Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ball-and-ball game machine such as a pachinko machine, a torso-type game machine, and various other game machines.
[0002]
[Prior art]
In a ball-and-ball game machine such as a pachinko machine, a game board is provided with a variable symbol display means having a plurality of symbol display portions, and a starting means for detecting entry or passage of a game ball, and the starting means sets a game ball. When detected, the symbol of each symbol display portion of the variable symbol display means is varied for a predetermined time, and when the stopped symbol after the variation becomes a specific jackpot symbol, the special winning means is opened and closed a predetermined number of times, or otherwise. After the game ball that has won the prize means passes through the special operation area inside it, every time the game ball lands on the specific starting means, the other big prize means is opened and closed a predetermined number of times, and the like, a jackpot right in favor of the player Is generated to return profits.
[0003]
Also, in the CR machine, when the stop symbol of the variable symbol display means stops at a predetermined jackpot symbol and a jackpot occurs, a probability variation type in which the probability of occurrence of the jackpot 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 big hit occurs on the fluctuating symbol display means side, while the large prize means repeats the opening and closing operation, a large number of game balls win the big prize means, and the player A great deal of profit is returned, especially in the case of the probability variation formula, when a big hit occurs with a predetermined big hit symbol, a high probability state continues and a big hit easily occurs, so the player can return a great profit. There is an advantage that the game can be performed while expecting the game.
[0005]
On the other hand, since the probability of occurrence of a jackpot is usually set to about 1/250 to 1/450 with respect to the number of times of change of the variable symbol display means, a great profit can be expected to be returned, but a large amount of money is required for the game. It involves the great risk of spending money.
[0006]
Therefore, the conventional pachinko machine only has a drawback that it only excites gambling and cannot sufficiently meet the needs of all players.
[0007]
That is, when considering many players playing a game on a pachinko machine, the return profit for the player is not far from being large, but not all players always expect a great return of the game. Some people want to play the game steadily while enjoying the fun of the game.
[0008]
However, although conventional pachinko machines can be expected to have a large return profit, they always have the danger of spending a large amount of money, and each player, whether or not they like it, has a high risk There is a drawback that the game must be played under high return game conditions, and the needs of all players cannot be sufficiently answered.
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a gaming machine that allows a player to select a game condition at his / her own discretion and play a game with the selected game condition.
[0010]
[Means for Solving the Problems]
The present invention is based on the detection of a game ball by the starting means 23, the symbol of the fluctuating symbol display means 29 is fluctuated for a predetermined time, and the player after the fluctuating display of the fluctuating symbol display means 29 becomes a predetermined jackpot symbol. When the starting means 23 detects a game ball during the fluctuation operation of the fluctuation symbol display means 29, the detection is stored, and after the fluctuation symbol display means 29 ends the fluctuation operation, In a gaming machine in which the variable symbol display means 29 is operated in a variable manner by the number of storages, a plurality of game modes A and B having different game conditions are provided, and an actual game is selected from the plurality of game modes A and B. Mode selection means 41 for selecting one of the game modes A and B used for the game, and a game for preventing the selection of the game modes A and B by the mode selection means 41 when the detection is stored. And a mode control means 43.

[0019]
The special winning means 25 is opened when the stop symbol of each symbol display section 30 of the variable symbol display means 29 becomes a specific big hit symbol such as "7.7.7", and whether a predetermined time has elapsed since the release. , Or when ten game balls are won. The inside of the special winning means 25 is divided into three parts, the center of which is a special operation area 32.
[0020]
FIG. 4 shows a control system of the pachinko machine 1 of the mode selection type. Reference numeral 33 denotes random number generating means. The random number generating means 33 includes two types of game modes having different game conditions, as will be described later with reference to FIG. That is, a first random number generator 34 and a second random number generator 35 are provided for the first game mode A of the game type and the second game mode B of the solid type.
[0021]
The first random number generation unit 34 is adapted to the needs of a player who desires a game under high-risk, high-return game conditions in expectation of a great return profit. The generated random number is set so that a big hit occurs with a probability of about 1/380 with respect to the number of changes.
[0022]
On the other hand, the second random number generating unit 35 is adapted to the needs of a player who desires a game under sound game conditions, focusing on the interest of the game itself rather than the return profit. The generated random number is set so that a big hit occurs with a probability of about 1/200.
[0023]
36 is a random number lottery judging 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 the detection is randomly selected, and the random number is determined as a jackpot random number. , Reach random numbers or out-of-order random numbers.
