Description

  The present invention relates to a pachinko machine that uses a game ball to play a game.

  In general, pachinko machines are provided with a special symbol display device that displays special symbols in the game area in the game board, an effect display device that displays a predetermined effect, a specific winning opening (starting port) that triggers an electronic lottery, etc. When the game ball launched toward the game area wins the specific winning opening, an electronic lottery related to the special symbol is performed, and the special symbol display device changes the special symbol and then stops. Is displayed to notify the result of the electronic lottery. If the result of the electronic lottery (per special symbol) is reached, the special symbol indicating that it is a special symbol display device is stopped and displayed, and the game is shifted to a jackpot gaming state that is advantageous to the player. In this jackpot game state, the game ball enters the big winning opening that is exposed by opening and closing the attacker device a predetermined number of times, so that the player can acquire many prize balls.

  In many cases, there are two types of electronic lottery related to this special symbol, that is, normal winning and probable change. If you win per probable change, when the jackpot gaming state ends, the special symbol A probability variation state in which the probability of winning in the lottery is high until it is won in the electronic lottery (so-called probability variation mode. A state in which a high probability determination table is used as the success / failure determination table used in the electronic lottery related to special symbols. ) In general.

  Further, an accessory called an electric tulip is provided at the specific winning opening, and when the electric tulip is opened, it becomes easier for a player to win a game ball to the specific winning opening. In order to open the electric tulip, it is necessary to win in the electronic lottery related to the normal symbol performed when the game ball passes through the through chucker (gate through which the game ball passes) provided in the game area. .

  In such a pachinko machine, when the big hit game is finished, the game state (so-called time reduction mode) in which the variation time of the special symbol is shortened by a predetermined number of games is shifted. In this short time mode, the probability of winning in the electronic lottery related to the normal symbol is increased (a high probability determination table is used as the success / failure determination table used in the electronic lottery related to the normal symbol). Since the tulip opens, it becomes easy for the game ball to win a specific winning opening, and the award ball is obtained by the win. Therefore, in this short time mode, the game ball is not reduced so much. For this reason, the player somehow plays the game while expecting to win in the electronic lottery related to the special symbol within the predetermined number of games until the short mode ends at this time.

  As described above, in the conventional pachinko machine, there are a normal mode that is a normal game state, a probability variation mode, a short time mode, and the like as described above, and when the jackpot game state ends, the game mode is determined from the normal mode. A variety of games are offered by shifting to the variable mode and the short-time mode.

  In addition, in order to shift to a wider variety of game modes, for example, as shown in Patent Document 1, there is a device that shifts to a probability variation mode for a predetermined number of games and then shifts to a time reduction mode. is there.

JP 2004-33317 A (paragraph 0033, FIG. 5, etc.)

  However, in such a pachinko machine, when the short-time mode ends, the probability of winning in the electronic lottery related to the normal symbol at that time also returns from the high probability to the normal probability, so the number of game balls will decrease in subsequent games As a result, the player's interest is reduced and the player is forced to play a boring game. As a result, players often stop playing games when the short-time mode ends, leading to a decline in the operation of pachinko machines.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is to maintain the fun of the game even if the advantageous mode (such as the time reduction mode) of the predetermined number of games is completed, and the game becomes boring. The purpose is to provide a pachinko machine that never happens. It is another object of the present invention to provide a pachinko machine that can prevent a decrease in operation.

  In order to achieve the above object, the present invention has a special design triggered by a game board having a game area in which game balls flow down, a start opening provided in the game area, and a game ball winning in the start opening. A special symbol lottery means for performing electronic lottery according to the above, a special symbol display device for displaying a lottery result by the special symbol lottery means by a display mode for stopping after changing the special symbol, and provided in the gaming area, An attacker device that operates during the jackpot game that is provided when a special symbol lottery means a lottery is won and allows a winning of a game ball, and is provided in the game area, and the game ball passes through the inside A possible through chucker, a normal symbol lottery means for performing an electronic lottery related to a normal symbol when a game ball passes through the through chucker, and an entrance of the start opening, An electric tulip that opens and closes when a normal symbol is won in a lottery by the normal symbol lottery means, and makes it easy to win a game ball at the start opening, and the special symbol lottery means generates a random number And a special symbol random number generating unit for acquiring one random number from random numbers generated by the special symbol random number generating unit when a game ball is won at the start opening. , A determination table used for determining whether or not the random number acquired by the special symbol random number acquisition unit is per the special symbol, the special symbol low probability determination table having a low probability of winning per the special symbol And a special symbol high probability determination table having a higher probability of winning per special symbol than the special symbol low probability determination table, the normal symbol lottery means, Random number generating means for normal symbols for generating numbers, and random numbers for normal symbols for acquiring one random number among the random numbers generated by the random number generating means for normal symbols when the game ball passes through the through chucker A determination table used for determining whether the random number acquired by the acquisition means and the normal symbol random number acquisition means is per the normal symbol, the normal symbol low with a low probability of winning per the normal symbol In a pachinko machine having a probability determination table and a normal symbol high probability determination table having a higher probability of winning per normal symbol than the normal symbol low probability determination table, the special symbol and the normal symbol per the special symbol. There are at least two types of odds per probability change, and the game mode includes the special symbol low probability determination table, And the first mode in which the normal symbol low probability determination table is used, the special symbol high probability determination table, the second mode in which the normal symbol high probability determination table is used, and the special symbol high probability determination table, And at least four game modes: a third mode in which the normal symbol low probability determination table is used, and a special mode low probability determination table and a fourth mode in which the normal symbol high probability determination table is used. If the winning game is won in the first mode, the game is shifted to the second mode when the jackpot game ends, and the game in the second mode is limited to the first number of games. And if the winning game is won within the first number of games in the second mode, the first game is completed when the jackpot game is over. On the other hand, if the player wins the probability change within the first number of games, the game in the second mode is performed again with the first number of games as the upper limit when the jackpot game ends. If the special symbol is not won within the first number of games, the game shifts to the third mode. If the normal game is won in the third mode, the jackpot game is entered. Upon completion of the game, the mode is shifted to the fourth mode, and the game in the fourth mode is performed with the second game count higher than the first game count as the upper limit.

