In addition, a sleeve lamp (not shown), a side lamp (not shown), a decorative lamp / decorative LED (not shown), and the like are provided in the game area 24, together with a display frame upper decorative LED 29a, a display frame left and right decorative LED 29b. At the time of a winning start or a specific game state, the light is turned on or blinks to notify the player of the fact. Further, at the bottom of the game area 24, there is provided an out port 42 through which a hit ball that has not won any of the above-mentioned winning areas is guided to the rear of the game board 18.

The configuration of the back surface of the game board 18 of FIG. 2 is well known, and illustration and details thereof are omitted.
Known members such as various detection sensors, lead wires connected to accessory lamps and lamps, and the like are arranged.
There is also provided a control panel (not shown) that stores
The winning balls which have won the seed starting ports 32, 33 and the lower winning ports 40a, 40b are gathered in a winning path, and a relatively small number of prize balls (for example, 7) are paid out. The balls that have won the other prize ports or the prize areas are gathered in different prize paths to pay out a relatively large number of prize balls (for example, 15).

The characteristic operation of this embodiment will be described with reference to a flowchart shown in FIG. When the ball game machine 17 is connected to a power supply and power is supplied to each circuit from a power supply unit (not shown), the CPU 10 performs a series of initial settings such as a flag and a counter, and executes a main routine (not shown). At the same time, the big hit processing routine is started by a hardware interrupt. First, when the process is started, the process waits for an ON signal of the starting winning ball detector 34 (step S100). When it is determined that there is no ON signal, the process returns to step S100 and repeats the process. On the other hand, when a hit ball wins in the first type starting port 32 or 33, the starting winning ball detector 34 generates an ON signal, so that the affirmative judgment is made, and one random number is obtained from the count values 0 to 19 of the hit / fail determination counter. Select a numerical value and store that value in RAM1
2 is stored. The display of the change of the symbol on the liquid crystal display panel 9, the audio output from the speaker 23, the turning on of various LEDs 29a to 29c, and the like are instructed. The above-mentioned count value stored in the RAM 12 is taken out, and it is determined whether or not the counted value corresponds to the above-mentioned jackpot value.
At this time, the probability variation process is performed in another routine, and in the low probability mode, the hit / fail decision counter is “7”, and the hit / fail decision counter is “7”, “in the high probability mode. 16 "," 17 ",
At the time of “18” or “19”, a big hit is made. When the first big hit processing is completed, the mode shifts to the high probability mode, and when the second big hit processing is ended, the low probability mode is set. I'm going back. In this way, it is determined whether a big hit or a miss has occurred based on the aforementioned count value. In the case of a big hit, the count value of the hit stop symbol determination counter described above is randomly set to 1 from the numerical value of 0 to 10.
Select one of the numerical values, and select one corresponding to this count value.
One hit symbol is determined. On the other hand, in the case of a deviation, one numerical value is randomly selected from the numerical values of the above-mentioned deviation stop symbol determination counter of the count values 0 to 113, and a corresponding deviation symbol is determined according to this count value. Based on those determinations, the symbols are changed, the left symbol display section 6 and the right symbol display section 8 of the liquid crystal display panel 9 are stopped in the order, the reach is displayed, and the middle symbol display section 7 is stopped. The generation of such image data is instructed to the image data processor 4 (step S101). Next, it is determined whether the combination at the time of the stop is the display mode of the above-mentioned big hit symbol (step S102). If an affirmative determination is made in step S102, the specific game state is established, and the image data processor 4 reads out the image data of the jackpot from the image data ROM 3, and “3” according to the characteristic jackpot method of the present embodiment.
A special symbol display of a big hit symbol such as “45”, “357”, “367” is displayed on the liquid crystal display panel 9 and the speaker 23 is displayed.
Output of the jackpot sound from the player, turning on the various LEDs 29a to 29c, and the like, and opening the special winning opening 36 for a predetermined time, during which the hit ball falling in the game area 24 is moved to the specific area 3
Big hit processing, such as accepting in step 7 (step S1)
03). Subsequently, it is determined whether or not the jackpot process has been completed (S104). If it is determined that the jackpot process has not been completed, the process returns to step S103 and returns to step S10.
Step 4 is repeated. If it is determined in S104 that the jackpot process has been completed, the process returns to the return. On the other hand, if a negative determination is made in step S102, a predetermined departure process (S105) is performed, and the process exits the return.

