Description

  The present invention relates to a ball game machine represented by a pachinko machine, and more particularly to a ball game machine that performs a special game when a symbol displayed on a symbol display device becomes a preset symbol.

  In conventional ball game machines such as pachinko machines, it is generally known that a symbol display device such as a liquid crystal display is provided at the center of the game board constituting the game area, and the start provided in the game area When a game ball wins in a winning opening, a combination of symbols (hereinafter referred to as stop symbols) when a symbol is displayed in a stopped state after a plurality of symbols are variably displayed on the symbol display device (hereinafter referred to as stop symbols) In the case of a winning symbol), a special gaming state (a big winning state) is established. In the special gaming state, the variable winning opening (large winning opening) provided at the lower part of the gaming area is opened to facilitate the winning of the game ball, so that the player can acquire a large number of game balls. Yes.

  By the way, in the ball ball game machine having the above-described configuration, during the symbol variation display, the expectation that the symbol that is stopped and displayed after the symbol variation display becomes a winning symbol (that is, the possibility of being a big hit) Some of them are displayed on a probability display provided in the game area (see, for example, Patent Document 1). With such a configuration, the degree of expectation in the variation can be notified, and the player can be given a sense of expectation for jackpot.

JP 2001-54649 A

  However, in the gaming machine described in Patent Literature 1, since the expected degree once displayed is not changed until the change is completed, the player can generate a big hit after the change when the low expected degree is displayed. It was found that there was almost no sex, and there was a risk that the player's enjoyment of the game was impaired.

  The present invention has been made in view of such a problem, and during the display of the variation of the symbol, the expectation that the symbol that is stopped and displayed after the variation display of the symbol is a winning symbol is changed and displayed for each input operation of the player. It is an object of the present invention to provide a ball game machine that allows players to actively participate in a game and keep expectation for jackpots during the symbol variation process.

  In order to achieve such an object, the present invention provides a symbol display device capable of displaying symbol variation, and a lottery for performing a lottery on whether or not to execute a special game on the condition that a game ball has won a winning prize opening. A symbol change that causes a plurality of symbols to be variably displayed on the symbol display device based on a lottery result by means (for example, symbol element acquisition unit 621, winning random number determination unit 623 in the present embodiment) and the lottery unit, and then stops display. When the symbol control means for controlling the process and a combination of the symbols that are stopped and displayed by the symbol control means are predetermined winning symbols, a variable prize opening provided in the game area (for example, In a gaming machine provided with special game execution means for performing a special game that makes it easy to win a prize winning opening 13) in the present embodiment, the change of the symbol is displayed during the symbol variation display. Expected degree display control means for displaying the expected degree that the combination of symbols stopped and displayed after the display is won on a predetermined display unit, and operating means that can be input by the player (for example, the operation switch in the present embodiment) 6) and an expectation degree table in which a plurality of initial values and upper limit values of the expectation degrees corresponding to the lottery result are set. In addition, the expectation level display control means selects the corresponding expectation level from the expectation level table based on the lottery result when the symbol change display is being performed and the operation means is input. Each time the operating means is input during display of variation of the symbol, the expectation is changed and displayed within a range from the initial value to the upper limit value.

  In the ball game machine having the above-described configuration, the expectation level display control unit sets the initial value of the selected expectation level when the input operation of the operation unit is the first input operation during the symbol variation display. After that, each time the operation means is input during display of the change of the symbol, the expectation degree is changed and displayed so as to gradually increase within the range from the initial value to the upper limit value. It is preferable.

  Further, in the ball ball game machine having the above-described configuration, the expectation table includes an input of the operation means within a range from the initial value to the upper limit value in each of the plurality of expectation degrees according to the lottery result. A plurality of values corresponding to the number of operations are set, and the expectation level display control unit is configured to display a value corresponding to the number of input operations of the operation unit at the selected expectation level. preferable.

  According to the present invention, it is possible to change the expectation degree that the symbol that is stopped and displayed after the symbol variation display during the symbol variation display becomes a symbol and change display for each player's input operation. Once the low expectation is displayed, the player's interest is likely to be lessened during the symbol change process (ie, from the start of the symbol change display until it is stopped). It is possible to provide a ball and ball game machine that allows a player to actively participate in a game and keeps the player expected to win a jackpot.

  Note that when the operating means is input and this is the first input operation during the symbol variation display, the initial value of the expectation is first displayed, and then the manipulation means is input during the symbol variation display. It is preferable that the degree of expectation is changed and displayed so as to increase gradually every time. According to such a structure, the degree of expectation increased for each player's input operation is displayed. Even if the degree of expectation is displayed, the player can be concentrated in the game without reducing the player's interest, and the expectation for the jackpot can be enhanced.

