[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball game machine such as a pachinko machine, a revolving game machine, and other various game machines.
[0002]
[Prior art]
In a ball game machine such as a pachinko machine, the game board is provided with variable symbol display means having a plurality of symbol display parts, and start means for detecting entry or passage of the game ball, and the start means receives the game ball. When detected, the symbols on each symbol display section of the variable symbol display means are changed for a predetermined time, and when the stop symbol after the change becomes a specific jackpot symbol, the special winning means is opened / closed a predetermined number of times, or other After winning a game ball that has won the winning means of the game, after passing through the special operating area inside it, each time the game ball wins the specific starting means, the other big winning means are opened and closed a predetermined number of times, etc. To generate profits and return profits.
[0003]
In the CR machine, when the stop symbol of the variable symbol display means stops at a predetermined jackpot symbol and a jackpot occurs, the probability variation formula is such that the probability of jackpot occurrence from the next time is switched to a high probability of about 10 times. There is.
[0004]
[Problems to be solved by the invention]
In this type of pachinko machine, once a winning symbol is generated on the side of the changing symbol display means, a large number of game balls win the winning prize means while the winning prize means repeats opening and closing operations. A lot of profits are returned, especially in the case of probability fluctuation formulas, if a big hit occurs with a predetermined jackpot symbol, the player will be in a high probability state and it will be easy to generate a big hit. There is an advantage that you can play games while expecting
[0005]
On the other hand, since the probability of jackpot occurrence is normally set to about 1/250 to 1/450 with respect to the number of fluctuations of the fluctuation symbol display means, a great return of profit can be expected. There is a great risk of spending money.
[0006]
Therefore, the conventional pachinko machine has a drawback that it is not only capable of meeting the needs of all the players, but it is only eager.
[0007]
In other words, when considering many players who play games on pachinko machines, there are not many returns profits for the players, but not all players always expect a great return of profits. Some people want to play games steadily while enjoying the fun of the game.
[0008]
However, while conventional pachinko machines can be expected to have a large return profit, they always have a risk of spending a large amount of money, and each player is not willing to like it. There is a disadvantage that the game is inevitably played under high-return gaming conditions and cannot fully meet the needs of all players.
[0009]
An object of the present invention is to provide a gaming machine in which a player can select a game condition based on his / her own judgment and can play an interesting game under the selected game condition.
[0010]

Or when 10 game balls are won. The inside of the special winning means 25 is divided into three, and the center is a special operation area 32.
[0020]
FIG. 4 shows a control system of the mode-selective pachinko machine 1, 33 is a random number generating means, and this random number generating means 33 includes two types of game modes with different game conditions, as will be described later with reference to FIG. That is, the first random number generator 34 and the second random number generator 35 are provided in accordance with the first game mode A of the game type and the second game mode B of the solid type.
[0021]
The first random number generator 34 is adapted to the needs of a player who desires a game under high-risk / high-return gaming conditions in anticipation of a large return profit, The generated random numbers are set so that the jackpot is generated with a probability of about 1/380 with respect to the number of fluctuations.
[0022]
On the other hand, the second random number generator 35 is adapted to the needs of the player who wants to play a game under steady gaming conditions, with an emphasis on the fun of the game itself rather than some of the return profit. Thus, the generated random numbers are set so that the jackpot is generated with a probability of about 1/200.
[0023]
36 is a random number lottery determination means. When the starting means 23 detects a game ball, the random number value of the first random number generator 34 or the second random number generator 35 at the time of detection is lottery, and the lottery random number is a big hit random number It is determined whether the random number is a reach random number or an outlier random number.
[0024]
37 is a changing symbol processing means, and when the starting means 23 detects a game ball, the display symbols of each symbol display section 30 of the changing symbol display means 29 are changed for a predetermined time and, for example, random numbers drawn by the random number lottery judging means 36 Depending on the jackpot random number, reach random number and off-random number drawn by the random number lottery judging means 36 so that the stop symbol of each symbol display unit 30 becomes a jackpot symbol such as “7/7/7” when is a jackpot random number The stop symbol of each symbol display unit 30 is controlled.
[0025]
The jackpot symbols displayed on the variation symbol display means 29 are the same in the first game mode A and the second game mode B, and are “1 · 1 · 1”, “2 · 2 · 2”, There are 15 types such as “3.
