Description

  The present invention relates to a slot machine.

  A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, the winning is generally determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize group will be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or a plurality of roles and corresponds to a lottery category. That is, a prize group and a combination may correspond one-to-one, or a plurality of combinations may correspond to one prize group.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid pay line, the reel stop timing is delayed, The reel is controlled so that the symbols constituting the winning combination do not stop on the valid winning line. The same applies to the combination corresponding to the prize that was not won in the internal lottery. Such control is called kick control. On the other hand, if a prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line. Winning any prize group in the internal lottery is called winning, and not winning any prize group is called losing. And, the fact that the symbols stopped on the winning line make up the winning combination is called winning, and the non-winning is not forming the winning combination. In non-winning cases, when the internal lottery result is lost, even if the internal lottery is won, the operation timing of the reel stop button is greatly shifted, so that the role corresponding to the winning prize is not established, so-called Includes missing items.

  Such a slot machine can execute a plurality of types of games such as a big bonus game and a regular bonus game in addition to the normal game. The expected value of the number of medals that can be acquired per game is larger in the big bonus game and the regular bonus game than in the normal game. The transition from the normal game to the big bonus game is conditional on winning the BB prize, and the transition to the regular bonus game is conditional on winning the RB prize. The internal lottery described above is executed for each game, and the internal lottery result is usually not carried over to the next game. Carry over to the game.

  As described above, winning a prize is a necessary condition that the prize is won by an internal lottery, and further, it is necessary and sufficient to operate a reel stop button at a predetermined timing. However, there is known a slot machine capable of executing a special game that does not require an internal lottery for winning (Patent Document 1). In this type of special game, the reels are stopped regardless of the result of the internal lottery. That is, the kicking control described above is not executed. Therefore, if the player operates the reel stop button accurately aiming at a desired symbol, a prize is won.

Japanese Patent Publication No. 5-74391

  By the way, in the slot machine that employs the special game described above, the reel is stopped regardless of the result of the internal lottery, and so-called pull-in control is not executed. However, skill is required to recognize the symbol displayed on the reel rotating at high speed and press the reel stop button at the timing when the desired symbol is reached. Moreover, it is difficult to accurately operate the reel stop buttons for all three reels unless the player's skill is considerably high. Therefore, most players have a problem that they cannot enjoy special games.

  In particular, at the time when the first stop operation and the second stop operation are completed, if there are no symbols that make up the winning combination on the activated pay line, it is not necessary to wait for the last stop operation, and it is not won However, there was a problem that the special game at the corner turned up instead. There was also a demand to simplify the hardware required for special games.

  In addition, in the conventional slot machine, there is a machine that executes a predetermined number of special games, but there is no known machine that reflects a player's skill in the number of consecutive special games.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a slot machine that improves the taste of a special game.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The slot machine according to the present invention includes a management means (31) for switching various games including a first game and a second game according to a predetermined condition and generating management information indicating a game type, and a plurality of special symbols. A plurality of display columns (R1, R2, R3) that cyclically variably display types of symbols, and the plurality of displays in a state where variable display of the plurality of display columns (R1, R2, R3) is stopped Among the plurality of pay lines (L1 to L5) crossing the row (R1, R2, R3), any of the cases where the arrangement of symbols stopped on the activated pay lines (L1 to L5) is in a predetermined mode In a slot machine for winning a prize and paying out a game medium corresponding to the winning prize, the slot machine is provided corresponding to each of the plurality of display columns (R1, R2, R3), and stops upon detecting a player's stop operation. A plurality of stop operation means (7a, 7b, 7c) for outputting the work signals (44a to 46a) and a lottery are performed to determine one of a plurality of prizes and loses and to indicate a winning prize or a loss When the lottery means (31-33) for generating lottery information (ISD) and the management information indicate the first game, the lottery information (44a-46a) is detected at the timing when the stop operation signal (44a-46a) is detected. If the symbol constituting the winning prize indicated by (ISD) is within a predetermined number of moving symbols from the activated winning line (L1 to L5), the activated winning line (L1 to L5) The plurality of display rows (R1, R2, R3) are controlled to be pulled up and stopped, and when the management information indicates the second game, the stop operation signal (44a to 46a) is detected. Taimi When the special symbol is within the range of the predetermined number of moving symbols from the activated winning line (L1 to L5), the special symbol is placed on the activated winning line (L1 to L5). The timing at which a part of the display columns (R1, R2, R3) among the plurality of display columns (R1, R2, R3) is controlled to be pulled in and stopped and the stop operation signal (44a to 46a) is detected. In order to stop the symbols separated from the activated winning line (L1 to L5) by the number of moving symbols less than the predetermined number of moving symbols on the activated winning line (L1 to L5) Stop control means (31) for controlling the other display columns (R1, R2, R3) among the display columns (R1, R2, R3).

According to the present invention, in the first game, the pull-in control is executed according to the winning prize indicated by the lottery information, while in the second game, the winning line (L1 to L5) in which the special symbols are activated for a part of the display columns. In other display columns, the symbols are shifted and stopped by the number of moving symbols smaller than that of some display columns. Therefore, for other display columns, the player can operate the stop operation means aiming at a predetermined symbol. That is, in the second game in which the kicking control is not performed, the player does not need to make a push for all the display columns, and can win a prize by making a push for only the other display row. As a result, even the player with low skill can enjoy the second game. For example, the first game may correspond to a normal game and a CB game, the second game may correspond to an FB game, and the special symbol may be a plum symbol.
In addition to the mechanical reels, the display columns include those displayed electronically on the display device.

  Further, another slot machine according to the present invention includes a managing means (31) for switching various games including the first game and the second game according to a predetermined condition and generating management information indicating the type of the game, A plurality of display columns (R1, R2, R3) that cyclically variably display a plurality of types of symbols including symbols, and in a state where variable display of the plurality of display columns (R1, R2, R3) is stopped, Among the plurality of winning lines (L1 to L5) crossing the plurality of display columns (R1, R2, and R3), the arrangement of symbols stopped on the activated winning lines (L1 to L5) is a predetermined mode. In a slot machine that wins one of the prizes and pays out the game media corresponding to the prize that is won, the slot machine is provided corresponding to each of the plurality of display columns (R1, R2, R3), and detects a player's stop operation. A plurality of stop operation means (7a, 7b, 7c) for outputting stop operation signals (44a to 46a) and a lottery to determine one of a plurality of prizes and loses, When the lottery means (31-33) for generating lottery information (ISD) indicating a loss and the management information indicates the first game, at the timing when the stop operation signal (44a-46a) is detected, When the symbol constituting the winning prize indicated by the lottery information (ISD) is within the predetermined number of moving symbols from the activated winning line (L1 to L5), the symbol becomes the activated winning line (L1). ~ L5) When the plurality of display rows (R1, R2, R3) are controlled to be pulled up and stopped, the management information indicates the second game, and a predetermined condition is satisfied, Stop operation signal (44a to 46a) When the special symbol is within the predetermined number of moving symbols from the validated winning line (L1 to L5) at the timing when (44a to 46a) is detected, the special symbol is the validated winning. In addition to controlling some display columns (R1, R2, R3) among the plurality of display columns (R1, R2, R3) so as to be drawn and stopped on the lines (L1 to L5), the stop operation signal ( 44a to 46a) at the timing when the activated winning line (L1 to L5) is separated from the activated winning line (L1 to L5) by the number of moving symbols less than the predetermined moving symbol number, the activated winning line (L1 to L5). Stop control means (31) for controlling the other display rows (R1, R2, R3) among the plurality of display rows (R1, R2, R3) so as to be stopped upward. It is a sign. This slot machine executes stop control peculiar when the game is the second game and a predetermined condition is satisfied. Here, the predetermined condition includes operating the stop operation means in a predetermined order. In this case, the stop control means is provided with an operation order detection means for detecting a stop operation based on the stop operation signal, and the predetermined condition is satisfied when the detected operation order matches a predetermined operation order. It may be determined that it has been done.

  In the slot machine described above, the number of movement symbols less than the predetermined number of movement symbols is zero, and the stop control means (31) detects the activated winning line at the timing when the stop operation signal (44a to 46a) is detected. It is preferable to control the other display columns (R1, R2, R3) so as to stop the symbol closest to (L1 to L5) on the activated pay line (L1 to L5). In this case, in other display columns, so-called bitter stop control is performed. Note that the closest symbol is a symbol before the winning line is reached by rotation of the display row, except for symbols that have gone too far from the winning line. That is, the number of moving symbols of zero means not only that the symbol stops when the stop operation is performed, but also that the center position of the symbol overlaps the winning line by moving within a range of less than one symbol from the moment when the stop operation is performed. . Specifically, as shown in FIG. 43 (A), when the center position Q of the plum symbol is before the activated pay line L1 when the reel stop button is operated, the plum symbol The reel rotates and stops so that the center position Q overlaps the activated pay line L1. On the other hand, when the reel stop button is operated as shown in FIG. 4B, if the center position Q of the plum symbol has gone too far from the activated pay line L1, the bell symbol which is the next symbol is displayed. The reel rotates and stops so as to stop at the winning line L1 for which is enabled.

  In the slot machine described above, the award includes a predetermined award composed of the special symbol, and the stop control means (31) indicates that the management information indicates the first game and the lottery information (ISD ) Is a predetermined prize, and at the timing when the stop operation signal (44a to 46a) is detected, the special symbol is moved from the activated winning line (L1 to L5) to the predetermined movement symbol. The plurality of display columns (R1, R2, R3) are controlled so that the special symbols are drawn onto the activated pay lines (L1 to L5) and stopped when the number is within a range of numbers. And According to the present invention, since the special symbol is drawn in the first game, it is possible to provide the game with the second game.

  In addition, in each of the display columns (R1, R2, R3), it is preferable that a certain special symbol and the next special symbol are arranged within the range of the predetermined number of moving symbols. According to this slot machine, a special symbol can be drawn on the winning line regardless of the timing of the player's operation, so there is no need to push the display line for some display columns, It becomes possible to concentrate on the column stop operation.

