DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a plurality of variable symbol displays, such as a slot machine and a pachinko gaming machine, capable of displaying a plurality of types of symbols by changing them, and a variable display of each variable symbol display. The present invention relates to a variable symbol display game machine in which a winning or losing is determined by a combination of symbols arranged on a winning line crossing each display when the game is stopped.

[0002]

2. Description of the Related Art A typical conventional slot machine is provided with three reels each having a predetermined number of symbols arranged on an outer peripheral surface. When the player performs a game start operation, the reels rotate at the same time, and the symbols of each reel are cyclically displayed in the symbol display window on the front. On the symbol display window, five winning lines, upper, middle, lower, and diagonal, are set. When each reel is sequentially stopped in response to a stop operation by the player, each reel is displayed on each of the winning lines. Are displayed in an aligned state.

When a predetermined combination of symbols is formed on the activated pay line when all reels are stopped, a winning is achieved, and the player receives a predetermined number of medals according to the type of winning.

Further, in recent slot machines, a lottery is performed in the control unit in accordance with the start of each reel, and in accordance with the lottery, each reel is stopped so that a predetermined symbol is drawn on a pay line. Control behavior.
In particular, when the lottery is a "big hit", each reel is controlled so as to draw a specific symbol such as "7" on the pay line and stop. When the combination is established, the process shifts to a “bonus game” in which winnings appear with a high probability.

[0005] More recently, with the end of the bonus game, a lottery is performed again, and when the lottery is won, a model that sets a game mode called "challenge time" for competing for the skill of the player has appeared. ing. In this “challenge time”, the pull-in control for at least one reel is released, and the reel is stopped according to the timing of the stop operation of the player. Therefore, the more skilled a player is, the more the player can aim for a winning symbol and receive more medals.

[0006]

However, since the conventional "challenge time" is set irrespective of the skill of the player based on the lottery in the control unit, the player who wants to shift to the "challenge time" somehow However, there is a problem that the game is lacking in interest in the game.

[0007] The present invention has been made in view of the above-mentioned problems, and allows a player to intervene in the setting of a control mode in which a special game such as a challenge time can be executed, thereby allowing the player to intervene. It is an object of the present invention to provide a symbol variable display game machine which has a pleasure of allocating a special game by itself and has improved game characteristics.

[0008]

According to the first aspect of the present invention, there are provided a plurality of variable symbol displays for changing and displaying a plurality of symbols, and each symbol variable display is started and then stopped sequentially. At least one variable object can be displayed on a variable symbol display game machine in which a winning or losing is determined by a combination of symbols arranged on a winning line crossing each symbol variable display. A variable display for a sub game, lottery means for determining a variable display speed of the sub game variable display, and a predetermined condition established by a game using each symbol variable display. After starting the variable display for the sub game, the variable display is displayed at the speed determined by the lottery means, and then the variable display is stopped according to the stop operation of the player. A beam execution means, wherein when a predetermined game result in the subgame is obtained, thereby and a special game setting means for setting viable special game by each symbol of the variable display device.

According to the second aspect of the present invention, as the variable display for the sub game, a display for moving and displaying a predetermined object is used, and the special game setting means is set when the sub game is executed. The special game is set to be executable in response to the stop of the object at a predetermined position by a player's stop operation.

According to the third aspect of the present invention, a variable symbol display for a normal game is used as the variable display for the sub game.

[0011]

According to the first aspect of the present invention, a special game can be executed based on the result of a sub game in which a predetermined object is changed and then stopped by a player's stop operation. The skill of the player can be interposed in the setting of. However, since the variable display speed of the variable display for the secondary game varies depending on the lottery result, whether or not a special game can be executed depends not only on the skill of the player but also on the factor of luck. Become.

According to the second aspect of the present invention, as the sub game, a game is executed in which a target to be moved and displayed is aimed at a predetermined position. If the aiming is successful, a special game can be executed.

According to the third aspect of the present invention, when a predetermined condition is satisfied in a normal game using each symbol variable display,
A sub game using at least one symbol variable display is started.

The term “medal insertion” used in the following description includes both concepts of direct medal insertion from the medal insertion slot 16 and consumption of stored medals.

Further, the slot machine 1 of this embodiment
By operating the start lever 14, each of the reels 8a, 8b, 8c
Immediately after is started, a lottery is performed in the control unit, and a combination of symbols to be established on a winning line is determined according to the result of the lottery (hereinafter, this lottery is referred to as a "lottery for determining a prize"). . And the stop button switch 15a,
Each time 15b, 15c is operated, the corresponding reel 8
For “a”, “8b”, and “8c”, “pull-in control” is performed in which the target symbol is pulled until the target symbol moves on the pay line and then stopped. In particular, when the lottery for the winning determination is "big hit", the pull-in control is performed such that the symbol combination of the number "7" is established on the winning line, and the symbol combination of the "7" is further established. Accordingly, a bonus game having a high winning probability is executed a plurality of times.

