Description

  In the present invention, a plurality of reels on which symbols are arranged are displayed in rotation, and a winning is determined based on a combination of symbols appearing when rotation of all reels is stopped by a player's reel stop button operation. The present invention relates to a gaming machine represented by a slot machine.

  A gaming machine typified by a conventional slot machine has three rotating reels with symbols arranged on the outer periphery in a display window on the front of the gaming machine. The symbols arranged on the outer periphery are displayed by the player during the game. In order to make it easy to see the design, it is illuminated from the back by a lamp or LED (hereinafter referred to as a backlight) provided inside each reel.

  When the player inserts a medal into the medal slot and operates the start lever, each reel starts rotating and the game starts. When the reels start rotating all at once, the symbols are moved and displayed on the display window.

When the player operates the stop button corresponding to each reel while watching the symbols that are moved and displayed, each reel is stopped and any symbol is stopped on the winning line.
There are 5 winning lines. As the number of inserted medals increases to 1, 2, and 3, the number of valid lines increases to 1, 3, and 5. Yes. As a result, when a predetermined symbol combination is aligned on a valid winning line, a winning is awarded and a medal is paid out.

When the player is notified of the internal winning, the player operates the stop button at a timing so that the symbol corresponding to the winning combination is stopped on the valid winning line.
If the symbols corresponding to the winning combination are arranged on the effective winning line and the winning combination can be awarded, the number of medals corresponding to the winning combination can be paid out. Also, if the symbols corresponding to the combination cannot be prepared, the inserted medal will be lost.

  The combination corresponding to the type of symbol combination (also referred to as an accessory) is determined in advance, and if those symbols are stopped on the winning line and can be won, a payout is made according to the combination. Done. When the stopped symbol is a big bonus (BB) or regular bonus (RB) symbol, the game can be shifted to a special game such as a BB game or an RB game, respectively, and a big profit is given to the player. Each bonus game has a predetermined game configuration. For example, an RB game can win a predetermined character with a high probability, and for example, 15 medals are paid out for each winning game. The The RB game ends when the number of games of up to 12 is consumed or when a maximum of 8 wins are achieved. The BB game is a combination of a BB game in which a small role is generated with a high probability (also referred to as a small role game) and the above RB game. When the RB game is executed three times, the game ends. In recent years, there is also a game in which the BB game is terminated on condition that the number of medals acquired during the BB game has reached a predetermined upper limit.

  The lottery probability of the winning combination by the internal lottery is set in advance corresponding to the gaming state and the betting number of medals so that the shooting performance is within an appropriate numerical range. In particular, the difference in the probability of winning a bonus role that gives a big profit to a player greatly affects the ratio between the number of medals inserted by the player and the number of medals paid out to the player (hereinafter referred to as the payout rate) These setting values can be set by an employee by operating setting means for each gaming machine, and selecting one setting value from among six setting levels, for example.

However, in the above conventional gaming machine, when the bonus game is won and the game is shifted to the special game, the game configuration of the bonus game is determined. There is a problem that the game purpose is only to obtain the expected medal payout, and the game itself becomes monotonous. In order to solve such a problem, a gaming machine has been invented in which a small role game in a BB game has technical intervention. However, in the above invention, since the small game in the BB is targeted, the same problem that the game becomes monotonous when a BB game is not provided, or when a single RB game occurs, etc. Will be inherent.

A plurality of reel stop means for individually stopping the reels, a lottery means for lottery for each game, and an internal winning combination setting for setting the ratio of the internal winning combination determined by the lottery means in a plurality of stages And a game control means for stopping and controlling the plurality of reels according to the lottery result of the lottery means,
In the gaming machine having a special game state different from the normal game state, the game control means shifts when a predetermined symbol combination stops at a predetermined winning line as a result of the lottery,
The special game has a plurality of predetermined winning combinations, at least one of the predetermined winning combinations has a maximum payout number, and at least one other winning combination has a minimum payout number. It is characterized by.

