Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning cylinder type gaming machine called a pachi-slot.

[0002]

2. Description of the Related Art Generally, a slot machine is a typical spinning machine, but in Japan, a gaming machine called a pachislot similar to a slot machine is known.
In this type of spinning drum type gaming machine, a plurality of spinning drums (usually three) are provided, each of which is composed of a wheel in which a plurality of types of symbols are circularly written on the outer peripheral surface. The wheels are coaxially arranged and are driven to rotate by driving means such as a motor.
After the player inserts a game medal and starts the driving means, the rotation of each wheel is stopped when the player presses the operation part of the stop switch as the stopping means that can individually stop the rotation of each wheel. . Part of the symbols (usually three) provided on each wheel are exposed through a display window that is a display means, and the symbols appearing in the display window when the rotation of the wheels is stopped are lined up in a specific relationship. Occasionally, it is determined that a prize is won, and a game medal can be obtained corresponding to a combination of symbols related to the prize. There is a method of using one symbol for each wheel and a method of using a plurality of symbols (usually three symbols) for each wheel for the determination of winning. For example,
When there are three wheels, there is a method called 1 line that uses one pattern aligned on a straight line for each wheel, and a method that uses three patterns for each wheel includes the axial direction of the wheel. Method called 3 lines using only the symbols lined up in three straight lines, and part 3
In addition to lines, there is a method called 5 lines that uses patterns arranged on two diagonal straight lines. Which of 1 line, 3 lines and 5 lines is used can be selected by the number of game medals to be inserted first.

By the way, in this type of spinning-roller type gaming machine, the number of combinations of symbols relating to winning is defined by the "Rules concerning the recognition of gaming machines and the verification of the type". That is, it is defined that the number of symbol combinations relating to winning exceeds 11/100 and does not exceed 40/100 of the number of all symbol combinations. On the other hand, in the game board (so-called pachinko) that is widely used as a game machine, there are about 100 game balls used per minute,
Currently, the cost per minute is about 400 yen. In addition, the number of games played in one minute is about 14 times in the spinning drum type game machine, and the game used in one minute if only one line game using one game medal per game is performed. The number of medals is 14, but in the above-mentioned 5-line game, 3 game medals are required for each game, and the rotating body type gaming machine is configured so that 3 game medals can be inserted at one time. Therefore, one line of game is rarely played, and most of them use three game medals for one game. As a result, the number of game medals used per minute is 42 (= 3 × 14), and one game medal is currently 20 yen. Therefore, the cost per minute of the rotating drum type gaming machine is 840. It will be about yen. In this way, since there is a large difference in the cost required per unit time between the game board and the rotating drum type game machine, in order to reduce this difference, the above rules require re-play rules in addition to the above rules. is there. That is, according to the above rule, "re-play is the next game when a specific symbol combination (excluding the symbol combination relating to winning a prize) is displayed as a result of one game,
It refers to something that can be played without inserting a game medal. The replay is defined separately from winning. However, the re-play is substantially equivalent to a prize in which one medal is refunded. Therefore, with respect to the above-mentioned regulation regarding the number of combinations of symbols relating to winning, the total number of winning and replaying combinations does not exceed 40/100.

Further, according to the above rule, the number of symbols does not exceed 21 per spinning drum, and the number of all symbol types is 7
Since there is a stipulation that the number of symbols does not exceed 7, there are 7 types of symbols so that the number of combinations of symbols is the maximum, and 2 for one spinning drum.
It is normal to have one design. However, in order to satisfy the above-mentioned rules regarding re-play, the number of winning combinations, which was 7 types in the spinning drum game machine before the rules for re-play were set, was reduced to 6 and a new combination for re-play was newly added. The current situation is to take measures to set it. In other words, in the rotating body type gaming machine before the regulation of the re-game was set, all seven types of symbols were used as the symbols relating to the winning, whereas in the current rotating body type gaming machine, the winning type is used. There are 6 types of such symbols, and the remaining 1 type is used exclusively for replaying.

[0005]

However, in the above technique, the variety of games is reduced by reducing the number of types of winning combinations from seven types to six types. For example, re-playing for one specific wheel is performed. When a special design is displayed, even if you operate the remaining wheels, there are only options to play again or fail to win game medals, and the selection range of game results narrows. There was a problem that the interest of the person was halved.

The present invention is intended to solve the above problems, and enables replaying without reducing the types of winning combinations, while satisfying the regulations concerning gaming machines. An object of the present invention is to provide a spinning-roller type gaming machine in which the variety of winnings is not reduced and the selection range for the result of the game is not narrowed only by stopping one spinning drum.

