Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine that includes a symbol display device that displays a symbol in a variable manner and generates a gaming state that is advantageous to a player when the symbol is varied and then stopped in a predetermined display mode. The present invention relates to a gaming machine that changes a probability of occurrence of a special effect mode that increases a player's expectation displayed on a symbol display device according to the number of times.
[0002]
[Prior art]
When the symbol of the symbol display device fluctuates and becomes a predetermined combination (so-called jackpot), in a gaming machine that can obtain a privilege (for example, a jackpot game is performed), the predetermined combination is obtained during the symbol variation. There is a state called reach one step ahead. In the reach state, for example, the symbol display device has three symbols of the first symbol, the second symbol, and the third symbol (left symbol, middle symbol, right symbol), and the first symbol and the third symbol are This is a state in which the robot stops at the same symbol and waits for the final stop symbol (second symbol) to stop. When the player reaches reach, the player can expect the fluctuation to finally become a predetermined combination (a combination of jackpots), resulting in an increase in the interest of the player.
[0003]
By the way, whether or not to reach will depend on a numerical value drawn at random, and the appearance rate of reach is generally set to about 1/15. Since the probability of reach is randomly drawn with a probability of 1/15, if the game is continued, the reach may not occur even if the symbol changes nearly 50 times. If the reach does not occur for a long period of time, the player has doubts about whether or not he can get a big hit, and the interest of the game is reduced, leading to a decrease in the operation of the hall and causing a disadvantage.
[0004]
On the other hand, if the probability of reach is simply set high, the probability of getting a jackpot benefit is a rare event of about 1/360. Sex is lost. Accordingly, the reach does not cause the player to expect a big hit, and the player's interest in the game is reduced.
[0005]
According to Japanese Patent Laid-Open No. 2000-107393, the number of symbol fluctuations after starting or after the end of a big hit until the next big hit occurs is less than 100 times, more than 100 times, up to 200 times, and more than 200 times. By changing the occurrence probability of reach, for example, by changing to 1/5, 1/3, 1/15, the player's sense of expectation for jackpot is increased, and even if the game is continued for a long time A pachinko machine that can attract the player's interest is described.
[0006]
However, the above conventional pachinko machine simply switches the probability of reach when the number of symbol variations reaches a predetermined number of times (to increase or decrease the probability of occurrence), and the number of symbol variations Until the predetermined number of times that the reach occurrence probability is switched, the reach occurrence probability does not change even if the number of symbol fluctuations increases. Further, even if a reach occurs, this does not change the probability of the subsequent reach, and does not change the setting change of the reach occurrence probability in small increments. Furthermore, since this continues to count the number of fluctuations until the big hit in the symbol fluctuation results, it will be out of reach even if reach occurs, and if the big hit is not made for a long time, the number of fluctuations will exceed the above-mentioned predetermined number of times. The reach probability is extremely increased, and conversely, the reach probability is extremely decreased. In either case, the reach will not be a big hit even if the reach occurs frequently. The reliability of the game will be lost or the reach of the game will be reduced because it will hardly reach you.
[0007]
[Problems to be solved by the invention]
The purpose of the present invention is to prevent a player from playing a special effect that reduces the game's taste or the ratio of the special effect in the number of fluctuations because a special effect that increases the player's expectation does not occur. An object of the present invention is to provide a gaming machine that can eliminate the weakening of motivation.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a game board surface provided in a pachinko gaming machine according to an embodiment of the present invention. A symbol display unit 3 in which a symbol display device 2 constituted by a color liquid crystal display device is assembled is disposed substantially at the center of the game board surface 1. The symbol display device 2 displays a plurality of symbol strings as identification information for allowing the player to recognize a hit by the variable display game. Note that the special effect mode described in claim 1 is the occurrence of symbol reach in the variable display game performed in the symbol display device 2 in the present embodiment.
[0012]
The symbol display device 2 is configured to variably display three symbol strings as identification information, and variably displays the left symbol, the middle symbol, and the right symbol from the left side of the display screen. In the lower center of the symbol display unit 3, there is provided a tulip-type ordinary electric accessory 4 having a variable winning opening 5 that is expanded by electromagnetic means such as a solenoid. Note that the variable prize opening 5 of the ordinary electric accessory 4 is set as a start prize opening related to the start of symbol variation in the symbol display device 2.
