JP 2008-237434 A

By the way, in the conventional pachinko machine, the success / failure determination process is executed by a program process of the main control device that controls the pachinko game, and whether or not the random number for the determination of success / failure and a plurality of determination values in the determination table of the success / failure match each other. Judging. The success / failure determination table includes a table for low probability and a table for high probability, and more determination values are set for high probability than for low probability.
However, in the conventional success / failure determination process, since the random number and the determination value are compared one by one, the program processing executed by the main control device requires a lot of processing time, which increases the processing load on the main control device and increases the processing speed. Is not enough. In particular, the tendency is large at the time of high probability compared with many judgment values. Moreover, there is a problem that the storage capacity of the main control device is increased by storing each determination value one by one and setting the low-probability and high-probability settings as the success / failure determination table. Judgments are not processed efficiently.

  Therefore, the present invention provides a ball game that can reduce the burden of program processing of the control device, improve the processing speed, efficiently process the determination of success / failure with probability fluctuation, and reduce the storage capacity of the control device. It was made as an issue to do.

According to the present invention, when a game ball enters a predetermined start opening of the game board, a random number for determination of success / failure is extracted, and whether or not the random number matches a predetermined determination value of the determination table for success / failure In the ball game machine that performs the judgment process and moves to a special game that is advantageous to the player if it matches,
A plurality of the determination values are set in the determination table, and the determination table is divided into a plurality of stages including the plurality of determination values.
Determines the success / failure determination means for executing the success / failure determination process for each stage of the success / failure determination table, loop control means for performing loop control so as to execute the success / failure determination process over a plurality of the stages, and the number of loops of the failure determination process. Loop number determining means,
The loop number determination means determines the loop number based on whether or not a predetermined condition set in advance in the game progress is satisfied, and the loop control means determines whether or not the loop is successful based on the determined loop number. The success / failure determination processing is performed at a plurality of stages of the table, and the winning probability of shifting to the special game is changed according to the game progress status (claim 1).

  Dividing the success / failure determination table step by step, and changing the number of loops of the failure determination processing executed over multiple stages of the success / failure determination table according to the game progress condition, so for the determination of success / failure when the number of loops is small With a small number of decision values compared with random numbers, it can be judged with low probability, and when the number of loops is large, it can be judged with high probability with many decision values compared with random numbers, thus efficiently processing the decision with probability variation can do. In addition, since the number of executions of the loop is changed in accordance with the establishment of the predetermined condition, it is possible to share the program for determining whether or not the condition is satisfied regardless of whether the condition is satisfied or not. Memory capacity can be reduced.

Each stage of the success / failure determination table is composed of a predetermined range consisting of a plurality of continuous determination values,
The success / failure determination unit compares the random number for determination of success / failure with the upper limit value and the lower limit value of the determination value of each step for each stage of the determination table, and determines whether the random number is within the range. Whether or not is determined (claim 2).

  The success / failure determination process can determine whether or not the random number is within the range of each stage by comparing the random number for determination of success / failure with the upper limit value and the lower limit value of each stage. Increase speed. Further, the success / failure determination table only needs to store the lower limit value and the upper limit value for each stage, and the storage capacity can be reduced.

The loop control means performs the success / failure determination process from a stage having a small determination value in the success / failure determination table to a stage having a large determination value, or from a stage having a large determination value to a stage having a small determination value. There is no loop control in order,
The success / failure determination unit compares the random number for determination of success / failure with the minimum value or the maximum value of the determination value of the determination result determination table in the initial stage of the determination of the success / failure, and the random number is smaller than the minimum value or When it is determined that the value is larger than the maximum value, the success / failure determination process is immediately terminated. (Claim 3).

  Since it is possible to determine a miss at the beginning of the determination process, the process can be terminated regardless of the number of loops, and the processing speed can be improved.