  In the slot machine described above, a symbol number is assigned to each symbol displayed in the display row (R1, R2, R3), and the stop control means (31) receives the stop operation signal (44a to 46a). ) At the timing of detecting the symbol number detecting means (31, 47 to 49) for detecting the symbol number of each display row (R1, R2, R3) at the reference position, the symbol number at the reference position and the stop operation A plurality of stop tables (TBL2) storing the number of moving symbols in association with the display sequence (R1, R2, R3) from the timing at which the signals (44a to 46a) are detected until they are stopped. Referring to the stop table (TBL2) selected from the plurality of stop tables (TBL2) according to the rules of the symbol number detecting means (31 47-49) reading the number of moving symbols corresponding to the symbol number detected, and moving the symbol by the number of moving symbols read from the timing at which the stop operation signal (44a-46a) is detected so as to stop. The display row (R1, R2, R3) is controlled, and the plurality of stop tables (TBL2) are arranged to display the special symbols within the predetermined number of moving symbols from the activated pay line (L1 to L5). A first stop table (TBL2) in which the number of moving symbols is stored so as to be drawn into the activated pay lines (L1 to L5), and the special symbols are activated in the first game and the second game. In the case of drawing into the converted pay lines (L1 to L5), it is preferable to select the first stop table (TBL2). Although the first game and the second game have different display row stop control methods, according to the present invention, the same stop table is used between games adopting different stop control methods. For this reason, the hardware configuration can be simplified. A plurality of stop tables are prepared in advance corresponding to the respective display columns, and it is a set of stop tables that stops the plurality of display columns.

  In the slot machine described above, each symbol displayed in the display row (R1, R2, R3) is assigned a symbol number, and the stop control means (31) receives the stop operation signal (44a). To 46a), the symbol number detecting means (31, 47 to 49) for detecting the symbol number of each display row (R1, R2, R3) at the reference position at the timing of detecting the symbol number, the symbol number at the reference position and the A plurality of stop tables (TBL2) that store the number of moving symbols in association with the display sequence (R1, R2, R3) from the timing at which the stop operation signal (44a to 46a) is detected until the display sequence (R1, R2, R3) is stopped. In the first game, the stop table (TBL2) selected from the plurality of stop tables (TBL2) according to a predetermined rule is referred to. The number of moving symbols corresponding to the symbol number detected by the symbol number detecting means (31, 47 to 49) is read out, and the number of moving symbols is read out from the timing when the stop operation signal (44a to 46a) is detected. It is preferable that the display row (R1, R2, R3) is controlled so as to be moved and stopped, and a predetermined stop table (TBL2) is always selected in the second game. The slot machine according to the present invention always selects a predetermined stop table in the second game. This is because, in the second game, a special symbol is drawn for some display columns, and it is not necessary to draw a specific symbol for other display columns because the display column is left to the player's skill. It is.

  In the slot machine described above, when the management information indicates the second game, the lottery means (31-33) determines whether the winning or losing is determined by a lottery, and indicates information indicating whether the winning is a losing or not. (ISD), and the predetermined condition is that the lottery information (ISD) indicates winning in the second game, and the stop control means (31) includes the lottery information (ISD) in the second game. ) Indicates winning, when the special symbol is within the predetermined number of moving symbols from the activated winning line (L1 to L5), the special winning line ( L1 to L5), while controlling a part of the display columns (R1, R2, R3) among the plurality of display columns (R1, R2, R3) to stop the lottery information (IS ) Indicates a loss, control at least one of the partial display columns (R1, R2, R3) so that the special symbol does not stop at the activated pay line (L1-L5). It is preferable.

  In this case, since the lottery for continuing the second game during the second game is executed, the diversity of the game is greatly improved. When the lottery result indicates a loss, kick control is performed for a part of the display columns so as not to stop on the winning line where the special symbol is activated. In the kick control, when the lottery result is a win, a plurality of display columns are stopped so that symbols corresponding to prizes other than the winning prize are not aligned on the activated winning line, and the lottery result is lost. This means that a plurality of display columns are stopped so that symbols corresponding to all prizes are not aligned on the activated winning line. In kick control, the type of the moving symbol is always identified, and when the symbol to be kicked is on the activated pay line, the program is controlled to advance the symbol by one. There is control. In the present invention, a stop table is used instead of the control control so as not to stop on a winning line where a predetermined symbol is validated. Therefore, it is not necessary to use a complicated program, and the processing load can be greatly reduced.

  In the slot machine described above, a symbol number is assigned to each symbol displayed in the display row (R1, R2, R3), and the stop control means (31) receives the stop operation signal (44a to 46a). ) At the timing of detecting the symbol number detecting means (31, 47 to 49) for detecting the symbol number of each display row (R1, R2, R3) at the reference position, the symbol number at the reference position and the stop operation A plurality of stop tables (TBL2) that store the number of moving symbols in association with the display sequence (R1, R2, R3) from the timing at which the signals (44a to 46a) are detected until they are stopped. A plurality of stop tables (TBL2) are arranged in front of the special symbols within the predetermined number of moving symbols from the activated pay lines (L1 to L5). A first stop table in which the number of moving symbols is stored with the predetermined number of moving symbols as a limit so as to be drawn into the activated winning lines (L1 to L5), and the special winning symbol is displayed on the activated winning line (L1). -L5) and a second stop table in which the number of moving symbols is stored so as not to stop. In the second game, when the lottery information (ISD) indicates winning, the first stop table (A B), when the lottery information (ISD) indicates a loss, the second stop table is selected, and the symbol number detecting means (31, 47-49) is referred to with reference to the selected stop table. The number of moving symbols corresponding to the symbol number detected by the above is read, and the symbol is moved by the number of moving symbols read from the timing when the stop operation signal (44a to 46a) is detected. It is preferable to control the part of the display columns (R1, R2, R3) so as to be stopped. In this case, since it is possible to control so that the stopped symbols of some display columns do not become special symbols, the lottery result can be reflected in the result of the second game.

The partial display columns (R1, R2, R3) are display columns (R1, R2, R3) corresponding to the stop operation immediately before the last stop operation from the first stop operation, and the other display columns ( R1, R2, R3) are display columns (R1, R2, R3) corresponding to the last stop operation, and the stop control means (31) is the plurality of stop operation means (7a, R3) in the second game. 7b, 7c) detects the stop operation order based on each stop operation signal (44a-46a), and controls the display columns (R1, R2, R3) and the other according to the detection result. It is preferable to switch the control for the display columns (R1, R2, R3). According to the present invention, since the special symbol can be drawn in the stop operation immediately before the last stop operation from the first stop operation, it is possible to make indefinite whether or not to win a prize until the last stop operation ends. . As a result, the fun of the second game is further improved.

  In addition, in the second game, the last stop operation is performed on the condition that the special symbol stops on the activated pay line (L1 to L5) in the stop operation immediately before the last stop operation from the first stop operation. There are at least two types of winning symbols to be awarded when stopped on the activated winning lines (L1 to L5) in FIG. 5, and payout means (31 ). In this case, since the payout is determined by the final stop operation regardless of the order in which the player operates the stop operation means, the game preference is further improved. Note that the number of symbols to be paid out in the last stop operation assigned to a certain display row is preferably varied according to the payout. In this case, since the player operates the stop operation means aiming at a high payout symbol, the fun of the game is further improved.

  In the second game, in the last stop operation, the special symbol stops on the activated pay line (L1 to L5) in the stop operation immediately before the last from the first stop operation. It is preferable that a winning is made even if any symbol stops on the validated winning line (L1 to L5). According to this invention, even a player with low skills can obtain some sort of payout.

  The slot machine according to the present invention includes a management means (31) for switching various games including a first game and a second game according to a predetermined condition and generating management information indicating a game type, and a plurality of special symbols. A plurality of display columns (R1, R2, R3) that cyclically variably display the types of symbols, and the variable display of the plurality of display columns (R1, R2, R3) is stopped, Among a plurality of winning lines (L1 to L5) crossing the display row (R1, R2, R3), a prize is given when the arrangement of the stopped symbols stopped on the activated winning lines (L1 to L5) is in a predetermined mode. And the prize includes one or more start prizes that are conditions for transition from the first game to another type of game, and a plurality of game types that do not change from the first game even if a prize is won. With a small prize The one or more start prizes include a second game start prize, which is a condition for winning a prize to shift to the second game, and the special symbols are aligned on the activated pay lines (L1 to L5). In the slot machine that wins the second game start prize, a stop operation signal (44a to 46a) is provided corresponding to each of the plurality of display columns (R1, R2, R3), and detecting a stop operation of the player. And a plurality of stop operation means (7a, 7b, 7c), and when the management information indicates a first game, one or a plurality of start prizes including a second game start prize, a plurality of small prizes If the management information indicates the second game, one or more prizes including the second game start prize and lose are decided by lottery. Then lottery If the lottery means (31-33) for generating lottery information (ISD) indicating the first game is displayed and the lottery information (ISD) indicates the second game start prize, the stop When the operation signal (44a to 46a) is detected, the special symbol is activated when the special symbol is within a predetermined number of moving symbols from the activated pay line (L1 to L5). The plurality of display rows (R1, R2, R3) are controlled so as to be drawn on the winning lines (L1 to L5) and stopped, the management information indicates the second game, and the lottery information (ISD) is the first When a two-game start prize is indicated, at the timing when the stop operation signal (44a to 46a) is detected, the special symbol is moved from the activated winning line (L1 to L5) to the predetermined movement map. A part of the plurality of display columns (R1, R2, R3) so as to draw and stop the special symbol on the activated pay line (L1 to L5) when the number is within the range of the number of patterns. The number of movement symbols less than the predetermined number of movement symbols from the activated winning line (L1 to L5) at the timing when the display row (R1, R2, R3) is controlled and the stop operation signal (44a to 46a) is detected. Other display columns (R1, R2, R3) among the plurality of display columns (R1, R2, R3) so as to stop the symbols separated by a number on the activated pay lines (L1-L5) And stop control means (31) for controlling.