  In the present invention, when winning per odd change is won in the first mode, the game shifts to the second mode when the jackpot game ends. The game in the second mode is performed up to the first number of games (for example, 10 times), and if it is not won per special symbol (per normal and probable) during this time, the game shifts to the third mode. . Then, when the normal win is won in the third mode, the game shifts to the fourth mode after the jackpot is over, and the game in the fourth mode is limited to the second number of games (for example, 100 times) higher than the first number of games. Will be done.

  Here, in order to shift to the third mode, in the second mode, the special symbol lottery means does not win the special symbol within the first number of games. In other words, only the first number of games is won. The condition is to continue to lose. Only when this condition is achieved, the mode can be shifted to the third mode. In addition, since the condition for shifting to the fourth mode is to win a normal win in the third mode, in order to shift to the fourth mode, first, within the first mode, the number of special symbols will be reduced within the first mode. The main premise is not to win.

  Since the fourth mode is a mode in which the special symbol low probability determination table and the normal symbol high probability determination table are used, the electric tulips frequently open and close. Therefore, in the fourth mode, it can be said that the game ball can be won at the starting port without almost reducing the game ball, which is one of advantageous states for the player. In addition, since the fourth mode is a game mode that is performed with the second game count higher than the first game count as the upper limit, it is still more advantageous for the player.

  In order to shift to the fourth mode advantageous to the player in this way, as described above, first, in the second mode, it is a condition that the special symbol lottery means does not win a special symbol in the electronic lottery means. In the second mode, the player plays the game while praying in the hope of not winning (losing) within the first number of games. This is the opposite of enjoying a game while wishing to win within a predetermined number of games.

  That is, according to the present invention, in order to shift to the third mode and the fourth mode, the condition that the special symbol is not won within the first number of games in the second mode is set. When the game is not won within the mode, the game is stopped when the predetermined number of games are finished. In the present invention, however, the game is played when the game is not won within the predetermined number of games. In order to shift to a mode advantageous to the player, a game after a predetermined number of games is more attractive to the player. Therefore, even if the second mode is finished, the fun is still maintained and the game is not bored. In addition, when the mode is shifted from the second mode to the third mode or the fourth mode, it is advantageous to the player. Therefore, the player continues the game even after the second mode is finished, and the pachinko machine is operated. It greatly contributes to preventing the decrease.

  In order to achieve the above object, in another invention, a game board having a game area where game balls flow down, a start opening provided in the game area, and a game ball winning in the start opening are triggered. A special symbol lottery means for performing electronic lottery related to the special symbol, a special symbol display device for displaying a lottery result by the special symbol lottery means in a display mode for stopping after changing the special symbol, and provided in the game area And an attacker device that operates during a jackpot game provided when a special symbol is won in the lottery by the special symbol lottery means and enables winning of a game ball, and is provided in the game area, A through-chucker that can pass through the inside, a normal symbol lottery means for performing an electronic lottery related to a normal symbol when a game ball passes through the through-chucker, and an entrance of the start port An electric tulip that opens and closes when a normal symbol is won in the lottery by the normal symbol lottery means, and makes it easy to win a game ball at the start opening, the special symbol lottery means, Random number generating means for special symbols for generating random numbers, and random numbers for special symbols for acquiring one random number among the random numbers generated by the random number generating means for special symbols when the game ball is won at the start opening A determination table used for determining whether or not the random number acquired by the acquisition means and the special symbol random number acquisition means is per the special symbol, the special symbol low having a low probability of winning per the special symbol A probability determination table, and a special symbol high probability determination table having a higher probability of winning per special symbol than the special symbol low probability determination table. The means obtains a normal symbol random number generator for generating a random number, and obtains one random number from random numbers generated by the normal symbol random number generator when the game ball passes through the through chucker. In a pachinko machine having a random number acquisition unit for symbols and a normal symbol determination table used for determining whether or not the random number acquired by the random number acquisition unit for normal symbols is per said normal symbol, As an opening / closing pattern of the electric tulip when having a normal hit and at least two types of hits per probability variation different from the normal hit, and winning / winning the normal symbol, with a predetermined number of times of opening and opening time. A normal opening / closing pattern to be opened and closed, which is more advantageous to the player than the normal opening / closing pattern, A first mode in which the special symbol low probability determination table and the normal opening / closing pattern are used as a gaming mode, wherein at least one of the release times has an advantageous opening / closing pattern that is advantageous to the player, and the special symbol A high probability determination table, a second mode in which the advantageous opening / closing pattern is used, the special symbol high probability determination table, a third mode in which the normal opening / closing pattern is used, the special symbol low probability determination table, and , And a fourth mode in which the advantageous opening / closing pattern is used, and when the winning game is won in the first mode, the second game is completed when the jackpot game ends. The mode is changed, and the game in the second mode is performed up to the upper limit of the first game number. If the player wins the normal win within the number of games, the game shifts to the first mode when the jackpot game ends. On the other hand, if the player wins the odds of change within the first game, the jackpot game When the game ends, the game in the second mode is performed again with the first number of games as the upper limit, and if the winning of the special symbol is not made within the first number of games, the mode shifts to the third mode. If the game is won in the third mode, the game is shifted to the fourth mode when the jackpot game is over, and the second number of games is greater than the first number of games. It was set as the structure by which the game in the said 4th mode is performed to the upper limit.

