Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a ball game machine capable of extending a game stop time and improving an operation rate.

  Ball game machines that perform special symbol lottery and normal symbol lottery are known. The special symbol lottery is performed according to the winning of the game ball with respect to the start opening, and the special electric accessory (large winning opening) is controlled to open according to the lottery result. In addition, the normal symbol lottery is performed in accordance with the winning of a game ball at a specific winning opening or the passing of the game ball at a specific gate, and according to the lottery result, it is easy to win a normal electric accessory (starting port winning). Is controlled to open.

  Normally, in this type of ball game machine, by changing the lottery conditions for special symbol lottery (winning probability, etc.), lottery conditions for normal symbol lottery (lottery cycle, winning probability, etc.) Various game modes appear. Hereinafter, transition of a general game mode will be described with reference to FIG.

(1) Normal mode In this game mode, a low probability (for example, 1/300) is applied among the two stages of jackpot probabilities in the special symbol lottery. Moreover, in this game mode, the lottery cycle of the normal symbol lottery is long, and the opening time of the ordinary electric accessory is also short.

(2) Big hit mode This game mode is executed when a special symbol lottery is won and the special symbol stops in a predetermined big hit arrangement, and the special electric accessory is released. This release operation is repeated over a predetermined number of rounds (for example, 15 rounds), for example, with the passage of a predetermined time (for example, 30 seconds) or a predetermined number of winnings (for example, 10 balls) as one round.

(3) Probability variation mode This game mode is executed with a predetermined probability (for example, 1/2) after the jackpot mode ends. In this game mode, not only a high probability (for example, 1/30) of the two-stage jackpot probabilities in the special symbol lottery is applied, but also the variation time of the special symbol is shorter than in the normal mode. In the probability variation mode, since the lottery cycle of the normal symbol lottery is short and the opening time of the ordinary electric utility is long, the big hit can be generated again with almost no reduction in the number of possessions.

(4) Time reduction mode This game mode is executed after the big hit mode (per non-stochastic fluctuation) is completed. In this game mode, the jackpot probability of the special symbol lottery is low, but the variation time of the special symbol is shorter than the normal mode, as in the probability variation mode. In addition, since the lottery cycle of the normal symbol lottery is short and the release time of the ordinary electric utility is long, the game can be continued with almost no reduction in the number of possessions. However, this mode is terminated when the special symbol lottery number reaches a predetermined number N1 (for example, 100 times) after the big hit, and the mode is switched to the normal mode.

Also, in this type of ball game machine, various effect modes appear depending on the difference in liquid crystal screen display and effect sound. Usually, the period of the production mode coincides with the period of the game mode, but there is also a ball game machine that activates a specific production mode (for example, mission mode) during the normal mode and produces an effect different from the normal mode. It is known (see, for example, Patent Document 1).
JP 2005-31670 A

  However, in the conventional ball game machine, when the time shortening mode ends, the transition to the normal mode is performed simultaneously with the transition to the normal mode, so the chance period (a period advantageous to the player) has ended. There is a problem that the game is hard to receive when you stop playing.

  Moreover, like the bullet ball game machine described in Patent Document 1, when the specific effect mode is executed during the normal mode, it is possible to suppress the end of the game during the specific effect mode and improve the availability factor. However, since the specific effect mode executed during the normal mode is a pure effect that does not affect the appearance, if the player notices it, there is a problem that the interest in the specific game mode disappears.

