Description

  The present invention relates to a slot machine provided with a sub reel for production in addition to a main reel for determining a winning symbol.

  2. Description of the Related Art Conventionally, for example, there is a slot machine that includes a plurality of reels that variably display symbols according to a predetermined arrangement, and that generates a winning when a combination of symbols stopped and displayed by each reel is a predetermined winning symbol. As such a slot machine, there is one that gives a prize according to an internal winning combination determined by internal lottery. In a slot machine that determines an internal lottery combination, so-called pull-in control may be applied in which a reel is stopped within a predetermined time based on the operation point of a stop button. According to the pull-in control, if there is a symbol corresponding to the internal winning combination in the pull-in range corresponding to the predetermined time, the symbol can be pulled and stopped.

  In the slot machines as described above, winning of a role other than the internal winning combination is prohibited, but for example, some roles such as a replay role must be awarded when determined as an internal winning combination. Specifications may be set. In order to realize such specifications, it is necessary to appropriately set the symbol arrangement on the reel in relation to the pull-in control.

  However, in order to satisfy the above specifications, there is a possibility that the degree of freedom in design of the arrangement of symbols on the reel is hindered. If there is a restriction on the arrangement of symbols on the reels, it is difficult to set various stop patterns, which are combinations of stop symbols, and there is a possibility that effective production cannot be performed using the stop patterns. In view of this, there has been proposed a slot machine provided with a sub-reel for a production purpose that is not related to winning in addition to a main reel for determining a winning symbol (see, for example, Patent Document 1). There is also a proposal of a slot machine in which one of main reels in a normal slot machine is replaced with a sub reel and a small main reel is separately arranged. In such a slot machine, it is intended to realize an effective production using the sub reel by ensuring a high degree of freedom in design of the arrangement of symbols on the sub reel.

  However, the conventional slot machine has the following problems. In other words, the player may feel uncomfortable about the sub reel stop control different from the main reel stop control.

In the slot machine 1 of this example, which is a 3-bet dedicated machine, the start lever 62 is set to an effective state when a medal is inserted or when three bets are bet by operating the bet button 64.

The medal payout unit 54 is a payout unit that pays out medals to the medal tray 15 under the control of the control board 3.
The set value operation unit 68 is an operation unit for changing the set value for setting the winning probability of the bonus combination in six stages using the setting key 680.

  As shown in FIGS. 1 and 2, the control board 3 includes a CPU 31, ROM 33 and RAM 34 as memory means, an I / O unit 32 as an input / output interface, and a random number extraction unit that extracts random numbers for internal lottery. 35. The CPU 31 executes a software program read from the ROM 33 to thereby determine a winning symbol 49 for determining a winning symbol, a determination symbol display controller 45 for controlling the main reels 21b to d, and an internal lottery for lottering an internal winning combination. 42, the winning flag control means 41 for controlling the internal winning flag, and the profit granting means 40 for granting a profit corresponding to the winning symbol to the player.

  As shown in FIG. 1, the ROM 33 as the memory means is a winning random number table (not shown) used by the internal lottery means 42 for lottery of the internal winning combination, and a stop used for stop control (drawing control) of the main reels 21b to 21d and the sub reel 23. A table (FIG. 7) is stored. The winning random number table is a data table that defines winning random numbers for each winning combination. The winning random number table is prepared for each set value and each gaming state. In the slot machine 1, by switching the winning random number table applied to the lottery of the internal winning combination for each set value, the internal winning probability of at least one of the combinations is changed for each set value.

  As illustrated in FIG. 7, the stop table is a data table that defines the number of drawn symbols for the symbols 20 and 230 arranged on the main reel 21 and the sub reel 23. The number of drawn symbols is a variable number of symbols until the corresponding main reel 21 or sub reel 23 is actually stopped when the stop button 61 is operated at the moment when the corresponding symbol is positioned on the winning line 213. In the drawing, the sub reel 23 is displayed as “sub”, the normal main reel 21b as “through b”, the normal main reel 21c as “through c”, and the specific main reel 21d as “special d”. A plurality of stop tables are set according to the internal winning flag, the operation order of the stop buttons 61L, C, and R, and the operation timing of the stop buttons 61L, C, and R.

