Abstract

<P>PROBLEM TO BE SOLVED: To provide a pinball game machine which can simplify the control concerning the mode transition. <P>SOLUTION: When a Pachinko game ball 7 enters into a start winning opening 10 while the first special direction mode is on, a mode random number value is acquired after a lottery at the winning lottery section 31d. A mode transition determination section 42 determines if the mode changes over or the mode continues on. When the mode continuation is determined, a direction random number value acquisition section 43 acquires the random number value for direction. The direction random number value acquisition section 43 sends the acquired direction random number value to a direction lottery section 44. When the mode transition is judged, a mode random number value acquisition section 41 decides to use the acquired random number value as the direction random number value and sends it to the direction lottery section 44. The direction lottery section 44 compares the random number value which has been sent and the direction lottery table 47, draws by the lottery the direction data, and then draws by the lottery the direction data for the mode which performs the direction from among the direction data thus chosen by the lottery. A sub CPU 32a performs the direction by controlling LCD9 from the direction data chosen by the lottery. <P>COPYRIGHT: (C)2010,JPO&INPIT

  In conventional pachinko machines including Patent Documents 1 to 3, when changing the mode, it is necessary to perform an effect corresponding to the mode at the transfer destination. When performing the mode change control, first, a random number for mode change lottery is acquired. Then, the lottery of whether or not to shift to the mode is performed based on the mode random number value. Then, after performing the mode transition lottery, a random number value for the effect is acquired, and based on this effect random number value, the effect corresponding to the mode in which the effect is performed is selected. For this reason, it is necessary to perform two random number value acquisition processes and two lottery processes in each game, and there is a problem that control related to mode transition becomes complicated.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a ball game machine capable of simplifying control related to mode transition.

  In order to achieve the above object, the ball game machine of the present invention is played in a plurality of modes each having a plurality of performance data with different performances, and a plurality of hits are triggered by winning at a winning opening. Mode in which any one of a plurality of random numbers for mode transition determination is obtained by lottery after lottery by the winning lottery means in a ball game machine that draws one of the game and the lose by the lottery means Based on the determination result of the random number value acquisition means, the mode transition determination means for determining whether or not to shift the mode based on the mode random value acquired by the mode random value acquisition means, and the determination result of the mode transition determination means When the mode control means for changing the mode and the mode change determining means determines that the mode is not changed and the mode is continued, any one of a plurality of random numbers for effect lottery is selected by lottery. The same randomness that determines that the mode random number value acquired by the mode random value acquisition means is used as the effect random value when it is determined that the mode change is determined by the acquired effect random value acquisition means and the mode change determination means. When shifting to the mode with the numerical value determining means, based on the effect random number value determined by the same random number value determining means, lottery one of the plurality of effect data corresponding to the mode of the transfer destination, When the mode is continued, based on the effect random value acquired by the effect random number acquisition means, the effect lottery means for drawing one of the plurality of effect data corresponding to the mode to be continued, and the effect And an effect control means for effecting the effects drawn by the lottery means.

  Further, the plurality of modes are shifted to a normal effect mode and a first special for performing an effect different from the normal effect mode, when the specific winning of the plurality of hits is drawn by the winning lottery means. The mode random number acquisition means acquires the mode random number value in the first special effect mode, and the mode transition determination means starts from the first special effect mode to the normal effect mode. It is preferable to determine whether or not to shift to the above.

  Further, the plurality of effect modes have a second special effect mode for performing effects different from the normal effect mode and the first special effect mode, and the mode random number acquisition means is also in the second special effect mode. The mode random number value is acquired, and the mode transition determining means also determines whether or not to transition from the first special effect mode to the second special effect mode in the first special effect mode, and to determine the second special effect mode. In the effect mode, it is preferable to determine whether or not to shift from the second special effect mode to the normal effect mode.

  In addition, the specific winning is per normal probability, and the probability of the plurality of winnings being drawn by the winning lottery means is the normal probability until one of the plurality of winnings is drawn next. When the lottery means is selected by the winning lottery means to shift to the first special effect mode, the second mode is determined by the mode transition determining means. It is preferable that the probability determined to shift to the special effect mode is higher than when the normal probability per lot is selected by the winning lottery means and the first special effect mode is entered.

