Abstract

<P>PROBLEM TO BE SOLVED: To increase the expectations of an advantageous mode advantageous for a player. <P>SOLUTION: When winning a probability variable winning in winning drawing, shifting to a probability variation mode is performed following a winning mode. At the time, shortening number-of-times drawing is performed and the number of times of ready-to-win states before the end of a shortening period is determined. During the shortening period, when special symbols are in the ready-to-win state when a game ball passes through a through chucker, the flickering time of a lamp indicating the result of opening drawing is shortened to 0.5 second. In the period other than the shortening period in a normal mode and the probability variation mode, the flickering time of the lamp indicating the result of the opening drawing is 8 seconds. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a gaming machine used in a game hall such as a pachinko parlor.

  In recent pachinko machines, a pair of movable pieces are provided at the start winning opening, and if the winning ball is won when a game ball passes through a through hole called a through chucker, the movable piece is opened and started. This makes it easier for game balls to win prizes. The result of the open lottery is displayed on, for example, a 7-segment display with 1-digit display. When “7” stops after the display of normal symbols is displayed on this display, the open lottery will be selected. Is lost. When a pachinko ball enters the starting prize opening in the game board, a lottery using a random number is performed, and special symbols such as numbers and marks are variably displayed on an image display device such as a liquid crystal display. When winning is determined by winning lottery, for example, the special symbols are stopped so that the same kind of symbols are aligned via the reach state as shown in Patent Documents 1 and 2, and winning is won Is displayed.

  When the same special symbol is displayed after winning the symbol change display, the winning mode is displayed after a certain period of time. In the winning mode, an open / close board (attacker) built in the game board surface is opened, and a large winning opening that is normally closed is exposed. When the big prize opening is exposed, most of the pachinko balls flowing down the game board face are in a state where it is easy to win. When the attacker opens and a certain time elapses, or when a certain number of pachinko balls enter the winning prize opening, the attacker temporarily closes (end of the first round). In the second and subsequent rounds, the attacker is similarly controlled to open and close, and for example, it is normal to be able to repeat up to the 15th round.

As described above, there are pachinko machines that shift to the hit mode, such as a probability variation mode in which the winning probability of winning is higher than that in the normal mode and a mode in which the variation time of special symbols is shorter than the normal mode. In general, the probability variation mode continues until winning, and the time reduction mode ends when the number of variations of the special symbol reaches a specified number. In the probability variation mode and the short-time mode, the variation time of the normal symbol is shorter than that in the normal mode. Furthermore, in the normal mode, the movable piece is released once for each winning lottery, whereas in the open lottery 1 The movable piece is released three times for each winning. Thereby, in the probability variation mode and the short time mode, the winning rate of the game balls at the start winning opening becomes higher than that in the normal mode, and it is possible to play the game while suppressing the decrease of the hand-held game balls.
Japanese Patent Application Laid-Open No. 06-233861 JP 2003-144669 A

  However, the probability of winning in the probability variation mode is high, but it is not always the case that the player wins again in a short period of time. In some cases, the games in the game become redundant with the normal mode. Also, in the short-time mode, the winning probability is not changed, and it is only possible to play while suppressing the consumption of game balls, so the short-time mode may end without winning. There were many, and the player's expectation to the short time mode was weak.

  The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a gaming machine that can enhance the expectation of an advantageous mode advantageous to a player.

  In order to achieve the above object, the gaming machine according to claim 1 is provided with a winning opening in which the movable piece opens and closes and the winning rate of the gaming ball changes, and the gaming ball is detected by a passage opening different from the winning opening. An open lottery for determining whether or not to release the movable piece is performed, and the result of the open lottery is displayed by performing a change display and a stop display of normal symbols, and the open lottery is won. Then, after the stop display, the movable piece is released, and the game is played in the advantageous mode that is more advantageous to the player than in the normal mode or the normal mode, and in the normal mode or the advantageous mode, a specified number of hit rounds are executed. In a gaming machine in which a winning lottery for determining whether or not to shift to the winning mode is performed and the result of the winning lottery is displayed after a special symbol change display, the winning lottery is performed in the advantageous mode. Reach display determination means for determining whether or not to display the reach state in the process of displaying the special symbol every time it is displayed, and while the reach state is displayed in the advantageous mode, the normal symbol starts to change more than the normal mode. And a fluctuation control means for shortening the fluctuation time from stop to display.

