In the apparatus, during the variation display of the symbol, the display control of the symbol is performed so that the expectation degree that the combination of the symbols that are stopped and displayed after the variation display of the symbol is win is temporarily visible. It is desirable to be configured.

  Since the present invention is configured so that the degree of expectation in the variation can be temporarily visually recognized during the variation display of the symbol using the symbol display device, there is no need to newly provide an accessory such as a probability indicator. Costs can be reduced and there is no risk of losing the freedom of layout in the game area. In addition, since the degree of expectation can be understood by looking at the symbol display device, the player does not need to move the line of sight to another display device, and can concentrate on the game. The present invention makes it possible for the player to enjoy the process from the start to the stop display of the change display of the symbols, which the player has been less interested in, by displaying the expectation level during the change of the symbols. be able to.

  In the present invention, the degree of expectation is configured to be displayed by the plurality of symbols (for example, a combination of drawn numbers and characters). For this reason, since it is not necessary to newly produce effect data for displaying the degree of expectation, it is possible to suppress the current memory capacity and to suppress complicated control. Here, the numbers and characters used to display the degree of expectation are not limited to those drawn in the symbol that forms the winning combination, but may be those drawn in a symbol that is not stopped and displayed, for example.

  Note that the ball game machine of the present invention includes an operation means that can be input by a player, and the expectation level display control means is configured to display a symbol on the symbol display device on condition that the input operation of the operation means. It is configured to perform display control of the symbol so that the expected degree that the combination of symbols stopped and displayed after the variation display of the symbol is win is temporarily visible during the variation display. Is desirable. With such a configuration, it is possible to provide a player with the right to select whether or not to display an expectation on the symbol display device, and to provide an amusing bullet ball game machine in which the player's will is reflected in the game. it can.

  It should be noted that the operation effective lamp 6a may be installed in another position where the player can see and operate, instead of being provided in the operation switch 6 as in the present embodiment. Further, so that it can be understood that the operation of the operation switch 6 has become effective, it may be notified by displaying a symbol or an image (in the symbol display device 20 or the like), or by voice (using a speaker or the like).

  The game area 10 includes a plurality of general winning holes 11 that serve as payout conditions for a winning ball, a starting winning opening 12 that serves as a payout condition for winning balls and a starting condition for changing the symbol of the symbol display device 20, and a grand prize opening. 13, an outlet 14 for collecting game balls, a windmill 15 that affects the falling of the hit ball, and a number of game nails (not shown). In the approximate center of the game area 10, a symbol display device 20 that displays images and symbols such as various effect patterns is provided.

  On the lower part of the symbol display device 20, there is provided a holding ball lamp 30 composed of four LEDs or the like for displaying the number of winning balls entered into the start winning opening 12 during the variation of the symbol by the symbol display device 20. . In this embodiment, with the upper limit being four, each time the start winning opening 12 is won (during symbol variation), the holding ball lamp 30 is turned on one by one. Then, each time the variation display of the variation symbol is started in the symbol display device 20, the lit holding ball lamps 30 are turned off one by one.

  In the pachinko machine PM configured as described above, when the player operates the hitting handle 5, the game balls are sent one by one from the ball receiving tray 4 to the hitting ball launching unit (not shown), with a strength corresponding to the operation amount. 10 hits the ball. The fired hit ball flows down to the above-described winning ports 11 and 12 or the out-port 14, and when winning is made to the above-described winning ports 11 and 12, a predetermined winning ball is paid out to the ball receiving tray 4. Further, when a hitting ball is won at the start winning port 12 of the above-described winning ports 11, 12, a predetermined winning ball is paid out to the ball receiving tray 4, and the symbol displayed on the symbol display device 20 starts to fluctuate. The operation enable lamp 6a of the switch 6 is turned on.

  Note that the operation valid lamp 6a is not necessarily turned on after the start of variation of the symbols displayed on the symbol display device 20 as in the present embodiment. For example, the operation valid lamp 6a is lit according to a random number lottery result or a game situation. Or can be set as appropriate.

  Here, when an input operation of the operation switch 6 is performed while the lamp 6a is lit, the symbol is temporarily displayed on the symbol display device 20, and the expected degree of the fluctuation is temporarily visible. Then, after the symbol variation display is performed again, the symbol is stopped and displayed. At this time, in the case of a combination of symbols (for example, 1 to 9) in which the symbol stopped and displayed on the symbol display device 20 is a predetermined winning combination, it becomes a big hit and is opened to facilitate winnings. When a hit ball is won at the big winning opening 13, a large amount of award balls are paid out to the player.

  The control device provided in the pachinko machine PM configured as described above will be described with reference to the drawings. 3 and 4 are block diagrams showing an outline of control by the control device. This control device controls the game by the game control means 50 which is composed of various electronic components such as a CPU, ROM, and RAM.

  The game control means 50 includes an operation detection device 6b that is incorporated in the operation switch 6 and detects an input (pressing) operation of the operation switch 6, and a general winning opening prize detection device 11a that is incorporated in the general winning opening 11. The start opening winning detection device 12a built in the start winning opening 12, the big winning opening winning detection device 13a built in the big winning opening driving means 711, and a specific area in the big winning opening driving means 711 (not shown). ) Built in the specific area passage detection device 13b and the like are electrically connected, and a detection signal is input to the game control means 50 from these.

  The game control means 50 performs various operation controls in accordance with the detection signals input as described above, and as this control object, an operation valid lamp 6a indicating that the operation of the operation switch 6 is valid, The prize ball payout device 45 for paying out the prize balls, the big prize opening driving device 13m for opening the big prize opening driving means 711, the symbol display device 20 for displaying images and symbols, the holding ball lamp 30 and the like are electrically connected. Connected to. These are all controlled based on a control signal from the game control means 50.

  Then, the control content of the game control means 50 is demonstrated. The game control means 50 includes a normal game execution means 60, a special game execution means 70, a high probability game setting means 80, and a payout control means 90 for controlling this game.

