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 a game ball launched toward the game area wins the specific prize opening, an electronic lottery is performed, and the special symbol display device displays a mode in which the special symbol is changed and then stopped. The result of the electronic lottery is reported. At the same time, an effect corresponding to the result of the electronic lottery is displayed on the effect display device to entertain the player. If it is per the result of the electronic lottery, a special symbol indicating that it is a win on the special symbol display device is displayed, and an indication that the win is on the effect display device is displayed, which is advantageous for the player. Transition to a big jackpot gaming state. 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.

  Such a pachinko machine is generally provided with two types of hits, that is, a normal hit and a probability change that is more advantageous to the player than the normal hit. The normal win is the one that returns to the normal state after the jackpot gaming state is finished, and the probable hit is a gaming state (probability variation gaming state) that has a high probability of winning in the electronic lottery even if the jackpot gaming state is finished. It will be. Therefore, the player plays the game while expecting a more probable hit than the normal hit.

  By the way, in recent years, pachinko machines that have a hit called sudden probability change in addition to normal hit and probability change have appeared. This sudden probability change is the same as the probability change in that the game state with a high probability of winning in the electronic lottery (probability variation game state) is transferred after the jackpot game state ends, but the content of the jackpot game state is a probability change. Is different. More specifically, in the jackpot gaming state per probability variation, the number of times the attacker device is opened and closed is, for example, 15 (round), whereas sudden probability variation is, for example, two. Further, the time for the attacker device to open once is, for example, 30 seconds at maximum per probability change, but is less than 1 second, for example, per sudden change.

  As described above, the sudden probability variation is set so that the big hit gaming state is completed in a very short time compared to the probability variation. Therefore, even if the player suddenly hits the probability change, if the player is looking at the effect displayed on the effect display device, the attacker device will open and close soon and the jackpot game state will end, and suddenly the probability display state will change to the effect display device The situation that it is displayed will arise. The game characteristics using this sudden probability variation are in a state of probability fluctuation for a player who is playing only with a pachinko machine that has only two types of hits, normal and probability variation. As a result, it has recently been widely accepted by players as being surprising and interesting.

  However, this sudden probability change has the unexpectedness and interest of the game that the player is in a state of probability variation while the player is not aware of the jackpot gaming state (opening / closing of the attacker device), and the attacker device opens and closes. If the player notices what is being done, the fun will be lost. In other words, how to prevent the player from noticing that the attacker device is open / closed can be said to be the lifeline of sudden change. Therefore, for example, there is a technique described in Patent Document 1 as a technique for not allowing the player to notice the opening and closing of the attacker device when a sudden probability change occurs.

  In other words, in the pachinko machine described in Patent Document 1, the player suddenly shifts to the jackpot gaming state based on the probability variation while attracting the player to the production of the super reach, and the player does not notice the operation of the attacker device. I am devised like this. That is, in the case of a sudden probability change, during the super reach effect, the special symbol is changed for a predetermined time and then stopped, and the attacker device is opened and closed twice.

Japanese Patent Laying-Open No. 2005-160740 (paragraphs 0069 to 0079, FIG. 1, etc.)

  However, in the above conventional technique, a skilled player can easily grasp whether or not it is a sudden probability change by checking the opening / closing operation of the attacker device when a predetermined time elapses during the production of the super reach. Can be done. Therefore, it is difficult to prevent the player from noticing that the player has suddenly been struck by such a device, and it is actually not a surprising game.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pachinko machine that is less likely to be noticed suddenly by a player.

