This display unit is configured with a plurality of rows of symbol variation screens (there is also a background screen), and is configured to notify a hit or miss in a line when the symbols are stopped.

In the notification based on the symbol variation, the scroll speed of the symbol variation is changed as a reach pattern in order to give the player a sense of expectation. For example, if the speed of scrolling decreases when approaching a winning symbol, the player expects that the winning symbol will stop and concentrates on symbol variation display. It should be noted that there are a plurality of such reach patterns, which are selected according to a predetermined program.

[0005] However, the above-mentioned fluctuation of the scroll speed, when the player is skilled, the pattern is monotonous,
Poor visual change. Further, since the probability of hitting / losing is unknown, the expectation gradually decreases. In addition, because the reach pattern is selected according to a predetermined program, even in the resulting reach pattern, the player can have a sense of expectation until the end, but because of disappointment in the end, some players Some people find this annoying (unpleasant).

In view of the above facts, the present invention makes it possible to carry out symbol variation between players in accordance with the concept of a reach pattern, to maintain the player's expectation of the reach pattern, and to reduce the discomfort felt by the player.

In the main control board 150, a special symbol or a normal symbol is selected by lottery, the display content on the display section 124 is selected based on the lottery result, and an instruction signal is output to the display control board 160. That is, the display control board 160 stores data of different display contents based on a plurality of types of command signals in advance, and selects and starts data based on the command signals.

Here, as shown in FIG. 3, in the display control board 160 in the present embodiment, the display section 124
Is provided with a memory 250 for storing a plurality of types of symbol variation patterns produced in the above.

The symbol variation patterns 252 stored in the memory 250 (in FIG. 3, for convenience, each symbol variation pattern 25
2 is shown in the form of a file icon. ) Are classified into a normal out-of-pattern group 254 and a reach pattern group 256, and the reach pattern group 256
It is classified into a normal reach pattern group 258 and a special reach pattern (non-normal reach) pattern group 260.

When the reach pattern group 256 is shown by specific numbers using a specific gaming machine as an example, it is constituted by ten types of reach patterns. Note that this numerical value is a specific gaming machine, and does not correspond to all gaming machines.

As shown in FIG. 4, when these ten types of reach patterns are PAT1 to PAT10, PAT1 is a normal reach pattern and PAT1 is a normal reach pattern.
2 to PAT10 are special reach patterns. Note that P
AT10 is a special reach pattern (premium reach pattern) among special reach patterns selected only at the time of hitting.

As shown in FIG. 3, the display control board 160
Then, the above-mentioned out-of-pattern group 2 stored in the memory 250
From the 58 and reach pattern group 260, all reach patterns can be selected based on the program specifications predetermined in the CPU 262 (basic specification mode).

Here, in the conventional pachinko machine, only the basic specification mode is used. In the present embodiment, two types of modes are set in addition to the basic specification mode. Can be freely set by the player.

That is, on the front of the pachinko machine 110,
A mode setting device 264 (see FIGS. 1 and 3) is provided. The mode setting device 264 is connected to the display control board 160, and the operation state of the mode setting device 264 corresponds to the mode selection in the display control program. The player can select a desired mode from three types of modes by selecting a mode with the mode setting device 264.

The detailed specification of the mode will be described below, including the basic specification mode. Basic specification mode In this mode, all the patterns stored in the memory are selected as described above. In particular, even when selected from the reach pattern group 256, PAT1 to PAT1
For example, a pattern determined by a random number counter or the like is selected from the PAT 10 as a symbol variation display pattern,
A display effect on the display unit 124 is executed. Classification mode In this mode, when selecting from the reach pattern group 256, if the result of the lottery is out of order, only the normal reach pattern is selected, and only in the case of a hit, the special reach pattern is selected. When this mode is selected, there are many misses and the appearance of normal reach patterns as opportunities, but since normal reach is short in time, it is not necessary to see useless effects, thereby reducing discomfort. In addition, when other special reach patterns appear, there is no departure, so that the pattern variation pattern is seen on the premise that it exceeds the expectation and hits, resulting in a sense of superiority. Sorting mode is a mode that is advantageous for players who want to enjoy the design change of special reach patterns other than the normal reach pattern or to see the design change of many special reach patterns for research quickly rather than the game itself.

Only a specific reach pattern may be selectable.

By preparing the above three types of modes, it is possible for most players to maintain an expectation and produce an effect that does not cause discomfort.

The operation of this embodiment will be described below.

First, when the pachinko ball is fired, it is guided by the rail 112 and the nail 116 of the gauge portion 114 or the windmill 1
While abutting on 18 etc., it falls while moving unpredictably. Here, when a prize hole 120 is won, a predetermined number of pachinko balls are paid out (prize balls). Further, when the normal symbol starting winning port 130 is won, the normal symbol winning sensor 170 detects this.

By this detection, the main control board 150
Ordinary symbol lottery starts. That is, a number from 0 to 9 is randomly selected with a predetermined probability using a random number counter.
If the lottery results in a loss, there is no change in the game state. On the other hand, if the lottery results in a win (for example, a winning number of 7 is drawn), the main control board 150 opens the electric tulip 134 provided in the special symbol starting winning opening 126 so as to open. Power is supplied to the solenoid 174. As a result, a high probability state in which the pachinko ball easily enters the special symbol starting winning opening can be achieved.