When the special symbol at the time of transition to the special game is a predetermined symbol set in advance, it has a probability variation function for changing the hit probability to a low probability or a high probability,
The loop number determination means determines the number of loops according to the variation state of the hit probability as the predetermined condition.

The game board is provided with a first start port and a second start port, and the game board has a special symbol display device based on the first random number for determination of success / failure extracted by entering the first start port. The first special symbol to be displayed is confirmed, and the second special symbol to be displayed on the special symbol display device based on the second random number for determination of success / failure extracted by entering the second starting port is Confirmed,
The loop number determination means determines the number of loops depending on which of the first or second special symbol is selected as the predetermined condition.

  Any of the configurations described in claims 4 and 5 is suitable as a condition for determining the number of loops, and can enrich the interest of the game.

The effect symbol control device 36 controls the display of the LCD panel in accordance with the command sent from the sub integration device 35.

Next, the operation of the pachinko machine 50 will be described.
First, an outline of “main processing” executed by the main controller 30 (strictly, its CPU) will be described with reference to FIG. The “main process” is composed of the main process (S10 to S80) and the remaining process (S90, S100), and is started due to an interrupt signal having a period of 2 ms. First, it is determined whether the interrupt is a normal interrupt (S10). . This determination is made based on whether or not a specific numerical value is written at a specific address in the RAM. If the determination is negative (NO), the initial setting (S11) is executed. The numerical value for determining whether or not it is a normal interrupt is written in the RAM as part of this initial setting.

  If it is a normal interrupt (S10: YES), an initial random number update process (S20), a random number update process for success / failure determination (S30), and a special symbol for determining the winning symbol used for displaying the result of the determination (win / fail) Symbol random number update process (S40), normal symbol random number update process (S50), each input process (S60), success / failure determination process (S70), each output process (S80) are performed, and then an interrupt signal is input. Within the remaining time until, the outlier symbol random number update processing (S90) and the initial random number update processing (S100) for determining the off symbol to be used for displaying the result of the success / failure determination (indication of loss) are loop-processed.

  Hereinafter, a part of subroutine processing of each input process (S60) and each output process (S80) will be described with a focus on the determination process (S70) deeply related to the present invention in the process executed by the main controller 30. .

In the success / failure determination process, the first or second random number for the determination of success / failure extracted due to the entry of the first or second start port 22A, 22B, and a predetermined determination value of the determination table It is determined whether or not they match. Prior to the description of the subroutine processing, the first and second random numbers used in this embodiment and the success / failure determination table will be described.
The first and second random numbers are extracted from 4000 numbers from 0 to 3999.
On the other hand, as shown in FIG. 9, the inside / outside determination table is divided into four stages, and each stage is set with a lower limit value and an upper limit value, and a range of a plurality of judgment values continuous between them. It consists of For example, in the first stage, a range consisting of five judgment values from 773 (0305H) to 777 (0309H), and in the second stage, a range consisting of five judgment values from 1773 (06EDH) to 1777 (06F1H), The third stage consists of 45 judgment values ranging from 2733 (0AADH) to 2777 (0AD9H), and the fourth stage consists of 45 judgment values ranging from 3733 (0E95H) to 3777 (0EC1H). Yes.

  Then, the success / failure determination table includes, for each stage, the lower digit of the upper limit value of the determination value, the upper digit of the upper limit value of the determination value, the lower digit of the lower limit value of the determination value, and the upper digit of the lower limit value of the determination value in hexadecimal numbers. As data, it is stored at the position indicated by the reference address of the memory for the success / failure determination table of the main controller 30.

  “Pending storage process 1” shown in FIG. 5 is a subroutine of each input process (S60), and it is confirmed whether there is a ball entering the start port 1 (S200). It is confirmed whether the number of holds in the hold memory is not the maximum value (S201). If the number of reservations is not the maximum value (yes), various random numbers including a first random number, such as a probable random number, a jackpot symbol determination random number, a reach symbol determination random number, a loss symbol determination random number, and a transition determination random number are extracted (S202). .