However, the above-mentioned pull-in control needs to be performed within the range of the number of frames specified by the law, and if it is impossible to pull in the symbols within this number of frames, the target is not displayed on the winning line. Symbol must be stopped. Laws and regulations also prohibit the simultaneous establishment of multiple types of winnings, so if another winning is simultaneously established by pulling in the target symbol, remove the symbol from the target pull-in position and stop the reel. There must be.
Therefore, depending on the stop operation position of the player, a situation occurs in which the winning can not be won even though the lottery has been won.

However, even though the lottery is determined to be a big hit, that is, a special prize is established,
If the special winning is not established, the result of the lottery is carried over as a "winning flag", and thereafter, a control for drawing the symbol "7" onto the winning line is performed until the special winning is established. .

Note that recent slot machines have a structure in which a plurality of types of special prizes such as a "big bonus" and a "regular bonus" appear. In this embodiment, for the sake of simplicity, "7" is used. It is assumed that only one kind of special prize by the symbol combination of "" appears.

Further, in the slot machine 1 of this embodiment, when the bonus game accompanying the special prize ends,
A sub-game using the shift display 30 is performed, and when the sub-game becomes a "hit", the game shifts to a "challenge time" for measuring the skill of the player.

The shift display 30 has a plurality of (eight in the illustrated example) mini lamps 30 on the upper surface of the elongated substrate 29.
a to 30h are arranged, and an opening (not shown) opened at an upper position of the front panel 11 in a state where the length direction is aligned with the arrangement direction of the respective symbol display windows 20a to 20c. ) And fixedly deployed. A wiring pattern (not shown) for driving each mini lamp is formed on the back surface of the board, and is electrically connected to the control board 5.

Each of the miniature lamps 30a to 30h emits light of a predetermined color (for example, red light), and receives a drive signal from a control unit and shifts the lighting and extinguishing operations to shift the color. To realize the shift display of the light emitter. This shift display is stopped by the operation of the stop button switch 15c for stopping the right reel 20c, and the shift display is stopped at the same time as the stop operation is received by the control unit, and the beans that have emitted light at that time are stopped. The light emitting state of the lamp is maintained for several seconds. The switch for stopping the shift display is not limited to the stop button switch 15c, but may be another switch or the start lever 14. Alternatively, a stop button switch dedicated to the sub game may be provided separately.

When the shift display is stopped at any one of the four mini lamps 30c to 30f in the center, a "hit" occurs and the process shifts to a "challenge time". In addition, on the upper surface of the substrate 29, a hit zone 29A colored differently from other portions is set in correspondence with the arrangement positions of the hit mini lamps 30a to 30f.

Further, in this embodiment, prior to starting the shift display, a lottery is performed in the control section to set the speed of the shift display to one of high speed, medium speed and low speed. In the high-speed mode, each of the bean lamps 30a-3
0h is switched on at a time interval of about 100 msec, so that it is almost impossible to aim the luminous body in the hit zone 29A. On the other hand, in the medium speed mode, each of the miniature lamps 30a to 30h is turned on at a time interval of about 500 msec so that a player having a certain skill can aim at the luminous body. In the low-speed mode, the lighting operation of each of the miniature lamps 30a to 30h is switched in units of one second, so that the aiming of the luminous body becomes extremely easy.

In this embodiment, the direction in which the lamps of the shift display 30 are arranged is determined by the symbol display windows 20a and 20a.
It is arranged in accordance with the arrangement direction of b, 20c, but is not limited to this, and a roulette-shaped shift display in which a plurality of miniature lamps are arranged around each symbol display window 20a, 20b, 20c or the like is used. You may. Further, a shift indicator may be constituted by a large number of LEDs instead of the miniature lamp.

In place of the structure in which the luminous body is shifted and displayed, a variable display of a type that variably displays a plurality of types of symbols is provided, and when a specific symbol is stopped and displayed by a player's stop operation, " You may make it shift to "challenge time". In this case, a fourth reel may be provided for the sub game, symbols may be scroll-displayed on the liquid crystal panel 28, or the like. Numerical and character symbols may be displayed in a variable manner.