  In order to achieve the above object, the present invention is based on 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. Electronic lottery means for performing lottery, special symbol display device for displaying a lottery result by the electronic lottery means, special symbol determining means for determining a special symbol to be displayed on the special symbol display device from a plurality of types, the electronic After changing the special symbol, an effect display device that displays a predetermined effect mode based on the lottery result by the lottery means, an effect mode selection unit that selects an effect mode to be displayed on the effect display device from a plurality of types, and Special symbol display control means for controlling the display of the special symbol display device so as to stop the special symbol determined by the special symbol determination means, and the effect mode selected by the effect mode selection means Effect display control means for controlling the display to be displayed on the effect display device, and game control means for shifting to a special game advantageous to the player as compared to the normal game when the lottery result by the electronic lottery means is a win In a pachinko machine equipped with an attacker device that operates when the game is shifted to the special game and enables winning of a game ball, as the hit, the sudden probability variation and the jackpot that is more advantageous to the player than the sudden probability variation The plurality of types of production modes include a common production mode selected by the production mode selection means for any of the lottery results of sudden probability change, jackpot, and loss. This common effect mode includes the first half common effect mode displayed between the start of display on the effect display device and the elapse of the first time, and the first time The second half common effect mode displayed from when the display has elapsed until the second time elapses is configured as a continuous effect. The game is shifted to a winning game and the probability-changing game having a higher probability of winning the lottery result by the electronic lottery means than the normal game when the game is suddenly changed. A jackpot game that is more advantageous to the player than a chance game, and the sudden chance game is set so that the operation time of the attacker device is shorter than the jackpot game. As a game process performed during the transition to the game per probability change, adjustment of the waiting time from the sudden transition to the game per probability change until the attacker device operates A pre-process for performing the operation, an operation process for the attacker device following the pre-process, and a process performed following the operation process for the attacker device, the game being performed suddenly after the operation of the attacker device is completed. The game process includes a processing pattern in which the time required for the process is set to the same time as the second time. A processing pattern selection means for selecting any of the processing patterns based on the type of the special symbol determined by the special symbol determination means from a plurality of processing patterns including the processing pattern, wherein the lottery result by the electronic lottery means In the case of sudden probability change, first, the special symbol display control means causes the special symbol display device to change the special symbol, and the effect display control means Of the common effect modes selected by the effect mode selection means, the first half common effect mode is displayed on the effect display device, and when the first time has elapsed, the special symbol display control unit is configured to display the special symbol display. The special symbol changing in the device is stopped at the special symbol determined by the special symbol determination means, and the game control means shifts to the game per sudden change and performs the game processing, and the effect display When the control means causes the effect display device to display the second half common effect mode until the second time elapses, and the lottery result by the electronic lottery means is a big hit, first, the special symbol display control means While changing the special symbol in the symbol display device, the effect display control unit is the previous of the common effect modes selected by the effect mode selection unit After the first half common effect mode is displayed on the effect display device, the second half common effect mode is displayed as a continuous effect until the second time has elapsed, and the game process during the display of the second half common effect mode is The configuration is such that the processing pattern is executed by the processing pattern in which the same time as the second time selected by the processing pattern selection means is set.

  The pachinko machine according to the present invention has a sudden probability variation and a jackpot as the winning, and when the winning is a sudden probability variation as a result of the electronic lottery, a predetermined rendering is being displayed on the rendering display device. If the game suddenly shifts to a probable win game and wins a jackpot, the jackpot game is advantageous to the player after a predetermined effect is displayed on the effect display device. And, even if the lottery result is either a sudden win or a big win, while the first half common production mode and the second half common production mode are displayed on the production display device as a continuous production, and the first half common production mode is displayed The special symbols are changed and stopped at the same time, and the game process is suddenly executed with the processing pattern corresponding to the special symbols at the same time as the time when the second half common effect mode is displayed. Therefore, it is possible to make it difficult for the player to notice the operation of the attacker device that is performed during the game when the player suddenly changes.

  According to the pachinko machine of the present invention, even if the result of the electronic lottery suddenly becomes a probable hit or a big win, the effect display device displays the first half common effect mode and the second half common effect mode as an effect, The special symbol changes and stops while the first half common effect mode is displayed, and is the same time as the time when the second half common effect mode is displayed, with a processing pattern corresponding to the special symbol. Since the game processing is executed suddenly per probability change, it is possible to make it difficult for the player to notice the operation of the attacker device performed during the game.

Next, the configuration of the pachinko machine P will be described in detail with reference to FIGS.

  The game board 3 has a game area 31 on the board surface, and the game area 31 can be observed from the glass plate 10 after being attached to the front frame 2. The game area 31 is partitioned and formed into a substantially circular shape by a guide rail 32 for sliding the game ball and a game ball regulating rail 33, and the game ball launched by the launching device 9 flows down in the game area 31. To do. Further, in the game area 31, a special symbol display device 17, an effect display device 34, a stage 36, a start winning opening (start opening) 37, a general winning opening 38, an out opening 39, and a game nail ( (Not shown), a windmill (not shown), an attacker device 41, and the like are provided.

  The effect display device 34 is provided in a substantially central portion of the game board 3 and displays a predetermined effect mode based on the result of an electronic lottery performed when a game ball wins a winning prize opening 37. In this embodiment, a liquid crystal display device is used. The special symbol display device 17 is for displaying the result of the electronic lottery performed when the game ball wins at the start winning opening 37. More specifically, the special symbol display device 17 specially displays the lottery result. The display is performed in such a manner that the pattern (number or pattern) is changed and then stopped. This special symbol display device 17 uses a 7-segment display in this embodiment, and is separated from the lower right portion of the game board 3 so as not to enter the field of view of the player who is watching the effect display device 34 at the same time. Is provided.