  In the present invention, as an opening / closing pattern of the electric tulip, a normal opening / closing pattern and an advantageous opening / closing pattern are provided. The normal opening / closing pattern is a pattern that opens and closes at a predetermined opening number (for example, once) and opening time (for example, 0.5 seconds). On the other hand, the advantageous opening / closing pattern is an opening / closing pattern that is more advantageous to the player than the normal opening / closing pattern. Specifically, at least one of the number of times of opening and the opening time predetermined in the normal opening / closing pattern is a game It is advantageous for the person.

  Here, the “advantage to the player” will be described in detail. If the electric tulip opens and closes more times (for example, twice) than the predetermined number of times of opening in the normal opening / closing pattern, the game ball wins the electric tulip. This is advantageous for the player. Therefore, if the opening / closing pattern is set so that the number of times of opening is larger than the normal opening / closing pattern, the advantageous opening / closing pattern of the present invention is obtained. In addition, if the opening time is longer than the time determined by the normal opening / closing pattern (for example, 3 seconds), the electric tulip is opened for a long time, so the possibility that the game ball wins the electric tulip is increased. Therefore, it is advantageous for the player. Therefore, the opening / closing pattern set so that the opening time is longer than the normal opening / closing pattern is also included in the concept of the advantageous opening / closing pattern of the present invention. Of course, the advantageous opening / closing pattern of the present invention also includes a case where the number of times of opening is large and the opening time is long (for example, it is opened twice for 3 seconds).

  Also in the present invention, when the winning combination is won in the first mode, the game shifts to the second mode when the jackpot game is over. The game in the second mode is performed up to the first number of games (for example, 10 times), and if it is not won per special symbol (per normal and probable) during this time, the game shifts to the third mode. . Then, when the normal winning is won in the third mode, the mode is shifted to the fourth mode, and the second mode number of games (for example, 100 times) larger than the first number of game times is shifted to the fourth mode.

  Here, in order to shift to the third mode, in the second mode, the special symbol lottery means does not win the special symbol within the first number of games. In other words, only the first number of games is won. The condition is to continue to lose. Only when this condition is achieved, the mode can be shifted to the third mode. Since the condition for shifting to the fourth mode is to win a normal win in the third mode, in order to shift to the fourth mode, first, in the second mode, the winning is per special symbol within the first number of games. It is a major premise not to do.

  The fourth mode is a mode in which a special symbol low probability determination table and an advantageous opening / closing pattern are used, and when winning per normal symbol, the number of times the electric tulip is opened increases or the opening time becomes longer. Or both, making it easy to win game balls in electric tulips. Therefore, in the fourth mode, it can be said that the game ball can be won at the starting port without almost reducing the game ball, which is one of advantageous states for the player. In addition, since the fourth mode is a game mode that is performed with the second game count higher than the first game count as the upper limit, it is still more advantageous for the player.

  In order to shift to the fourth mode advantageous to the player in this way, as described above, first, in the second mode, it is a condition that the special symbol lottery means does not win a special symbol in the electronic lottery means. In the second mode, the player plays the game while praying in the hope of not winning (losing) within the first number of games. This is the opposite of enjoying a game while wishing to win within a predetermined number of games.

  In other words, in the present invention, in order to shift to the third mode and the fourth mode, the condition that the special symbol is not won within the first number of games in the second mode is set. If you did not win within the short-time mode, the game was stopped when the predetermined number of games ended, whereas in the present invention, if you did not win within the predetermined number of games Since the mode is switched to a mode advantageous to the player, a game after a predetermined number of games is more attractive to the player. Therefore, even if the second mode is finished, the fun is still maintained and the game is not bored. In addition, when the mode is shifted from the second mode to the third mode or the fourth mode, it is advantageous to the player. Therefore, the player continues the game even after the second mode is finished, and the pachinko machine is operated. It greatly contributes to preventing the decrease.

  In addition, in the case of the pachinko machine having the above configuration, in the fourth mode, when the winning game is won within the second number of games, the game shifts to the third mode when the jackpot game ends, In the case of winning in the normal mode in the 4 mode, the game in the fourth mode is performed again when the jackpot game is completed, and in the fourth mode, the special symbol is played within the second number of games. If not won, the first mode may be entered.

  Here, when the fourth mode and the first mode are compared, the same special symbol low probability determination table is used as the determination table used to determine whether or not the symbol is per special symbol. In the fourth mode, the normal symbol high probability determination table is used in the fourth mode, while the normal symbol low probability determination table is used in the first mode. Alternatively, as the opening / closing pattern of the electric tulip, the advantageous opening / closing pattern is used in the fourth mode, whereas the normal opening / closing pattern is used in the first mode. Therefore, it can be said that the first mode is a more disadvantageous mode for the player than the fourth mode.

  Therefore, in the pachinko machine configured as described above, if the special symbol is not won within the second number of games in the fourth mode, the game shifts to the first mode which is disadvantageous than the fourth mode (falls). It is important how to win a special symbol within the second number of games. Thus, according to this structure, since it can transfer from 4th mode to 1st mode, a game comes out sharply and the preference improves.

  Further, in the pachinko machine having the above-described configuration, when the second number of games is M times and the probability per special symbol of the special symbol low probability determination table is 1 / N, the relation of N <M is satisfied. You may set as follows. With this configuration, there is an advantage that the probability of hitting a special symbol within the second number of games increases, the game in the fourth mode can be greatly expected, and the fun is increased.

