Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a technique for controlling the progress of a game in a ball game machine.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. Known as a thing.

  The variable display of symbols in the display area is not only a variable display of multiple symbols, but the time of variable display is usually reduced in a state where it is a big hit if one more symbols are aligned, as in the so-called reach screen. For example, an effect is made to increase the player's expectation, such as making it longer. In addition, the player's expectation is enhanced by the effect of giving a story to the variable display by using various characters and motifs in images such as symbols. The variation pattern with the pattern variation display mode and display process is determined by lottery each time a variation of the symbol is started. (See, for example, Patent Document 1). In recent years, there has been an increase in the definition of images on display devices and the influence of development competition, and the number of types of variation patterns prepared for a single model has increased, and the richness and novelty of patterns are the biggest factor affecting the popularity of gaming machines. It is an element. In addition, since a different pattern is selected depending on the difference in the gaming state at that time, the data table that is referred to for selection by lottery from a large number of variation patterns is growing year by year.

While the types of performance increase, the data capacity of the storage media installed in the gaming machine does not necessarily increase in relation to cost control. The need for reduction increases. In particular, the main board is required to reduce the amount of ROM data in units of several bytes, and the cost requirement imposed on the developer is large, and it is difficult to solve by a direct method such as an increase in ROM storage capacity. In addition, from the viewpoint of cost reduction by sharing parts for each model, it is necessary to avoid changing the ROM storage capacity and changing the table structure significantly for each model. Under these circumstances, developers are constantly seeking ways to enhance the staging effect while avoiding an increase in the amount of data.
JP 2003-230714 A

  Here, as a developer, when designing the development of a game effect, a situation occurs in which a variation pattern due to a specific effect is desired to be displayed at a desired timing. However, if the ROM storage capacity is already imminent and we want to reduce data even a little, if we increase the number of reference tables just to select a specific variation pattern at a certain timing, further ROM imminence This is undesirable in terms of design.

  The present invention has been made in view of these problems, and an object thereof is to appropriately control a game while suppressing an increase in the amount of data in a ball game machine.

  In order to solve the above-described problems, a ball game machine according to an aspect of the present invention includes a game board on which a game area is formed, a start prize opening provided at a predetermined position in the game area and into which a game ball can enter. , The result of the lottery and the lottery means for executing the lottery for determining whether or not to shift to the special game that is more advantageous to the player than the normal game, triggered by entering the starting winning opening In order to select a variation pattern in which the variation process of the symbol in the variation display is determined from a plurality of variation patterns, the symbol display device in which the symbol variation display is displayed and the variation display of the symbol is started. A count value that is updated at time intervals is extracted as a random value for a pattern lottery value, and based on the extracted pattern lottery value and the result of the lottery determination, fluctuations associated with the pattern lottery value are extracted. The symbol variation determining means for selecting a turn, the display control means for controlling the variation display of the symbols on the symbol display device according to the selected variation pattern, and the result of the lottery win, and the symbol is stopped at a predetermined winning symbol. Special game control means for executing a special game when played.

  The various processes in the winning / failing lottery means and the symbol variation determining means are executed by the central processing unit, and the central processing unit is interrupted as a main loop process to be repeatedly processed and a temporary execution instruction to be executed in the main loop process. The symbol variation determination means causes the central processing unit to execute an initialization process for returning the count value to a predetermined initial value at a predetermined timing as an interrupt process. , Causing the central processing unit to execute a process for extracting a lottery value for a pattern at a specific timing and a predetermined periodic timing thereafter as an interrupt process, and a variation time of a specific variation pattern among a plurality of variation patterns and a count value The timing to initialize the pattern and the extraction timing of the lottery value for the pattern can be used to extract a specific variation pattern regularly. It is set so as to have the engagement.

  Here, the “pattern lottery value” that is a “random value” may be a value randomly extracted as a software random number, for example. The “pattern lottery value” may be a value obtained by extracting a count value counted up or down at a predetermined time interval at a timing when the “pattern lottery value” should be determined. The “specific timing” may be a timing at which the gaming state shifts to a predetermined specific gaming state, or may be a timing at which a predetermined specific condition is established after shifting to the specific gaming state. Alternatively, it may be a specific symbol change start timing after the transition to the specific game state, or a specific symbol change start timing after returning from the specific game state to the normal game. The “correspondence that regularly extracts a specific variation pattern” may be a correspondence that continuously extracts a specific variation pattern, for example.

  According to this aspect, the initial value of the count value initialized at the specific timing and the regular count value periodically counted from the initialization timing are extracted as the pattern lottery values. On the other hand, the variation time of a specific variation pattern (also referred to as a “specific variation pattern”), the initialization timing of the count value, and the extraction timing of the pattern lottery value have a correspondence relationship that regularly extracts the specific variation pattern. It is set to have. For this reason, the specific variation pattern is selected at the count value initialization timing and the subsequent periodic timing. As a result, the specific variation pattern can be surely selected at the timing intended by the game machine developer without replacing the variation pattern. Thus, the developer can select a variation pattern for displaying a specific effect or a variation pattern for displaying a symbol variation at a specific variation time at an intended timing. As a result, it is not necessary to prepare a special pattern determination table only for selecting a specific variation pattern, and a useless increase in data amount can be avoided.

  The specific timing may be set as a predetermined timing at the end of the special game or after the end. According to this aspect, it is possible to intentionally display the symbol variation according to the specific variation pattern in the normal game after the end of the special game. In the specification where symbol variation is reserved during a special game, winning lottery opportunities (holding balls) are accumulated by entering the starting prize opening during the special game, so a specific variation pattern is continued after the special game ends. Making it easier to select.

  The symbol variation determining means performs the process of extracting the pattern lottery value as an interrupt process, on the condition that there is a ball entering the start winning opening that triggers the symbol variation display until the execution. It may be executed. This aspect may mean that the determination of whether or not the lottery value is on hold is made when the count value initialization process is executed in the interrupt process for executing a specific game control process. As a result, the process of extracting the pattern lottery value is executed following the count value initialization process, and the pattern lottery value associated with the specific variation pattern is extracted at the timing intended by the developer. Can be generated. In particular, in the aspect in which the count value initialization process is included in the interrupt process for executing the special game end process, the winning lottery value is likely to be held during the special game, and therefore the specific variation pattern is continued. It becomes easy to extract a lottery value for a pattern associated with.

  Specifically, a reference counter that updates a reference count value as a count value and a reference counter that updates a reference count value having a different period from the reference count value may be provided. The symbol variation determining means causes the central processing unit to execute a process of returning both the reference count value and the reference count value to each initial value in accordance with a specific timing as an interrupt process as an initialization process, and the reference count value is an initial value. Each time a specific value that is an integer multiple of the difference between the upper limit value of the reference count value and the upper limit value of the reference count value is updated, the pattern lottery value is extracted as an interrupt process. The apparatus may be executed.

  According to this aspect, the number of updates of the reference count value until the reference counter is initialized is set to be different from the number of updates of the reference count value until the reference counter is initialized. For this reason, every time the reference counter is initialized after the specific timing, the difference between the count values of the reference counter and the reference counter regularly changes. Here, paying attention to the regular change of the difference, the pattern lottery value is extracted every time the specific value whose difference is an integral multiple of the difference between the upper limit values of the two count values is updated. Thereby, the specific variation pattern can be extracted at a periodic timing at which the reference counter is initialized a plurality of times. That is, by providing a reference counter in addition to the standard counter, a specific variation pattern can be extracted every time the standard counter is initialized, not every time it is initialized. That is, the extraction timing of the specific variation pattern can be arbitrarily set by a combination of the count upper limit value of the reference counter and the count upper limit value of the reference counter. As a result, the degree of freedom in setting the variation time of the specific variation pattern is increased, and it is easy to design an effect to be displayed corresponding to the specific variation pattern. Note that the update timing (count timing) of the reference counter and the update timing (count timing) of the reference counter may be set to be the same or different.