Next, prefetch determination is performed based on the first random number. (S203), “prefetch determination” is a provisional determination of whether or not to execute a hit announcement as an effect display mode displayed on the effect symbol display device 15 when a random number is newly extracted. is there. Note that “prefetch determination processing 1” (FIG. 6) has substantially the same subroutine processing as “correction determination processing 1” shown in FIG. 7, and will be described after “correction determination processing 1”.
In S204, the extracted various random numbers are stored in the memory of the main controller 30 as the reserved storage in FIG. 1 (maximum of four).

  In the subsequent processes of S205 to S209, as in the process on the start port 1 side, the entrance of the start port 2 is confirmed, various random numbers including the second random number are extracted, the second random number is prefetched, The reserved memory of FIG. 2 is stored.

  As shown in FIG. 7, in “win / fail determination process 1” for determining whether or not to substantially shift to a special game, first, it is confirmed whether or not there is a reserved memory in FIG. 2 (S 401), and there is a reserved memory. If yes (yes), the hold storage of FIG. 2 is shifted (S402). This process is the storage with the oldest storage (target storage rank 1), which is the object of determination of success / failure, and is moved from the storage 1 to, for example, a register when determination of success / failure is made. Along with this, the storage in the storage area is shifted as follows: storage 4 → holding storage 3, storage 3 → holding storage 2, storage 2 → holding storage 1. This shift process creates a free space in the reserved storage area (increases when there is already a free space), thus enabling a new reserved storage.

  If there is no reserved memory in FIG. 2 in S401 (no), it is confirmed whether there is a reserved memory in FIG. 1 (S403), and if there is a reserved memory (yes), the reserved memory in FIG. 1 is shifted. (S404). As described above, in the present embodiment, priority is given to the determination of whether or not the second start port 22B is correct over the first start port 22A.

  After the shift process of the special figure 2 or the special figure 1, it is confirmed whether or not the probability change is in progress (the probability change flag = 1 during the probability change) (S405). If the probability change is not in progress (yes), the loop count is set to 2. If the probability change is in progress (no), the loop count is set to 4. The “number of loops” means that in the “correction determination process 1”, a determination process is executed to determine whether or not the first or second random number matches the determination value for each stage of the correctness determination table. This indicates the number of steps in the determination table to be looped.

  After setting the number of loops, in S408, the first or second random number stored in the memory is transferred to the CPU as a comparison value (load), and a stored random number determination process is performed (S409).

  As shown in FIGS. 8 and 9, the “stored random number determination process” first loads the content stored in the reference address 00H as the lower data (lower digit) of the determination value from the first stage of the success / failure determination table ( Along with (S501), the contents of the reference address 01H are loaded as the upper data (upper digit) of the determination value (S502). As a result, the upper limit value of the determination value at the first stage of the success / failure determination table is set.

  Then, the comparison value is compared with the upper limit value of the first-stage determination value, and it is determined whether or not the comparison value is larger than the determination value (S503). If the comparison value is smaller than the determination value (no), then the content of the reference address 02H is loaded as lower data (lower digit) of the determination value from the first stage of the success / failure determination table (S504) and the determination value The contents of the reference address 03H are loaded as the higher-order data (S505). As a result, the lower limit value of the determination value at the first stage of the success / failure determination table is set.

  Subsequently, the comparison value is compared with the lower limit value of the first-stage determination value, and it is determined whether or not the comparison value is equal to or greater than the determination value (S506). If the determination result is yes, the comparison value, that is, the random number matches the determination value within the range of the first stage of the success / failure determination table, and whether or not the special game is successful is determined to be a hit determination. The return value stored at the address 04H is loaded, and since it is already a win, the loop count is set to 0 (S508), and the “stored random number determination process” is terminated.

  If the determination result of S506 is no determination, this is because the comparison value is smaller than the lower limit value of the first stage of the determination table, that is, the minimum value of the determination table, so there is no possibility of winning, and the loop count is set to zero. (S508) and the “stored random number determination process” is terminated.

