Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Conventionally, as a kind of gaming machine, a pachinko machine provided with a special symbol display device for variably displaying a plurality of types of symbols in a predetermined arrangement is known.

  In this type of pachinko machine, according to the display pattern (stop pattern) at the time of variable display stop on the display device, after passing through the reach state, it becomes a “special gaming state” that becomes advantageous to the player, after passing through the reach state An “out-going reach state” that does not become a special gaming state, or an “out-going state” that does not go through a reach state and does not become a special gaming state is generated. The stop symbols include a special game symbol (a jackpot symbol) for generating a special game state, a release reach symbol for generating a release reach, and a release symbol for generating a release state.

  In the pachinko machine as described above, the game situation that changes in accordance with the player's operation satisfies a predetermined condition (for example, a game ball wins an operating slot, etc.). The change display of is started. Also, a stop symbol corresponding to the game situation is selected from the special game symbol, the missed reach symbol, and the missed symbol, and the variable display is stopped at the selected stop symbol. And when it stops at a jackpot symbol, it is switched so that a special variation prize-winning device will be in a state advantageous to the player (a jackpot state). More specifically, the player can acquire a large amount of prize balls by opening the big prize opening or the like.

  Incidentally, in recent years, in this type of pachinko machine, auxiliary variable display control (for example, 7-segment display control) is performed by a normal symbol display device based on the passage of a normal symbol start port (or gate) provided separately. When the display result is in a predetermined stop state determined in advance (for example, when it is stopped at “7”), the normal variable winning device that also serves as the operation port is opened per normal symbol. , The winning rate to the operating opening is increased.

  Recently, a pachinko machine having a probability variation mode set is known. The probability variation mode refers to the case where the jackpot symbol is a special symbol such as “3”, “3”, “3”, “7”, “7”, “7”. The occurrence probability of the jackpot state is increased until the jackpot state is generated once (or twice), and the normal mode is selected in the case of a non-special symbol other than the special symbol. In addition to this, the fluctuation time of the special symbol variation display device is shortened, or the probability that the normal symbol variable display device is per ordinary symbol is increased.

  However, in the case of a pachinko machine with a probability variation mode set, if a jackpot symbol is selected and the jackpot symbol is a special symbol opposite to the probability variation mode, the probability variation mode is set. If it is a symbol, the mode is shifted to the normal mode. For this reason, whether the probability variation mode is selected or the normal mode is selected in advance by the ratio of the number of special symbols and the number of non-special symbols. That is, the probability on the surface and the actual probability are always the same whether or not the probability variation mode is selected. As a result, for the designer of the pachinko machine, it is necessary to manipulate the probability on the surface in order to change the probability that the probability variation mode is selected, and design changes such as changing the display contents have been forced. . This problem also applies to a pachinko machine equipped with a so-called time reduction mode in addition to the probability variation mode.

The normal symbol display device 51 can store the number of times the game ball 5 has passed through the passage gate 54 up to four times, and the hold lamp 52 displays the hold number. Therefore, even if the game ball 5 passes through the passing gate 54 with the four holding lamps 52 lit, it is not counted. As long as the holding lamp 52 is lit, the gaming ball 5 passes through the passing gate 54. The normal symbol display device 51 is activated as many times as the number of holdings.

  As shown in FIGS. 2 (a) and 2 (b), in the display unit 13 a of the special symbol display device 13, the symbol variation (rotational variation) of each symbol row 14 to 16 wins the operating port 3 of the game ball 5. Is started on the basis of Also, one of the jackpot symbol, the missed reach symbol, and the missed symbol is selected and set as a stop symbol. The stop symbol is a symbol displayed when each symbol row 14 to 16 stops symbol variation. In the present embodiment, the symbol variation is stopped in the order of the left symbol row 14, the right symbol row 16, and the middle symbol row 15, but this is only an example, and it should be stopped in a different order. Also good.

  The jackpot symbol is a symbol for generating a jackpot state as a special gaming state advantageous to the player after the reach state. Specifically, as shown in FIG. 4 (b), when the variation of all the symbol rows 14 to 16 is stopped, the combination of the displayed symbols 17A to 17L becomes a predetermined jackpot combination. There is a case. That is, when the same types of symbols 17A to 17L are arranged along the jackpot line, combinations of the same symbols 17A to 17L (for example, symbols 17A of "1", "1", and "1" in FIG. 4B) The symbol that makes up this combination is a “big jackpot symbol.” When the jackpot combination is established, a special electric accessory is actuated (the big prize opening 4 is opened), which is a jackpot that is advantageous to the player. A state is generated, i.e., more prize balls can be acquired.

  Further, as shown in FIGS. 5A and 5B, the reach state means a state immediately before the big hit. The reach state includes a state in which the symbol variation in the right symbol row 16 stops at the same kind of symbol as the stop symbol in the left symbol row 14 on the jackpot line.

  In the above reach state, the symbol variation of the middle symbol row 15 will eventually stop at the same kind of symbols (big hit symbol) as the stop symbols of both the left and right symbol rows 14 and 16 and become a big hit state Also included are those that stop at different types of symbols (this is referred to as “outgoing reach design”) and do not become a big hit state (hereinafter referred to as “outgoing reach state”). Furthermore, after the symbol variation of the middle symbol row 15 is temporarily stopped, all the symbol rows are changed again in a state where the symbols 17A to 17L of the same type are arranged along the jackpot line, and thereafter, the symbols of all the symbol rows 14 to 16 are changed. The case where symbols 17A to 17L stop simultaneously (also referred to as re-variation full rotation reach) is included.

  In the reach state, various reach patterns are set. As the reach pattern, various reach patterns such as “normal reach”, “hammer reach”, and “stocking reach” are set. Among these reach patterns, reach patterns other than “normal reach” are so-called “super reach”. When the operation of “super reach” is started, the expected value (expected value for jackpot) at which a big hit state occurs is higher than in the case of “normal reach”. In “Super Reach”, the expected value of jackpots varies depending on each reach pattern. Note that each of the reach patterns is not directly related to the present invention, and therefore further explanation is omitted here.

  Although it has already been described that the symbol variation of each symbol row 14 to 16 is started based on the winning of the game ball 5 to the operation port 3, when the game ball 5 further wins the operation port 3 during this variation display In the same manner as in the case of passing through the passage gate 54, the corresponding change display is performed after the end of the current change display. That is, the variable display is waited (held). The maximum number of variable displays to be held is determined for each model of pachinko machine. In the present embodiment, the maximum number of holds is set to 4 times, but is not limited to this.

