Abstract

PROBLEM TO BE SOLVED: To make a sense of anticipation continue without allowing a game player to predict a progress of a game full of variety by making it barely possible to discern what type of winning.SOLUTION: By a game ball's winning entrance in a start port 8 as a trigger, a control is executed, in the control a presentation symbol 15 being variably displayed in a display device 4 to be stop displayed after an elapse of a prescribed time. As a result of a winning/losing lottery by a main control part, if a big win (a "probability variation winning") or a small win (a "non-probability-variation winning") are won, a game participation type presentation in which its display state changes on the basis of an operation to a game intervention operation part 7 is displayed in the display device 4. While this display is being executed, the result of the winning/losing lottery is being reported by a display of a special symbol in a special symbol display part 41.

Description

  The present invention relates to a gaming machine in which a winning / exit lottery is executed with a predetermined probability when a game ball enters a starting port provided on a game board surface.

  In game machines, in particular pachinko machines, a start opening that allows a game ball to enter the game board surface, and an internal lottery that is executed based on a predetermined probability triggered by the game ball entering the start opening ( Outside lottery (lottery of winning or not) and probability variation lottery (if the result of this / outside lottery wins, whether the probability of lottery in the normal gaming state after winning process is high probability, A lottery that decides whether or not to keep the normal probability)) results display to the player by effect display (effect display that displays a variety of effect symbols composed of numbers, chance symbols, etc., and stops display after a predetermined time) It has a display device for notification, a special symbol display section for notifying the player of the actual result of the internal lottery, and a large winning opening where a large amount of game balls can be won, and winning of the winning / external lottery There are several types of big hits and one type of small Or bets there are those that are set (for example, see Patent Document 1).

  As a result of the internal lottery, for example, in the case of winning the big hit A among the plural types of winning combinations, the display design is displayed in a variable manner on the display device, and finally, the display pattern in which the stop symbol of the production design is predetermined (For example, “1, 1, 1”), the special display unit is informed of the results of the jackpot and the probability variation lottery, and the big winning opening is opened for a predetermined time and a predetermined number of times to increase the winning rate of the game ball, A hit process for bringing the player into an advantageous state is executed, and a predetermined game value is given to the player. Further, for example, when winning a big hit B or a small hit, whether the big hit B or the small hit, the stop symbols of the production symbols are displayed in a predetermined display mode (for example, chance symbols in three rows). In the case of big hit B, the game value given to the player at the time of hit processing is low, but it is high in the normal game state after the hit processing. Probability is promised. In addition, in the case of a small hit, it is the same as the stop symbol of the effect symbol in the big hit B, but the game value given to the player at the time of the hit processing is low, and the high probability also in the normal game state after the hit processing Don't be.

  By the above, the invention described in Patent Document 1 makes the stop symbol of the effect symbol in one winning combination out of a plurality of types of winning combinations the same as the stop symbol of the effect symbol in the small win, It is an improvement in the interest of the game by making it difficult to determine which hit it is, and preventing the player from predicting the progress of the game rich in change.

JP 2006-1116016 A

  However, although the invention described in the above-mentioned Patent Document 1 makes the special symbol display part very small as compared to the display area of the effect symbol, it is difficult to determine which one is the effect symbol. After the game stops, the player has enough room to check the special symbol display section, and at this point, there is a possibility that the player will be identified.

  The present invention has been made in view of such circumstances, making it more difficult to determine which hit it is, and maintaining a sense of expectation without predicting the progress of a variety of games to the player. It is an object of the present invention to provide a gaming machine that can be played.