  Another aspect of the present invention is also a ball game machine. This ball game machine is usually provided with a game board in which a game area is formed, a start winning opening provided at a predetermined position in the game area, and a ball entering the start winning opening, A winning / not determining lottery for determining whether or not to shift to a special game that is more advantageous to the player than the game, and a symbol display device for variably displaying a symbol for indicating the result of the winning / failing lottery In order to select a variation pattern in which the variation process of the symbol in the variation display is determined from a plurality of variation patterns when starting the variation display of the symbol, the count value updated at a predetermined time interval is a random value. A pattern variation determining means for extracting a variation pattern associated with the pattern lottery value based on the extracted pattern lottery value and the result of the lottery determination, as a pattern lottery value; A display control means for controlling the display of the symbols on the display device according to the selected variation pattern, and a special game for executing a special game when the result of the lottery wins and the symbol is stopped at a predetermined winning symbol Control means.

  The various processes in the winning / failing lottery means and the symbol variation determining means are executed by the central processing unit, and the central processing unit is interrupted as a main loop process to be repeatedly processed and a temporary execution instruction to be executed in the main loop process. The symbol variation determination means causes the central processing unit to execute an initialization process for returning the count value to a predetermined initial value at a predetermined timing as an interrupt process. , Causing the central processing unit to execute a process for extracting a lottery value for a pattern at a specific timing and a predetermined periodic timing thereafter as an interrupt process, and a variation time of a specific variation pattern among a plurality of variation patterns and a count value The initialization timing of and the number of updates of the count value that becomes the pattern lottery value corresponding to the specific variation pattern are specified. The variation pattern is set to have a relationship to regularly extraction.

  The meanings of terms such as “pattern lottery value” and “specific timing” here are as described above. Also in this aspect, the initial value of the count value initialized at the specific timing and the regular count value periodically counted from the initialization timing are extracted as the pattern lottery values. On the other hand, the fluctuation time of a specific fluctuation pattern (also referred to as “specific fluctuation pattern”), the initialization timing of the count value, and the number of times the count value is updated as the pattern lottery value corresponding to the specific fluctuation pattern The correspondence is set so that patterns are extracted regularly. For this reason, the specific variation pattern is selected at the count value initialization timing and the subsequent periodic timing. As a result, the developer can select a variation pattern for displaying a specific effect or a variation pattern for displaying a symbol variation at a specific variation time at an intended timing. At that time, it is not necessary to prepare a special pattern determination table only for selecting a specific variation pattern, and a useless increase in data amount can be avoided.

  It should be noted that any combination of the above-described constituent elements, or the constituent elements and expressions of the present invention may be mutually replaced between methods, apparatuses, systems, computer programs, recording media storing computer programs, data structures, etc. This is effective as an embodiment of the present invention.

  According to the ball game machine of the present invention, an effect intended by a game machine developer can be efficiently realized while avoiding an increase in the amount of data.

  The big winning opening 66 is a horizontal rectangular winning opening that is opened as a “big hit” when the special symbol 192 stops in a predetermined manner. The big winning opening 66 is provided above the out opening 58 and the like. The winning detection device 78 of the big winning opening 66 includes a sensor that detects the passage of a game ball.

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided in the approximate center of the game area 52 have a variation of the special symbol 192 on each screen and a decoration linked to the special symbol 192. The variation of the effect image including the symbol 190 is displayed (hereinafter, such display is referred to as “symbol variation” or “variation display”). Here, the special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and the symbol mode when the change display is stopped is determined to be the winning symbol. When the symbol is a symbol, the timing at which the stop symbol is displayed is the jackpot occurrence timing. The special symbol display device 61 is display means composed of, for example, 7 segment LEDs. The effect display device 60 is a liquid crystal display that variably displays the decorative symbol 190 in a manner interlocked with the variation display of the special symbol 192. The decorative symbol 190 is a symbol for visually rendering the lottery result display indicated by the special symbol 192. The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of moving images of symbol variation simulating a slot machine game in the central area of the screen.

  The effect display device 60 is constituted by a liquid crystal display in this embodiment, but may be constituted by a mechanical rotating device such as a drum or other display means such as an LED. Since the special symbol 192 does not necessarily have a role of production, in this embodiment, the special symbol 192 is displayed in an inconspicuous size on the special symbol display device 61 at the lower left of the production display device 60. In the case of adopting a technique in which a decorative role is not displayed and a decorative symbol is not displayed, the special symbol may be displayed on a liquid crystal display such as the effect display device 60. The operation port 68 is provided at the left side position of the game board 50. The operation port 68 includes a passage detection device 69. The passage detection device 69 is a sensor that detects the passage of the game ball to the operation port 68, and generates passage information indicating the passage at the time of passage. The passage of the game ball to the operation port 68 triggers an open lottery for determining whether or not to expand the expansion mechanism of the start port 62. When the game ball passes through the operation port 68, a normal symbol, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. When the normal symbol variation display is stopped after a predetermined time has elapsed, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%.

To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning port 72, the start port 62, and the big winning port 66, the winning ball corresponding to the type of the winning port is paid out to the upper ball plate 15 or the lower ball plate 16. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball. Each winning opening includes a gate type through which a game ball passes. In this application, “incoming”, “entering”, and “winning” include “passing”.

  When the game ball falls into the start port 62, the special symbol 192 and the decorative symbol 190 are variably displayed on the special symbol display device 61 and the effect display device 60. The variable display of the special symbol 192 and the decorative symbol 190 is stopped after the elapse of the display time determined prior to the display. When the special symbol 192 and the decorative symbol 190 at the time of the stop are symbols indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the big prize opening 66 is started. At this time, the decorative pattern 190 simulating the game of the slot machine takes a display mode in which the three patterns are matched. In the special game, the grand prize winning slot 66 is temporarily closed after being opened for about 30 seconds or after 9 or more game balls are dropped. Such opening / closing of the big prize opening 66 is repeated a predetermined number of times, for example, 15 times.

  In the normal game after the end of the special game, a variable time shortening game (hereinafter referred to as “time reduction” as appropriate) that is one of the specific games is started. In the variation time shortening game, the variation time of the special symbol and the decorative symbol is shortened from the normal time. The variation time of the special symbol and the decorative symbol is returned to the original variation time after the variation display of a predetermined variation number is performed. When a special game occurs and the lottery result is a predetermined result, a probability variation game (hereinafter referred to as “probability change” as appropriate), which is one of the specific games, is further started after the special game ends. In the probability variation game, a lottery with a higher win probability than the normal probability state is performed, and a new special game is generated relatively early. Whether or not the lottery result indicates a shift to probability change is not notified to the player until the special game is ended, but is notified to the player in the first design change effect after the special game ends. At this time, there is a specific performance that makes a player's expectation about whether a normal game with both time reduction and probability change or a normal game with only time reduction will start. Displayed in symbol variation. It is notified which normal game is started after the expectation is given in the specific performance.

Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.

  The success / failure lottery means 112 accepts a random number value to determine whether or not to shift to a special game that is more advantageous to the player than the normal game when the game ball enters the start port 62. Get as a value. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. As a random number in the present embodiment, an update for counting up the count value is executed every 4 ms, and the random number is generated by extracting the count value at a lottery timing. The count value of the random number for winning / failing lottery is counted from the initial value and returns to the initial value when reaching 65535.

  Since the initial value of the random number for winning / failing lottery is also periodically or irregularly updated with another random number, the initial value becomes different every time the count value returns to the initial value. The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, the determination result of winning or losing is associated with the winning / losing lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a success / failure table for determination of success / failure based on a normal probability in normal times, and refers to a success / failure table in which the winning probability is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure tables and determines whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol that shows the determination result by the success / failure lottery means 112 in an effect manner is variably displayed on the effect display device 60.