On the other hand, the reels 8a, 8b,
If any of 8c is provided with a function as a variable display for the sub game, a variable display dedicated to the sub game is not required, and the configuration of the machine can be simplified. In addition, by spinning the reels for the base game at low or medium speed, a game different from the base game can be developed. In addition, since it is not necessarily required to be a single variable display for the sub game,
The sub game may be executed by using two to three reels 8a, 8b, 8c.

FIG. 4 shows an electrical configuration of the slot machine 1. In the figure, reference numeral 34 denotes a control unit composed of a microcomputer, which is a CPU 3 which is a main body of control and calculation.
5. ROM 36 for storing programs and tables for the lottery, RAM 3 for reading and writing data
7, and a random number generator 39. ROM 36
In addition to the tables used in the lottery processing for determining the winning, each of the lottery processing for determining the shift display speed at the time of the sub game and the timing for automatically stopping the shift display (details will be described later). Table is also set.

Various input / output units are connected to the CPU 35 via a bus 33. Based on programs in the ROM 36, while recognizing various input signals, a drive signal is given to an output unit, and a series of operations related to the game are performed. Execute the processing of The input unit includes the start lever 14, the stop button switch 15
a, 15b, 15c, bed button switches 17, 18, 1
9, a settlement switch 22, a changeover switch 23, a medal detection sensor 38 for detecting a medal inserted from the medal insertion slot 16, and the like. The output section includes a reel drive section 40 for driving the stepping motors 9a, 9b, 9c, a medal payout machine 6, a liquid crystal panel 2
8, a hit notification lamp 27, a shift display 30, a stored number display 31, a hit number display 32, and an audio circuit 41 for outputting a sound effect and the like are connected.

The lottery processing for determining the winning, and for determining the shift display speed and the stop timing is performed by sampling the random number output from the random number generator and comparing the sampled value with the lottery table in the ROM 36. Done. Also, when performing the pull-in stop control of the reel,
For each of the reels 8a, 8b, 8c, the rotation positions of the reels are sequentially checked while counting the drive signals given to the corresponding stepping motors 9a, 9b, 9c. 9b, 9
Stop c. However, since each control is publicly known, a detailed description is omitted here.

FIG. 5 shows a control procedure in the slot machine 1 of FIG. Note that “ST” in the figure indicates a processing step. First, at the start of the game, when the player operates the start lever 14 after inserting medals, ST1
Becomes “YES”. CPU35 receives this, check the internal winning flag F _B, if the winning flag F _B is not set, performs the lottery process, further if this drawing is "big hit", the winning flag F _B is set (ST2-5). Note If the winning flag F _B which is set in the previous game are carried over, ST2 becomes "YES", the processing of ST3~5 is skipped.

When the combination of symbols to be formed on the pay line is determined in this way, the CPU 35 simultaneously starts the reels 8a, 8b, 8c in ST6. Thereafter, every time the stop button switches 15a, 15b, 15c are operated, ST7 becomes "YES", and the reels 8a, 8b, 8c to be operated are stopped (ST8).

In ST8, the reel stop operation position and
Based on the result of the lottery process,
The selected symbol is selected and the selected
The reel stops when it moves up.
Specifically, S in FIG._RT-1 to S _RTThe procedure of -9 is executed
You.

[0043] First prize when the flag F _B is set, the symbol of "7" is retracted, if possible, S shown in FIG. 6
_RT -1, S _RT -2 are both "YES", the pull control symbols "7" of the object is executed (S _RT -
3). On the other hand, "7" for pull-in within the specified 4 frames
If the symbol cannot be drawn, or if a general prize other than the special prize is established due to the pull-in of the symbol of "7", the process proceeds from _SRT- 2 to _SRT- 4, and the reel is awarded. Stop with symbols other than "7" drawn on the line.

[0044] A similarly if won regular winning by the lottery, if capable of retraction of winning symbols intended, the operation proceeds to S _RT -7 through S _RT -5,6 , draw the winning symbol, if the retraction is not possible, retraction of the other innocuous symbol in the S _RT -8 is performed. If the lottery is missing, _SRT- 9
Then, a symbol that does not establish a winning is selected as a pull-in target, and the reel is stopped.

Returning to FIG. 5, when all the reels 8a, 8b, 8c are stopped by such a reel stop control, S
T9 becomes "YES", and the CPU 35 checks a combination of symbols formed on the pay line.

If the symbol combination of "7" for a special prize is established on the prize line, ST10 is set to "Y".
ES ”and proceeds to the procedure after ST13. If a general prize is established, ST11 becomes "YES",
In ST12, a payout process of a predetermined number of medals is performed, and the process is completed. If "out", ST1
Both “0” and “11” become “NO”, and the game is over.

