fluctuation display of the symbol, the game ball is detected And a change function of changing a probability of displaying an effect image unique to the effect display function according to the number of the hold balls stored in the hold ball storage function. It is characterized by:
[0022]
In this case, each of the simulation programs described above is stored in a storage medium such as a ROM cartridge, CD-ROM, or DVD, or distributed under a network environment such as a communication satellite or using a communication line such as the Internet. By doing so, similarly to a gaming machine in a home-use game machine or the like, an effect image when the number of reserved balls stored by the storage function has reached, for example, 10 and the number of reserved balls has not reached 10 Since the unique effect image different from the original image is displayed with a predetermined probability, for example, a probability of 50%, the player can start the game ball in order to obtain a special game state in which the special image can be viewed. A game that continues to be fired as detected by the ball detection function is performed.
[0023]
As a result, the hitting can be prevented, and the time during which the game ball is not fired can be reduced, so that the substantial operation rate of the game machine can be prevented from lowering. As a result, the player is not left out of hand, can improve the playability of the player, and can give a profit to the game store.

The big hit determination random number is acquired at the timing when the game ball wins the starting winning opening 14.
[0077]
In FIG. 6 (a), for example, when 14 game balls have won the starting winning opening 14 while the symbol is being changed (the changing random number value 58 for the jackpot during the change), 128 are stored in the storage position 1 of the reserved ball storage area 33a. , A big hit determination random value of 248 at storage location 2, a big hit determination random value of 2 at storage location 3, a big hit determination random value of 207 at storage location 8, and 14 stores a random number for jackpot determination of 139.
[0078]
Also, when the reserved balls are stored in the storage positions 1 to N (N is 2 or more and 20 or less), the reserved balls stored in the reserved ball storage area 33a are displayed in the special symbol storage display sections 21a and 21b. It is supposed to be. In FIG. 5, since 14 reserved balls are stored in the reserved ball storage area 33a, "1" is displayed on the right special symbol storage display section 21a, and "4" is displayed on the left special symbol storage display section 21b. , There are 14 reserved balls.
[0079]
Then, when the special symbol change game currently being performed is completed, as shown in FIG. 6B (the storage position 6 or more is omitted in FIG. 6B), the random number value for the big hit determination during the change is deleted. The random number for big hit determination is moved from the storage position 1 to the changing position, from the storage position 2 to the storage position 1, from the storage position 3 to the storage position 2, and displayed on the special symbol storage display sections 21a, 21a. This operation is continued until the reserved balls are digested. Then, if the changing random number for big hit determination matches the random number for big hit determination in the big hit determination table stored in the main ROM 32, a big hit is determined.
[0080]
In the present embodiment, the number of reserved balls stored in the main RAM 33 is limited to 20, and when 20 reserved balls are stored and “20” is displayed on the special symbol storage and display sections 21a and 21a. However, no matter how much the starting ball wins thereafter, it is not stored as a reserved ball, and no big hit determination is made based on the stored ball.
[0081]
In the present embodiment, the main CPU 31 checks the reserved balls stored in the reserved ball storage area 33a of the main RAM 33 for each game, and determines that a predetermined number of game balls (for example, 10 pieces) are stored in the reserved ball storage area 33a. ), The number of the reserved balls stored in the reserved ball storage area 33a does not reach the predetermined number, and a unique effect image which will not appear in the effect image in the normal game state or the big hit game is described below. 13, a "game state with privilege" to be displayed.
[0082]
In the present embodiment, the main CPU 31 constitutes a changing unit.
[0083]
Next, a procedure of a control process performed in the main board 30 will be described based on the flowcharts of FIGS. 7 to 13 show the case where the main CPU 31 performs processing based on the control program stored in the main ROM 32.
[0084]
First, on the main board 30, when the power is turned on by the main CPU 31, a "main game process" as shown in FIG. 7 and an "interrupt process" as shown in FIG. 8 are executed.