  In addition, it is preferable to provide a shortening period lottery means for determining a shortening period in which the variation time of the normal symbol is shortened by a shortening period lottery.

  The reach display determining means determines whether or not to display a reach state by reach display lottery, and is used in the reach display lottery, and a plurality of reach display tables having different probabilities that the reach state is displayed; It is preferable to provide a table selection means for selecting a reach display table having a relatively high reach display probability and performing a reach display lottery when a predetermined selection condition is satisfied in the advantageous mode.

  Note that, when the advantage mode is entered, the reach display table having a relatively high probability that the reach state is displayed is selected, and the period during which the reach display lottery is performed is determined from the high probability period lottery. It is preferable that a certain period lottery unit is provided, and the table selection unit selects the reach display table having a relatively high probability that a reach state is displayed until the period elapses after shifting to the advantageous mode.

  In addition, there is provided a fluctuation number counting means for counting the number of fluctuations of the special symbol in the advantageous mode, and the table selecting means has a predetermined number of preset times after the transition to the advantageous mode. It is preferable to select the reach display table having a relatively high probability that the reach state is displayed.

  The “advantageous mode” described in claim 1 is a game mode that is more advantageous than the normal mode when the player obtains a game profit and is provided separately from the hit mode. Probability variation mode in which the probability of winning a win is higher than in the mode, the variation time of the symbol is shortened compared to the normal mode, and movable to open and close the start winning opening and change the winning rate of the game ball to the starting winning opening A time reduction mode in which the opening time of the piece is longer than in the normal mode (the time until the result of the opening lottery for determining whether or not to open the movable piece is shortened) is also included.

  According to the present invention, while the reach state is displayed in the advantageous mode, the fluctuation time of the normal symbol is shortened compared to the normal mode. Therefore, when the reach state is displayed in the advantageous mode, it is movable more than the other times. It becomes possible to increase the number of times the pieces are released, and the number of game balls can be increased during the advantageous mode. Thereby, the expectation to an advantageous mode can be raised.

  In addition, since the shortening period in which the fluctuation time of the normal symbol is shortened is determined by the shortened period lottery, it becomes possible to increase the player's expectation for the result of the shortened period lottery and increase the expectation for the advantageous mode be able to.

  In addition, since the winning probability of the reach display lottery increases when a predetermined selection condition is satisfied in the advantageous mode, it becomes possible to increase the player's expectation for the reach display lottery, and to enter the advantageous mode. Expectation can be raised.

  Further, since the period during which the reach display lottery is performed is determined from the high-probability period lottery, it is possible to increase the player's expectation for the high-probability period lottery and the expectation for the advantageous mode.

  In addition, since the winning probability of the reach display lottery increases when the number of times of change after shifting to the advantageous mode reaches a predetermined number of times set in advance, the game ball is increased when the game period becomes long This makes it possible to eliminate tiredness when the game period is long, and to reduce the consumption of game balls.

  In FIG. 1, a pachinko machine 10 according to the first embodiment includes a game board 10a. A game area 11 is formed on the front surface of the game board 10a, and a game ball launched in response to a player's launch operation flows down the game area 11. The game area 11 is provided with a start winning opening (hereinafter referred to as “start opening”) 12, a normal winning opening (hereinafter referred to as “normal opening”) 13, and a through chucker 14. When a game ball wins the start port 12 or the normal port 13, a predetermined number of game balls are paid out as a prize ball. The game balls that have been paid out can be used for games. The start port 12 is provided with a pair of movable pieces 12a. The start opening 12 changes the winning rate of the game ball by opening and closing the movable piece 12a. When the movable piece 12a is opened, a game ball can easily enter the start port 12. Whether or not to open the movable piece 12a is determined by an open lottery executed when a game ball passes through the through chucker 14. The result of the open lottery is displayed with a lamp 15a indicating a circle and a lamp 15b indicating a cross. When the game ball passes through the through chucker 14, the lamp 15a and the lamp 15b are alternately flashed and displayed, and one of the lamps 15a and 15b remains lit. When the lamp 15a is lit and displayed, it is “winning”, and when the lamp 15b is lit and displayed, it is “lost”. In this way, the ◯ mark and the X mark function as “ordinary symbols” in the claims, and the alternating blinking display of the lamps 15a and 15b functions as “ordinary symbol fluctuation display” in the claims. Although not shown in detail, the game area 11 is provided with game nails and windmills that change the movement of the flowing game balls.