[0026]
38 is a big winning control means, which opens the big winning means 25 when the random number lottery judging means 36 determines that it is a big hit random number, and when the predetermined time has elapsed from this opening or when ten game balls have won, When the game ball passes through the special operation area 32 and reaches a predetermined number of times, that is, up to 16 times in the case of the first game mode A, and in the case of the second game mode B. Has a function of controlling the winning means 25 to repeat the opening / closing operation up to nine times.
[0027]
39 is a probability variation means, and the random number lottery determination means 36 draws a jackpot random number, and the stop symbol of the fluctuation symbol display means 29 at that time is set to “1 · 1 · 1”, “3.3”・ When the odd number of 7 patterns such as “3” is obtained, the probability that the random number generating means 33 generates the big hit random number after the big hit processing is switched from the low probability of 1/380 to the high probability of about 1/38, Further, when the stop symbol of the fluctuation symbol display means 29 becomes a symbol other than the one for the high probability after the high probability state is entered, the probability is returned to the low probability.
[0028]
40 is a game mode setting means. As shown in FIG. 5, the game mode setting means 40 has two types of game modes A and B, ie, a first game mode A and a second game mode B having different game conditions. Is set. The first game mode A is tailored to the needs of a player who wants a game under high-risk / high-return gaming conditions in anticipation of a large return profit, and the second game mode B is The game is tailored to the needs of a player who wants to play a game under solid game conditions, with an emphasis on the fun of the game itself rather than some of the return profit.
[0029]
41 is a mode selection means for selecting the game modes A and B set in the game mode setting means 40, and when the player operates the push button type mode selection button 42, the first game mode A and the second game mode are selected. One of the game modes A and B used for the actual game is selected from the mode B. As shown in FIG. 1, the mode selection button 42 is arranged on the left side of the lower plate 9 at the lower part of the front frame 4 so that the player can easily operate it.
[0030]
The mode selection means 41 is configured to send a mode selection signal to a management device such as a computer via an external output terminal, and the management device side summarizes the mode selection status etc. of each pachinko machine 1 together with data. To manage.
[0031]
The game mode control means 43 controls the random number generation means 33, the random number lottery determination means 36, the big prize control means 38 and the liquid crystal display means 22 in accordance with the respective game modes A and B selected by the mode selection means 41. At the same time, the selection of the game mode by the mode selection means 41 is prevented during the probability fluctuation by the probability fluctuation means 39.
[0032]
That is, the game mode control means 43 validates the random number from the first random number generator 34 when the first game mode A is selected, and the random number from the second random number generator 35 when the second game mode B is selected. Thus, the probability of jackpot occurrence in the changing symbol display means 29 is changed between the first game mode A and the second game mode B, and the generated random numbers from the random number generators 34 and 35 are jackpot random numbers. Whether or not the random number lottery determination means 36 controls the number of times of opening and closing of the big winning means 25 after the jackpot is generated is 16 times in the first game mode A and 9 in the second game mode B. The game information related to the selection of the game modes A and B, such as the game mode A and B selected at the time of selection and the game modes A and B and the game conditions in the game modes A and B when the game modes A and B are selected. A function of displaying an image on the liquid crystal display means 22, and a variation symbol display means 29 Has by the mode selecting means 41 when the moving operation and in the high-probability state gaming mode A, and a function of preventing the selection of the B.
[0033]
Next, the operation of the mode-selective pachinko machine 1 will be described.
[0034]
In this pachinko machine 1, the game mode setting means 40 sets two types of game modes A and B, which are a high risk / high return type first game mode A and a solid type second game mode B. The player can select one of the game modes A and B by operating the mode selection button 42 of the mode selection means 41, and can actually play the game in the selected game mode A and B.
[0035]
That is, since the game mode setting means 40 is normally on the first game mode A side, a player who desires a game in the first game mode A may start the game in that state.
[0036]
However, if the player desires a game in the solid second game mode B, the mode selection button 42 is operated prior to the start of the game, and the second game mode is selected from the two game modes. Select B.
[0037]
Then, the game mode control means 43 operates according to the selection result of the mode selection means 41 to control the random number generation means 33, the random number lottery determination means 36, the big prize control means 38, and the liquid crystal display means 22. That is, the random number generators 34 and 35 of the random number generator 33 always generate random numbers according to the respective conditions. Therefore, when the mode selection means 41 selects the first game mode A, the first random number generator When the second game mode B is selected, the random number from the second random number generator 35 is made valid, and the random number lottery judging means 36 generates the random numbers generated from the random number generators 34 and 35. Is controlled by lottery.