[0013]
A variable winning device 6 is provided below the ordinary electric accessory 4. The variable winning device 6 includes an opening / closing door 7 provided to be tiltable in the front-rear direction, and the opening / closing door 7 is driven by a solenoid (not shown) provided on the back side of the game board. The variable winning device 6 is normally in a state where the open / close door 7 is closed and a pachinko ball can not be awarded to the big winning opening 8 (a disadvantage to the player). On the other hand, on the symbol display device 2, the left symbol, the middle symbol, and the right symbol are displayed in a variable manner on the basis of the winning of the pachinko ball in the start winning opening 5. Note that the left symbol, the right symbol, and the middle symbol stop at the same time. When the symbols are displayed on the symbol display device 2 in a predetermined display mode, for example, when the combination of the left symbol, the middle symbol and the right symbol which are stopped becomes a big combination, it is advantageous to the player. Then, the variable winning device 6 converts the pachinko ball to the big winning opening 8 into a state where it is easy to win.
[0014]
A special area (not shown) that is a special prize area is provided in a part of the inside of the big winning opening 8, and a specific area door (not shown) that opens and closes the specific area is provided in the specific area. Yes. The special winning opening 8 is in a special game state (big hit game state) when the result of the symbol change stop in the symbol display device 2 is a big hit, and is opened for a predetermined time (for example, 29.5 seconds). Is done. However, the special winning opening 8 is closed when a predetermined number (for example, 10) of winnings is received during opening or when a predetermined time has passed. The above-described opening operation of the big winning opening 8 is referred to as one round of big hit game.
[0015]
In addition, if the game ball passes through the specific area while the special winning opening 8 is opened, the continuation condition is satisfied, and after the special winning opening opened this time is closed, that is, this round After the is finished, the special winning opening 8 is newly opened and the next round is started. The maximum number of consecutive opening operations (number of consecutive rounds) of the grand prize opening 8 based on the passing of a game ball through a specific area has a maximum number of times, for example, up to 15 times (up to 15 rounds) including the first opening. It is up to. In the big hit gaming state, when there is no passing of a game ball to a specific area while the big winning opening 8 is opened, the big winning gaming state ends when the big winning opening 8 is closed. When the continuous opening operation of the big winning opening 8 continues up to the fifteenth time, the big hit gaming state is ended when the fifteenth big winning opening 8 is closed.

[0022]
A main process executed by the main CPU of the main control device 9 in the pachinko gaming machine according to the embodiment configured as described above will be described. In the following description, reach corresponds to a special effect mode that increases the player's expectation based on the operation of the symbol start port described in claim 1. Further, the counting means for counting the number of times that the special effect mode has been achieved in the predetermined number of symbol variations corresponds to the variation frequency counter.
[0023]
FIG. 3 is a flowchart showing a main routine of processing executed by the main CPU. When the power is turned on, the main CPU performs initialization processing, clears the RAM, and sets initial values to various counters and flags necessary for the following processing. The main CPU performs a game process after completing the initialization process, and performs a random number counter update process after completing the game process.
[0024]
In the pachinko machine of this embodiment, there are seven types of counters: a big hit determination counter, a big hit symbol counter, a left symbol counter, a middle symbol counter, a right symbol counter, a reach determination counter, and a variation pattern counter. It is provided, and the value of each counter is read and stored when a start winning is detected, and used for processing related to the start of symbol variation (variable display game) in the game processing.
[0025]
Here, each of the seven types of counters will be described. The big hit determination counter is a counter for determining whether or not the variable display game has been hit, and is cyclically updated one by one within a range of 0 to 320, for example.
[0026]
The big-hit symbol counter is a counter for determining a big-hit symbol when the variable display game hit / fail judgment is a hit (so-called big-hit). The jackpot symbol is a combination of symbols such as 111, 777, AAA, etc. in which the left symbol, the middle symbol, and the right symbol are all the same. In this embodiment, ten types are provided in total. The jackpot symbol counter is cyclically updated one by one within a range of 0 to 9, for example, in correspondence with these jackpot symbols.