  A center accessory 16 is provided at the center of the game area 11. A liquid crystal display 17 for displaying the result of the winning lottery is provided in the center accessory 16.

  A special symbol 19 arranged in three columns is displayed on the liquid crystal display 17, and the special symbol 19 in each column is composed of, for example, ten numbers of 0 to 9. When a game ball wins at the start port 12, a winning lottery for determining a winning or losing is performed, and then the special symbol 19 starts to change and the special symbol 19 scrolls from top to bottom. The special symbols 19 are sequentially stopped one by one (in the order of left column → right column → center). When all the special symbols 19 are stopped, the same special symbol 19 is found, and other combinations are lost. It becomes. For this reason, when the same special symbol 19 is stopped in the left and right columns, the reach state is reached, and after the reach state is displayed, the same special symbol 19 as the left and right special symbols 19 is stopped in the center.

  If the winning is won, the normal mode is changed to the winning mode, the attacker 20 is released, and the round game is performed. When the attacker 20 is opened, the big prize opening is exposed from the board surface, and most of the game balls are guided to the big prize opening on the inner surface of the attacker 20. Thereby, a large number of prize balls can be obtained in the winning mode. The attacker 20 is closed when a predetermined number (for example, 10) of game balls wins in the big winning opening or when the opening time of the big winning opening becomes 30 seconds, for example, and the first round is ended. In the hit mode, the opening and closing of the attacker 20 is repeated and the process ends in the fifteenth round.

  The pachinko machine 10 can be played in the probability variation mode in addition to the normal mode and the winning mode. When transitioning to the probability variation mode, the probability of winning a win is higher than in the normal mode. Whether or not to shift to the probability variation mode is assigned with a probability of 1/2 when winning. When the transition to the probability variation mode is determined, the mode transitions to the probability variation mode following the hit mode.

  Further, in the pachinko machine 10, the blinking time of the lamps 15a and 15b when the game ball passes through the through chucker 14, that is, the variation time of the normal symbol changes depending on the game state. In the normal mode, the blinking time of the lamps 15a and 15b is 8 seconds. In the probability variation mode, the reach number determined in the shortened number lottery described later is exhausted and the reach state is being displayed. The flashing time of the lamps 15a and 15b is 0.5 seconds, and otherwise, the flashing time of the lamps 15a and 15b is 8 seconds. In any case, the opening time of the movable piece 12a is 0.2 seconds per opening.

  A holding ball display unit 21 is provided above the liquid crystal display 17. The holding ball display unit 21 includes four lamps. If the pachinko ball wins the starting opening 12 during the variable display of the special symbol 19 or the winning mode, the right of the winning lottery is carried over as a holding ball up to four. In the holding ball display unit 21, when one holding ball is stored, one lamp is turned on. The retained ball carried over is digested after the change display of the symbol or after the hit mode ends. When one reserved ball is digested, one lamp of the reserved ball display unit 21 is turned off, and the special symbol 19 is displayed once.

  In FIG. 2, the pachinko machine 10 includes a control unit (variation control means) 30. The control unit 30 controls the overall operation of the pachinko machine 10 such as opening / closing control of the attacker 20 and display control on the liquid crystal display 17 in accordance with a game control program stored in the working memory 31.