[0038]
When the first game mode A is selected, the grand prize control means 38 sets or restricts the maximum opening / closing frequency of the big prize means 25 to 16 times, and when the second game mode B is selected, it is set or restricted to 9 times. To do.
[0039]
Therefore, when the first game mode A is selected, the probability of winning the jackpot on the changing symbol display means 29 is 1/380, whereas once the jackpot is generated, the winning prize means 25 is up to 16 Since the opening / closing operation is repeated up to the number of times, the game can be played with great risk but expecting a great return of profit.
[0040]
On the other hand, when the second game mode B is selected, the probability of jackpot on the changing symbol display means 29 is 1/200, which is higher than that of the first game mode A, but the jackpot is generated. However, the number of times of opening / closing the special winning means 25 is reduced to a maximum of nine. For this reason, the player who has selected the second game mode B can reduce the extreme difference in winning and losing, so that it is possible to play the game steadily while enjoying without being particular about winning or losing.
[0041]
Further, when the first game mode A is selected, the fact that the first game mode A is selected and the game condition in the game mode A is the second game mode B when the second game mode B is selected. And the gaming conditions in the gaming mode B are displayed on the liquid crystal display means 22, respectively. Therefore, the player can check the game modes A and B that he / she has selected and the game conditions in the game modes A and B, and can understand the game conditions and be convinced to play the game interestingly. .
[0042]
In the game, after the player appropriately selects the game modes A and B, the launching handle 11 of the launching means 10 is operated with the game ball placed in the upper plate 7. Then, the game balls on the upper plate 7 are supplied one by one to the launch position of the launch rail in conjunction with the launch operation of the launch means 10, and the game balls 5 are sequentially hit along the guide rails 21 by hitting the game balls with the striker. Fire at the top of the.
[0043]
The game ball launched to the upper side of the game board 5 wins the winning slot 24 etc. while falling along the board surface of the game board 5, or falls to the lower part of the game board 5 and enters the out slot 28. Go past the game board 5 to the back.
[0044]
When the game ball wins the starter 23 and the starter 23 detects the game ball, each random number generator 34, 35 of the random number generator 33 repeatedly generates a predetermined random number. The random number lottery determination means 36 draws a random number at the time when the game ball is won, and determines whether or not the random number is a big hit random number. At the same time, the fluctuation symbol processing means 37 has each symbol display section of the fluctuation symbol display means 29. Thirty symbols are changed for a predetermined time.
[0045]
At this time, the changing symbol processing means 37, after changing the symbols of each symbol display unit 30, according to the determination result determined by the random number lottery determination means 36, the stop symbol corresponding to each of the jackpot random number, reach random number and outlier random number The variable symbol display means 29 is controlled to stop at. If the random number is a jackpot random number, the stop symbol of each symbol display unit 30 stops at a jackpot symbol such as “7/7/7”, and if the random symbol is an outlier random number including a reach random number, each symbol display unit 30 The stop symbol stops at an off symbol other than the jackpot symbol.
[0046]
In the case of the first game mode A, the random number lottery determination means 36 draws the random number of the first random number generator 34, and the random number lottery determination means 36 determines whether or not the random number is a big hit random number generated at 1/380. To do. Further, in the case of the second game mode B, the random number lottery determination means 36 draws the random number of the second random number generator 35, and the random number lottery determination means 36 determines whether or not the random number is a big hit random number generated at 1/200. judge.
[0047]
When the lottery random number in the random number lottery judging means 36 is a big hit random number, the big winning means 25 is released via the big winning control means 38, and the game ball falling from the upper side along the game board 5 wins the big winning means 25. It becomes easy to do. Then, when 10 game balls are won in the big winning means 25 or when a predetermined time has elapsed from the release, the big winning control means 38 is operated and the big winning means 25 is closed.
[0048]
If a game ball won while the big winning means 25 is opened passes through the central special operation area 32, the big winning means 25 is closed and then opened again. In the first game mode A, the big winning means 25 repeats opening and closing up to 16 times, so that the game ball can easily win the big winning means 25, and a great profit can be returned to the player. In the second game mode B, the maximum winning means 25 is a maximum of nine times.