[0027]
The counter for the left symbol, the counter for the middle symbol, and the counter for the right symbol are counters for determining the left, middle, and right symbols, respectively, when the variable display game is not successful. Here, to simplify the description, it is assumed that the symbols displayed on the symbol display device 2 are common symbols for the left symbol, the middle symbol, and the right symbol, and ten types are set. The types of symbols will be described as being 1, 2, 3, 4, 5, 6, 7, 8, 9, A, for example. The counter for the left symbol, the counter for the middle symbol, and the counter for the right symbol are cyclically updated one by one within the range of 0 to 9, for example, corresponding to these symbols.
[0028]
The reach determination counter is a counter used for determining whether or not to generate a reach (so-called loss reach) when the variable display game is not successful. In the embodiment, the reach determination counter is updated cyclically, for example, one by one within a range of 0 to 99 (100 values are taken). The variation pattern counter is a counter for determining a variation pattern of symbol variation of the variable display game. In the embodiment, a description will be given assuming that, for example, 50 types of variation patterns are provided. The variation pattern counter is cyclically updated one by one within a range of 0 to 49, for example, in correspondence with the types of these variation patterns.
[0029]
The main CPU increments the counter value by one in the random number counter update process. When the main CPU finishes the random number counter update process, the main CPU returns to the game process. Thus, the main CPU repeatedly executes the game process and the random number counter update process.
[0030]
Next, game processing executed by the main CPU will be described. 4 to 8 are flowcharts of game processing executed by the main CPU. When starting the game process, the main CPU determines whether or not there is a start opening prize (step S01). If there is no winning detection signal from the starting winning detection switch SW1, the main CPU determines that there is no starting opening winning and moves to step S06. When the game ball wins the start winning opening 5, a win detection signal from the start winning detection switch SW1 is input to the main controller 9. The main CPU determines that step S01 has a start opening prize, and proceeds to step S02.
[0031]
When the main CPU proceeds to step S02, the main CPU determines whether or not the number of reserves related to the winning storage at the start winning opening 5 is full (step S02). In the present embodiment, the maximum number of suspensions related to winning storage at the start winning opening 5 is four. The main CPU determines whether or not the value of the start prize counter is 4, and if the value of the start prize counter is 4, the main CPU determines that the holding number is full. In this case, the start prize opening No winning storage is performed for 5, and the process proceeds to step S06. On the other hand, if the value of the start winning counter is not 4, it is determined that the number of reserves is not full, and the process proceeds to step S03 to store a winning in the start winning port 5. The start winning counter is a counter that is incremented by one every time the winning winning opening 5 is memorized. The initial value is 0, and the range of possible values is 0 to 4.
[0032]
In step S03, the main CPU obtains the current values of the jackpot determination counter, the jackpot symbol counter, the left symbol counter, the middle symbol counter, the right symbol counter, the reach determination counter, and the variation pattern counter. (Step S03) Each acquired counter value is stored in a predetermined acquired value storage area corresponding to the value of the start winning counter (in this case, 0 to 3) (Step S04).
[0033]
FIG. 9 is a diagram showing a predetermined acquired value storage area in which each counter value acquired corresponding to the value (0 to 3) of the start winning counter is stored. As shown in FIG. 9, when the value of the start winning counter is 0 (no start winning is stored), each acquired counter value is stored in the acquired value storage area (1). Similarly, when the value of the start prize counter is 1, each acquired counter value is stored in the acquired value storage area (2), and when the value of the start prize counter is 2, each acquired value is stored. The counter value is stored in the acquired value storage area (3). When the value of the start winning counter is 3, each acquired counter value is stored in the acquired value storage area (4). When the main CPU stores each acquired counter value in a predetermined acquired value storage area, the main CPU increases the value of the start winning counter by one (step S05), and proceeds to step S06.