[0024]
Numeral 37 denotes a variable symbol processing means which, when the starting means 23 detects a game ball, changes the display symbol of each symbol display section 30 of the variable symbol display means 29 for a predetermined time and, for example, random numbers selected by the random number lottery determination means 36. Is a jackpot random number, according to the jackpot random number, the reach random number, and the out-of-range random number drawn by the random number lottery determination means 36 so that the stop symbol of each symbol display unit 30 becomes a jackpot symbol such as “7.7.7”. The stop symbols of each symbol display section 30 are controlled.
[0025]
In addition, the big hit symbol displayed on the variable symbol display means 29 is the same in the case of the first game mode A and the second game mode B, and is “1.1.1”, “2.2.2”, There are 15 types, such as "3.3.3".
[0026]
Reference numeral 38 denotes a special winning control means, which opens the special winning means 25 when the random number lottery judging means 36 determines that it is a jackpot random number. When a predetermined time has elapsed from this release or when ten game balls have won, the special winning means 25 is controlled. When the game ball passes through the special operation area 32 until the predetermined number of times is reached, that is, up to 16 times in the first game mode A, and up to 16 times in the second game mode B Has a function of controlling the large winning means 25 to repeat the opening and closing operations up to nine times.
[0027]
Numeral 39 denotes a probability varying means. The random number lottery judging means 36 randomly selects a jackpot random number, and "1.1.1", "3.3", in which the stop symbol of the variable symbol display means 29 at that time is set for high probability. When the seven odd symbols such as "3" are obtained, the probability of the jackpot random number being generated by the random number generator 33 after the jackpot process is switched from a low probability of 1/380 to a high probability of about 1/38, Further, when the stopped symbol of the fluctuating symbol display means 29 becomes a symbol other than the symbol for high probability after the high probability state is reached, the probability is returned to the low probability.
[0028]
Numeral 40 denotes 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 of a first game mode A and a second game mode B having different game conditions. Is set. The first game mode A is adapted to the needs of a player who desires a game under high-risk, high-return game conditions in expectation of a great return profit, and the second game mode B is The game is tailored to the needs of a player who wishes to play a game under sound game conditions, focusing on the interest of the game itself rather than the return profit.
[0029]
Reference numeral 41 denotes a mode selection means for selecting the game modes A and B set in the game mode setting means 40. When the player operates a 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 modes B 1 and B 2. As shown in FIG. 1, the mode selection button 42 is disposed at the lower part of the front frame 4 and on the left side of the lower plate 9 so that the player can easily operate it.
[0030]
The mode selection means 41 sends a mode selection signal to a management device such as a computer via an external output terminal, and the management device tallies the mode selection status of each pachinko machine 1 together with data. And manage it.
[0031]
Reference numeral 43 denotes a game mode control unit which controls the random number generation unit 33, the random number lottery determination unit 36, the special winning control unit 38, and the liquid crystal display unit 22 according to each of the game modes A and B selected by the mode selection unit 41. At the same time, the selection of the game mode by the mode selecting means 41 is prevented during the probability changing by the probability changing means 39.
[0032]
That is, the game mode control unit 43 validates the random number from the first random number generation unit 34 when the first game mode A is selected, and the random number from the second random number generation unit 35 when the second game mode B is selected. In the first game mode A and the second game mode B, the jackpot occurrence probability in the variable symbol display means 29 is changed, and the random numbers generated from the random number generators 34 and 35 are the jackpot random numbers. The random number lottery judging means 36 determines whether or not the large winning prize 25 has been opened and closed 16 times in the first game mode A and 9 times in the second game mode B after the jackpot. And game information related to the selection of the game modes A and B such as the selected 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. The lcd display hand Includes a function of displaying image 22, the game mode A by the mode selecting means 41 when the fluctuations during operation and a high probability state variation symbol display unit 29, and a function of preventing the selection of the B.
[0033]
Next, the operation of the mode selection type pachinko machine 1 will be described.
[0034]
In the pachinko machine 1, the game mode setting means 40 sets two types of game modes A and B: a high-risk, high-return type first game mode A and a solid type second game mode B. By operating the mode selection button 42 of the mode selection means 41, the player can select one of the two game modes A and B, and play the actual game in the selected game mode A or B.
[0035]
That is, since the game mode setting means 40 is normally in the first game mode A side, a player who desires the game in the first game mode A may start the game in that state.
