Description

  The present invention relates to a gaming machine that controls a display mode of a symbol display device that displays whether or not a special winning state that gives a player a certain privilege by combining symbols is generated.

  Conventionally, as this type of gaming machine, for example, a symbol display device in which three rows of display areas are provided in the horizontal direction on a game board surface or a plurality of display areas are provided in a matrix is known. Variable display is performed by rotating a drum or electrically driving a display screen such as a liquid crystal display. Then, by entering the game ball into a specific entrance such as a start opening or passing gate provided on the game board surface, the symbol display device starts to display variable characters, numbers, symbols, etc. After the change in time, the display is stopped, and the same characters etc. are aligned in the vertical and horizontal directions and the diagonal direction by the combination of the stationary symbols, so that it shows a so-called big hit state where a certain privilege is given. It was.

  In the above conventional design, the symbol display mode such as the start of symbol variation, reach operation, display method until symbol variation stop, variation time, symbol arrangement, symbol determination order, etc. are constant and the display form is simple. The display itself was monotonous. Therefore, there is almost no element for the player to enjoy the process from the start of symbol variation to the special winning state, and there is room for improvement in the symbol display form in this respect.

  An object of the present invention is to provide a gaming machine capable of changing the display mode in the process from the start of symbol variation to the special winning state.

  The gaming machine according to claim 1 is provided on the game board surface based on the counter value obtained by acquiring a jackpot counter according to the game ball entering the specific entrance provided on the game board surface on the front surface of the main body. In a gaming machine that causes the symbol display device to perform symbol display according to a prescribed display mode and stop display, the same number of rows and columns is formed based on the counter value obtained by forming the same number of columns and rows of symbol display areas. No matter what counter value is obtained by setting the symbol data displayed in the multiple-column multiple-row symbol display area, after the start of fluctuation, the same number of vertical and horizontal multiple columns from multiple rows to the outer column rows are arranged in 2 rows and 2 columns Only the reduced display area is formed on the display screen, and only the symbols corresponding to the display area reduced by 2 rows and 2 columns from the multiple rows of the same number of rows and columns from the same number of rows and columns are read out and displayed in the display screen. A display area in which the number of outer rows from two or more columns is reduced by 2 rows and 2 columns is reduced in the center of the display, and the same number of vertical and horizontal display areas of 2 rows and 2 columns are formed on the display screen. It is characterized in that there is a control circuit that controls to read only symbols corresponding to the display area of the same number of rows and columns of 2 rows and 2 columns around it and to perform stop display.

  According to the gaming machine of the first aspect, the variable display is started in each display area of the symbol display device based on the entrance of the game ball into the specific entrance. At this time, since the display mode can be controlled so as to be changeable for each variable display unit, the display form is very complicated, so that the symbol variable display itself is made rich in variety. Therefore, since the player can encounter various changes during symbol variation, he / she can enjoy the process from the symbol variation start to the variation stop. Moreover, even if the special symbol is not displayed due to the stationary symbols displayed after the variation display of the symbol display device is stopped, the stationary symbols are reduced, the variation display of the surrounding display area is started, and the second variation display is performed. After the stop, it is displayed again whether or not it is in the special winning state. For this reason, the player is given the opportunity to determine the special prize state twice, so that the entertainment of the game can be enhanced, and the display area can be changed and the display can be varied and decorated.

  The starting opening winning memorized number display section 22 is composed of four light emitting diodes, and displays a maximum of four results when a game ball wins at any starting opening while the special symbol display device 21 is in a variable display. Thus, after the symbol variation display is completed, a display indicating that the next symbol variation display is promised is performed. The fifth winning ball is an overflow ball and is not involved in the variable display of the special symbol display device 21. In addition, about the start opening prize memory | storage number display part 22, it can also be set as a digital display.