[Direction mode]
Next, the production mode of the pachinko gaming machine 1 will be described with reference to FIGS. The peripheral board 25 causes various effect modes to appear depending on the difference in liquid crystal screen display and effect sound. The period of each production mode is normally coincident with the period of the game mode. For example, the normal production mode activated in the normal mode, the big hit production mode activated in the big hit mode, and the probability fluctuation activated in the probability variation mode. The effect mode, the time reduction effect mode activated in the time reduction mode, and the like are prepared. In the pachinko gaming machine 1 according to the embodiment of the present invention, a specific effect mode appears across two game modes. For example, the specific performance mode of the present embodiment is executed over the time reduction mode and the normal mode, but may be executed over the probability variation mode and the normal mode with a limited number of times (for example, 100 times). In addition, the specific performance mode of the present embodiment is activated after the end of the big hit mode (per non-stochastic fluctuation), but triggered by the start of the time reduction mode or the probability fluctuation mode (with a limited number of times) that appears suddenly during the normal mode. You may start as

  More specifically, the peripheral board 25 activates a specific effect mode that continues for a predetermined number of special symbol lotteries (N1 + N2), triggered by the start of the time reduction mode, and continues during the specific effect mode. Perform a certain production. For example, if the limit number N1 of the time reduction mode is 100 times and the subsequent effect continuation number N2 is 100 times, continuous effects are performed over 200 special symbol lotteries. On the other hand, the main circuit board 24 makes the lottery conditions for the normal symbol lottery and the opening time of the ordinary electric accessory 14a advantageous to the player for the predetermined number of special symbol lottery times (N1) from the start of the specific effect mode. Make a shortened mode appear. In addition, after the time reduction mode is finished, the normal symbol lottery conditions and the opening time of the ordinary electric accessory 14a are set to the normal state over the predetermined special symbol lottery number (N2) even in the specific effect mode. To. Needless to say, when a big hit occurs during the specific effect mode, the specific effect mode is terminated regardless of the number of times N1 and N2, and the mode is changed to the big hit mode (big hit effect mode).

  In this way, even if the time reduction mode advantageous to the player ends and the normal mode is entered, the specific effect mode is continuously performed, so the sense that the chance period has ended can be eased. it can. Thereby, the stop time of a game can be extended and an operation rate can be improved. Moreover, since the specific effect mode is executed across the time reduction mode and the normal mode that are advantageous to the player, the player's interest can be sustained as compared with the conventional specific effect mode that does not affect the appearance.

  As shown in FIGS. 8 and 9, the peripheral board 25 of the present embodiment continuously displays the liquid crystal background image H and the lottery pattern Z having a pattern different from that in the normal mode over the entire period (N1 + N2) of the specific effect mode. Used for. Further, during the specific effect mode, it is preferable to continuously use effect sounds having a pattern different from that in the normal mode. In this way, even if the game mode advantageous to the player ends, the continuity of the specific effect mode is appealed by the liquid crystal background image H or the like, and the sense that the chance period has ended can be eased.

Further, as shown in FIG. 7, the peripheral board 25 of the present embodiment increases the appearance rate of the specific notice effect over the entire period (N1 + N2) of the specific effect mode or the rear period (N2) of the specific effect mode. . That is, as is clear from FIG. 7, the specific performance mode is divided into a front period (N1) and a rear period (N2), and after the entire period (N1 + N2) is executed, the normal performance mode is activated. However, the appearance rate (10%) of the specific notice effect in the rear period (N2) is that of the front period (N1) of the specific effect mode set higher than the appearance rate (2%) in the normal effect mode. It is set to be higher than the appearance rate (5%). If it does in this way, due to the expectation for the big hit, it is possible to extend the game stop time until the specific performance mode is ended.

  Further, as shown in FIG. 7, the peripheral board 25 of the present embodiment performs a story-like effect over the entire period (N1 + N2) of the specific effect mode or the rear period (N2) of the specific effect mode. The end of the story is shown at the end of the specific performance mode. For example, when the time reduction mode ends, a murder case is generated on the liquid crystal screen (step 1). After that, depending on the number of lotteries, the story is developed such as the appearance of a detective, the investigation of suspect A, the investigation of suspect B, etc. (step 2 to step 8), and the detective contradicts at the end of the specific production mode. Find the point and identify the criminal (step 9). In this way, due to the interest in the end of the story, it is possible to extend the game stop time until the specific performance mode ends. The story effect (1) shown in FIG. 7 shows an example of the story effect executed over the rear period (N2) of the specific effect mode, and the story effect (2) is the entire period (N1 + N2) of the specific effect mode. ) Is an example of a story effect executed over the entire period.