[0036]
However, when the player desires a game in the solid second game mode B 1, the user operates the mode selection button 42 prior to the start of the game and selects the second game mode from the two types of game modes. B may be selected.
[0037]
Then, the game mode control means 43 operates according to the selection result of the mode selection means 41, and controls the random number generation means 33, the random number lottery determination means 36, the special winning control means 38, and the liquid crystal display means 22. That is, since the random number generators 34 and 35 of the random number generator 33 constantly generate random numbers according to the respective conditions, when the first game mode A is selected by the mode selector 41, the first random number generator 34 When the second game mode B 1 is selected, the random number from the second random number generation unit 35 is validated, and the random number lottery determination means 36 generates the random number from the random number generation units 34 and 35. Is determined by lottery.
[0038]
When the first game mode A is selected, the special winning control means 38 sets or restricts the maximum number of times of opening and closing of the special winning means 25 to 16 times, and when the second game mode B is selected, sets or restricts the number to nine times. I do.
[0039]
Therefore, when the first game mode A is selected, the probability of occurrence of a big hit in the variable symbol display means 29 is 1/380. Since the opening / closing operation is repeated up to the number of times, the game can be played while expecting a great return of profit with great risk.
[0040]
On the other hand, when the second game mode B 1 is selected, the probability of occurrence of the jackpot in the variable symbol display means 29 is 1/200, which is higher than that in the first game mode A 1. Also, the number of times the large winning means 25 is opened and closed is reduced to a maximum of nine times. For this reason, the player who has selected the second game mode B can reduce the difference between extreme wins and loses, so that he can play the game steadily while enjoying himself / herself, regardless of winning or losing.
[0041]
Further, when the first game mode A is selected, the fact that the first game mode A has been selected, and when the game conditions in the game mode A have been selected, the second game mode B has been selected when the second game mode B has been selected. Is displayed on the liquid crystal display means 22 and the game conditions in the game mode B are respectively displayed. For this reason, the player can check the game modes A and B selected by himself and the game conditions in the game modes A and B, and can play the game interestingly after knowing and accepting the game conditions. .
[0042]
In the game, after the player appropriately selects the game modes A and B, the player operates the firing handle 11 of the firing means 10 with the game ball placed in the upper plate 7. Then, the game balls of the upper plate 7 are supplied one by one to the firing position of the firing rail in conjunction with the firing operation of the firing means 10, and the game balls are hit with a hitting hammer to sequentially play the game boards 5 along the guide rails 21. Fire at the top side of the.
[0043]
The game balls fired on the upper side of the game board 5 enter the winning opening 24 or the like while falling along the board surface of the game board 5, or fall to the lower part of the game board 5 and enter the out port 28. , Passing behind the game board 5.
[0044]
When the game ball wins the starting means 23 and the starting means 23 detects the game ball, each of the random number generating sections 34 and 35 of the random number generating means 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 jackpot random number. At the same time, the variable symbol processing means 37 changes the symbol display portions of the variable symbol display means 29. 30 symbols are changed for a predetermined time.
[0045]
At this time, the variable symbol processing means 37, after changing the symbol of each symbol display unit 30, according to the determination result determined by the random number lottery determination means 36, a stop symbol corresponding to each of the jackpot random number, the reach random number, and the off-random number. The variable symbol display means 29 is controlled so as to stop at. If the random number is a big hit random number, the stop symbol of each symbol display unit 30 stops at a big hit symbol such as “7 / 7,7”. The stop symbol stops at the off symbol other than the jackpot symbol.
[0046]
In the case of the first game mode A, the random number lottery judging means 36 randomly selects the random number of the first random number generator 34, and judges whether or not the random number is a jackpot random number generated at 1/380. I do. In the case of the second game mode B 1, the random number lottery determination means 36 randomly selects the random number of the second random number generation unit 35 and determines whether or not the random number is a jackpot random number generated at 1/200. judge.
[0047]
When the lottery random number in the random number lottery determination means 36 is a jackpot random number, the special winning means 25 is opened via the special winning control means 38, and the game ball falling from the upper side along the game board 5 wins the special winning means 25. Easier to do. Then, when ten game balls are won in the special winning means 25 or when a predetermined time elapses after opening, the special winning control means 38 works and the special winning means 25 is closed.
[0048]
In addition, if the game ball which has won while opening the special winning means 25 passes through the central special operation area 32, the special winning means 25 is closed and then opened again. In the first game mode A, the special winning means 25 repeatedly opens and closes up to 16 times, so that the game balls can easily win the special 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 up to nine times.