  The normal game execution means 60 is for executing / controlling the normal game of the pachinko machine PM, and the winning award winning prize processing means 61 for performing a process related to winning a prize at each winning opening provided in the game area 10; Special game transition determining means 62 for determining whether or not to shift from a game to a special game. The winning opening winning prize processing means 61 is not different from the conventional one, and a detailed description thereof is omitted here.

  The special game transition determination means 62 includes a symbol element acquisition means 621, a reserved ball information storage means 622, a winning random number determination means 623, an effect determination means 624, a symbol control means 625, and an expectation level display control means 626. I have.

  The symbol element acquisition means 621 is for acquiring an element for determining a symbol or an image to be displayed on the symbol display device 20 (for example, a hit random number, a stop symbol random number, an effect random number). The symbol element acquisition means 621a , Stop symbol random number acquisition means 621b and effect random number acquisition means 621c.

  The winning random number acquisition means 621a is for acquiring a random number for determining whether or not to generate a big hit (hereinafter referred to as a "winning random number"). For example, a random number of 0 to 65535 (65536 ways) generated by the hardware increment counter is acquired based on the winning signal from the start opening winning detecting device 12a described above. Note that the random number in the specification is a concept including a thing that functions as a random number because there is no regularity in the acquisition timing even if it is regular like an increment counter.

  The stop symbol random number acquisition means 621b is for acquiring a random number for determining a stop symbol to be displayed on the symbol display device 20 (hereinafter referred to as “stop symbol random number”). For example, the left symbol determination random number for acquiring 0-9 (10 patterns) random numbers for the left symbol, the middle symbol determination random number for acquiring 0-9 (10 patterns) random numbers for the middle symbol, and the right symbol It consists of the right symbol determination random number for acquiring 0 to 9 (10 types) random numbers.

  The effect random number acquisition means 621c is for acquiring a random number for acquiring an effect pattern (any of the effect pattern group memory 624b) (hereinafter referred to as “effect random number”). For example, 0 to 255 (256 types) of random numbers generated by the software increment counter are acquired by the random number determination means 623 before determining the hit.

  The reserved ball information storage unit 622 receives the winning information of the game ball that has won the start winning slot 12 (that is, detected by the start slot winning detection device 12a) during the symbol change display by the symbol control unit 625. This is for storing predetermined upper limit pieces (four pieces in this embodiment) corresponding to the sphere. In the present embodiment, a winning random number, a stop symbol random number, an effect random number, the number of reserved balls, and the like are stored as winning information. In addition, when a predetermined upper limit number of pieces of reserve ball winning information is stored in the holding ball information storage unit 622, even if more game balls win the start winning opening 12, the winning information for the game ball is not changed. Invalid because it is not memorized. That is, the information acquired for the four game balls passing through the start winning opening 12 during symbol variation can be stored, but the fifth and subsequent game balls may pass through the start winning opening 12. It is ignored and only prize balls are paid out. In the present embodiment, the upper limit value of the number of reserved balls that can be stored is four, but the present invention is not limited to this and can be changed as appropriate.

  The winning random number judging means 623 is for judging whether or not to play a special game according to the winning random number, that is, whether or not it is a big hit. For example, the hit value “0 to 200” stored in the ROM is compared with the random number value (one of 0 to 65535) acquired as the previous hit random number, and the random value is determined to be the hit value “0 to 200”. ”Is determined as“ winning ”. Note that, during the probability fluctuation described later, the high probability game setting means 80 causes the jackpot probability to be a high probability (that is, the hit value is “ 0 to 1280 ").

  The effect determining means 624 is for determining various effects in the symbol display device 20 when the symbol display device 20 starts the change of the symbol and then stops the display, and the stop symbol determining means 624a, An effect pattern group memory 624b and effect pattern selection means 624c are provided.

  The stop symbol determination means 624a is for determining a stop symbol according to the stop symbol random number. In this embodiment, the stop symbol is composed of a left symbol, a right symbol, and a middle symbol, and each symbol can display a number from 0 to 9. It should be noted that what is drawn on the design is not limited to numbers as in the present embodiment, and for example, a character such as a star can be used.

  The stop symbols include a winning symbol and a missing symbol. The winning symbol is a combination of symbols that are stopped and displayed after the variation display of the symbol when the random number determining means 623 determines that the game is a winning symbol. As shown in FIG. This is a combination of symbols in which the three numbers displayed on the left symbol, right symbol, and middle symbol all match. On the other hand, the lost symbol is a combination of symbols that are stopped and displayed after the symbol change display when the game is not determined to be a hit by the random number determining means 623 (that is, when the game is out). As shown in b) and (c), it is a combination of symbols in which the three numbers do not match.

  The effect pattern group memory 624b is a memory that stores a plurality of effect patterns in which a symbol variation process for stopping and displaying a stop symbol after the symbol display device 20 displays a variation symbol is displayed. As shown, a special hit effect pattern group memory P1, a normal hit effect pattern group memory P2, and a loss effect pattern group memory P3 are provided.

  The special winning effect pattern group memory P1 is selected when the winning random number determining means 623 is determined to be a winning symbol and the stop symbol is determined to be a probable variation symbol (in this embodiment, an odd number) in the winning symbol. This is a memory for storing a plurality of types of symbol effect patterns (special hit effect patterns) from the start of fluctuation to the stop of symbols.

  In this special hit effect pattern group memory P1, a specific effect that is performed when the probability that a winning symbol is generated is set, and reach change and premium notice are set. This premium notice is a notice effect with a very low frequency of appearance, and when this effect is made, the probability that the lottery result in the change is successful is extremely high. By using such a specific effect, the player can grasp the probability that the stop symbol displayed after the change is a winning symbol, that is, the jackpot probability is high during the symbol variation display. The expectation to the jackpot of the player can be increased.

  The normal hit effect pattern group memory P2 is determined to be hit by the hit random number determination means 623, and when the stop symbol is determined to be a normal hit symbol other than the probable variation symbol (in this embodiment, an even number) in the winning symbol. Is a memory for storing a plurality of types of symbol effect patterns (ordinary hit effect patterns) from the start of the change of the symbol displayed on the symbol display device 20 to the stop of the symbol. It is also possible to set the above premium notice in the normal hit effect pattern group memory P2.