  As shown in FIG. 1, in the special symbol display device 13, holding lamps 18a, 18b, 18c, and 18d made of light emitting diodes (LEDs) are incorporated above the display unit 13a. The number of the hold lamps 18a to 18d is the same as the above-described maximum hold number (in this case, 4). The hold lamps 18a to 18d are turned on every time the variable display is held, and are turned off when the variable display corresponding to the hold is executed. In addition, various lamps and electrical decoration members for enhancing the gaming effect are attached to a plurality of locations of the pachinko machine 1. These lamps and the like can be turned on (turned off, turned on, blinked, etc.) as the game progresses. Furthermore, the pachinko machine 1 is provided with a speaker (not shown) that generates sound effects as the game progresses.

  In the present embodiment, the game board 2 includes a through switch 20, an operating port switch 21, a V zone switch 22, and a count switch to detect the gaming state of the pachinko machine 1 that changes in accordance with the player's operation. 23 is attached. The through switch 20 detects the passage of the game ball through the passage gate 54, and the operation port switch 21 detects the winning of the game ball 5 to the operation port 3. Further, the V zone switch 22 detects a winning in the V zone 8 among the big winning openings 4 of the game ball 5, and the count switch 23 detects a winning in the big winning opening 4 of the game balls 5.

  In the present embodiment, the solenoids 10 and 12, the special symbol display device 13, the holding lamps 18a to 18d, the normal symbol display device 51 (the 7-segment display unit 53 and the holding lamp 52) based on the detection results of the switches 20 to 23. A control device 24 is provided to drive and control the blades 6 and the like. The control device 24 includes a read only memory (ROM), a central processing control device (CPU), a random access memory (RAM), and the like. The ROM stores a predetermined control program and initial data in advance, and the CPU executes various arithmetic processes according to the ROM control program. The RAM temporarily stores the calculation results by the CPU in the symbol random number buffers 31 to 36 shown in FIG. 6, the symbol random number areas 41 (i) to 45 (i) shown in FIG. 7, the stop symbol areas 46 to 48 shown in FIG. Remember me.

  As shown in FIG. 6, the symbol random number buffer includes three left, middle, and right out symbol random number buffers 31, 32, and 33, and three left, middle, and right out symbol design random number buffers 34, 35, and 36. It is constituted by. As shown in FIG. 7, the design random number area includes five internal random number areas 41 (i), five outreach reach random number areas 42 (i), five left left design random number areas 43 (i), and five It is composed of an out-of-line design random number area 44 (i) and five out-of-right design random number areas 45 (i). i is for distinguishing each of the five design random number areas, and takes values of “0”, “1”, “2”, “3”, and “4”. Each value of i corresponds to the number of variable displays held. Further, as shown in FIG. 8, the stop symbol area is composed of left, middle, and right stop symbol random number areas 46, 47, and 48.

  Further, in the present embodiment, there is a game mode switching control as one of the controls by the CPU (control device 24). In the present embodiment, basically two modes are prepared. That is, for example, a normal mode in which a jackpot gaming state is generated with a low probability of about 1/300 and a high probability mode in which a jackpot gaming state is generated with a high probability of about 1/60, which is about five times (hereinafter, for convenience. It is referred to as “probability mode”.

  In general, the concept of the probability variation mode is as follows: (1) The probability that “7” is displayed on the 7-segment display unit 53 is increased compared to the normal time, and the opportunity to open the blades 6 of the operation port 3 is increased. , (2) shortening the fluctuation time of the numbers in the 7-segment display section 53, (3) increasing the opening time of the blades 6 (and / or increasing the number of winning prizes), (4) special symbol display device 13 display parts 13a 17A to 17H, 17K variation time is shortened, (5) jackpot probability is higher than the normal mode, etc. In the probability variation mode in the present embodiment, In addition to (5), all items (1) to (4) are executed.

  When the pachinko machine 1 is turned on, the normal mode is set. After that, the next game mode is notified in relation to the symbols 17A to 17L (the jackpot symbol) when the jackpot gaming state is reached. More specifically, in the case of a big hit with the even numbered symbols 17B, 17D, 17F, 17H, 17J, 17L of “2”, “4”, “6”, “8”, “10”, “12” As a result, in the next game, the normal mode is set. In addition, in the case of a big hit with odd numbers 17A, 17C, 17E, 17G, 17I, 17K of “1”, “3”, “5”, “7”, “9”, “11”, the result Therefore, in the next game, the probability variation mode is set.

  In addition, in the present embodiment, there is limiter control as another control by the CPU (control device 24). This limiter control is executed in order to suppress gambling for the player, and controls the probability variation mode not to exceed a predetermined number of times. More specifically, when the CPU is in the probability variation mode four times in succession, the CPU controls to be in a mode other than the probability variation mode, that is, in the normal mode at the fifth big hit (limiter time). That is, at the time of the limiter, it is a big hit with any of the symbols 17B, 17D, 17F, 17H, 17J, and 17L among the symbols “2”, “4”, “6”, “8”, “10”, and “12”. Control to do.

  Further, in the present embodiment, the probability that the probability variation mode (or normal mode) is given is different from the display probability (1/2). That is, in the present embodiment, when the jackpot state occurs, the probability variation mode is assigned with a probability of 7/15, and the normal mode is assigned with a probability of 8/15.

  Next, the operation and effect of the pachinko machine 1 configured as described above will be described. The flowcharts of FIGS. 10 to 16 show various routines executed by the control device 24. The processing of these routines is executed based on the counter group, the winning determination flag FE, and the like. The counter group includes a round counter CR, a hold counter CH, a winning counter CE, an internal random number counter CI, a missed reach random number counter CO, a normal jackpot symbol random number counter CBT, a probability change jackpot symbol random number counter CBK, each of left, middle and right It consists of symbol random number counters CDL, CDC, CDR, reach type determination counter CV, game mode determination counter CF and the like.

  The round counter CR is for counting the number of rounds, and the winning counter CE is for counting the number of winning game balls 5 to the big winning opening 4. The hold counter CH is for counting the number of hold times of the variable display, and takes values of “0”, “1”, “2”, “3”, “4” in order. These values correspond to “(i)” in the above-described symbol random number areas 41 (i) to 45 (i). Therefore, CH = 0 means a state that is not reserved.