  In the above gaming machine, one of the conditions for the special game is that the specified number of games has been reached, the winning combination set as the maximum payout number is won at a rate of 2/3, and the minimum payout number It is set to win the winning combination set to 1/3 at a rate.

  Further, the special game has one of the ending conditions that the specified number of winnings has been reached, and the winning combination set to the minimum payout number is determined by the plurality of reel stop means until the specified number of winnings is reached. In accordance with at least one stop operation timing, the winning line can be arbitrarily selected with the winning line set as the minimum payout number.

  Further, the present invention is characterized by comprising display means capable of displaying at a predetermined notification timing the number of winning winning combinations set as the maximum payout number and whether or not to win.

  By adopting such a configuration, during the RB game, the player will play the game while always taking into consideration the number of games of the RB game and the number of winnings of at least two types of bonuses. You can give a sense of tension to the game.

  In addition, according to this configuration, it is possible to win more medals by winning as many as possible prizes in the RB game without winning prizes with less prizes (for example, eight times). Since it can be acquired, the player can enjoy the pleasure of selecting whether or not to win according to the type of the winning combination. Furthermore, since at least one accessory can be stopped on or off the winning line according to the operation timing of the stop button of at least one reel, it can be arbitrarily determined depending on the player's technique. It is possible to realize an RB game with technical intervention that allows selection of whether or not a prize is won.

  The CPU 36 calls out necessary data from the fixed data stored in the ROM according to the progress of the game, and also gaming machines based on input / output signals from each peripheral device connected to the input / output port. Is controlling the operation.

  Next, an outline of the game method of the present invention will be described. The player inserts a medal from the medal insertion slot 3 or, if there is a credited medal on the credit display unit 20, operates the BET switch 49 to arbitrarily determine the number of medals to be inserted. The winning line is activated according to the number of inserted medals, and the game is started by operating the start lever 12. When the start lever 12 is operated, the reels 4 to 6 start to rotate sequentially, and the player operates the stop buttons 13 to 15 corresponding to the reels to stop the rotation of the reels. Normally, as a result of an internal lottery performed after the star lever operation, when a predetermined winning combination (also referred to as an accessory) is won and all reels are stopped, a specific symbol follows any of the five winning lines. Winning is awarded when all of them are arranged. The combination corresponding to the type of symbol combination is determined in advance, and medals are paid out according to the combination.

  When the combination of symbols stopped on the winning line is a regular bonus (RB) symbol, the game can be shifted to RB game, and further increase in payout can be expected. In the RB game, a total of 12 games can be executed, and during this time, a symbol combination of a predetermined character is generated with a high probability. Of the 12 games, the RB game ends when a predetermined prize is won 8 times. In the case of a small role symbol, since the flag is not carried over, a predetermined payout is made only when each symbol can be stopped in the game, and the game ends. In the case of replay symbols, the game can be started again without inserting medals.

  In this embodiment, only a single RB game is set as a special game, but a BB game can also be provided. The BB game is a special game configured with a set of the RB game and a game called a BB medium general game (or a small role game) that acquires a small role that occurs with high probability during the BB game. Yes, when the number of games of general games in BB and the number of transitions of RB games in BB reach the upper limit (for example, 30 times and 3 times, respectively), or the number of medals acquired during BB games is the upper limit (for example, The process ends when the number reaches 400).

  The result of the internal lottery of the winning combination is notified to the player in a plurality of notification forms. One of them is a reach eye notice. A reach eye is a symbol combination (outgoing) in which the reels are controlled so that they only appear when a bonus flag is established. There are more than 100 types. A skilled player can instantly determine the internal winning of the bonus flag by learning this reach.