[0085]
In the main game process at the time of power-on shown in FIG. 7, first, a startup process at the time of resetting of the main CPU 31 is performed to initialize the main CPU 31 (step S1), and then an "interrupt permission flag" is set. As a result, "interrupt processing" shown in FIG. 8 is executed (step S2).
[0086]
Next, after performing "error notification processing" (step S3), "special symbol change control processing" described later is executed (step S4). The “special symbol change control process” will be described later with reference to FIG. A plurality of flags including the above-mentioned interrupt permission flag are stored in the main RAM 33. Setting a flag means rewriting the value of the flag from "0" to "1".
[0087]
FIG. 8 is a flowchart showing the "interrupt processing". The main CPU 31 periodically (for example, every 3 ms) on condition that the "interrupt permission flag" is set in step S2 (FIG. 7) or step S21 described later. Is executed.
[0088]
In this "interrupt processing", the main CPU 31 first saves each register in the main RAM 33 (step S11). Subsequently, the random number value of the random number counter is updated (step S12). The random number counters for which the random number value is updated in the process of step S12 are “big hit determination random number counter”, “reach determination random number counter”, “symbol determination random number counter”, and “variation pattern selection random number counter”. In the process of step S12, the main CPU 31 rewrites the random number value of each random number counter to a value obtained by adding “1”.
[0089]
These various random number counters have a predetermined updatable numerical range, and when reaching the upper limit of the numerical range, the main CPU 31 resets the counter value of the random number counter to “0”.
[0090]
Specifically, in step S12, the updating process of the big hit determination counter 71, the big hit symbol determination counter 73, the off symbol determination counter 72, the reach determination counter 74, and the effect determination counter 75 is performed.
[0091]
As described above, the big hit determination counter 71 determines, for example, between 0 and 311 for determining whether or not the fluctuation result of the special symbol on the liquid crystal display device 13 is a “big hit” (big hit determination). The counter value is updated.
[0092]
The counter value of the big hit symbol determination counter 73 is updated, for example, in a range of 0 to 11 in order to select a stop mode at the big hit (selection of which special symbol to align).
[0093]
The outlier symbol determination counter 72 updates the counter value, for example, in the range of 0 to 11 for each of the left, middle, and right for selection of a stop mode in the outlier (selection of which special symbol to align). .
[0094]
The reach determination counter 74 is updated, for example, in the range of 0 to 9 in order to determine the presence or absence of the reach. The effect determination counter 75 is updated with a counter value in the range of, for example, 0 to 1023 for selection of an effect group of a miss effect, a reach effect, and a hit effect.
[0095]
After the update processing of these counters 71 to 75, the main CPU 31 sets a timer for measuring the opening time of the door of the special winning opening 17 performed when a big hit occurs, the display time of the special game displayed on the display screen 13a, and the like. Is performed (step S13), then "input port processing" for reading a signal input to the main CPU 31 is performed (step S14), and subsequently, "input signal processing" is executed (step S15).
[0096]
In the “input signal processing” of step S15, input of detection signals output from various sensors such as the starting ball sensor 51, the general winning ball sensor 52, the big winning ball sensor 53, the passing ball sensor 54, and the V winning ball sensor 55 is performed. Is checked, and processing according to these detection signals is performed. A specific processing procedure of the “input signal processing” will be described later with reference to FIG.
[0097]
Next, the main CPU 31 performs "ordinary symbol processing" (step S16). This "ordinary symbol processing" checks the presence / absence of the number of passed memories stored in the main RAM 33. If the number of passed memories is stored, reads out the random number for ordinary symbol determination from the main RAM 33, The normal random number value is compared with the random number value stored in the "normal symbol determination table", and it is determined whether or not the normal symbol display LEDs 11a and 11b are in a state where the left-side normal symbol display LED 21a, which is advantageous to the player, is turned on. I do. Then, the lighting operation of the ordinary symbol display LEDs 21a and 21b is controlled based on the determination result.