[0049]
When a game ball wins the big winning means 25, the ball payout means 16 pays out the game balls in the prize ball tank 14 to the upper plate 7 at a ratio of 15 to one winning ball, and the number of game balls won is obtained. Return the profits to the players.
[0050]
Incidentally, the maximum payout number of game balls to be paid out by the ball paying means 16 when one big hit is generated is 2400 in the first game mode A and 1350 in the second game mode B.
[0051]
In this way, by changing the operating conditions of the big winning means 25 according to each game mode A, B, it is not necessary to change the number of ball payout means 16 of the ball payout means 16 for each game mode A, B, the ball payout means 16 controls are easy. Therefore, in combination with changing the jackpot occurrence probability in the changing symbol display means 29, the game conditions for each of the game modes A and B can be easily changed.
[0052]
Even when the symbol of the variation symbol display means 29 becomes a jackpot symbol, if the stop symbol is an odd symbol especially for probability variation, the probability variation means 39 works, and the first game mode A and the second game mode B Regardless of the above, the probability of jackpot in the changing symbol display means 29 from the next time is switched from a low probability of 1/380 to a high probability of 1/38. For this reason, in both cases of the first game mode A and the second game mode B, if a jackpot occurs in odd symbols, the probability that a jackpot will occur again due to the probability variation by the probability variation means 39 becomes very large, Can motivate players to play games.
[0053]
Note that when the lottery random number is off and the random number is random, the symbol of the variation symbol display means 29 only fluctuates for a predetermined time, and the big winning means 25 and the like do not open and close.
[0054]
The game modes A and B can be selected by operating the game mode control means 43 if the player operates the mode selection button 42 of the mode selection means 41 even during the game. Therefore, the player can continue the game by selecting either the first game mode A or the second game mode B as needed in consideration of his own money that can be invested in the game. It is.
[0055]
However, if the stop symbol of the fluctuation symbol display means 29 is a jackpot symbol, and the stop symbol at that time is an odd symbol, the probability fluctuation means 39 works and is in a high probability state, so the mode selection means 41 mode Even if the selection button 42 is operated, the selection signal is blocked by the game mode control means 43 and the game modes A and B cannot be selected.
[0056]
Therefore, start the game in the second game mode B with a high probability of jackpots, switch to the first game mode A after the jackpot has occurred, and aim to return profits over the original first game mode A You can prevent anything.
[0057]
Note that the game modes A and B cannot be changed even when the variation symbol display means 29 is in a variation operation.
[0058]
The random number generation means 33 includes a first random number generation section 34 for the first game mode A and a second random number generation section 35 for the second game mode B. The mode selection means 41 and the first random number generation section 34 Since the random number from one random number generator 34, 35 of the second random number generator 35 is selected and used, when changing the jackpot probability in the program using the same generated random number In comparison, it is easy to calculate the characteristics of the design probability at the manufacturing stage of the pachinko machine, and the characteristics of the predetermined design probability can be easily maintained even when a complicated game configuration is adopted.
[0059]
When the game modes A and B are selected, the player can easily select the game modes A and B by operating the mode selection button 42 because the mode selection button 42 arranged at the lower front side of the front frame 4 may be operated. .
[0060]
As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. For example, in the embodiment, two types of game modes A and B, which are a first game mode A and a second game mode B, are illustrated, but three or more types of game modes may be provided.
[0061]
The game conditions in each of the game modes A and B are different in the embodiment in the jackpot occurrence probability in the variable symbol display means 29 and the operating conditions of the big winning means 25, but the number of balls paid out for one winning ball May be changed for each game mode A, B. In short, it is sufficient if the game conditions change for each game mode A, B.
[0062]
Further, the mode selection means 41 may be of a type that can be easily operated by the player, and other than the mode selection button 42 may be used. Even when the mode selection button 42 is used, the arrangement position may be any position where the player can easily operate, such as the front edge of the upper plate 7.
[0063]
When the starting means 23 detects a game ball during the fluctuation of the fluctuation symbol display means 29, a predetermined number of detections are stored, and after the fluctuation symbol display means 29 finishes the fluctuation operation, the fluctuation symbols corresponding to the stored number are stored. In the pachinko machine in which the display means 29 is variably operated, selection of the game modes A and B by the mode selection means 41 may be blocked by the game mode control means 43 when there is a predetermined number of detected memories. Further, in addition to the pachinko machine 1, not only a ball game machine such as an arrangement ball machine, but also other swirl type game machines can be similarly implemented.
[0064]