  The off-state effect pattern group memory P3 stores a plurality of types of symbol effect patterns (out-right effect patterns) selected when the winning random number determination means 623 determines that the off-random effect is determined to be off, from the start of symbol variation to the stop of the symbol. Memory.

  In the present embodiment, the effect pattern includes not only a series of symbol effect patterns from the start of symbol change to the stop of the symbol as described above, but also an input valid time for enabling the input operation of the operation switch 6, Various information is set such as the timing at which the operation valid lamp 6a is lit and blinked during execution of the effect pattern.

  The effect pattern selection unit 624c first selects any one of the effect pattern group memories P1 to P3 from the effect pattern group memory 624b based on the stop symbol determined by the stop symbol determination unit 624a. Next, one effect pattern is selected from the selected effect pattern group memory based on the effect random number acquired by the effect random number acquisition means 621c.

  The symbol control means 625 controls the symbol variation process in which a plurality of symbols are variably displayed on the symbol display device 20 and then stopped and displayed in a predetermined order based on the determination result by the hit random number determination means 623. . For example, in the present invention, when a game ball wins in the start winning opening 12 (that is, detected by the start opening winning detection device 12a), it is based on the effect pattern determined by the effect pattern selection means 624c in the symbol display device 20. After the symbol variation mode is displayed for a predetermined time, the stop symbol determined by the stop symbol determining means 624a is displayed in the order of the left symbol, the right symbol, and the middle symbol.

  The expectation level display control means 626 stops display after displaying the change of the symbol during the display of the change of the symbol on the symbol display device 20, for example, as shown in FIG. This is to perform display control of the symbols so that the expected degree that the combination of symbols to be won is winning (that is, the stop symbol becomes the winning symbol) is temporarily visible.

  The degree of expectation is configured to be displayed by each symbol. More specifically, it is displayed by a combination of numbers and characters drawn on the symbol, and in this embodiment, as shown in FIG. 6 (a), using the numbers drawn on the symbol, the percentage (the higher the degree of expectation, The displayed value goes up).

  Such expectation is set in advance in an expectation table as shown in FIG. The expectation level display control means 626 corresponds to the expected degree from the expectation level table according to the effect pattern selected by the effect pattern selection means 624c and a predetermined selection probability (based on the hit determination result by the hit random number determination means 623). A is read and display control is performed so that the read expectation degree A is temporarily visible on the symbol display device 20.

  In addition, the display method of an expectation degree is not limited to this embodiment, For example, as shown in FIG.6 (b), a star character is set and displayed by these combinations (in this example, As the degree of expectation increases, the number of black stars decreases and the number of white stars increases), or the number of visible symbols as shown in FIG. 6C (in this example, the higher the degree of expectation, the temporarily visible It is only necessary to be able to notify the degree of expectation so that the player can understand, for example, the number of symbols that can be increased).

  In addition, the expectation level display control means 626, on the condition that the predetermined time has passed without any input operation of the operation switch 6 from the start of the symbol variation, the symbol display device 20 during the symbol variation display, The display control of the symbol is performed so that the expectation degree that the combination of symbols stopped and displayed after the variable display becomes a win can be temporarily recognized.

  The special game executing means 70 is for executing a special game when the winning random number determining means 623 determines that the winning is successful (that is, the combination of symbols to be stopped is winning). Means 71, continuation determination means 72, and probability fluctuation transition determination means 73 are provided.

  The unit game execution means 71 is for performing a unit game during a special game, and includes a big prize opening drive means 711 and a unit game end determination means 712.

  The special prize opening driving means 711 is for operating the special prize opening driving device 13m so that the special prize opening 13 is opened to facilitate the winning of a game ball.

  The unit game end determination means 712 is for determining whether or not to end the unit game based on a preset unit game end condition.

  The continuation determination means 72 is for determining whether or not to end the special game based on a preset continuation condition.

  The probability fluctuation transition judging means 73 is for judging whether or not the probability fluctuation is executed after the end of the special game. In the present embodiment, it is determined whether or not the winning symbol displayed on the symbol display device 20 is a predetermined probability variation symbol (that is, a portion of the winning symbol).

  The high-probability game setting means 80 determines the probability of occurrence of a winning symbol after the end of the special game from a low probability to a high probability when the determination result is positive by the probability fluctuation transition determination means 73, that is, a probability variation symbol. This is for setting the probability lottery table so as to vary. For example, in addition to “0-200”, “201-1280” is added to the winning value referred to by the winning random number determination means 623 so that the winning symbol occurrence probability is higher than usual.

  The payout control means 90 is for performing control for paying out a prize ball from the prize ball payout device 45.

  Next, an outline of control in the present embodiment will be described with reference to flowcharts shown in FIGS.

  FIG. 8 is a main flowchart of the pachinko machine PM. The game control means 50 first performs the initial setting of the entire gaming machine in step S1, performs the normal game process in step S2 and the special game process in step S3, and then returns to the normal game process in step S2. This operation is repeated until the power is turned off. The normal game process in step S2 and the special game process in step S3 will be described later.

  FIG. 9 is a flowchart of the normal game process in step S2. In the normal game process S2, a winning opening prize checking process (step S20) for checking a winning at each winning opening and a special game transition determining process (step S21) for determining whether or not to shift a special game are executed. Then, this process is terminated.