  As shown in FIG. 9A, the internal random number counter CI is for determining a jackpot state in the special symbol display device 13. Further, the outreach random number counter CO is for determining whether or not to display in the outreach state. Furthermore, the normal jackpot symbol random number counter CBT is for determining the jackpot symbol when the determined game mode is the normal mode, and the probability change jackpot symbol random number counter CBK is the probability change of the determined game mode. This is for determining the jackpot symbol in the mode. Each of these counters CI, CO, CBT, and CBK updates the value within a predetermined range every predetermined time (for example, “2 ms”). Each value is read as a random number according to a predetermined condition. Further, each counter CI, CO, CBT, CBK is set back to the initial value when each value becomes a specific value.

  The left, middle, and right symbol random number counters CDL, CDC, CDR are for determining stop symbols and the like. The left symbol random number counter CDL updates the value within a predetermined range every predetermined time (for example, “2 ms”), and returns it to the initial value when it reaches a specific value. The middle symbol random number counter CDC updates the value within a predetermined range every time the left symbol random number counter CDL makes a round, and returns it to the initial value when it reaches a specific value. The right symbol random number counter CDR updates the value within a predetermined range every time the middle symbol random number counter CDC makes a round, and returns it to the initial value when it reaches a specific value.

  Further, the reach type determination counter CV shown in FIG. 9B is used for selecting one of the above-described multiple types of reach patterns. For example, every time the left symbol random number counter CDL makes a round. The value (random value) is updated, and when it reaches a specific value, it is returned to the initial value. However, each reach pattern is weighted, and the probability that each reach pattern is selected is individually different. Further, in the present embodiment, the probability that each reach pattern is selected differs depending on whether it is a big hit (at the time of big hit) or a case of a big hit (at the time of outreach).

  Further, as shown in FIG. 9 (c), the game mode determination counter CF is used for determining the game mode, and takes values of “0” to “14”, for example, the left symbol random number counter. The value (random number value) is updated every time the CDL makes a round, and when it reaches a specific value, it is returned to the initial value. When the values “0” to “6” are adopted, the probability variation mode is assigned, and when the values “7” to “14” are adopted, the normal mode is assigned. .

  The winning determination flag FE is used to determine whether or not there is a winning in the V zone. The flag FE is set to “0” when there is no winning, and is set to “1” when there is a winning.

  The flowchart of FIG. 10 discriminates combinations of the values (random numbers) of the design random number counters CDL, CDC, CDR after updating the counters CI, CO, CBT, CBK, CDL, CDC, CDR, CV, CF described above. (Random distribution), and the “random number distribution routine” for storing the distributed values in the corresponding symbol random number buffers 31 to 36 is shown. This routine is executed every predetermined time (2 ms) after the pachinko machine 1 is powered on. When this routine is started, the control device 24 first adds “1” to the internal random number counter CI, the missed reach random number counter CO, the normal time big hit symbol random number counter CBT, and the probability variation big hit symbol random number counter CBK in step S1. Do (update).

  In step S2, “1” is added to the left symbol random number counter CDL. The middle / right symbol random number counters CDC and CDR are updated according to the values of the left and middle symbol random number counters CDL and CDC, respectively. Specifically, “1” is added to the middle symbol random number counter CDC at the timing when the left symbol random number counter CDL is returned to the initial value, and the value of the counter CDC is maintained at other timings. Further, if the middle symbol random number counter CDC is returned to the initial value, “1” is added to the right symbol random number counter CDR, and if not, the value of the counter CDR is maintained. Further, in step S3, the control device 24 updates the reach type determination counter CV and the game mode determination counter CF.

  Next, in step S4, it is determined whether or not the combination of the values of the symbol random number counters CDL, CDC, CDR is a predetermined “combination symbol combination”. If this condition is satisfied, the values of the symbol random number counters CDL, CDC, CDR are stored in the corresponding off symbol random number buffers 31, 32, 33 in step S5. Here, the corresponding out symbol random number buffers 31 to 33 specifically refer to the left symbol random number buffer 31 for the left symbol random number counter CDL, and the symbol symbol random buffer 32 for the middle symbol random number counter CDC. The right symbol random number counter CDR indicates the off-right symbol random number buffer 33 (the same applies to step S7 described later). And the control apparatus 24 once complete | finishes the subsequent process, after performing the process of step S5.

  On the other hand, if the condition of step S4 is not satisfied, whether or not the combination of the values of the design random number counters CDL, CDC, CDR is a predetermined “combination of outreach symbols” in step S6. Judging. If this condition is satisfied, the values of the symbol random number counters CDL, CDC, CDR are stored in the corresponding outreach symbol random number buffers 34, 35, 36 in step S7, and the subsequent processing is temporarily terminated. .

  If the condition in step S6 is not satisfied, the “random number distribution routine” is terminated without performing any of the processes in steps S5 and S7. In this case, the combination of the values of the respective symbol random number counters CDL, CDC, CDR is not a combination of an outlier symbol or an outlier reach symbol, that is, a combination of jackpot symbols.

  Thus, in the “random number distribution routine”, combinations of the values of the three symbol random number counters CDL, CDC, and CDR are checked every predetermined time. In the case of a combination of outliers, random numbers are stored in the outlier symbol random buffers 31-33, and in the case of an outlier design, random numbers are stored in the outlier symbol random buffers 34-35. In the case of a jackpot symbol combination, random numbers are not stored in any symbol random number buffers 31-36.

  Next, the “storage processing routine” shown in the flowchart of FIG. 9 will be described. The main function of this routine is to store the values of the random number counters CI, CO, CDL, CDC, CDR in the symbol random number areas 41 (i) to 45 (i) every time the game ball 5 wins the operating port 3. That is.

  When the “storage process routine” is started, the control device 24 determines whether or not the game ball 5 has won the operating port 3 based on the detection result of the operating port switch 21 in step S10. If the determination condition is not satisfied, the subsequent processing is temporarily terminated. If the determination condition is satisfied, the value of the hold counter CH is the maximum hold count (in this case, “4”) in step S11. Or less.

  If the value of the hold counter CH is smaller than the maximum hold count, “1” is added to the hold counter CH in step S12. In the following step S13, the control device 24 lights the corresponding holding lamp (one of 18a to 18d), and proceeds to step S14. On the other hand, if the determination condition of step S11 is not satisfied, the subsequent processing is temporarily terminated without performing the processing after step S12 described above. Therefore, the symbol variation display is held only up to four times, and the hold is not stored even if there are more winnings.