  Next, an electric control device for performing display control of the pachinko gaming machine will be described with reference to FIG. The electric control device 50 is provided on a part of the main board 42 and the prize ball board 48, and is provided with a control circuit 51 including a microcomputer including an I / O, a CPU, a ROM, a RAM, a timer, and the like. . The control circuit 51 continues to execute the “special symbol display program” and the “variation start order change routine” corresponding to the flowcharts shown in FIGS. 5 to 7, and the “start opening prize memory number display” corresponding to the flowchart shown in FIG. 8. Execute “Program” interrupt. In addition, the control circuit 51 stores “special symbol display program”, “variation start order change routine” and “start opening prize storage number display program” in the ROM, as well as jackpot determination data, loss reach determination data, jackpot symbol data. , A map of missed reach symbol data, missed symbol data, and the like, a starting opening prize memorized number reference value N0 and the like are stored.

  Also, the control circuit 51 determines the probability counter Ia for determining the jackpot state, the jackpot symbol counter Ib for determining the jackpot symbol, the outlier symbol area counter IIa for determining whether it is in the missed reach state or the missed state, and determines the missed reach symbol An outlier reach symbol counter IIb, an outlier symbol counter IIc that determines other outlier symbols, a change start order change counter III (not shown), and the like are provided. The probability counter Ia repeatedly counts up a numerical value of 0 to 742, for example, and the value is compared with the big hit determination data. The jackpot symbol counter Ib repeatedly counts up a numerical value of, for example, 0 to 15, and this numerical value corresponds to the jackpot symbol data. The missed symbol area counter IIa repeatedly counts up a numerical value of, for example, 0 to 12, and the value is compared with the missed reach determination data. The outlier reach symbol counter IIb repeatedly counts up a numerical value of, for example, 0 to 209, and this numerical value corresponds to the outlier reach symbol data. The off symbol counter IIc repeatedly counts up a numerical value of 0-2729, for example, and this numerical value corresponds to the above off symbol data.

  For example, the change start order change counter III repeatedly counts up a numerical value of, for example, 0 to 5, and this numerical value indicates whether the variable display starts from the left display area 21a, the central display area 21b, or the right display area 21c. It corresponds to the combination of the order. Regarding the relationship between the count value Z of the counter III and the change start order, for Z = 0,..., 5, left-right-middle, left-middle-right, middle-left-right, middle-right, respectively. -Left, right-left-middle, right-middle-left (the description of the display area is omitted).

  As shown in FIG. 4, the start port switches 15a, 16b1, 16c1 and the big prize port switch 16a1 are connected to the input side of the control circuit 51. The output side of the control circuit 51 is connected to a special symbol display device 21 provided on the symbol display board 20 and a start opening prize memory number display unit 22.

  Next, the operation of the basic configuration configured as described above will be described. When the power switch (not shown) is turned on, the control circuit 51 starts execution of the “special symbol display program” at step 60 shown in FIG. 5 and performs initialization processing of various variables at step 61. Then, in step 62, the probability counter Ia, jackpot symbol counter Ib, missed symbol area counter IIa, missed reach symbol counter IIb, missed symbol counter IIc and variation start order change counter III start counting from 0. Repeat counting up. At the same time, the control circuit 51 starts interrupt execution of the “start opening prize memory number display program” in step 90 shown in FIG. 8 and initializes the starting opening prize memory number N to “0” in step 91. . The game is started by operating the launch handle 33, and the launched game ball passes through the guide rail 13a and is supplied into the game area 11a.

  The control circuit 51 determines in step 92 shown in FIG. 8 whether or not the game ball has won any of the start ports 15, 16b, 16c. When the game ball has not won any of the start openings 15, 16 b, 16 c, the program is moved to step 94 based on the determination of “NO”, and the display areas 21 a to 21 c of the special symbol display device 21 are displayed. It is determined whether or not fluctuation display is in progress. When the variable display is not being performed, the program is moved to step 95 based on the determination of “NO”, and it is determined whether or not the start opening prize storage number N is zero. When N = 0, the program is returned to step 92 based on the determination of “YES”, and the processing of step 92 to step 95 is repeated.