  According to the ball game machine of the present invention, when it is determined that the mode is to be changed, it is determined to use the mode random value acquired by the mode random value acquisition unit as the effect random value, and the determined effect random value Based on this, since one piece of effect data is drawn, in this case, the effect random value acquisition means is not operated. Thereby, compared with what operates every game and effect random number value acquisition means, the control which concerns on mode transfer can be simplified.

  As shown in FIG. 1, a pachinko machine 2, which is an embodiment of a gaming machine and is called a digital pachinko machine, has a game board 4 disposed inside a main body frame 3, and a front side of the main body frame 3. The front door 5 is assembled so that it can be opened and closed. Below the front door 5, an operation handle 8 for adjusting the launch strength of the supply tray 6 for supplying the hit ball and the pachinko ball 7 is provided. At the approximate center of the game area 4a where the pachinko ball 7 of the game board 4 is launched, various symbols are displayed on the liquid crystal screen during the game based on predetermined winning conditions such as winning the pachinko ball 7 in a predetermined winning opening. There is provided a symbol variable display device (hereinafter referred to as LCD) 9 that displays a change after a variable display within a predetermined time.

  Around the LCD 9, a start winning port 10, a normal winning port 11, an attacker 12, and an out port 13 are provided.

  A winning ball detection sensor 15 (see FIG. 2) for detecting the pachinko ball 7 that has entered the winning ports 10, 11 is provided in each of the winning ports 10, 11. The player inserts the pachinko ball 7 into the supply tray 6 and guides the pachinko ball 7 to the ball launching device 16 (see FIG. 2) through a guide path provided in the supply tray 6 to perform a rotary operation. The pachinko ball 7 is launched toward the upper side of the game area 4a of the game board 4 by rotating the handle 8 by a predetermined amount to control the driving of the ball launching device 16. The hit pachinko ball 7 enters one of the winning ports 10, 11 or the attacker 12 or is collected from the out port 13 while flowing down from above the game area 4a.

  A big prize opening 17 is provided in the back of the attacker 12, and a big prize ball detection sensor 18 (see FIG. 2) for detecting the pachinko ball 7 that has entered the big prize opening 17 is provided in the big prize opening 17. It has been. The attacker 12 is attached so as to be rotatable between an open position for opening the big prize opening 17 and a closed position for closing the big prize opening 17. Note that a plurality of structures such as nails and windmills provided in the game area 4a of the pachinko machine 2 are well-known and will not be described.

  The front door 5 is assembled to the front surface of the main body frame 3 so as to be freely opened and closed. Visible glass is attached to the inside of the front door 5. Two speakers 21 are provided on the front door 5. A touch button 22 is provided above the operation handle 8.

  When the pachinko ball 7 wins the start winning opening 10, on the LCD 9, for example, the variable display of the three rows of the symbols 23 including the numbers 0 to 9 is started, and the symbols 23 scroll from the top to the bottom. The symbol variation display is performed by selecting one of a plurality of variation patterns. The variably displayed symbols 23 are stopped one by one in sequence (in order from left to right to middle), and the winning lottery results are displayed.

  A holding ball display unit 24 is provided on the right side of the LCD 9. When the pachinko ball 7 wins the start winning opening 10 while the pattern 23 is displayed on the LCD 9 in a variably displayed state, the hold ball that is put on hold in the control based on the winning is limited to a predetermined number (for example, four times). And the number of reserved balls is displayed by the reserved ball display unit 24. When the holding ball is displayed by the holding ball display unit 24 at the time when the display is stopped after the symbol 23 is variably displayed on the LCD 9, one holding ball display is turned off and the holding state is released, and then again. Variation display of the symbol 23 is started on the LCD 9.

  As shown in FIG. 2, the operation of the pachinko machine 2 is basically controlled by the main control board 31 and the sub control board 32. The main control board 31 and the sub control board 32 are each provided with a connection terminal, and the main control board 31 and the sub control board 32 are electrically connected by connecting the connection terminals with a connection cable or the like.