  The start winning sensor 32 detects a game ball that has entered the start port 12. The normal winning sensor 33 detects a game ball that has entered the normal mouth 13. The through sensor 34 detects that a game ball has passed through the through chucker 14. The prize ball payout device 35 pays out a specified number of game balls as prize balls in response to a payout command input when a game ball wins at the start port 12 or the normal port 13. The game ball launching device 36 launches game balls one by one into the game area 11 in response to the turning operation of the launch handle of the player. The launch strength of the game ball is adjusted according to the amount of rotation of the launch handle. The attacker drive device 37 opens and closes the attacker 20 in the hit mode.

  The winning lottery unit 38 receives a command from the control unit 30 when a game ball wins at the start port 12 and performs a winning lottery using a random number to determine a winning or a lose. As the winning, a normal winning that is shifted only to the winning mode and a probability changing winning that is shifted to the probability variation mode after the winning mode are set. In the winning determination table used in the winning lottery, all random numbers extracted in the lottery are assigned with one of lost, normal winning, and probability variation. Then, the random value extracted at the time of the lottery is collated with the hit determination table, and it is determined which of the lost random value, the normal hit, and the probability variation is assigned to the collated random value. The winning judgment table is composed of a normal table used in the normal mode and a probability variation table used in the probability variation mode. In the probability variation table, the winning assignment is assigned so that the winning probability of winning is higher than that of the normal table. The number of random values is determined. Note that in the winning lottery, only the loss or the winning may be determined, and when the winning is won, the lottery for determining the normal winning or the probable change may be executed separately from the winning lottery.

  The open lottery unit 39 performs an open lottery using a random number in response to a command input from the control unit 30 when a game ball passes through the through chucker 14, and determines whether or not to release the movable piece 12a. . When the open lottery is performed, the control unit 30 alternately blinks and displays the lamps 15a and 15b, and lights and displays the lamps 15a and 15b corresponding to the lottery result. When the open lottery is won, the control unit 30 drives a solenoid (not shown) that drives the movable piece 12a to open and close the movable piece 12a.

  The variation pattern lottery section (reach display determining means) 40 is operated after the winning lottery is completed. The variation pattern lottery unit 40 selects the variation pattern and the stop symbol of the special symbol 19 by variation pattern lottery (reach display lottery) using random numbers. The variation pattern lottery unit 40 includes a lose table 40a and a winning table 40b. If the winning lottery result is a lost, the lost table 40a, and the winning lottery result is a win. The variation pattern lottery is performed using the winning table 40b. Although the variation pattern of the winning table 40b is always displayed through the reach state, the variation pattern of the loss table 40a is mostly displayed without the reach state, but the reach state is displayed. Also included are those that display lost via. For this reason, it can be paraphrased that it is determined whether or not to display the reach state when the variation pattern lottery is performed using the lose table. In this way, by performing the fluctuation pattern lottery using the table corresponding to the result of the winning lottery, the combination of the stop symbols corresponding to the winning lottery result is determined, and also varies with the probability according to the winning lottery result. A pattern is selected. Then, by selecting a variation pattern depending on whether or not it is a hit, for example, a variation pattern that is easy to select when winning or a variation pattern that is easy to select when losing can be set, and the special symbol 19 is variably displayed. You can enhance the fun of the game when you are.

  The shortening number lottery section (shortening period lottery means) 41 is activated when the probability change mode is entered. In the shortened number lottery unit 41, a shortened period for shortening the blinking time of the lamps 15a and 15b from 8 seconds to 0.5 seconds in the reach state is determined by a shortened number lottery (shortened period lottery) using random numbers. In the shortened number lottery, the number of reach states (hereinafter “reach number”) until the shortened period ends is determined, and the length of the shortened period is defined by the number of reach. The reach number determined in the shortened number lottery is set in the reach number counting unit 42. The reach number set in the reach count unit 42 is subtracted every time the reach state is displayed in the probability variation mode. Thereby, the number of reach times until the shortening period ends is counted. Until the shortening period ends, the control unit 30 performs blinking control of the lamps 15a and 15b so that the blinking time of the lamps 15a and 15b in the reach state is 0.5 seconds. Note that the shortened number of times lottery may be executed at an appropriate timing as long as it is executed in response to the winning per probability change.