According to the present invention, the above problem is solved as follows.
In the present invention, when a game ball enters a starting port provided on the game board surface, a lottery determination is performed as to whether or not to win with a predetermined probability. A main control unit that can win any of the winning combinations, and the plurality of types of winning combinations include at least a probability variation that becomes the high probability in the normal gaming state after the winning process when the winning opening is opened. A non-probability variation per non-probability variation is set, and the per-probability variation per non-stochastic variation pertains to a game machine in which the stop symbol of the effect design is set to be the same or similar to each other, and the effect design Can be displayed in a variable manner, and the result of the winning / external lottery is notified by a display device for notifying the result of the winning / external lottery by the stop symbol of the effect symbol and a special symbol having a form different from the effect symbol. Special design chart And the effect intervention operation part for intervening the operation by the player in the effect displayed on the display device, and the effect symbol is variably displayed in response to the game ball entering the start opening. Control is performed to stop display after a predetermined time has elapsed, and the display state changes based on the operation of the effect intervention operation unit when the result of the lottery / outside lottery is per probability fluctuation or non-probability fluctuation. Effect control means for executing control to display a game participation type effect image on the display device, and the special symbol is displayed on the special symbol display unit to notify the result of the lottery / outside lottery In the meantime, the effect control means executes control to display the game participation type effect image.

  According to the present invention, it is difficult to determine whether the change is per probability change or per non-stochastic change, and it is possible to maintain a sense of expectation without predicting the progress of a game rich in changes to the player.

It is a front view of a gaming machine to which an embodiment of the present invention is applied. It is a control block diagram concerning a gaming machine. It is a game control block diagram in a main control part. It is a schematic diagram which shows the example of a display of the game participation type effect image displayed on a display apparatus. It is a flowchart figure for demonstrating the flow of the main part of a game.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the gaming machine 1 is configured by a gaming board 3 being fitted in an outer frame 2 and a display device 4 made of a liquid crystal display, for example, being disposed at a substantially central portion of the gaming board 3. By operating the operation handle 5 provided in the lower right front of the gaming machine 1 in the clockwise direction, the gaming balls stored in the ball storage tray 6 provided in the front of the gaming machine 1 are launched by a launching device (not shown). ) To a substantially circular game area 31 provided in front of the game board 3, a predetermined game as described later can be performed.

  On the upper part (or front surface) of the ball storage tray 6, there is provided an effect intervention operation button (effect intervention operation unit) 7 that can be operated by the player. The effect intervention operation button 7 is provided at a predetermined timing by the player at a predetermined effect intervention effective period (for example, a period in which the game participation type effect image 300 is displayed on the display device 4 as shown in FIG. 4). By being operated, the display of the game participation type effect image 300 displayed on the display device 4 is changed so that the game mode is determined by the player.

  Below the display device 4 is provided a special symbol starting port (starting port) 8 through which a game ball driven into the game area 31 can enter (or win). On both sides of the special symbol starting port 8, a normal symbol operating gate 9 through which a game ball can pass is provided.

  The special symbol starting port 8 can be changed between a first state in which the winning opening is enlarged and a second state in which the winning opening is reduced by opening and closing the left and right movable pieces 8a, 8a. There are two types of time for the first state: a normal time mode (for example, 0.5 seconds) and an extended time mode (for example, 2 seconds) that is longer than this. The extended time mode is set during the high probability mode period described later.

  On the upper part of the display device 4, there is provided a holding lamp 42 for displaying the presence or absence of up to four holdings by lighting. Note that “hold” refers to a notification of the result of a lottery / external lottery executed later when a game ball enters the special symbol start port 8 while the effect symbol 15 is variably displayed on the display device 4. To wait.

  When the game ball passes through the normal symbol operating gate 9, a main control unit 100, which will be described later, draws a lottery based on a predetermined probability to determine whether or not a quasi-special prize state is to be generated. The provided normal symbol display device 10 is variably displayed, and then a predetermined symbol is fixedly displayed.

  The normal symbol display device 10 performs a display in which the normal symbol display areas 10a and 10b each configured by an LED are alternately lit, and the normal symbol display area 10a is lit as a predetermined display mode. A special prize state is generated, and the left and right movable pieces 8a, 8a of the special symbol starting port 8 are opened for a predetermined time so that the game ball can easily win the special symbol starting port 8. FIG. 1 shows a state in which the left and right movable pieces 8a and 8a are opened.

  Below the special symbol starting port 8, a variable winning device 11 is arranged that can win a game ball driven into the game area 31. The variable winning device 11 is provided with a large winning opening 11a in which a wide door is opened to the front side during a hitting process, which will be described later, and a game ball can be won.

