It is detected by 11b and 11c. Based on the detection output, when a plurality of types of symbols are variably started by the display screen 70 of the variable display device 3 and then stop control is performed, and the display result at the time of stop becomes a specific display mode as described later, The open / close plate 6 of the variable winning ball device 4 is opened to enter the first state advantageous to the player. This open / close plate 6 is a solenoid 1
In the normal state where 3 is not excited, it is closed and is in the second state which is disadvantageous to the player, but the solenoid 1
3 is excited to open and enter the first state.

The 10-count detector 9 detects a pachinko ball that has won the winning opening 5 of the variable winning ball device 4 in the first state. Further, a specific winning area (V pocket) 7 is provided at a predetermined position in the winning opening 5, and a pachinko ball that has won the specific winning area 7 is detected by the specific winning ball detector 8. After the variable display device 3 has a specific display mode and a big hit state occurs and the variable winning ball device 4 is in the first state, a predetermined number (for example, 10) of pachinko balls to the variable winning ball device 4 are displayed. The variable winning ball device 4 is achieved when the winning condition or the predetermined period (for example, 30 seconds), whichever comes first, is satisfied.
Is the second state. When a pachinko ball that has entered the variable winning ball apparatus 11 in the first state wins the specific winning area 7 and is detected by the specific winning ball detector 8, the first state of the time is After the completion, the variable winning ball device 4 is repeatedly and continuously controlled to the first state. The upper limit of the repetition continuation control is set to 16 times, for example. By setting the variable winning ball device 4 to the first state, a large amount of pachinko balls can be won in a relatively short time, and a predetermined game value can be given. Then, the prize balls are paid out into the ball storage tray 54 based on the occurrence of the prize balls, and the surplus balls that are full of the ball storage tray 54 and cannot be stored any more are provided below. It is discharged into the surplus ball storage tray 55. In the present embodiment, the variable prize ball device is set to the first state for the predetermined period as an example of the game value addition, but a predetermined number of prize balls are directly paid out, or a card-type game machine (prize ball payout) is given. Instead of the above, a predetermined score may be directly given.

If a pachinko ball wins again at the start winning holes 10a, 10b, 10c while the variable display device 3 is variably displaying the start winning prize, the variable display of the variable display device 3 is stored. When the variable display device 3 is stopped and the variable display is enabled again, the variable display device 3 is variably displayed again based on the start winning award memory. The upper limit value of the starting winning prize memory is set to “4”, for example, and the number of starting winning prize memories at the present time is displayed by the starting memory indicator 16.

In the present embodiment, the variable display device 3 shows a variable display of a plurality of types of symbols by using a CRT, but in addition, for example, a liquid crystal display, plasma, LED, fluorescent display tube, or the like. Various types are included, such as those that perform segment display or dot matrix display using electroluminescence, those that perform screen display, rotary drum type variable display devices, and the like. In addition, the second state of the variable winning ball device 4 may be a state in which a ball can be won but it is difficult to win.

In FIG. 1, 17 is a rail decoration lamp, 18 is a side lamp, 20 is a frame lamp, and 22 is a decoration LED, each of which lights up or blinks in a game state. Reference numeral 12 is a 10-count display device for displaying the number of winning prize balls in the variable winning ball device 4. Reference numeral 21 denotes a speaker, which produces a sound effect when a big hit occurs.

2A and 2B are views for explaining a change in the display state of the variable display device. FIG. 2A is a screen view showing a display screen of the variable display device, and FIG. 2B is a variable display device. It is a figure which shows the change of the display state in one variable display part.

As shown in FIG. 2A, on the display screen 70 of the variable display device 3, symbol display portions 71A to 71G, which are examples of seven variable display portions, are displayed. All of those symbol display portions 71A to 71G start variable all at once. And after the predetermined basic time has passed,
71A, 71B and 71C simultaneously variably stop, and then 71
D stops, then 71E stops, then 71F stops, and finally 71G stops. Each symbol display section 7
In 1A to 71G, the symbol "7", the fruit symbol such as grapes, and the deviating symbol consisting of a star are variably displayed. The symbol display portions 71A, 71B, 71C have one "7" symbol and 2
A total of 4 consisting of one fruit design and one outlier design
Individual symbols are variably displayed. Symbol display portions 71D, 71
In E and 71F, a total of 25 symbols including one "7" symbol, 14 fruit symbols, and 10 outlier symbols are variably displayed. In the symbol display portion 71G, one "7"
A total of 27 symbols consisting of the symbol, one fruit symbol and 25 outlier symbols are variably displayed. Then, all the symbol display portions 71A to 71G are variably stopped,
When "7" is displayed on four or more symbol display parts, or when all variable display parts 71A to 71G display a fruit pattern, a combination of specific display modes results in the jackpot state. . In this example,
When four or more "7" appear, the same game value can be given regardless of the number, but the value may be different depending on the number of "7" appearing. For example, when five or more "7" appear, the probability that a big hit will occur as a result of variable display of the variable display device thereafter is improved, and the probability is improved by satisfying a predetermined ending condition. The high probability state may be terminated and the normal probability may be restored. In that case, if "7" appears five times, it is set to the high-probability state only once, if six appears, it is set to the high-probability state only three times, and if seven appears, it is set to the high-probability state five times. May be. Alternatively, when "7" appears five times, the probability of jackpot occurrence is increased to 5 times, and when six appears, it is 10 times higher, and when seven appears, 20 times higher probability state. You may Also,
Depending on the number of appearances of "7", the upper limit of the number of winning prizes in one opening and the upper limit of the number of continuations in one big hit are made different (for example, the upper limit is increased as the number of appearances is increased). Good.

