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, and the symbols arranged on the outer periphery are players during the game. Is illuminated from the back by a lamp or LED (hereinafter referred to as a backlight) provided inside each reel so that the symbols can be easily seen.

  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 looking at the symbols to be 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 can be arranged on the valid winning line and the winning combination can be won, 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 is lost.

  The winning combination (also referred to as an accessory) corresponding to the type of symbol combination is determined in advance, and if those symbols are stopped on the winning line and can be won, the payout is made according to the combination. Is 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.

  Furthermore, there is a specific gaming state that is different from the special gaming state and occurs with a predetermined probability when a predetermined disclosure condition is satisfied. As this specific gaming state, for example, CT (challenge time), a medal or a credit bet bet on which at least one reel out of a plurality of reels is uncontrolled and the reel is stopped according to the operation timing of the player's stop button. The replay game that can start the next game can be continuously executed a predetermined number of times or until other predetermined end conditions are satisfied, and the replay winning probability is set higher than the winning probability in the normal gaming state. There is what is called RT (Replay Time).

  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 a setting means for each gaming machine, and selecting one setting value from among six setting levels, for example.

Japanese Patent Application Laid-Open No. 2003-299776 discloses a technique for shifting to the ART mode when a BB is won in a game in the normal mode and the BB is carried over without winning a prize.
However, when the RT mode start condition is a bonus combination winning as in the above-described prior art, the probability of entering the RT mode is limited by the bonus combination drawing probability. Since the probability of occurrence of a normal bonus combination is kept low, there is a problem that it is difficult to shift to the RT mode, and the game so far becomes monotonous.
Japanese Patent Laid-Open No. 2003-299776

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a more interesting gaming machine by improving the probability of transition to a specific gaming state during normal gaming.

In the normal game state, when a special small combination corresponding to at least one small combination is won among the plurality of winning combinations selected by the first lottery means, the second lottery means and the winning line forming means, A special small part winning line selection means for specifying at least one winning line among the plurality of winning lines is provided.

  The symbol combination of the special small role appears in the normal gaming state at the same time as the symbol combination of the specific game transition symbol that shifts to the specific game state or alone.

  The special winning combination winning line selection means includes a case where the special winning combination occurs alone and a case where a combination of the special winning combination and the specific game transition symbol appears at the same time, out of all 5 winning lines. The predetermined number is associated with each other and divided into two groups, and any one of the groups is selected by the second lottery means.

  The winning line forming unit is configured to stop and control a predetermined reel among the plurality of reels so that the combination of the special small role symbols appears in the form of a winning line determined by the second lottery unit. It is characterized by.

  In the case where the combination of the specific game transition symbol and the symbol combination of the special bonus combination occur at the same time, the symbol combination of the special bonus symbol is a horizontal or straight line in the middle or lower row of the plurality of winning lines. It is set to stop at either.

  In the case where the symbol combination of the special small role appears alone, it is set so as to stop at any one of the plurality of pay lines in the upper horizontal line, the right-up diagonal line, or the right-down diagonal line. It is characterized by being.

  Of the symbols drawn on each reel, the symbols constituting the combination of at least one of the specific game transition symbols and the at least one special small role symbol are arranged in succession, and each one of them A plurality of sets are arranged at a predetermined interval.

  With such a configuration, during a normal game, a winning combination associated with at least one special small combination among a plurality of winning combinations can be won internally and awarded on a predetermined winning line. In this case, the combination of the specific game transition symbols that can be transferred to the RT game in the specific game state will always stop on the predetermined winning line at the same time, in addition to paying out medals by winning the small role, It is possible to provide a gaming machine having a dual privilege of being able to shift to a specific game.

  In addition, it is determined by lottery whether a special small role is generated at the same time as a combination of specific game transition symbols or only by a single game. In some cases, it is possible to enjoy the game while predicting which case it is.

  Furthermore, when a special small role is elected, the player may decide whether the special small role will stop at the top, middle, or bottom of the first reel, whether the special small role is a single prize, or a specific game It can be expected and expected to some extent whether the combination of transition symbols will appear at the same time. Compared with conventional game machines, the expectation for the small role winning can be enhanced, and the amusement game can be realized.

  Further, the CPU 36 calls necessary data from the fixed data stored in the ROM according to the progress of the game, and based on input / output signals from peripheral devices connected to the input / output ports. It controls the operation of gaming machines.

  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 rotating sequentially, and the player operates the stop buttons 13 to 15 corresponding to the reels to stop the rotation of the reels. Usually, a random number is sampled by the lottery processing unit 40 after the star lever operation. As a result of this internal lottery, if a predetermined winning combination (also referred to as an accessory) is won and a specific symbol is aligned along one of the five winning lines when all reels are stopped, Become. 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.

  Further, when the combination of symbols stopped on the winning line is a big bonus (BB) symbol, the game can be shifted to a BB game. 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).