  In this embodiment, the special symbols are described using numbers from 1 to 9, as will be described later, but the actual display on the special symbols display device 17 corresponds to the numbers from 1 to 9. Symbols are used. This is to prevent the player from easily distinguishing the types of special symbols.

  The stage 36 is disposed below the effect display device 34, and is a structure where the game ball stays temporarily while rolling. A groove is formed at the center of the stage 36, and a start winning opening 37 is disposed at a position directly below the groove. Therefore, the game ball dropped from the groove is guided to the start winning opening 37 with a high probability. The attacker device 41 is a device that is opened a predetermined number of times when the game is won as a result of an electronic lottery when the game ball is won at the start winning opening 37 and the game is changed to a jackpot game or a sudden probability change game. . When the attacker device 41 is opened, the big winning opening 42 is exposed, and a lot of prize balls can be obtained by winning game balls there. In addition, when a game ball wins the general winning opening 38, a predetermined number of game balls are paid out to the player as prize balls. The game balls that have not entered the start winning opening 37 or the general winning opening 38 are collected from the out opening 39. It should be noted that sensors 43 to 45 (see FIG. 4) for detecting the passage of game balls are provided inside the start winning port 37, the general winning port 38, and the big winning port 42, respectively.

  The front board 6 is provided with a receiving tray 5 that accommodates game balls and can be discharged to the outside. This tray 5 can accommodate not only game balls thrown by the player but also game balls paid out as prize balls from the prize ball payout device 14. A launching device 9 for launching game balls toward the game area 31 is attached to the lower part of the front frame 2, and the game balls accommodated in the tray 5 are supplied to the launching device 9 one by one. The Then, when the handle 7 attached to the lower right of the front board 6 is rotated, the launching device 9 can launch the game ball to the game area 31 with a launch intensity corresponding to the turning amount. Yes.

  The main control processing unit 11 is provided on the back surface of the game board 3 via a support member or the like. The main control device 11 performs CPU (Central Processing Unit) 11a, ROM (Read Only Memory) 11b for storing a predetermined control program, temporary storage of generated processing information, and deletion of stored information. It is composed of a RAM (Random Access Memory) 11c and the like, and performs main processing related to games.

  Specifically, as shown in FIG. 4, an electronic lottery unit (electronic lottery means) 111 that performs electronic lottery when a game ball is won in the start winning opening 37, and the lottery result of the electronic lottery unit 111 is A lottery result determination unit 112 that determines whether the winning or failure is made, and a special symbol determination unit (special symbol determination unit) that performs symbol lottery determination to determine a special symbol according to the lottery result determined by the lottery result determination unit 112 Symbol determining means) 113 and symbol variation pattern determination for determining a display pattern (symbol variation pattern) for causing the special symbol display device 17 to stop the special symbol determined by the special symbol determining unit 113 after the special symbol is varied When the determination of the lottery result by the unit 114 and the lottery result determination unit 112 is successful, the attacker device 41 (solenoid thereof) is operated to make a big hit game or suddenly change the probability. Special game transition control unit (game control means) 115 that shifts to a game and processing pattern of game processing that is performed during the transition to a game per sudden probability change when the lottery result by the lottery result determination unit 112 suddenly becomes a chance change The main control processing unit 11 includes a processing pattern selection unit (processing pattern selection unit) 116 for selecting (including pre-processing, operation processing of the attacker device 41, and post-processing, which will be described in detail later).

  Here, the electronic lottery unit 111 includes a random number generation unit and a random number acquisition unit (not shown). When the start winning port detection sensor 43 detects a winning of a game ball, the random number acquisition unit is a random number generation unit. Get one random number generated in. Then, the lottery result determination unit 112 determines whether the acquired random number corresponds to a win or a loss. If the random number is a win, the lottery result determination unit 112 further determines whether the win is “big hit” or “suddenly” It is determined whether it is “probable hit” (determined by lottery).

