Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine,
For example, the present invention relates to a gaming machine in which a jackpot probability changes depending on a game state, for example, a probability that a special symbol becomes a jackpot symbol varies depending on a mode of a normal symbol, and there is a profit difference between the ordinary symbols to enhance the interest. 2. Description of the Related Art In a conventional game machine such as a pachinko machine, for example, in the case of a single-type pachinko machine, when a special jackpot symbol is obtained, a special jackpot is opened as a jackpot. Then, when a special symbol is obtained from the jackpot symbols, the probability of obtaining the jackpot symbol in the special symbol, that is, the jackpot probability shifts to a high probability, and the time shortening function is activated in the fluctuation of the ordinary symbol and the special symbol. In addition, the time for opening the first-type starting port is extended. [0003] That is, in the conventional pachinko machine classified as one kind, when a game ball wins a large winning opening, for example, 15 game balls can be obtained for each winning ball, and the other winning openings are won. When you do, for example, five game balls can be acquired, and when the game ball passes through the left gate or the right gate, the normal symbol displayed on the normal symbol display of the ordinary symbol display device is, for example, It starts to fluctuate (alternate lighting of red and green) in two symbols of red symbol and green symbol, and the symbol variation stops for about 30 seconds at low probability and about 6 seconds at high probability, and usually The pattern is determined. Then, when the determined normal symbol displays a specific symbol (for example, a red symbol), it is a hit. When the display of the specific symbol is activated, the winning opening relating to the ordinary electric accessory, that is, the first-type starting port is set at a low probability. In this case, an operation such as opening is performed once for about 0.5 seconds, and for about 2 seconds when the probability is high. In addition, the detection of the game ball at the first type starting port (that is, winning) activates a plurality of left special symbols, middle special symbols, and right special symbols displayed on the special symbol display of the special symbol display device. Start changing with the symbol. Then, when a predetermined time elapses after the special symbol starts to change, the symbol change stops, and the special symbol is determined. And when the confirmed special symbol displays a predetermined combination, it will be a big hit,
When the display of the symbol combination is activated, the special winning opening is opened, for example, for about 30 seconds. Further, when the special symbol is a big hit in the specific symbol, a period from the time when the operation of the condition device by the big hit is finished to the time when the specific symbol display device is operated 10,000 times, for example (this period is the condition by the next big hit). It ends with the operation of the device), the probability of winning a jackpot shifts to a high probability, and the time shortening function is activated in the fluctuation of ordinary symbols and special symbols, extending the time of opening the first type start port etc. It is. [0004] The conventional type 1 pachinko machine is in a high probability state from the end of the operation of the condition device due to the jackpot until the condition device is activated by the next big hit, and is otherwise low. Like the probability state, the probability of obtaining a special symbol in a special symbol, that is, the special jackpot probability is fixed to one of a high probability and a low probability depending on whether or not it is a big hit. Then, at the time of the big hit, the game conditions are changed so as to be in a state advantageous to the player, such as opening of the special winning opening, shortening of the symbol change time, and extension of the time of opening the first type starting opening. However, since all of the changes in the game conditions including the change in the probability are such that the winning of the game ball to the type 1 starting port is the only trigger, the game tends to be monotonous. The profit margin is hard to come out and the taste is not enough. That is, in a conventional gaming machine such as a type 1 pachinko machine, it is important to match a special symbol and to win a type 1 starting port as a trigger for the operation of the special symbol. When the symbol becomes a specific symbol, a winning opening (first-type starting opening) related to the ordinary electric accessory is opened for a predetermined time when the symbol is activated, and, for example, five game balls can be obtained as prize balls. However, it is not more than that, and the time when the first-type starting port is opened as a hit is about 0.5 seconds during a normal game that is not a big hit,
Since the probability of winning in the seed opening is low, during the normal game, the normal symbol displayed by the ordinary symbol display and the first type opening that opens when the ordinary symbol becomes a hit symbol are noticed. There is hardly any thing, and the eyes of the player concentrate on only the symbol matching of the special symbol, and the game has little change. In particular, in recent gaming machines, the symbol display is usually small as neglected, and it is difficult to understand where on the game board. [0006] The present invention has been made in view of the above-mentioned problems, and in a gaming machine in which a gaming condition changes to a condition highly advantageous to a player when a special symbol is obtained in a special symbol, a profit difference due to a normal symbol is obtained. It is an object of the present invention to increase the value of the symbol, thereby increasing the importance of the ordinary symbol, and enabling a variety of highly interesting games to be played. [0007] In the present invention, by changing the probability of a jackpot according to the mode of a normal symbol and providing a profit difference, it is possible to play a variety of highly interesting games. It was done. In the gaming machine according to the first aspect of the invention, the detection of the game medium in the predetermined normal symbol start area starts the symbol change, and the symbol change is stopped and determined after a predetermined time has elapsed. A normal symbol display device that displays a stop symbol, and starts a symbol change triggered by the detection of the game medium in a predetermined special symbol start area, and stops the symbol change after a lapse of a predetermined time to determine a stop symbol that has been determined. The special symbol display device to be displayed, and the mode of the stop symbol after the symbol change displayed by the ordinary symbol display device, the special symbol start area is opened and closed so as to be switched between an expanded state and a non-expanded state,
The left small feather as a starting area changing means is set to a non-expanded state when the pattern is out of alignment, and to be in an expanded state for a predetermined time when the pattern is a hit symbol.