  If the comparison value is larger than the determination value in the processing of S503 (yes), 1 is subtracted from the loop count (S509), whether the loop count is 0 (S510), and if the loop count is 0 (yes). The “stored random number determination process” is terminated.

  If the number of loops is not 0 (no), the stage of the success / failure determination table is shifted by one stage, and the determination process of the second stage is executed in the same manner as the first stage.

  As described above, in the “stored random number determination process”, the upper limit value and the lower limit value of the determination value are compared with the comparison value (first or second random number) at each stage of the success / failure determination table, and within the determination value range. If there is a comparison value, if it is determined that there is a comparison value, a hit determination is made. If it is determined in the first step that the comparison value is smaller than the minimum determination value, the processing is immediately terminated.

  In S410 of FIG. 7, the return value set in S507 (FIG. 8) of the “stored random number determination process” is stored in the CPU, whether the return value is 7 (S411), and if the return value is 7 (yes) ), A jackpot setting process is executed (S412), and if the return value is not 7 (no), a loss setting process is performed (S413).

  In the big hit setting process (S412) and the disparity setting process (S413), selection of a variation pattern based on the random number for variation pattern determination, confirmation of the hit symbol of Special Figure 1 or Special Figure 2 based on the random number for big hit symbol determination, In the case of a loss, the determination of the failure symbol of FIG. 1 or FIG. 2 is executed based on the random symbol for determining the failure symbol, and the command is transmitted to the sub-integrating device 35, and also the special controller 1 or FIG. The display devices 16 </ b> A and 16 </ b> B of FIG. 2 are directly controlled, and a process of setting 1 to the changing flag of the main control device 30 is executed.

  In “look-ahead determination process 1” shown in FIG. 6, the loop count is set to 2 (S301), the first or second random number is loaded as a comparison value (S303), The “stored random number determination process” is executed (S303). Based on the determination result, the effect symbol display device 15 is caused to execute an effect display mode including a hit notice. In the “prefetch determination process 1”, the game state changes from the gaming state at the time of the prefetch determination, and the problem is that the game state is different at the beginning of the change, that is, the probability change (high probability) state at the time of prefetching. However, if it returns to the normal probability (low probability) at the time of fluctuation, the look-ahead determination does not make sense, and in order to avoid this, the loop count according to the current gaming state is not used, and the loop count at the low probability (2 times) ) Is set.

  In the “symbol determination process 1” shown in FIG. 10, the value of the open / close flag indicating the opening pattern of the big winning opening during the big hit game or after the big hit game is ended based on the determined special figure 1 or special figure 2 data. The process of setting the value of the mode flag for setting the gaming state of is executed. In this process, it is confirmed whether Special Figure 1 or Special Figure 2 is fluctuating (flag is fluctuating = 1) (S601). If fluctuating (no), it is confirmed whether the fluctuating time has elapsed. (S602) If the variation time has elapsed (yes), the variation flag is set to 0 (S603), the effect symbol confirmation instruction signal is transmitted to the sub-integrating device 35 (S604), and the variation of the special diagram is detected. After stopping, 1 is set to the in-confirm flag (S605).

  Check whether the special figure finalizing flag is 1 (S606), if 1 (yes), check whether the special figure finalization time has passed (S607), and if it has passed (yes), the finalizing flag Is set to 0 (S608). The subsequent processing will be described with reference to FIG. 10 together with the special diagram and the diagram showing the jackpot type in FIG. 11 and the diagrams showing the operation status of various functions. It is confirmed whether the special figure 1 or the special figure 2 is a winning symbol (S609), and if it is a winning symbol (yes), it is confirmed whether it is a 2R symbol (S610).

  If it is not a 2R symbol (S610: no), the open / close flag is set to 1 (S611), and it is confirmed whether the symbol is a low probability symbol (S612). If the symbol is not low (no), the mode flag is set to 0 (S613). If the symbol is low (yes), the mode flag is set to 1 (S614), and the big hit flag is set to 1 (S614). S619).