  In step S14, the control device 24 stores the value of the internal random number counter CI in the internal random number area 41 (i). In the next step S15, the value of the outreach random number counter CO is stored in the outreach random number area 42 (i). Further, in step S16, the control device 24 uses the values (CDL, CDC, CDR) of the left, middle, and right off symbol random number buffers 31 to 33 as the corresponding left, middle, and right off symbol random number areas 43. (I) to 45 (i), and the subsequent processing is temporarily terminated.

  As described above, in the “storage processing routine”, the values of the random number counters CI, CO, CDL, CDC, CDR are stored in the symbol random number areas 41 (i) to 45 (i). In steps S14 to S16, for example, if the value of the hold counter CH after the update in step S12 is “3”, the internal random number area 41 (i = 3) and the outreach random number area 42 (i = 3). , The left off symbol random number area 43 (i = 3), the off center symbol random number area 44 (i = 3), and the right off symbol random number area 45 (i = 3) serve as storage locations in the current control cycle.

  Next, the “special electric accessory control routine” shown in the flowcharts of FIGS. 12 and 13 will be described. This routine is for controlling the special electric accessory using calculation results such as the above-mentioned “random number distribution routine”, “storage processing routine”, etc., and is executed every predetermined time after the pachinko machine 1 is turned on. Is done.

  When this “special electric accessory control routine” is started, the control device 24 first determines in step S20 whether or not the value of the hold counter CH is not “0”. When a negative determination is made, that is, when the value of the hold counter CH is “0”, the subsequent processing is temporarily ended. On the other hand, if the determination condition is satisfied (CH = 1, 2, 3, 4), “i” is set to “0” in step S30, and the hold counter CH is set in the next step S40. Is not the same as “i”.

  When this determination condition is satisfied (CH ≠ i), in step S50, the internal random number area 41 (i + 1), the outreach random number area 42 (i + 1), and the out symbol random number areas 43 (i + 1) to 45 Each data of (i + 1) is shifted to the previous area 41 (i) to 45 (i), respectively. Next, in step S60, the control device 24 adds “1” to “i” and returns to step S40.

  On the other hand, when the determination condition of step S40 is not satisfied (CH = i), the process proceeds to step S70, and the lamps 18a to 18d corresponding to the hold counter CH are turned off. In the next step S80, “1” is subtracted from the hold counter CH.

  Next, in step S90, the control device 24 executes symbol variation start processing. Specifically, as shown in the “variation start processing routine” of FIG. 14, it is determined in step S91 whether or not the value of the internal random number counter CI is a jackpot value. If the value of the internal random number counter CI is a jackpot value, a game mode is set in step S92, and the jackpot symbol corresponding to the set game mode is stored in the memory as a stop symbol (for this process) Will be described later). Thereafter, the process proceeds to step S95.

  On the other hand, if the determination condition in step S91 is not satisfied, it is determined in step S93 whether or not the value of the outreach random number counter CO is the same as the predetermined outreach value. If the value of the outreach random counter CO is the same as the outreach value, in step S94, the symbol corresponding to the outreach value (outreach reach symbol) is stored in the memory as a stop symbol, and the process proceeds to step S95. To do.

  If the determination condition in step S93 is not satisfied, in step S96, the off symbol in step S16 is stored in the memory as a stop symbol, and the process proceeds to step S97.

  Now, the process proceeds from step S92 or step S94, and in step S95, a reach pattern is acquired. That is, one of various reach patterns such as “normal reach”, “hammer reach”, and “stock reach” described above is determined based on the reach type determination counter CV.

  And it transfers from step S95 or step S96, and in step S97, the symbol fluctuation | variation of the special symbol display apparatus 13 is started, and a "variation start process routine" is complete | finished.

  Here, the processing content corresponding to step S92 will be described. That is, FIG. 15 shows a “hit jackpot / game mode determination routine” executed by the control device 24 in order to set the game mode and store the jackpot symbol corresponding to the set game mode in the memory as a stop symbol. It is a flowchart which shows. In the present embodiment, when the mode XMODE is “0”, it indicates the normal mode, and when it is “1”, it indicates the probability variation mode.

  When the processing shifts to this routine, the control device 24 first determines in step S9201 whether the number of consecutive occurrences of the big hit state is equal to or greater than the limiter value LMT (limiter control needs to be performed). If the number of consecutive occurrences of the big hit state is not equal to or greater than the limiter value LMT, it is determined that there is no need to perform limiter control, and the flow proceeds to step S9204.

  On the other hand, if the number of consecutive occurrences of the jackpot state is equal to or greater than the limiter value LMT, it is necessary to perform limiter control. In step S9202, the jackpot symbol (even number) is determined based on the normal jackpot symbol random number counter CBT. (Design) is determined and memorized.

  Further, in the subsequent step S9203, the mode XMODE is set to “0”, and the subsequent processing is temporarily ended.

  If the limiter control is not performed, it is determined in step S9204 whether or not the value of the currently selected game mode determination counter CF is a value (“0” to “6”) corresponding to the probability change mode. . If the value of the game mode determination counter CF is a value corresponding to the probability variation mode, in step S9205, a jackpot symbol (odd symbol) is determined based on the probability variation jackpot symbol random number counter CBK and stored. . Further, in the subsequent step S9206, the mode XMODE is set to “1”, and the subsequent processing is temporarily ended.

  If a negative determination is made in step S9204, that is, if the value of the game mode determination counter CF adopted this time is not a value corresponding to the probability variation mode (in the case of “7” to “14”), the above-described steps The process proceeds to S9202, where the jackpot symbol (even symbol) is determined based on the normal jackpot symbol random number counter CBT and stored, and in step S9203, the mode XMODE is set to “0”, and the subsequent processing is performed. Exit once.

  In this way, in the above “hit symbol / game mode determination routine”, the probability variation mode is set as the game mode with a probability of 7/15 regardless of the display probability, except at the time of the limiter. The normal mode is set with a probability of 8.

  As described above, after executing the processing of step S90 ("variation start processing routine"), the control device 24 converts the symbols 17A to 17L in the left and right symbol rows 14 and 16 in step S110 of FIG. The stop symbol stored in any one of the steps S92, S94, S96 is replaced. In addition, the symbol variation in both the left and right symbol rows 14 and 16 is stopped, and the symbols 17A to 17L after replacement are displayed in the left and right symbol rows 14 and 16.