  FIG. 7 illustrates a stop table that is applied when the stop button 61 is operated in the order of left → middle → right with the internal winning flag for the cherry role being established. In the figure, the symbol numbers (see FIG. 5) of each main reel 21 and sub reel 23 are displayed in the left column, and the number of drawn symbols is displayed in the right column. FIG. 9A is a stop table applied when the symbol “cherry” can be pulled in the specific main reel 21d and the sub reel 23 in accordance with the operation of the stop button 61L. FIG. 5B is a stop table applied when the symbol “cherry” can be drawn in the specific main reel 21d in response to the operation of the stop button 61L, while the symbol “cherry” cannot be drawn in the sub reel 23. is there. FIG. 10C is a stop table applied when the symbol “cherry” cannot be pulled in the specific main reel 21d in accordance with the operation of the stop button 61L. The contents of the stop control of each reel using the stop table of FIG. 7 will be described in detail later with a specific example.

  As shown in FIG. 1, the random number extraction unit 35 is a part that extracts a random number for internal lottery. The random number extraction unit 35 extracts a random number from the integers generated by the random number generation unit 350. The random number generator 350 is a part that generates an integer belonging to the range of 0 to 65535 (decimal number display). The random number extraction unit 35 samples an integer generated by the random number generation unit 350 using a game start signal corresponding to the operation of the start lever 62 as a trigger (trigger), and extracts it as a random number for internal lottery. The random number extracted by the random number extraction unit 35 becomes a random number for internal lottery for the internal lottery means 42 to draw the internal winning combination.

  As shown in FIG. 1, the internal lottery means 42 is a means for determining an internal winning combination based on the random number extracted by the random number extraction unit 35. The internal winning combination that can be determined by the internal lottery means 42 of this example is seven types of two types of BIG bonus combination, REG bonus combination, bell combination, watermelon combination, cherry combination and replay combination as described above with reference to FIG. One of the roles.

  As shown in FIG. 1, the winning flag control means 41 is a means for controlling an internal winning flag indicating a state where each winning combination can be won. The winning flag control means 41 switches off an internal winning flag such as a small role including a replay role before starting the next game regardless of whether or not a winning is made in a game in which the internal winning flag is established for the first time. . On the other hand, the bonus flag corresponding to the bonus combination is carried over to the next game until winning, and is switched off according to the bonus combination winning. By such control of the winning flag control means 41, a small part including a replay part that has not won a prize in an internally won game is so-called missing. On the other hand, once the bonus combination is won internally, the bonus confirmed state can be maintained until winning.

  As shown in FIGS. 1 and 2, the determination symbol display control means 45 starts symbol variation of the main reel 21 in response to the variation start signal, and performs symbol variation of the main reel 21 in response to the variation stop signal. It is a means to stop. The determination symbol display control means 45 inputs a control pulse to the stepping motor constituting the main reel drive unit 22 and rotates the stepping motor by one step for each pulse. The determination symbol display control means 45 counts the number of control pulses input to the main reel drive unit 22, that is, the number of steps rotated by the stepping motor. In particular, the determination symbol display control means 45 of this example counts the number of steps generated after the most recent detection signal by resetting the number of steps to zero each time the detection signal of the reference position piece of each main reel 21 is fetched. is doing.

  As shown in FIG. 1, the determination symbol display control means 45 stops the symbols within a predetermined pull-in range determined by rules (rules concerning the recognition of game machines and type tests, etc.) on the winning line. It is a means to implement. In this example, a range corresponding to 4 symbols is set as the pull-in range. The determination symbol display control means 45 calculates a bita symbol, which is the symbol 20 instantaneously located on the winning line 213, based on the number of steps when the fluctuation stop signal is received, and the bitter symbol is stored in the stop table. To match. Then, the number of drawn-in symbols defined corresponding to the bitter symbol is acquired, the number of drawn-in symbols is drawn in, and the main reel 21 is stopped.