  The main control board 31 includes a main CPU (central processing unit) 31a, a main ROM (read only memory) 31b, a main RAM (random access memory) 31c, and a winning lottery unit 31d. The main CPU 31a reads a game control program stored in the main ROM 31b in accordance with an input signal input from the winning ball detection sensor 15, generates a command for controlling the gaming state of the pachinko machine, and also generates a sub-control board 32. The command information is transmitted to and executed in a predetermined gaming state. The main RAM 31c is a working area and is used for temporary storage or rewriting of data used in the game.

  When the signal from the winning ball detection sensor 15 is input, the main CPU 31a drives the ball payout device 27 based on the game control program stored in the main ROM 31b to supply a predetermined number of pachinko balls 7 Pay up. It should be noted that the number of pachinko balls 7 to be paid out may be appropriately set according to the types of the winning ports 10 and 11 where the pachinko balls 7 have won. The ball launcher 16 is connected to the main CPU 31a, and the driving is controlled by the main CPU 31a.

  When the pachinko ball 7 entering the start winning opening 10 is detected by the winning ball detection sensor 15, a start signal is input to the main CPU 31a. The main CPU 31a operates the winning lottery unit 31d in response to the input of the start signal.

  The winning lottery unit 31d includes a random number generator, a random number sampling circuit, and a winning determination table, and draws one random number value every time a winning of the pachinko ball 7 is detected by the winning ball detection sensor 15 of the start winning opening 10. To do. The random number value selected by lottery is checked against a hit determination table, whether or not to shift to the probability variation mode or the first special effect mode is determined as a result of the lottery determination, and information (for example, command) related to the determination is generated.

  In the hit determination table, random numbers are grouped into six groups according to their sizes. The six random number groups are lost, “5R probability variation per game” that increases the chance of winning until the next time is drawn, and “16R probability variation” that increases the probability of winning until the next time is drawn. “2R Probability Per Change”, “2R Normal Per Change”, and “Small Win” are assigned to each group, and the sampled random values are the values that belong to any group. Depending on whether or not there is a win determination that determines whether to win or not. When the lottery is completed, a lottery result signal is fed back to the main CPU 31a. The main CPU 31a sends, as a lottery result signal, any one of a loss signal, a 5R probability variation signal, a 16R probability variation signal, a 2R probability variation signal, a 2R normal variation signal, and a small hit signal to the sub CPU 32a.

  When the winning lottery unit 31d selects “5R probability variation per unit” or “16R probability variation per unit”, the main CPU 31a rotates the attacker 12 to the open position, and the attacker 12 is released for 30 seconds, or a big prize opening In the case of “5R probability variation”, it is assumed that 10 pachinko balls 7 are won in 17 (10 pachinko balls 7 are detected by the large winning ball detection sensor 18). In the case of “winning”, 16 rounds are continuously executed. When “5R Probable Per Change” or “16R Probable Per Change” is drawn, the probable change per decision table has a higher probability of hitting than the normal time until the next hit (excluding “Small Win”) is drawn. The process shifts to a probability changing mode used at the time of lottery in the section 31d.

  The main CPU 31a, when the winning lottery unit 31d draws “2R probability variable hit”, “2R normal hit”, and “small hit”, the attacker 12 is rotated to the open position, and the attacker 12 is released for 0.5 seconds. 2 rounds are continuously executed (game is played per 2 rounds). Then, after the game is played per two rounds, the process proceeds to the first special effect mode in which an effect different from the normal effect mode is performed. In addition, when “2R probability variation win” is selected and the process shifts to the first special effect mode, the probability variation determination table is used at the time of lottery in the winning lottery unit 31d until the next winning is selected. The pachinko machine 2 is provided with a second special effect mode for performing an effect different from the normal effect mode and the first special effect mode. In the first special effect mode, is the transition to the normal effect mode or the second special effect mode? Whether to continue the first special effect mode is determined.

  The sub control board 32 includes a sub CPU 32a, a sub ROM 32b, and a sub RAM 32c. The sub CPU 32a appropriately reads out the control program for the sub control device stored in the sub ROM 32b, and performs drive control of the LCD 9 in accordance with the control program for sub control according to the control signal input as command information from the main control board 31. . The sub RAM 32c serves as a working area, and is used for temporary storage or rewriting of data used in the control of the LCD 9.