  Next, in step S120, the control device 24 performs a reach operation process. For example, when the reach pattern acquired in step S95 is “normal reach”, the operation process is executed so that the symbols 17A to 17L in the middle symbol row 15 perform the normal scroll operation. When the reach pattern is “hammer reach”, the background of the display unit 13a is changed, and Kanna-chan (character) with a hammer is arranged and displayed. Then, Kanna-chan performs the operation by swinging down the hammer and hitting the middle symbol (symbols 17A to 17L), and accordingly, the symbols 17A to 17L are temporarily displayed in a deformable state. Is performed. Further, when the reach pattern is “purchase reach”, the symbols 17A to 17L (middle symbols) of the middle symbol row 15 first move upward, and the source (character), cat and tray are displayed on the display unit 13a. Is done. Then, as shown in FIG. 5 (b), the cat and Genji move in the left-right direction as if pulling the tray, and the symbols 17A-17L slide in the left-right direction alternately and are temporarily indistinguishable. Processing such as display to be transformed into a state is performed.

  As described above, after executing the processing of step S120 (“reach operation processing routine”), the control device 24 stops the symbol variation in the middle symbol sequence 15 in step S130 (see FIG. 12).

  Subsequently, the control device 24 executes a re-variation process in step S135. Specifically, it is determined whether or not a condition for executing the re-variation process is satisfied, and when the re-variation process execution condition is satisfied, all the symbols have the same background as each reach operation in the reach operation process. The symbols 17A to 17L in the columns 14 to 16 are simultaneously changed again. And after predetermined conditions are satisfied, symbols 17A-17L of all symbol sequences 14-16 are stopped. On the other hand, if the condition for executing the re-variation process is not satisfied, no process is executed.

  Now, after performing the said re-variation process, the control apparatus 24 determines whether the combination of symbol 17A-17L is a jackpot combination in step S140 next. At this time, it is also confirmed whether or not the replacement of the stop symbol has been performed correctly. If this determination condition is not satisfied, the “special electric accessory control routine” is terminated. If the combination of symbols 17A to 17L is a jackpot combination (this is also the case when re-change is actually performed), the round counter CR is cleared to “0” in step S150. . At this time, the jackpot notification is displayed by the control device 24.

  Next, in step S160 (see FIG. 13), the control device 24 clears the winning counter CE to “0” and sets the winning determination flag FE to “0”. In the subsequent step S170, the round counter CR is incremented by “1”.

  Furthermore, in step S180, the control device 24 excites the special winning opening solenoid 12. Then, the shutter 11 falls down and becomes substantially horizontal, and the special winning opening 4 is opened. With this opening, the game ball 5 can be awarded to the V zone 8 and the winning path 9.

  Next, in step S190, the control device 24 determines whether or not the value of the winning counter CE is smaller than a predetermined value CEmax. Then, if this determination condition is satisfied, it is determined in step S200 whether or not the scheduled closing time of the special winning opening 4 is still open. If the scheduled closing time has not arrived, the process returns to step S190. As a result, after the opening of the big winning opening 4 is started, the big winning opening 4 is continuously opened unless more game balls 5 win the predetermined value CEmax or the scheduled closing time comes. On the other hand, if either step S190 or step S200 is not satisfied, the control device 24 demagnetizes the special winning opening solenoid 12 in step S210. Then, the shutter 11 is raised to be in a substantially vertical state, and the special winning opening 4 is closed.

  Subsequently, in step S220, the control device 24 determines whether or not the value of the round counter CR is equal to or smaller than a predetermined value CRmax. If the value of the round counter CR is equal to or smaller than the predetermined value CRmax, it is determined in subsequent step S230 whether or not the winning determination flag FE is “1”. If the winning determination flag FE is “1”, the process returns to step S160. Therefore, once the big hit gaming state occurs, the big winning opening 4 repeats the opening / closing cycle until the continuation condition by the game ball 5 winning the V zone 8 is satisfied a predetermined value CRmax times. For example, when the predetermined value CEmax is set to “10”, the opening time of the big winning opening 4 is set to “about 29.5 seconds”, and the predetermined value CRmax is set to “16”, the big winning opening is set. After the opening of 4, the game is won 5 when one of the following conditions is satisfied: (1) 10 game balls 5 win the grand prize opening 4 and (2) about 29.5 seconds have passed. The mouth 4 is closed. The opening / closing cycle of the big winning opening 4 is repeated up to 16 times (16 rounds) on condition that the game ball 5 wins the V zone 8.

  And when either one of the determination conditions of step S220 or step S230 is not satisfy | filled, it is displayed on the display part 13a that the jackpot state was complete | finished. At the same time, a process for informing the mode is executed. More specifically, as shown in the “mode notification processing routine” of FIG. 16, in step S2401, the control device 24 determines whether or not the current mode XMODE is “0”, and when the determination is affirmative. In step S2402, the display unit 13a displays that it is in the normal mode.

  If a negative determination is made, it is assumed that the current mode XMODE is “1”, and in step S2403, the display unit 13a is notified that the mode is the probability variation mode. The notification includes, for example, changing the background screen on the display unit 13a, displaying characters, turning on a lamp, or notifying by voice.

  And after performing the said mode alerting | reporting process, the control apparatus 24 once complete | finishes a "special electric accessory control routine."

  As described above in detail, according to the present embodiment, the game mode is determined independently based on the game mode determination counter CF when the big hit state occurs. In other words, based on the game mode determination counter CF, it is determined whether the normal mode is given or the probability change mode is given at the next game. And based on the decision result, it decided to decide the jackpot design. Therefore, it is possible to set the probability (giving) probability of the probability variation mode without being restricted by the probability variation mode probability (1/2) on the surface. As a result, the degree of freedom in design increases.

  In particular, in this embodiment, the probability variation mode occurrence probability on the surface is 1/2, whereas the probability that the probability variation mode actually occurs is set to 7/15, and this probability is It can be set arbitrarily. Therefore, it is possible to improve the interest for the player, and in some cases (by appropriately changing the actual occurrence probability), the pachinko machine 1 may have the same appearance but with a different probability variation mode occurrence probability. It is also possible to design.

  That is, conventionally, when trying to manufacture pachinko machines having different probability variation mode occurrence probabilities, it is necessary to appropriately vary the number and types of symbols. On the other hand, in the present embodiment, by appropriately adjusting the game mode determination counter CF and the like, it is possible to easily design the probability variation mode occurrence probability as appropriate, and to easily finely adjust the probability. Can be done.