72A, 72B, 72C of FIG.
72G is a mark display frame, which is for making the player easy to understand by enclosing the symbol display portion in which four "7" appear in a frame.

Each symbol display section 7 at the time of reach
The variable display state according to 1 is shown in FIG. For example, in the state where the outlier symbol is displayed by the symbol display unit 71, the next symbol display area 7 for displaying the symbol to be displayed next from the central portion of the symbol display unit 71.
3 is gradually enlarged, and the next symbol display area 73 is enlarged so that the entire symbol "7" to be displayed next is gradually displayed, and the next symbol display area 73 is spread over the entire symbol display portion 71.

When a plurality of symbol display portions are variable-stop-controlled with different stop times, a plurality of "7" s are displayed by the plurality of symbol display portions that have already been variably stopped, or six. The case where all the fruit designs are displayed at the stage when the design display section of is stopped is called a so-called reach state. In this reach state, the speed of the variable display of the symbol display unit, which is stopped and controlled next, becomes slow. Then, there are two types of ways in which a particular display mode is established. Figure 2
As shown in (B) of, for example, three "7" are displayed by the symbol display unit that has already been variably stopped, and when the symbol display unit 71 to be stopped next displays "7". When stopping (when stopping before the dashed arrow),
At the stage where "7" is displayed, the next symbol display area 73 for displaying the off symbol which is the next symbol is gradually expanded without stopping at the stage where the next symbol is expanded to a certain extent. There is a case where the symbol display area 73 is gradually reduced and finally "7" is stopped and displayed. In these two cases, they are selected and displayed in accordance with a random number value created by the microcomputer 80 described later, and each of them is selected and displayed with a probability of 1/2.

In the present embodiment, the variable display device having seven variable display portions is shown, but the number of variable display portions is not limited to the embodiment, and a specific display is also possible. The number of variable display portions as modes is not limited to four or more in the embodiment, and may be one if the number is smaller than the total number of variable display portions.

FIG. 3 is a diagram for explaining changes in the display state of the symbol display portion 70 of the variable display device. First (A)
As shown in FIG. 7, the symbol display portions 71A, 7 which are already stopped
When both 1B and 71C stop display "7", it is the reach state described above, and in that case, the symbol display portions 71A, 71B, 7 in which the reach state is established.
1C and the symbol display portion 71A which is stopped and controlled next are surrounded by the mark display frames 72A, 72B, 72C and 72D and displayed so that the player can easily understand. In addition, since the symbol display unit in the variable display normally switches and displays each symbol at a high speed, the symbol display units 71E and 71 in (A) are displayed.
It is not possible to clearly see the transition of the symbols like F and 71G. However, as described above, since the speed of the variable display of the variable display portion 71D that is next stop-controlled when the reach state is established becomes slow and the variable display method changes from the switching display to the method of FIG. 2B. The next symbol display area 73D of the variable display portion 71D controlled to be stopped next becomes a state in which the player can clearly see the state in which the next symbol display area 73D is expanding.

Then, as shown in (B), if the symbol display portion 71D is not "7" when stopped, the variable display speed of the symbol display portion 71E controlled to be stopped next becomes slow. The player can visually recognize the state where the next symbol display area 73E is expanding, and the symbol display section 71E is frame-displayed by the mark display frame 72E.

Next, as shown in (C), the symbol display portion 71
When E is stopped by the disengaged symbol, the speed of the variable display of the symbol display portion 71F, which is controlled to be stopped next, becomes slower, and the player can visually recognize the state in which the next symbol display area 73F expands. At the same time, it is framed by the mark display frame 72F.

Next, as shown in (D), the symbol display portion 71
When F stops with the disengaged symbol, the speed of the variable display of the symbol display portion 71G, which is controlled to be stopped next, becomes slow and the player can visually recognize the state where the next symbol display area 73G expands. At the same time, it is framed by the mark display frame 72G.

Next, as shown in (E), the symbol display portion 71
When G stops at "7", the combination of the specific display modes is established, and the symbol display portions 71A, 71B, 71C, 71 in which the specific display mode combinations are established.
G is framed by the mark display frame. As described above, when the number of specific display modes is equal to or more than the predetermined number, a big hit occurs regardless of where the specific display mode is established. Therefore, it is easy for the player to understand the condition for generating a big hit. Further, in the past, if the specific display form is not complete on the predetermined hit line, even if any number of "7" symbols are displayed, it will be missed and the player will be dissatisfied, but the book In the case of the embodiment, such deficiency can be eliminated.
