Enter and pass behind the game board 5. When the game ball enters the starting gate 23 below the variable symbol display means 12, the variation processing means 31 works to vary the symbol of each symbol display section 27, and each symbol display section 27 when a certain variation time elapses. Stop the symbols in the order of left / right / middle.

That is, the random number generating means 29 is always from 0 to 2
When random numbers up to 49 are generated and the starting gate 23 detects a game ball, the random number determination means 30 reads and determines the random number at the time of detection, and the variation processing means 31 performs variation processing according to the determination result of the random number. The design of each symbol display unit 27 of the variable symbol display means 12 is changed for a certain period of time.

When the fluctuation processing means 31 starts fluctuation processing,
The symbol determination means 32 is a variable symbol display means 12 of each symbol display section 27
The stop pattern of is determined. Then, if the stop symbol of each symbol display unit 27 is other than a hit random number that is a winning symbol, the symbol determining unit 32 determines that the symbol is out, and the specific winning unit 18 is not opened.

When each symbol display unit 27 of the variable symbol display means 12 is stopped by a winning symbol, the specific winning means 18 is opened by a signal from the symbol determining means 32, and when the game ball passes through the special operation area 28, it is a big hit. The generating means 33 operates to generate a jackpot state advantageous to the player.

That is, if the game ball passes through the special operation area 28 of the specific winning means 18, after that, every time the game ball enters the third class starting opening, the big winning means 20 is opened for a certain time, and this big winning is made. Since the means 20 repeats the opening / closing operation up to 16 times, a large number of game balls enter the big winning means 20 in succession, and each 15 of the game balls has 15 game balls as a prize payout means 34. It is paid out to the upper plate 6 and returns a great profit to the player.

On the other hand, the game ball that has passed the starting gate 23,
In most cases, the player will drop downwards and win the lower winning opening 24. Then, every time one game ball is won in the lower winning opening 24, the payout means 34 pays out seven game balls as prizes. When the starting gate 23 detects the passage of the game ball, the first counting means 36 sequentially counts it and detects the game ball within a unit time in the game, for example, about 1 minute, 3 minutes or 5 minutes. The number (number of winning prizes) is sequentially calculated.

When the game ball is launched by the launching means 8 to the upper part of the game board 5 and consumed, the game ball wins at the top winning port 15 or the like, or enters the out port 22 and goes to the rear side of the game plate 5. It will be recovered to the detector switch during the recovery process.
37 detects the game ball. Then, each time the detection switch 37 detects a game ball, the second counting means 38 counts it, and the game ball is consumed within a unit time in the game, for example, about 1 minute, 3 minutes or 5 minutes. The number is sequentially calculated.

When the respective counting means 36, 38 respectively count, in the calculating means 39, the number of detections counted by the first counting means 36 and the payout means 34 pays out in one payout operation when a prize is paid to the lower winning opening 24. The actual number of payouts of the game balls within a unit time at that time, for example, about 1 minute, 3 minutes, or 5 minutes is calculated from the number of payouts 7, and the number of payouts and the game balls counted by the second counting means 38. Then, the ratio of the two in the unit time at the time of the game is calculated from the consumption number of.

For example, if 100 game balls are shot in 1 minute and 5 of these game balls pass through the starting gate 23, all of the 5 game balls will be won in the lower winning opening 24. Assuming that these 5 prizes will give you 35
The individual game balls are paid out from the payout means 34. on the other hand,
When designing the arrangement of obstacle nails, etc. on the game board 5, while the five game balls pass through the starting gate 23, the game balls enter the other upper winning openings 15, etc., and the average number of games is about five. Design the ball to be paid out. Therefore, in this case, apart from the actual payout number of the game balls, the payout number of the game balls is about 40 from the calculation at the time of design.

Therefore, the calculation means 39 adds 5 to 35 pieces by the other winning means to calculate the payout number of 40 pieces, and calculates a ratio of 40% to the consumed number of 100 pieces. When the calculation means 39 calculates 40%, the display control means 40 operates to turn on or blink the four light emitting parts 26 from the lower side of the level display means 25 inside the left and right corner lamps 21 continuously. Then, the ratio of the number of payouts to the number of consumptions at that time, that is, the return rate is displayed according to the level of the lighting level. If the number of game balls passing through the starting gate 23 increases or decreases thereafter, the display of the level display means 25 changes up or down accordingly.