  When the game ball wins at any start opening, the program is moved to step 93 based on the determination of “YES” at step 92 and the start opening winning memorized number N is incremented by “1”. The program is moved to step 96 based on the determination of “NO” in step 94 and step 95. When the symbol variation is started, the program is moved to step 97 based on the determination of “YES”, and the starting opening prize storage number N is decremented by “1” and N = 0. Next, at step 98, it is determined whether or not the start opening prize memory number N is 4 or more. At this time, since the start opening prize memory number N = 0, the program is moved to step 99 based on the determination of “NO”, and the start opening prize memory number display section 22 displays the start opening prize memory number N. . Here, in accordance with N = 0 shown in step 97, the lighting display at the start opening winning memorized number display unit 22 is not performed. Next, in step 100, it is determined whether or not the gaming machine is in a big hit state. Usually, since it is not in the big hit state, the program is returned to step 92 based on the determination of “NO”, and the processing after step 92 is performed. When a game ball is won at any of the start ports 15, 16b, 16c during the symbol variation display, the program goes to step 98 based on the determination of "YES" in step 94 after step 92 and step 93. Moved. Then, based on the determination of “NO” in step 98, the program is moved to step 99, and one lighting display is performed on the start opening prize storage number display unit 22 in accordance with N = 1.

  Further, when the starting opening winning memorized number N becomes larger than “4”, the program is moved to step 101 based on the determination of “YES” in step 98, and the starting opening winning memorizing number N = 4 is set. At 102, four lighting displays are performed on the start opening winning memorized number display section 22. In other words, the maximum number N of start opening winning memorization is defined as “4”, and even if it is larger than 4, a number of 5 or more is excluded as an overflow number. If the gaming machine is in a big hit state during the execution of step 92 to step 100, the program is moved to step 103 based on the determination of “YES” in step 100, and the N value processing routine in the big hit is executed. Is called. When the big hit state is finished, the program is moved to step 104 and the execution of the program is finished.

  On the other hand, the control circuit 51 reads the start opening prize storage number N in step 63 shown in FIG. 5 and determines in step 64 whether the start opening prize storage number N = 0. Since N = 0 at the time immediately after the start of the game, the program proceeds to step 65 based on the determination of “YES”, and it is determined whether or not the game ball has won any of the start ports 15, 16b, 16c. . When the game ball wins one of the start ports 15, 16b, 16c, the control circuit 51 receives the input signal from the start port switches 15a, 16b1, 16c1, and the control circuit 51 executes the program based on the determination of "YES" in step 66. Then, the value X of the probability counter being counted up is read. Further, at step 67, a “variation start order changing routine” is executed.

  In the “variation start order change routine”, execution of the program is started at step 80 shown in FIG. 7, the count value Z of the change start order change counter III is read at step 81, and the count value Z is set at step 82. The corresponding variation start order is selected. Accordingly, the first, second, and third display signals are output to the display areas 21a to 21c according to the order selected in steps 83x to 85x (x = a to f). The display is started in order, and the program ends at step 86 and returns to the main routine. As described above, since the change start order for each of the display areas 21a to 21c is changed every time the change display of the special symbol display device 21 is started, it is possible to enjoy display changes and diversity at the start of display.

  Next, in step 68, the timer starts measuring time, and in step 69, it is determined whether or not time t0 has elapsed. When the time t0 has elapsed, the program moves to step 70 based on the determination of “YES”, and it is determined whether or not the read value X of the probability counter Ia corresponds to the big hit. Since it is normally out of order, the program is moved to step 71 shown in FIG. 6 based on the determination of “NO”, and the value H of the out-of-order symbol area counter IIa at that time is read.

  Next, in step 72, it is determined whether or not the value H is a numerical value of the detachable symbol area 1 in a detachable reach state. If it is not out of reach, the program moves to step 73 based on the determination of “NO”, and a predetermined off symbol Hx is selected from the off symbol map. The display areas 21a, 21c, and 21b are stopped in this order, and the off symbol Hx is displayed on the special symbol display device 21. Thereafter, the program is returned to step 63, and the processing after step 63 is performed.

  On the other hand, if the control circuit 51 executes the “special symbol display program” and H is selected in step 72 as being in the detachable symbol area 1, the determination is “YES”. The program is moved to step 75, and a predetermined outlier reach symbol HR is selected from the outlier reach symbol map. In step 76, the variable symbol display on the special symbol display device 21 is stopped in the order of the left and right display areas 21a, 21c, 21b. , The unreachable symbol HR is displayed on the special symbol display device 21. Thereafter, the program is returned to step 63, and the processing after step 63 is performed.