  The symbol variation determining means 114 determines whether or not the special symbol stop pattern and the variation pattern to be displayed on the special symbol display device 61 and the decoration symbol variation pattern to be displayed on the effect display device 60 are determined to be a lottery unit. It is determined according to the result of the lottery 112 and a predetermined lottery value. Further, the symbol variation determining means 114 determines the stop symbol of the normal symbol to be displayed on the normal symbol display device 59 by lottery. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol variation determining means 114 holds a symbol range table to be referred to in order to determine a special symbol or a normal symbol stop symbol, or a pattern determination table to be referred to in order to determine a variation pattern. The symbol variation determining unit 114 sends data indicating the determined stop symbol and variation pattern to the main display control unit 118 and the effect determining unit 132.

  The symbol variation determining means 114 acquires a symbol determination lottery value for determining a special symbol, and determines a stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value. The symbol variation determining unit 114 determines to select one of a plurality of variation patterns based on the determination result of the success / failure determination unit 112, the lottery value for pattern, and the pattern determination table. The symbol variation determining means 114 stores a plurality of variation pattern types in which the variation mode from the variation start to the variation stop when the special symbol is variably displayed is defined in the pattern determination table. Multiple types of variation patterns have various variation times. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation display time elapses. The symbol variation determination means 114 refers to separate pattern determination tables for cases where the determination result is a win or fail, and refers to separate pattern determination tables for cases where time is short or not. The symbol variation determining means 114 selects a variation pattern associated with the pattern lottery value in the pattern determination table to be referred to.

  The pattern lottery value extracted by the symbol variation determining means 114 is a random number obtained by extracting a count value of a counter that counts up from an initial value of a predetermined pattern lottery random number at the lottery timing. The pattern lottery random number is also updated to count up every 4 ms. The update timing of the count value is set to be the same timing as the timing of counting the variation time of the variation pattern, and the acquisition timing of the random number for pattern lottery is set at the start of symbol variation based on the variation pattern. An upper limit is set for the random number for pattern lottery, and when the upper limit is reached, the initial value is always returned to zero.

  When the game ball passes through the operation port 68, the symbol variation determining means 114 acquires a lottery random number for determining a normal symbol, and determines a stop symbol of the normal symbol according to the lottery random number. When the stop symbol of the normal symbol is a specific symbol, the opening / closing control means 124 expands the normal electric accessory at the start port 62 for a predetermined time.

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4.

  The main display control means 118 causes the special symbol display device 61 to display the result of the lottery by the success / failure lottery means 112 as a special symbol variation display according to the variation pattern determined by the symbol variation determination unit 114. The main display control means 118 transmits the change start command and the change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol, so that the main display control means 118 and the effect display are displayed. The fluctuation display by the control means 134 is synchronized and interlocked. The main display control means 118 displays the normal symbol variation on the normal symbol display device 59.

  The special game control means 120 controls the execution process of the special game when the result of the lottery determination by the success / failure lottery means 112 is a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously continued a plurality of times, and is constituted by one or a plurality of unit games with one opening / closing as a unit. The unit game is repeated up to 15 times, for example, and the big prize opening 66 is opened for about 30 seconds in one unit game. If the number of continuations of the unit game has not reached the upper limit number, the special game control means 120 starts the next unit game after the end of the current unit game. When the upper limit number of unit games is exhausted, the special game is terminated.

  In the present embodiment, an effect based on a specific variation pattern (hereinafter also referred to as “specific effect”) is displayed in a plurality of initial symbol variations after the end of the special game. For this reason, at the end of the special game, a special interrupt process including a special game end process executed by the special game control means 120 and a change pattern selection process executed by the symbol fluctuation determining means 114 is executed. This specific performance is inherited in the original normal game after the end of the special game.

  The specific game execution means 122 executes control for shifting the game state from the normal state to the specific game state, and control for returning the specific game state to the normal state. The specific game in the present embodiment has a probability change in which the winning probability of the winning / failing lottery is switched from a normal probability state to a high probability state, and a short time in which the symbol variation time is switched from a normal time to a short time.

  The specific game executing means 122 shifts the gaming state after the special game to the probability changing state when the winning / failing lottery value is a value to be shifted to the probability changing state. The probability variation state is continued until the next jackpot occurs, and during that time, the probability of the hit determination by the hit / fail lottery means 112 is maintained at a high value. In addition, the specific game executing means 122 shifts the game state to the time-shortened state after the special game regardless of the winning lottery value. The short time is continued until the number of changes in the special symbol after the special game reaches a predetermined number, for example, 100 times.

  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol is stopped at a specific symbol, the opening / closing control unit 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.

  The pattern storage unit 130 holds a plurality of variation pattern data in which a variation process from variation start to stop in variation display is defined as a variation pattern of the effect image including the decorative design. The fluctuation pattern displays a pattern for displaying a normal out symbol, a pattern for displaying a symbol out of reach after reaching a big win if one more symbols are aligned, and a jackpot symbol through a reach state. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. For example, reach reach patterns such as normal reach that does not involve development in production such as background switching, and super reach that enhances reliability for jackpots, including development in production by producing a story with a specific character, etc. . Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. In accordance with the determination by the symbol variation determining unit 114, the effect determining unit 132 selects a variation pattern corresponding to the variation pattern of the special symbol, that is, a variation pattern of the effect image having the same variation time.

  The effect determining means 132 determines the combination of the stop symbols of the decorative symbols and the arrangement thereof according to the result of the lottery by the success / failure lottery means 112, according to the stop symbol of the special symbol and the variation pattern of the special symbol. The effect determining means 132 holds a symbol range table to be referred to in order to determine the stop symbol of the decorative symbol.

  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the determination result by the success / failure lottery means 112 indicates a shift to a special game, three symbols such as “777” and “111” are arranged. A combination is selected. In this case, it is preferable that the same numbers as the special symbols are selected as the numbers arranged as the decorative symbols. For example, when the special symbol is “3”, the decorative symbol is “333”. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the special game, a combination that does not have three symbols such as “312” and “946” is selected. However, if the determination result is that the game does not shift to a special game, and a variation pattern of a special symbol indicating a loss with reach is selected, only one such as “191” or “727” is selected. Select a combination that does not have the same pattern. The effect determining unit 132 sends information about the stop symbol of the decorative symbol and the variation pattern of the effect image to the effect display control unit 134.

  The effect display control means 134 displays the effect image on the effect display device 60 in accordance with the selected variation pattern data as a result of the success / failure lottery by the success / failure lottery means 112. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.

  In accordance with the instruction received from the effect display control means 134, the accessory control means 136 causes the movable accessory 140 to act in an effect manner in accordance with the effect contents in the effect display device 60 and the blinking process of the game effect lamp 90.

  Here, each process included in each component included in the main board 102, for example, the lottery means 112 or the symbol variation determining means 114 is executed by a CPU (central processing unit) included in the main board 102. The CPU executes a main loop process to be repeatedly processed and an interrupt process to be processed in priority to the main loop process by being interrupted as a temporary execution instruction. The main loop process is, for example, a process related to overall control of a normal game or a special game, and can include a regular random number update process. Interrupt processing is processing such as lottery value acquisition and prize ball processing that is performed each time a ball enters the entrance, for example, random number update processing, random number initialization processing, lottery value extraction processing, etc. Included.

  In conjunction with a specific game control process, a specific fluctuation pattern (hereinafter referred to as “specific fluctuation pattern”) having contents related to the game control process is forcibly selected as a developer's intention to display a symbol fluctuation display. If you want to do this, design as follows. For example, when the special game end process is executed as a specific game control process, it is desired to display the symbol variation according to the specific variation pattern as the first variation pattern of the newly started normal game. The specific variation pattern in the present embodiment is a normal game in which both a short time and a probability change occur after the end of the special game, or a normal game in which only the short time occurs, and the player's expectation over multiple symbol variations. It is a variation pattern with stunning production contents. In this case, a process for initializing the count value of the random number for pattern lottery and a process for extracting the lottery value for pattern for the interrupt process including the end process of the special game and the interrupt process for several times in the normal game thereafter The CPU is executed including

  The count value update process is not sandwiched between the count value initialization process and the extraction process, and the pattern lottery value extracted in the initial predetermined period after the special game end process is the upper limit of the random number for pattern lottery. The initial value of the random number for pattern lottery is always set in relation to the value and the variation time of the variation pattern. This “predetermined period” can be set, for example, as the number of symbol fluctuations (also referred to as “set number”) after the special game end process. In this case, the predetermined period corresponds to a variation time for a plurality of symbol variations by the specific variation pattern, and corresponds to a display time of the effect pattern displayed within the variation time.