  The effect symbol display control means 251 is a means for starting the symbol variation of the sub reel 23 in response to the variation start signal and stopping the symbol variation of the sub reel 23 in response to the variation stop signal. The effect symbol display control means 251 stops the sub reel 23 in accordance with the determination symbol that is stopped and displayed on the specific main reel 21d. When the winning symbol corresponding to the internal winning flag can be stopped and displayed on the specific main reel 21d and the normal main reels 21b, c, the effect symbol display control means 251 performs the effect design 230 of the type corresponding to the internal winning flag. The symbol to be stopped and displayed on the sub reels 23 is changed depending on whether or not can be stopped and displayed.

  When the symbol 230 corresponding to the internal winning flag can be stopped and displayed on the sub reel 23, the winning symbol corresponding to the internal winning flag in the specific display area 111 is displayed together with the stopped symbols of the normal main reels 21b and 21c to be stopped thereafter. The sub reels 23 are stopped so that can be displayed as stopped. On the other hand, when the symbol 230 corresponding to the internal winning flag cannot be stopped and displayed on the sub reel 23, the symbols other than the winning combination in the specific display area 111 are displayed together with the stopped symbols of the normal main reels 21b and c to be stopped thereafter. The sub reel 23 is stopped so that the winning symbol can be stopped and displayed.

  The effect symbol display control means 251 controls the sub reel 23 in the same manner as the control of the main reel 21 by the determination symbol display control means 45. In the slot machine 1 of this example, as the main reel 21, a range corresponding to four symbols is set as the pull-in range of the sub reel 23.

  As shown in FIGS. 1 and 2, the winning determination means 49 is a means for determining whether or not the combination of the determination symbols 20 displayed on the normal main reels 21b and 21d and the specific main reel 21d is a winning symbol. is there. Specifically, the winning determination means 49 determines whether or not the combination of the determination symbols 20 stopped on the winning lines 211 to 215 set so as to cross the main reels 21b to 21d is a winning symbol. And determine the winning combination. The winning determination means 49 captures the number of steps counted by the determination symbol display control means 45 for each stepping motor constituting the main reel drive unit 22 after the main reels 21b to 21d are stopped. Based on the number of steps, the winning determination means 49 obtains the type of the determination symbol 20 stopped on the winning lines 211 to 215, and determines whether or not a winning combination is established for the combination of the determination symbols 20. judge. The winning determination means 49 outputs a winning signal indicating that the winning of the internal winning combination has been confirmed or a non-winning signal indicating that the loss has been confirmed to the sub reel control board 250. Note that the winning signal or the non-winning signal is output immediately when winning or losing is confirmed even before all the main reels 21b to 21d are stopped.

  As shown in FIGS. 1 and 3, the profit granting means 40 is a means for giving a profit according to the type of winning combination determined by the winning determination means 49. For example, when the small combination is a winning combination, a predetermined number of medals defined as shown in FIG. 3 are paid out. On the other hand, when the BB combination is a winning combination, a profit of starting a BIG bonus game (BB game) is given. Further, when the replay role is a winning role, a benefit of enjoying the next game for free is given.

  Next, the pull-in control of the main reels 21b to 21d and the sub reel 23 in the slot machine 1 of this example will be described with reference to FIGS. Here, three types of pull-in control patterns based on the stop table shown in FIG. 7 will be described in the case where the left stop button 61L is first operated under the establishment of the internal winning flag for the cherry role.

  First, a description will be given of a pull-in control pattern when the symbol “cherry” is included in the pull-in range in the specific main reel 21 d and the symbol “cherry” is included in the pull-in range in the sub reel 23. In this case, the symbol “cherry” is drawn and stopped in the symbol display area 110d and the symbol display area 110a. For example, as shown in FIG. 7A, when the left stop button 61L is operated at the moment when the symbol “Cherry” of symbol number 13 is positioned at the symbol position d0 of the symbol display area 110d, the specific main reel 21d is bitter. It stops and the symbol “cherry” is stopped and displayed in the symbol display area 110d. On the other hand, with respect to the sub reel 23, for example, when the left stop button 61L is operated at the moment when the symbol “black 7” of the symbol number 13 is positioned at the symbol position a2 in the middle of the symbol display area 110a, two symbols are drawn. The symbol “cherry” of symbol number 15 is stopped and displayed at the symbol position a2.