[0034]
In step S06, the main CPU determines whether or not it is possible to start symbol variation (start of variable display game) (step S06). In the case of a symbol change, an interval time until the next symbol, or a big hit game, a new symbol change cannot be started. In this case, the process proceeds to a symbol change process. On the other hand, the main CPU proceeds to step S07 when the symbol variation can be started (variable display game is started).
[0035]
In step S07, the main CPU determines whether or not there is a start winning memory (step S07). That is, the main CPU determines whether or not the value of the start winning counter is not zero. If the value of the start prize counter is 0, the main CPU determines that no start prize is stored, ends the game process, and returns to the main routine.
[0036]
On the other hand, in step S07, if the value of the start winning counter is not 0, the main CPU determines that the start winning is stored, and proceeds to step S08, and processing related to the start of symbol variation (start of variable display game). I do. First, the main CPU reads each acquired numerical value (each count value) stored in the acquired value storage area (1) to the determination numerical value storage area (step S08), and acquires the acquired value storage area (2) to the acquired value storage area ( The contents of 4) are sequentially shifted from the acquired value storage area (1) to the acquired value storage area (3), and the acquired value storage area (4) is cleared to an empty state (step S09). Next, the main CPU decrements the value of the start winning counter by one in accordance with the start of the current symbol variation (step S10), and proceeds to step S11.
[0037]
When proceeding to step S11, the main CPU determines whether or not the acquired value for determining the big hit in the determination numerical value storage area is a value (whether it is a big hit decision value) or not (step S11). When determining whether or not the game is a big hit in step S11, if the pachinko gaming machine adopts probability variation, a plurality of jackpot determination values (for example, five) are set at a high probability, and a big hit is determined at a normal probability. For example, by setting the value to one, it is easy to hit in the case of high probability. If the result of the big hit determination is a win in step S11, the main CPU determines that it is a big win and proceeds to step S40. On the other hand, if the result of the big hit determination is not a win, the main CPU determines that it is out and moves to step S12. .
[0038]
First, the case where it is determined in step S11 that it has come off will be described. The main CPU proceeds to step S12, clears the big hit flag to 0 in response to the disconnection (step S12), and proceeds to step S13. The main CPU increases the value of the variation counter by one in response to the start of the current symbol variation (step S13), and proceeds to step S14. Note that the initial value of the variation counter is set to “0” by the initialization process. In step S14, the main CPU determines whether or not the value of the variation counter exceeds a predetermined number (for example, 50 times) (step S14). In the present embodiment, the probability of causing the special effect mode (reach) is not changed until the number of fluctuations immediately after the initialization process exceeds a predetermined number (50 times).
[0039]
If the value of the variation counter does not exceed a predetermined number (for example, 50), the main CPU determines that step S14 is false and proceeds to step S15. In step S15, the main CPU determines whether or not the combination of symbols to be displayed this time is an out-of-combination combination. That is, it is determined whether or not the acquired values of the left symbol, the middle symbol, and the right symbol in the determination numerical value storage area are all the same value (step S15), and the acquired values of the left symbol, the middle symbol, and the right symbol are all the same. If it is a value, in order to make it a missing symbol in accordance with the detachment determination, the acquired numerical value of the middle symbol is shifted, for example, by +1 (step S16), and the process proceeds to step S17, while the left symbol, middle symbol, right symbol If the acquired numerical values are not all the same value, the combination of symbols to be displayed this time is a combination that is out of place, and the process proceeds directly to step S17. In step S17, the main CPU determines the left stop symbol, the middle stop symbol, and the right stop symbol based on the acquired values of the left symbol, middle symbol, and right symbol in the numerical value storage area for determination.
[0040]
Next, the main CPU determines whether or not the combination of symbols to be displayed this time is a combination that generates reach. That is, the main CPU determines whether or not the acquired numerical value of the left symbol and the acquired numerical value of the right symbol in the determination numerical value storage area are the same (step S18). When the acquired numerical value of the left symbol and the acquired numerical value of the right symbol in the determination numerical value storage area are the same, the main CPU determines that a reach has occurred, and the number of fluctuations in the reach occurrence status storage buffer as shown in FIG. A value “1” that defines “reach occurrence” is stored in the storage area corresponding to (step S19), and the process proceeds to step S21.