  In addition, a plurality of expectation levels corresponding to the lottery results are set, and a plurality of values corresponding to the number of operation inputs of the operation means are set for each of the expectation levels. It is preferable that the expectation level corresponding to the above is displayed, and according to such a configuration, the expectation level is changed and displayed according to the number of input operations of the player. Can continue to give a sense of expectation for jackpots.

  The operation switch 6 that can be pressed is provided with an operation effective lamp 6a (a portion indicated by hatching in FIG. 1) constituted by an LED or the like. The operation valid lamp 6a notifies the player by lighting or flashing that the input (pressing) operation of the operation switch 6 is valid. In the present embodiment, the player is notified that the input (pressing) operation of the operation switch 6 is effective by turning on the operation effective lamp 6a.

  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. Moreover, when a hit ball wins the start winning opening 12 out of the winning openings 11 and 12 described above, 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. After a predetermined time has elapsed, the display is stopped. In the case of a combination of symbols in which the symbol displayed in a stopped manner is a predetermined winning combination (for example, 1 to 9), a big winning opening that has become a big hit and has become easy to win. When a hit ball is won in 13, a large amount of award balls are paid out to the player.

  In the present embodiment, the operation valid lamp 6a is lit during the symbol variation display (however, the expectation is being displayed, except at the start and end of the symbol variation process), and the operation switch 6 is input by the player. Each time the operation is performed, the symbol display device 20 is configured to temporarily stop and display the symbol, and the degree of expectation in the variation is temporarily visible.

  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 hit symbol occurrence probability changes is set, and reach change and premium notice are set. Note that the premium notice is a notice effect with a very low frequency of occurrence, and when this effect is made, the probability that the lottery result in the change is a win 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.

  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), the effect display unit 20 determines the effect pattern determined by the effect pattern selection means 624c. Based on this, the symbol variation mode is displayed for a predetermined time, and then the stop symbols determined by the stop symbol determining means 624a are displayed in the order of the left symbol, the right symbol, and the middle symbol.

  The expectation level display control means 626 displays the expected degree of winning the combination of symbols that are stopped and displayed after the change display of the relevant symbol during the symbol change display (that is, the stop symbol becomes the winning symbol). It is intended for display. In the present embodiment, the expectation level display control means 626 changes and displays the expectation level every time the operation switch 6 is input by the player. Further, the expectation level display control means 626 displays the expectation level by causing the symbol display device 20 to display (temporarily stop) the symbol that is being variably displayed while swinging to the extent that it can be visually recognized by the player.

  The degree of expectation is displayed as a symbol used in the symbol display device 20 (specifically, as shown in FIGS. 6A to 6C, a combination of characters such as numbers 0 to 9 and stars). The number of symbols). In the present embodiment shown below, the numbers 0 to 9 drawn on the symbol are used as percentages (the higher the degree of expectation, the higher the displayed numerical value) (see FIG. 6A).

  However, the method of displaying the degree of expectation is not limited to this embodiment. For example, as shown in FIG. 6B, a star character is set and displayed in a combination thereof (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 more temporarily 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 visually recognized is increased).

  Such an expectation degree is set in advance in an expectation degree table as shown in FIG. 7, and the expectation degree display control means 626, as will be described in detail later, is an effect pattern selected by the effect pattern selection means 624c and ( In accordance with a predetermined selection probability (based on the hit determination result by the hit random number determination means 623), the corresponding expectation A is read from the expectation degree table, and the read expectation A is temporarily stored in the symbol display device 20. The display is controlled so as to be visible.

  Note that the degree of expectation does not necessarily need to be read from the degree-of-expectation table as shown in FIG. 7, and may be calculated from a predetermined formula every time the operation switch 6 is input as described later (see FIG. 26). .

  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 game 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 game transition judging means 73 is for judging whether or not the probability variation is executed after the special game is finished. 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, when the probability game transition determination means 73 determines that the determination result is affirmative, that is, a probability variation symbol, the probability of winning the winning symbol after the end of the special game is low to high probability 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 the control in the present embodiment will be described with reference to the 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 flowchart of the preceding stage of the expectation level display process of Step S400, FIG. 15 is a flowchart of the input timing determination process of Step S410, FIG. 16 is a middle stage flowchart of the expectation level display process of Step S400, and FIG. It is a back | latter stage flowchart.

  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. 21A, and in the next step S232, the reserved balls are displayed as shown in FIG. 21B. 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 the symbol variation process S250 and the expectation level display process S400 (see FIGS. 14 to 17) are performed in parallel (these processes will be described later). 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.