The game condition is changed from the normal game condition, which is relatively less advantageous to the player, based on the root and the right small blade, and the symbol mode after the symbol change displayed by the special symbol display device becomes a predetermined mode. in high gaming machine comprising a gaming condition change means for changing the special game condition, they left small in unexpanded state of the special symbol start area left small wing and right small blade is closed as the starting area variation means Feather
A first start detecting switch for detecting a game medium passing through the special symbol starting area through a space between the first symbol and the right small blade, and expanding / non-expanding the special symbol starting area by opening / closing the starting area varying means. And a second start detection switch for detecting a game medium passing through the special symbol start area regardless of whether the game medium is detected only by the second start detection switch. And the second
It is characterized in that the probability that the display mode after the symbol change of the special symbol display device becomes the predetermined mode becomes higher than that when both are detected by the start detection switch. [0009] In this case, normal symbol display device starts to symbol variation detection at normal symbol start region as a working trigger,
The symbol variation display the stop symbols which confirm stopped after a predetermined time has elapsed, the normal symbol display device for displaying special symbol start region is enlarged or reduced by embodiments of the stop symbols, special symbol start region when per symbol Expands. In this way
When the symbol of the normal symbol display device becomes a hit symbol, the special symbol starting area is enlarged, so that the probability of detection in the special symbol starting area is increased. In other words, the probability of detecting a game medium that triggers a symbol change for a big hit varies depending on the mode of the symbol displayed by the ordinary symbol display device . DETAILED DESCRIPTION OF THE INVENTION Hereinafter, will be explained based on the embodiment of the present invention with reference to the drawings. FIG . 1 is a plan view of a gaming machine showing an example of the embodiment. In FIG. 1, reference numeral 1 denotes a game board, on which a game area 3 is defined by rails 2.
A special symbol display device 4 is arranged substantially at the center of the game area 3, a normal symbol display device 5 is arranged adjacent to the upper center of the special symbol display device 4, and further above the natural symbol prize opening 6. Is arranged below the special symbol display device 4, and a normal electric accessory 8 having a first-type starting port 7 (corresponding to a predetermined special symbol starting area), which is a winning opening related to the ordinary electric accessory. A special electric accessory 10 having a special winning opening 9 is disposed immediately below. A left gate 11 and a right gate 12 are provided on the left and right sides of the special symbol display device 4.
(Corresponding to a predetermined normal symbol starting area) is arranged, and a left sleeve winning opening 13 and a right sleeve winning opening 14 are arranged on the left and right sides of the ordinary electric accessory 8 having the first type starting opening 7. , The lower left winning opening on the left and right sides of the special motorized character 10 with the big winning opening 9
15 and a lower right winning opening 16 are arranged. The ordinary electric accessory 8 is driven by an ordinary electric accessory solenoid (not shown) at the opening position of the first type starting port 7 to switch the first type starting port 7 between the expanded state and the non-expanded state. Left and right small blades that open and close horizontally
18 (corresponding to a starting area varying means for enlarging or reducing the special symbol starting area). Above the first-type starting port 7, the direct inflow of game balls into the first-type starting port 7 is blocked, and the small left and right small blades 17, 18 are closed in a non-expanded state. A first start detection switch 19 for detecting a game ball flowing into the first type starting port 7 through the space between the blades 17 and 18 is provided. A second start detection switch 20 for detecting a game ball passing through the first type start port 7 regardless of the opening state is provided. The special electric accessory 10 is opened and closed left and right at the opening position of the special winning opening 9 so as to be driven by a special winning solenoid (not shown) to switch the special winning opening 7 between an opened state and a non-opened state. A large blade 21 and a right large blade 22 are provided. The ordinary symbol display device 5 has three red and green LED lamps arranged in a horizontal line. Those L
The ED lamp is red on two sides and green on the center. The special symbol display device 4 has three symbol display areas of a right symbol display area, a left symbol display area, and a middle symbol display area, and each of the three areas has ten types of numbers from 0 to 9. Display the special symbol of. In this gaming machine, for example, when the inflow (winning) of a game ball to the large winning opening 9 is detected, for example, 15 gaming balls can be obtained for one winning ball, and the other winning holes (the first winning ball) can be obtained. 1
(Including the seed starting port 7), for example, five game balls can be obtained. In addition, the game ball is left gate 11 or right gate