[0041]
On the other hand, if the acquired value of the left symbol and the acquired value of the right symbol in the determination numerical value storage area are not the same in step S18, the main CPU determines that there is no reach, and the reach occurrence state as shown in FIG. A value “0” defining “no reach” is stored in the storage area corresponding to the number of fluctuations in the storage buffer (step S20), and the process proceeds to step S21.
[0042]
In addition, as shown in FIG. 12, the storage area of the reach occurrence status storage buffer is provided for 50 times from the status storage area (1) to the status storage area (50) corresponding to the number of fluctuations. The situation (reach occurrence or no reach) can be stored a predetermined number of times (in this embodiment, 50 times). Also, every time the symbol changes, the status of the symbol change is memorized from the status memory area (1). When the status memory area (50) is filled and the memory is full, it is memorized again from the status memory area (1). To go.
[0043]
When the main CPU proceeds to step S21, the main CPU determines the variation pattern based on the obtained numerical value for the variation pattern in the determination numerical value storage area (step S21), and the display CPU (display control device 55) determines the stop symbol and the variation. The pattern is transmitted (step S22), the game process is finished, and the process returns to the main routine.
[0044]
Next, the case where it is determined in step S11 that a big hit will be described. If the main CPU determines that it is a big hit, the main CPU proceeds to step S40, sets a big hit flag corresponding to the big hit (step S40), and increases the value of the fluctuation counter by one corresponding to the start of the current symbol fluctuation ( The process proceeds to step S41) and step S42. The main CPU determines the jackpot symbol (same symbols for the left, middle, and right symbols) based on the acquired value for the jackpot symbol in the judgment value storage area (step S42), and for the variation pattern of the judgment value storage area The variation pattern is determined based on the obtained numerical value (step S43), and in the case of a big hit, reach always occurs in the process of stopping the symbol, so the reach occurrence state as shown in FIG. 12 corresponding to the reach occurrence A value “1” that defines “reach occurrence” is stored in a storage area corresponding to the number of fluctuations in the storage buffer (step S44), and a stop symbol and a fluctuation pattern are transmitted to the display CPU (display control device 55). (Step S45), the game process ends, and the process returns to the main routine.
[0045]
As described above, when the main CPU determines the variation pattern and the stop symbol according to the big hit / loss, it sends a command of the variation pattern type to the display control device 10, and the left symbol, right symbol, middle symbol Send a stop symbol for the command. When receiving the variation pattern type command, the display control device 10 starts symbol variation of the left symbol, the middle symbol, and the right symbol. Further, the display control device 10 determines the timing of symbol variation (variation speed switching timing, symbol fluctuation start timing, etc.) corresponding to the type of variation pattern, and further includes the left symbol, middle symbol, and right symbol. When the stop symbol command is received, the stop symbol of the left symbol, the right symbol, and the middle symbol corresponding to these is determined. In addition, when the stop symbol commanded to the display control device 10 is a reach symbol, reach occurs.
[0046]
On the other hand, when the next game process is performed, the main CPU determines that the determination process of whether or not the symbol variation can be started as a result of the symbol variation following the processing of step S01 to step S06 is false, and step S50. Then, step S50 is determined to be true, and the process proceeds to step S51 to monitor whether or not the variation time corresponding to the determined variation pattern has elapsed (step S51). If the variation time has not elapsed, the main CPU ends the game process and returns to the main routine.
[0047]
When the main CPU determines that the variation time has elapsed, the main CPU transmits a symbol stop command to the display CPU (step S52), and determines whether or not it is a big hit (whether or not the big hit flag is set). A determination is made (step S53). If the game is a big hit, the big hit game process in step S54 is performed. If the big hit is not, the game process is terminated and the process returns to the main routine. Note that the jackpot process is substantially the same as the conventional process and is not directly related to the gist of the present invention, so the description thereof is omitted.