  As another notification form, a display means for notifying the player with visual, auditory, and tactile sensations is provided so that the player can easily determine whether there is an internal winning. For example, the upper lamp 16, the side lamp 18, the reel backlight 29, a dedicated notification lamp (not shown), etc. are turned on and blinked, a specific sound is output from the speaker 11, and a liquid crystal display is displayed. A device 17 or the like is provided for effect display. Further, when the reels 4 to 6 stop rotating, they can be controlled so as to stop by an operation different from the normal rotation, for example, reverse rotation or vibration. Further, by combining these various means, it is possible to notify the player of the occurrence of the internal winning of the winning combination with different probabilities. For example, when a dedicated notification lamp is lit, the player is informed that a predetermined winning combination has been won internally with a probability of 100%, and, for example, a flashing pattern of a reel backlight and output from a speaker. Depending on the combination of game sounds, it is also possible to display a pseudo effect that a predetermined winning combination may be 100% internally won or may not be internally won (gasse).

  Furthermore, the liquid crystal display device selects one or a combination of a plurality of patterns based on a predetermined selection condition from among a plurality of effect patterns using moving images. Can be displayed.

  FIG. 4 is a diagram conceptually showing a lottery probability table according to the gaming machine of the present invention. Originally, in this embodiment, there are a normal game and an RB game as the gaming state, and the winning combination in each gaming state, the number of payouts at the time of winning, and the internal lottery probability of each winning combination are illustrated. In a normal game, five types of symbol combinations are subject to lottery. When the RB combination is won and a prize is won, the number of medals is 0, but after that, the RB game can be entered, and the internal lottery probability is set to 1/80. In the following, a small combination A, a small combination B, a small combination C, and a replay are set as illustrated.

  On the other hand, in the RB game, the RB combination is not randomly drawn, and only the small combination A, the small combination B, and the small combination C are generated with higher probability than in the normal game. The small combination A and the small combination B each have 15 medals paid out at the time of winning, and the payout for the small combination C is set to one. The set value of these internal lottery probabilities is that a small role A or a small role B is generated with a probability of about 2/3 out of 12 prescribed RB games, and a small role C is generated with a probability of the remaining 1/3. It has been adjusted to occur.

  Therefore, after the transition to RB gaming, out of all 12 RB games, up to 4 games, for example, even if a small role C with only one payout wins, , And play the game to win the small role A or the small role B with 15 payouts in the remaining 8 games, thereby effectively utilizing the 8 winning chances stipulated in the RB game Can do.

  Note that the lottery probability table is provided corresponding to the number of medals bet, the six set values, and the gaming state, respectively, so that the corresponding probability lottery table is selected according to the situation, and the game proceeds. It has become.

  FIG. 5 is a diagram illustrating a reel symbol table. Originally, a code number is arranged on the left side of the reel symbol table, and numbers corresponding to 21 symbols are assigned to the left reel, the middle reel, and the right reel, respectively. When the reels stop rotating, the main control unit determines which symbols are stopped on the winning line with reference to this table. In this figure, in order to make the explanation easy to understand, only symbols necessary for explanation are represented by symbol images, and other symbols are omitted and left blank.

  (A) illustrates a case where a cherry symbol is assumed as a small combination C in which a single medal is paid out at the time of winning in an RB game. On the left reel, cherries are arranged in the seventh (code number 6) and the 19th (code number 18). For this reason, when a cherry is won during the RB game, the player operates the stop button so that the two cherries on the left reel do not stop on the winning line.

  Since the reel is normally controlled to pull in 4 frames, it is necessary to operate the stop button when the rotating cherry is at a position 5 frames or more away from the winning line. In this embodiment, since two cherries are arranged on the left reel, the safest operation position of the stop button that does not draw any of these two cherries is between the two cherries. The proper operating position is that the lower cherry (code number 18) passes over the winning line, and the upper cherry (code number 6) is 5 or more frames away from the winning line. At a certain timing.