  Then, if the specific variation pattern is associated with the same pattern lottery value as the initial value of the pattern lottery random number in the pattern determination table, the specific variation pattern is always selected immediately after the end of the special game. As described above, if the specific variation pattern is associated with the same pattern lottery value as the initial value of the pattern lottery random number in the pattern determination table, the specific variation pattern can be continuously selected at a specific timing. Further, since it is not necessary to hold a dedicated pattern determination table only for such a special selection, it is possible to avoid an unnecessary increase in the amount of data.

  It should be noted that a new variation pattern is not immediately selected if the winning / raising lottery value is not already held at the time when the special game ends. Therefore, a special game end process in which the pattern lottery value initialization process and the extraction process are included in one interrupt process is executed on the condition that the special game is held at the end. . However, while there is sufficient time for a special game period, the winning / failing lottery values are not consumed during the special gaming period, so there is a possibility that multiple winning / losing lottery values are usually held at the end of the special game. Is expensive. For this reason, if the set number of times is appropriately adjusted, the symbol variation display by the specific variation pattern in the symbol variation in the predetermined period after the end of the special game can be substantially substantially realized.

  In addition, since the pattern determination table that is referred to when selecting a specific variation pattern is also a table that is always referred to at other times, the pattern lottery value coincides with the initial value of the pattern lottery random number. There is a possibility that the specific variation pattern may be selected in the case of the failure. Therefore, at the time of accidental selection, the special symbol is displayed in a variable manner with the variation time of the specific variation pattern, and the effect determining means 132 performs a process of replacing it with another pattern having the same variation time as the variation pattern of the decorative symbol. Also good. Whether it is such an accidental selection or not may be determined, for example, by referring to the number of symbol variations after the end of the special game. In that case, if the symbol variation is within the set number of times after the end of the special game, it will be determined that the symbol variation is due to the specific variation pattern at the timing intended by the developer, while the symbol variation exceeding the set number of times after the end of the special game. If so, it turns out to be an accidental choice.

  In addition, when the winning / losing lottery value is not held at the time when the special game is ended, for example, the specific variation pattern may be selected from the time when the winning / losing lottery value is subsequently held. In addition, if the number of pending winning lottery values at the time of completion of the special game is less than the set number of times, even if the specific performance based on the specific variation pattern is started, it can be interrupted and the player can feel uncomfortable There is sex. Even if the winning / losing lottery value is withheld thereafter, the player's sense of expectation may be lost due to the extension of the specific performance. For this reason, even when the number of pending winning lottery values at the end of the special game is less than the set number of times, the special symbols are displayed in a variable manner with the variation time of the specific variation pattern as in the case of the accidental selection. In addition, as the decorative pattern variation pattern, the effect determining means 132 may perform a process of replacing it with another pattern having the same variation time. Moreover, since it can be said that it is not "the initial symbol fluctuation after the end of the special game" except during the time saving, it may be determined that it is an accidental selection by not being in the time saving.

FIG. 4 is a diagram schematically showing an example of effect contents according to a specific variation pattern to be displayed as an initial symbol variation after the end of the special game.
In this embodiment, at the beginning of the special game, the player is informed whether the normal game is a normal game with both time reduction and probability change, or whether it is a normal game with only time reduction without probability change. The specific effect to be displayed is displayed. As a notification method, the result is not simply displayed at the first symbol variation after the end of the special game, but rather is determined over a relatively long time over a plurality of symbol variations. By displaying such stunning contents, the player's expectation is informed and informed. In this embodiment, a series of effects are performed over a plurality of symbol variations, but similar effects may be repeated over a plurality of symbol variations.

  In the example of this figure, while the variable display of the decorative design 190 is displayed small in the lower right corner of the display screen 200, the first object 202 and the second object 204 are competing using most of the area of the display screen 200. The player's expectation is expressed by displaying such a video. Both the first object 202 and the second object 204 are images of a racing car, and display a state of running while competing for rank toward the goal. For example, if it is suggested that a normal game with certainty will be started when the first object 202 finishes first, the player pays attention to the production contents while expecting the first object 202 to finish first. Will be. If the first object 202 makes a goal first after such an effect of encouraging the expectation, a result display showing that the game is a normal game with both time reduction and probability change is made, and the second object 204 takes the goal first. If it does so, the result display which shows that it is a normal game with only a short time will be made.

In the present embodiment, this specific effect is intentionally displayed over the period of three symbol variations after the end of the special game. Specifically, the first stage effect in which both objects start in the first symbol change after the end of the special game is displayed, and in the subsequent second symbol change, both objects overtake each other and compete for the ranking. An effect is displayed, and a third-stage effect in which any object finishes first in the subsequent third symbol variation is displayed. The fluctuation times of the three symbol fluctuations are set to be equal. That is, the symbol variation determining unit 114 selects a specific variation pattern with a fixed variation time as the symbol variation for three times after the special game ends, and sends information (pattern number) indicating the variation pattern to the effect determining unit 132. Send to. When receiving the information that the specific variation pattern has been selected, the effect determining means 132 determines the number of times the information is received after the special game is finished, and indicates what stage of the specific effect is to be displayed. The production pattern corresponding to each stage of the specific production is sequentially selected. That is, only the variation time corresponding to the specific variation pattern is determined on the main substrate 102 side. Then, the content (stage) of the specific effect displayed at the variation time of the specific variation pattern is determined on the sub-board 104 side.
In the modification, the main board 102 may determine the content of the specific variation pattern. In other words, as the specific variation pattern, the first specific variation pattern with the first stage effect of the specific effect, the second specific variation pattern with the second stage effect, and the third specific variation pattern with the third stage effect are set. Each specific variation pattern may be identified by a pattern number. Then, the symbol variation determining means 114 determines the number of symbol variations after the end of the special game, determines what stage of the specific effect should be displayed, and corresponds to the stage based on the determination result. The specific variation pattern may be determined and the pattern number may be sent to the effect determination means 132. The effect determining unit 132 may sequentially select effect patterns corresponding to the received pattern numbers. Needless to say, the number of symbol fluctuations as the display period of the specific effect is not limited to three, and can be appropriately changed.

FIG. 5 is a diagram illustrating a processing process of a main loop process and an interrupt process in a game execution process starting from activation of the pachinko gaming machine 10.
The power of the pachinko gaming machine 10 is turned on at t1, and the activation process is executed until t2. Processing interrupts are prohibited during the startup process. Although the startup process at the time of power-on is illustrated in this figure, the same process as the startup process is performed during the recovery process after power interruption, and interrupts are prohibited. The main loop process is executed from t2. In the main loop process, the count value for the success / failure lottery, its initial value, and the count value for the pattern lottery are updated every 4 ms, and other processes included in the main loop process are executed at other times.

  After t2, the presence / absence of an interrupt is monitored every 4ms, and the interrupt process is executed with priority over the main loop process from t3 when the interrupt occurred until t4 after 4ms. The interrupt is confirmed also at t4 after 4 ms from t3, and the interrupt processing is executed continuously from t4 to t5 after 4 ms. The main loop process is executed again from t5 when there is no interrupt, and the interrupt process is executed again from t6 when there was an interrupt. However, since the interrupt process started from t6 is completed at time t7 before 4 ms elapses, the main loop process is resumed from t7 without waiting for 4 ms elapses. As described above, while the main loop process is mainly executed, if there is an interrupt instruction, the interrupt instruction is executed at intervals of 4 ms, and the remaining time of the interrupt instruction is used for the main loop process. Since each interrupt instruction includes a lottery random number update process in principle, the update is maintained at intervals of 4 ms. Thereby, it is possible to prevent the same value from being output as the lottery value without updating the random number for lottery by the interruption process.