  Next, the flow of the opening process of the movable piece 12a will be described with reference to FIGS. In the pachinko machine 10, the game is started in the normal mode. Pachinko balls launched into the game area 11 of the game board 10a are won at the start port 12 or the normal port 13, passed through the through chucker 14, or collected as an out ball. When the game ball passes through the through chucker 14 and is detected by the through sensor 34, the open lottery unit 39 performs an open lottery. When the open lottery is completed, the lamps 15a and 15b are alternately blinked for 8 seconds. When the blinking display of the lamps 15a and 15b ends, one of the lamps 15a and 15b is turned on and the result of the open lottery is displayed. When the open lottery is won, the movable piece 12a is opened for 0.2 seconds.

  Further, when a game ball wins at the start port 12, the winning ball is paid out and the winning lottery unit 38 performs a winning lottery. When the winning lottery is completed, the variation pattern lottery is performed using the lost table 40a or the winning table 40b according to the result. When the variation pattern lottery is completed, the variation display of the special symbol 19 is started. When the special symbols 19 are stopped and the same types of special symbols 19 are arranged, the mode is changed to the hit mode.

  In the hit mode, 15 round games are played. In the case of winning the normal winning in the winning lottery, the mode is shifted to the normal mode following the winning mode, and the above processing is repeated.

  If the winning lottery is won by winning, the mode is shifted to the probability variation mode after the winning mode. At this time, the shortened number lottery unit 41 performs the shortened number lottery and determines the reach number until the shortening period ends. The reach number determined in the shortened number lottery is set in the reach number counting unit 42. Each time the reach state is displayed in the probability variation mode, the reach count set in the reach count section 42 is subtracted.

  The control unit 30 identifies whether or not it is during the shortening period by referring to the count value of the reach count unit 42 each time the reach state is displayed. During the shortening period, the control unit 30 shortens the blinking time of the lamps 15a and 15b to 0.5 seconds when the special symbol 19 is in the reach state when the game ball passes through the through chucker 14. When the open lottery is won, the movable piece 12a is opened for 0.2 seconds after the blinking display of the lamps 15a and 15b is completed.

  The shortening period is continued until the reach count set in the reach count counter 42 becomes “0”, and the above processing is repeated. Further, after the reach count set in the reach count counter 42 becomes “0”, the shortening period ends, and when the game ball passes through the through chucker 14, the lamp 15a, The blinking time of 15b is 8 seconds.

  As described above, the blinking time of the lamps 15a and 15b is shortened during the reach state during the shortening period of the probability variation mode. Therefore, if the winning lottery is won continuously, the movable piece 12a repeatedly opens and closes intermittently. This makes it easier to win the game ball at the start opening 12. Thereby, the game ball can be increased during the probability variation mode.

  Next, a second embodiment will be described. In the second embodiment, a reach high probability period in which the probability that the reach state is displayed during the probability variation mode is relatively high is provided. In addition, about the same member and function part as 1st Embodiment, detailed description is abbreviate | omitted using the same code | symbol.

  As shown in FIG. 5, the pachinko machine according to the second embodiment includes a variation pattern lottery unit (reach display determination unit) 50 having a configuration different from that of the variation pattern lottery unit 40. The variation pattern lottery unit 50 is operated after the winning lottery is completed. In the variation pattern lottery unit 50, the variation pattern and the stop symbol of the special symbol 19 are selected by variation pattern lottery using random numbers. The variation pattern lottery unit 50 includes a lose table 51 and a winning table 52. When the winning lottery result is a lost, the lost table 51, when the winning lottery result is a win. The variation pattern lottery is performed using the winning table 52. Thereby, a combination of stop symbols corresponding to the winning lottery result is determined, and a variation pattern is selected with a probability corresponding to the winning lottery result.