By configuring the present embodiment as described above, a player who plays a game with the ball game machine according to the present embodiment in a game hall where the big hit symbol is almost double-shaped, The effect is that a fresh feeling of contact is obtained and the interest is further enhanced. In addition, there is an effect that the sense of expectation of the big hit is increased by the difference of the big hit expected value depending on the display symbol at the time of the reach. That is, in the case of "7", "X", and "7", which are the jackpot reach displays that have the same three-digit value, when the middle symbol "X" stops at "7", a jackpot is established, so the jackpot expected value is 1 / 5, in the case of the characteristic big hit method of the present embodiment, the reach display is “3” “X”
In the case of "7", the middle symbol "X" is "4", "5",
If you stop at any one of "6", you will get a big hit,
The big hit expected value is 3/5, and the reach display is "3"
In the case of “X” and “6”, the middle design “X” is “4”,
If it stops at any of "5", it will be a big hit, so the big hit expected value will be 2/5 and reach display will be "3""X"
In the case of "5", if the middle symbol "X" stops at any of "4", a big hit will occur, so the big hit expected value will be 1/5. The predictability has the effect of increasing the jackpot expectation.

Next, a description will be given of another embodiment provided with a liquid crystal display panel 59 shown in FIGS. 4 (a) and 4 (b) in which the screen configuration of the liquid crystal display panel 9 of the ball game machine 17 is different. The liquid crystal display panel 59 has three digit left, middle, and right symbol display units 56 to 5 capable of variably displaying ten types of characters from 0 to 9 respectively.
Symbol display section 6 having a relatively large screen provided with
0, and a lower inconspicuous screen on the lower right side, which is a three-digit left, middle, and right special design that can variably display 15 types of characters 0 to 9 and A to E, respectively. And a main symbol display section 61 having symbol display sections 66 to 68. The big hit symbols of the main symbol display section 61 are 000, 111, 222 to 999, AAA to EEE
And the three digits are the same, and whether or not a big hit is determined by a random number. The random number for this jackpot is periodically incremented and repeatedly generated.
It is composed of 225 kinds of numbers consisting of values of ~ 224
It is taken out when the game ball has won the first kind starting port 32 or 33. In the present embodiment, when the extracted value is “1”, a big hit is determined. Therefore, the jackpot probability is 1/225. On the other hand, the symbols displayed on the left, middle, and right symbol display portions 66 to 68 of the main symbol display portion 61 are each determined by a symbol determination random number including 15 types of numbers 0 to 14. Therefore, the probability that the same three-digit symbol is displayed on the display is 1 / 15X1 / 15X1 / 15X15 =
1/225, which is equal to the probability of the random number. In the present embodiment, when the value of the pass / fail decision random number is “1”, the same three-digit symbol is forcibly displayed on the symbol display unit. When the value of the pass / fail decision random number is other than “1”, the symbol random number (0 ~ 14)
Are displayed so as to display symbols (0 to 9, A to E) corresponding to. When a symbol having the same three digits is displayed by the symbol random number even though it is not a big hit, a process for forcing the same three digits is performed. The main symbol display unit 61 has various restrictions in the game rules, for example, a restriction such that the probability of the jackpot on the display and the probability of the random number for determining the success or failure is within ± 10%, or the method of the fluctuation must be a certain movement. There is. In order to solve this restriction and ensure the interest of the player, the hit / fail display of the main symbol display 61 and the hit / non-right display of the pseudo symbol display 60 are made to correspond one-to-one, and the main symbol display is displayed on the pseudo symbol display 60. The role as the unit 61 is given, and the player
It is to be determined whether or not a big hit is seen by looking at 0. This pseudo symbol display unit 60 is configured to perform a fluctuation and stop display in conjunction with the main symbol display unit 61,
The big hit symbols are set in the same manner as in the above-described embodiment, and the number of the stopped symbols after the change displayed on the middle symbol display unit 57 is the left symbol display unit 56 and the right symbol display unit 58.
Are within the range of numbers indicated by the respective stop symbols, and the numerical values shown in the left symbol display portion 56 <the numerical values shown in the middle symbol display portion 57 <the numeric values shown in the right symbol display portion 58, in ascending order. Holds, that is, the stop symbol is [12
3], [124], [134] ... [679],
If it corresponds to the symbol arrangement of [689] and [789], they are set so as to be a big hit arrangement, and the other symbols are set to be off symbols.