  FIG. 6 is a diagram illustrating the contents of the interrupt process including the special game end process in the present embodiment. In the example of this figure, the first process P1 to the ninth process P9 are sequentially processed within 4 ms from the start of the interrupt process to the end of the interrupt process. As the first process P1, the initial value of the random number for success / failure lottery is updated. The initial value of the random number for success / failure lottery is updated every 4 ms. When the count value of the random number for randomness for success / failure reaches the upper limit value, it is returned to the initial value of the random number for random determination for success / failure at that time. Each time the initial value is different. As the initial value of the random number for winning / failing lottery, a random value is extracted using another random number. The second process P2 is updated by counting up the count value of the random number for success / failure lottery.

  As the third process P3, a random number for pattern lottery is initialized. The initial value of the random number for pattern lottery is 0, for example, and the count value of the random number for pattern lottery is returned to 0 by initialization. However, as another modification, another predetermined value may be set as the initial value of the random number for pattern lottery. As a fourth process P4, a special game end process is executed. The special game ending process is, for example, a process for turning off a flag indicating that a special game is in progress or a process for turning on a flag indicating a short time or a certainty change. When the flag indicating that the special game is in progress is turned off, the normal game is started from that point.

  In the fifth process P5, the lottery value that has been put on hold is read out. However, the processing from P5 to P9 is not executed when the winning / losing lottery value is not reserved. As the sixth process P6, the success / failure determination process is executed. The success / failure determination process is determined based on whether the success / failure lottery value acquired in P5 is within a predetermined hit range. As the seventh process P7, the symbol variation determining means 114 extracts a pattern lottery value. The pattern lottery value extracted at P7 is the count value of the pattern lottery random number initialized at P3. Since there is no pattern lottery random number update process between P3 and P7, the pattern lottery is always performed in this embodiment. The initial value of the random number for use is “0”. As an eighth process P8, the symbol variation determining means 114 selects a variation pattern corresponding to the pattern lottery value extracted in P7.

  As the ninth process P9, the symbol variation determining means 114 determines a special symbol. In the example of this figure, for the sake of convenience, only the processing in the range necessary for explaining the contents of the present embodiment is given, and processing other than P1 to P9 may be included in the same interrupt processing. For example, the process for updating the random number for pattern lottery may be included in the interrupt process, but is not executed at least from the initialization of the random number for pattern lottery to the extraction process for the pattern lottery value. It can be included at any timing.

  By executing such an interrupt process after the special game is finished, a specific variation pattern is selected for a predetermined period thereafter, the details of which will be described later.

  Next, a mechanism in which the specific variation pattern with the specific effect described above is continuously selected after the special game in the present embodiment will be described. FIG. 7 is a data structure diagram of a pattern determination table used when determining the variation pattern of the special symbol. Actually, a wide variety of variation patterns subdivided from those shown in the figure are prepared, but for convenience of explanation, they are only conceptually shown here.

  This pattern determination table shows data to be referred to when the symbol variation determining means 114 determines the variation pattern of the special symbol. The symbol variation determining means 114 acquires a pattern determination lottery value from the range of “0 to 999” prior to displaying the variation of the special symbol. Based on the pattern determination lottery value and the result of the success / failure lottery by the success / failure lottery means 112, the variation time of the special symbol is determined. Each variation pattern is assigned a variation pattern number (not shown) for identifying the variation pattern.

  In the illustrated example, according to the range of the pattern determination lottery value, the variation time is 4.4 seconds, the variation pattern is accompanied by a specific effect, the variation time is 5 seconds, the variation pattern is not accompanied by a reach effect, and the variation time is 30 seconds. The variation pattern with the effect of normal reach and the variation pattern with the effect of super reach with a variation time of 60 seconds are set. The illustrated variation patterns with no reach effect, normal reach, and super reach are appropriately referred to as “normal variation patterns” in that they do not have a specific effect. A variation pattern with a longer variation time tends to be selected when the result of winning / failing lottery is a win than when it is out of place.

  When the pattern determination lottery values are “0”, “100”, “200”, the specific variation pattern is selected.

That is, in this embodiment, the pattern lottery random number “0-999” with the random number size set to 1000 is updated every 4 ms, and the pattern lottery random number reaches Np (999) which is the upper limit value. Each time, it is always returned to the initial value “0”. Then, any random number is acquired as a pattern determination lottery value at a predetermined extraction timing in the update process. Therefore, the time interval from when the random number for pattern lottery is returned to the initial value until it reaches the upper limit, that is, the cycle of the initialization timing (also referred to as “initialization cycle”) is 4 seconds. On the other hand, the random number for pattern lottery is initialized at the start of the first symbol variation after the end of the special game, and the pattern determination lottery value “0” is acquired at this initialization timing.
Here, since the variation time of the specific variation pattern is fixed to 4.4 seconds, it is 1100 when converted to the number of times of updating the random number for pattern lottery. Therefore, the next extraction timing of the pattern determination lottery value is 1100 counts from the initialization timing, that is, the initialization cycle + 100 counts, and “100” is acquired as the pattern determination lottery value. Similarly, the next extraction timing is further an initialization period + 100 counts, and “200” is acquired as the pattern determination lottery value. In other words, “0”, “100”, and “200” are sequentially acquired as the pattern determination lottery values after the special game ends, so that the specific variation pattern is continuously selected up to three symbol variations after the special game ends. Will come to be. As a result, a series of specific effects as described above can be displayed.

  FIG. 8 is a timing chart showing the relationship between the extraction timing of the pattern determination lottery value executed after the end of the special game and the initialization timing of the count value as the random number for pattern lottery. The horizontal axis of the figure represents the passage of time, and the vertical axis represents the count value. In the present embodiment, a counter for periodically counting up the random numbers for pattern lottery is set in a predetermined area on the RAM.

  In the illustrated example, at the time t1 when the special game ends, the counter is initialized and the count value is returned to 0, and at the same time, the pattern determination lottery value is extracted. For this reason, “0” is acquired as the pattern determination lottery value. As a result, the specific variation pattern corresponding to the pattern determination lottery value “0” is selected (see FIG. 7). Since this time t1 corresponds to the start time of the first symbol variation after the end of the special game, the display of the first stage of the specific effect is started. Since the count value reaches the upper limit value (Np = 999) at time t2 when 4 seconds have passed since then, the counter is initialized and the count value is returned to zero. The next pattern determination lottery value is extracted at time t3 when 4.4 seconds, which is the variation time T of the specific variation pattern, has elapsed from time t1. Note that the variation time T of the specific variation pattern includes a variation time T1 from when the special symbol variation is started to when it is stopped, and its stop display time (fixed display time) T2. At time t3, since 0.4 seconds have elapsed since the count-up was resumed at time t2, “100” is acquired as the pattern determination lottery value. As a result, the specific variation pattern corresponding to the pattern determination lottery value “100” is selected (see FIG. 7). However, since this time t3 corresponds to the start time of the second symbol variation after the end of the special game, the second stage display of the specific effect is started.

  Similarly, the next pattern determination lottery value “200” is extracted at time t4 when the variation time T of the specific variation pattern has elapsed from time t3, and the specific variation pattern corresponding to this is selected (see FIG. 7). However, since this time t4 corresponds to the start time of the third symbol variation after the end of the special game, the third stage display of the specific effect is started. At time t5 when the variation time T of the specific variation pattern has elapsed from time t4, the pattern determination lottery value “300” is extracted, but the specific variation pattern is not selected and the normal variation pattern is selected (FIG. 7). reference). That is, after time t5, since the correspondence between the variation time of the variation pattern and the extraction timing of the pattern determination lottery value is basically random, the specific variation pattern is prevented from being permanently selected, and the gaming state Can be eliminated.