When passing through 12, the normal symbol displayed by the normal symbol display device 5 starts to fluctuate (alternately illuminating red and green) in two symbols of a red symbol and a green symbol with the passage as an operation trigger, and a predetermined stop time. After a lapse of about 29.0 seconds at the time of the low probability and about 6.5 seconds at the time of the high probability, the fluctuation of the symbol is stopped, and the symbol is usually determined. When the determined ordinary symbol displays a red symbol, it is a hit, and the opening operation of the first-type starting port 7 is performed once with the display of the combination of the symbols being activated. As a result, the left small blade 17 and the right small blade 18 of the ordinary electric accessory 8 are opened, and the first type starting port 7 is in the expanded state. The opening operation of the first-type starting port 7 is completed in 0.2 seconds at a low probability described later and 2.0 seconds at a high probability described later,
Upon completion, the left and right small blades 17 and 18 close, and the first-type starting port 7 returns to the non-expanded state. When a game ball continues to pass through the left gate 11 or the right gate 12, up to four balls become operation-holding balls, and when a symbol is normally displayed, a symbol is displayed. When the winning symbol is displayed, the change of the ordinary symbol is started again by the operation-holding ball after the opening operation of the first-type opening 7 is completed. [0020] The inflow to the first one starting port 7 of the game ball (winning)
Is detected, the special symbols (left special symbol, middle special symbol, right special symbol) in the left symbol display area, the middle symbol display area, and the right symbol display area of the special symbol display device 4 are all triggered by the operation. Start changing with 10 symbols. Then, after a predetermined stop time has elapsed since the start of the special symbols, the symbol change stops (left special symbol, middle special symbol,
Stops at the same time as the right special symbol), and the special symbol is determined. When the determined special symbol indicates a predetermined combination, the winning is a big hit, and the opening of the special winning opening 9 is triggered by the display of the combination of the symbols.
Is done many times. As a result, the left large blade 21 and the right large blade 22 of the special electric accessory 10 are opened, and the special winning opening 9 is in an expanded state.
The opening operation of the special winning opening 9 is performed, for example, for 29.5 seconds, and when completed, the left and right large blades 21 and 22 are closed, and the special winning opening 9 returns to the non-expanded state. This operation is repeated once or a predetermined number of times. [0022] The game ball, which was finished in the first one start hole 7, up to four is the working pending sphere, if the special symbols displayed a pattern out, after the stop time of the symbol variation has elapsed, also,
When the big hit symbol is displayed, the change of the special symbol is started again by the operation-holding ball after the opening operation of the special winning opening 9 is completed. [0023] Whether a particular symbol becomes a predetermined combination, determined by the lottery of random numbers. That is, the determined special symbol (stop symbol) after the symbol change of the special symbol display device 4 triggered by the winning of the game ball to the first kind starting port 7 (special symbol starting area) is a predetermined combination (predetermined mode). ) Is defined by a special symbol random number (big hit random number) which is randomly selected when a game ball enters the first type starting port 7. In this example, as the special symbol random number, for example, a random number having a random number value of 0 to 630 is prepared, and this one random number is used for the ordinary symbol (stop symbol) displayed on the ordinary symbol display device 5. It is used as a plurality of random numbers having different probabilities depending on the mode . [0025] Thus common to change the jackpot probability by aspects of the design, the first starting detection switch 19 as described above as a starting detection switch second start detection switch
There are 20 of them. When the normal symbol is a lost symbol, the left and right small blades 17 and 18 of the normal electric accessory 8 are closed, and the first-type starting port 7 is in a non-expanded state. At this time, the game ball that wins the first kind start port 7 is detected by the first start detection switch 19, and is also detected by the second start detection switch 20. Also,
When the normal symbol is a hit symbol, the small blades 17 and 18 on the left and right of the ordinary electric accessory 8 are opened, and the first-type starting port 7 is in an expanded state. At this time, the game ball which wins the first kind starting port 7 is the first kind.
It is not detected by the start detection switch 19, but is detected only by the second start detection switch 20. Normal pattern hits
In the case of, a random number with a high probability (1 / 78.875) is used. In addition, when the normal symbol is a missing symbol , a low probability (1
/315.5) is used to perform a jackpot lottery. [0027] In this manner, in one special symbol random number itself, in addition to the method of varying the probability by changing the number of jackpot random values, originally may be prepared two different random probability . The invention has been described by way of example an embodiment,
The present invention is not limited to these examples, and can be implemented by appropriately changing aspects within the technical idea of the invention. Further, although the above-described respective examples have been described with respect to a pachinko machine, the present invention is not limited to this, and it is needless to say that the present invention can be applied to other gaming machines such as a slot machine and an arrangement ball. As is apparent from the above description, according to the present invention, the symbol display device for displaying a special symbol or the like has a predetermined pattern, and the probability of a big hit is a normal symbol or the like. Is changed depending on the symbol form of the other symbol display device, and a difference in profits is generated for the player, so that the game is rich in change and the taste is improved.