[0049]
When a game ball wins in the special 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 of the winning balls, and the number of the game balls is increased. Return the profits to the players.
[0050]
Incidentally, the maximum payout number of the game balls to be paid out by the ball payout means 16 when one big hit occurs is 2400 in the first game mode A and 1350 in the second game mode B.
[0051]
In this way, by changing the operating condition of the special winning means 25 according to each of the game modes A and B, it is not necessary to change the number of balls to be paid out by the ball payout means 16 for each of the game modes A and B. 16 is easy to control. Therefore, the game condition for each of the game modes A and B can be easily changed in combination with changing the jackpot occurrence probability in the variable symbol display means 29.
[0052]
Even when the symbol of the variable symbol display means 29 becomes a big hit symbol, if the stop symbol is an odd symbol particularly for probability variation, the probability variation means 39 operates to operate the first game mode A and the second game mode B. Regardless of the above, the probability of occurrence of a big hit in the variable 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 any of the first game mode A and the second game mode B, if a big hit occurs in an odd symbol, the probability that the big hit will occur again by the probability change by the probability changing means 39 becomes very large, It can motivate players to play games.
[0053]
When the lottery random number is out of order, the symbol of the variable symbol display means 29 only fluctuates for a predetermined time, and the special winning means 25 and the like do not open or 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 any one of the first game mode A and the second game mode B as needed, considering his or her own money that can be invested in the game. It is.
[0055]
However, when the stop symbol of the variable symbol display means 29 is a big hit symbol and the stop symbol at that time is an odd symbol, the probability change means 39 is in the high probability state and the mode of the mode selection means 41 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, the game is started in the second game mode B having a high jackpot occurrence probability, and after the jackpot has occurred, the game is switched to the first game mode A so as to aim for the return of the profit more than the original first game mode A. Can be prevented.
[0057]
Note that the game modes A and B cannot be changed even when the variable symbol display means 29 is performing a variable operation.
[0058]
The random number generator 33 includes a first random number generator 34 for the first game mode A and a second random number generator 35 for the second game mode B. Since the random number from one of the random number generators 34 and 35 of the second random number generator 35 is selected and used, when changing the jackpot occurrence probability on a program using the same random number, In comparison, it is easy to calculate the characteristics of the design probability at the stage of manufacturing 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 operate the mode selection buttons 42 arranged on the lower front side of the front frame 4 so that the player can easily select the game modes A and B by operating the mode selection buttons 42. .
[0060]
The embodiment of the present invention has been described above, but the present invention is not limited to this embodiment. For example, in the embodiment, two types of game modes A and B, i.e., a first game mode A and a second game mode B, are illustrated, but three or more game modes may be provided.
[0061]
In the embodiment, the game condition in each of the game modes A and B changes the probability of occurrence of the jackpot in the variable symbol display means 29 and the operating condition of the special winning means 25 in the embodiment, but the number of balls paid out for one winning ball. May be changed for each of the game modes A and B. In short, it is sufficient if the game conditions are changed for each of the game modes A and B.
[0062]
Further, the mode selection means 41 may be of any type that can be easily operated by the player, and may be anything other than the mode selection button 42. Even when the mode selection button 42 is used, its position may be any position that can be easily operated by the player, such as the front edge of the upper plate 7.
[0063]
When the starting means 23 detects a game ball while the changing symbol display means 29 is changing, a predetermined number of detections are stored, and after the changing symbol display means 29 completes the changing operation, the changing symbols are stored by the stored number. In a pachinko machine in which the display means 29 is operated to fluctuate, the 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 a predetermined number of detections are stored. In addition to the pachinko machine 1, the present invention can be similarly applied not only to a ball game machine such as an arrange ball machine, but also to other rotating game machines.
[0064]
Note that, in this embodiment, a gaming machine configured to return profits to the player on condition that the display after the change of the change symbol display means 29 becomes a predetermined big hit symbol, or a random number of the random number generation means 33 is randomly selected. Then, the symbol of the variable symbol display means 29 is varied for a predetermined time according to the random number, and the predetermined winning means 25 is operated on condition that the display after the variation of the variable symbol display means 29 becomes a predetermined jackpot symbol. In a gaming machine designed to return profits to a player, a plurality of types of game modes A and B having different game conditions are provided, and a game used for an actual game is selected from the plurality of types of game modes A and B. A mode selecting means 41 for selecting one of the modes A and B is provided.
[0065]