The display operation of the liquid crystal display panel 59 of the above embodiment will be described. In the case of the big hit symbol shown in FIG. 4 (a), after changing the symbol in response to the entering of the game ball into the first kind starting ports 32 and 33, the CPU 10 causes the pseudo symbol display unit 60 and the main symbol to change. The big hit stop symbols on the display unit 61 are “1”, “5”, “9”, and “7”, “7”, “7”, respectively.
Is determined, the left symbol display unit 56 and the right symbol display unit 58 of the pseudo symbol display unit 60 are stopped to reach display, and then the middle symbol display unit 57 is stopped. Simultaneously or slightly later, the left symbol display 66 and the middle symbol display 67 of the main symbol display 61 are stopped to reach the display, and the right symbol display 68 is stopped. In the case of the off symbol shown in FIG. 4 (b), after the symbol change is started in the same manner as described above, the CPU 10 sets the pseudo symbol display section 60 and the main symbol display section 61 to "1" and "9" respectively.
"9", "7", "7", "6" are determined, the left symbol display unit 56 and the right symbol display unit 58 of the pseudo symbol display unit 60 are stopped, reach display is performed, and then the middle symbol display unit 57 is stopped. In the case of the out-of-reach display or the out-of-reach display, the left symbol display unit 56, the middle symbol display unit 57, and the right symbol display unit 58 are sequentially stopped. Simultaneously or slightly later, the left symbol display section 66 and the middle symbol display section 67 of the main symbol display section 61 are stopped and reach display is performed, and then the right symbol display section 68 is stopped to reach out-of-reach display. Or in the case of non-reach-off display, the left symbol display section 66, the middle symbol display section 67, and the right symbol display section 68 are sequentially stopped. Although the pseudo symbol display unit 60 is represented by Arabic numerals, this is an animation scene representing a horse race, and whether or not a big hit is determined based on the horse number (bib number) attached to the finished horse. Can be displayed, and in this case, there is an effect that the degree of freedom of displaying the success or failure of the big hit is increased, and the interest of the player is further enhanced.

Although the present embodiment has been described above, it is obvious that the design of the configuration of the present invention can be changed as appropriate without departing from the technical idea of the present invention. It belongs to the range. For example, the present invention can be applied to other types of ball game machines such as so-called right models, arrangement ball game machines, and time reduction machines. Further, in the above-described embodiment, when the numerical value indicated by the left symbol display unit 6 <the numerical value indicated by the middle symbol display unit 7 <the numerical value indicated by the right symbol display unit 8> is established in an ascending order, the symbol is set as a big hit symbol. In contrast to this, the numerical value indicated by the left symbol display unit 6>
When the numerical value indicated by the middle symbol display unit 7> the numerical value indicated by the right symbol display unit 8 satisfies the descending order of magnitude, it is also possible to set a large hit symbol. The symbols on the left symbol display section 6, the symbols on the middle symbol display section 7, and the symbols on the right symbol display section 8 are set to integer values such as 3 to 7, but are not limited thereto. Pie pattern (for example, 4 for Supin), card pattern (for example, 1 for KING)
3) It is also possible to indicate a shogi stage (for example, 8 for eight stages). The hit mode according to the characteristic configuration of the present embodiment is a combination with the hit symbol of "777", but it is also possible to configure the big hit display mode alone without the slot, It is also possible to combine with the big hit form which consists of a pattern of the same pattern instead of a slot. Further, the liquid crystal display panel 9 can be replaced with a drum type rotary display device. In addition, a three-row, three-column display form is naturally possible in place of the three-digit connected display section, and a configuration showing the above-mentioned big hit mode in a vertical line, a horizontal line, and an oblique line is also possible. .