  The sub ROM 32b stores graphic data of each symbol 23, a random symbol sampling circuit for stop symbols, a stop symbol table, and an effect control program for each mode. When the lottery result signal is input, the sub CPU 32a performs random number sampling based on the stop symbol random number sampling circuit stored in the sub ROM 32b, and compares the sampled random number value with the stop symbol table, A combination of symbols 23 to be stopped on the winning active line is determined. The sub CPU 32a controls the variable display and stop display of the symbol 23 on the LCD 9 based on the determined symbol combination.

  In the first special effect mode and the second special effect mode, the player is notified whether “2R probable per win” has been drawn and shifted, or “2R normal hit” or “small hit” has been drawn and transferred. It is a probabilistic latent production that suggests the possibility of a probable state. In each special effect mode, every time the pachinko ball 7 wins in the start winning opening 10, the effect control program for each special effect mode stored in the sub ROM 32b is read and used as an effect as a point addition effect game (hereinafter referred to as an effect game). Is executed on the LCD 9.

  In the effect game, when the player depresses the touch button 22, the player acquires points, and the total points obtained by accumulating the points already acquired by the player are displayed on the LCD 9. In the effect game, the total points are allowed to reach a target point (for example, 10,000 points) only when “5R probability variation” or “16R probability variation” is selected by the winning lottery unit 31d. Thereby, since it seems to the player that “5R probability variation” or “16R probability variation” is determined when the total points reach the target point, the player can be actively involved in the production game. .

  As shown in FIG. 3, in the effect game in the first special effect mode, by depressing the touch button 22, two enemy characters (hereinafter simply referred to as enemies) E <b> 1 and E <b> 2 displayed on the screen are defeated. Earn points. In the first special effect mode, the game screen is displayed on the LCD 9 together with the symbol 23, and the background on the game screen is daytime. The game screen includes, for example, a central area 35a where the enemies E1 and E2 are displayed, a target point display area 35b where the target points are displayed, and a total point display area 35c where the total points the player has acquired so far are displayed. And a message area 35d where a button pressing operation instruction to the player and various messages are displayed.

  When the enemies E1 and E2 are displayed in the central area 35a, a button press operation instruction such as “press touch button” is given to the message area 35d to defeat the enemy E1 first. If the player presses the touch button 22 within a predetermined time after the pressing operation instruction is given, an effect of defeating the enemy 1 is executed on the screen, and the points determined in advance by lottery are added to the total points. Is done. If the player does not press the touch button 22 even after a predetermined time has elapsed, an effect that the player is defeated is executed, and points are not added. Next, a pressing operation instruction for defeating the enemy 2 is made. Similarly, when the player depresses the touch button 22, the points acquired by defeating the enemy E2 are added to the total points, and when the depressing operation is not performed, points are not added. This completes the one-time production game.

  The effect game in the second special effect mode is an effect game similar to the first special effect mode, and a game screen is displayed on the LCD 9 together with the symbol 23, and the background on the game screen is evening. Depending on the background, the player can determine whether the mode is the first special effect mode or the second special effect mode. If the game including the first special effect mode and the second special effect mode continues for a predetermined number of times (for example, eight times), the game may be forcibly shifted to the normal effect mode.

  As shown in FIG. 2, the sub-control board 32 is provided with a mode random value acquisition unit 41, a mode transition determination unit 42, an effect random value acquisition unit 43, and an effect lottery unit 44.

  The pachinko ball 7 wins at the start winning opening 10 from the time when “2R probability per win”, “2R normal hit”, and “small hit” are selected until the transition to the first special effect mode and during the first special effect mode. Each time, after the winning lottery in the winning lottery unit 31d, the mode random value acquiring unit 41 acquires (lottery) one mode random number value. The mode random value acquisition unit 41 includes a random number generator and a random number sampling circuit, and selects any one of a plurality (for example, “1” to “100”) of random numbers for mode transition by lottery. get. Similarly, in the second special effect mode, the mode random value acquisition unit 41 acquires one mode random value after the winning lottery in the winning lottery unit 31d every time the pachinko ball 7 wins the start winning opening 10. .