  According to this invention, since the second game start prize is drawn during the second game, the second game can be continued even if the second game ends in one game. Furthermore, in order to win the second game start prize, it is necessary to stop a predetermined symbol on the activated pay line in another display row, so that a highly skilled player continues the second game. On the other hand, low-skilled players can lengthen the number of continuations of the second game.

  Here, the lottery means (31-33) compares the lottery probability of winning the second game start prize when the predetermined condition is satisfied in the first game as compared with the case where the predetermined condition is not satisfied. It is preferable to set a high value.

  Further, in the small role award, the special symbols stop on the activated pay lines (L1 to L5) in the partial display columns (R1, R2, R3), and the other display columns ( In R1, R2, and R3), it is preferable to include a prize that is awarded when a predetermined symbol other than the special symbol is stopped on the activated winning line (L1 to L5). In this case, even if it is determined that the second game start prize is not won due to a lack of special symbols, the combination of the special symbol and the small role symbol will result in winning, so that the preference of the second game is improves.

In addition, the special symbol is stopped on the activated pay lines (L1 to L5) in the partial display columns (R1, R2, R3), and the other display columns (R1 , R2, R3) includes a prize that is awarded when a predetermined symbol other than the special symbol is stopped on the activated winning line (L1 to L5), and the stop control means (31) When the management information indicates the second game and the lottery information (ISD) does not indicate the special prize, the special symbol is activated at the timing when the stop operation signal (44a to 46a) is detected. The partial display so that the special symbol is drawn onto the validated winning line (L1 to L5) and stopped when it is within the predetermined number of moving symbols from the winning line (L1 to L5). Row (R1 R2 and R3), and if the special symbol is present on the activated pay line (L1 to L5) at the timing when the stop operation signal (44a to 46a) is detected, the special symbol is the prize The other display columns (R1, R2, R3) are controlled so as not to stop on the lines (L1 to L5), and the activated winning lines (R1, R2, R3) L1 to L5) detects that the special symbol has stopped and the predetermined symbols have stopped on the activated pay lines (L1 to L5) in the other display columns (R1, R2, R3). And, it is characterized by having a winning determination means for determining a winning. According to the present invention, the kicking control of the special symbol is executed in the other display row, and as a result, the winning is achieved by the combination of the symbol that may stop on the activated winning line and the predetermined symbol combination. , The player will not give up winning in the middle of one game.

  In the slot machine described above, the plurality of types of symbols include specific symbols, and the small role prize includes the activated winning line (in the display columns (R1, R2, R3)). The specific symbols stop on L1 to L5), and predetermined symbols other than the special symbols stop on the activated pay lines (L1 to L5) in the other display columns (R1, R2, and R3) The stop control means (31) includes a prize that is awarded in the case where the management information indicates the second game, and the lottery information (ISD) does not indicate the second game start prize. At the timing when the stop operation signal (44a to 46a) is detected, when the specific symbol is within the predetermined number of moving symbols from the validated winning line (L1 to L5), the specific symbol is effective. The display columns (R1, R2, R3) are controlled so as to be drawn and stopped on the winning lines (L1 to L5), and at the timing when the stop operation signals (44a to 46a) are detected. If there is the special symbol on the activated winning line (L1 to L5), the other display columns (R1, R2, R3) so that the special symbol does not stop on the winning line (L1 to L5). And the specific symbols stop on the activated pay lines (L1 to L5) in the partial display columns (R1, R2, R3), and the other display columns (R1, R2, R3) ), A winning determination means for detecting that the predetermined symbol has stopped on the validated winning lines (L1 to L5) and determining the winning of the small role prize is provided.

  According to the present invention, when the second game start prize is not won during the second game, a specific symbol can be drawn on the winning line for some display columns, and for other display columns Controls kicking so that the special symbol does not stop. As for the other display columns, since a predetermined symbol other than the special symbol is stopped, a small role prize is won. Therefore, the second game is continued depending on the stop mode of the other display columns, or the small role award is received. It is decided whether to win a prize.

A liquid crystal display device 64 for presenting predetermined information to the player is provided on the upper stage of the front door 3. The panel display portion D in the middle stage of the front door 3 is provided with three vertically long display windows 4a, 4b, and 4c. The display windows 4a, 4b, and 4c are formed of a transparent material such as acrylic resin. Further, three winning lines L1 to L5 are provided horizontally and obliquely on the display windows 4a, 4b, and 4c.

  In addition, an auxiliary display unit 20 is provided on the left side of the display window 4a. The auxiliary display unit 20 is composed of five LEDs respectively corresponding to the pay lines L1 to L5. When the player inserts medals or performs a bet operation to be described later, the number of pay lines L1 to L5 corresponding to the number of bets becomes valid. In this slot machine 1, the winning line L1 is valid when the number of bets is one, the winning lines L1 to L3 are valid when the number of bets is two, and the winning lines L1 to L1 when the number of bets is three. L5 becomes effective. Each LED constituting the auxiliary display unit 20 is turned on when the corresponding winning line L1 to L5 is valid, and is turned off when the corresponding winning line L1 to L5 is invalid. Thus, the player can know which winning lines L1 to L5 are valid.

  Inside the panel display D, three rows of left, middle and right reels R1, R2 and R3 each having a plurality of types of symbols drawn on the outer peripheral surface thereof are rotatably provided. FIG. 2 shows the structure of the left, middle, and right reels R1, R2, and R3, and FIG. 3 shows the detailed structure of the right reel R3. Each of the reels R1 to R3 has an annular shape, and various symbols are printed on its surface (surface visible from the display windows 4a to 4c). A light shielding film S that shields light is formed on the back surface of the right reel R3 except for a part thereof. In the portion where the light shielding film S is formed, light is not transmitted even if light is irradiated from the back side. On the other hand, the light shielding film S is not formed on each design portion, and the uneven member P for scattering light is formed on the back surface of the right reel R3. In addition, the reel of each design part is white and translucent. In the example shown in FIG. 3, the concavo-convex member P is formed inside the contour portion of the symbol “7”.

When one medal is inserted, the winning line L1 is activated, when two medals are inserted, the winning lines L1 to L3 are activated, and when three medals are inserted, the winning lines L1 to L5 are activated. Further, when the player inserts more than 3 medals, the slot machine 1 stores the number of medals of 4 or more as credits. The slot machine 1 includes a storage device therein. The storage device stores the medals acquired by the medals inserted into the slot machine 1, so that the player can operate the buttons and other devices without newly inserting medals into the slot machine. It is a device that can provide a predetermined number of medals from among medals in order for a game, and is used for the game based on the total number of medals entered in the slot machine and medals acquired by the game. It is possible to record the number obtained by subtracting the total number of objects by an electromagnetic method.

  The BET button 15 is provided on the lower left side of the display window 4a. The BET button 15 is used for designating the number of medals bet by the player in one game. By operating the BET button 15 by the player, the stored medals can be bet without inserting medals from the medal insertion slot 5. Therefore, the winning lines L1 to L5 are appropriately enabled according to the number of medals designated by operating the BET button 15. The relationship between the number of medals designated by the operation of the BET button 15 and the valid pay lines L1 to L5 is the same as when medals are directly inserted.

  The start lever 6 is provided below the BET button 15. The start lever 6 is used by the player to instruct the start of the game. When the player depresses the start lever 6, the reels R1, R2, and R3 start to rotate all at once, and the symbols in the display windows 4a, 4b, and 4c are variably displayed.

  On the right side of the reel stop button 7c, a credit check button 8 is provided for returning medals stored as credits to the medal tray 10.

<2: Role>
FIG. 4 shows an example of symbols displayed on the left / middle / right reels R1, R2, and R3. As shown in the figure, 21 symbols and 7 types of symbols are displayed on each reel R1, R2, R3, and symbol numbers PN = 1 to 21 are assigned to the symbols.

  In a game by the slot machine 1, when a predetermined combination of symbols is aligned on the winning lines L1 to L5 enabled by inserting medals, the number of medals corresponding to the aligned symbols is paid out. The medal is inserted into the slot machine 1 when starting the game, and is necessary for the player to continue the game. That is, a medal can be said to be a medium (game medium) having a game value such as continuation of a game. In this case, the medal corresponds to the game value. Note that an information recording medium such as a magnetic card or an IC card in which information corresponding to the number of medals is recorded is also included in the game medium.

  Of the arrangement (combination) of symbols, the one that gives game value is called “role”, and is distinguished from “valueless” non-winning. The game value refers to a privilege given to the player, and includes transferring a predetermined amount of medals to the player and shifting from one type of game to another type of game. The type of game value given as a result of one game is called “prize”, and obtaining “prize” is called “winning”. The awards are broadly classified into a start prize that shifts from a normal game to another type of game and a small role award (payout prize) in which medals are paid out. The start prize may be accompanied by a medal payout, or may not be paid out.

  The types of games that can be executed by the slot machine 1 include normal games, regular bonus games (hereinafter referred to as RB games), big bonus games (hereinafter referred to as BB games), and challenge bonus games (hereinafter referred to as CB games). ), A free bonus game (hereinafter referred to as FB game), and a replay game. The RB game start prize is called RB prize, the BB game start prize is called BB prize, the CB game start prize is called CB prize, the FB game start prize is called FB prize, and the replay game start prize is called replay prize. In the RB award, BB award, CB award, and FB award, 15 medals are paid out by winning, but even if a replay prize is won, no medal is paid out.

  The CB game is a game in which the winning probability of the FB prize in the internal lottery is different from that of the normal game, and the winning probability of the FB prize of the present embodiment is higher in the CB game than in the normal game. However, there is a limit to the number of medals acquired during the CB game, and the CB game is terminated before the predetermined number is exceeded. In the FB game, stop control is executed for at least one reel regardless of the result of the internal lottery, and the operation ends in one game. Therefore, in the FB game, kick control is not executed for at least one reel. In the following description, the FB game in the CB game is referred to as the FB in CB, and the FB game won in the normal game is referred to as the single FB.