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

  As shown in FIG. 14, in the expectation level display process S400, first, an input timing determination process is performed to determine whether or not it is a timing to permit an input operation of the operation switch 6 (step S410).

  As shown in FIG. 15, the input timing determination process S410 confirms whether or not the current gaming state is displaying a change in symbol (step S411). Here, when the symbol variation display is not being performed, this processing is terminated. On the other hand, if it is confirmed in step 411 that the symbol is changing, it is determined whether or not the expectation A is being displayed (step S412). Here, when it is determined that the expectation degree A is being displayed, this processing is terminated. On the other hand, if it is determined in step S412, that the expected degree A is not being displayed, the remaining time until the symbol is stopped and displayed in the fluctuation is longer than the time necessary for displaying the expected degree A once. It is determined whether there are many (step S413). Here, when it is determined that the remaining time until the symbol is stopped and displayed in the variation is less than the time required to display the expectation degree A once, this processing is terminated. On the other hand, if it is determined in step S413 that the remaining time until the symbol is stopped and displayed in the variation is longer than the time required to display the expectation degree A once, the input permission flag is set. (Step S414), and this process is terminated.

  Following the input timing determination process S410, the expectation level display process S400 determines whether or not the input permission flag is on as shown in FIG. 14 (step S420). Here, if it is determined that the input permission flag is not on, that is, it is not the timing to permit the input operation of the operation switch 6, the process proceeds to step S424. On the other hand, if it is determined in step S420 that the input permission flag is ON, that is, 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 to that effect. (Step S421). 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 S422). 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 is turned on (step S423). 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 S423 that the predetermined time has elapsed, the operation valid lamp 6a is turned off to indicate that the acceptance of the input operation of the operation switch 6 has been completed (step S424), and this process ends. To do. On the other hand, if it is determined in step S422 that the input operation of the operation switch 6 has been performed, the operation valid lamp 6a is turned off (step S425), and the input permission flag is turned off (step S426).

Subsequently, in the expectation level display process S400, an expectation level that is changed and displayed every time there is an input operation of the operation switch 6 is obtained. Below, the case where the expectation degree displayed on the symbol display apparatus 20 is incremented by 1 for each input operation of the operation switch 6 will be described. As shown in FIG. 16A, first, it is determined whether or not the current input operation of the operation switch 6 is the first input operation in the fluctuation (step S430). Here, when it is determined that the input operation is the first time, the expectation degree A (= initial value A ₀₎ according to the effect pattern selected in the above step and a predetermined selection probability from the expectation degree table (see FIG. 7). ) (Step S431), and the process proceeds to step S460. On the other hand, if it is determined in step S430 that the input operation is not the first time, 1 is added to the current expectation A (step S432), and the process proceeds to step S460.

  Here, the above steps (S430 to S432) will be described with reference to a screen example. For example, when “40” is displayed as an expected degree on the symbol display device 20 after the first input operation in the change (FIG. 22). (See (a)), the expected level displayed after the subsequent second input operation is incremented by 1 to the expected level displayed at the first time to “41” (see FIG. 22B), and after the third input operation. The expected degree displayed is obtained by adding 1 to the expected degree displayed for the second time and “42” (see FIG. 22C)...

Subsequently, the process proceeds to step S460 shown in FIG. 17, and an allowable range of the upper limit value A _MAX is read from the expectation degree table shown in FIG. 7 in accordance with the effect pattern selected in the above step and a predetermined selection probability. A random number lottery is performed so as to be within the range, and a specific value of the upper limit value A _MAX is determined.

Here, with respect to step S460, taking a specific example with reference to FIG. 7, when the off effect pattern a is selected, it falls within the range of “40% to 50%” stored in the expectation degree table. The random number lottery is performed, and the upper limit value A _MAX is determined to a value of “47%”, for example.

Then, it is determined whether or not the expectation A is equal to or less than the upper limit value A _MAX determined as described above (step S461). Here, when it is determined that the expected degree A is equal to or lower than the upper limit value A _MAX , the expected degree A is set as the expected degree to be displayed on the symbol display device 20 (step S462), and the process proceeds to step S464. On the other hand, if it is determined in step S461 that the expected degree A is not less than or equal to the upper limit value A _MAX , that is, the expected degree A exceeds the upper limit value A _MAX , the upper limit is set as the expected degree to be displayed on the symbol display device 20. The value A _MAX is set (step S463), and the process proceeds to step S464.