  If it is a 2R symbol in S610 (yes), 2 is set in the open / close flag (S615), and if it is a low probability symbol (S616), if it is not a low probability symbol (no), 2 is set in the mode flag. (S617) If the symbol is a low probability (yes), 3 is set in the mode flag (S618), and 1 is set in the big hit flag in S619.

As shown in FIG. 11 (A), the pachinko machine determines the type of special game according to the type of special figure 1 or special figure 2 that has been confirmed. In this case, the type of special game is defined by the open / close flag 1, and the opening of the grand prize opening 25 for 28 seconds or 1 round until the number of entered balls reaches the specified number is continued for 15 rounds and the time reduction function is activated. A special bonus game, the same special winning opening 25 is opened, and the bonus winning game 25 is open and closed for 2 seconds. The jackpot special game to be executed is selected from the four types of jackpot special games which execute the opening operation of the same big winning opening 25 and operate the probability changing function.
Also, as shown in FIG. 11B, depending on the type of special figure 1 or special figure 2 that has been confirmed, high probability function (probability change), variable time shortening function (short time), open time extension function, and probability notification Various functions are selected.

  According to the pachinko machine of the present embodiment, the success / failure determination table is divided into a plurality of stages, and for each stage, a lower limit value and an upper limit value are set, and a range consisting of a plurality of judgment values continuous between them. Configured. In the success / failure determination process, the number of loops is determined depending on whether the gaming situation is low probability or high probability, and based on the number of loops, the first or second start ports 22A and 22B are connected to the plurality of stages of the determination table. The first or second random number extracted due to the entry is compared with the determination value. That is, when the probability is low, the number of loops is set to 2 and compared with the first and second steps of the success / failure determination table, and when the probability is high, the number of loops is set to 4 and the first to fourth steps of the success / failure determination table. Compared with.

  Accordingly, since the range of the determination value compared with the random number is reduced or expanded in response to the change in the probability of the game progress status, the probability of the success / failure determination can be efficiently changed according to the game progress status. In this pachinko machine, the judgment value of the first stage of the success / failure judgment table is five of 773 to 777, the second stage is 5 of 1773 to 1777, the third stage is 45 of 2733 to 2777, and the fourth stage is 3733. It is 45 of -3777, and the hit probability is 10 times higher at the high probability than at the low probability. There are 4000 random numbers from 0 to 3999, and the jackpot probability is 1/400 at the low probability and 1/40 at the high probability.

  Also, in the success / failure determination process, the random number is compared with the upper limit value and the lower limit value for each stage to determine whether they are within the range of each stage. If it is smaller than the minimum value, the determination process is immediately terminated, and further, the process of the program process is reduced by performing the common sub-ruletin process in the actual success / failure determination process and the prefetch determination, The processing speed can be improved to reduce the processing load on the main controller 30, and the capacity of the ROM (program storage medium) can be reduced.

  Further, the success / failure determination table does not need to be provided with a low-probability determination table for high probability and a high-probability determination table, and the determination table determines the lower limit value and the upper limit value for each stage. What is necessary is just to memorize | store in the predetermined | prescribed reference address for the memory | gap determination table of a memory, and can reduce the memory (memory | storage) capacity | capacitance for a power determination table.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The basic structure of the present embodiment is almost the same as that of the first embodiment, and differences will be mainly described. In the pachinko machine according to this embodiment, a big hit game and a small hit game are set as special games. As shown in FIG. 13, the success / failure determination table used in this pachinko machine is divided into four stages, and is composed of two big hit determination stages and two small hit determination stages. The first and third stages are for big hits, and the second and fourth stages are for small hits.