  Next, when the control circuit 51 determines that the value X read from the probability counter Ia in step 66 is a big hit in step 70, the program is moved to step 77 based on the determination of “YES”. The jackpot symbol Oa is selected from the jackpot symbol counter Ib, and the jackpot symbol Oa is displayed on the special symbol display device 21 at step 78. When the big hit state is completed, the program is returned to step 65 based on the determination of “YES” in step 79, and the processing from step 65 onward is restarted as described above.

  Next, an embodiment of the present invention will be described. In the embodiment of the present invention, as shown in detail in FIG. 9, the special symbol display device 53 is provided with nine display areas 53a to 53i in a matrix shape that are partitioned into three rows and three columns of a liquid crystal display type. In this display device, the symbols are variably displayed for each of the display areas 53a to 53i. As each symbol, for example, 10 numbers from 1 to 0 and 5 symbols such as heart, spade, diamond, etc. are used. Then, the special symbol display device 53 finishes the variable display, and when the stationary symbols are displayed in the nine display areas 53a to 53i as shown in FIG. As shown in FIG. 10 (b), the nine display areas 53a to 53i are reduced and collected at 3/5 in the center of the screen. The screen is divided into a central screen 53C composed of aggregated display areas 53a ′ to 53i ′ and a peripheral screen 53S composed of 16 display areas 54a ′ to 54p ′ surrounding the central screen 53C. Then, the surrounding screen 53S is again displayed in a variable manner, and as shown in FIG. 10C, when the fluctuation stops, the shape of the centralized screen 53C and the surrounding screen 53S are combined. It is configured to determine whether or not a big hit. That is, the big hit determination is made in two stages.

  Further, the control circuit 51 of the electric control device 50 continues to execute the “special symbol display program III” corresponding to the flowcharts shown in FIGS. 11 to 13 and displays the “start opening prize memory number display” corresponding to the flowchart shown in FIG. Execute “Program” interrupt. In addition, the control circuit 51 stores the “special symbol display program III” and the “start opening prize memorized number display program” in the ROM, as well as jackpot determination data, missed reach determination data, jackpot symbol data, missed reach symbol data, missed A map of symbol data and the like, and a starting opening prize memory number reference value N0 are stored. The jackpot symbol data, outlier reach symbol data, and outlier symbol data map are divided into a portion corresponding to the data displayed on the central screen 53C and a portion corresponding to the data displayed on the surrounding screen 53S. Each corresponding part is read out. Other configurations are the same as the basic configuration.

  Next, the operation of the embodiment of the present invention configured as described above will be described. When the power switch (not shown) is turned on, the control circuit 51 starts the execution of the “special symbol display program III” in step 180 shown in FIG. 11 and performs initialization processing of various variables in step 181. In step 182, the probability counter Ia, the big hit symbol counter Ib, the missed symbol area counter IIa, the missed reach symbol counter IIb and the missed symbol counter IIc start counting from 0 and repeatedly count up each numerical value. At the same time, the control circuit 51 performs the interrupt execution of the “start opening prize memory number display program” as shown in the basic configuration. The game is started by operating the launch handle 33, and the launched game ball passes through the guide rail 13a and is supplied into the game area 11a.

  The control circuit 51 reads the start opening prize storage number N in step 183 shown in FIG. 11 and determines in step 184 whether or not the starting opening prize storage number N = 0. Since N = 0 at the present time, the program proceeds to step 185 based on the determination of “YES”, and it is determined whether or not the game ball has won any of the start ports 15, 16b, 16c. When the game ball wins one of the start ports 15, 16b, 16c, the control circuit 51 receives the input signal from the start port switches 15a, 16b1, 16c1, and the control circuit 51 executes the program based on the determination of "YES" in step 186. Then, the value X of the probability counter being counted up is read. Further, in step 187, a symbol variation display signal is output, and the special symbol display device 53 starts variation display.