  Next, a drawing control pattern when the symbol “cherry” is included in the drawing range in the specific main reel 21 d but the symbol “cherry” is not included in the drawing range in the sub reel 23 will be described. In this case, the symbol “cherry” stops in the symbol display area 110d, while the symbol “bell” stops in a straight line in the specific display area 111 including the symbol display areas 110a to 110c. For example, as shown in FIG. 7B, when the left stop button 61L is operated at the moment when the symbol “cherry” of symbol number 13 is positioned at the symbol position d0 in the symbol display area 110d, As with, the symbol “cherry” can be stopped at a bitter stop. For the sub reel 23, for example, when the left stop button 61L is operated at the moment when the symbol “R” of the symbol number 8 is positioned at the symbol position a2, the symbol “bell” having the symbol number 10 is pulled in by two symbols. Stops at the symbol position a2.

  Further, with respect to the normal main reel 21b, for example, when the left stop button 61L is operated at the moment when the symbol “BAR” of the symbol number 12 is located at the symbol position b2, as shown in FIG. As a result, the symbol “bell” of symbol number 14 stops at the symbol position b2. For the normal main reel 21c, for example, when the left stop button 61L is operated at the moment when the symbol “black 7” of symbol number 13 is located at the symbol position c2, three symbols are drawn as shown in FIG. Then, the symbol “bell” of symbol number 16 stops at the symbol position c2. In this way, the symbols “bells” are aligned in the horizontal direction in the specific display area 111.

  Next, a drawing control pattern when the symbol “cherry” is not included in the drawing range of the specific main reel 21d will be described. In this case, the pull-in control is performed as shown in FIG. 7C, the symbol “cherry” is not stopped and displayed in the symbol display area 110d and the symbol display area 110a, and the same kind of symbol is displayed in the specific display area 111. Will never stop.

  Next, the operation of the slot machine 1 of this example configured as described above will be described with reference to the flowcharts of FIGS. FIG. 8 is a flowchart showing an operation flow of the slot machine 1 of this example. FIG. 9 is a flowchart showing the flow of the game start process P1 in the slot machine 1 of this example. 10 and 11 are flowcharts showing the flow of reel stop processing P21 and P22 for stopping the main reel 21 or the sub reel 23. FIG. FIG. 12 is a flowchart showing the flow of the winning process P3 in the slot machine 1 of this example.

  First, the overall processing flow in the slot machine 1 of this example will be described with reference to FIG. As shown in the figure, in the slot machine 1 of this example, the game start process P1 (FIG. 9), the reel stop process P2 (FIGS. 10 and 11), and the winning process P3 (FIG. 12) are performed in this order. The

  In the game start process P1, as shown in FIG. 9, it is first determined whether or not a game start operation has been detected (step S101). When a game start operation is detected, a random number for internal lottery is acquired as in step S102, and collation is performed on the winning random number table as in step S103. In step S104, 1 (ON state) is set as the flag value of the internal winning flag corresponding to the internal winning combination. Thereafter, the rotation of the reels 21 and 23 is started as in step S105.

  Of the reel stop process P2, the flow of the reel stop process P21 of the main reel 21 will be described with reference to FIG. In the main reel stop process P21, it is first determined whether or not an operation of the left stop button 61L is detected as in step S201. When the operation of the left stop button 61L is detected, it is determined whether or not the symbol “cherry” is within the pull-in range on the specific main reel 21d as in step S202. When the symbol “cherry” is within the pull-in range on the specific main reel 21d, a winning signal indicating that the winning of the cherry role has been confirmed is output to the sub reel control board 250 (step S203), and the symbol display area The symbol “cherry” is pulled into 110d and stops (step S204).