FIG. 9 is a flowchart showing a basic operation process in the pachinko gaming machine.
As described above, the various processes in the pachinko gaming machine 10 are composed of a main loop process and a plurality of interrupt processes. However, in the flowcharts subsequent to this figure, they are not distinguished from each other and follow the flow of game control. Each process will be described. First, processing when a game ball has won the starting port 62, the general winning port 72, the big winning port 66, etc., or when the game ball has passed through the operation port 68, for example, setting processing of a winning ball, acquisition of a winning / failing lottery value Process, hold process of the lottery value (S10). If special game is in progress (Y in S12), special game control process is executed (S13), and if not in special game (N in S12) ), S13 is skipped. Subsequently, if the game is in a normal game (Y in S15), control processing for normal games such as determination of success / failure and symbol variation is executed (S16). If not in a normal game (N in S15), S16 is skipped. . Prize ball payout according to various winnings in the processing from S10 to S16 is processed (S18).

FIG. 10 is a flowchart showing in detail S13 in FIG.
First, if the big prize opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special prize opening 66 (S74). ). If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.

  If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 executes a special game end process (S86). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).

FIG. 11 is a flowchart showing in detail S86 in FIG.
First, the initial value of the random number for success / failure lottery is updated (S100), the count value of the random number for randomness for success / failure is updated by up-counting (S102), and the count value of the random number for lottery of pattern lottery is initialized (S104). As a special game ending process, a process for turning off a flag indicating that a special game is in progress and a flag indicating a time reduction or probability change are turned on (S106). The normal game starts from this point.

  On the condition that the winning / failing lottery value is held, the next processing after S110 is executed (Y of S108), and if the winning / failing lottery value is not held, S110 to S124 are skipped (S108). N). In the case of Y in S108, the success / failure lottery means 112 reads the success / failure lottery value (S110), and determines the success / failure (S112). The symbol variation determining means 114 extracts a pattern lottery value (S114), determines a variation pattern (S116), and determines a special symbol (S118). As described above, in the figure, the processes from S100 to S118 are mainly executed in the main board 102, and these processes are executed in one interrupt process as shown in FIG. The variation pattern and the special symbol determined in S116 and S118 are sent to the main display control unit 118 and the effect determination unit 132, and the effect determination unit 132 determines the decoration symbol (S120), and selects the variation pattern of the decoration symbol. (S122), the main display control means 118 and the effect display control means 134 start the variable display of symbols (S124). In the example of this figure, the special game end process (S106) is executed after the pattern random number initialization process (S104). However, as a modification, it may be executed in the reverse order. In addition, another process may be executed between the pattern random number initialization process (S106) and the pattern random number extraction process (S114), but the other process executed in this case is at least a pattern random number. It must be a process other than the update process.

  FIG. 12 is a flowchart showing in detail the normal game control process of S16 in FIG. In the normal game control process, if the winning / failing lottery value is held (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery unit 112 and the symbol variation determining unit 114 are An appropriate / bad determination process, a symbol determination process, and a pattern determination process are executed (S34). In accordance with the determination result, the main display control means 118 starts changing display, transmits a change start command to the effect display control means 134, and the effect display control means 134 that receives the command displays the effect image according to the change pattern data. The fluctuation display is started (S36). If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. For example, as shown in FIG. 9, when the special game end process has been executed and the symbol variation has already started (S124), Y in S32 is followed. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. .

  FIG. 13 is a flowchart showing in detail the success / failure determination process of S34 in FIG. First, the success / failure lottery means 112 reads the success / failure lottery value (S42), and determines the success / failure based on the success / failure lottery value (S44). The symbol variation determining means 114 determines a stop symbol of the special symbol based on the determination result (S46), and determines the variation pattern (S48). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S50), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S52). At this time, if the symbol variation is within the third time after the end of the special game, the variation pattern with the specific effect described above is selected, and if it is the fourth or subsequent symbol variation, the normal variation pattern is selected.

  As described above, in the present embodiment, the variation time of the specific variation pattern, the initialization timing of the random number for pattern lottery, and the extraction timing of the pattern lottery value are based on the end timing of the special game. It is set to have a regular correspondence so that the specific variation pattern is extracted continuously. For this reason, the specific variation pattern is selected at a periodic timing in accordance with the initialization timing of the random numbers for pattern lottery. As a result, the specific variation pattern can be continuously selected without changing the variation pattern. As a result, it is not necessary to prepare a special pattern determination table only for selecting a specific variation pattern, and a useless increase in data amount can be avoided.

(Second embodiment)
This embodiment is different from the first embodiment in that a plurality of pattern lottery counters are set and the timing for selecting a specific variation pattern is determined based on the plurality of random values. Hereinafter, differences from the first embodiment will be described, and description of similar configurations and processing portions will be omitted.

  FIG. 14 is a data structure diagram of a pattern determination table used when determining the variation pattern of the special symbol in the second embodiment. Actually, a wide variety of variation patterns subdivided from those shown in the figure are prepared, but for convenience of explanation, they are only conceptually shown here. In addition, the “normal fluctuation pattern” shown in the figure includes the fluctuation patterns accompanied by each of the effects of no reach, normal reach, and super reach shown in FIG. Furthermore, in practice, the relationship between the pattern determination lottery value and the variation pattern (variation time) is set to be different according to the result of the success / failure lottery, but detailed description thereof is omitted here.

  This pattern determination table shows data to be referred to when the symbol variation determining means 114 determines the variation pattern of the special symbol. A first counter, a second counter, and a third counter are set in predetermined areas on the RAM, respectively, and random numbers 1, 2, and 3 are up-counted as pattern lottery random numbers, respectively. Each counter update period is set to 4 ms. The size of random number 1 is set to 250, the size of random number 2 is set to 249, and the size of random number 3 is set to 248. When the combination of these three random numbers becomes a predetermined combination, a specific variation pattern is selected. . The three random numbers are acquired before each random number is updated. That is, the process of updating three random numbers is sequentially performed as an interrupt process, but the update of each random number is not executed until the process of extracting the random number is performed.

  As shown in the figure, the specific variation pattern is selected as one reference condition that the random number 1 is initialized. That is, the random number 1 functions as a reference count value, and the first counter that counts the random number 1 functions as a reference counter. On the other hand, the random numbers 2 and 3 are referred to in order to limit the selection timing so that the specific variation pattern is selected at the specific initialization timing of the random number 1. That is, the random number 2 functions as the first reference count value, and the second counter that counts the random number 2 functions as the first reference counter. The random number 3 functions as a second reference count value, and a third counter that counts the random number 3 functions as a second reference counter.

  The symbol variation determining means 114 acquires the first lottery value from the range of “0 to 249” of the random number 1 as the pattern determination lottery value and displays the range of “0 to 248” of the random number 2 before displaying the variation of the special symbol. The second lottery value is acquired from the range, and the third lottery value is acquired from the range of “0 to 247” of the random number 3. Based on the pattern determination lottery value and the result of the success / failure lottery by the success / failure lottery means 112, the variation time of the special symbol is determined. Each variation pattern is assigned a variation pattern number (not shown) for identifying the variation pattern.

  In the illustrated example, when all the counters are initialized and all of the random numbers 1 to 3 are “0”, the specific variation pattern is selected. The specific variation pattern is selected when the random number 1 is “0”, the random number 2 is a multiple of 4, and the random number 3 is a multiple of 8. In this embodiment, the random number 1 is initialized so that the specific variation pattern can be continuously selected, and the difference between the random number 1 and the random number 2 is four times the difference between the upper limit values of both random numbers “1”. Every time a certain “4” is updated and “8”, which is four times the difference between the random numbers 1 and 3, which is the difference between the upper limits of the two random numbers, is updated, the pattern lottery value is extracted. Interrupt processing is executed. However, in this embodiment, the specific variation pattern is selected only in a period (N ≦ 4) where the number of symbol variations N after the end of the special game is four times, and for the fifth and subsequent symbol variations (N> 4). The combination of pattern lottery random numbers is associated with the specific variation pattern so that the normal variation pattern is selected.