  Next, the processing pattern selected by the processing pattern selection unit 116 will be described with reference to FIG. First, the processing pattern is composed of three processes: a pre-process, an attacker device operation process, and a post-process, and a plurality of process patterns are mainly corresponding to the types of special symbols determined by the symbol lottery determination. It is stored in the ROM 11b of the control processing unit 11. The plurality of processing patterns will be described in detail. First, when the special symbol is “2, 4, 6, 8”, the waiting time (preprocessing) until the attacker device 41 is opened is continued for 10 seconds. A processing pattern A of 57 seconds in total is selected, in which the processing of the opening / closing operation of the attacker device 41 is 7 seconds and the waiting time (post-processing) until the attacker device 41 closes and shifts to the next game is 40 seconds. ing. Similarly, when the special symbol is “1, 5, 9”, the processing pattern B of 57 seconds in total, which is 20 seconds for the preprocessing, 7 seconds for the operation processing of the attacker device, and 30 seconds for the postprocessing, is selected. When the special symbol is “3, 7”, the processing pattern C of 57 seconds in total, which is 30 seconds for the pre-processing, 7 seconds for the operation processing of the attacker device, and 20 seconds for the post-processing, is selected. It can be said that the special symbol determination unit is a means for lottery determination of the operation start timing of the attacker device during execution of the second half common effect mode (total 57 seconds).

  As is clear from FIG. 5, these processing patterns are the same as the processing time of 7 seconds for the attack device 41 to open and close, and the total processing time is also 57 seconds. Processing time and post-processing time are different. That is, the timing (T3, T4, T5) at which the attacker device 41 starts to open differs depending on the special symbol.

  Next, a 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 is determined by the lottery result (big hit, sudden chance change, lose) determined by the lottery result determination unit 112 from the main control processing unit 11 and the symbol variation pattern determination unit 114. In response to the special pattern variation pattern commands, based on these commands, the production mode selection unit (production mode selection means) 121 selects a predetermined production mode from a plurality of types of production modes stored in the ROM. select. The effect display control unit 12a controls the effect display device 34 to display the selected effect mode. Here, the plurality of types of effect modes stored include a common effect mode (see FIG. 5) described later.

  The special symbol display control unit 12b receives a special symbol 113 command determined by the special symbol determination unit 113 of the main control processing unit 11 and a special symbol variation pattern command determined by the symbol variation pattern determination unit 114. The special symbol determined by the special symbol determining unit 113 is displayed on the symbol display device 17 in such a manner that the special symbol is changed and then stopped.

  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.

  Further, the payout control processing unit 12e receives the payout command from the main control processing unit 11 in addition to controlling the prize ball payout device 14 so as to rent a game ball to the player in response to a signal from the CR unit. The prize ball payout device 14 is controlled so as to pay the number of prize balls 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 12d, and a launch stop signal is received when the CR unit is not connected.

  Next, as a result of playing the pachinko machine P configured as described above, the transition of the gaming state when the player suddenly hits the probability change will be described with reference to the timing chart shown in FIG.

"Control performed between T1 and T2"
The electronic lottery unit 111 performs electronic lottery when a game ball wins the start winning opening 37. The lottery result determination unit 112 determines the random number extracted by the electronic lottery unit 111 with reference to a lottery table (not shown) for winning / losing. Here, in order to describe a case where the odd win is sudden, the lottery result determination unit 112 determines that it is a sudden win. Furthermore, the special symbol determination unit 113 determines a special symbol (“2” in the present embodiment) to be stopped and displayed on the special symbol display device 17 from a plurality of special symbols. In addition, the symbol variation pattern determination unit 114 determines the time from when the special symbol varies until it stops (in this embodiment, a pattern of 3 seconds). Further, the processing pattern selection unit 116 selects the pattern A that is the operation processing pattern of the attacker device 41 corresponding to the special symbol (“2” in the present embodiment) determined by the special symbol determination unit 113.

  Further, upon receiving a determination command from the symbol variation pattern determination unit 114 (a command indicating that the pattern is a 3 second pattern in this embodiment), the special symbol display control unit 12b changes the special symbol to the special symbol display device 17. Display. And the production | presentation aspect selection part 121 of the production | presentation display control part 12a selects the common production | presentation aspect selected even if it is a sudden winning change, a big hit, or a loss. This common production mode is composed of a first half common production mode and a second half common production mode, and is preset so that the production time of the first half common production mode is the same as the special symbol variation time of 3 seconds. Has been. The processing so far is processing performed at the timing of T1. Then, the special symbol display control unit 12b causes the special symbol display device 17 to variably display the special symbols until the time from T1 to T2 (first time: 3 seconds) elapses.

  At the timing of T2, the special symbol being variably displayed on the special symbol display device 17 is stopped, and the special symbol (“2” in the present embodiment) is determined. Since the determined special symbol is a special symbol determined based on the sudden probability variation, the special game transition control unit 114 subsequently shifts to the sudden probability variation game. As described above, the special symbol display device 17 displays the symbol corresponding to the special symbol “2”, and it is not easy for the player to know that the special symbol is “2”.