  In addition, the pachinko machine having the above-described configuration further has a special probability variation that is more advantageous to the player than the probability variation as the special symbol, and the jackpot game is provided at the time of the special probability variation. If the special jackpot game is won in the game in the first mode, the mode may be shifted to the third mode when the special jackpot game ends. If comprised in this way, if it wins per special probability change in a 1st mode, since it can transfer to a 3rd mode immediately, premier gameability can be ensured.

  In addition, in the case of the pachinko machine having the above-described configuration, when the winning combination is won in the third mode, when the jackpot game is over, the game is performed again in the third mode, and the special mode is performed in the third mode. Even in the case of winning in the probability change, the game in the third mode may be performed again when the special jackpot game ends. In addition, about the pachinko machine of the said structure, when winning normally in 1st mode, it is preferable to continue staying in 1st mode as it is and not to transfer to another mode.

  According to the present invention, in the second mode, the mode is shifted to an advantageous mode on condition that no special symbol is won in the electronic lottery by the special symbol lottery means within the first number of games. However, the game will continue to be interesting and the game will not be bored, and it will also be effective in preventing the decline in operation.

In this case, a special symbol reserved ball memory (not shown) for storing the acquired random number as a special symbol reserved ball random number, and a special symbol low probability determination table 115 having a low probability of winning per special symbol as a determination table. And a special symbol high probability determination table 116 having a higher probability of winning per special symbol than the special symbol low probability determination table 115, and a special symbol for selecting one of these two determination tables according to the game mode. A determination table selection unit 114.

  On the other hand, the normal symbol lottery unit 160 includes a normal symbol random number generator (normal symbol random number generator) 161 having the same configuration as that of the random numbers generated by the special symbol random number generator 111 but the through-chucker 21. When the game ball passes through (when the detection signal from the through chucker detection sensor 46 is input to the main control processing unit 11), one random number acquisition unit for normal symbols (ordinary) is acquired (latched). Symbol random number acquisition means) 162, a normal symbol success / failure determination unit 163 that determines whether or not the random number acquired by the normal symbol random number acquisition unit 162 is per normal symbol, and a normal symbol When the normal symbol is changing when the random number acquisition unit 162 acquires the random number, the acquired random number is stored as a normal symbol reserved ball random number. (Not shown), as a determination table, a normal symbol low probability determination table 165 having a low probability of winning per normal symbol, and a normal symbol having a higher probability of winning per normal symbol than the normal symbol low probability determination table 165 A high probability determination table 166 and a normal symbol determination table selection unit 164 that selects one of these two determination tables according to the game mode are provided.

  The electric tulip operation control unit 170 performs control so that the solenoid of the electric tulip 49 is energized and opened / closed based on a command won per normal symbol in the electronic lottery performed by the normal symbol lottery unit 160. In the pachinko machine P according to the first embodiment, when a normal symbol is won once per symbol, the blade member of the electric tulip 49 is controlled to be opened only once for 2 seconds regardless of the game mode. The jackpot game control unit 150 controls the attacker device 41 to open and close a predetermined number of rounds according to the type of special symbol.

  Next, a sub-control unit that controls various devices in response to a command from the main control processing unit 11 will be described. The effect display control unit 12a is provided on the back surface of the game board 3 via a support member or the like, and controls the effect display device 34 and other effect devices (such as LED devices) according to the processing information generated by the main control processing unit 11. It is a device that performs. Specifically, the effect display control unit 12a receives the command of the lottery result (any one of the normal hit, the probability variation, the special probability variation, or the loss) determined by the special symbol success / failure determination unit 113 from the main control processing unit 11, and the symbol In response to the special pattern variation pattern commands determined by the variation pattern determination unit 130, based on these commands, an effect mode selection unit (not shown) includes a plurality of types of effect modes stored in the ROM. A predetermined production mode is selected from the above. The effect display control unit 12a controls the effect display device 34 to display the selected effect mode. Further, when the effect display control unit 12a receives a command indicating that the reserved ball random number is stored in the special symbol reserved ball memory, the effect display control unit 12a displays the reserved ball information (white star mark) on the effect display device 34. It also has.

  The special symbol display control unit 12b displays the special symbol based on the special symbol command determined by the special symbol determination unit 120 of the main control processing unit 11 and the special symbol variation pattern command determined by the symbol variation pattern determination unit 130. The special symbol determined by the special symbol determination unit 120 is displayed in such a manner that the device 17 is stopped after changing the special symbol.

  On the other hand, the normal symbol display control unit 12f receives a lottery result command related to the normal symbol by the normal symbol lottery unit 160, displays the normal symbol on the normal symbol display device 22 based on the command, and displays it in a manner of stopping. It is controlled to do. The basic symbol display control unit 12f has substantially the same basic configuration of display control, although the symbol to be displayed is different from the display control by the special symbol display control unit 12b described above.

  The lamp control processing unit 12c receives commands from the main control processing unit 11 and performs lighting control of various lamps and electrical decorations. The voice control processing unit 12d receives a command from the main control processing unit 11 and controls the operation of the speaker and the like.

  The payout control processing unit 12e receives a signal from the CR unit and controls the prize ball paying device 14 so as to lend out a game ball to the player. In addition, the payout control processing unit 12e receives a payout command from the main control processing unit 11 to receive a predetermined number of balls. The prize ball payout device 14 is controlled so as to pay out the prize ball to the player. The prize ball payout device 14 includes a sprocket (not shown) in which notches are formed for holding game balls one by one, and a motor (not shown) for rotating the sprocket. By controlling the rotation of the motor, the required number of prize balls can be paid out. Specifically, when the start winning opening detection sensor 43, the general winning opening detection sensor 44, the big winning opening detection sensor 45, etc. detect the passage of the game ball, the winning ball payout device 14 passes through the main control processing section 11. The game ball is paid out based on the received command.