  A replay game refers to a game that can be played without inserting medals (including providing medals for games by operating buttons and other devices related to the storage device). The RB game ends when the JAC game is played 12 times or a maximum of 8 times is won. The JAC game is played by betting one medal and enabling only the central pay line L1. JAC games will adopt the JAC Award. When winning the JAC Award, the slot machine 1 pays out 15 medals.

  The BB game has a higher probability of winning the RB prize than the normal game. However, there is a limit to the number of medals that the player can acquire during the BB game, and the BB game is terminated before the predetermined number is exceeded. In the following description, in order to distinguish between RBs in the BB and RBs that have won alone, the former is referred to as RB in BB and the latter is referred to as single RB.

  On the other hand, the small role prize includes a cherry prize with two medal payouts, a bell prize with five medal payouts, and a watermelon prize with seven medal payouts. The relationship between roles and prizes is as follows.

  1) Red 7 Role This role is a sequence of symbols with symbol numbers PN = 1 and 7 on the left reel R1, symbols with symbol number PN = 9 on the middle reel R2, and symbols with symbol numbers PN = 1 and 9 on the right reel R3. It is. The red 7 role corresponds to the BB prize and is an opportunity to shift from the base game to the BB game.

<3: Electrical configuration of slot machine>
FIG. 5 is a block diagram showing a control device that controls the game processing operation in the slot machine 1 and a circuit configuration including peripheral devices related to the present invention among those constituting the slot machine 1.

  The control device includes main board 30A and sub board 30B as main components. The main board 30A includes a CPU 31, a clock generation circuit 32, a sequence generation circuit 33, a RAM 34, a ROM 35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38 and an output port 39.

  The CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 executes the first control program CP1 and controls each component. The first control program CP1 describes how to operate the entire slot machine 1. For this reason, the CPU 31 functions as a control center of the slot machine 1. The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a reference clock signal CLK having a fixed period, and supplies the reference clock signal CLK to the CPU 31 and the number sequence generation circuit 33.

  The sequence generator 33 is composed of a high-speed ring counter, and counts the reference clock signal CLK to generate count data CD. The numerical value range of the count data CD is, for example, 0 to 65535, depending on the contents stored in the prize group lottery table TBL1 described later. The count data CD can be input to the CPU 31 through the input port. The CPU 31 detects the timing when the player depresses the start lever 6 and reads the count data CD through the input port at the timing. Sampling data SD is generated.

  Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pushed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value sampled from a random number. Since the sequence generator 33 operates in synchronization with the reference clock signal CLK, the cycle of the count data CD is extremely short. For example, if the frequency of the reference clock signal CLK is 30 MHz, the time required for the value of the count data CD to change from “0” to “65535” is 2.2 msec. Therefore, even if the player can know the value of the count data CD by unauthorized means, it is impossible to cause the CPU 31 to generate sampling data SD having a desired value by operating the start lever 6.

  Next, the RAM 34 functions as a work area of the CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like. For example, internal lottery data ISD indicating the result of the internal lottery is stored in the RAM 34.

  In addition to the first control program CP1, the ROM 35 stores a prize group lottery table group TBL1, a stop table group TBL2, a winning symbol combination table TBL3, and the like. In the winning symbol combination table TBL3, combinations of winning symbol combinations and medal payout numbers for winning combinations are stored in association with each other.

  Since the control of the slot machine 1 requires control according to the difference in game value, it is convenient to classify various roles by paying attention to the game value. In the slot machine 1 of the present embodiment, one prize group is assigned to each combination, but one or more combinations may be assigned to one prize group.

  Next, the prize group lottery table group TBL1 includes a plurality of prize group lottery tables. CPU31 performs internal lottery using the prize group lottery table selected according to the gaming state. As a prize group lottery table, a table used for a normal game, a table used for a BB game, a table used for an RB game, a table used for a CB game, and a table used for an FB game are prepared.

  FIG. 6 shows the stored contents of the prize group lottery table TBL11 for the base game. As shown in this figure, the prize group lottery table TBL11 stores lottery division data in the first to ninth storage areas ADR1 to ADR9, respectively. The value of the lottery category data indicates the width of the lottery category corresponding to each prize group. For example, the lottery classification data stored in the first storage area ADR1 corresponds to the loss, and the value is “59536”. The lottery classification data stored in the ninth storage area ADR9 corresponds to the BB prize, and its value is “200”.

  FIG. 7 is a flowchart showing the operation of the CPU 31 in the internal lottery process using the prize group lottery table TBL11. First, the CPU 31 performs an initialization process (step S1). Specifically, the value of the variable N is reset to “0” and the value stored in the internal register is reset to “0”.

  Next, the CPU 31 stores the sampling data SD in the internal register (step S2), and subsequently changes the value of the variable N to N + 1 (step S3). Thereafter, the CPU 31 reads the lottery classification data from the Nth storage area (step S4). In the process immediately after the initialization process, since the value of the variable N is “1”, the lottery classification data is read from the first storage area ADR1. The value in this case is “59536”.

  Next, the CPU 31 reads the stored contents of the internal register, adds the read data value and the lottery classification data value, and stores the added value in the internal register (step S5). As a result, the content stored in the internal register is updated from the original data value to the added value.

  Next, the CPU 31 determines whether or not the added value is greater than or equal to the reference value (step S6). The reference value is equal to the sum of the values of the lottery classification data stored in the first to ninth storage areas ADR1 to ADR9.

  If the added value is less than the reference value, the CPU 31 returns the process to step S3, and repeats the processes from step S3 to step S6 until the added value becomes equal to or greater than the reference value. When the added value is equal to or greater than the reference value, the CPU 31 advances the process to step S7, determines a prize group according to the value of the variable N, and generates internal lottery data ISD. Specifically, when N = 1, it is a loss, when N = 2, a replay prize, when N = 3, a cherry prize, when N = 4, a bell prize, when N = 5, a single FB prize, when N = 6, a watermelon It is determined that the CB prize is won when N = 7, the RB prize when N = 8, and the BB prize when N = 9. As a result, as shown in FIG. 6, the correspondence between the sampling data SD and the prize group is lost at SD = 65535-6000, replay prize at SD = 5999-4300, cherry prize at SD = 4299-3300, SD = 3299 to 2400 for the Bell Award, SD = 2399 to 1600 for the Single FB Award, SD = 1599 to 900 for the Watermelon Award, SD = 899 to 500 for the CB Award, SD = 499 to 200 for the RB Award SD = 199 to 0 corresponding to the BB prize.

  Then, the CPU 31 generates internal lottery data ISD based on the determination result. The internal lottery data ISD includes the BB award for the first bit, the RB award for the second bit, the CB award for the third bit, the Bell award for the fourth bit, the watermelon award for the fifth bit, the cherry award for the sixth bit, A replay award is assigned to 7 bits and a single FB award is assigned to the 8th bit. If any prize is won by internal lottery, the CPU 31 sets the value of the corresponding bit to “1”, otherwise sets the value of the bit to “0”. Therefore, by referring to the internal lottery data ISD, it is possible to know whether the player has won or lost, and the winning group that has won.

  In the following description, the first bit of the internal lottery data ISD is called a BB winning flag, the second bit is called an RB winning flag, and the third bit is called a CB winning flag. Then, setting each flag to “1” is referred to as setting, and setting to “0” is referred to as clear. With regard to a small role, even if a game is won by an internal lottery, no medal will be paid out unless the game is won. However, for the RB prize, the BB prize, and the CB prize, when winning in an internal lottery of a certain game, the BB winning flag, the RB winning flag, and the CB winning flag are not cleared without winning in the game. The BB winning flag, the RB winning flag, and the CB winning flag are maintained until winning in the game. This is called carrying over the winning flag. As described above, the internal lottery is executed for each game, and the internal lottery data ISD is generated. The lottery result is valid only in the game except for winning the RB prize, the BB prize, and the CB prize. Thus, even if the winning flag is carried over, the internal lottery is executed for each game. For example, when the watermelon prize is won in the internal lottery in the game in which the winning flag of the BB prize is carried over, the internal lottery data ISD In this state, the values of the first bit and the fifth bit are set to “1”. Further, if neither game is won in this game, only the fifth bit is cleared to “0” and the first bit remains set to “1”.

  Next, the stop table group TBL2 is composed of a plurality of stop tables. In each stop table, a symbol number PN (symbol number at the reference position) displayed on the central pay line L1 and advancing frame number data indicating the advancing frame number (moving symbol number) are stored in association with each other. . Here, the number of advance frames is a symbol that advances from when the player depresses each of the left / middle / right reel stop buttons 7a, 7b, 7c until the left / middle / right reels R1, R2, R3 stop. A number.

  Since each of the left, middle, and right reels R1, R2, and R3 rotates at high speed, even if the player operates the stop button aiming at a specific symbol, skill is required to stop the desired symbol. There are individual differences in the mastery of the stop button operation. In particular, it is difficult for a player with low moving eyesight to stop a desired symbol. On the other hand, a highly skilled player can operate the stop button when a desired symbol is displayed on the winning line.

  However, in order for a low-skilled player to enjoy the game, it is necessary to make it easy to align the symbols to some extent. On the other hand, when the result of the internal lottery is lost, it is necessary to control the rotation of the reel so that the combination is not established There is. The stop table is used to control such reel rotation. The stop positions of the left, middle, and right reels R1, R2, and R3 are determined with reference to the stop table.

  Returning to FIG. 5, the description will be continued. The transmission timing control circuit 36 and the data transmission circuit 37 shown in the figure transmit to the sub-board 30B information on the type of combination determined by the internal lottery and the stop table selected corresponding to the combination. The sub-board 30B is responsible for processing for notifying the player of predetermined information.

  Next, the input port 38 is an input interface for signals supplied from various sensors described later. On the other hand, the output port 39 is an output interface for supplying control signals to each motor and various devices.

  The main input signal generating means connected to the input port 38 and generating various input signals includes the following. The inserted medal detection sensor 41 detects a medal inserted through the medal slot 5 and generates one output pulse for one medal. Therefore, the CPU 31 can detect the number of inserted medals by counting the output pulses.