  The mode transition determination unit 42 determines whether to transition to the mode or continue the mode based on the acquired mode random value. As shown in FIG. 4, the mode transition determination unit 42 includes a mode transition determination table 46. The mode transition determination table 46 includes data indicating determination results corresponding to random number values “1” to “100”. No. 1-No. 100 determination result data are stored. Each determination result data includes determination result data for the first special effect mode and determination result data for the second special effect mode, respectively. The mode transition determination unit 42 compares the acquired mode random number value with the mode transition determination table 46 to make a determination. If the mode transition determining unit 42 determines that the mode transition is to be performed, the sub CPU 32a performs control for shifting the mode. In the present embodiment, the sub CPU 32a also functions as a mode control unit that shifts modes based on the determination result in the mode shift determination unit 42.

  In the first special effect mode, among the mode random number values “1” to “100”, “1” to “8” become random numbers for transition to the normal effect mode for shifting to the normal effect mode, and “9” and “10”. Becomes a second special effect mode transition random value for shifting to the second special effect mode, and other than these, it becomes a mode continuation random value for continuing the first special effect mode. In the second special effect mode, among the mode random number values “1” to “100”, “1” to “8” are the normal effect mode transition random number values for shifting to the normal effect mode, and otherwise, the second special effect mode. This is a mode continuation random number value that continues the effect mode.

  When the mode transition determining unit 42 determines that the mode is to be continued, the effect random number acquiring unit 43 acquires one random number for effect performed on the LCD 9. The effect random value acquisition unit 43 sends the acquired effect random value to the effect lottery unit 44. The effect random number acquisition unit 43 includes a random number generator and a random number sampling circuit, and each time it is determined that the mode is to be continued, out of a plurality (for example, “1” to “1000”) of random numbers for effect lottery One of these is acquired by lottery.

  When the mode random number acquisition unit 41 acquires the normal effect mode transition random number value or the second special effect mode transition random value, and the mode transition determination unit 42 determines that the mode transition is performed, the effect random number acquisition unit 43 is activated. The mode random value acquisition unit 41 decides to use the acquired mode random value as the production random value and sends it to the production lottery unit 44. In the present embodiment, the mode random value acquisition unit 41 also functions as an identical random value determination unit that determines to use the acquired random value as an effect random value.

  The effect lottery unit 44 draws an effect based on the sent random number value. As shown in FIG. 5, the effect lottery unit 44 includes an effect lottery table 47. In the effect lottery table 47, the data numbers corresponding to the random numbers “1” to “1000” are stored. 1-No. 1000 production data are stored. Each effect data includes normal effect data for the normal effect mode, first special effect data for the first special effect mode, and second special effect data for the second special effect mode.

  The effect lottery unit 44 collates the sent random number value with the effect lottery table 47, and draws effect data, and draws effect data for a mode for performing the effect from the lottered effect data. Based on the lottery effect data, the sub CPU 32a controls the LCD 9 to produce the effect. In the present embodiment, the sub CPU 32a also functions as an effect control means for performing effects drawn by the effect lottery unit 44 on the LCD 9.

  Next, the operation of the pachinko machine 2 configured as described above will be described using the flowcharts of FIGS. As shown in FIG. 6, when the pachinko ball 7 wins the start winning opening 10 (Y in step (hereinafter referred to as S) 1), the winning lottery unit 31d performs a winning lottery (S2). When the winning lottery unit 31d draws “5R probability variation per” or “16R probability variation per” (Y in S3), the process shifts to a probability variation mode (S4). The winning lottery section 31d draws 2R per lot ("2R probable per hit", "2R normal hit", "small hit") (N in S3, Y in S5), and after the game is played per 2 rounds, The CPU 32a shifts to the first special effect mode (S6).

  As shown in FIG. 7, when the pachinko ball 7 wins the start winning opening 10 in the first special effect mode (Y in S7), the winning lottery unit 31d performs a winning lottery (S8). After the lottery in the winning lottery unit 31d, the mode random value acquisition unit 41 acquires one mode random value (S9). The mode transition determination unit 42 collates the acquired mode random number value with the mode transition determination table 46, and transitions the mode (first special effect mode → second special effect mode, first special effect mode → normal effect mode). Whether to continue or continue the mode is determined (S10).