  A state where the door of the big winning opening 11a is opened and the game ball is physically easy to win is referred to as an advantageous state for the player. In addition, a state in which the door of the big winning opening 11a is closed and the game ball is difficult to physically win or cannot be won is referred to as a disadvantageous state for the player.

  In addition, the game area 31 is provided with a windmill 12 with a ramp for changing the rolling direction of the game ball together with the game nail, an out port 13 for sending the game ball to the back surface of the game board 3 and the like. A plurality of lamps 14 are provided around the game area 31. Note that game nails are omitted for simplification of the drawing.

  The display device 4 is shown in the effect symbols 15 (in the present embodiment, there are 10 types of numbers from 0 to 9 and one type of chance symbol) divided into three columns, left, middle, and right, and FIG. The game participation type effect image 300 can be displayed, and when the game balls that have been driven into the game area 31 enter the special symbol start opening 8, the left, middle and right three columns of the effect symbols 15 are displayed in a variable manner. (Scroll fluctuation in the vertical direction), and the effect symbol 15 is stopped and displayed after a lapse of a predetermined time, thereby notifying the player of the result of the lottery / outside lottery executed by the main control unit 100 described later. When the stop symbols of the three lines of effect symbols 15 are arranged in three lines of chance symbols, after the effect symbols 15 are stopped and displayed, the game participation type effect image 300 is displayed instead of the effect symbols 15.

  On the right side of the game area 31, a special symbol display portion 41 for two frames formed of LEDs is provided. The special symbol display unit 41 is for notifying the actual result of the lottery / outside lottery and the probability variation lottery executed by the main control unit 100 by the combination of the special symbols of the two frames.

  Since the special symbol of the special symbol display unit 41 needs to maintain a simple expression that only stops after scrolling when the game ball enters the special symbol start port 8, the directing symbol 15 is By interweaving various production patterns, it has the role of enhancing the production effect.

In the present embodiment, the big wins 1 to 3 and one kind of small win are set as the winning combination of the winning / outside lottery.
The jackpot 1 is that the stop symbol of the production symbol 15 is aligned with odd numbers of 1, 3, 5, 7, 9 and the special symbol of the special symbol display unit 41 has a predetermined color (for example, red). By aligning, the player is informed that the big hit 1 has been won. In the case of a big win, the game specification is such that the big prize opening 11a is changed to an open state for a predetermined time. During the winning process in this game specification, the player can obtain a lot of prize balls in a short period of time. Can do. Also, in the normal gaming state after the winning process, the probability of winning a big hit by the winning / outside lottery is higher than the normal probability mode (1/350 of the winning probability), and the probability is higher in the high probability mode (1/50 of the winning probability). fluctuate.

  In the big hit 2, the stop symbol of the production symbol 15 is an even number of 0, 2, 4, 6, and 8 aligned with a flat eye, and the special symbol of the special symbol display unit 41 has a predetermined color (for example, blue) By aligning, the player is informed that the big hit 2 has been won. In the case of a big win 2, the game specification is such that the special winning opening 11a is changed to an open state for a predetermined time. During the winning process in this game specification, the player can obtain a lot of winning balls in a short period of time. However, in the normal gaming state after the hit process, the normal probability mode is set and the probability does not change.

  In the big win 3 (per probability variation) and the small win, the display symbols (for example, 1, 2, 3) where the stop symbols of the effect symbols 15 are arranged in three rows of chance symbols or the numbers of the effect symbols 15 are continuous. Or 4, 5, 6, etc.) and the special symbol on the special symbol display unit 41 has a predetermined color (for example, red for the big hit 3 and yellow for the big hit). Notify one of the winners.

  In the case of the big hit 3, the game specification is such that the big winning opening 11a is opened only twice in a short time, and during the winning process in this game specification, the player gets a lot of winning balls in a short period of time. Although it cannot be expected, in the normal gaming state after the hit processing, the probability is changed to the high probability mode, and it is promised that the big hit will be made early. That is, the jackpot 3 becomes the game specification won in the probability variation lottery.