  FIG. 10 is a flowchart of the winning opening winning check process in step S20. In the winning opening winning check process S20, first, when the winning of a game ball to any of the general winning openings 11 is detected by the general winning opening winning detection device 11a (step S201), the detection signal is sent to the game control means 50. The general winning flag is set (step S202). Based on this flag, the payout control means 90 outputs an operation signal to the prize ball payout device 45. Upon receiving this signal, the prize ball payout device 45 is activated, and a predetermined number (for example, for each winning ball) (for example, (10 balls) prize balls are dispensed from the prize ball dispensing device 45 to the ball tray 4. Note that the flag set here is reset as appropriate based on the winning ball motion. When a winning of a game ball at the start winning opening 12 is detected by the start opening winning detection device 12a (step S203), the detection signal is sent to the game control means 50 and a start winning flag is set (step S203). S204). Based on this flag, the payout control means 90 outputs an operation signal to the winning ball paying device 45. Upon receiving this signal, the winning ball paying device 45 is operated to respond to the winning ball to the start winning opening 12. A predetermined number (for example, five balls) of prize balls are paid out from the prize ball payout device 45 to the ball tray 4.

  When the above-described winning opening winning check process S20 is completed, a special game transition determination process S21 is executed next. 11 is a flowchart of the first stage of the special game transition determination process in step S21, FIG. 12 is a flowchart of the symbol element acquisition process of step S210, and FIG. 13 is a flowchart of the latter stage of the special game transition determination process in step S21 (continuing from FIG. 11). 14 is a preceding flowchart of the expectation level display process in step S400, and FIG. 15 is a subsequent flowchart of the expectation level display process in step S400.

  In the special game transition determination process S21, as shown in FIG. 11, first, a symbol element acquisition process S210 is performed.

  As shown in FIG. 12, the symbol element acquisition process S210 determines whether or not the start winning flag is on in order to confirm whether or not the start winning opening 12 has been won (step S211). If it is not on, this process is terminated, and if it is on, the start winning flag is turned off (step S212). Next, it is confirmed whether or not the number of reserved balls that have won the stored start winning opening 12 has reached the upper limit of storage (for example, 4) (step S213). If the number of reserved balls has reached the upper limit, the symbol element acquisition process S210 is terminated as it is. In step S 213, if the number of reserves has not reached the upper limit of storage and can be stored, the number of reserved balls (at this time) is stored in the reserved ball information storage unit 622. Subsequently, one holding ball lamp 30 is turned on (step S214), a winning random number is acquired by the winning random number acquisition unit 621a (step S215), and a stopping symbol random number is acquired by the stopping symbol random number acquiring unit 621b (step S216). The production random number is acquired by the production random number acquisition unit 621c (step S217), and the obtained random number is stored in the reservation ball information storage unit 622 in correspondence with the number n (n = 1, 2, 3, 4) of each reservation ball. The information is stored in the provided information storage area (step S218), and the symbol element acquisition process S210 is terminated.

  The special game transition determination process S21 returns to FIG. 11, and checks whether or not the reserved ball information is stored in the reserved ball information storage unit 622 (step S230). Here, when there is no storage of the holding ball, this processing is terminated, and when there is a storage of the holding ball, the information storage area (in the holding ball information storage unit 622) corresponding to the number n of the holding balls n = 1. The stored information is read (step S231), and the value of this information storage area is shifted (step S232). In step S231, the value A of the hit random number corresponding to the number n = 1 of the reserved balls is read as shown in FIG. 19A, and in the next step S222, the reserved balls are displayed as shown in FIG. 19B. The values B, C, and D stored in the information storage area corresponding to the number n = 2, 3, and 4 are shifted and stored in the information storage area corresponding to the number n-1 of the reserved balls.

  Then, the special game transition determination process S21 proceeds to step S233 shown in FIG. 13 and is read in the above-described step S231 (obtained for the oldest game ball stored in the reserved ball information storage unit 622). Based on the random number, the hit random number determination means 623 determines whether or not it is a win. Here, when it is determined that the winning symbol is a winning symbol, the predetermined symbol (that is, the winning symbol) is determined by the stopping symbol determining means 624a based on the stopping symbol random number read in step S231 (step S234). It is determined whether or not the winning symbol is a probability variation symbol (step S235). Here, when it is determined that the winning symbol is a probabilistic variation symbol, the special hit effect pattern group memory P1 is used by the effect pattern selection means 624c based on the stop symbol and the effect random number read in S231. A pattern is determined (step S236), and the process proceeds to step S240.

  On the other hand, if it is determined in step S235 that the winning symbol is not a probable variation symbol, the effect pattern selecting means 624c determines from the normal winning effect pattern group memory P2 based on the stop symbol and the effect random number read in S231. A normal winning effect pattern is determined (step S237), and the process proceeds to step S240.

  If it is determined in step S233 that the determination result of the winning random number is not winning, that is, it is determined that the winning random number is out of place, the stop symbol determining means 624a determines a predetermined value based on the stopping symbol random number read in step S231. A stop symbol, that is, a disjoint symbol is determined (step S238), and based on the stop symbol and the effect random number read in step S231, the effect pattern selecting means 624c determines a distraction effect pattern from the outlier effect pattern group memory P3 ( Step S239), the process proceeds to Step S240.

  In step S240, one holding ball lamp 30 is turned off, and a symbol variation process S250 and an expectation level display process S400 (see FIG. 14) described later are performed. These processes, that is, the symbol variation process S250 and the expectation level display process S400 are performed in parallel. Subsequently, whether or not the hit determination by the hit random number determination means 623 is a win in the above step S233 is confirmed (step S261). If the win determination is a win, the special game flag is turned on (step S262), and the process proceeds to step S263. On the other hand, if it is determined in step S261 that the hit determination by the hit random number determination means 623 is not a hit determination, that is, it is out of place (in step S233 described above), the process proceeds to step S263. In step S263, the information read in step S231 is erased, and this process ends.

  In the symbol variation processing S250, the effect pattern and the stop symbol acquired in the above steps are displayed on the symbol display device 20 by the symbol control means 625. Specifically, when the lottery result in step S233 is a win and the stop symbol is a probable variation symbol, the symbol display device 20 displays the variation of the symbol based on the special hit effect pattern, and then the left symbol, The right symbol and the middle symbol are stopped and displayed in this order, and the probability variation symbol (the combination of symbols per probability variation) is displayed. In addition, when the lottery result in step S233 is a win and the stop symbol is not a probable variation symbol, the symbol display device 20 displays the variation of the symbol based on the normal hit effect pattern, then the left symbol, the right symbol, and Stops and displays in the order of the middle symbols, and displays the normal winning symbol (the combination of symbols for normal winning). In addition, when the lottery result in step S233 is out and the stop symbol is out of symbol, the symbol display device 20 performs variable display of the symbol based on the off effect pattern, then the left symbol, right symbol, and middle symbol. The symbols are stopped and displayed in the order of symbols, and a missing symbol (combination of symbols to be removed) is displayed.