[0098]
Next, after executing the “payout process” (step S17), the main CPU 31 executes an error process (step S18). In the “payout process” of step S17, the main CPU 31 determines whether or not a payout request flag is set in the main RAM 33. When the flag is set, a control signal corresponding to the payout request flag is sent from the main CPU 31. The ball is transmitted to the prize ball control board 64, and the payout device 83 pays out game balls as prize balls.
[0099]
In “error processing” of step S18, an abnormality management processing for processing error signals generated from various devices is executed.
[0100]
Next, the main CPU 31 performs a transmission data output process of transmitting various commands stored in the main RAM 33 of the main board 30 to the symbol control board 61, the LED control board 62, the voice control board 63, and the prize ball control board 64. After performing (step S19), after restoring the data of each register saved in the predetermined area of the main RAM 33 of the main board 30 in step S11 (step S20), the "interrupt permission flag" is finally set. (Step S21), the “interrupt processing” ends.
[0101]
FIG. 9 shows the procedure of “input signal processing” in step S15. First, the main CPU 31 performs a “gate passage process” (step S31). In this process, the main CPU 31 determines whether or not the game ball has passed the normal symbol operation gate 15, that is, whether or not a detection signal has been input from the passing ball sensor 54. Here, when there is an input of a detection signal from the passing ball sensor 54, the main CPU 31 adds “1” to the passing storage number stored in a predetermined area of the main RAM 33.
[0102]
Next, after executing a “starting opening winning process” shown in FIG. 10 described later (step S32), a “winning opening winning process” is executed (step S33). In the "large winning opening winning process", a "payout request flag" for requesting the payout of a predetermined number (for example, 13) of winning balls according to the winning in the special winning opening 17 is set.
[0103]
Next, the main CPU 31 performs a "general winning opening winning process" (step S34). In this processing, the main CPU 31 checks the presence or absence of the input of the detection signal from the general winning sphere sensor 52, and if there is an input, a predetermined number (for example, five) according to the winning in the general winning lots 26a to 26d. "Payment request flag" for requesting the prize ball payout is set.
[0104]
Next, with reference to FIG. 10, a description will be given of the procedure of the “starting port winning process” of step S32 in FIG.
[0105]
10, first, the main CPU 31 determines whether or not a game ball has won the start winning port 14 based on a detection signal from the start winning ball sensor 51 (step S41). Is determined to have won, the payout request command is stored in the main RAM 33 (step S42).
[0106]
Next, it is determined whether or not the number of reserved balls stored in the reserved ball storage area 33a of the main RAM 33 has reached the upper limit value of 20 (step S43). If the number of retained balls has not reached the upper limit value, the random number for jackpot determination and the random number for jackpot symbol extraction extracted when the game ball has won the starting winning port 14 are stored in the reserved ball of the main RAM 33. It is stored in the area 33a (step 44), and the start-up winning process is ended. On the other hand, if it is determined in step 43 that the number of retained balls has reached the upper limit value, the processing in step 44 is not performed and the start-port winning process is terminated.
[0107]
Next, the procedure of the "special symbol control process" of step S4 (FIG. 7) will be described with reference to FIG.
[0108]
First, the main CPU 31 determines whether or not there is a start memory, that is, whether or not the number of start memories stored in the main RAM 33 is one or more (step S61). If the determination is "YES", the process shifts to step S63. If the determination is "NO", a "demo control process" is performed (step S62).
[0109]
Specifically, the main CPU 31 stores a “demo display command”, which is a control command for displaying a demonstration screen, in the main RAM 33. The “demo screen” is a screen that displays a demonstration such as a model name of a gaming machine. No special symbols are displayed on this screen.
[0110]
In the step S63, it is determined whether or not the random number for judging a big hit among the read random numbers is a hit value. If the hit value is a hit value ("YES" in the step S63), the process proceeds to the step S67. ("NO" in step S63), the process proceeds to step S64.