[0007]

In order to achieve the above-mentioned object, the present invention provides at least three rotating drums in which a plurality of types of symbols are arranged so as to circulate in a predetermined number greater than the types of symbols, and each rotating drum. Display means for extracting a part of the symbols provided in each of the specified number and displaying them side by side in a row of a specified number of rows, driving means for driving each drum so that the symbols displayed on the display means circulate, and all times Starting means for starting the driving of the barrel, stopping means for individually stopping the driving of the barrel by external operation, and determination of winning or replaying when the symbols of the barrels displayed on the display means are arranged in a predetermined relationship The determination means is provided, and at least one spinning cylinder is not provided with a special symbol as a special symbol for one specific type of symbols, and the determination symbol is all the symbols arranged on the line set in the display device. Is it the same with the revolving body? Is determined to be a prize when the special design provided on the other one specific spinning drum appears on the line, and the special design provided on another specific one spinning drum appears on the line, and the rest It is characterized in that it is determined as a re-game when a specific type of symbol, which is not a special symbol provided on all the spinning drums, is lined up on the line.

Further, when the number of rotating drums is three, it is desirable that the rotating drum without the special pattern is the central rotating drum.

[0009]

According to the above construction, at least one of the plurality of rotating drums is not provided with a special symbol, and the determining means is all the symbols arranged on the line set in the display means. If the special symbols provided on the same or other specific one of the spinning drums appear on the line, it is determined that there is a prize, and if there are seven types of symbols, there are six types. There is a state where the symbols are lined up in a straight line, and 1
Since the winning symbol is determined when the special symbol is displayed on the display means for each spinning drum, the number of symbol combinations relating to the winning symbol can be set to seven types.

On the other hand, the judging means judges that the special symbol provided on one particular rotating cylinder different from the rotating cylinder judged to be a prize in the display of the special symbol appears on the line, and judges that it is a winning prize. If a special symbol provided on one specific spinning drum appears on the line, and if a specific type of symbol that is not a special symbol provided on all the remaining spinning drums is lined up on the line, it is determined to be a re-game. , Replay can be designated without using a special design for replay. That is, since there is no special symbol for replay, when the player stops one spinning drum, any option of winning, replaying, and failing to obtain a game medal is left. Therefore, the player's interest can be kept without narrowing the selection range for the result of the game.

[0011]

[Embodiment] In this embodiment, a spinning drum is a wheel, and a mechanical spinning drum type game machine in which a wheel is rotationally driven by a driving means such as a motor is exemplified, but the present invention stores data relating to symbols. It also includes an electronic spinning drum type game machine in which a spinning drum is configured by the above memory and each data is cyclically read by the driving means. In such an electronic spinning type game machine, a display element capable of displaying characters and figures is used as a display means.

As shown in FIG. 2, the spinning drum type game machine of the present invention is formed in a cylindrical shape and has a plurality (2 in this embodiment) on the outer peripheral surface.
The number of the wheels is one, but the number may be 21 or less according to the rules.) Three wheels 1a, 1b, 1c with symbols are described. The wheels 1a, 1b, 1c are arranged coaxially and have substantially the same diameter, and are rotationally driven by a driving means 2 equipped with a motor or the like. The driving means 2 is started by operating the starting switch 3 which is a starting means after inserting the game medal into the game medal insertion slot (not shown). Further, if the stop switches 4a, 4b, 4c, which are stop means provided corresponding to the wheels 1a, 1b, 1c, are operated, the rotations of the wheels 1a, 1b, 1c are stopped individually. Start switch 3 and stop switch 4a, 4b,
Information such as the operation state of 4c and the insertion state of game medals,
The driving means 2 is input to the control / determination unit 7, and is controlled to a state according to the information input to the control / determination unit 7. The wheels 1a, 1b, 1c, the driving means 2, etc. are built in the casing 5, and the start switch 3, the stop switches 4a, 4b,
The operation portion 4c is exposed on the front surface of the casing 5. Also,
Display windows 6a, 6b, 6c as display means are opened in the casing 5 so that three symbols provided on each wheel 1a, 1b, 1c are exposed. Therefore, 3 × 3 = 9 symbols are exposed through the display windows 6a, 6b, 6c. The configuration up to this point is the same as that of the conventional rotating-type gaming machine.

By the way, the wheels 1a, 1b, 1c are shown with seven kinds of symbols as shown in FIG. 1 (While the wheels 1a, 1b, 1c are endless, they are in an unfolded state in FIG. 1). Shown). Here, in FIG. 1, for simplification of description, the design is shown by numbers or alphabetical characters, but it is usually shown by figures such as “bar”, “bell”, “orange”. Further, in the following description, the three wheels 1a, 1b, 1c will be referred to as a first wheel 1a, a second wheel 1b, and a third wheel 1c in order from the left. Table 1 shows each wheel 1a, 1
b, 1c represents the frequency of appearance of the symbols, and as is clear from FIG. 1 and Table 1, in the symbols depicted on the second wheel 1b, “C” (“cherry”) out of the seven types of symbols that can be used. (Meaning the figure) is excluded. That is, in this embodiment, the symbol "C" is set as the special symbol.