  The expectation level display process S400 is a process that is performed in parallel with the above-described symbol variation process S250, and is a process that is performed after the symbol variation display is started until it is stopped.

  In the expectation level display process S400, as shown in FIG. 14, first, it is determined whether or not it is time to permit an input operation of the operation switch 6 (step S401). However, the timing for permitting the input operation of the operation switch 6 is the game situation when a predetermined symbol is changing in the symbol changing process, for example, after the change display of all the left, right and middle symbols is started. The timing according to is preset. If it is determined that it is not time to allow the input operation of the operation switch 6, the process proceeds to step S405. On the other hand, if it is determined that it is time to permit the input operation of the operation switch 6, the operation valid lamp 6a is turned on to notify the player of that fact (step S402). Then, while the operation valid lamp 6a is lit, it is determined whether or not the operation detection device 6b has detected an input operation on the operation switch 6, that is, whether or not the player has performed an input operation on the operation switch 6 ( Step S403). Here, when it is determined that the input operation of the operation switch 6 has not been performed, it is determined whether or not a predetermined time (for example, 5 seconds) has elapsed since the operation valid lamp 6a was turned on (step S404). Here, when it is determined that the predetermined time has not elapsed, this processing is terminated. On the other hand, if it is determined in step S404 that the predetermined time has elapsed, the operation valid lamp 6a is turned off to indicate that the input operation of the operation switch 6 has been completed (step S405), and this process ends. . On the other hand, if it is determined in step S403 that the input operation of the operation switch 6 has been performed, the operation valid lamp 6a is turned off (step S406), and the effect pattern selected in the above step from the expectation level table (see FIG. 7). Then, the expectation degree A is read according to a predetermined selection probability (step S407), and the process proceeds to step S410.

  In step S410, it is determined by the symbol control means 625 whether or not the left symbol is variably displayed (that is, whether or not all symbols are variably displayed) in the variation (step S410). Here, if it is determined that the left symbol is being displayed in the variation, the expectation level A read in step S407 by the expectation level display control means 626 is displayed in 3 digits (step S411). End the process. If it is determined in step S410 that the left symbol is not being displayed in the variation, whether or not the right symbol is displayed in a variation by the symbol control means 625 (that is, the left symbol is displayed). It is determined whether or not the right symbol and the middle symbol are in a variable display state (step S412). Here, when it is determined that the right symbol is in the variation display in the variation, the expectation level A read in step S407 by the expectation level display control means 626 is displayed in two digits (step S413). Exit. If it is determined in step S412 that the right symbol is not being displayed in the variation, whether or not the middle symbol is being displayed in the variation by the symbol control means 625 (that is, the left symbol and the right symbol). It is determined whether or not the symbol is stopped and the middle symbol is in a variable display state (step S414). Here, if it is determined that the middle symbol is being displayed in the fluctuation state, the expectation degree A read in step S407 by the expectation degree display control means 626 is displayed in one digit (step S415). Exit. On the other hand, if it is determined in step 414 that the middle symbol is not in the variation display in the variation, that is, if it is determined that the display is stopped, this processing is terminated.

  Here, regarding the above-described expectation level display processing S400 (specifically, steps S410 to S415), examples of screens of FIGS. 20 and 21, FIGS. 22 and 23, FIGS. 24 and 25, FIGS. 26 and 27, FIGS. Five game examples will be described using a timing chart. However, the symbols shown at the bottom of the timing charts of FIGS. 21, 23, 25, 27 and 29 correspond to the figure numbers showing the screen examples of FIGS. 20, 22, 24, 26 and 28, respectively.

  20 and 21 show a case where the input operation of the operation switch 6 is performed once when all symbols are variably displayed in the variation, and FIGS. 22 and 23 show that the left symbol is stopped and displayed in the variation. FIG. 24 and FIG. 25 show the case where the input operation of the operation switch 6 is performed once when other symbols are variably displayed. FIGS. 24 and 25 show that the left symbol and the right symbol are stopped and the middle symbol is displayed in the variation. The case where the input operation of the operation switch 6 is performed once when the variation display is performed is shown. FIG. 26 and FIG. 27 show a case where the input operation of the operation switch 6 is not performed even once in the fluctuation. 28 and 29, in the variation, when all symbols are variably displayed, the input operation of the operation switch 6 is performed once, and then the left symbol is stopped and the other symbols are variably displayed. When the input operation of the operation switch 6 is performed once, and the input operation of the operation switch 6 is performed once when the left symbol and the right symbol are stopped and the middle symbol is variably displayed. Is shown.

  First, the case where the input operation of the operation switch 6 is performed once when all symbols are displayed in a variable manner in the fluctuation will be described with reference to FIGS. In this case, the timing for permitting the input operation in step S401 is from the start of the variable symbol display to the stop display. However, if there is an input operation of the operation switch 6 during this period, the permission of the input operation is terminated at that time.

  First, in the symbol display device 20, when the variable display of all the symbols on the left, right, and inside is started (see FIGS. 20 (a) and (b) and FIGS. 21 (a) and (b)), The operation enable lamp 6a of the operation switch 6 is turned on. When all the symbols are variably displayed in this way (when the lamp is lit), if there is an input operation of the operation switch 6, all symbols are temporarily stopped (visible to the player) The level of expectation is displayed in three digits (see the portions of FIGS. 20 (c) and 21 (c)). Here, FIG. 20C is an example in which the degree of expectation is represented by three-digit numbers “0”, “9”, and “5”, and the degree of expectation in the fluctuation is “95%”. This means that there is a high possibility that the stop symbol will be a winning symbol. Then, after the variable display of the symbols is resumed (see the portions in FIGS. 20D and 21D), the left symbols are first stopped and displayed (the portions in FIGS. 20E and 21E). Next, the right symbol is stopped and displayed (see the part (f) in FIG. 20 (f) and FIG. 21), and finally the middle symbol is stopped and displayed (FIG. 20 (g)). ) And FIG. 21 (g)).