(Second Embodiment)
Next, a second embodiment in which the gaming machine is embodied as a pachinko machine will be described based on the drawings. Also in the present embodiment, the probability that the probability variation mode (or normal mode) is given is different from the display probability (1/2), as in the first embodiment described above. That is, also in this embodiment, when the jackpot state occurs, the probability variation mode is assigned with a probability of 7/15, and the normal mode is assigned with an probability of 8/15.

  However, in the present embodiment, the game mode determination method and the jackpot symbol determination method at the time of jackpot are greatly different from those of the first embodiment, and the following description will focus on the differences described above. I will do it. In this embodiment, for the sake of convenience, the limiter control as described in the first embodiment is not performed (of course, the limiter control may be performed).

  In the first embodiment, it is determined based on the game mode determination counter CF whether the probability variation mode should be given or the normal mode should be given, and depending on the decision result, the probability variation jackpot symbol random number counter CBK or The jackpot symbol is determined based on the normal jackpot symbol random number counter CBT. On the other hand, in this embodiment, the game mode determination counter CF is not used, and instead of the two types of counters CBK and CBT, one type as shown in FIG. This is characterized in that only the jackpot symbol random number counter CB is used. The jackpot symbol random number counter CB is updated every predetermined time (for example, “2 ms”) in the same random number distribution routine as in FIG. 10 in the same manner as the above two types of counters, and returns to the initial value when it reaches a specific value. It is supposed to be.

  In the present embodiment, for convenience of explanation, the denominator value of the probability that the probability variation mode should be given is referred to as TBB (TBB = 15), and the numerator value of the probability that the probability variation mode is actually given is TBS (TBS = 7). Furthermore, the number of symbols to which the probability variation mode is to be assigned (for convenience, referred to as the number of symbols with probability variation: this is equal to the number of symbols to which the normal mode is to be imparted) is referred to as TS. Also in the present embodiment, the types of symbols are the same as those in the first embodiment described above, and therefore the probability variation symbol number TS is “6”. The jackpot symbol random number counter CB is set to take a value obtained by multiplying the denominator value TBB by the probability variation symbol number TS, that is, 15 × 6 = 90 (numbers) in this embodiment. Accordingly, the jackpot symbol random number counter CB starts from “0” and is incremented by “1”. When the jackpot symbol random number counter CB reaches a specific value (“89”), the initial value is reset to “0”.

  Now, the game mode and jackpot symbol determination method in the present embodiment will be described in detail. FIG. 18 is a flowchart illustrating a “hit symbol / game mode determination routine” executed by the control device 24. In step S9211, the control device 24 first substitutes (applies) each numerical value that is currently set and input (initially set) to TS, TBS, and TBB that are algebras. For example, in the present embodiment, 15 is substituted for the denominator value TBB, 7 is substituted for the numerator value TBS, and 6 is substituted for the probability variation symbol number TS. Of course, each value may be set in advance as TS, TBS, and TBB, and step S9211 may be omitted.

  Next, in step S9212, the control device 24 divides the current value of the jackpot symbol random number counter CB by the probability variation symbol number TS, obtains the remainder, and sets the value as the remainder value D. Here, the probability variation symbol number TS is “6 (:“ one ”,“ three ”,“ five ”,“ seven ”,“ nine ”,“ eleven ”)” in the present embodiment. The remainder value D takes any integer value from “0” to “5”.

  Further, in the following step S9213, it is determined whether or not the current value of the jackpot symbol random number counter CB is equal to or greater than a value obtained by multiplying the probability variation symbol number TS and the probability numerator value TBS. In the present embodiment, the number of jackpot symbol random number counter CB is TBB × TS (90 patterns: “0” to “89”), while the value obtained by multiplying the probability variation symbol number TS and the probability numerator value TBS is “42”. Therefore, the case where an affirmative determination is made in step S9213 is a case where the value of the jackpot symbol random number counter CB is “42” or more and “89” or less. That is, the probability of affirmative determination is 48/90 = 8/15. On the other hand, the case where a negative determination is made in step S9213 is a case where the value of the jackpot symbol random number counter CB is “0” or more and “41” or less. That is, the probability of a negative determination is 42/90 = 7/15.

  If a negative determination is made in step S9213, the control device 24 sets the mode XMODE to “1” in step S9214 in order to give the probability variation mode. Therefore, in this embodiment, the mode XMODE is set to “1” with a probability of 7/15.

  Further, in step S9215, the control device 24 determines a jackpot symbol by referring to the “probability variation symbol determination table” shown in FIG. 19A based on the remainder value D set in step S9212. Then, the subsequent processing is temporarily terminated. Here, as described above, the remainder value D is an integer value of “0” to “5”. For this reason, as shown in the table, when the remainder value D is “0”, the symbol “1” is “1”, and when the remainder value D is “1”, the symbol “3” is the remainder 17C. When D is “2”, the symbol 17E of “5” is displayed. When the remainder value D is “3”, the symbol 17G of “seven” is displayed. When the remainder value D is “4”, “9” is displayed. If the symbol 17I of FIG. 1 is a remainder value D of “5”, the symbol 17K of “11” is selected and determined so that each remainder value D and the jackpot symbol are in a one-to-one correspondence. The jackpot symbol at the time of probability change is determined at an equal rate.

  On the other hand, if an affirmative determination is made in step S9213, control device 24 sets mode XMODE to “0” in step S9216 to give the normal mode. Therefore, in this embodiment, the mode XMODE is set to “0” with a probability of 8/15.

  In further subsequent step S9217, the control device 24 determines the jackpot symbol by referring to the “normal symbol determination table” shown in FIG. 19B based on the remainder value D set in step S9212. Then, the subsequent processing is temporarily terminated. Here, as described above, the remainder value D is an integer value of “0” to “5”. Therefore, as shown in the table, when the remainder value D is “0”, the symbol “2” is “2”, and when the remainder value “D” is “1”, the symbol “4” is the residue value “D”. When D is “2”, the symbol “17” of “six” is displayed, when the remainder value “D” is “3”, the symbol “H” is “H”, and when the remainder value “D” is “4”, “ten”. If the symbol 17J of the symbol is J5 and the remainder value D is “5”, each symbol D and the jackpot symbol should be in a one-to-one correspondence such that the symbol “12” is selected and determined. The jackpot symbol at the normal time is determined at an equal rate.