  The firing control processing unit 13 is a device that controls the operation of the launching device 9 according to the rotation amount of the handle 7. More specifically, control processing is performed such as energizing the launching device 9, stopping energization, or changing the energization current. The launch control processing unit 13 is connected to the payout control processing unit 12e, and a launch stop signal is received when the CR unit is not connected.

  Next, the flow of the game of the pachinko machine P according to the first embodiment will be described with reference to FIGS. FIG. 5 and FIG. 6 are flowcharts for explaining the game flow of the pachinko machine P according to the first embodiment, and FIG. 7 is a normal game after the big hit game depending on the game mode and the type of special symbol won. It is explanatory drawing which showed how many games the symbol high probability determination table is used.

  First, the outline of the game specifications in the first embodiment will be described. The lottery probability of a special symbol is 1/62 .2 at a low probability (winning probability per special symbol using the special symbol low probability determination table 115). 8. When the probability is high (the winning probability per special symbol using the special symbol high probability determination table 116), it is 1 / 10.4. On the other hand, the lottery probability of the normal symbol is 1/7 when the probability is low (winning probability per normal symbol using the normal symbol low probability determination table 165), and when the probability is high (the normal symbol high probability determination table 166 is The winning probability per regular symbol used is 1/1.

  The winning probability per special symbol is 1 / 62.8 (N = 62.8) at a low probability, and is 100 times (M = number of games in the heaven mode described later (second game number)). 100) is set such that N <M.

  In addition, if you win per special symbol, you will be offered a jackpot game. As shown in Fig. 7, if you win per regular symbol, you will receive a jackpot game. The number of rounds (when the attacker device 41 opens and closes a predetermined number of times is one round, the number of times this round is performed) is 5 rounds. It is predetermined as round.

  Next, the game mode of the pachinko machine according to the first embodiment will be described. The normal mode, which is the first mode, is a mode in which the special symbol low probability determination table 115 and the normal symbol low probability determination table 165 are used. This normal mode is a normal mode that is not particularly advantageous for the player because the probability of being per special symbol and the probability of being per normal symbol are both low.

  The challenge mode, which is the second mode, is a mode in which the special symbol high probability determination table 116 and the normal symbol high probability determination table 166 are used. In this challenge mode, the probability of being per special symbol and the probability of being per normal symbol are both high, which is a mode advantageous to the player compared to the normal mode. More specifically, since the normal symbol high probability determination table 166 is used, there is a high possibility that the electric tulip 49 is frequently opened per ordinary symbol. Therefore, the game balls are hardly reduced and can be awarded to the start winning opening 37. And since the special symbol high probability determination table 116 is used, there is a high possibility that it will be per special symbol. Therefore, it can be said that this is an advantageous mode in which it is easy to shift to the next jackpot game with almost no decrease in game balls. In this challenge mode, the upper limit of the number of games is set to 10 times (first game number).

  The heaven preparation mode, which is the third mode, is a mode in which the special symbol high probability determination table 116 and the normal symbol low probability determination table 165 are used. In this heaven preparation mode, since there is a high probability of winning per special symbol, the mode is more advantageous than the normal mode. More specifically, since the normal symbol low probability determination table 165 is used, the electric tulip 49 is unlikely to open frequently, so the number of game balls decreases, but the special symbol high probability determination table 116 Since it is used, it can be said that it is an advantageous mode that is easy to shift to a jackpot game per special symbol.

  The heaven mode, which is the fourth mode, is a mode in which the special symbol low probability determination table 115 and the normal symbol high probability determination table 166 are used. In this heaven mode, since the normal symbol high probability determination table 166 is used, there is a high possibility that the electric tulip 49 frequently opens per symbol. On the other hand, since the special symbol low probability determination table 115 is used, the probability of winning per special symbol is low, but the winning ball 37 is won with almost no decrease in game balls by opening and closing the electric tulip 49. Therefore, it can be said that this is an advantageous mode compared to the normal mode. In this heaven mode, the upper limit of the number of games is set to 100 (second game number).

  As described above, the pachinko machine P according to the present embodiment has a total of four game modes, and the transition to these game modes is controlled by the game mode transition control unit 150. Therefore, how to shift to these four game modes will be described in detail below. In the following explanation, there is a case where the term jackpot is used, but the jackpot mentioned here means a special symbol, and three types of hits, that is, a normal hit, a probability variable, and a special probability variable are jackpots. include.

  First, a game in the normal mode is performed (step S10), and the special symbol random number acquisition unit 112 receives a game ball from the start winning slot 37. Get one from Then, the special symbol success / failure determination unit 113 determines whether or not the random number is a big hit (per special symbol) (step S11). If it is not a big hit (No in step S10), the game in the normal mode is performed without providing the big hit game. On the other hand, if it is a big hit (Yes in step S11), a big hit game is executed by the big hit game control unit 140 (step S12). Specifically, in the case of normal hit and probability change, a 5-round jackpot game is provided, and in the case of special probability change, a 2-round jackpot game is provided (see FIG. 7). When the jackpot game ends, it is determined whether or not the jackpot type (special symbol type) is a normal jackpot (step S13).

  If it is a normal win (Yes in step S13), the game stays in the normal mode as it is and a game in the normal mode is performed. On the other hand, if it is not a normal hit (Yes in step S13), it is determined whether or not the type of jackpot was a special probability change hit (step S14). If it is a special probability change (Yes in step S14), the game mode transition control unit 150 suddenly shifts from the normal mode to the heaven preparation mode (step S19). On the other hand, when the type of jackpot is not a special probability change (No in step S14), the game mode transition control unit 150 shifts the game mode from the normal mode to the challenge mode (step S15). That is, when the type of jackpot is a probable hit, the mode shifts from the normal mode to the challenge mode.