  FIG. 12 shows the “win / fail determination process 2” executed by the pachinko machine. This determination process is set to 2 times if the progress of the game is in a low probability state, and is set to 4 times if it is in a high probability state (S426, similar to “Win / Noness determination process 1” (FIG. 7)). S427). In the stored random number determination process (S429), the determination is executed by the subroutine process ("stored random number determination process") shown in FIG. 8 as in the first embodiment. When the determined number of loops is 2, the first and second stages of the success / failure determination table are looped through all stages of the success / failure determination table when the number of loops is four. Loop alternately with the stage. When the big hit is made at the first stage or the third stage, the return value is set to 7, and when the big hit is made at the second stage or the fourth stage, the return value is set to 3 (see FIG. 13).

  In “win / fail determination process 2”, it is confirmed whether the return value is 7 (S 431). If it is 7 (yes), the big hit setting process is executed (S 432). On the other hand, if the return value is 3 (S433), the small hit setting process is executed (S434), and if the return value is neither 7 nor 3, the loss setting process is executed (S435). After that, a big hit special game or a small hit special game is executed based on the set return value.

  FIG. 14 shows “symbol determination processing 2” executed by the pachinko machine. As in “symbol determination process 1” (FIG. 10), this determination process determines whether the special symbol 1 or special symbol 2 is a winning symbol (S629), whether it is a big hit symbol or a small bonus symbol (S630). If so (yes), it is confirmed whether or not it is a 2R symbol (S631).

  If it is not a 2R symbol (S631: no), 1 is set in the open / close flag (S632), and if it is not a low probability symbol (S633: no), 1 is set in the mode flag (S634). If (S633: yes), the mode flag is set to 2 (S635). In either case, after setting the mode flag, 1 is set in the big hit flag (S640).

On the other hand, if the symbol is 2R (S631: yes), 2 is set in the open / close flag (S636). If the symbol is not low probability (S637: no), 3 is set in the mode flag (S638). If so (yes), the mode flag is set to 4 (S639), and then the jackpot flag is set to 1 in S640.
If it is a small hit symbol in S630 (no), the open / close flag is set to 3 (S641), the small hit flag is set to 1 (S642), and the mode flag is set to 0 (S643).

As shown in FIG. 15 (A), this pachinko machine has four types defined in the open / close flags 1 and 2 as in the first embodiment, depending on the types of special figure 1 or special figure 2 that have been confirmed. The special game is selected from five types including the special game of small hits and the special game of small hits that are defined in the open / close flag 3 and open the big winning opening 25 twice for 0.3 seconds.
Further, as shown in FIG. 15B, similar to the first embodiment, various functions such as probability variation, time reduction, open time extension function, and probability notification are selected according to the type of the special figure 1 or the special figure 2. Note that none of the functions is activated in the small bonus special game in which the mode flag is 0.

  According to the present embodiment, the same effect as in the first embodiment can be obtained with respect to the success / failure determination process, and the hit determination table is provided with a stage for big hit and a stage for small hit, and at which stage the hit is made. The big hit game and the small hit game are determined by. Therefore, determination of success / failure and selection of game type (big hit, small hit) can be made at the same time, and the efficiency of program processing by the main controller 30 is improved.

  Since the number of loops is set to 2 or 4 depending on whether the game progress status is low probability state or high probability state, either big hit or small hit compared with random numbers according to the fluctuation of the probability of the game progress status The range of the determination value can be reduced and expanded, and the success / failure probability of either big hit or small hit can be changed efficiently. The success / failure determination table includes 10 judgment values for the first stage big hit, 768 to 777, 10 judgment values for the second stage small hit, 1768 to 1777, and 2688 to 2777 for the third stage big hit. 90, and the fourth stage small hits are 10 from 3768 to 3777, and the big hit probability is 10 times and the small hit probability is doubled when the probability is high compared to when the probability is low.