In step S464, it is determined whether or not the symbol control means 625 is displaying the left symbol in the variation, that is, whether or not all symbols are in the variation display state as shown in FIG. To do. Here, when it is determined that the left symbol is in the variable display in the change, as shown in FIG. 23 (c), the expectation level (specifically, set in the above step by the expectation level display control means 626). In step S462, the expectation level A set in step S462 or the upper limit value A _MAX set in step S463) is displayed in three digits (step S465), and the process is terminated.

If it is determined in step S464 that the left symbol is not in the variation display in the variation, whether or not the right symbol is in the variation display by the symbol control means 625 in the variation, that is, FIG. As shown in e), the left symbol is stopped and displayed, and it is determined whether the right symbol and the middle symbol are in the variable display state (step S466). Here, when it is determined that the right symbol is being displayed in the variation, the expectation level (specifically, set in the above step by the expectation level display control means 626 is shown in FIG. 23 (f). Displays the expectation level A set in step S462 or the upper limit value A _MAX set in step S463) in two digits (step S467), and the process ends.

If it is determined in step S466 that the right symbol is not in the variation display in the variation, whether or not the middle symbol is in the variation display by the symbol control means 625 in the variation, that is, FIG. ), The left symbol and the right symbol are stopped and displayed, and it is determined whether or not the middle symbol is in the variable display state (step S468). Here, when it is determined that the middle symbol is in the variable display in the change, as shown in FIG. 23 (i), the expectation level (specifically, set in the above step by the expectation level display control means 626). Displays one of the expected degree A set in step S462 and the upper limit value A _MAX set in step S463) (step S469), and ends this process. On the other hand, if it is determined in step S468 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.

  Next, the three-digit display (see step S465), the two-digit display (see step S467), and the single-digit display (see step S469) of the expectation performed in the expectation display processing S400 will be described with reference to FIGS. 24 will be described. FIGS. 23 and 24 are screen examples and timing charts. When all symbols are variably displayed in one symbol variation process, the left symbol is stopped and other symbols are 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 performed. Note that the symbols shown at the bottom of the timing chart in FIG. 24 correspond to the figure numbers in the screen example in FIG.

  In the symbol display device 20, first, when the variable display of all the symbols on the left, right and inside is started (see FIGS. 23 (a) and (b) and FIGS. 24 (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. 23 (c) and FIG. 24 (c)). Then, all the symbols are displayed again (see the portions of FIGS. 23D and 24D), and the operation valid lamp 6a of the operation switch 6 is turned on. FIG. 23C is an example in which the degree of expectation is represented by three-digit numbers “0”, “8”, and “8”, and the degree of expectation displayed for the first time in the fluctuation is “88%”. "Means.

  After resuming the variable display of all the symbols as described above, the left symbol is then stopped and displayed (see the portions of FIGS. 23 (e) and 24 (e)). Here, when the operation valid lamp 6a of the operation switch 6 is lit, and the left symbol is stopped and the right symbol and the middle symbol are variably displayed, there is an input operation of the operation switch 6. The right and middle symbols are temporarily stopped (displayed while swinging to the extent visible to the player), and the expectation is displayed in two digits (FIGS. 23 (f) and 24 (f)). See section). Then, the right and middle symbols are displayed again (see the portions in FIGS. 23 (g) and 24 (g)), and the operation valid lamp 6a of the operation switch 6 is turned on. FIG. 23 (f) is an example in which the degree of expectation is represented by a two-digit number such as “8” and “9”, and the degree of expectation displayed for the second time in the change is (the value displayed for the first time). 1 is added to the degree of expectation), which means “89%”.

  After resuming the change display of the right and middle symbols as described above, the right symbol is then stopped and displayed (see the portions of FIGS. 23 (h) and 24 (h)). Here, when the operation valid lamp 6a of the operation switch 6 is lit, and 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 performed. Indicates that the middle symbol is temporarily suspended (displayed while swinging to the extent visible to the player) and the expectation is displayed in one digit (parts of FIG. 23 (i) and FIG. 24 (i)). See). FIG. 23 (i) is an example in which the degree of expectation is represented by a single-digit number of “9”, and the degree of expectation displayed for the third time in the change is (the degree of expectation displayed for the second time is 1 This means that it is “90% or more”.

  After resuming the middle symbol variation display as described above (see FIG. 23 (j) and FIG. 24 (j)), the middle symbol is stopped and displayed (FIG. 23 (k) and FIG. 24 (k)). See section). If the time necessary for displaying the expected degree remains after the variable symbol display is resumed, the operation valid lamp 6a of the operation switch 6 is lit. The lamp 6a is not lit (even during the symbol variation display).