  Here, as shown in FIG. 7, when a winning game is won in the normal mode, the game using the normal symbol high probability determination table 166 is set to be performed 10 times after the jackpot game. The mode transition control unit 150 manages the game mode so that the game in the challenge mode does not exceed 10 times. In this way, the game mode that becomes the transition destination after the jackpot game is associated with the number of times that the game can be played using the normal symbol high probability determination table after the jackpot game according to the type of jackpot (per special figure). It is. That is, in order to match the state of the game mode (game mode after transition) transferred by the game mode transition control unit 150, the type of jackpot under each game mode before transition and the normal symbol height in the game mode after transition The number of times the probability determination table 166 is used is determined in advance.

  Next, it is determined whether or not a big hit (per special symbol) has been made within the ten games (step S16). When the jackpot is won within 10 games (Yes in step S16), the jackpot game corresponding to the type of jackpot is provided as in step S12 (step S17). Then, the type of jackpot is determined (step S18), and if the type of jackpot is normal (Yes in step S18), the game mode transition control unit 150 shifts (falls) the game mode to the normal mode. . In the normal mode after the transition, the normal symbol high probability determination table 166 is not used. Therefore, when the normal mode is won in the challenge mode before the transition to match the game mode after the transition, as shown in FIG. The number of games in which the normal symbol high probability determination table 166 after the jackpot game is used is set to zero.

  On the other hand, if the jackpot type is not a normal hit (No in step S18), the process returns to step S14 to determine whether or not the jackpot type is a special chance variable, and if the jackpot type is a special chance variable. The game moves to the heaven preparation mode, but if it is a probable hit, the game in the challenge mode is again performed up to 10 times. Here, referring to FIG. 7, when winning per chance change in the challenge mode, the number of games in which the normal symbol high probability determination table 166 is used is set to 10 times. This is because the game in the challenge mode is again performed up to 10 times. Thus, in order to secure the game in the game mode after the transition, settings as shown in FIG. 7 are made. Hereinafter, since it is the same in each game mode, description of comparison between the transition of the game mode and FIG. 7 is omitted.

  Returning to the description of the game flow, when the game was played 10 times in the challenge mode, but it was not a big hit within the 10th time (that is, when the special symbol lottery unit 110 continued to draw a lose) No in step S16, and shifts to the heaven preparation mode (step S19). As shown in FIG. 6, in the game in the heaven preparation mode (step S19), the special symbol lottery unit 110 performs the electronic lottery related to the special symbol in response to the game ball winning in the start winning opening 37, and whether or not it is a big hit Whether or not is determined for each game (step S20). If it is not a big hit (No in step S20), the game is repeated until the big hit in the heaven preparation mode, but if it is a big hit (Yes in step S20), as in step S12, 5 depending on the type of the big win A round or two round jackpot game is played (step S21). When the jackpot game ends, it is determined in step S22 whether the type of jackpot is a probability change or a special probability change. When the type of jackpot is either probable hit or special probability change (Yes in step S22), the game mode transition control unit 150 controls the game mode transition so as to repeat the game in the heaven preparation mode again. The

  On the other hand, when the type of jackpot is normal (No in step S22), the game mode shift control unit 150 shifts the game mode to the heaven mode (step S23). The game in the heaven mode is performed up to the second game count of 100 times. In step S24, it is determined whether or not a big hit is made within 100 games in this heaven mode. If the jackpot is won within 100 times (Yes in step S24), a five-round or two-round jackpot game is executed according to the type of jackpot (step S25). When the jackpot game ends, it is determined whether the type of jackpot is a probability change or a special probability change (step S26).

  If it is either the probability variation or the special probability variation (Yes in step S26), the game mode transition control unit 150 shifts the game mode to the heaven preparation mode. On the other hand, when the jackpot is a normal hit (No in step S26), the game mode transition control unit 150 maintains the game mode in the heaven mode. That is, if the normal winning is won within 100 games in the heaven mode, the processing from step S23 to step S26 is repeated, and the heaven mode is looped. On the other hand, if the game has been played 100 times in the heaven mode, but the jackpot is not won (No in step S24), the mode is changed (falls) to the normal mode.

  In the present embodiment, as described above, the jackpot probability (1 / N) in the heaven mode and the number of games M in the heaven mode are N = 62.8 and M = 100, so that N <M It has become a relationship. Therefore, in terms of the numerical value, the probability is that it will be a big hit once in 62.8 times, so the calculation will be a big hit once within 100 games in the heaven mode. Therefore, if you switch to heaven mode, you will have a big chance in heaven mode with a high probability, and will tend to be in a gaming state that goes back and forth between heaven preparation mode and heaven mode, and conversely, without winning a jackpot within 100 times If it falls to the mode (No in step S24), it can be said that there are relatively few. In other words, reaching the heaven mode is very advantageous for the player.

  Incidentally, the probability that the jackpot is repeated within 100 times in the heaven mode in the first embodiment, the so-called consecutive resort rate, is obtained as follows. In other words, substituting N = 62.8 and M = 100 into the formula 1- (1-1 / N) ^ M yields the ratio of consecutive resorts = 79.91%, and within the heaven mode with a high probability of about 80% It is a specification that jackpots are consecutive.