  Thus, according to the present embodiment, in addition to the operational effects described in the first embodiment, the denominator TBB of the probability that the probability variation mode should be given, the numerator of the probability that the probability variation mode is given. By setting the value TBS and the probability variation symbol number TS in advance, the probability variation mode of the probability variation mode is not constrained by the probability variation mode occurrence probability (1/2) on the surface when the big hit state is generated through the above processing routine. The occurrence (granting) probability can be a different probability. Further, by adopting the above configuration, the program data area can be compressed, and the control contents can be significantly simplified. In particular, in the present embodiment, unlike the first embodiment, it is not necessary to use two types of counters, that is, the probability variation jackpot symbol random number counter CBK and the normal time jackpot symbol random number counter CBT. For this reason, the above-described effects can be achieved more reliably.

  Further, by using the concept of the remainder value D and setting on the table so that the remainder value D and the jackpot symbol have a one-to-one correspondence, the determined ratio of the jackpot symbol under each mode becomes equal. . As a result, it is possible to eliminate problems caused by the occurrence of bias in the jackpot symbol.

  In addition, if there is a model change, specification change, etc., the above processing contents should be applied to all numerical values by simply setting the denominator value TBB of probability, the numerator value TBS of probability, and the probability variation symbol number TS as appropriate. Can do. That is, in this embodiment, the probability variation symbol number TS is set to 6 (the number of symbols to which the normal mode is given is 6), but for example, the probability variation symbol number TS is 25 (in this case, the number of symbols to which the normal mode is assigned is also 25). In the present embodiment, the probability that the probability variation mode is given is set to 7/15, but may be set to 4/9, for example. In such an example, the denominator value TBB of the probability that the probability variation mode should be given is 9, the numerator value TBS of the probability that the probability variation mode is actually given, and further, the probability variation mode should be given. The number of symbols TS is 25. Therefore, the jackpot symbol random number counter CB is set to take 9 × 25 = 225 values (0 to 224). When the value of the jackpot symbol random number counter CB is 0 to 99, the probability variation mode is given. When the value of the jackpot symbol random number counter CB is 100 to 224, the probability variation mode is given. That is, the probability variation mode is assigned with a probability of 4/9, and in that case, the jackpot symbol to which the probability variation mode is imparted is determined at an equal ratio based on the remainder value D (the same applies to the normal mode). In this way, it is possible to easily cope with model changes, specification changes, and the like, and as a result, it is possible to significantly reduce costs and significantly improve design freedom.

  In the present embodiment, the control device 24, that is, the main board is configured to manage the occurrence of a jackpot state, the determination of the game mode, and the determination of the jackpot symbol. On the other hand, instead of the control device (main substrate) 24, various displays on the display unit 13a may be controlled mainly on the control substrate of the variable display device 13. That is, the control device (main board) 24 is configured to output (transmit) a display command as a display control command to the variable display device 13 when executing the symbol variation. The display command includes only time information indicating that the symbols 17A to 17L are fixedly displayed after a predetermined time from the start of variation, display pattern information indicating a variation pattern represented by each reach pattern, and the like. It is configured such that the symbol information indicating which symbols 17A to 17L are to be confirmed and displayed is not included. In this case, the fixed symbol including the jackpot symbol is determined on the variable display device 13 side. Therefore, the control contents of the control device (main board) 24 can be significantly simplified. In this case, “the determined symbol is determined not by the main control unit that controls the main control but by the display control unit on the symbol display means side” is a feature point.

  Furthermore, in the present embodiment, the concept of the remainder value D is used, and the remainder value D and the jackpot symbol are set on the table so as to correspond one-to-one. On the other hand, it is good also as a structure which does not necessarily respond | correspond one by one. For example, a configuration may be adopted in which a symbol is not set on the table so that a certain symbol is not confirmed and displayed as a jackpot symbol. Moreover, it is good also as setting on a table so that a certain symbol may be more easily stopped and displayed as a jackpot symbol than other symbols. By adopting such a configuration, it is possible to give a bias to the jackpot symbol displayed in a fixed stop state.

  For example, it is possible to make it easy to stop and display symbols that are familiar to the player such as “three” and “seven” (easy to feel joy). In addition, when a big hit state occurs with a predetermined symbol such as “4”, “6”, etc., the game hall adopts a system in which the paid game balls (balls) must be exchanged for prizes In this case, it is possible to increase the frequency of replacement by making it easy to generate a big hit state with the predetermined symbol. As a result, it is possible to adopt a game system-specific exchange system, and in such a case, it is possible to take a flexible and appropriate measure.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the probability variation mode is adopted as the special mode, and as a concept thereof, in addition to the jackpot probability being increased, (1) the probability that “7” is displayed on the 7-segment display unit 53 To increase the chance of opening the blade 6 of the operating port 3, (2) shortening the fluctuation time of the number in the 7-segment display unit 53, (3) lengthening the opening time of the blade 6. (And / or increasing the number of winning prizes) and (4) shortening the variation time of the symbols 17A to 17L of the display unit 13a of the special symbol display device 13 are all executed. On the other hand, in addition to increasing the jackpot probability, satisfying any one of (1) to (4) may be regarded as a probability variation mode. Further, as the special mode, a time reduction mode (time reduction mode) may be adopted instead of the probability variation mode. As the time reduction mode, any combination of (1) to (4) (for example, (1) and (2), (1) and (3), (1) and (4), (2) and (3), (2) and (4), (3) and (4), (1) and (2) and (3), (1) and (2) and (4), (1) and (3) and (4 ), (2), (3) and (4)) can be employed.

  (B) The time reduction mode and the probability change mode may be continued until the next big hit time, or continued for a predetermined number of rotation fluctuations (for example, 20 times, 100 times, etc.) of the symbols 17A to 17L. After that, it may be switched to the normal mode. Further, when the time reduction mode or the probability variation mode is selected, the special mode may be continued until the big hit state occurs twice or more. In addition, as a result, the number of continuations in the probability variation mode or the time reduction mode (the number of continuation occurrences of the jackpot state) may be made variable according to the jackpot symbol. For example, if the jackpot is “1”, “5”, “9”, or “11”, the probability variation mode is continued until the next jackpot, and if the jackpot is “3” or “7”, the jackpot is repeated one after another. The probability variation mode may be continued until.

  (C) Furthermore, in the first embodiment, the game mode determination counter CF is adopted when the big hit state occurs. However, based on the winning of the game ball 5 to the operation port 3 (holding lamps 18a to 18a). At the time of turning off 18d), the game mode determination counter CF may be adopted in advance. By adopting such a configuration, the game mode determination counter CF has already been adopted at the time of a big hit.

  (D) In the first embodiment, the limit value LMT is set to 5 in the limiter control, but it may be less or more. For example, the limit value LMT may be 100 times. Further, as in the second embodiment, the limiter control may not be particularly performed.