  Next, in step 188, the timer starts measuring time, and in step 189, it is determined whether time t01 has elapsed. When the time t01 elapses, the program is moved to step 190 based on the determination of “YES”, and it is determined whether or not the read value X of the probability counter corresponds to the jackpot. Since it is normally out of order, the program moves to step 191 based on the determination of “NO”, and the value H of the out-of-sequence symbol area counter IIa at that time is read. Next, at step 192, it is determined whether or not the value H is a numerical value of the off symbol area 1 in the off-reach state. If it is not out of reach, the program proceeds to step 193 based on the determination of “NO”, and a predetermined out-of-sequence symbol HX is selected from the out-of-sequence symbol map. In step 194, the symbol variation display is displayed in the display areas 53a to 53a. The portion HX ′ corresponding to the data displayed on the central screen 53C of the off symbol Hx is displayed on the special symbol display device 53. Thereafter, the program is moved to step 195, where the display areas 53a to 53i are reduced to the screen center screen 53C and consolidated into display areas 53a 'to 53i'. Next, in step 196, a variable display is performed on the surrounding screen 53S. Then, after the time t02 has elapsed, the program is moved to step 198 based on the determination of “YES” in step 197, and the variable display on the surrounding screen 53S is stopped. Here, since it is not in the big hit state, after the shifted symbol is displayed on the special symbol display device 53, the program is moved to step 183, and the processing after step 183 is performed.

  On the other hand, if the control circuit 51 executes the “special symbol display program” and H is selected as being in the detachment symbol area 1 in step 192, the determination is “YES”. The program is moved to step 199, and a predetermined outlier reach symbol HR is selected from the outlier reach symbol map. In step 200, the variable display of the special symbol display device 53 is stopped in the display areas 53a to 53i, and the outlier reach symbol is displayed. A portion HR 'corresponding to the data displayed on the central screen 53C of HR is displayed on the special symbol display device 53. Thereafter, the program is moved to step 201, and the display areas 53a to 53i are reduced to the screen center screen 53C and aggregated into display areas 53a 'to 53i'. Next, in step 202, a variable display is performed on the surrounding screen 53S. Then, after the time t02 has elapsed, the program is moved to step 204 based on the determination of “YES” in step 203, and the variable display on the surrounding screen 53S stops. Here, since it is not in the big hit state, after the shift reach symbol HR is displayed on the special symbol display device 53, the program is moved to step 183, and the processing after step 183 is performed.

  Next, during execution of the “special symbol display program III” by the control circuit 51, when the value X read from the probability counter in step 187 is determined to be a big hit in step 190 at the start of symbol variation in step 186. Based on the determination of “YES”, the program is moved to step 205 shown in FIG. 13 and the jackpot symbol Oa is selected from the jackpot symbol counter Ib. Further, in step 206, the symbol variation display of the special symbol display device 53 is stopped in the display areas 53a to 53i, and the portion Oa 'corresponding to the data displayed on the central screen 53C of the jackpot symbol Oa is displayed in the special symbol display device 53. Is displayed. When the symbols displayed in the display areas 53a to 53i display a big hit, the program is moved to step 212 based on the determination of “YES” in step 207, and the end of the big hit state is awaited. When the symbols displayed in the display areas 53a to 53i do not display a big hit, the program moves to step 208 based on the determination of “NO”, and the display areas 53a to 53i are reduced to the screen center screen 53C. The display areas 53a 'to 53i' are collected. Next, in step 209, the variable screen is displayed on the surrounding screen 53S. Then, after the elapse of time t02, the program is moved to step 211 based on the determination of "YES" in step 210, the variable display on the surrounding screen 53S is stopped, and the big hit symbol Oa is displayed. When the big hit state is completed, the program is returned to step 185 based on the determination of “YES” in step 212, and the processing after step 185 is newly restarted as described above.

  As described above, in the embodiment of the present invention, the static symbol displayed after the stop of the variable display of the special symbol display device 53 is reduced and displayed on the central screen 53S even when the big symbol is not hit. Then, the variable display is started on the surrounding peripheral screen 53S, and after the second variable display is stopped, whether or not the big hit state is again displayed.