  As described above, according to the pachinko machine according to the first embodiment, in the case of a game in the challenge mode, if the player does not win a jackpot within 10 times (continues to lose), the heaven preparation mode Migrate to The transition to the heaven mode is possible only after the transition to the heaven preparation mode. Since the normal symbol high probability determination table 166 is used in the heaven mode, the player repeats the game in the heaven mode with almost no reduction in the number of game balls as long as the normal hit is kept within 100 times in this heaven mode. It can be done and many prize balls can be won.

  In other words, in the present embodiment, it is possible to acquire the right to shift to a game mode advantageous to the player by continuing to pull out in the game in the challenge mode. After the game ends, the game will become more and more interesting, and even after the challenge mode ends, the fun will continue and the game will not be bored. In addition, since the player is more advantageous after shifting to the heaven preparation mode, the game is less likely to be stopped even when the challenge mode is ended, and the operation of the pachinko machine is not reduced.

  Furthermore, since the special probability variation is provided, the game may be shifted directly to the heaven preparation mode without going through the challenge mode, so that an unexpected game can be realized and the preference is enhanced.

  Next, a second embodiment of the present invention will be described with reference to the drawings. Components having the same configurations as those of the first embodiment will be denoted by the same reference numerals, and description thereof will be omitted. The description will focus on the differences from the first embodiment. The pachinko machine P according to the second embodiment is different from the first embodiment in the configuration relating to the electronic lottery related to the normal symbol and the configuration for operating the electric tulip.

  Specifically, as illustrated in FIG. 8, in the second embodiment, the normal symbol lottery unit 160 includes one normal symbol determination table 167. That is, the probability of the electronic lottery related to the normal symbol is the same in any game mode. On the other hand, the electric tulip operation control unit 170 includes a normal opening / closing pattern 171 and an advantageous opening / closing pattern 172 as patterns for opening and closing the electric tulip 49. The normal opening / closing pattern 171 is a pattern in which the electric tulip 49 opens once with an opening time of 0.5 seconds. On the other hand, the advantageous opening / closing pattern 172 is a pattern in which the electric tulip 49 is opened twice with an opening time of 3 seconds (a total of 6 seconds is opened). In other words, even if the same normal symbol is won, the advantageous opening / closing pattern is longer than the normal opening / closing pattern 171 because the electric tulip 49 opens for a long time, and thus the probability of winning the game ball to the electric tulip 49 is high. It is advantageous.

  Next, the flow of the game in this embodiment will be described with reference to FIGS. 9 and 10 are flowcharts for explaining the game flow of the pachinko machine P according to the second embodiment.

  First, the outline of the game specifications in the present embodiment will be described. As in the first embodiment, the lottery probability of the special symbol is 1 / 62.8 at the low probability and 1/10. At the high probability. It is four. On the other hand, the normal symbol lottery probability is the same (1/7) in any game mode, but the open / close pattern of the electric tulip 49 when the normal symbol is won is a disadvantage for the player. The configuration is different from that of the first embodiment in that there are two patterns, a pattern 171 and an advantageous opening / closing pattern 172 advantageous to the player.

  The winning probability per special symbol is 1 / 62.8 (N = 62.8) at the low probability, and the relationship of the numerical value of 100 times (M = 100), which is the number of games in the heaven mode described later, is , N <M is the same as in the first embodiment. Further, since the contents (number of rounds) of the jackpot game are the same as those in the first embodiment, detailed description thereof is omitted.

  Further, regarding the game mode according to the second embodiment, the normal symbol low probability is determined for the game modes (the normal mode and the heaven preparation mode) in which the normal symbol low probability determination table 165 is used in the first embodiment. The normal open / close pattern 171 is used instead of the determination table 165, and the game mode (challenge mode and heaven mode) in which the normal symbol high probability determination table 166 is used is advantageous instead of the normal symbol high probability determination table 166. If the opening / closing pattern 172 is used, the game mode according to the second embodiment is achieved.

  That is, the normal mode which is the first mode is a mode in which the special symbol low probability determination table 115 and the normal open / close pattern 171 are used. The challenge mode, which is the second mode, is a game mode in which the special symbol high probability determination table 116 and the advantageous opening / closing pattern 172 are used. In this challenge mode, since the advantageous opening / closing pattern 172 is used, the electric tulip 49 is opened per unit time for a long time, so the possibility that the game ball will win the start winning opening 37 increases, and the player This is an advantageous game mode. The heaven preparation mode which is the third mode is a mode in which the special symbol high probability determination table 116 and the normal opening / closing pattern 171 are used. The heaven mode, which is the fourth mode, is a mode in which the special symbol low probability determination table 115 and the advantageous opening / closing pattern 172 are used. In this heaven mode, the advantageous opening / closing pattern 172 is used, so that the electric tulip 49 is opened for a long time per symbol and there is a high possibility that the game ball will win the start winning opening 37.

  Thus, the pachinko machine P according to the second embodiment similarly has a total of four game modes, and the transition to these game modes is controlled by the game mode transition control unit 150. In the following, a description of the transition of the game mode will be simply added.

  First, a game in the normal mode is performed first (step S110), and the random number generated by the special symbol random number generating unit 111 is generated by the special symbol random number generating unit 111 when the game ball is won in the start winning opening 37. Get one from the list. Then, the special symbol success / failure determination unit 113 determines whether or not the random number is a big hit (per special symbol) (step S111). If it is not a big hit (No in step S110), the game in the normal mode is performed as it is without providing the big hit game. On the other hand, when it is a big hit (Yes in Step S111), the big hit game is executed by the big hit game control unit 140 (Step S112). Specifically, in the case of the normal hit and the probability change, a 5-round jackpot game is provided, and in the case of the special probability change, a 2-round jackpot game is provided. When the jackpot game ends, it is determined whether or not the jackpot type (type per special symbol) is a normal hit (step S113).