  FIG. 15 is a timing chart showing the relationship between the extraction timing of the pattern determination lottery value executed after the end of the special game and the initialization timing of the count value as the random number for pattern lottery. In the figure, the vertical axis shows the count value of the first counter (random number 1), the count value of the second counter (random number 2), and the count value of the third counter (random number 3) from the top. The horizontal axis of the figure represents the passage of time.

  In the illustrated example, at time t21 when the special game ends, all the counters are initialized and the count value is returned to 0, and at the same time, the pattern determination lottery value is extracted. Therefore, “0, 0, 0” is acquired as a combination of the first lottery value, the second lottery value, and the third lottery value as the pattern determination lottery value. As a result, the specific variation pattern corresponding to the pattern determination lottery value “0, 0, 0” is selected (see FIG. 14). Since this time t21 corresponds to the start time of the first symbol variation after the end of the special game, the variation pattern corresponding to the first stage of the specific effect is selected from the specific variation patterns. The variation time T of this specific variation pattern is set to 4 seconds, which is four times the initialization period T1 (1s) of the random number 1. The variation time T of the specific variation pattern also includes a variation time of a special symbol (not shown) and a fixed display time (stop display time).

  Then, at time t22 when the variation time (4 seconds) of the specific variation pattern has elapsed, the symbol variation stops, and a combination “N1, N2, N3” of the first lottery value, the second lottery value, and the third lottery value is obtained. “0, 4, 8” has been acquired. As a result, the specific variation pattern corresponding to the pattern determination lottery value “0, 4, 8” is continuously selected. The difference between the lottery values is that the upper limit value Np1 of the random number 1, the upper limit value Np2 of the random number 2, and the upper limit value Np3 of the random number 3 are different (Np1> Np2> Np3). This is caused by the fact that the initialization cycle T2 of T1, random number 2 and the initialization cycle T3 of random number 3 are different (T1> T2> T3).

  Since this time t22 corresponds to the start time of the second symbol variation after the end of the special game, the variation pattern corresponding to the second stage of the specific effect is selected from the specific variation patterns. Similarly, “0, 8, 16” is acquired as a combination of the first lottery value, the second lottery value, and the third lottery value at the timing when the second symbol variation ends, and the third symbol variation ends. At the same timing, “0, 12, 24” is acquired as a combination of the first lottery value, the second lottery value, and the third lottery value. As a result, the specific variation pattern is continuously selected for the third and fourth symbol variations. For the fifth symbol variation, the variation pattern having a variation time different from 4 seconds is selected as a selection target to prevent the selection of the specific variation pattern, thereby eliminating the bias of the gaming state.

  As described above, in this embodiment, the number of updates of the reference count value until the reference counter is initialized is set different from the number of updates of the reference count value until the reference counter is initialized. ing. Then, paying attention to the fact that every time the standard counter is initialized, the difference between the count values of the standard counter and the reference counter changes regularly, and whenever the difference updates the specific value, the lottery value for pattern To extract. Thereby, the specific variation pattern can be extracted at a periodic timing at which the reference counter is initialized a plurality of times. If the count upper limit value of the reference counter and the count upper limit value of the reference counter are appropriately set and changed, the extraction timing of the specific variation pattern can be arbitrarily set by the combination. As a result, the degree of freedom in setting the variation time of the specific variation pattern is increased, and it is easy to design an effect to be displayed corresponding to the specific variation pattern.

(Third embodiment)
This embodiment is different from the first embodiment in that a specific variation pattern is selected every time a predetermined number of pattern lottery random numbers are updated within the initialization period. Hereinafter, differences from the first embodiment will be described, and description of similar configurations and processing portions will be omitted.
FIG. 16 is a data structure diagram of a pattern determination table used for determining a special symbol variation pattern in the third embodiment. Actually, a more detailed variation pattern than that shown in the figure is prepared, but for convenience of explanation, it is only conceptually shown here.

  As shown in the figure, in this embodiment, the size (upper limit value) of the random number for pattern lottery is set to 1000, and the specific variation pattern may be selected every time the count value in the counter is updated to 300. Is set to The count value is updated every 8 ms. On the other hand, since the variation time of the specific variation pattern is set to 2.4 seconds corresponding to the update of the 300 random numbers, if the specific variation pattern is selected at each extraction timing of the random numbers for pattern lottery, the specific variation pattern A specific effect corresponding to the pattern is continuously displayed.

  In this embodiment, the specific variation pattern is always selected at the initialization timing of the random numbers for pattern lottery after the end of the special game. However, when the count value becomes 300, 600, 900 thereafter, the specific variation pattern and normal The variation pattern is selected by a lottery with a probability of 50%. In the modification, for example, the selection probability of the specific variation pattern may be set as high as 80%. As described above, it is possible to increase the player's expectation by giving the uncertainty to the selection of the specific variation pattern.

(Fourth embodiment)
This embodiment is different from the first embodiment in that a specific variation pattern is selected for each initialization period of pattern lottery random numbers. Hereinafter, differences from the first embodiment will be described, and description of similar configurations and processing portions will be omitted.
FIG. 17 is a data structure diagram of a pattern determination table used when determining a variation pattern of special symbols in the fourth embodiment. Actually, a wide variety of variation patterns subdivided from those shown in the figure are prepared. However, for convenience of explanation, these are only conceptually shown here.
As shown in the figure, when the pattern determination lottery value is “0”, either the specific variation pattern or the normal variation pattern is selected. In this embodiment, in a period (N ≦ 3) in which the number of symbol variations N after the end of the special game is three (N ≦ 3), a specific variation pattern with a variation time of 4 seconds is selected, and symbol variations after the fourth time (N> 3). ), A normal fluctuation pattern having a fluctuation time of 5 seconds is selected.

  That is, in this embodiment, the random number for pattern lottery “0 to 999” in which the random number size (upper limit value Np) is set to 1000 is updated every 4 ms, and any random number is obtained at a predetermined extraction timing. As a pattern determination lottery value. Therefore, the time interval from when the random number for pattern lottery is returned to the initial value until the upper limit is reached, that is, the cycle of the initialization timing is 4 s. On the other hand, the random number for pattern lottery is initialized at the start of the first symbol variation after the end of the special game. For this reason, the initialization time interval of the random numbers for pattern lottery coincides with the variation time of the specific variation pattern. By using this match, a specific variation pattern can be selected continuously a plurality of times.

  FIG. 18 is a timing chart showing the relationship between the extraction timing of the pattern determination lottery value executed after the end of the special game and the initialization timing of the count value as the random number for pattern lottery. The horizontal axis of the figure represents the passage of time, and the vertical axis represents the count value. In the present embodiment, a counter for periodically counting up the random numbers for pattern lottery is set in a predetermined area on the RAM.

  In the illustrated example, at time t41 when the special game ends, the counter is initialized and the count value is returned to 0, and at the same time, the pattern determination lottery value is extracted. For this reason, “0” is acquired as the pattern determination lottery value. As a result, the specific variation pattern corresponding to the pattern determination lottery value “0” is selected (see FIG. 17). Since this time t41 corresponds to the start time of the first symbol variation after the end of the special game, the first stage display of the specific effect is started. The variation time T of the specific variation pattern is equal to the time interval at which the pattern determination lottery value is initialized.

For this reason, the initialization timing of the next pattern determination lottery value coincides with the extraction timing of the pattern determination lottery value of the next variation at time t42. As a result, the specific variation pattern is selected even in the next variation. However, since this time t42 corresponds to the start time of the second symbol variation after the end of the special game, the second stage display of the specific effect in the specific variation pattern is started. Similarly, at time t43, the initialization timing of the pattern determination lottery value matches the extraction timing of the pattern determination lottery value, and the specific variation pattern is selected. However, since this time t43 corresponds to the start time of the third symbol variation after the end of the special game, the third stage display of the specific effect in the specific variation pattern is started. On the other hand, at time t44, in order to correspond to the fourth symbol variation after the end of the special game (N> 3), the specific variation pattern is excluded from the selection target, and the normal variation pattern without reach without the specific performance is selected. The Since the fluctuation pattern without reach has a fluctuation time of 5 seconds, the initialization timing of the pattern determination lottery value and the extraction timing of the pattern determination lottery value are shifted thereafter. That is, by shifting the timing once in this way, it is possible to prevent the variation pattern corresponding to the pattern determination lottery value “0” from being permanently selected, and to eliminate the bias of the gaming state.
In this embodiment, the example of restricting the selection of the specific variation pattern by the number N of symbol variations after the end of the special game has been shown. However, for example, the reservation as the success / failure lottery value without restricting the selection of the specific variation pattern. As long as there is a sphere, the specific variation pattern may be continuously selected.