  The BET button sensor 42 detects the operation of the BET button 15. The start lever sensor 43 detects the operation of the start lever 6 and outputs a start operation signal 43a. The left / middle / right reel stop button sensors 44, 45, 46 detect the operations of the left / middle / right reel stop buttons 7a, 7b, 7c, respectively, and output stop operation signals 44a, 45a, 46a, respectively. The left / middle / right reel position detection sensors 47, 48, 49 detect the rotational positions of the left / middle / right reels R1, R2, R3, and generate detection signals 47a, 48b, 49c. The CPU 31 detects these signals and acquires the operation timing of the start lever 6, the operation timings of the reel stop buttons 7a, 7b, and 7c, and the rotation positions of the reels R1, R2, and R3.

  The right reel position detection sensor 49 includes a photocoupler 492, an amplifier, and a comparator shown in FIGS. The photocoupler 492 includes a light emitting unit and a light receiving unit. When the light receiving unit outputs a light reception signal at a level corresponding to the amount of light received, the amplifier amplifies the light reception signal. The comparator compares the output signal of the amplifier with a predetermined threshold value to generate a detection signal 49a, and outputs this as an output signal of the right reel position detection sensor 49. When the right reel R3 rotates, the light shielding piece 491 shown in FIG. 2 passes through the photocoupler 492 once per rotation. Therefore, the rotation position of the right reel R3 can be detected by the detection signal 49a. The left / middle position detection sensors 47 and 48 are configured in the same manner as the right reel position detection sensor 49.

  As main means connected to the output port 39 and supplied with various output signals, there are left, middle and right reel drive motors 51, 52 and 53. The left, middle, and right reel drive motors 51, 52, and 53 are motors that respectively rotate the left, middle, and right reels R1, R2, and R3, and in this example, are constituted by stepping motors. Therefore, the CPU 31 stops the left, middle, and right reels R1, R2, and R3 by adjusting the number of pulses of the drive signals 51, 52a, and 53a supplied to the left, middle, and right reel drive motors 51, 52, and 53. It is possible to determine the position accurately.

  Each of the motors 51, 52, and 53 is configured to rotate once by 400 pulses. As described above, 21 symbols are formed on each of the reels R1, R2, and R3. Of these, 20 symbols advance by 1 pulse with 19 pulses, and 1 symbol advances by 1 pulse with 20 pulses. Further, the CPU 31 counts the number of pulses supplied to the motors 51, 52, and 53, and holds the count result as position data MD1, MD2, and MD3. The values of the position data MD1, MD2, and MD3 are reset when the detection signals 47a, 48a, and 49a become active.

  FIG. 8 is a timing chart showing the relationship between the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3. As shown in this figure, when the detection signal 49a rises from the low level to the high level at time t1, the value of the position data MD3 is reset. Time t1 is timing when the light shielding piece 491 shown in FIG. 3 passes through the photocoupler 492. At this time, as the rotational position of the right reel R3, the symbol (BAR) of the symbol number PN = 1 shown in FIG. 4 is displayed in the middle of the display window 4c. In other words, the mounting position of the light shielding piece 491 and the photocoupler 492 is determined so that the symbol is displayed in the middle of the display window 4c.

  When 20 pulses are supplied to the right reel drive motor 53 as the drive signal 53a in the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel R3 by 1/21. As a result, the symbol (cherry) of symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4c. Thereafter, the symbols are sequentially displayed in the same manner, and when the time t3 is reached, the right reel R3 makes one rotation and the symbol (BAR) of the symbol number PN = 1 is displayed again. Thus, since the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3 are closely related, the CPU 31 can detect the display state of the symbol based on the position data MD3.

  As for the left reel R1 and the middle reel R2, as with the right reel R3 described above, the CPU 31 can detect the display state of the symbols based on the position data MD1 and MD2.

  Next, the sub board 30B includes a CPU, a data input circuit, a clock generation circuit, a ROM, a RAM, and a liquid crystal display control circuit 60, and causes the liquid crystal display device 64 to display various effects. The sub-board 30 </ b> B controls turning on / off the left / middle / right backlights 65 to 67 and emits sound effects from the speaker 68.

  The CPU of the sub board 30B receives various commands transmitted from the main board 30A. This command includes internal lottery data ISD and the like. Based on the BB winning flag and CB winning flag of the internal lottery data, the CPU displays an animation and a character on the liquid crystal display device 64 in order to notify the player that the BB prize or CB prize has been won. In addition, a predetermined sound is emitted from the speaker 68 when the start lever 6 is operated.

<4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. 9 and 10 are flowcharts showing the operation of the CPU 31 controlling the slot machine 1 from the start to the end of one game. One game period is a period from when a bet operation is accepted until the next bet operation is accepted.

  The CPU 31 determines whether or not the player has made a bet operation based on detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to S12.

  In step S <b> 12, the CPU 31 determines whether the player has operated the start lever 6 based on the detection signal of the start lever sensor 43. When the player operates the start lever 6, the CPU 31 performs a process for prohibiting a bet operation (step S13). If the bet operation is prohibited, even if the player inserts a medal or operates the BET button 15 during the period until the prohibition is canceled, the acceptance is rejected.

  Next, the CPU 31 sets a prize group lottery table according to the game mode according to the first control program CP1 (step S14). Specifically, a table corresponding to a gaming state (game type) such as a base game, an RB game, a BB game, a CB game, and an FB game is selected from the prize group lottery table group TBL1. In this case, the CPU 31 refers to the RB game flag, the BB game flag, the CB game flag, and the like stored in the RAM 34, identifies the game type of the game, and selects a table based on the result. Note that the flag indicating the type of game is set in steps S170, S173, S187, S198, etc., which will be described later.

  In the internal lottery of the FB game, there are the following two modes. In the first aspect, winning or losing is determined by lottery. However, it is preferable to make the lottery probabilities different between the FB in CB and the single FB (FB game in the normal game). The second mode does not execute internal lottery.

  Next, the CPU 31 executes an internal lottery process using the prize group lottery table TBL1 set in step S14 (step S15). That is, the type of prize group lottery table TBL1 also changes according to the type of game. Thereafter, the CPU 31 determines whether the base game, the BB game, the CB game, the RB game, and the FB game are in progress based on a flag (management information) indicating the type of game (step S16). If it is determined that the game is a normal game, a BB game, or a CB game, the CPU 31 advances the process to step S17, and executes a winning flag setting process. The contents of the winning flag setting process are shown. Specifically, as described with reference to FIG. 7, first, the CPU 31 samples the count data CD and obtains the sampling data SD at the timing when the detection signal of the start lever sensor 43 becomes active. To do. Second, the CPU 31 refers to the prize group lottery table and sets a winning flag. The BB game or CB game is different from the normal game in the winning probability of the RB prize or the FB prize, but the type of prize adopted is the same as that of the normal game. Accordingly, the winning flag setting process is the same for the base game, the BB game, and the CB game.

  FIG. 11 shows the contents of the winning flag setting process in the base game, the BB game, or the CB game. The CPU 31 determines whether or not the BB is won (step S50). If it is won, the BB winning flag is set (step S51). If the BB prize is not won, the process proceeds to step S52. Next, the CPU 31 determines whether or not the CB is won (step S52). If the CB is won, the CPU 31 sets a CB winning flag (step S53). If the CB prize is not won, the process proceeds to step S54. Next, the CPU 31 determines whether or not it is a single RB win (step S54), and if it is a win, sets a single RB win flag (step S55). Proceed to Next, the CPU 31 determines whether or not the BB winning RB has been won (step S56). If the winning has been won, the CPU 31 sets the BB winning RB winning flag (step S57). Proceed to step S58. Next, the CPU 31 determines whether or not it is a single FB win (step S58). If it is a win, the single FB win flag is set (step S59). Proceed to Next, the CPU 31 determines whether or not the CB FB win is selected (step S60). If the CB is selected, the CPU 31 sets the CB FB winning flag (step S61). Proceed to step S62. Next, the CPU 31 determines whether or not the bell is won (step S62). If the bell is won, a bell winning flag is set (step S63). If the bell is not won, the process proceeds to step S64. Next, the CPU 31 determines whether or not the watermelon is won (step S64). If the watermelon is won, the CPU 31 sets a watermelon winning flag (step S65). If the watermelon prize is not won, the process proceeds to step S65. Next, the CPU 31 determines whether or not the cherry is won (step S66). If the cherry is won, the CPU 31 sets a cherry winning flag (step S67). If the cherry award is not won, the process proceeds to step S68. Next, the CPU 31 determines whether or not the replay is won (step S68), and if it is won, the replay winning flag is set (step S69).

Next, when it is determined in step S16 shown in FIG. 9 that the RB game is in progress, the CPU 31 advances the process to step S18 and executes a winning flag setting process. Specifically, as shown in FIG. 12, the CPU 31 determines whether or not the JAC is won. If the JAC prize is won, the CPU 31 sets the JAC winning flag while the JAC prize is not won. Finishes the process without setting the JAC winning flag.

  Next, when it is determined in step S16 shown in FIG. 9 that the FB game is in progress, the CPU 31 advances the process to step S19 and executes a winning flag setting process. When the internal lottery is the first mode described above, the CPU 31 determines whether or not the winning is made as shown in FIG. 13 (step S81). S82) On the other hand, in the case of a loss, the process is terminated without setting the FB small combination flag. That is, in the internal lottery, it is different from the normal game or the CB game in which only the winning or the lost game is drawn by lottery.

  On the other hand, when the internal lottery is the second mode described above, the internal lottery itself is not executed. In this case, the winning flag may be set during the FB game. Specifically, step S15 shown in FIG. 9 is omitted, and the FB small combination flag is set in step S19 as shown in FIG. 14 (step S83). Thereby, in the FB game, the FB small combination flag is set without executing the lottery.

  Further, an FB prize lottery may be executed during the FB game. In this case, it is determined whether or not the FB prize is won in the first aspect of the internal lottery, and it is first determined in step S18 whether or not the FB prize is won (step S84). ). When the FB prize is won, the CPU 31 sets the FB winning flag during FB (step S85), whereas when the FB prize is not won, the CPU 31 sets the FB small part flag (step S86).