  In addition, at the timing T2, the effect display control unit 12a ends the effect of 3 seconds in the first half common effect mode, and generates a command (fanfare command) that triggers execution of the next effect. That is, the fanfare command is generated at the timing of T2 when the first time has elapsed since the display of the first half common effect mode on the effect display device 34 was started. In response to the fanfare command, the second half common effect mode selection unit (second half common effect mode selection means) 122 selects the second half common effect mode from the common effect modes and displays it on the effect display device 34. In addition, as the first half common performance mode, the contents are a so-called reach state or a chance eye display at the timing of T2.

  Specifically, at the timing of T2, one dummy symbol is changing, and the remaining dummy symbols are of the same type and change is stopped (7 to the left and inside of the effect display device, respectively). The symbol is stopped and the right symbol is changing), or all dummy symbols are temporarily stopped in a specific manner at the timing of T2 (left, middle, right The state in which the symbols 3, 5, and 7 are stopped in order is displayed. The processing so far is performed at the timing of T2.

“Processes performed between T2 and T9”
In the time period from T2 to T9, the effect display device 34 performs the effect in the latter half common effect mode for 57 seconds which is the second time. During this time, the attacker device 41 opens and closes. However, in this embodiment, “2” is determined as the special symbol, and the processing pattern A is selected based on this determination. The attacker device 41 does not open and close until the timing of T3 when 10 seconds elapse. That is, the preprocessing time is 10 seconds. Then, at the timing of T3, the attacker device 41 opens and closes twice for 7 seconds (one open time is 0.4 seconds). And the attacker apparatus 41 maintains a closed state at the timing of T6, and a post-process is complete | finished at the timing of T9 when 40 second passed from there. At the timing of T9, the production in the latter half common production mode is performed for 57 seconds and is finished. In other words, the timing of the end of the suddenly odd game is synchronized with the end timing of the second half common effect mode.

  In addition, when the special symbol is “1, 5, 9”, the processing pattern B is selected, so the preprocessing is 20 seconds between T2 and T4, and the operation process of the attacker device is T4. Post-processing is performed for 30 seconds from T7 to T9 for 7 seconds between. In addition, when the other symbol is “3, 7”, the processing pattern C is selected, so that the preprocessing is 30 seconds between T2 and T4, the attacker device operation processing is 7 seconds between T4 and T7, Post-processing is performed for 20 seconds from T7 to T9.

  Then, when the process in the game is suddenly changed, the game shifts to the probability variation game. That is, when a game ball wins the start winning opening 37 after the timing of T9, the game is played in a gaming state with a high probability of winning in the electronic lottery.

  As described above, according to the pachinko machine P according to the present embodiment, even if a game ball wins the start winning opening 37 and suddenly hits the odds, the common effect mode displayed on the effect display device 34. In addition to being able to open and close the attacker device 41 without noticing, since the opening and closing timing (operation time) of the attacker device 41 varies depending on the special design, it is predicted when the attacker device 41 will open and close. Have difficulty. Moreover, it is rare to play while only the attacker device 41 is concerned. Therefore, the possibility of noticing the opening / closing of the attacker device is very low even if it is a sudden probability change. In addition, since the reach state and the chance eyes are displayed when the first time has elapsed (time point T2), the player's eyes are further nailed to the effect display device, and suddenly the game is shifted to the probable winning game. There is little possibility of noticing.

  Further, since the latter half common effect mode is controlled based on the fanfare command, there is also an advantage that the timing of display control of the effect can be easily synchronized. Furthermore, when the game is suddenly changed to a probability change game, the game is shifted to a probability variation game. However, the processing time after the end of the effect displayed on the effect display device 34 and the game is suddenly changed to a probability change game is the same second time. Therefore, the timing of the end of the production and the transition to the probability variation game also coincide. For this reason, there is no sense of incongruity that the probability variation game starts in the middle of the performance.

  In addition, in a probability variation game after a sudden chance change game, if the effect displayed on the effect display device is unique to the probability variation game, it will be interesting to the player. For example, in a game after the transition to the probability variation game, for each game, an effect such as “Possibility of transition to the probability variation game within another game ??%” is displayed on the effect display device, and the number of games is displayed. Every time? ? If the performance is such that% is close to 100%, it is possible to give the player a sense of expectation that the game may shift to a probability variation game. Here, “1 game” means that a game ball wins a start winning opening and electronic lottery is performed, and a special symbol is variably displayed based on the lottery result. The processing operation until the special symbol stop display is confirmed.

  In the present embodiment, when the common effect mode is selected instead of the sudden probability change, and the common effect mode is selected, the special symbol changes at the timing of T9 when the effect of the common effect mode ends. After stopping, it shifts to the jackpot game and the attacker device 41 opens and closes, but since this is known per se, its description is omitted.