Therefore, by looking at the lighting state of each of the light emitting portions 26 of the level display means 25, the player can relatively easily grasp the extent of the reduction rate per unit time at that time by changing the level in five steps. It is possible to arouse the player's thinking. Further, since the light emitting portion 26 of the level display means 25 is lit and displayed in five stages, the decorative effect is large as compared with the case where the numbers are directly displayed digitally. Therefore, the level display means 25 can simultaneously perform illumination-like decoration on the board surface of the game board 5 and display the ratio to the player.

When the jackpot state is reached, the display control means 40 operates to turn on all the light emitting parts 26 of the level display means 25 to perform full display. Therefore, when the big hit occurs, the illumination effect of the board surface becomes good, and it is possible to produce the big hit in combination with other sounds.

FIG. 5 illustrates a second embodiment of the present invention, in which the ratio of the number of payouts to the number of game balls consumed is calculated based on the time interval when the game balls pass through the starting gate 23. It is the one. That is, the clock is always generated from the clock generation means 41, and the clock generated from the clock generation means 41 is counted by the starting gate 23 between the detection of the game ball and the detection of the next game ball. Count at 42 to measure the time interval. Then, the calculating means 39 calculates the number of payouts according to the time interval,
The ratio of the calculated payout number to the consumed number is calculated and displayed on the level display means 25.

Thus, even if the time interval at which the starting gate 23 detects a game ball is measured, it is possible to easily obtain the payout number of the game ball at that time from the time interval and calculate the ratio. is there. In this case, the average time interval when the starting gate 23 detects the game ball several times is calculated,
The payout number of gaming balls at that time may be calculated.

6 and 7 exemplify a third embodiment of the present invention, in which level display means 25 are provided on both left and right sides of the display case 43 of the variable symbol display means 12. The display case 43 is provided with an eaves portion 44 on the upper side, and three symbol display portions 27 are provided on the lower center of the eaves portion 44. Then, arc-shaped level display means 25 having five light emitting portions 26 are arranged on both left and right sides of the three symbol display portions 27.

Also in the case of this embodiment, the display control means 40
Thus, the respective light emitting portions 26 of the left and right level display means 25 are appropriately turned on, and the ratio of the number of payouts to the number of consumptions can be displayed as a level. In particular, since the variable symbol display means 12 is arranged in the central portion of the game board 5, the display state of the level display means 25 can be easily seen.

8 and 9 illustrate a fourth embodiment of the present invention, in which a liquid crystal display hand portion 45 is provided at the center of the display case 43, and the level display means is provided by utilizing the lower portion of the liquid crystal display portion 45.
25 is provided laterally in a strip shape. In this case,
The band-shaped level display means 25 is appropriately divided, and the ratio can be displayed as a level according to the length of the length so as to extend from the center to the left and right sides or to extend from the left and right one end side to the other end side.

FIG. 10 illustrates the fifth embodiment of the present invention, in which the level indicator 25 is constituted by the corner lamp 21 and the inner indicator lamp 50 inside thereof. Inside the corner lamp 21, five light emitting lamps 51 are provided in the vertical direction, and also the inner display lamp 50 is provided with five light emitting lamps 52 in the vertical direction.

In this case, the number of consumed and paid out game balls is counted even during the big hit operation after the occurrence of the big hit, and the ratio of the paid out number to the consumed number is calculated by the calculating means 39 from each of the count values. Then, in a normal case other than the jackpot, the maximum reduction rate is about 50%, so that the corresponding light emitting lamps 52 of the inner display lamps 50 are sequentially turned on from the lower side in accordance with the ratio calculated by the calculating means 39. Display the ratio. If the number of payouts increases during the jackpot operation and the ratio exceeds 60%, the corresponding light emitting lamps 51 of the corner lamps 21 are sequentially turned on from the lower side while the respective light emitting lamps 52 of the inner display lamp 50 are kept on. Then, each ratio from 60% to 100% is displayed. Therefore, in this case, it is possible to display each ratio from 10% to 100%.

In this way, the inner display lamp 50, which is relatively easy to see, is normally turned on, so that it is easy to check the ratio. Further, during the jackpot operation, since the ratio is displayed by using the corner lamp 21 in combination with the inner display lamp 50, the ratio can be displayed by accurately reflecting the game ball actually paid out from the payout means 34.