  Next, a control procedure for realizing the specific effect mode as described above will be described with reference to FIGS. 10 and 11. As shown in FIG. 10, in the effect mode switching process, it is determined whether or not the game mode is a jackpot mode (S10). If the determination result is YES, the jackpot effect mode is executed (S11). If the determination result in S10 is NO, it is determined whether or not the game mode is the probability variation mode (S12). If the determination result is YES, the probability variation effect mode is executed (S13). If the determination result in S12 is NO, it is determined whether or not the game mode is the time reduction mode (S14). If the determination result is YES, the specific effect mode is executed (S15). If the determination result in S14 is NO, the number of special symbol lotteries after the end of the time reduction mode is determined (S16), and if this is N2 (for example, 100 times) or less, the specific game mode is executed ( S15). If the determination result in S16 exceeds N2 (100 times), the normal performance mode is executed (S17).

  As shown in FIG. 11, in the specific effect mode process, first, it is determined whether or not the game mode is the time reduction mode (S20). If the determination result is YES, the notice effect process for the specific effect mode is performed. (S21), liquid crystal background processing (S22), lottery symbol processing (S23), effect sound output processing (S24), and the like are performed. On the other hand, when the game mode is the normal mode, the notice effect process (S25), the liquid crystal background process (S22), the lottery symbol process (S23), the effect sound output process (S24), etc. The appearance rate of the effect process (S25) is different. When the game mode is the normal mode, the above-described story effect process (S26) is also executed.

  According to the present embodiment configured as described, the main board 24 includes a main board (game control unit) 24 that performs control related to the game, and a peripheral board (production control unit) 25 that performs control related to the effect. Performs a special symbol lottery according to the winning of the game ball to the starting port 14, controls the opening of the special electric accessory 15a according to the lottery result of the special symbol lottery, and according to the passing of the game ball at the gate 17 In the pachinko gaming machine 1 that performs the normal symbol lottery and controls the opening of the ordinary electric accessory 14a according to the lottery result of the normal symbol lottery, the peripheral board 25 continues for a predetermined number of special symbol lotteries (N1 + N2). A specific production mode is activated, and a continuous production is performed during the specific production mode. The main board 24 has a predetermined number of special symbol lottery times (N1) from the start of the specific production mode. The lottery conditions for the symbol lottery and the opening time of the ordinary electric accessory 14a are set to be advantageous to the player. Thereafter, the lottery conditions for the normal symbol lottery and the ordinary electric accessory 14a are changed over a predetermined number of special symbol lottery times (N2). Since the opening time is set to the normal state, the game mode (time reduction mode) advantageous to the player ends, and even if the mode is shifted to the normal mode, the performance in the specific effect mode is continuously performed and the chance period ends. The feeling of having done is relieved. Thereby, the stop time of a game can be extended and an operation rate can be improved. In addition, since the specific effect mode is executed over the game mode and the normal mode advantageous to the player, the player's interest can be sustained as compared with the conventional specific effect mode that does not affect the appearance.

  Further, since the peripheral board 25 continuously uses the liquid crystal background image H, the lottery symbol Z, and the effect sound of the same pattern for the entire period (N1 + N2) of the specific effect mode, the game mode advantageous to the player is ended. Even so, it is possible to appeal the continuity of the specific effect mode with the liquid crystal background image H or the like, and relieve the sense that the chance period has ended.

  Further, the peripheral board 25 increases the appearance rate of the notice effect by the movable accessory 23 over the entire period (N1 + N2) of the specific effect mode or the rear period (N2) of the specific effect mode. The game can be stopped until the specific performance mode is finished.

  Further, the peripheral board 25 performs a story-like effect over the entire period (N1 + N2) of the specific effect mode or the rear period (N2) of the specific effect mode, and indicates the end of the story at the end of the specific effect mode. Therefore, due to interest in the end of the story, the game stop time can be extended until the specific performance mode ends.