When a special winning is established in ST10, the CPU
35 notifies the establishment of the special prize by turning on the hit notification lamp 27 or outputting predetermined message information to the liquid crystal panel 28, and then shifts to the bonus game routine of ST13 to obtain a high probability. To execute a bonus game in which a prize is generated a plurality of times. When the routine is finished, followed by resetting the winning flag F _B at ST14, it starts the control process for a secondary game by the shift indicator 30 thereafter.

First, in ST15, the CPU 35 determines whether the shift display is executed at a high speed, a medium speed, or a low speed by lottery. In a succeeding ST16, the CPU 35 starts the shift display 30 to determine the shift. The shift operation based on the speed is executed. Then, when a signal from the player's stop operation is received, the shift display operation is stopped, and the mini lamp that is lit at that time is held as it is for several seconds (ST18, ST21). However, if the stop operation of the player is not performed even after the predetermined time limit T has elapsed, ST
The process shifts from ST17 to ST19 to determine the timing at which the shift display is stopped by the internal lottery (that is, how long the shift display is stopped). When the determined stop timing comes, the process shifts from ST20 to ST21 to execute the shift display stop process.

When the sub game is completed and the shift display is stopped at any of the positions of the bean lamps 30c to 30f in the hit zone 29A, ST22 becomes "YES", and the process proceeds to the challenge time process of ST23. I do.

In ST23, the CPU 35 determines whether each of the mini lamps 30a to 30h of the shift display 30 and the hit notification lamp 2
After notifying the start of the challenge time by blinking the number 7 or displaying message information on the liquid crystal panel 28, the game in which the pull-in control for at least one of the reels 8a, 8b, 8c is released can be executed. To do. This game is executed until a predetermined number of medals are paid out or a predetermined number of games are executed. When any of the conditions is satisfied, the end of the challenge time is notified, and the normal game is executed. Return to mode.

When a high-speed or medium-speed shift display operation is performed in the sub game, a difference between the stop operation in ST18 and the stop operation timing with respect to the timing at which the shift display passes through the hit zone 29A is detected. The deviation is within a predetermined range (for example, 50 msec).
If not, the shift display may be stopped in the hit zone 29A. Also, in the case where the shift display is automatically stopped with the lapse of the time limit T, if the shift of the stop timing determined by the lottery is small with respect to the timing at which the shift display passes through the hit zone 29A, the hit zone 29A is similarly set. The shift display may be stopped within. However, in this case, it is better to increase the allowable range of the shift than to stop the shift display by the stop operation of the player.

According to the above-described configuration, the player can allocate the challenge time by executing the sub game, so that the player can randomly determine the shift to the challenge time by lottery. hand,
This will increase the player's willingness to challenge the challenge time and entertain the game.

Since the shift display speed in the sub game is determined by the result of the lottery, whether or not the player can shift to the challenge time is determined not only by the skill of the player but also by whether or not "low speed shift display" is achieved in the lottery. Luck of the player, and the player's interest in the sub-game can be increased, and a more interesting game can be developed.

This kind of sub game can be used not only for setting a challenge time but also for setting a game mode called “high-probability role game” in which general prizes frequently occur. In addition, a plurality of types of bonus games are provided, and if a bonus game according to any one of the modes is executed in accordance with the establishment of a special prize, the sub game is executed following the establishment of the special prize, Which bonus game to execute may be determined based on the game result.

Further, here, an example is shown in which the present invention is applied to a slot machine in which the symbol display is stopped by a player's stop operation. However, like a pachinko game machine, the symbol display is automatically displayed. The function of executing the above-mentioned auxiliary game and setting a special game control mode in accordance with the game result can be incorporated in the game machine of the stop type.

[0056]

According to the first aspect of the present invention, a special game can be executed based on the result of the sub game in which the predetermined object is changed and then stopped by the player's stop operation. The willingness to win a special game can be sufficiently increased and the expectation can be raised.
In addition, since the variable display speed at the time of the auxiliary game is variably set by lottery, whether or not a special game can be executed depends on two factors, the skill and luck of the player, and a symbol variable with high game characteristics is provided. A display game machine can be provided.

According to the second aspect of the present invention, a game in which a moving target is shot at a predetermined position is executed as a sub game, so that a special game is allocated according to the skill of the player. Can be presented in an easy-to-understand manner. In addition, by aiming at a moving object, the degree of concentration of the player on the game can be increased, and the degree of excitement can be increased.

According to the third aspect of the present invention, the variable symbol display for the normal game is used as the variable display for the sub game, so that the configuration dedicated to the sub game is not required, and the apparatus configuration can be simplified. Further, a game different from the normal game can be developed by, for example, displaying the variable symbol display at a speed different from that of the normal game.