  Next, in step S20 shown in FIG. 9, a reel stop data group selection process is executed based on the winning flag of the base game, BB game, or CB game set in step S17. FIG. 16 shows the processing contents of reel stop data group selection in the base game, BB game, or CB game. The CPU 31 refers to the winning flag of the internal lottery data ISD, and replays a winning flag, a watermelon winning flag, a bell winning flag, a cherry winning flag, a BB winning flag, a CB winning flag, a single RB winning flag, and an RB winning RB winning flag. Are sequentially determined (step S90 to step S97). If the replay winning flag is set, the CPU 31 selects the replay stop data group (step S98). If the watermelon winning flag is selected, the CPU 31 selects the watermelon stop data group (step S99). If the winning flag is set, the stop data group for bell is selected (step S100). If the cherry winning flag is set, the stop data group for cherry is selected (step S101), and the BB winning flag is set. If so, the BB stop data group is selected (step S102). If the CB winning flag is set, the CB stop data group is selected (step S103). If the single RB winning flag is set, the RB winning data group is selected. A stop data group is selected (step S104). If the RB winning flag in BB is set, R in BB Selecting use stop data group (step S105).

  Next, in step S21 shown in FIG. 9, a reel stop data group selection process is executed based on the winning flag of the RB game set in step S18. FIG. 17 shows the processing contents of the reel stop data group selection in the RB game. The CPU 31 refers to the winning flag of the internal lottery data ISD and determines whether or not the JAC winning flag is set (step S110). If the JAC winning flag is set, the CPU 31 selects the JAC stop data group (step S111). If the JAC winning flag is not set, the CPU 31 selects the non-winning stop data (step S112). Here, the stop data group for JAC is set so that the plum symbol can be drawn into the central winning line L1 as shown in FIG. More specifically, at the timing when the CPU 31 detects the stop operation signals 44a to 46a, if the plum symbol is within a predetermined number of moving symbols from the winning line L1, the plum symbol is drawn onto the winning line L1. The reels R1 to R3 are controlled so as to be stopped. In the JAC game, only one bet is allowed, so the pay line L1 is an activated pay line. In this example, the number of moving symbols is set to “4”. Accordingly, a plum symbol in the range of 0 frame to 4 frames is drawn into the winning line L1.

  Next, in step S22 shown in FIG. 9, a reel stop data group selection process is executed based on the winning flag of the FB game set in step S19. FIG. 19 shows the processing contents of reel stop data group selection in the FB game. The CPU 31 refers to the winning flag of the internal lottery data ISD and determines whether or not the winning flag for the FB prize is set (step S115). Then, the CPU 31 selects the FB stop data group if the FB winning flag is set (step S116), and selects the small role stop data if the FB winning flag is not set (step S117). Here, the FB stop data group is set so that the plum symbol can be drawn into the activated pay line as shown in FIG. More specifically, at the timing when the CPU 31 detects the stop operation signals 44a to 46a, the plum symbol is activated when the plum symbol is within a predetermined number of moving symbols from the activated winning line. The reels R1 to R3 are controlled so as to be drawn on the winning line and stopped. Further, the small combination stop data group selected in step S117 is set so as not to stop the plum symbol on the activated pay line in the third stop.

  The FB game may be a single bet game or a multiple bet game. In the former case, it is preferable that the FB stop data group selected in step S116 is also used as the JAC stop data group in the RB game. On the other hand, in the latter case, it is preferable that the FB stop data group selected in step S116 is also used as the replay stop data group in the normal game. In these cases, the predetermined number of moving symbols is set to “4”. Thus, by sharing the stop data group between different types of games, the number of stop tables can be reduced and the data capacity of the ROM 35 can be reduced.

  As for the arrangement of the plum symbols constituting the plum role of the FB prize, as shown in FIG. 4, the distance between the most separated plum symbols is 5 symbols. Therefore, by setting the predetermined number of moving symbols to “4” as described above, the plum symbol is always placed on the activated pay line regardless of the timing at which the player operates the reel stop buttons 7a to 7c. Can be pulled in. In this example, the plum symbol is adopted for the FB prize, but a plurality of types of symbols may be adopted. In this case, it is preferable that the symbol arrangement on the reel is set so that a predetermined number of moving symbols such as a bell symbol can be drawn on the winning line.

  Returning to FIG. When the selection of the above-described reel stop data group is completed, the CPU 31 sets each reel driving flab indicating that the reel is rotating, starts reel rotation (step S23), and executes reel rotation stop processing. (Step S24 shown in FIG. 10). The reel rotation stop process will be described later.

  Next, the CPU 31 determines whether or not a replay prize has been won by comparing with a plum combination that is a combination of a symbol on the activated line of each reel and a symbol of the replay prize (step S25). When winning the replay prize, the same winning line as the winning line activated in the previous game is automatically activated without performing a betting operation. For this reason, when winning the replay prize, the CPU 31 clears the replay winning flag (step S26), and then returns the process to step S12.

  Next, the CPU 31 determines whether the game type is a normal game, a BB game, a CB game, an RB game, or an FB game (step S27). Then, the CPU 31 advances the process to step S28 if it is a base game, BB game or CB game, advances the process to step S29 if it is an RB game, advances the process to step S30 if it is an FB game, and determines a winning determination process. Execute. Thereafter, the CPU 31 executes a one-game end process (step S31) and cancels the prohibition of the betting operation (step S32).

  FIG. 21 is a flowchart showing the processing contents of the reel rotation stop processing (step S24). First, the CPU 31 determines whether or not the first button stop operation has been performed based on the stop operation signals 44a to 46a (step S120).

  When the first stop operation of the reel stop button is detected, the CPU 31 acquires the stop button number (button type) of the currently pressed reel stop buttons 7a to 7c (step S121), and the pattern immediately after the stop operation is obtained. The number PN is acquired (step S122). Specifically, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, and 7c are pressed based on the stop operation signals 44a to 46a from the reel stop button sensors 44 to 46, and the symbol number PN at the timing. To get. In this example, the stop button number “1” is assigned to the reel stop button 7a, the stop button number “2” is assigned to the reel stop button 7b, and the stop button number “3” is assigned to the reel stop button 7c.

  Next, the CPU 31 limits the usable stop data table group based on the internal lottery data ISD, the stop button number, the symbol number PN, etc. from the stop data table group selected in steps S20 to S22 ( In step S124), a combination of stop data tables for each stop operation order is specified. When there are a plurality of combinations, the CPU 31 specifies a combination of stop tables to be used by lottery or the like. When there are not a plurality of combinations, the combinations are specified. As a result, the CPU 31 determines one stop data table to be used for the first stop of the reel. (Step S125)

  Next, the CPU 31 acquires the advance frame number (moving symbol number) corresponding to the symbol number from the determined stop table (step S126), and then stops the reel that has been stopped based on the advance frame number. (Step S127).

  Next, the CPU 31 determines whether or not the second button stop operation has been performed based on the stop operation signals 44a to 46a (step 128). If there is a second button stop operation, the stop button number is acquired ( In step S129), the symbol number is acquired (step S130), the stop table corresponding to the second stop of the reel is determined from the combination of the stop tables specified in step S124 (step S131), and the advance frame number is acquired (step S132). ) And reel stop (step S133). Thereafter, the CPU 31 determines whether or not the third button stop operation has been performed based on the stop operation signals 44a to 46a (step S134). If there is a third button stop operation, acquisition of the stop button number ( In step S135), the symbol number is acquired (step S136), the stop table corresponding to the third stop of the reel is determined from the combination of the stop tables specified in step S124 (step S137), and the advance frame number is acquired (step S138). ) And reel stop (step S139). As described above, the CPU 31 selects a stop table to be used for stop control from among a plurality of stop tables according to the type of game, the result of the internal lottery, and the order of the stop operation of the reel stop button.

  FIG. 22 shows a set of stop tables for stopping the plum symbol on the central pay line L1. For example, if the acquired symbol number PN is “18” on the left reel, the corresponding advance frame number is “1”, so that the plum symbol stops on the winning line L1 by one frame deviation from the cherry symbol. It will be. In the FB game, in the first stop and the second stop, the stop table to which the plum symbol is drawn is selected. In the third stop, the CPU 31 is closest to the winning line activated at the timing when the stop operation signal is detected. Stop. Here, if the player operates the right reel stop button 7c in the last stop operation, the CPU 31 stops the right reel R3 with reference to, for example, the stop table A shown in FIG.

  In this case, since the number of advance frames stored in the stop table A is all “0”, the symbol closest to the activated pay line is stopped on the pay line. As described above, in the FB game, the FB bell role, the FB watermelon role, and the FB cherry role are adopted as the small role awards. When the reel stop button 7c is pushed down at the timing of the thick frame in FIG. Win a prize. As shown in FIG. 24, the payouts of the bell prize, watermelon prize, and cherry prize in the FB game may be different. In this case, since the player operates the reel stop button aiming at a symbol having a large payout, it becomes possible to give a payout according to the skill of the player. Note that the payout may be set to increase as the number of symbols assigned to the right reel R3 decreases. In this case, the skill of the player can be further reflected in the number of payouts obtained in the FB game.

  Further, in the FB game, when the CPU 31 executes the FB prize lottery, the stop table A may be used or the stop table B may be used. When the stop table A is used, the maximum pull-in number for the third stop is “0”, and so-called stop control of bitter stop is performed. On the other hand, in the stop table B, when the reel stop button 7c is operated, when the symbol numbers PN are “18”, “14” “9”, “5”, and “1”, the right reel R1 has one frame. The number of advance frames is stored so that the plum symbol is advanced and stopped on the activated pay line L1. Therefore, for the shaded portion, the plum symbol can be stopped and the maximum number of pull-in is “1”. Since the maximum number of pull-ins for the first stop and the second stop is “4”, the maximum number of pull-ins for the third stop is set smaller than that for the first stop and the second stop. That is, in the FB game, at the timing when the CPU 31 detects the stop operation signal, the CPU 31 validates the plum symbol when the plum symbol is within a predetermined number of moving symbols (four frames) from the activated pay line. The reels related to the first stop and the second stop are controlled so as to be drawn and stopped on the converted pay line, and the predetermined number of moving symbols (4 frames) from the pay line activated at the timing when the stop operation signal is detected. ) The reel related to the third stop is controlled so that the symbols separated by a smaller number of moving symbols (one frame or zero frame) are stopped on the activated pay line.