When a pachinko ball wins in the special symbol start winning opening 126, a jackpot lottery is started on the main control board 150 with a predetermined establishment using a random number counter. When the winning / losing is determined as a result of the jackpot lottery, an effect pattern (symbol variation pattern) prepared in advance is selected (a random number counter may be selected).
Then, a command signal is transmitted to a control board related to the effect including the display control board 160.

The display control board 160 displays a symbol variation pattern on the display unit 124 via the display driver 166 based on the received command signal. In this symbol variation pattern, there are various effects such as hitting through reach, out-of-reach, and out-of-reach, and the player can wait for the lottery result with a sense of expectation.

Here, in the case of a hit, by opening the special winning opening 128 for a predetermined time and a predetermined number of times, the probability of winning of the pachinko ball becomes extremely large, and a state advantageous to the player can be achieved. it can.

If a pachinko ball wins in the special symbol starting winning opening 126 during the symbol variation display, the lottery is performed at that time, but the symbol variation display currently in progress waits until the symbol variation display is completed. . This is the hold lamp 200
Is turned on to notify the player.

In such display control, conventionally, in the case of hitting or departure through the reach, normally, as shown in FIG. 4, the left symbol stops first, and then the center symbol stops. The stopped symbol became the same symbol, and finally, by lowering the scroll speed until the right symbol stopped, or by letting a specific character appear, the reliability that would be a hit in this reach was expressed , For skilled players,
Even without looking at the results, they could understand them, lowering their expectations.

On the other hand, in the present embodiment, the mode setting device 264 is provided at a position where the player can operate, that is, at the front of the pachinko machine 110, and the mode setting device 264 controls the appearance state of the reach pattern ( Mode) can be changed.

Hereinafter, the reach pattern selection control will be described with reference to the flowchart of FIG.

In step 300, it is determined whether or not the pachinko ball has won the special start winning opening 126 (actually, it is detected by a sensor). Is executed. This lottery is a lottery using a random number counter on the main control board 150.

In the next step 304, it is determined whether the result of the lottery is a hit or a miss, and then in step 306,
On the basis of this determination result, the pattern group (the off-pattern group 2
54 or reach pattern group 256).

In step 308, step 3
As a result of the selection in step 06, if it is determined that the out-of-pattern group 254 has been selected, the out-of-off pattern is determined and the reach pattern is not executed. , To 312.

If it is determined in step 308 that the reach pattern group has been selected as a result of the selection in step 306, the operation state of the mode setting device 264 (by the operation of the player) is read in step 314. It is. In step 316, based on the mode read in step 314, the reach pattern (PA
T1 to PAT10) are selected, and the routine goes to Step 312.

In this embodiment, three modes can be selectively set, and each mode has the following specifications.

That is, in the basic specification mode, the memory 25
This is a specification in which all reach patterns stored in 0 are randomly selected (according to a program stored in advance). .

The classification mode is the reach pattern group 2
When the selection is made from 56, only the normal reach pattern is selected when the result of the lottery is out, and the special reach pattern is selected only in the case of a hit.

Further, in the selection mode, a player who wants to enjoy the design change of the special reach pattern other than the normal reach pattern rather than the game itself, or wants to see the design change of many special reach patterns quickly for research. This is an advantageous specification.

At step 312, display control of the symbol variation pattern by the display unit 124 is executed.

According to the present embodiment, since the appearance state of the reach pattern can be changed by the player's intention, the player can play a game in an appearance state that is suitable for himself / herself.

That is, although the appearance of the conventional reach pattern is random (program specification), it does not always meet the individual requirements of all players. However, in the present embodiment, the mode setting unit 264 is set in a state where it can be operated by the player, and the mode can be changed by the player himself who executes the game. Can be. For this reason, it is possible to maintain the expectation of the reach pattern for a normal (eg, beginner) player, and to eliminate the discomfort that a skilled player or the like would be after a long reach pattern. can do.

That is, each of the three modes is classified according to its purpose. That is, the basic specification mode is the appearance of the reach pattern according to the normal program, and all the reach patterns 25 stored in the memory 250 are stored.
2 can appear all over, and the conventional merits can be maintained. Thereby, the player can enjoy the design fluctuation with a sense of expectation.

In the classification mode, the result of hitting / losing can be easily understood, so that the merits can be expanded especially for a skilled player. As a result, it is possible to prevent the player from feeling uncomfortable as a result of the long reach.

Further, the selection mode can respond to a demand that a player who wants to appreciate a symbol change in addition to a game does not want a simple symbol change pattern to appear. In addition, it is possible to easily study the relationship between the pattern fluctuation and the hit / miss, and it can be a training for beginners.

In this embodiment, three types of modes are prepared. However, the types of modes are not limited to these modes.
Types or four or more types may be used. Also, the contents of each mode are not limited to the above, for example,
An almighty mode or the like may be provided so that the player can freely select the symbol variation pattern 252. Further, a short time mode and a normal (long) time mode may be prepared for the same symbol variation pattern.
In this case, the short-time mode may be a simple fast-forward of the normal time mode or a thinned-out reproduction.

[0081]

As described above, according to the present invention, it is possible to execute a symbol change between players in accordance with the concept of a reach pattern, to maintain a player's expectation of the reach pattern, and to make the player feel uncomfortable. Can be eliminated.