  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.

  Furthermore, when a combination of specific game transition symbols is prepared, it is possible to shift to a specific game RT (replay time) game. In RT game, the winning probability of a replay symbol that can play one game without betting medals is set higher than that in the normal gaming state, and a predetermined number of games (for example, 10, 50, 100, etc.) When the game is digested, the game ends, and the player can continue to play the game while suppressing the decrease in consumption medals, and in the meantime, the player can expect to win a winning combination.

  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 illustrating a reel design tape. Originally, the reel symbol tape has a symbol number on the left side, and the left reel, the middle reel, and the right reel have numbers corresponding to 21 symbols, 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.

  In this embodiment, “bell” is set as the special small role symbol, and “JAC”, “JAC”, and “cherry” are set as the symbols constituting the combination of the RT game transition symbols that are specific games. The feature of each reel of the left reel, middle reel, and right reel is that one special small role symbol and one RT game transition symbol are arranged continuously with each other, and each successive set is A plurality of sets are arranged at predetermined intervals.

  More specifically, in the left reel, “JAC” and “Bell” are consecutively arranged at intervals of 2 to 4 frames, in the middle reel “JAC” and “Bell”, and in the right reel “Cherry” ”And“ Bell ”are consecutive and are arranged at intervals of 1 to 3 frames. Therefore, if the stop button corresponding to each reel is operated at an appropriate timing, the “bell” can be stopped on any winning line, and the RT game transition pattern arranged immediately above the “bell”. "JAC" or "Cherry" is also pulled in and stops in the symbol display area immediately above "Bell".

  With reference to FIG. 5, the stop pattern of “Bell” at the time of winning the special small role in this embodiment will be described. (A), (d), and (e) of FIG. 5 have illustrated the stop pattern in case the combination of "bell" occurs independently. (A) is on the upper horizontal line of the symbol display area, (d) is on the upper right line, and (e) is on the lower right line. The symbols are all in a stopped state, indicating that the small role bell has won a prize.

  In (b) and (c) of FIG. 5, “bells” are stopped in a row in the middle horizontal direction and the lower horizontal direction of the two winning lines and the symbol display area, and each “bell” is stopped. "JAC", "JAC", and "Cherry" are displayed on the upper line of the winning line. Therefore, the small role bell wins, and a medal corresponding to the small role bell is paid out, and the game can be shifted to RT game.

  With reference to FIG.6 and FIG.7, the stop control method of a bell symbol at the time of internal winning of a special small role (bell) is demonstrated. After the internal winning of the bell, in order to determine the winning line of the bell symbol, the second lottery table (first reel stop table) of FIG. 6 and the winning line selection table of FIG. 7 (second and third reel stop table) Is referenced. In the left column of each table, numbers 0 to 20 are written as symbol numbers. These numbers correspond to symbol numbers given on the left side of the reel symbol tape in FIG. The symbol numbers located at the lower part of the reel display area when the button is pressed are shown.

  The second lottery table has two tables, table A and table B. Table A has a random value range of 14 to 128, and table B is assigned a random number of 1 to 13. Yes. Depending on which random number value is selected among these random number values, either Table A or Table B is selected, and a winning line on which the bell symbol is controlled to be stopped is determined.

  Further, in the second lottery table, the number of sliding symbols and the winning line selection table to be referred to during the second and third reel stop control are set in Table A and Table B, respectively, corresponding to each symbol number. ing. Here, the sliding piece represents the number of frames that are controlled to move from the symbol at the position where the reel stop button is pressed down to the symbol that actually stops.

  Five types of winning line selection tables are prepared, and Table 1 and Table 3 correspond to Table B. In order to make a combination of a special small role symbol and a combination of specific game transition symbols appear at the same time, a special small role symbol is displayed. Are set to be stop-controllable on the middle or lower winning line, respectively.

  On the other hand, Tables 2, 4, and 5 correspond to Table A, and the special small role symbol combination is a stop pattern in which only a single combination is displayed. It is set to stop control the role symbol.

  In addition, the number “1” written in the frames of the second reel and the third reel of the tables 1 to 5 controls the drawing in which the symbol in which “1” of each reel is written is drawn in the lower part of the symbol display area. The symbol position to be performed is shown. The second lottery table includes a function as a second lottery means, and the winning line selection table includes a function as a winning line forming means, and constitutes a special small part winning line selecting means.