  In the case where the internal lottery of the FB game is the first mode described above, a lottery for determining whether or not to win the FB prize is executed. However, small prizes such as a bell prize, watermelon prize, and cherry prize are awarded. There is no other lottery. In this case, if the FB prize is won by lottery, it is allowed to stop the plum symbol on the activated winning line in the first stop and the second stop, but if the FB prize is unfair, the first The reel is controlled so as not to stop on the winning line in which the plum symbol is validated by stop control of at least one of the stop and the second stop (kick-off control). For example, when the reel related to the first stop is the left reel R1, the CPU 31 selects a stop table for kicking the plum symbol from the activated pay line (L1 in this example) as shown in FIG. In the third stop, it is allowed to stop the plum symbol on the activated pay line. However, since the maximum number of pull-in of the plum symbol is “0” (stop table A) or “1” (stop table B), the player will not win the FB prize unless the player operates the reel stop button at a predetermined timing. It becomes. However, even if the FB award is unsuccessful, the FB Bell, FB Watermelon, and FB Cherry roles are adopted for the small role awards such as the Bell Award, Watermelon Award, and Cherry Award. Can also receive medals. Moreover, since the plum symbol is drawn at the time of the first stop and the second stop, the player does not know which prize will be won until the last stop operation is performed. Thereby, the preference of the FB game can be improved.

  In an FB game, a lottery to determine whether or not to win the FB prize is executed, and if the FB prize is won, the plum symbol is stopped on the activated winning line in the first stop and the second stop. On the other hand, if the FB prize is unsuccessful, the reel may be controlled so as not to stop at the winning line in which the plum symbol is activated. For example, when the FB prize is won, the CPU 31 selects the stop table A or the stop table B at the third stop, while when the FB prize is not selected, the CPU 31 selects the stop table C and kicks the plum symbol. May be.

  In the above-mentioned example, the bell prize, the watermelon prize, and the cherry prize are adopted as the small prizes of the FB game. However, the stop symbol of the first stop and the second stop is “Plum”, and the third stop Even when the stop symbol is “white 7”, “red 7”, or “BAR”, a small role winning may be used. In this case, if it stops on the winning line where the plum symbol is activated in the first stop and the second stop, it is determined that a prize will be won at that time, and the payout is unknown at that time. Therefore, the fun of the game can be further enhanced.

  Next, the winning determination process of the base game, BB game, or CB game described above with reference to FIG. 27 will be described. In this process, by comparing the symbols on each active line of each stopped reel with the combination of symbols assigned to each award, it is sequentially determined whether or not a watermelon, bell, or cherry award was won. A determination is made (steps S140 to S141), and each part is controlled so as to pay out the number of medals corresponding to the winning prize with reference to the winning symbol combination table TBL3 (steps S143 to S145).

  Next, the CPU 31 determines whether or not it is a single RB win (step S146). If it is a single RB win, the medal is paid out (step S147), and further an RB game start process is executed (step S148). . FIG. 28 shows the contents of the RB start process. In this process, the CPU 31 sets an RB game in-progress flag (step S171) and sets the number of JAC winnings. For example, 8 times. Next, the CPU 31 sets the number of JAC games. For example, 12 times.

  If the determination condition is negative in step S146 of FIG. 27, the CPU 31 advances the process to step S149 to determine whether or not the BB winning is in BB. Specifically, the determination condition is affirmed when the BB game flag is set and the RB winning flag is set, and otherwise the determination condition is denied. If the determination condition is affirmed, the CPU 31 pays out medals assigned to the RB award (step S147) and executes an RB start process (step S151). Since the RB start process in step S151 is the same as that in step S148, description thereof is omitted.

  On the other hand, if the determination condition in step S149 is negative, the CPU 31 advances the process to step S155 and determines whether or not it is a single FB winning. Specifically, the determination condition is affirmed when the CB game flag is cleared and the FB winning flag is set, and otherwise the determination condition is denied. If the determination condition is affirmed, the CPU 31 pays out medals assigned to the FB prize (step S153) and executes the FB game start process. FIG. 29 shows the contents of the FB start process. In this process, the CPU 31 sets an FB game flag (step S173), and sets the number of FB games to “1” (step S174).

  If it is not a single FB winning, the determination condition in step S152 is denied, and the CPU 31 advances the process to step S155 to determine whether or not the FB winning is in CB (step S155). Specifically, the determination condition is affirmed when the CB game flag is set and the FB winning flag is set, and otherwise the determination condition is denied. If the determination condition is affirmed, the CPU 31 pays out medals assigned to the FB prize (step S156) and executes an FB game start process (step S157). Since the RB start process in step S151 is the same as that in step S148, description thereof is omitted.

  If it is not CB FB winning, the determination condition of step S155 is denied, and the CPU 31 advances the process to step S158 to determine whether or not the BB game is in progress (step S158). Specifically, the determination condition is affirmed when the BB game flag is set, and the determination condition is denied otherwise. When the determination condition is affirmed, the CPU 31 executes a BB game end determination process (step S159).

FIG. 30 shows the contents of the BB game end determination process. In this process, the CPU 31 determines whether or not a medal has been paid out (step S180). If there has been a medal payout, the CPU 31 adds the acquired number of games to the acquired number of BB games (step S181). If no medal is paid out in the game, the process of step S181 is omitted, and when the process of step S181 is completed, the CPU 31 advances the process to step S182 to determine whether or not the number of acquired medals exceeds a predetermined number. Determine. Here, the predetermined number X1 is X1 = Y1 where Y1 is the maximum number of sheets allowed for the entire BB game and Z1 is the maximum number of sheets that can be acquired in one game in the BB game (next one game). -Z1. In this example, the maximum number of coins allowed in the entire BB game is 465, and the maximum number of medals that can be earned in one game in the BB game is 15. Therefore, 450 sheets is a predetermined number.

  If the number of acquired medals exceeds 450 and the determination condition in step S182 is negative, the CPU 31 advances the process to step S183, and displays the number of acquired medals during the BB game (step S183). On the other hand, when the number of acquired medals exceeds 450, the BB game flag is cleared (step S184), and it is further determined with reference to the RB game flag whether the RB game is being played (step S185). ) If the RB game is in progress, the RB game flag is cleared (step S186). That is, when the acquired number exceeds the predetermined number, the BB game is ended. As a result, it is possible to make adjustments so as not to exceed the maximum number of sheets allowed for the entire BB game.

  Returning to FIG. If it is determined in step S158 that the BB game is not being played, the CPU 31 advances the process to step S160 to determine whether or not a BB prize has been won. When the BB prize is won, a predetermined number of medals are paid out (step S161), and a BB game start process is executed (step S162). FIG. 31 shows details of the BB game start process. As shown in the figure, the CPU 31 sets a flag during the BB game (step S187), and clears the acquisition number count during the BB game (step S188). Thereby, the accumulation of the number of acquisitions from the next game is executed.

  On the other hand, if it is determined in step S160 that it does not correspond to the BB winning, the CPU 31 advances the process to step S163 to determine whether or not the CB game is in progress. Specifically, the determination condition is affirmed when the CB game flag is set, and the determination condition is denied otherwise. When the determination condition is affirmed, the CPU 31 executes a CB game end determination process (step S164).

FIG. 32 shows details of the CB game end processing. As shown in the figure, the CPU 31 determines whether or not a medal has been paid out (step S190). If a medal has been paid out, the acquired number of games in the FB game is added (step S191). ). If no medal is paid out in the game, the process of step S191 is omitted. When the process of step S191 is completed, the CPU 31 advances the process to step S192 to determine whether the acquired medal number exceeds a predetermined number. Determine. Here, the predetermined number X2 is X2 = Y2 where Y2 is the maximum number of sheets allowed for the entire CB game and Z2 is the maximum number of sheets that can be acquired in one game in the CB game (next one game). -Z2. In this example, the maximum number of acquisitions allowed in the entire CB game is 253, and the maximum acquisition number that can be acquired in one game in the CB game is 15. Accordingly, 238 sheets are the predetermined number.

  If the number of acquired medals exceeds 238 and the determination condition in step S192 is negative, the CPU 31 advances the process to step S193 and displays the number of acquired medals during the CB game (step S193). On the other hand, if the number of acquired medals exceeds 238, the CB game flag is cleared (step S194), and it is further determined with reference to the FB game flag whether the FB game is in progress (step S195). ) If the FB game is in progress, the FB game flag is cleared (step S196). That is, when the acquired number exceeds the predetermined number, the CB game is ended. As a result, it is possible to make adjustments so as not to exceed the maximum number allowed for the entire CB game.

  Returning to FIG. If it is determined in step S163 that the CB game is not being played, the CPU 31 advances the process to step S165 to determine whether or not a CB winning is achieved. When a CB prize is won, a predetermined number of medals are paid out (step S166), and a CB game start process is executed (step S167). FIG. 33 shows details of the CB game start process. First, the CPU 31 sets a CB game flag (step S197), and clears the acquired number count during the CB game (step S198). Thereby, the accumulation of the number of acquisitions from the next game is executed.

  Next, the winning determination process (step S29 in FIG. 10) in the RB game will be described. FIG. 34 shows a detailed flowchart of the winning determination process in the RB game. First, the CPU 31 determines whether or not it is a JAC prize (step S200). If it is a JAC prize, a predetermined number of medals are paid out (step S201). It is determined whether the medal payout process ends, or if it is not a JAC prize, it is during the RB game (step S202). If the RB game flag is set, the CPU 31 determines that the RB game is being played, advances the process to step S203, and executes an RB game end determination process.