[0111]
If the result of the determination in step S63 is "big hit", the counter value of the big hit symbol determination counter 73 stored in the reserved ball storage area 33a of the main RAM 33 at the time of starting winning is read out as a random number for selecting a big hit stop mode.
[0112]
Then, with reference to the big hit symbol determination table stored in the main ROM 32, one of a plurality of predetermined big hit stop modes is selected to determine a big hit symbol (step S67). The big hit symbol determined here is a stop mode determined after stopping the fluctuation of the special symbol.
[0113]
Next, an effect selection table setting process, which will be described in detail with reference to FIG. 13, is executed, and a table corresponding to the number of stored balls is set from the effect selection tables stored in the main ROM 32 (step S68), and an interrupt is generated. The counter value of the effect determination counter 75 updated in step S12 of the process is read out as “the random number for the effect of stopping the big hit”, and a table corresponding to the stored number of the reserved balls set in step S68 is referred to in advance. One of the determined plurality of hit effects is selected to determine the hit effect (step S69).
[0114]
If the determination in step S63 is "miss", the counter value of the big hit symbol determination counter 73 stored in the reserved ball storage area 33a of the main RAM 33 at the time of the start winning is read as a random number for selection of the off stop mode.
[0115]
Then, with reference to a lost symbol determination table stored in the main ROM 32, one of a plurality of predetermined slippage stop modes is selected to determine a lost symbol (step S64). The off symbol determined here is a stop mode determined after stopping the change of the special symbol.
[0116]
Next, an effect selection table setting process which will be described in detail with reference to FIG. 13 is executed, and a table corresponding to the number of stored balls is set from the effect selection tables stored in the main ROM 32 (step S65), and an interrupt is generated. The counter value of the effect determination counter 75 updated in step S12 of the process is read out as “rendering random number in a departure stop mode”, and a table corresponding to the number of stored spheres set in step S65 is read in advance. One out of a plurality of determined effects is selected to determine a departure effect (step S66).
[0117]
When the special symbol stop mode and the effect mode are determined in steps S64, S65, S66, S67, S68, and S69, the special symbol variation control of the liquid crystal display device 13 is performed in accordance with the determined content. As shown, a "variation command" as a control command for the symbol control board 61 is generated and stored in the main RAM 33 (step S70).
[0118]
Then, the fluctuation command stored in the main RAM 33 is transmitted to the symbol control board 61 in the transmission data output processing (step S19 in FIG. 8) of the above-described interrupt processing.
[0119]
These "variation commands" are stored in the main RAM 33, and a symbol variation time waiting process is executed until a predetermined symbol variation time elapses (step S71). When the symbol stops, a "confirmation command" is generated and stored in the main RAM 33 (step S72).
[0120]
Next, it is determined whether or not a big hit has occurred (step S73). If the result of the determination is "out"("NO" in step S73), the "special symbol variation process end process" is executed to execute the special symbol variation process. Is ended (step S75).
[0121]
At this time, the changed random number value for jackpot determination, which has been changed, is deleted from the reserved ball storage area 33a, and the random number value for jackpot determination at each storage location is moved to another storage location. If the result of the determination in step S73 is "big hit"("YES" in step S73), after opening the special winning opening 17 and executing a "big hit game process" in FIG. 12 described later (step S74). Then, the "special symbol variation process end process" is executed (step S75), and the special symbol variation process is terminated.
[0122]
Next, the "big hit game process" executed in step S74 of FIG. 11 will be described with reference to FIG.
[0123]
First, the main CPU 31 reads a sound control command requesting the output of a big hit notification sound (fan fare sound) from the sound output device 82 from the main RAM 33 and transmits it to the sound control board 63, and outputs a big hit notification sound from the speakers 9L and 9R. (Step S81).