  In the present embodiment, as shown in FIG. 23 (i), when the degree of expectation is represented by a single digit number, the tenth place of the degree of expectation is configured to display a number, but the present invention is not limited to this. It is not something. 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%, or 99%, the degree of expectation displayed on the symbol display device 20 as a whole. Becomes “9”. In this case, since the player cannot distinguish whether the degree of expectation is “99%” or “9%”, the player's sense of expectation for the jackpot can be further increased.

  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. 18 is a preceding flowchart of the special game process S3, FIG. 19 is a subsequent flowchart of the special game process S3, and FIG. 20 is a flowchart of the special game end process S320.

  As shown in FIG. 18, it is confirmed whether or not the special game flag is 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 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 1, 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 1, 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 1, 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. 20, and first, the probability game transition determination means 73 determines whether or not the stop 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). This 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 made 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 said embodiment, If it is a range which does not deviate from the summary of this invention, it can improve suitably.

  For example, in the present embodiment, the degree of expectation is displayed on the symbol display device. However, a probability indicator 40 (see FIG. 3) may be provided separately from this and the degree of expectation may be displayed. In addition, when displaying the degree of expectation on the probability display 40, it is the same as described above. That is, the expectation degree is changed and displayed on the probability display 40 every time the input operation of the operation switch 6 is performed until the stop display is performed after the symbol change display on the symbol display device 20.

  Further, in the above-described expectation level display process S400, the case has been described where the expectation level displayed on the symbol display device 20 is incremented by 1 for each input operation of the operation switch 6, but the present invention is not limited to this. . For example, as shown in FIG. 25, an expected degree corresponding to the number of input operations of the operation switch 6 is stored in advance in a table, and an expected degree corresponding to each input operation of the operation switch 6 is read out from here. You may comprise so that it may display on the display apparatus 20 (it can visually recognize temporarily).

  More specifically, after the process proceeds to step S426 in the expectation level display process S400, as shown in FIG. 16B, how many times the input operation of the current operation switch 6 is the input operation in the variation. After confirming (step S440), the degree of expectation corresponding to the number of input operations is read from the table shown in FIG. 25 (step S441), and the process proceeds to step S460 (see FIG. 17).

  This step will be described using a screen example. When the pattern p is selected from the table shown in FIG. 25 in this change, the expected degree A displayed after the first input operation of the operation switch 6 is 50 ( (See FIG. 25A.) Expected degree A displayed after the second input operation is 60 (see FIG. 25B). Expected degree A displayed after the third input operation is 70 (FIG. 25C). In this way, the expectation is changed and displayed for each input operation of the operation switch 6.

  Also, in the expectation level display process S400, a calculation formula for obtaining the expectation level is prepared in advance, and for each input operation of the operation switch 6, the values and signs of the terms constituting this calculation formula are determined by lottery. The degree of expectation A may be derived using the value and the sign, and displayed on the symbol display device 20 (so as to be temporarily visible).

  Here, as shown in FIG. 26, in order to obtain the degree of expectation A, a calculation formula including “x”, a sign “+” or “−”, and “y” is prepared, and the input of the operation switch 6 is performed. For each operation, the values of “x” and “y” are determined by random lottery or the like, and one of the signs “+” and “−” is selected and determined, and these determined values and signs are used (ie, The case where the degree of expectation A is calculated (using either A = x + y or A = xy) will be described.

  After proceeding to step S426 in the above-described expectation level display process S400, the process proceeds to step 450 shown in FIG. 16C. First, the value of “x” is determined by random number lottery, and the sign “+” or “−” is displayed. Is selected (step S451), and the value of “y” is determined by random number lottery (step S452). Then, the expectation degree A is calculated using these values and signs (step S453), and the process proceeds to the above-described step S460 (see FIG. 17).

  This step will be described with reference to a screen example. When x is 40, the sign is +, and y is 3 in the first input operation of the operation switch 6, the calculation formula A = Based on x + y = 40 + 3, the expected degree A to be displayed is 43 (see FIG. 26A), and the calculation is performed when x is 75, the sign is −, and y is 8 at the second input operation. Based on the formula A = xy = 75-8, the displayed expectation A is 67 (see FIG. 26B), and x is 68, the sign is +, and y is 20 in the third input operation. Is determined based on the calculation formula A = x + y = 68 + 20, the expected degree A to be displayed is 88 (see FIG. 26C), and the expected degree is changed for each input operation of the operation switch 6. The configuration is displayed. However, when the value of the expected value A calculated by the calculation formula becomes 0 or less, the displayed expected degree A is 0.

  Note that the calculation formula for obtaining the expectation degree A is not limited to the above, and can be set as appropriate, for example, by increasing the number of terms constituting the formula or by increasing / decreasing the types of codes to be used.