  FIG. 35 is a flowchart showing details of the RB game end determination process. As shown in the figure, the CPU 31 first determines whether or not it is a JAC prize (step S210). If it is a JAC prize, the JAC prize number is subtracted by "1" (step S211), and the number of JAC prizes is further increased. Is determined to be “0” (step S212). If the JAC winning number is “0”, the CPU 31 clears the RB game flag (step S217). On the other hand, if the JAC winning number is not “0”, the CPU 31 displays the remaining number of the JAC winning numbers (step S213), and subtracts the JAC game number by “1” (step S214). If the JAC prize is not won, the CPU 31 skips the processing from step S211 to step S213, and proceeds from step S210 to step S214. Thereafter, the CPU 31 determines whether or not the remaining number of JAC games is “0” (step S214). If it is “0”, the RB game flag is cleared (step S217), while it must be “0”. For example, the remaining number of JAC games is displayed (step S216).

  Returning to FIG. When the above-described RB game end determination process ends, or when the RB game flag is cleared and the determination condition in step S202 is negative, the CPU 31 sets whether the BB game is in progress or not. The determination is made with reference to (step S204). When the BB game flag is set, the CPU 31 determines that the BB game is being played, advances the process to step S205, and executes a BB game end determination process. On the other hand, if the BB game flag is cleared, the CPU 31 determines that the BB game is not in progress and ends the RB game winning determination process. Note that the BB game end determination process has already been described with reference to FIG.

  Next, the winning determination process in the FB game (step S30 in FIG. 10) will be described. FIG. 36 shows a detailed flowchart of the winning determination process in the FB game. First, the CPU 31 determines whether or not the FB prize is won (step S220), and if it is the FB prize, a predetermined number of medals are paid out (step S221).

  If the FB prize has not been won, the CPU 31 determines whether or not the FB small role prize has been won (step S222). The FB small role award is a small role award adopted in the FB game, and includes an FB bell role, an FB watermelon role, an FB cherry role, and the like. When winning the small bonus for FB, the CPU 31 pays out the number of medals corresponding to the winning prize (step S223). If the medal payout process ends, or if the determination condition in step S222 is negative without winning the FB small role award, the CPU 31 refers to the FB game flag to determine whether the FB game is in progress. Determination is made (step S224), and if the FB game is in progress, an FB game end determination process is executed (step S225). FIG. 37 shows a flowchart of the FB game end determination process. As shown in this figure, in the FB game end determination process, the FB game number is subtracted by “1” (step S230), and it is determined whether or not the remaining FB game number is “0” (step S231). If the number of FB games is “0”, the CPU 31 clears the FB game flag (step S232). As described above, since the number of FB games is set to one, the FB game does not continue in principle. However, when the FB prize lottery is executed during the FB game, the FB prize is won again in the FB game. Therefore, the FB game continues apparently. The unit of the FB game is the same as that of one game, and only the FB prize is won continuously.

  When the FB game end determination process ends or when the FB game is not in progress, the CPU 31 advances the process to step S226 to determine whether or not the FB prize is won. It executes (step S227). Since the FB game start process has already been described with reference to FIG. 29, the description thereof is omitted here. Next, it is determined with reference to the CB game flag whether or not the CB game is being played (step S228). If the determination condition is affirmed, a CB game end determination process is executed (step S229). Since the CB game end determination process has already been described with reference to FIG. 32, the description thereof is omitted here.

  FIG. 38 shows an example of progress of a series of games. In this example, in the base game and the CB game, an internal lottery is executed, and kicking control is executed according to the lottery result. That is, the reel is stopped with a delay from the operation timing of the reel stop button so that a combination other than the combination corresponding to the winning prize is not established. In other words, the establishment of a winning combination is normally prohibited, and reel stop control is executed that allows the winning combination corresponding to the winning prize to be established only when winning in the internal lottery. In this sense, the normal game and the CB game can be said to be internal lottery games that allow a winning combination to be formed according to the result of the internal lottery. On the other hand, the FB game can be said to be a non-internal lottery game that allows any combination to be established regardless of the result of the internal lottery.

  In this example, since the FB prize is won in the fourth normal game, the next game is the FB game FB0. The FB prize lottery is not executed in the FB game in the normal game. On the other hand, in the FB game in the CB game, the FB prize lottery is executed. Accordingly, the FB game in the normal game does not continue, but the FB game continues in the CB game. For example, since the 10th CB game has won the FB prize, the next game is the FB game FB1. In this example, since the FB game FB1 wins the FB prize, the next game also becomes the FB game FB2, and since the FB game FB2 also wins the FB prize, the next game also becomes the FB game FB3. .

  In this way, the FB game is originally completed in one game, but by executing the FB prize lottery during the FB game, the FB game can be apparently continuously executed. . In the FB game, the kick-off control is not executed, so the reel stop button is operated aiming at the symbol desired by the player. In the FB game in the CB game, it is possible to continuously win the FB game by operating the reel stop button aiming at the FB prize. Therefore, the number of continuous FB games is determined according to the skill of the player.

  Here, the lottery probability of the FB prize may be set higher in the CB game than in the base game as shown in FIG. Further, as shown in FIG. 5B, for the FB game in the CB game, the lottery probability may be set low as in the normal game and only the CB game may be set high. Also, the FB prize lottery may be executed in the FB game of the normal game. In this case, it is preferable that the lottery probability of the FB game in the normal game is set low as shown in FIGS.

  Next, the one-game end process (step S31 in FIG. 10) will be described. 40 and 41 are flowcharts showing the processing contents of one game end processing. The CPU 31 sequentially determines whether or not the replay winning flag, the watermelon winning flag, the bell winning flag, and the cherry winning flag are set (steps S240 to S243), and clears the set winning flags (steps S245 to S248). ). Next, the CPU 31 determines whether or not the BB winning flag is set (step S249). If the BB winning flag is set, the CPU 31 further determines whether or not the BB prize is won (step S250). If the BB winning flag is won, the BB winning flag is cleared (step S251). On the other hand, if no prize has been won, it is carried over to the next game without clearing the BB winning flag.

  Next, the CPU 31 determines whether or not the CB winning flag is set (step S252). If the CB winning flag is set, the CPU 31 further determines whether or not a CB prize has been won (step S253), and if it has won, the CB winning flag is cleared (step S254). On the other hand, if it is not won, it is carried over to the next game without clearing the CB winning flag.

  Next, the CPU 31 advances the processing to step S255 shown in FIG. 41, and determines whether or not the single RB winning flag is set (step S255). If the single RB winning flag is set, the CPU 31 further determines whether or not the RB prize has been won (step S256). If the single RB winning flag has been won, the single RB winning flag is cleared (step S257). . On the other hand, if no winning is made, it is carried over to the next game without clearing the single RB winning flag.

  Thereafter, the CPU 31 sequentially determines whether the RB winning flag during BB, the FB winning flag during CB, and the JAC winning flag are set (steps S258 to 260), and clears the set winning flag (step S261). ~ S263).

<5. Modification>
Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the invention is limited to the embodiments disclosed herein. However, the present invention can be changed as appropriate without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a gaming machine and a control method therefor are also included in the technical scope of the present invention. Must be understood as being. For example, the following modifications are naturally included in the present invention.

  (1) In the above-described embodiment, the lottery may be executed using the same lottery table in the internal lottery during the normal game and the FB game. In this case, the lottery table shown in FIG. 42 is adopted. During the normal game, the determination process is executed for all the lottery sections. However, for the FB game, the lottery sections of “BB”, “CB”, “RB”, and “FB” are combined into the lottery section of the FB prize. . During the FB game, the same processing steps as those of the base game are executed until the determination of the FB prize lottery classification, and the processing steps are omitted for the lottery classification from the first game to the incorrect selection and all are determined as “unfair”. do it. As a result, the lottery table can be shared and the internal lottery program can be shared, so that the ROM capacity can be reduced. In the normal game and the FB game, the same lottery table and the same determination processing step may be adopted, and in the FB game, the small role replay may be treated as unfair.

  (2) The embodiment described above relates to the slot machine, but the present invention can also be understood as a game program or a game machine imitating the slot machine described above. In this case, instead of the reels R1 to R3, the images of the reels R1 to R3 may be displayed on the display, and their operations may be controlled according to the game program. Further, the present invention can be applied to a video slot for displaying an image of a reel on a display such as a liquid crystal display device instead of the mechanical reels R1 to R3.

  (3) In the embodiment described above, the slot machine employs a medal as a game medium, but may employ a pachinko ball and a medal. In this case, the conversion number of medals and pachinko balls may be determined in advance, and the number of pachinko balls may be converted into the number of medals according to the conversion number and stored electronically as credits. For example, five pachinko balls may be assigned per medal.

  (4) In the above-described embodiment, the stop control in the FB game is performed by the CPU 31 detecting the operation order of the reel stop buttons, selecting the stop table according to the detected operation order, and using the selected stop table. In the first and second stop operations, the plum symbol is pulled in. However, the left reel R1 and the middle reel R2 perform the pull-in control of the plum symbol as in the first and second stop operations, and the right reel R3 is described above. You may perform stop control similar to 3rd stop operation.

  (5) In the above-described embodiment, “Plum-Plum-Bell”, “Plum-Bell-Plum”, and “Bell-Plum-Plum” may not be awarded in the FB game. In this case, “bell” is a non-winning symbol, but any symbol other than a plum symbol that is a symbol drawn in at the first stop and the second stop may be set as a non-winning symbol. However, since the bell symbols are arranged within the range of the maximum number of moving symbols allowed for the pull-in control in each reel R1 to R3, if a lottery is lost, it is possible to make sure that no winning is achieved. Become. In this case, a JAC game determination program can be employed for winning determination. The win in the JAC game is “-Plum”, but if you lose the JAC game, you can also use the stop table by selecting the stop table that has “-Bell” etc. on the winning line. In addition, a winning determination program including selection of a stop table can also be used. As a result, the storage capacity of the ROM 35 can be reduced.