[0048]
As is clear from the above description, when the number of fluctuations immediately after the initialization process exceeds a predetermined number (50 times), a reach is generated when it is determined that the hit in step S11 is a big hit or not. Whether or not to perform a reach occurs when the acquired value of the left symbol and the acquired value of the right symbol are the same according to the acquired value of the left symbol and the acquired value of the right symbol in the determination numerical value storage area. In the case of this embodiment, there are 10 combinations of the left symbol, middle symbol, and right symbol, respectively, so the total number of combinations of symbols is 1000, 10 × 10 × 10. Of these, since there are 10 types of jackpot symbols, the total number of combinations of outliers is 990. Of these, the combinations of symbols that generate reach (referred to as reach symbols) are combinations in which the left symbol and right symbol are the same and the middle symbols are different (for example, “1, 2, 1” to “1, A, 1”). There are 90 ways of 10x9. Accordingly, the probability of occurrence of a reach that is out of place is 90/990 (the reach occurrence probability is not changed).
[0049]
As described above, one process for symbol variation is completed. When the main CPU determines in the next game process that the start prize is stored in step S07, the next symbol variation is newly started. Then, as described above, every time symbol variation is performed, the symbol variation status (either reach occurrence or no reach) is stored from the status storage area (1), and the variation count is 50th. When the situation storage area (50) is stored, the storage area of the reach occurrence situation storage buffer becomes full.
[0050]
Eventually, the number of fluctuations immediately after the initialization process exceeds a predetermined number (50 times). In the case where the number of fluctuations immediately after the initialization process exceeds a predetermined number (50 times), the process in the case where the determination result of whether or not the big hit is made in step S11 is a big hit, the number of fluctuations exceeds the predetermined number (50 times). The processing is the same as the processing up to, but the processing in the case where the determination result of whether or not the big hit in step S11 is out of place is different.
[0051]
A case will be described in which it is determined in step S11 that the number of fluctuations exceeds a predetermined number (50 times). The main CPU proceeds to step S12, clears the big hit flag to 0 in response to the departure (step S12), increases the value of the variation counter by 1 in response to the current symbol variation start (step S13), Proceed to S14. In the process of step S14, the main CPU determines that the value of the variation counter exceeds a predetermined number (for example, 50 times), and proceeds to step S23.
[0052]
In step S23, the main CPU determines whether or not the combination of symbols to be displayed this time is an out-of-combination combination. That is, it is determined whether or not the acquired values of the left symbol and the right symbol in the determination numerical value storage area are the same value (step S15), and the acquired value of the left symbol matches the acquired value of the right symbol. In this case, in order to change the right symbol acquisition value, for example, by +1 (step S24) and proceed to step S25 in order to make a symbol out of accordance with the determination of detachment, the left symbol acquisition value and the right symbol acquisition value If they are not the same value, the combination of symbols to be displayed this time is a combination that is out of place, and the process proceeds directly to step S25.
[0053]
In step S25, the main CPU reads a determination value from the reach table on the basis of the acquired numerical value for reach determination in the determination numerical value storage area (step S25).
[0054]
FIG. 10 is a diagram showing, in a tabular form, determination values used in a lottery to determine whether or not to generate a reach (losing reach) stored in the reach table. As shown in FIG. 10, the number of determination values stored in the reach table is 100 corresponding to the range of values 0 to 99 that the reach determination counter can take. For example, when the acquired numerical value of the reach determination counter is “0” to “4”, the determination value “0” is read from the reach table. For example, when the acquisition numerical value for reach determination is “5”, the determination value “1” is read from the reach table. For example, when the acquisition numerical values for reach determination are “14” to “49”, the determination value “10” is read from the reach table.
[0055]
When the main CPU reads the determination value from the reach table, the main CPU proceeds to step S26, and reads the contents stored in the status storage area (1) to the storage status area (50) of the reach occurrence status storage buffer to determine whether a reach has occurred. Then, the number of reach occurrences is counted (step S26). Next, the main CPU obtains a reach determination upper limit value from the number of reach occurrences (step S27). The main CPU compares the read determination value with the reach determination upper limit value and determines whether or not the read determination value is a win (step S28). In the present embodiment, if the read determination value is equal to or less than the reach determination upper limit value, the winning determination is made and a reach is generated.