  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are within the scope of the present invention. is there. Hereinafter, such modifications will be described.

(First modification)
In the said Example, the example which selects the specific fluctuation pattern with a specific production in the predetermined period after the end of a special game was shown irrespective of the result of a success / failure lottery. In the modification, for example, the specific variation pattern may be selected only when the result of the lottery determination is out of place. If the result of the lottery is a win, the game shifts to a special game after the end of the change, so that it is considered that the existence significance of the effect asking whether or not the specific effect is being changed as in the same embodiment will fade. Because it is. Alternatively, when the result of the lottery is a win, the production pattern may be set so that a specific production having a content different from that of the embodiment corresponds. For example, a special effect such as a so-called full rotation reach that rotates in a state where three symbols of the decorative symbol 190 are aligned may be associated.

(Second modification)
In the fourth embodiment, the example in which the specific variation pattern is continuously selected after the special game is finished by matching the initialization timing of the random numbers for pattern lottery and the extraction timing of the pattern determination lottery value is shown. In the modification, the initialization timing and the extraction timing may be periodically shifted. For example, the time interval of the initialization timing may be set large so that the time interval of the extraction timing is an integral multiple of the time intervals of the extraction timing. In that case, if the specific variation pattern is associated with the pattern determination lottery value “0” as in the same embodiment, the specific variation pattern can be selected regularly every plurality of symbol variations. Thereby, it is possible to provide an opportunity to select another normal variation pattern while the specific variation pattern is selected. For this reason, the necessity of restricting the period during which the specific variation pattern is selected by the number of variations after the end of the special game as in the same embodiment is reduced. Or, conversely, the time interval of the extraction timing may be set large so as to be an integral multiple thereof so that the time interval of the initialization timing is included a plurality of times. In this case, if the specific variation pattern is associated with the pattern determination lottery value “0” as in the embodiment, it is easy to set a variation pattern having a long variation time as the specific variation pattern.

(Third Modification)
In the first embodiment, as shown in FIG. 9, the order of executing the special game control process (S13) first and the normal game control process (S16) later as necessary is described. In the modification, contrary to the example of FIG. 9, the normal game control process may be executed first, and the special game control process may be executed later as necessary. Even if the processing order is changed in this way, the same effect as that of the first embodiment is provided as long as the initialization timing of the random numbers for pattern lottery and the extraction timing of the lottery values for pattern are associated with each other in the interrupt processing after the special game ends Is obtained.

(Fourth modification)
In each of the above-described embodiments, the present invention has been described by taking a so-called first type pachinko gaming machine as an example. In this modification, the present invention is realized in a model in which a plurality of game characteristics are combined, for example, a model in which a plurality of first type pachinko gaming machines are combined. In that case, the following special effects can be produced also in special game playability. In other words, a plurality of start winning openings corresponding to the start opening 62 in the above embodiment are provided, and the first game and the second game resulting from winning at each start winning opening are executed in series or mutually exclusive. To do. Therefore, if the first start winning opening is won, the first special symbol and the first decorative symbol are variably displayed as the first game. Further, if a winning is made at the second start winning opening, the second special symbol and the second decorative symbol are variably displayed as the second game. While the first special symbol and the first decorative symbol are variably displayed, the variable display of the second special symbol and the second decorative symbol is not started, and the second special symbol and the second decorative symbol are not displayed. While the variable display is displayed, the variable display of the first special symbol and the first decorative symbol is not started. However, when the winning / losing lottery value is held in both the first game and the second game, the symbol variation in the second game is preferentially started.

  The first game and the second game may be a small win in addition to the case where the symbol stop mode and the lottery result are a big win. If the jackpot is reached, the first special game is executed in which the big winning opening 66 is opened as in the above embodiment. If it is a small hit, the second big prize opening having a blade structure like the so-called second type pachinko game machine is opened, and a game ball is placed in a specific area provided in the second big prize opening. When passing, the second special game is continuously executed. There is a difference between the first game and the second game, such as 1/200 in the first game and 199/200 in the second game. This means that a small hit does not occur easily in the first game, whereas a small hit occurs almost certainly in the second game every time. Therefore, it is easier for the player who is aiming for the second game than the first game to acquire the second special game, and the player is likely to be profitable.

  The second start winning opening is provided with an ordinary electric accessory as an expansion mechanism, like the start opening 62 of the above embodiment, and has a structure in which a winning can be made only in the expanded state. The start winning opening does not normally have an electric accessory. In addition, the ordinary electric accessory at the second start winning opening has a momentary expansion time so that almost no entry can be expected at times other than a short time, so that the expansion can be expected only enough during the short time. The opening time is lengthened. Moreover, the fluctuation time of the normal symbol fluctuation | variation which becomes an opportunity of expansion is shortened compared with those other than time reduction during time reduction. For this reason, it is almost impossible to win the second start winning opening until the jackpot is generated and the time shifts to short time, but it can be expected to win one after another during the short time. In the sense of generating the second special game, it is more convenient for the player to aim for the second game than the first game. I can't expect it. Therefore, at the time when the first special game, which is a so-called “first win”, that occurs at times other than during the time saving is completed and the time saving is started, the winning lottery value resulting from winning in the second start winning opening There is a high possibility that the suspension of is 0. On the other hand, during the first special game, there is a high possibility that the winning lottery value hold due to winning in the first start winning opening has reached the upper limit. In this case, the symbol variation of the first game whose variation time is shortened immediately after the shift to the short time is started, and the symbol variation of the first game starts one after another until winning the second start winning opening. There is a risk of being. The fact that the symbol variation is digested one after another means that it will be exhausted wastefully for a short period of time, so the player wants to win the second starting winning prize as soon as possible.

  Therefore, in this modified example, a specific variation pattern having a relatively long variation time is intentionally selected as a plurality of initial symbol variations after the end of the special game, and the second start winning opening is awarded within the variation time. To make it easy. The method for selecting the specific variation pattern is common to the above-described embodiment. If it is possible to successfully win the second start winning opening within the variation time according to the specific variation pattern, the number of symbol variations in the first game can be minimized. In this way, a situation that is preferable for the player can be intentionally generated by intentionally selecting the specific variation pattern. The variation time of the specific variation pattern in this modification is at least a variation time longer than the shortened deviation variation time, and preferably has a variation time equal to or greater than the maximum variation time of the normal symbol. The longer it is, the more the number of holds due to entering the second start winning opening can be increased, which is advantageous for the player.

  A game in which it is desirable for the player to fully understand the specifications of the complex gameability and the probability of winning / failing lottery, etc., which have a slightly more complicated part than the normal type 1 pachinko machine as in this modification In the type of sex, a specific variation pattern may be selected such that an effect explaining such game nature to the player is displayed.

(5th modification)
In each of the above-described embodiments, an example is shown in which the special game end is set as the specific timing, and the specific variation pattern is selected from the specific timing. In a modified example, for example, a specific variation pattern may be selected by setting a timing at which a so-called small hit as a result of the winning / failing lottery occurs as a specific timing. Alternatively, the operation timing of the special winning opening and the timing of some special effect control processing may be set as the specific timing. In this way, by setting the specific timing that triggers the selection of the specific variation pattern as appropriate, the specific effect with a low appearance frequency can be shown only in a certain gaming state, and the specific effect can be performed at the timing intended by the developer. Can be displayed.