[0014]

[Table 1]

Special symbols are treated differently from other symbols. That is, all the wheels 1a, 1b, 1c
About, about the same symbol is lined up on the line formed by the symbols appearing in the display windows 6a, 6b, 6c, it is a prize, and the special symbol written on the first wheel 1a is the display windows 6a, 6b, 6c When it appears in the display window 6a, 6
No matter which symbol appears on b or 6c, the prize will be awarded. Here, the line is 3 in the direction in which the wheels 1a, 1b, 1c are arranged with respect to the 3 × 3 symbols appearing in the display windows 6a, 6b, 6c.
It means a line on five straight lines of two straight lines and two diagonal lines, and wheels 1a, 1b, depending on the number of game medals inserted.
Whether only one of the three lines in the arrangement direction of 1c is valid, or all three lines are valid,
It is possible to select whether or not to validate all five lines, which are two lines in the diagonal direction added to three lines.

On the other hand, the special symbol is also provided on the third wheel 1c, and when the special symbol provided on the third wheel 1c appears in the display windows 6a, 6b, 6c, it passes through the special symbol. When the symbols appearing in the display windows 6a, 6b, 6c for the first wheel 1a and the second wheel 1c on the line are the same and the symbol is "P" or "7", it is a replay game. The determination of the combination of symbols relating to winning and replaying is performed by the control / determination unit 7 as a determination means. The control / judgment unit 7 can use a microcomputer or can be configured by mechanical means, and selects 1 line, 3 lines, 5 lines according to the number of inserted game medals, or relates to winning a prize. For example, payout of game medals may be performed at a multiplication rate according to the type of symbol combination. Table 2 shows the types and number of combinations of symbols relating to winning and replaying when the symbols are arranged as shown in FIG. In Table 2, "-" indicates that it is an arbitrary pattern.

[0017]

[Table 2]

As shown in Table 2, there are seven kinds of symbol combinations related to winning a prize ("C--" is counted as one kind).
However, there are two types of symbol combinations relating to the re-game. Here, if the symbols are arranged as shown in FIG. 1, the number of all combinations of symbols is 21 ×, as is clear from Table 2.
There are 21 × 21 = 9261 ways, the number of symbol combinations relating to winning is 1011 and the number of symbol combinations relating to re-playing is 105. Therefore, considering one line, winning including re-playing The number of such combinations is (1011 + 10
5) ÷ 9261 × 100≈12.05%, which is 100
It is possible to meet the requirement of not exceeding 11/40 and not exceeding 100/100. Similarly, considering 5 lines, the number of symbol combinations relating to winning is 5055, the number of symbol combinations relating to re-playing is 525, and the number of symbol combinations relating to winning including re-playing is 5580. Get on the street. Here, in the case of 5 lines, two types of combinations of winning symbols appear at the same time in the display windows 6a, 6b, 6c, and combinations of winning symbols and replay symbols are displayed simultaneously. Since it may appear in the windows 6a, 6b, 6c, the control / judgment unit 7 handles these cases as one prize. That is, the number of cases in which a plurality of winnings are overlapped or the number of winnings and replays are overlapped is 1885, so 5580-1885 = 36.
There are 95 ways, 3695 ÷ 9261 × 100% = 3
Since it is 9.90%, it is 10 even for 5 lines.
It is possible to meet the requirement that the value exceeds 11/0 and does not exceed 40/100.

As described above, in the present invention, the re-game can be introduced without reducing the number of winning symbol combinations. Also, any one of the wheels 1a, 1
At the time when b, 1c is stopped, there is a possibility of winning, replaying, and failure to obtain game medals, and the winning of game medals even when the two wheels 1a, 1b, 1c are stopped. If the failure of is not confirmed, the possibility of winning and replaying remains, and the interest of the player can be maintained despite the introduction of replaying.

It is needless to say that FIG. 1 is only one example of the symbol arrangement, and various arrangements other than this can be adopted. Further, in the present embodiment, the two types of symbols "P" and "7" are used as the symbols allowing the replay, but the number of the symbols allowing the replay may be one. Further, if it is not necessary to set the re-game, the combination of the symbols relating to the re-game in this embodiment may be used for the combination of the symbols relating to the winning. The number of the wheels 1a, 1b, 1c may be three or more, and the display windows 6a, 6b, 6c are not limited to those displaying three symbols.

[0021]

As described above, according to the present invention, the symbols arranged on the line set in the display means are the same for all the rotating drums, or a special symbol provided on another specific rotating drum is on the line. When it appears in, it is judged as a winning prize, and a special symbol provided on another specific spinning drum appears on the line, and a specific type of symbol that is not a special symbol provided on all the remaining spinning drums Since it is determined as a re-game when lined up on the line, the number of types of symbol combinations relating to winning can be set to the same number as the types of symbols, and the re-game can be designated without using a symbol dedicated to the re-game. It has the effect of being able to. That is,
Since there is no special design for replay, when the player stops one spinning drum, the player will have all the options of winning, replaying, and failure to win the game medal. There is an advantage that the player's interest can be maintained until the end of the game without narrowing the selection range for. After all, it is possible to introduce re-games into the result of the game without reducing the types of combinations of symbols related to winning, and while allowing re-games, the diversity of winning is not reduced, and An advantage is that it is possible to provide a spinning-roller type gaming machine in which the selection range for the result of the game is not narrowed by stopping one spinning drum.