  Next, a case where the input operation of the operation switch 6 is performed once when the left symbol is stopped and the other symbols are variably displayed in the variation will be described with reference to FIGS. In this case, the timing for permitting the input operation in step S401 is from the start of the variable symbol display to the stop display. However, if there is an input operation of the operation switch 6 during this period, the permission of the input operation is terminated at that time.

  First, in the symbol display device 20, when the variation display of all symbols is started (refer to FIGS. 22 (a) and (b) and FIGS. 23 (a) and (b)), the operation of the operation switch 6 is enabled. The lamp 6a is turned on, and the left symbol is first stopped and displayed (see the portions of FIGS. 22 (c) and 23 (c)). When the left symbol is stopped and the right symbol and the middle symbol are variably displayed in such a manner (the lamp is lit), if there is an input operation of the operation switch 6, the right and middle symbols are A temporary stop state (a state in which the player is stopped and displayed so as to be visible to the player) is temporarily displayed, and the expected degree is displayed in two digits (see the portions of FIGS. 22 (d) and 23 (d)). Here, FIG. 22D is an example in which the degree of expectation is expressed by two-digit numbers “9” and “5”, and the degree of expectation in the fluctuation is “95%”, that is, the stop symbol is hit. It means that the possibility of becoming a symbol is quite high. Then, after the variable display of the right and middle symbols is resumed (see the portions of FIGS. 22 (e) and 23 (e)), the right symbols are first stopped (FIGS. 22 (f) and 23 (f). )), And finally, the middle symbol is stopped and displayed (see the portions of FIG. 22 (g) and FIG. 23 (g)).

  Next, a case where the input operation of the operation switch 6 is performed once when the left symbol and the right symbol are stopped and the middle symbol is variably displayed will be described with reference to FIGS. 24 and 25. . In this case, the timing for permitting the input operation in step S401 is from the start of the variable symbol display to the stop display. However, if there is an input operation of the operation switch 6 during this period, the permission of the input operation is terminated at that time.

  First, in the symbol display device 20, when the variation display of all symbols is started (see FIGS. 24 (a), (b) and FIGS. 25 (a), (b)), the operation of the operation switch 6 is enabled. The lamp 6a is turned on, first the left symbol is stopped and displayed (see the portions of FIG. 24C and FIG. 25C), and then the right symbol is stopped and displayed (FIG. 24D and FIG. 25). see d)). In this way, if the input operation of the operation switch 6 is performed when the lamp is on and the left symbol and the right symbol are stopped and the middle symbol is variably displayed, the middle symbol is temporarily displayed. A temporary stop state (a state where the player is stopped and displayed so as to be visible to the player) is displayed, and the expected degree is displayed in one digit (see the portions of FIGS. 24 (e) and 25 (e)). Here, FIG. 24E is an example in which the degree of expectation is represented by a single-digit number of “9”, and the degree of expectation in the fluctuation is 90% or more, that is, there is a possibility that the stop symbol becomes a winning symbol. Means that it is quite expensive. Then, after the middle symbol variable display is resumed (see the part of FIG. 24 (f) and FIG. 25 (f)), the middle symbol is finally stopped and displayed (FIG. 24 (g)). And see the portion of FIG. 25 (g)).

  Next, the case where the input operation of the operation switch 6 is not performed once in the variation, that is, the case where only the display of the normal symbol variation process is performed will be described with reference to FIGS. 26 and 27. In this case, the timing for permitting the input operation in step S401 is from the start of the variable symbol display to the stop display. However, if there is an input operation of the operation switch 6 during this period, the permission of the input operation is terminated at that time.

  First, in the symbol display device 20, when the variation display of all symbols is started (see FIGS. 26 (a) and (b) and FIGS. 27 (a) and (b)), the operation of the operation switch 6 is enabled. The lamp 6a is turned on, first the left symbol is stopped and displayed (see the part of FIG. 26 (c) and FIG. 27 (c)), and then the right symbol is stopped and displayed (FIG. 26 (d) and FIG. 27 (d). )), And finally, the middle symbol is stopped and displayed (see FIGS. 26 (e) and 27 (e)). Note that, when there is no input operation of the operation switch 6 after the start of the symbol variation display, the operation valid lamp 6a is turned off after a predetermined time has elapsed, and the input operation of the operation switch 6 is not accepted.

  Next, using FIG. 28 and FIG. 29, when all the symbols are variably displayed in the variation, the input operation of the operation switch 6 is performed once, then the left symbol is stopped and the other symbols are displayed. The input operation of the operation switch 6 is performed once when the symbol is variably displayed, and when the left symbol and the right symbol are stopped and the middle symbol is variably displayed, the input operation of the operation switch 6 is 1 The case where it is performed once will be described. In this case, the timing for permitting the input operation in step S401 is from the start of the variable symbol display to the stop display. However, if there is an input operation of the operation switch 6 from the start of the change display of all symbols to the stop display of the left design, the right design stops after the start of the right / middle design change display. When there is an input operation of the operation switch 6 until it is displayed, and there is an input operation of the operation switch 6 after the middle symbol variation display is started until the middle symbol is stopped and displayed. In each case, the permission of the input operation is once ended.

  First, in the symbol display device 20, when the variable display of all the symbols on the left, right, and inside is started (see FIGS. 28 (a) and (b) and FIGS. 29 (a) and (b)), The operation enable lamp 6a of the operation switch 6 is turned on. As described above, when the input of the operation switch 6 is performed while the lamp is lit and all symbols are displayed in a variable manner, all symbols are temporarily stopped (visible to the player). The expectation is displayed in three digits (see the portions of FIG. 28 (c) and FIG. 29 (c)). FIG. 28C is an example in which the degree of expectation is represented by three-digit numbers “0”, “3”, and “0”, which means that the degree of expectation in the fluctuation is “30%”. doing.