  When the mode transition determining unit 42 determines that the mode is to be continued (N in S11), the effect random value acquiring unit 43 acquires one effect random value (S12). The effect random value acquisition unit 43 sends the acquired effect random value to the effect lottery unit 44. When the mode transition determining unit 42 determines that the mode is to be transitioned (Y in S11), the mode random value acquiring unit 41 determines to use the acquired random number value as the effect random number value (S13), and the effect lottery Send to part 44.

  The effect lottery unit 44 collates the sent random number value with the effect lottery table 47 and draws the effect data. The effect lottery mode is selected from the lottery effect data (the mode to be transferred to when the mode is changed, The effect data for the mode to be continued when the mode is continued) is drawn (S14). The sub CPU 32a performs the mode transition or the mode continuation based on the determination result in the mode transition determination unit 42, and controls the LCD 9 based on the lottery effect data to perform the effect (S15).

  If the winning lottery section 31d has selected “5R probability variation per” or “16R probability variation per” (Y in S16), the process proceeds to the probability variation mode (S17). If the winning lottery section 31d has drawn a lot and the mode is continued (N in S11, N in S16, Y in S18, N in S19), the process returns to (S7). If the winning lottery section 31d has drawn a lottery and the mode has been changed (Y in S11, N in S16, Y in S18, Y in S19), then the mode changed (normal effect mode or second special effect) (Mode) is played (S20). If 2R per lot is selected by the winning lottery unit 31d (N in S16, N in S18), a game is played for two rounds (S21), and then the first special effect mode is entered (S6). In the second special effect mode, the same control as (S7) to (S21) in the first special effect mode is performed.

  As described above, when the mode transition determining unit 42 determines that the mode transition is to be performed, the mode random number value acquired by the mode random value acquiring unit 41 is determined to be used as the effect random number value, and sent to the effect lottery unit 44. Since the random value acquisition unit 43 is not operated, the control for mode transition can be simplified compared to the case where the random number value acquisition unit 43 is operated and the random number value acquisition unit 43 is acquired to obtain the production random number value. It is possible to reduce the load related to the 32 mode transition control.

  In addition, since it is determined whether or not the mode transition is performed with the same probability every game regardless of the control situation on the main control board 31, the probability of mode transition changes according to the control situation on the main control board 31. Compared to a pachinko machine, it is possible to improve the preference in production. For example, regardless of the number of reserved balls displayed on the reserved ball display unit 24, the probability of mode transition can be made the same, and when there are three reserved balls, there are one or zero reserved balls. Compared with a conventional pachinko machine in which the probability of mode transition is low, it is possible to improve the preference in production.

  In the above embodiment, the same mode transition determination table 46 is used in the first special effect mode regardless of whether “2R probability variation hit”, “2R normal hit”, or “small hit” is selected. However, when “2R probability variation hit” is selected, a 2R probability variation mode transition determination table 50 may be used as shown in FIG. In the 2R probability change mode transition determination table 50, in the first special rendering mode, among the mode random numbers “1” to “100”, “1” to “4” are transitioned to the normal rendering mode in which the transition is made to the normal rendering mode. It becomes a random number value, and “5” to “10” are the second special effect mode transition random number values for shifting to the second special effect mode, and other than these are the mode continuation random number values for continuing the first special effect mode. As a result, when “2R Probable Per Change” is drawn and the first special effect mode is shifted, the “2R Normal Win” or “Small Win” is selected and the first special effect mode is selected. The probability of shifting to the second special effect mode is increased.

  Further, in the above embodiment, when the 2R per lot is drawn, the first special effect mode is shifted. However, it is determined whether or not the mode shifts in the normal effect mode or the probability change mode, and the process passes through the 2R. The first special effect mode or the second special effect mode may be shifted to the first special effect mode. Further, when the “2R probability variation hit” is selected and the first special effect mode is shifted to, the first special effect mode may be selected. It may be determined whether or not the mode is changed from the special effect mode to the probability change mode.

  Further, in a game of a predetermined number of times (for example, 10 times) after the transition from the first special effect mode or the second special effect mode to the normal effect mode, it is usually determined whether the game proceeds to the first special effect mode or the second special effect mode. It may be determined whether to continue the effect mode.

  Moreover, in the said embodiment, although the production | presentation by LCD9 was different in normal production | generation mode, 1st special production mode, and 2nd special production mode, you may make it produce production by the speaker 21 etc. in each mode. .