  In the case of small wins, the game specification is such that the big winning opening 11a is opened only twice in a short time, and during the winning process in this game specification, the player can obtain a lot of game balls in a short period of time. Not only can it not be expected, but even in the normal gaming state after the hit process, it becomes the normal probability mode and the probability does not change to the high probability mode. In other words, the small win is a game specification that does not win the probability variation lottery.

  As described above, in the big hit 3 and the small hit, the stop symbol of the effect symbol 15 and the number of times the big winning opening 11a is opened are the same, so the player simply looks at the stop symbol of the effect symbol 15, I know that I won the big win or the small win, but I can't tell if I won the random lottery. Therefore, in order to determine whether the big win or the small win has been won, the player needs to confirm the notification form of the special symbol on the special symbol display 41.

  When the big win 3 or the small win is won, the effect symbol 15 is stopped and displayed immediately after the effect symbol 15 is displayed and the lottery result is being notified to the special symbol display unit 41. The game participation type effect image 300 is displayed on the display device 4. In other words, the notification by the special symbol on the special symbol display 41 is executed within the effect intervention effective period in which the game participation type image 300 is displayed on the display device 4.

  Thereby, when the lottery result is notified to the special symbol display unit 41, the player is participating in the effect game of the game participation type effect image 300 displayed on the display device 4, The player's interest is toward the game participation type effect image 300, and it is difficult to determine the notification result displayed on the special display unit 41. Further, a message image 304 that prompts the player to operate the effect intervention operation button 7 is displayed on the game participation type effect image 300, thereby further increasing the player's interest in the game participation type effect image 300. The notification result of the special symbol display unit 41 is further difficult to discriminate.

  It should be noted that the effect symbol variation pattern including the variation display and stop display of the effect symbol 15 displayed on the display device 4, whether to set the high probability mode, and the notification form of the special symbol display unit 41 are the main control unit 100. Based on the lottery result, it is determined in advance, and the main control unit 100 controls the winning process in the case of a big hit.

FIG. 4 shows an example of the game participation type effect image 300 displayed on the display device 4 immediately after the effect symbol 15 is stopped and displayed.
In the game participation type effect image 300, as shown in FIG. 4A, the A mode area portion 301, the B mode area portion 302, and the C mode area portion 303 are repeatedly turned on and off in order along the arrow direction. At the same time, a message image 304 that prompts the user to press the production intervention operation button 7 is displayed.

  When the game intervention operation button 7 is operated at a predetermined timing by the player within the production intervention effective period (a period during which the game participation type production image 300 is displayed on the display device 4), it is shown in FIG. As described above, the light stops in any mode area (A mode 301 in FIG. 4B), and any mode is selected. For example, when the A mode 301 is selected, the game participation type effect image 300 disappears, the A mode effect image is displayed on the display device 4, and the probability change to the high probability mode during the normal game state after the end of the hit. That is, the big hit is 3. When the mode B is selected, the game participation type effect image 300 disappears, and the B mode effect image of the effect image different from the A mode effect image is displayed on the display device 4, and in the normal game state after the end of the hit Normal probability mode, that is, small hit. When mode C is selected, the game participation type effect image 300 disappears, and a C mode effect image of an effect image different from the A and B mode effect images is displayed on the display device 4. During the normal gaming state, the normal probability mode, that is, a small hit.

Note that the game participation type effect image 300 is not specified in the present embodiment. For example, the display of the game participation type effect image different from the present embodiment is changed by repeatedly pressing the effect intervention operation button 7. It is good also as the repeated striking effect etc. which were made.
Whether or not the game participation type effect image 300 is displayed after the effect display by the effect symbol 15 is ended may be determined based on the lottery by the lottery means by the main control unit 100 or the effect control unit 200. In addition, even if the result of the lottery / outside lottery by the main control unit 100 is a failure, the game participation type effect image 300 may be displayed by lottery based on a predetermined probability.

  Main devices among the devices disposed on the game board 3 are controlled by a microcomputer, which will be described with reference to a control block diagram shown in FIG. Note that control systems, power supply circuits, and the like that control the launching device and the prize ball discharging device, which are not shown, are not directly related to the present invention and are omitted here.