  The figure (b) is a figure that is easy for the player to visually recognize, for example, “Red 7” at the appropriate position as the stop button operation timing for removing one small part C (cherry) in the figure (a). Are arranged in succession. This makes it easier for the player to operate the stop button to remove one small role (cherry), and in the RB game, wins the maximum number of medals by winning 15 small roles as much as possible. Can expect to enjoy the game. Note that the symbol set as one small combination is not limited to the cherry symbol, and the reels to be arranged and the code positions and the number of each reel are not limited to these symbols.

  With reference to FIG. 6, the main game operation in the present embodiment will be described. The main game refers to one game that is operated by operating a gaming machine. One game is from the operation of the start lever to the stop of the three reels, and further, the insertion of medals performed when the game is executed. It is assumed that additional operations and processing until transition to a gaming state other than the normal gaming state, such as operation, setting of the bet number of medals, winning determination, and medal payout processing, are included.

  When the gaming machine is turned on, a re-game automatic turning-on process is executed (step 101). After the interruption process is permitted once (step 102), the game medal is checked for turning on (step 103), and a checking button is checked (step 103). Step 104), checkout button check (step 105), setting key check (step 106), and start lever check (step 107) are executed. Next, it is determined whether the start lever has been operated by the player (step 108). If no, the process returns to step 102. If yes, a medal insertion signal is transmitted to the game control board (step 109). A setting process at the start of the game is executed (step 110). Thereafter, a probability lottery process is performed (step 111). When a winning combination is won, an internal winning flag of the winning combination is stored in a predetermined area on the RAM, and then a reel rotation process is performed (step 111). 112). When a certain period of time has elapsed since the reel started to rotate, the player can operate the reel stop button. When the player operates the reel stop button, the gaming machine executes a reel stop process (step 113). ) Specifically, in the reel stop process, the reel rotation process is continued until the reel stop button is operated. On the other hand, if the reel stop button is not operated even after a predetermined time has elapsed from the start of the reel rotation, the reel stop process is automatically stopped. Processing is executed. Thereafter, a winning determination process is executed in accordance with the stopped symbol combination (step 114).

  Next, with reference to FIG. 7, details of the winning determination process when the combination of the stopped symbols is a winning combination will be described. When the symbols are stopped on the winning line, the result of the lottery process is an internal winning, and no winning is generated even if the winning flag is set (the predetermined internal winning symbols are not aligned on the winning line). ) There are cases. That is, the reel stop control is not mechanically performed, but is influenced by the operation timing of each stop button of the player. This is because, for example, when the reels are stopped, four frames are pulled in, and if there are no specific winning symbols in the four frames, the winning symbols are not aligned.

  In the winning determination, with reference to a winning symbol combination table (not shown), it is first determined whether the combination of symbols stopped on the winning line is an RB symbol (step 115). In the case of Yes, it progresses to FIG. 8 and performs the process of RB game. In the case of No, next, it is sequentially determined whether each symbol is A, B or C (steps 116 to 118). If any of the symbols of small roles A, B, and C is stopped, the internal winning flag is canceled (steps 119, 121, or 123), and the corresponding number of medals is paid out ( Step 120, 122, or 124). If it is determined that it is not any of the small role symbols, then it is determined that it is a replay symbol (step 125). In the case of Yes, it is possible to cancel the internal winning flag, return to the main game of FIG. 6, and replay one game without betting medals. In the case of No, it means that the winning symbol of any winning combination could not be stopped on the winning line (losing), the internal winning flag is canceled, and the determination process is terminated.

In step 127, if the RB has been internally won, it can be carried over until the RB internal winning flag is won, so that it is stored as it is in a predetermined area on the RAM. Is the same.

  With reference to FIG. 8, the process performed in the RB game after winning the RB symbol will be described. Based on the winning determination of the RB symbol, an RB generation command is transmitted to the game control unit of the CPU (S201), and has a function of notifying the player of the internal winning of RB to the player by the display device 17 or other display means. If so, the display is cleared (S202). Next, as data for RB winning, 12 is set as the predetermined number of RB games in the RB game counter, and 8 is set as the winning limit number in the RB bonus winning counter (S203). Subsequently, an RB generation signal is transmitted to the concentrated terminal board (S204), an RB state flag is set in a predetermined area of the RAM (S205), and an RB game lottery probability table is set (S206).