  The lose table 51 includes a reach high probability table (reach display table) 51a and a reach low probability table (reach display table) 51b. In the reach high probability table 51a, the selection rate of the variation pattern is set so that the probability that the reach state is displayed is lower than that in the reach low probability table 51b. That is, the reach high probability table 51a has a higher selection rate of the variation pattern in which the loss is displayed via the reach state than the reach low probability table 51b. The reach high probability table 51a is used in a probability variation mode, which will be described later, during a reach high probability period, and the reach low probability table 51b is used in a normal mode and a probability variation mode, when the reach is not a reach high probability period (reach low probability period). . In the variation pattern of the winning table 52, the winning is always displayed via the reach state.

  The high probability period lottery unit (high accuracy period lottery means) 53 determines the length of the reach high probability period by the high probability period lottery. In the high probability period lottery, the number of reach times until the reach high probability period ends is determined, and the length of the reach high probability period is defined by the number of reach times. In the reach high probability period, when the result of the winning lottery in the probability variation mode is lost, the variation pattern lottery is performed using the reach high probability table 51a.

  Next, the flow of the opening process of the movable piece 12a in the pachinko machine of the second embodiment will be described. In addition, description is abbreviate | omitted about the part to which the same process as 1st Embodiment is performed, and the process after transfering to a probability variation mode is demonstrated.

  As shown in FIG. 6 and FIG. 7, when winning per probability change in the winning lottery and shifting to the probability variation mode, the high probability period lottery unit 53 performs the high probability period lottery until the reach high probability period ends. Reach times are determined. The reach count determined in the high probability period lottery is set in the reach count section 42. Each time the reach state is displayed in the probability variation mode, the reach count set in the reach count section 42 is subtracted. The control unit (table selection means) 30 identifies the reach high probability period or the reach low probability period by referring to the count value of the reach count unit 42 each time the reach state is displayed. When it is identified that the high probability period is in effect, a reach high probability signal is input to the fluctuation pattern lottery unit 50 each time the winning lottery is completed. In response to this, during the reach high probability period, when the winning lottery result is lost, the variation pattern lottery is performed using the reach high probability table 51a. Thereby, during the reach high probability period, the display probability of the reach state is higher than at other times.

  During the probability variation mode, when the special symbol 19 is in the reach state when the game ball passes through the through chucker 14, the blinking time of the lamps 15a and 15b is shortened to 0.5 seconds. When the open lottery is won, the movable piece 12a is opened for 0.2 seconds after the blinking display of the lamps 15a and 15b is completed.

  The reach high probability period is continued until the reach count set in the reach count counter 42 becomes “0”, and the above processing is repeated. Further, after the reach count set in the reach count counter 42 becomes “0”, the control unit 30 changes the reach low probability signal indicating that the reach low probability period is in effect every time the lottery is performed. Input to the lottery unit 50. In response to this, the variation pattern lottery unit 50 performs the variation pattern lottery using the reach low probability table 51b when the result of the winning lottery is lost.

  As described above, since the blinking time of the lamps 15a and 15b is shortened in the probability variation mode, if the winning lottery is continuously won during the reach state, the movable piece 12a repeatedly opens and closes intermittently, and the game ball Is easily awarded to the start port 12. In addition, since the display probability of the reach state is high during the reach high probability period, it is possible to increase the chances of winning the game ball at the start port 12 during the reach high probability period. Thereby, the game ball can be increased during the probability variation mode.

  Next, a third embodiment will be described. In the third embodiment, a reach high probability period during which the probability that the reach state is displayed during the probability variation mode is high is provided. In addition, about the same member and function part as 1st, 2nd embodiment, detailed description is abbreviate | omitted using the same code | symbol.

  As shown in FIG. 8, the pachinko machine according to the third embodiment includes a variation pattern lottery unit 50 having the same configuration as that of the second embodiment, but the opportunity for using the reach high probability table 51 a is second. Different from the pachinko machine of the embodiment. The pachinko machine according to the third embodiment includes a variation count counting unit (variation count counting means) 60. The number of changes “1000” of the special symbol 19 is set in the change count section 60 when the mode is shifted to the probability change mode. Then, every time the special symbol 19 is displayed in a variable manner, the value of the fluctuation count section 60 is subtracted. Then, the control unit 30 switches between the reach high probability table 51a and the reach low probability table 51b depending on whether or not the count value of the fluctuation number counting unit 60 is “0”.