  The main control unit 100 is attached to the back side of the game board 3, and is configured as an integrated one-chip CPU together with a ROM that stores a control program and various data, and a RAM that functions as a work area of the CPU. The operation of each part is controlled by a program.

  The input port of the main control unit 100 is provided in the special symbol start port 8 and is provided in the special symbol start sensor 81 for detecting the passage of the game ball and the normal symbol operation gate 9 to detect the passage of the game ball. A normal symbol start sensor 91, a large winning opening sensor 11b that is provided in the large winning opening 11a in the variable winning apparatus 11 and detects a game ball that has won a prize in the large winning opening 11a, is also provided in the large winning opening 11a. A V zone sensor 11c for detecting a game ball that has passed through the V zone for continuing the opening / closing operation of the mouth 11a is connected.

  In the output port of the main control unit 100, the large winning opening solenoid 150 for opening the wide door of the large winning opening 11a in the variable winning apparatus 11 and the left and right movable pieces 8a, 8a of the special symbol starting opening 8 are opened. For this purpose, an ordinary electric accessory actuating solenoid 160, a special symbol display unit 41, and an effect control unit 200 for controlling the effects during the game are connected.

  A normal symbol display device 10, a windmill 12 with a lamp, a lamp 14, a speaker 16, and the display device 4 are connected to an output port of the effect control unit 200 via a symbol / audio control unit 210. The effect intervention operation button 7 is connected to the input port of the effect control unit 200.

  FIG. 3 is a functional block diagram mainly showing lottery control for determining the game specifications in the main control unit 100. A signal from the special symbol start sensor 81 is input to the lottery unit 101 of the main control unit 100. In the lottery unit 101, a winning / exit lottery for determining hit / miss and a probability variation lottery for determining whether or not to make a high probability in the normal gaming state after the winning process is executed.

  The lottery unit 101 issues a random number acquisition instruction to the random number acquisition unit 103, whereby the random number acquisition unit 103 acquires a random number from the hit / miss random number counter 104 and sends it back to the lottery unit 101. Thereby, the lottery unit 101 executes a winning / exit lottery to determine whether to win or miss.

  Subsequently, the lottery unit 101 instructs the random number acquisition unit 103 to acquire a random number again, and acquires a random number from the probability variable random number counter 105. The random number acquired by the random number acquisition unit 103 is returned to the lottery unit 101 again. Thereby, the lottery unit 101 executes a probability variation lottery as to whether or not to enter the high probability mode during the normal gaming state after the winning process.

  Note that the lottery unit 101 may acquire a random number from the winning / losing random number counter 104 and simultaneously execute the winning / extracting lottery and the probability variation lottery based on the acquired random number. In this case, the hit / miss random number counter 104 and the probability variation random number counter 105 are combined into one random number counter.

  In the lottery unit 101, the result of the lottery / outside lottery (the jackpot 1-3, the small hit / out), and the probability variation lottery result (high probability mode / normal probability mode) in the case of the jackpot are sent to the lottery result determination unit 107. Send.

  The lottery result determination unit 107 transmits / receives necessary data to / from the game progress control unit 102 based on the results of the current / outside lottery and the probability variation lottery, and the lottery result is displayed as a variation display pattern of the production symbol 15 It transmits to the effect design fluctuation pattern determination part 108 for determining.

  The effect symbol variation pattern determination unit 108 instructs the random number acquisition unit 103 to acquire a random number, and acquires a random number from the effect symbol variation pattern random number counter 109. The acquired random number is returned to the effect symbol variation pattern determination unit 108.

  In the effect symbol variation pattern, variation patterns such as a normal pattern, a normal reach pattern, a super reach pattern, a premium reach pattern, and the like having different expected values are prepared for each of hit / miss. In the variation pattern, the normal pattern has the lowest expected value, and the premium reach pattern has the highest expected value.