  On the other hand, when the symbol “cherry” is not within the pull-in range on the specific main reel 21d (step S202), a non-winning signal indicating that the non-winning of the cherry role has been confirmed is output (step S210) and the symbol “cherry” Symbols other than “cherry” are drawn into the symbol display area 110d and stopped (step S211).

  Of the reel stop process P2, the flow of the reel stop process P22 of the sub reel 23 will be described with reference to FIG. In the sub-reel stop process P22, first, as shown in step S301, it is determined to receive a winning signal indicating that the winning of the cherry role has been confirmed. When the winning signal is received, the process proceeds to step S302, and it is determined whether or not the symbol “cherry” is within the drawing range in the sub reel 23. When the symbol “cherry” is within the pull-in range on the sub reel 23, the symbol “cherry” is pulled into the symbol display area 110a and stops as in step S303. On the other hand, when the symbol “cherry” is not within the pull-in range in the sub reel 23 (step S302), the symbol “bell” is pulled into the symbol display area 110a and stopped as in step S310.

  If the winning signal is not received in step S301, it is determined whether or not a non-winning signal indicating that the cherry role is not won is determined as in step S320. When the non-winning signal is received, symbols other than the symbol “cherry” are drawn into the symbol display area 110a and stopped (step S321).

  The flow of the winning process P3 will be described with reference to FIG. In the winning process P3, first, it is determined whether or not a winning symbol is established along any of the winning lines 211 to 215 as in step S401. When the replay combination is won (step S402), a replay game is set (step S403). When winning the BB combination (step S410), the BB combination flag that is the internal winning flag of the BB combination is reset (step S411), and the BB game flag corresponding to the BB game is set to the on state (step S412). ) If the RB combination is won (step S420), the RB combination flag that is an internal winning flag of the RB combination is reset (step S421), and the RB game flag corresponding to the REG bonus game (RB game) is on. Is set (step S422). When any small combination wins (Step S430), a medal payout process P4 is performed.

  Thereafter, the process proceeds to step S404, and the internal winning flag corresponding to the replay combination and the small combination is reset to the off state. In the subsequent step S405, it is determined whether or not the BB game end condition (the number of payouts of 465) has been achieved. When the BB game end condition is achieved, the BB game flag is reset to the OFF state as in step S406. Further, in step S407, it is determined whether or not the RB game end condition (12 game digest or 8 game winning) has been achieved. If the RB game end condition is achieved, the RB game flag is reset to the OFF state as in step S408.

  As described above, according to the slot machine 1 of the present example, various effects using the sub reel 23 can be realized while suppressing the uncomfortable feeling that the player can feel due to the sub reel 23. That is, in the slot machine 1 of this example, when a medal is paid out in accordance with the winning, the winning symbol of any combination can be stopped and displayed by the sub reel 23 and the normal main reels 21b, c. Therefore, in this slot machine 1, the uncomfortable feeling that the player can feel due to the situation where a winning occurs despite the fact that the winning symbol is not stopped by the sub reel 23 and the normal main reels 21b, c is suppressed. ing.

In the slot machine 1 of this example, the specific main reels 21d are arranged in a horizontal row with respect to the normal main reels 21b and c. Instead, the specific main reels 21d are arranged above the specific display area 111 or It is also possible to arrange it on the lower side.
Further, the specific main reel 21d is not limited to the one having a rotation axis that is substantially coaxial with the rotation axes of the other reels 21b, 21c, and 23, as in this example. For example, the axis direction of the rotating shaft is the horizontal direction, like the other rotating shafts, while the rotating axis is deviated from the rotating shafts of the other reels. May be different specific main reels. Further, the specific main reel may have a different reel diameter from the other reels.

In addition, unlike the configuration of the slot machine 1 of this example, a slot machine in which a plurality of roles can be internally won at the same time may be used. In this case, a stop table may be set for each combination of a plurality of winning combinations.
Further, in the slot machine 1 of this example, the sub reel control board 250 independent from the control board 3 is adopted, but instead, the function of the sub reel control board 250 can be included in the control board 3.