[0056]
FIG. 11 is a table showing the relationship between the reach number in the past predetermined number of times (50 times) and the value to which the read determination value is won and the reach probability (condition for the determination value to be win). FIG. As shown in FIG. 11, when the number of reach is 0, the reach probability is 50/100, but when the number of reach is 1, the reach is 2 times, 3 times,..., 9 times. As the number increases by one, the reach probability is configured to gradually decrease to 14/100, 13/100, 12/100,..., 6/100. Further, when the number of reach is 10 times or more, the condition for winning the determination value becomes a constant condition (0 or less), and the reach probability becomes a constant probability (5/100).
[0057]
For example, if the value of the reach number is 5, the condition for winning is 5 or less, and if the determination value read from the reach table is 25, the determination result is out of order, and the determination read from the reach table If the value is 5 or less, the determination result is won.
[0058]
When the determination result in step S28 is not a win, the main CPU changes the symbol change to be performed this time to a stop that does not generate reach, and stops in step S29, and proceeds to step S29 to determine the left symbol, middle symbol, right symbol in the determination numerical value storage area. The stop symbol is determined based on the acquired numerical value (step S29). Next, the main CPU proceeds to step S20 and stores a value “0” defining “no reach” in the storage area corresponding to the number of fluctuations in the reach occurrence status storage buffer as shown in FIG. 12 (step S20). ), Go to step S21.
[0059]
When the main CPU proceeds to step S21, the main CPU determines the variation pattern based on the obtained numerical value for the variation pattern in the determination numerical value storage area (step S21), and the display CPU (display control device 10) determines the stop pattern and variation. The pattern is transmitted (step S23), the game process is finished, and the process returns to the main routine.
[0060]
On the other hand, if the determination result in step S28 is a win, the main CPU changes the symbol variation to be performed this time to a variation that stops at the symbol that causes reach, and proceeds to step S30, where the numerical value of the left symbol in the determination numerical value storage area is acquired. Whether or not the acquired numerical value of the middle symbol is the same (step S30). In the process of step S30, when the reach symbol (the symbol in which the left symbol and the right symbol are the same but only the middle symbol is different) is determined, if the left symbol and the middle symbol are the same symbol, the jackpot symbol is obtained. This is to avoid this.
[0061]
In step S30, if the acquired value for the left symbol and the acquired value for the middle symbol are not the same, the main CPU copies the acquired value for the left symbol to the right symbol (the symbol for the left symbol is used as the symbol for the right symbol, (The design remains the acquired numerical value) (step S32), the process proceeds to step S19. On the other hand, if the acquired numerical value of the left symbol and the acquired numerical value of the middle symbol are the same in step S30, the acquired numerical value of the right symbol is set. Copy to the left symbol (the symbol of the right symbol is the symbol of the left symbol and the middle symbol is the acquired numerical value) (step S31), and the process proceeds to step S19. When the main CPU proceeds to step S19, the main CPU stores a value “1” defining “reach occurrence” in the storage area corresponding to the number of fluctuations in the reach occurrence status storage buffer as shown in FIG. 12 (step S19). The variation pattern is determined based on the obtained numerical value for the variation pattern in the determination numerical value storage area (step S21), and the stop symbol and the variation pattern are transmitted to the display CPU (display control device 10) (step S22). After the game process is completed, the process returns to the main routine.
[0062]
As is clear from the above description, at the start of the current symbol variation (start of the variable display game), no reach occurs when the determination result of the big hit is out and the winning result of the reach is off. In addition, when the symbol change this time (start of the variable display game) is reached, if the determination result of the big hit is out and the winning result of the reach is a win, a reach occurs. As shown in FIG. 11, when the number of reach occurrences in the past 50 times is 0, the reach probability is 50/100, and reach occurs with half the probability. Further, when the number of reach occurrences in the past 50 times is from 1 to 9 times, that is, the reach probability is 14/100, 13/100, 12/100,. It decreases gradually like 6/100. Accordingly, the reach (special effect mode) that increases the player's expectation is low in the number of occurrences in the past 50 times, so the player decreases the game preference or the percentage of reach in the number of fluctuations. As a result, it is possible to eliminate the diminished player's willingness to play. Further, since the reach occurrence probability gradually decreases as the reach number increases by one, the reach occurrence probability can be finely adjusted in small increments.