  Subsequently, after the variable display of all symbols is resumed (see the portions in FIGS. 28 (d) and 29 (d)), the left symbol is stopped and displayed (see FIGS. 28 (e) and 29 (e)). The operation valid lamp 6a of the operation switch 6 is turned on. When the left symbol is stopped and the right symbol and the middle symbol are variably displayed in such a manner (the lamp is lit), if there is an input operation of the operation switch 6, the right and middle symbols are The temporary stop state (a state in which the player is stopped and displayed so as to be visible to the player) is temporarily displayed, and the expectation is displayed in two digits (see FIGS. 28 (f) and 29 (f)). Note that FIG. 28F is an example in which the degree of expectation is represented by two-digit numbers “5” and “0”, which means that the degree of expectation in the fluctuation is “50%”.

  Then, after the variable display of the right and middle symbols is resumed (see the portions of FIGS. 28 (g) and 29 (g)), the right symbols are stopped and displayed (FIGS. 28 (h) and 29 (h)). The operation valid lamp 6a of the operation switch 6 is turned on. When an input operation of the operation switch 6 is performed when the left symbol and the right symbol are stopped and the middle symbol is variably displayed (the lamp is lit), the middle symbol is temporarily displayed. Is in a temporarily stopped state (a state in which the player is stopped and displayed so as to be visible to the player), and the expected degree is displayed in one digit (see FIGS. 28 (i) and 29 (i)). FIG. 28 (i) is an example in which the degree of expectation is represented by a single-digit number “9”, which means that the degree of expectation in the fluctuation is 90% or more.

  Then, after the middle symbol variable display is resumed (see the part of FIG. 28 (j) and FIG. 29 (j)), the middle symbol is stopped and displayed (FIG. 28 (k) and FIG. 28). (See 29 (k)).

  As shown in FIGS. 28 (e) and (i), the present embodiment is configured to display the tenths of the ratio indicating the expected degree when the expected degree is represented by a single digit number. However, it is not limited to this. For example, it may be configured to display the first place of the ratio indicating the degree of expectation. When the ratio indicating the degree of expectation is 19%, 29%, 99%, the degree of expectation generally displayed on the symbol display device 20 Becomes “9”. In this case, since the player cannot distinguish whether the degree of expectation is “99%” or “9%”, the player's interest in the jackpot can be further increased. Moreover, you may comprise so that the high-order digit of the ratio which shows an expectation degree may be displayed. For example, when the degree of expectation is 19%, “1” may be displayed.

  Subsequently, special game processing S3 is performed. This special game process S3 is a process of establishing a special game that can execute a unit game a predetermined number of times (for example, 15 times) when the lottery result of the winning random number acquired in step S215 is winning. 16 is a preceding flowchart of the special game process S3, FIG. 17 is a subsequent flowchart of the special game process S3, and FIG. 18 is a flowchart of the special game end process S320.

  As shown in FIG. 16, it is confirmed whether or not the special game flag is turned on, that is, whether or not the acquired winning random number is winning (step S301). In the case of winning, a special game initial setting such as turning off the special game flag or changing to a normal low probability when the winning symbol occurrence probability is high is performed (step S302). Next, various initial settings for performing the unit game are performed (step S303), and the unit game is started.

  In the unit game, the special prize opening driving unit 711 operates the special prize opening driving device 13m to open the special prize opening 13 to start the first unit game. When the grand prize winning opening 13 is opened, the game ball moving in the game area space is in a state where it is very easy to win the big winning prize opening 13. In this state, when a game ball wins the big winning opening 13, a predetermined number (for example, 13) of winning balls are paid out to the ball receiving tray 4 by the payout control means 90. Yes.

  When such a unit game is started, the unit game end determination means 712 determines whether or not a unit game end condition described below is achieved. Until the unit game end condition is achieved, the opening operation of the special winning opening 13 is continued.

  As a unit game end condition, “number of winning balls” and “time limit” are set as requirements. The requirement for the “number of winning balls” is that it is determined that the unit game end condition has been achieved when the total number of game balls won in the grand prize opening 13 reaches a predetermined number (for example, 10 balls). is there. The requirement for “opening time” is that when the opening time of the special winning opening 13 after the start of the unit game has passed a predetermined time (for example, 30 seconds), it is determined that the unit game end condition has been achieved. It is to do.

  In the special game process S3, whether or not the above-mentioned unit game end condition is achieved is advanced as shown in FIG. First, it is determined (following step S303) whether or not the big prize opening 13 is won by the big prize opening detection device 13a (step S304). Here, if it is determined that the big prize opening 13 has not been won, the process proceeds to step S306. On the other hand, if it is determined that the winning prize opening 13 has been won, the winnings necessary for the completion of the preset unit game conditions are determined from the winning ball counter (not shown) attached to the winning prize opening 13. 1 is reduced from the number of balls (for example, 10 balls) (step S305), and the process proceeds to step S306. In step S306, the specific area passage detection device 13b determines whether or not a game ball has won a specific area (not shown). Here, if it is determined that the specific area has not been won, the process proceeds to step S308. On the other hand, if it is determined that a prize has been won in the specific area, a specific area flag is set (step S307), and the process proceeds to step S308. In step S308, it is determined whether or not the number of winning balls in the special winning opening 13 has reached a predetermined number (for example, 10 balls) (step S308). Here, if the number of winning balls in the special winning opening 13 satisfies a predetermined number, the unit game end condition is achieved, and the process proceeds to step S310. On the other hand, if the number of winning balls in the special winning opening 13 does not satisfy the predetermined number, the process proceeds to step S309. In step S309, it is determined whether or not the opening time, which is another unit end condition, has been reached. If it is determined that the release time has not ended (that is, the unit game end condition is not satisfied), the process returns to step S304 and the next unit game is played. On the other hand, if it is determined that the release time has ended (that is, the unit game end condition is satisfied), the process proceeds to step S310.