  Since the RB game is performed by betting one medal, the player inserts one medal and operates the start lever to start the RB game. Almost simultaneously, a lottery process is performed with reference to the RB game lottery probability table (S207), and a reel rotation process (S208) is performed. When the reels stop, a determination process during the RB game is performed based on the combination of the stopped symbols.

  In the determination process, it is first determined whether or not a single combination is won out of the combinations in the RB game of this embodiment (S209). In the case of Yes, it is determined whether or not the value obtained by subtracting the value of the RB prize winning counter from the value of the RB game counter is 0 (S210). Display processing is executed (S211), and when 1 to 4 other than 0 is calculated, one piece of unusable display processing (S212) is performed, and if No in S209, Since the 15 winning combination is either winning or losing, the process according to the lottery result is executed (S213), and then the reel stop process (S214) is executed according to the timing of the player's reel stop button operation. The

  Next, it is determined whether or not a winning combination of symbols has been won (S215). If a prize has been won, 1 is subtracted from the RB bonus winning counter (S216), and then it is determined whether the RB bonus winning counter = 0 (S217). If the number is less than 8, the RB game counter is decremented by 1 (S218), and then RB game counter = 0 is determined (S219). In No, it returns to S206 in order to perform the remaining RB game, and the same operation as described above is repeated.

As a result of the determination in S217, when the number of winnings of the RB bonus has reached the prescribed number of 8 times, and when the number of games in the RB game has exhausted the prescribed 12 times in S219, an RB end command is transmitted ( After the RB state flag is reset (S221), the RB end time data is set (S222), the RB end signal is transmitted to the concentrated terminal board (S223), and the processing of the RB game ends.

  The series of processes in S209 to S219 described above will be described in more detail. In the RB game, the number of RB games is defined as 12 times, of which 8 winnings are possible, so that 12−8 = 4 times can afford to select a winning combination. In other words, if the first internal RB game is won in the first RB game, 12-8 = 4, if the first RB game is won in the second RB game, 11-8 = 3, the first in the third RB game. 10-8 = 2, the first win in the fourth RB game is 9-8 = 1, and 8-8 = 0 in the fifth RB game. Therefore, from the 1st RB game to the 4th RB game, if you remove the winning items from the inside and do not win, the remaining RB games will be 8 from the 5th and subsequent RB games. If you don't get a prize in this game, you won't be able to win medals. Similarly, if there is one win in the first 4 RB games, in order to get all the remaining 7 wins, if you remove the bonus in the 5th RB game, Since 7-7 = 0 in the RB game, it is necessary to win all seven RB games after the sixth.

  In the present embodiment, in order to make it possible to win 15 winning combinations as much as possible with respect to the specified number of winnings of 8 winning combinations, 15 winning combinations are won in the determination process. In this case, the player can win a 15-card combination by operating the stop button as usual, while the single-player combination is won and there is a margin in the number of RB games, that is, an RB game. If the value of 1 to 4 other than 0 is calculated as a result of subtracting the value of the RB winning prize winning counter from the value of the counter, stop the reel so that the symbol of one piece does not stop on the winning line By operating the button and further displaying a notice to stop the reel by removing one winning combination, as many as 15 winning combinations are won out of the specified number of 8 winning combinations. Can be Characterized in that the so that.

  In the present embodiment, the number of RB games and the number of winning prizes for RB games are defined as 12 times and 8 times, respectively, but the specified number of times is not limited to these.

  Further, in this embodiment, the ratio of the lottery probabilities of the 1 small bonus and 15 small bonuses in the RB game is set to 1/3 and 2/3, respectively. It is not limited to this value.

  In addition, the types of bonuses in the RB game and the number of payouts corresponding to the bonuses are not limited to the numerical values exemplified in the present embodiment.