[0124]
Next, the main CPU 31 executes a round number display process of generating a round number display command and storing it in the main RAM 33 (step S82). Next, the CPU 31 outputs a special winning opening signal to the special winning device 66 to open the special winning opening 17 (step S83), and then sets the special winning opening 17 to the holding ball in steps S46, S50 and S52 of FIG. It is determined whether or not the upper limit number of game balls in one round set accordingly has won (step S84), and the routine goes to step S85.
[0125]
Here, if the upper limit of one round does not win ("NO" in step S84), it is determined whether 30 seconds have elapsed since the opening of the special winning opening (step S88), and if 30 has not elapsed. Then, the process proceeds to step S84, and if 30 seconds have elapsed, the process proceeds to step S85.
[0126]
In step S85, after a special winning opening closing signal is output to the special winning device 66 to close the special winning opening 17 (step S85), the special winning opening 17 is opened based on the detection signal from the V winning ball sensor 55. It is determined whether or not the game ball has won the V zone (step S86). If the game ball has won the V zone, it is determined whether or not the upper limit round (15 rounds in the present embodiment) has been reached. (Step S87) If the upper limit round has not been reached, the process returns to step S82 to execute the jackpot game of the next round, and if the upper limit round has been reached, the "big hit game process" ends.
[0127]
Next, the effect selection table setting process of steps S65 and S68 (FIG. 11) will be described with reference to FIG.
[0128]
First, the main CPU 31 determines whether the number of stored balls stored in the main RAM 33 is 10 or more (step S91). If this determination is "NO", the process moves to step S92, where the effect selection table stored in the main ROM 32 is set to Table 1 shown in FIG. 14A, and the effect selection table setting process ends.
[0129]
If the determination in step S91 is "YES", the flow proceeds to step S93, in which it is determined whether the number of reserved balls stored in the main RAM 33 has reached the upper limit value of 20. If the determination in step S93 is "NO", that is, if the number of stored balls is not less than 10 and less than 20, the flow proceeds to step S94, and the effect selection table is set in Table 2 shown in FIG. To end.
[0130]
If the determination in step S93 is “YES”, that is, if the number of stored balls has reached the upper limit (20 in the present embodiment), the process proceeds to step S95, and the effect selection table is changed to table 3 shown in FIG. And the effect selection table setting process ends.
[0131]
Specifically, for example, if the determination in step S63 (FIG. 11) is “YES”, that is, if the number of stored balls is 8 in the big hit determination, the process proceeds to step S68 (FIG. 11) as shown in FIG. Table 1 shown in FIG. 14 is set, and corresponds to the counter value of the effect determination counter 75 read out from the hit effect table on the right side of FIG. Decide what to do. In this case, as the effect, from the effect images shown in FIGS. 15 (a), (b), (c) and (d), the normal reach image of FIG. 15 (a) and the long reach image of FIG. 15 (b) , One of the super reach images of FIG. 15 (c) is determined. As can be seen by comparing the tables of FIGS. 14 (a), (b), and (c), the premium reach image shown in FIG. Is not selected when the table 2 is set, and is selected with a probability of 50% when the table 2 is set and 100% when the table 3 is set.
[0132]
If the number of stored balls is, for example, 15, the table 2 shown in FIG. 14B is set in step S68 (FIG. 11), and in step S69, the normal reach image shown in FIG. One of the premium reach images in d) is selected. Furthermore, when the number of stored balls is equal to or greater than 20, for example, 20, the premium reach image is always selected.
[0133]
The case where the determination in step S63 (FIG. 11) is “YES”, that is, the case of the big hit determination has been described above. The same applies when the determination in step S63 (FIG. 11) is “NO”, and FIG. ), (B), and (c), the left-side staging table is referred to, and the staging images at this time are shown in FIGS. 15 (a), (b), (c), and (d). Are displayed. The effect images shown in FIGS. 15A, 15B, 15C, and 15D may be inverted and displayed as unique images, that is, premium images.