  Next, the flow of the opening process of the movable piece 12a in the pachinko machine of the third embodiment will be described. In addition, description is abbreviate | omitted about the part to which the same process as 1st Embodiment is performed, and the process after transfering to a probability variation mode is demonstrated. Further, since the opening process of the movable piece 12a during one game is the same as that of the second embodiment, it will be described with reference to FIG. 7 as in the case of the second embodiment.

  As shown in FIG. 7 and FIG. 9, when winning per probability variation in the winning lottery and shifting to the probability variation mode, “1000” is set in the variation count section 60 and the variation display of the special symbol 19 is performed each time. The value of the variation count unit 60 is subtracted. The control unit (table selection means) 30 identifies either the reach high probability period or the reach low probability period by referring to the count value of the variation count unit 60 every time a winning lottery is performed. At this time, until the count value of the fluctuation number counting unit 60 becomes “0”, that is, until the number of fluctuations of the special symbol 19 after the transition to the probability fluctuation mode becomes 1000, the control unit 30 reduces the reach. A reach low probability signal indicating that it is in the probability period is input to the variation pattern lottery unit 50. In response to this, the variation pattern lottery unit 50 performs the variation pattern lottery using the reach low probability table 51b when the result of the winning lottery is lost. When the number of symbol variations exceeds 1000, the control unit 30 inputs a reach high probability signal indicating that the reach high probability period is in effect to the variation pattern lottery unit 50 every time a winning lottery is performed. In response to this, the variation pattern lottery unit 50 performs the variation pattern lottery using the reach high probability table 51a when the winning lottery result is lost. Thereby, when the number of symbol variations exceeds 1000 in the probability variation mode, the probability that the reach state is displayed increases.

  During the probability variation mode, if the special symbol 19 is in the reach state when the game ball passes through the through chucker 14, the blinking time of the lamps 15a and 15b is shortened to 0.5 seconds. When the open lottery is won, the movable piece 12a is opened for 0.2 seconds after the blinking display of the lamps 15a and 15b is completed.

  As described above, since the blinking time of the lamps 15a and 15b is shortened in the probability variation mode, if the winning lottery is continuously won during the reach state, the movable piece 12a repeatedly opens and closes intermittently, and the game ball Is easily awarded to the start port 12. In addition, if the number of symbol changes exceeds 1000, the reach probability is increased, so that the game redundancy in the probability variation mode can be eliminated for a long time, and the probability The ball can be prevented from decreasing in the fluctuation mode.

  In the first embodiment, the shortening period is determined based on the number of times of reach. However, an appropriate period such as the number of fluctuations and time of the special symbol 19 may be determined as the shortening period.

  In the second embodiment, the reach high probability period is determined based on the number of reach times. However, an appropriate period such as the number of fluctuations and time of the special symbol 19 may be determined as the reach high probability period.

  In the third embodiment, the reach high probability period is set when the number of fluctuations of the special symbol 19 reaches a predetermined number, but the reach high probability is reached when an appropriate period such as the number of fluctuations or time of the special symbol 19 has elapsed. It may be a period.

  In each of the above embodiments, the blinking time of the lamps 15a and 15b is shortened while the reach state is being displayed regardless of the type of the variation pattern. However, for example, the reach state is being displayed with the variation pattern having a relatively low selection probability. For example, the blinking time may be shortened while the reach state is displayed for a specific variation pattern.

  In each of the above embodiments, the result of the open lottery is displayed by the lamps 15a and 15b. However, the result of the open lottery may be displayed by an appropriate method such as providing a 7-segment display or using the liquid crystal display 17.

  In the description of the embodiments, each embodiment has been described by distinguishing between the first to third embodiments. However, these embodiments may be combined appropriately.