  Next, a third embodiment of the present invention will be described with reference to FIGS. The basic configuration of the present embodiment is the same as that of the first and second embodiments, and differences will be mainly described. As shown in FIG. 19, the two types of success / failure determination tables for the low probability and the high probability are set as the success / failure determination table of the present embodiment. Each success / failure determination table is divided into four stages, and the first stage and the second stage are stages for big hits, and the third stage and the fourth stage are stages for small hits. In the high / low probability determination table, the range of determination values at each stage is set wider than that of the low probability determination table.

  In “holding storage process 2” shown in FIG. 16, if there is a ball entering the start port 1 (S221) and the number of holdings does not reach the maximum value (S222), 1 is set in the special flag (S223). Subsequently, various random number extraction processing is performed (S224), prefetch determination processing is performed (S225), and various random numbers are stored as pending storage (S226).

  Next, if there is a ball entering the starting port 2 (S227) and the number of holds is not the maximum value (S228), 2 is set in the special figure flag (S229). Then, various random number extraction processing is performed (S224), prefetching determination processing is performed (S225), and various random numbers are stored as reserved storage (S226).

  In “prefetch determination process 2” shown in FIG. 17, it is confirmed whether or not the special figure flag is 2 (S311). If the special figure flag is 2 (yes), the number of loops is set to 2 (S312). If the special figure flag is not 2 (no), the loop count is set to 4 (S313). Thereafter, the prefetch determination is executed based on the low / high probability determination table (S314 to S316).

  In addition, this pachinko machine is provided with an open extension function, and when the open extension function is operated, the special figure 2 mainly fluctuates. Therefore, in the “pre-reading determination process 2”, there is a ball entering the start port 2 and when the pre-reading determination in FIG. 2 is performed, the loop count is set to 2 and the big hit is determined without determining the small hit in the determination table. Make a notice and increase the player's expectation when the notice is made.

  As shown in FIG. 18, in the “win / fail determination process 3”, if there is a special memory of FIG. 2 due to the entrance to the start port 2 (S 451), the special memory of FIG. 2 is shifted (S 452). The number of loops is set to 3 (S453). On the other hand, if there is no special memory in FIG. 2 and there is a special memory in FIG. 1 due to the entrance to the starting port 1 (S454), the special memory in FIG. 1 is shifted (S455), and the number of loops Is set to 4 times (S456).

  Next, it is confirmed whether or not the gaming state is being probabilistic (probability changing flag = 1 during probabilistic change) (S457). If the probability change is not in progress (yes), the success / failure determination table for the low probability is set to the reference address (S458). On the other hand, if the probability change is in progress (S457: no), the success / failure determination table for high probability is set to the reference address (S459).

  Subsequently, the first or second random number is loaded as a comparison value, the “stored random number determination process” (FIG. 8) is executed, and the return value obtained by this determination process is stored in the special figure flag (S460). ~ S462). If the stored return value is 7 (S463), the big hit setting process is performed (S464). If the return value is 3 (S465), the small hit setting process is performed (S466), and the return value is 7 or If it is not 3, the deviation setting process is executed (S467).

  According to the present embodiment, the same effect as in the first embodiment can be obtained with respect to the success / failure determination process, and a ball entering the first start port 22A or a ball entering the second start port 22B is used as a condition. The number of loops is set to 3 or 4, and the decision table for low probability and high probability uses both 1, 2 for big hits and 3 and 4 for small hits. Thus, it is possible to efficiently vary only the probability of the small hit determination at the time of entering the first starting port 22A and at the time of entering the second starting port 22B.

  Further, in this embodiment, the success / failure determination table is set for low probability and high probability, but since both the failure determination tables store the lower limit value and the upper limit value in the memory of the main controller 30 for each stage. Thus, the memory capacity is not increased as in the conventional gaming machine.

  In any of the first to third embodiments, the determination is made in such a manner that the determination is made in a loop from the step with the smaller determination value in the determination table to the step with the larger determination value. It may be configured to loop in order from the smallest to the smallest determination value. In this case, when it is determined that the random number is larger than the maximum determination value in the determination table, the determination process is terminated even if the number of loops remains (even if the number of loops is not 0).