[0134]
As described above, in the present embodiment, when the number of reserved balls stored in the main RAM 33 has not reached 10 while the number of reserved balls stored in the main RAM 33 has reached the predetermined number of 10 by the main CPU 31. Since the gaming state with the privilege of displaying the unique rendering image different from the rendering image on the liquid crystal display device 13 with a predetermined probability is set, the player plays the game ball to acquire the “gaming state with the privilege”. A game that continues to be fired so as to win the starting winning opening 14 is performed. As a result, the hitting can be prevented, and the time during which the game ball is not fired can be reduced, so that the substantial operation rate of the game machine can be prevented from lowering. As a result, the player does not become out of hand, can improve the playability of the player, and can give a profit to the game store.
[0135]
In the present embodiment, the storage upper limit value of the reserved sphere storage area 33a of the main RAM 33 is set to "20", but this upper limit value may be set arbitrarily. In the present embodiment, an image as shown in FIG. 15D is displayed as a unique image. For example, usually, a two-dimensional effect image is displayed, and a three-dimensional image is unique. May be set to be displayed as a simple image. Further, the effect image may be set so that the number of colors of the effect image is normally displayed in 256 colors, and a delicate full-color image having an extremely large number of colors is displayed as a unique image. Further, a character image popular with the player may be displayed as a unique effect image.
[0136]
Further, in the present embodiment, the probability of displaying a unique image is increased according to the number of reserved balls when the game mode is set to the “game state with privilege”. In order to obtain the "state", the game ball is continuously fired so as to win the starting winning opening 14, so that the hitting can be further prevented, and the time during which the game ball is not fired can be further reduced and the game can be performed. It is possible to further prevent the actual operation rate of the machine from decreasing.
[0137]
Further, in the present embodiment, a unique image is always displayed when the game state is set to the “game state with privilege”, so that the player starts the game ball to acquire the “game state with privilege”. Since the firing is continued so as to win the winning opening 14, the hitting can be further prevented, and the time during which the game ball is not fired is further reduced, and the actual operating rate of the gaming machine is reduced. Can be further prevented.
[0138]
FIG. 16 shows a simulation game program having the same game specifications as the pachinko gaming machine described above, which is stored in a recording medium such as a ROM cartridge, CD-ROM, DVD, or the like, in a network environment such as a communication satellite, or in the Internet or the like. It is distributed using a communication line.
[0139]
In FIG. 16, the present simulation game program is provided on a computer in a symbol variation display function 100 capable of varyingly displaying symbols relating to a game, an effect display function 101 for displaying an effect image, and a game ball provided in a game area of a game board. When the start winning ball detection function 104 detects a game ball during the fluctuation display of the symbol, the detection of the game ball is stored as a holding ball. This implements a reserved ball storage function 102 and a change function 103 that changes the probability of displaying a unique effect image on the effect display function 101 according to the number of reserved balls stored in the reserved ball storage function 102.
[0140]
A computer 114 such as a video game or a personal computer executes the functions 100 to 104, and a game board including a liquid crystal display device 13, a start winning port 14, a winning port 17 and the like on an image monitor 115 of the computer 114. In addition to projecting the entire image of No. 2, a pseudo game can be enjoyed while operating an operation switch 116 composed of a specific key, a dedicated operation button, and the like on a keyboard that changes to a lever of the firing handle 7.
[0141]
As a result, in a state where the number of reserved balls stored in the reserved ball storage function 102 has reached 10 in a home game machine or the like, similarly to the gaming machine, the effect image when the number of reserved balls has not reached 10 is Sets a “game state with privilege” in which different unique effect images are displayed on the effect display function 101 with a predetermined probability, so that the player places the game ball in the starting winning opening to obtain the “game state with privilege”. It will continue to fire like a prize. As a result, the hitting can be prevented, and the time during which the game ball is not fired can be reduced, so that the substantial operation rate of the game machine can be prevented from lowering. As a result, the player does not become out of hand, can improve the playability of the player, and can give a profit to the game store.