  (E) In the first embodiment, the normal mode is selected at the time of the limiter. However, another mode (for example, a probability variation mode with a limited number of times) may be selected.

  (F) In the above embodiment, the re-variation process is performed, but such a process may be omitted. In the re-variation process, the reach pattern until then is maintained. However, without maintaining such reach pattern, the symbols 17A to 17L of all the symbol sequences 14 to 16 are simply re-variable. It is good also as a structure. In addition, a reach pattern different from that used may be employed.

  (G) As the display device 13, in addition to the liquid crystal display described above, a CRT, a dot matrix, an LED, an electroluminescence (EL), a fluorescent display lamp, or the like may be used.

  (H) In the above embodiment, the normal symbol display device 51 variably displays the numbers from “0” to “9” and causes the 7-segment display unit 53 to display the segment, and the number is a predetermined value (this embodiment) In the embodiment, when stopping at “7”), the blade 6 of the working port 3 is opened for a predetermined number of seconds. On the other hand, you may make it display using other display methods (for example, lighting of a lamp etc.) other than 7-segment display. In addition to opening the blades 6, another operating port may be provided to open the shutter.

  (I) Counters relating to random numbers including jackpot symbol random number counters CBT, CBK, CB (internal random number counter CI, outreach reach random number counter CO, left / middle / right symbol random number counters CDL, CDC, CDR and reach type determination counter CV , Game mode determination counter CF, etc.) may be changed as appropriate. For example, a single random number counter may be used to determine a jackpot state, a missed reach state, or the like based on the value.

  (J) You may implement as a pachinko machine etc. of a different type from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a game ball is awarded in a predetermined area after the big hit symbol is displayed. In addition to pachinko machines, the present invention can be implemented as various gaming machines such as alepatchi, sparrow balls, and slot machines. In the slot machine, for example, the symbol is changed by operating the operation lever in a state where the symbol effective line is determined by inserting coins, and the symbol is stopped and confirmed by operating the stop button. Is. Accordingly, the basic concept of the slot machine is that it is provided with a symbol display means for displaying a fixed symbol after a symbol string consisting of a plurality of symbols is variably displayed, and is caused by the operation of a starting operation means (for example, an operating lever). The game starts on the condition that the symbol variation is stopped due to the operation of the stop operating means (for example, the stop button) or when a predetermined time elapses and the confirmed symbol at the time of the stop is a specific symbol. Slot machine having special gaming state generating means for generating a special gaming state advantageous to the user.

  (K) In the above embodiment, the mode is displayed at the end of the jackpot state (step S240), but such a display may not be performed. Further, it may be displayed at the time of jackpot or during jackpot. Further, after the jackpot, the display may be continued until the next jackpot. Moreover, you may make it alert | report a mode with a lamp | ramp or a sound besides displaying on a display part.

  (L) In each of the above embodiments, the probability variation mode is generated at 7/15, but the probability is arbitrary and can be changed as appropriate. Of course, the number of symbols can be arbitrarily changed.

  (M) “A gaming machine in which a plurality of symbol variation modes from when a symbol starts to vary until it becomes a confirmed symbol” is set. In this case, for example, the change in the symbol on the symbol display means can be simply switched and displayed, the rotation variation can be displayed around the axis, or the symbol can be switched and displayed while zooming up. Appropriately select multiple types from among various symbol variation modes, such as switching and displaying while crushing or extending and deforming symbols, or performing revariation processing on symbols that appear to have been temporarily stopped do it. In addition, “the expected value that the special gaming state is given depends on the variation mode (including blinking etc.) from when the symbol starts to change until the confirmed symbol is obtained.” Not only changes in symbols but also interests in symbol variations, the thickness of the game increases.

  (N) “When the number of symbol changes on the symbol display means is at or near the maximum number of reservations, the time from the symbol change start to the confirmation on the symbol display means (or / and the next symbol change start from the symbol confirmation The time until the symbol variation start condition is satisfied, for example, when a game ball is won at the symbol operating port, is less likely to be invalidated.

  (O) The display color of each display system is appropriately switched and controlled according to the difference between modes (for example, the normal mode and the probability variation mode) and the difference in expected value of jackpot. For example, when the expected value for the big hit is increased, control is performed so that the symbol is switched from green to red. Such color switching brings about effects such as clarifying to the player that the gaming state is different from the normal state and clearly indicating to the player that the expected value of the big hit has increased. The technical ideas derived from this are: “Switch the symbol display color according to the gaming state.”, “Switch the symbol display color according to the mode.” "The display should be switched according to the difference."

  (P) A display control device that controls the display device 13 as a symbol display means is provided separately from the main control device (control device 24) that controls the entire gaming machine, and the main control device sends the display control device to the display control device. Instead of outputting a command, a mode signal may be output, and the display control device may select and display a fixed symbol corresponding to the mode in accordance with the mode signal. In this case, it is only necessary to store the normal jackpot symbol random number counter CBT and the probability variation jackpot symbol random number counter CBK in the display control device, and the main controller side sets the probability without being aware of the type of the symbol or the display device 13. Etc. can be easily designed.

  (Q) As a selection between the normal mode and the special mode such as the probability variation mode, in addition to the type in which the notification is made according to the symbol type (odd number / even number) in the display device 13 (display unit 13a) as the symbol display means, Mode notification means may be provided for confirming whether or not the mode is selected after the symbol called the fourth symbol is changed. Further, the display mode of the lamp may be changed to display the mode, or the mode may be notified by sound such as voice or musical sound.

  (R) A plurality of game mode determination counters CF1, CF2,... Having different probabilities that the probability variation mode is selected as the game mode determination counter CF are provided. Whether to select may be determined at random, and mode determination and symbol determination may be performed based on the selected game mode determination counter CF1. In this case, the total probability of each probability variation mode entry probability of each game mode determination counter CF1, CF2,... Becomes the probability that the probability variation mode is actually selected. In this case, it is preferable that a game mode determination counter CF capable of obtaining a 100% probability change mode is provided, and a notification means for notifying which game mode determination counter CF is selected in advance by display or sound is provided. It is more preferable to leave it.

  (S) A plurality of game mode determination counters CF each having probability change mode entry probabilities set (preferably there are counters having different probability change mode entry probabilities from each other). On the side, the switching setting may be possible. In this case, the switching means needs to be arranged on the back side of the gaming machine so that it cannot be operated from the player side.