  As described above, when one of the conditions “number of winning balls” or “time limit” is satisfied, the unit game end determination means 712 determines that the unit game end condition has been achieved, and ends the unit game. Let

  When the unit game end condition as described above is achieved, the opening of the special winning opening 13 is stopped, and it is determined whether or not the continuation determination condition is achieved by the continuation determination means 72 (step S310). The continuation condition is a condition that whether or not a game ball is won in a specific area during a unit game and a specific area flag is set. In addition, the achievement of the continuation condition is a case where there is a winning in a specific area during the unit game. In step S310, if it is not determined that the continuation condition has been achieved, that is, if the unit game ends without winning a specific area, a special game end process S320 is performed.

  On the other hand, if it is determined in step S310 that the continuation condition has been achieved, that is, if there is at least one winning ball in the specific area during the current unit game, the specific area flag is turned off (step S311). Then, in order to count the number of rounds of the unit game after starting the current special game, 1 is decremented from a counter set in advance (for example, 15 times) (step S312). Subsequently, it is determined whether or not the counter of the number of rounds has become less than 0, that is, whether or not the number of unit games has been repeated a predetermined number of times (step S313). Here, when the counter of the number of rounds is not less than 0, that is, when it has not been repeated a predetermined number of times, the process returns to step S303 and the next unit game is performed. When the round number counter is less than 0, that is, when the unit game is repeated a predetermined number of times, the process proceeds from step S313 to the special game end process S320.

  The special game end process S320 is shown in FIG. 18, and first, the probability variation transition determining means 73 determines whether or not the stopped symbol at the time of winning is a probability variation symbol (step S321). Here, if it is determined that the symbol is a probability variation symbol, the probability variation lottery table in which the winning value is set by the high probability game setting means 80 so that the probability of the symbol occurrence is higher than usual (step) S322). The probability lottery table is reset as appropriate in step S302. Subsequently, the probability variation winning screen is displayed on the symbol display device 20 (step S323). In this probability variation winning screen, for example, the word “probability variation” is displayed in a large size so that the player can easily grasp that the winning symbol occurrence probability has fluctuated with a high probability. This is a screen display mode. On the other hand, if it is determined in step S321 that the stop symbol is not a probability variation symbol, a notification is given on the probability variation non-winning screen (step S324). Note that the probability variation non-winning screen is a screen display in which characters such as “Zanen” are displayed in a large size in order to inform the player that the probability of occurrence of the winning symbol remains normal and does not become high. It is an aspect.

  In addition, this invention is not limited to the said Example, If it is a range which does not deviate from the summary of this invention, it can improve suitably.

  For example, in the expectation level display process S400, the original expectation level may be displayed as the input operation of the operation switch 6 is performed in one symbol variation process. Specifically, when the original reliability is 88%, the display corresponding to the first input operation is “50%”, the display corresponding to the second input operation is “80%”, and the third time The display according to the input operation may be configured as “88%” so as to increase the player's expectation. In this case, when the input operation in step S401 is permitted, the input operation is performed when there is an input operation of the operation switch 6 from the start of the change display of all symbols to the stop display. The input operation of the operation switch 6 is permitted again when a predetermined time elapses later.

  In the expectation level display process S400, as shown in FIG. 30, it is possible to multiply the original expectation level by a predetermined coefficient to create various gaming situations. Specifically, after the process proceeds to step S407 (see FIG. 14) in the above-described expectation level display process S400, the process proceeds to step 420 shown in FIG. 30, where a random number Z is first acquired, It is determined whether or not the left symbol is variably displayed (that is, whether or not all symbols are variably displayed) (step S421). Here, when it is determined that the left symbol is being displayed in the variation, the expectation A read in step S407 is multiplied by the random number Z obtained in step S420 and the coefficient 0.8. The display expectation degree A ′ is obtained (step S422). Then, the display expectation degree A ′ is rounded (step S423), the rounding display expectation degree A ′ is displayed in three digits (step S424), and this process is terminated. .

  If it is determined in step S421 that the left symbol is not being displayed in the variation, whether the right symbol is being displayed in the variation by the symbol control means 625 (that is, the left symbol is Whether the right symbol and the middle symbol are in a variable display state is determined (step S425). Here, when it is determined that the right symbol is being displayed in the variation, the expectation A read in step S407 is multiplied by the random number Z obtained in step S420 and the coefficient 0.9. The display expectation degree A ′ is obtained (step S426). Then, the decimal point of the display expectation degree A ′ is rounded (step S427), the display expectation degree A ′ subjected to the rounding process is displayed in two digits (step S428), and this process is terminated. .

  If it is determined in step S425 that the right symbol is not being displayed in the variation, whether or not the middle symbol is displayed in the variation by the symbol control means 625 (that is, the left symbol and the right symbol). It is determined whether or not the symbol is stopped and displayed, and the middle symbol is in the variable display state (step S429). Here, when it is determined that the right symbol is being displayed in the variation, the expectation A read in step S407 is multiplied by the random number Z obtained in step S420 and the coefficient 0.9. The display expectation degree A ′ is obtained (step S430). Then, the display expectation degree A ′ is rounded (step S431), the display expectation degree A ′ subjected to the rounding process is displayed in one digit (step S432), and this process is terminated. .

  In the above case, the timing for permitting the input operation in step S401 is from the start of the display of all symbols to the time of stop display. However, if there is an input operation of the operation switch 6 during this period, the permission of the input operation is terminated at that time.

  Further, the coefficients (0.8, 0.9, and 1.0 in this example) to be multiplied by the expectation degree A can be set as appropriate. Further, the rounding process of the decimal point performed in steps S423, S427, and S432 is a process of rounding off or rounding off the decimal point to obtain a number that can be displayed on the symbol display device 20. For example, when the reliability is “62.5% (0.625)”, the decimal part is rounded off and “63 (%)” is displayed on the symbol display device 20. In step S432, the degree of expectation is indicated by one digit. However, this may be either a tens digit of the expectation A ′ or a number of the first digit.