  If it is a normal win (Yes in step S113), the game stays in the normal mode as it is and a game in the normal mode is performed. On the other hand, if it is not a normal hit (Yes in step S113), it is determined whether or not the type of jackpot was a special probability change (step S114). When it is a special probability change (Yes in Step S114), the game mode transition control unit 150 suddenly shifts the game mode from the normal mode to the heaven preparation mode (Step S119). On the other hand, if the type of jackpot is not a special probability change (No in step S114), the game mode transition control unit 150 shifts the game mode from the normal mode to the challenge mode (step S115).

  Next, it is determined whether or not a big hit (per special symbol) has been made within 10 games in the challenge mode (step S116). When the jackpot is won within 10 games (Yes in step S116), the jackpot game corresponding to the type of jackpot is provided as in step S112 (step S117). Then, the type of jackpot is determined (step S118), and if the type of jackpot is normal (Yes in step S118), the game mode transition control unit 150 shifts (falls) the game mode to the normal mode.

  On the other hand, if the jackpot type is not a normal hit (No in step S118), the process returns to step S114 to determine whether or not the jackpot type is a special chance variable. Although the mode is shifted to the preparation mode, when the chance is a probability change, the game in the challenge mode is again performed up to 10 times.

  If the game was played 10 times in the challenge mode, but it was not a big hit within 10 times (that is, if the lottery continued to be drawn in the electronic lottery by the special symbol lottery unit 110), No in step S116 Then, the process proceeds to the heaven preparation mode (step S119). As shown in FIG. 10, in the game in the heaven preparation mode (step S119), the special symbol lottery unit 110 performs the electronic lottery related to the special symbol in response to the game ball winning in the start winning opening 37, and whether or not the big win It is determined for each game whether or not (step S120). If it is not a big hit (No in step S120), the game is repeated until the big hit in the heaven preparation mode, but if it is a big win (Yes in step S120), the game will be 5 according to the type of the big win as in step S112. A round or two round jackpot game is played (step S121).

  When the jackpot game is over, it is determined in step S122 whether the type of jackpot is a probability change or a special probability change. When the type of jackpot is either probable or special odds (Yes in step S122), the game mode transition control unit 150 controls the transition of the game mode so that the game in the heaven preparation mode is repeated again. The

  On the other hand, when the type of jackpot is normal (No in step S122), the game mode shift control unit 150 shifts the game mode to the heaven mode (step S123). The game in the heaven mode is performed up to the second game count of 100 times. Then, in step S124, it is determined whether or not a big hit is made within 100 games in this heaven mode. If the jackpot is won within 100 times (Yes in step S124), a five-round or two-round jackpot game is executed depending on the type of jackpot (step S125). When the jackpot game ends, it is determined whether the type of jackpot is a probability change or a special probability change (step S126).

  If it is either the probability change or the special probability change (Yes in step S126), the game mode transition control unit 150 shifts the game mode to the heaven preparation mode. On the other hand, when the big hit is the normal hit (No in step S126), the game mode transition control unit 150 maintains the game mode in the heaven mode. That is, if the normal winning is won within 100 games in the heaven mode, the processing from step S123 to step S126 is repeated, and the heaven mode is looped. On the other hand, if the game has been played 100 times in the heaven mode, but the jackpot is not won (No in step S124), the mode will be shifted to the normal mode (falling down).

  As described above, also in the pachinko machine according to the second embodiment, in the same way, in the case of a game in the challenge mode, if the jackpot is not won within 10 times (continuing to lose), the heaven preparation mode Migrate to The transition to the heaven mode is possible only after the transition to the heaven preparation mode. Since the advantageous opening / closing pattern 172 is used in the heaven mode, the player can repeatedly play the game in the heaven mode without reducing the number of game balls as long as the normal hit is continued within 100 times in the heaven mode. , You can win many prize balls.

  In other words, in the second embodiment, it is possible to acquire the right to shift to the game mode advantageous to the player by continuing to pull out the game in the game in the challenge mode. The game after the game ends will become more and more interesting, and even after the challenge mode ends, the fun will continue and the game will not be bored. In addition, since the player is more advantageous after shifting to the heaven preparation mode, the game is less likely to be stopped even when the challenge mode is ended, and the operation of the pachinko machine is not reduced.

  In the game mode in which the normal symbol high probability determination table 166 is used in the above-described embodiment, the opening / closing pattern of the electric tulip 49 may be set to the advantageous opening / closing pattern 172. That is, in the challenge mode (the second mode and the fourth mode), a mode in which both the normal symbol high probability determination table and the advantageous opening / closing pattern are used may be set. According to such a configuration, it is possible to provide a gaming state that is more advantageous to the player with respect to the normal symbol. In other words, since there is a high probability of winning per ordinary symbol in the electronic lottery related to ordinary symbols, the electric tulips frequently open and close, and the opening time and number of times of opening of the electric tulips will be more than usual, so it will be a starting prize. The possibility that a game ball wins is further increased, which is more advantageous to the player.

  Further, a game mode in which the normal symbol high probability determination table 166 is used, a game mode in which the advantageous opening / closing pattern 172 is used, or a game in which both the above-described normal symbol high probability determination table and the advantageous opening / closing pattern are used. In the mode, a configuration may be adopted in which the time for variably displaying the result of the electronic lottery relating to the normal symbol (the normal symbol fluctuation time) is shortened. According to such a configuration, the time until the lottery result of the normal symbol is determined is shortened, and even more electronic lotteries related to the normal symbol can be received even in the same time, so that a more advantageous state can be created for the player. This will increase the game's preference.