  In the present embodiment, the details will be described by taking as an example a case where the reel stop button is pressed by forward pressing (in order of the stop button for the left reel, the stop button for the middle reel, and the stop button for the right reel). For example, in the first lottery, a special small role bell is won internally, and in the second lottery, a random number 30 is extracted. The symbol number 16 is displayed in the lower part of the symbol display area of the first reel, and the symbol display area of the second reel is displayed. Assuming that the stop button is pressed at a timing such that symbol number 15 is located in the lower row and symbol number 4 is located in the lower row of the symbol display area of the third reel, table A including random number 30 is first selected. Then, since the symbol number 16 is located in the lower part of the symbol display area of the first reel (left reel), the number of sliding symbols is referred to by referring to the number of sliding symbols corresponding to the symbol number 16 and the winning line selection table. 1 frame and table 2 are selected.

  First, the left reel, which is the first reel, slides the symbol number 16 by one frame and the symbol number 15 is controlled to stop at the lower stage of the symbol display area of the first reel. "Is stopped and displayed. Next, stop control of the middle reel as the second reel and the right reel as the third reel is sequentially executed with reference to the table 2. In the control of the second reel, the symbol number 11 has the number “1” closest to the symbol number 15 located in the lower stage of the symbol display area of the second reel. Therefore, the symbol number 11 is the symbol display of the second reel. Slide 4 frames to the bottom of the area and stop by pulling in. Accordingly, the “bell” is stopped and displayed on the upper stage of the symbol display area of the second reel. Similarly, for the third reel, the stop button is pressed at the timing when the symbol number 4 is positioned at the lower stage, and since the number “1” is set in the third reel of the table 2, the symbol number 4 remains as it is. Will be stopped and displayed at the bottom. Accordingly, the “bell” also stops at the upper stage of the symbol display area of the third reel, so that the upper “bell” is aligned, and a single small role bell win is realized.

  With reference to FIG. 8, 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 1). After the interruption process is permitted once (step 2), a gaming medal is checked for turning on (step 3), and a checking button check ( Step 4), settlement button check (step 5), setting key check (step 6), and start lever check (step 7) are executed. Next, it is determined whether the start lever has been operated by the player (step 8). If no, the process returns to step 2, and if yes, a medal insertion signal is transmitted to the game control board (step 9). A setting process at the start of the game is executed (step 10). Thereafter, a probability lottery process is performed (step 11). 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 executed (step 11). 12). 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 13). ) 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 14).

  With reference to FIG. 9, the winning line selection control when the special small combination is won during the main game in this embodiment will be described. First, as shown in FIG. 8, when the player starts a normal game (step 101), the winning determination of each accessory is sequentially executed in the first probability lottery of step 11 of FIG. Here, it is determined whether or not the bell set as the specific winning combination is won (step 102). If No, the winning determination of other bonuses, reel rotation, and stop processing are performed according to the normal game processing. After that, a winning determination corresponding to the stopped symbol combination is made, and a medal payout, a transition process to a special game state, and the like are executed. In the case of Yes, the second probability lottery is performed (step 103). The second probability lottery is executed with reference to a dedicated lottery table (not shown) having a random value range 1-128. In this embodiment, the random number values 1 to 13 are selected from the table B, and the random number values 14 to 128 are selected from the table A (step 104).

  Next, the operation timing of each reel stop button pressed by the player is determined (step 105). First, when the first reel stop button is pressed, based on the symbol number located in the lower part of the symbol display area of the first reel, the number of sliding symbols set corresponding to the symbol number, Among the payline selection tables for controlling the stop position of the third reel, one of the tables 1 to 5 is acquired (steps 106 and 107), and the stop control of the first reel is executed (step 108).

  Next, referring to one of the payline selection tables selected in step 107, stop control of the second reel and the third reel is performed. The number of frames from the position of the symbol number located in the lower part of the symbol display area to the drawing target symbol at the nearest position is calculated for each reel, and the number of sliding symbols on each reel is determined (step 109). Each reel is slid and stopped by the number of sliding pieces (step 110).

  In this embodiment, when the bell symbols are stopped on the middle and lower winning lines together, the case where the symbol combination of the specific game that shifts to the RT game is also stopped is described. However, the symbol combination of the specific game is stopped. However, the present invention is not limited to this. For example, depending on the timing of pressing the stop button of each reel, the combination of symbols of a specific game can be stopped independently regardless of the winning or winning prize of the special small role. There is also a case.

  Further, the symbols set as winning combinations are not limited to JAC symbols, cherry symbols, and bell symbols, and the positions and arrangement intervals of the reels are not limited to these.

  Further, the operation order of the stop buttons is not limited to forward pressing, and any of the three stop buttons may be operated.

  Furthermore, in the present embodiment, the case where the bell symbol is stopped and all the buttons are pressed in order is described. However, for example, when the table A and the table B are selected, the operation order of the stop button is changed. It is also possible to notify the stop button operation order and the winning line as appropriate.

  In this embodiment, when a special small combination is won, all reels are controlled to cause slipping, but the target of slip control is not limited to all reels. For example, when a predetermined condition is satisfied, it is possible to make at least one reel uncontrollable and win a special small role symbol according to the skill of the player.