  In the case where the lottery unit 101 determines that the jackpot is 3, the jackpot or is off, whether or not the game participation type effect image 300 is displayed by the effect symbol variation pattern determination unit 108 or the effect control unit 200. A lottery may be performed. In this way, in the case of per probability change or small hit, in addition to the fact that the game participation type effect image is not always displayed, there is a possibility that the game participation type effect image is also displayed in the case of detachment. It is possible to make it more difficult to determine whether a winning or a small win is won. When displaying the game participation type effect image 300, any game participation type effect image may be selected from a plurality of types of player participation type effect patterns set in advance.

  The symbol variation pattern data determined by the effect symbol variation pattern determination unit 108 is transmitted to the command generation unit 111 and is transmitted to the effect control unit 200 via the command output unit 112 at a predetermined timing. Thereby, in the effect control part 200, the effect display by the effect symbol 15 is performed in the display apparatus 4 based on an effect symbol fluctuation pattern.

  The effect control unit 200 stores a program for effect control and various control commands for transmission to the symbol / voice control unit 210. The effect control unit 200 determines the effect pattern according to the effect symbol variation pattern determined based on the result of the lottery / outside lottery by the main control unit 100 by executing the effect process according to the program stored in the ROM. To do. As the control command for the effect control unit 200 to transmit to the symbol / sound control unit 210, the effect symbol variation pattern command acquired from the main control unit 200 and the result of the lottery by the main control unit 100, the big hit 3 or the small hit In this case, an effect image command for displaying the game participation type effect image 300 on the display device 4 for a predetermined time (effect intervention effective period), and the display device 4 when the effect intervention operation button 7 is operated by the player. There is a player intervention command for changing the display form of the game participation type effect image 300 displayed in FIG.

  When the game participation type effect image 300 is displayed on the display device 4, whether the big hit 3 or the small win is determined in advance according to the lottery result of the main control unit 100. That is, when the lottery result of the main control unit 100 is the big hit 3, the display effect is performed such that the mode A that becomes the high probability mode is selected, and in the case of the small hit, the mode B that becomes the normal probability mode. Alternatively, a display effect is performed so that mode C is selected. If the game intervention operation button 7 is not operated within the effective intervention effective period, the mode B or mode C is selected and the fact that it is once a small hit is displayed. Produce the display so that the probability changes to the high probability mode.

  Next, a main effect control routine in the main control unit 100 in the case of winning the big hit 3 and the small win will be described based on FIG.

  In response to the game ball entering the special symbol starting port 8, the main control unit 100 executes the winning / external lottery and the probability variation lottery process in step S1. As a result of the lottery, when the big hit is 3 or the small win, the effect symbol 15 is variably displayed based on the effect variation pattern determined by the winning / outside lottery in step S2, and the effect symbol 15 is stopped and displayed with the chance symbol.

  In step 3, the game participation type effect image 300 is displayed on the display device 4 in place of the effect symbol 15. In step S4, while displaying the game participation type effect image 300 on the display device 4, the special symbol display unit 41 is notified that the big win or the small win is made, and the big winning opening 11a is opened twice. Make it work.

  In step S5, when the game intervention operation button 7 is operated by the player within the production intervention effective period in which the game participation type production image 300 is displayed on the display device 4, the lottery result of the main control unit 100 in step S6. If the big hit is 3, the process proceeds to step 7, the A mode 301 is selected in the game participation type effect image 300, the A mode effect is executed, and the high probability mode in the normal game state after the hit process. The probability varies. Further, when the lottery result of the main control unit 100 is a small hit, the process proceeds to step 8 where the B mode 302 or the C mode 303 is selected in the game participation type effect image 300 and the B or C mode effect is executed. In addition, the normal probability mode is set in the normal gaming state after the hit processing.

  As described above, in the present embodiment, the winning symbols of the effect symbol 15 are the same for a plurality of types of winning combinations, but the jackpot 3 and the high probability mode which become the high probability mode in the normal gaming state after the winning process. After the effect display by the effect symbol 15 is finished, the display device displays the timing at which the special symbol display unit 41 notifies the actual lottery result executed by the main control unit 100. Since the game effect type effect image 300 is displayed in the middle of FIG. 4, it is difficult to determine whether the big hit 3 or the small win is won, and the progress of the game rich in change can be made. The expectation can be maintained without being predicted by the player.