[0063]
In addition, if the hit / loss judgment result is a big hit, or if the hit / loss judgment result is not and the reach win result is a win, a reach occurs and the number of reach increases by one, so the next reach occurrence Probability gradually decreases. On the other hand, if the reach does not occur continuously, for example, 50 times in the pattern variation, the data that stores the reach status is replaced with the data that defines “no reach” for each variation. Of the 50 symbol variations, the number of reach occurrences gradually decreases one by one, so the probability of reach occurrence gradually increases. Therefore, it is possible to prevent the reach occurrence probability from being extremely increased, or conversely, the reach occurrence probability from being extremely decreased.
[0064]
In the above-described embodiment, whether or not to generate reach when it is determined that the game is a big hit from immediately after the initialization process until the number of symbol fluctuations exceeds a predetermined number (50 times). However, instead of this configuration, reach determination counter-2 (e.g., 0 to 0) is used when the acquired value of the left symbol and the acquired value of the right symbol in the determination numerical value storage area are the same. 14), the value of the reach determination counter-2 is acquired in step S03, and it is determined that step S14 is false. Next, the acquired value of the reach determination counter-2 is won. (For example, “5”) is determined, and a reach can be generated when the player wins. Note that even if this configuration is adopted, it does not depart from the gist of the present invention. In this way, during the period immediately after the initialization process until the number of symbol fluctuations exceeds a predetermined number (50 times), outlier reach can be generated randomly with a probability of 1/15 (fixed).
[0065]
In the embodiment of the present invention, the special effect mode is described as the occurrence of symbol reach in the variable display game performed by the symbol display device 2, but is not limited to this, other than the symbol display device, for example, Special effects may be performed as a sound or lamp notice (a jackpot notice or a reach notice). For example, the special lamp flashes or performs a special effect that generates a special sound.
[0066]
【The invention's effect】
  Claim 1Related gaming machinesAccording to the above, the counting means counts the number of times that the special effect mode has been achieved in the predetermined number of symbol variations, and the changing means determines that the value acquired by the lottery means satisfies a predetermined condition according to the count number by the counting means. Since the ratio of satisfaction is changed, the number of occurrences of special effects that will increase the player's expectation is small among the predetermined number of symbol fluctuations in the past, so the player can reduce the game's taste or the number of fluctuations It is possible to eliminate a decrease in the player's willingness to play due to the small proportion of the special performance mode, and to improve the player's willingness to play.
  When there is a situation storage means for storing a predetermined number of times in a time series of data defining whether or not a special effect mode has been performed each time a symbol variation is performed, the latest data is stored in the situation storage device for each symbol variation In addition, the oldest data is updated to the latest data in time series, and the counting means counts the number of times that the special effect mode is obtained in the predetermined number of symbol variations based on the data stored in the situation storage means. The data defining whether or not the special effect mode acquired with the predetermined number of symbol variations has been performed is constantly updated, and according to the number of times the special effect mode has been achieved with the predetermined number of symbol variations based on the updated data. Since the ratio satisfying the predetermined condition is changed, the probability that the special effect is always performed can be appropriately controlled.
[0067]
According to the configuration of the second aspect, the changing unit gradually decreases the ratio at which the value acquired by the lottery unit satisfies the predetermined condition in response to the increment of the number of reach times by the counting unit. Therefore, when reach occurs, the number of times of reach in the past predetermined number of symbol variations increases by one, so the probability of the next reach occurrence gradually decreases, but conversely in symbol variation, for example, If the reach does not occur ten times in a row, the reach occurrence probability gradually increases because the number of reach occurrences in the past predetermined number of symbol variations decreases, so the reach occurrence probability gradually increases. It is possible to prevent the reach occurrence probability from being extremely lowered, and the reach occurrence probability can be finely adjusted in small increments.
