The game player continuously presses a first stop button until the operation is validated, and after the validation of the operation, the respective stop buttons are operated in the order of a second stop button and a third stop button at intervals of predetermined time, thereby arranging in order "RED 7" on a prize effective line to put the BB in winning state. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a slot machine used in a game hall such as a pachinko parlor.

  In general, the slot machine includes three reels having a plurality of types of symbols arranged on the outer periphery, and three stop buttons provided corresponding to each reel. In the slot machine, as the game starts, the three reels start to rotate all at once, and the winning combination lottery is executed to determine one of a plurality of types or a loss.

  In addition, in the slot machine, when the rotation family of each reel reaches a preset constant speed, the operation of each stop button is activated, and when the operation-enabled stop button is pressed, the corresponding reel The rotation is stopped. When all reels are stopped and the symbol corresponding to the winning combination won in the winning combination lottery is displayed on the winning line, the winning combination is won, and processing corresponding to the winning winning combination is executed. Is done.

  As a winning combination, for example, when winning a prize, it shifts to a mode that is more advantageous to the player than the normal mode, such as a bonus mode, AT (assist time) mode, RT (replay time) mode, ART (assist replay time) mode An advantageous mode transition combination, a small combination in which medals are paid out, a replay that enables the next game without insertion of medals, and the like are provided. Also, some slot machines are configured to return from the advantageous mode to the normal mode when a specific small combination wins during the advantageous mode described above.

  However, a player who is not good at winning a prize cannot win a winning mode transition role even though he has won the winning role lottery, or unintentionally plays a specific small role during the advantageous mode. It could be a prize and it was a problem. Also, even players who are good at winning cannot win the advantageous mode transition combination due to carelessness, or unintentionally win a specific small role during the advantageous mode In some cases. For this reason, Patent Document 1 below describes an example in which a pressing operation of a stop button is validated at a timing when a symbol that is advantageous to the player stops on the winning effective line.

JP 2006-230806 A

  However, in Patent Document 1, if the operation is not performed while the operation of the stop button is activated, it takes time to wait until the next operation is activated. In addition, in order to operate the stop button reliably when the operation of the stop button is enabled, it is necessary to repeatedly hit the stop button, and it is necessary to perform such repeated hits for all the stop buttons. Therefore, there was a problem that it took time and effort.

  The present invention has been made in view of the above background, and an object thereof is to provide a slot machine that can easily stop a symbol (setting symbol) that is advantageous to a player without taking time and effort. It is another object of the present invention to provide a slot machine that can easily stop a symbol (setting symbol) that is disadvantageous for a player without taking time and effort.

  In order to achieve the above object, a slot machine of the present invention includes a plurality of reels having a plurality of types of symbols arranged on the outer periphery, reel rotation control means for starting rotation of all the reels at the start of a game, A plurality of stop buttons provided corresponding to the reels, the corresponding reels stop rotating as each stop button is operated, and the symbols displayed on the winning line when all reels stop In the slot machine that performs processing according to the combination of the above, the setting symbols that are activated at the start of the game and that are set for each reel are stopped when the stop buttons are operated in a predetermined order. Reel rotation position adjusting means for adjusting the rotation position of each reel so as to be positioned at a rotation position shifted by a predetermined number of frames between the reels, After the reel rotation position adjusting means completes the adjustment of the rotation positions of all the reels, all the reels are rotated at the same speed while maintaining the adjusted rotation positions. During the adjustment of the rotation position of the reel, there is provided stop operation invalidating means for invalidating at least the operation of the stop button corresponding to the reel being adjusted.

  When the stop button is operated, it is provided with a reel stop control means for drawing and stopping any of the symbols existing within a predetermined pull-in range on the winning line, and the reel rotation position adjusting means includes The adjustment may be performed so that the specific symbol of the reel corresponding to the operated stop button exists within the pull-in range when operated in the predetermined order every predetermined time.

  Further, the stop operation invalidation means invalidates all stop buttons when a set symbol of a reel that is initially stopped when the stop buttons are operated in the predetermined order reaches the pull-in range. May be canceled all at once.

  According to the present invention, when each stop button is operated every predetermined time in a predetermined order, when the set symbol is displayed on the winning line when the first reel is stopped, the remaining reels are stopped. In some cases, the set symbols are displayed on the winning line. Further, if the set symbols are not displayed on the winning effective line when the first reel is stopped, the set symbols are not displayed on the winning effective line even when the remaining reels are stopped. As described above, according to the present invention, by paying attention to the operation timing of the stop button when the reels are first stopped, the symbols (setting symbols) advantageous to the player are easily aligned on the winning line. Or, it is possible to prevent the symbols (setting symbols) that are disadvantageous for the player from being arranged on the winning line.

  Furthermore, if the rotation position of each reel is adjusted so that the set symbol is within the pull-in range, the rotation position of each reel is adjusted so that the set symbol is shifted by the number of fixed frames. Thus, it is possible to obtain an effect that the degree of freedom of the symbol arrangement of each reel and the degree of freedom of adjustment of the rotational position are increased.

  In addition, when the set symbols of the reels that are initially stopped when the stop buttons are operated in a predetermined order reach the pull-in range, if all the stop buttons are disabled at the same time, the first operation is performed. By repeatedly hitting the stop button, the set symbols can be surely aligned on the winning line. In addition, only the stop button to be operated first is repeatedly hit, and the subsequent stop buttons are operated at predetermined intervals so that the set symbols can be aligned on the winning line, so it is set by repeatedly hitting all stop buttons. Compared with the configuration in which the symbols can be aligned on the winning effective line, the set symbols can be easily aligned on the winning effective line.

It is an external view of a slot machine. It is a block diagram which shows the outline of the electrical structure of a slot machine. It is a flowchart which shows the procedure in which a rotation position adjustment process is performed. It is explanatory drawing which shows the state of each reel after a rotation position adjustment process. It is a flowchart which shows the procedure in which operation of a stop button is validated.

  As shown in FIG. 1, the slot machine 10 includes a storage box 12 and a front door 14. The storage box 12 stores a reel unit, a hopper device, and the like. The front door 14 is vertically divided into an upper door 14a and a lower door 14b. The upper door 14a and the lower door 14b are respectively pivotally attached to the storage box 12 and supported so as to be freely opened and closed.

  The upper door 14a is provided with a speaker 15, a liquid crystal display 16, and a display window 18. The speaker 15 outputs various effect sounds. The liquid crystal display 16 displays various effect images. The slot machine 10 produces a game by controlling the speaker 15 and the liquid crystal display 16.

  In the back of the display window 18, a first reel 20a, a second reel 20b, and a third reel 20c that are rotatable are provided. A plurality of types of symbols are arranged on the outer peripheral surfaces of the reels 20a to 20c, and three symbols per reel are displayed through the display window 18 when the reels 20a to 20c are stopped. In the slot machine 10, a total of five payable effective lines 22, consisting of three laterally and two diagonally, are set. And when each reel 20a-20c stops, it is alert | reported whether the winning combination won by the combination of the symbol stopped on the winning effective line 22.

  The lower door 14b has a medal slot 24 for inserting medals, a start lever 26 that is operated when a game is started, a first stop button 30a for stopping the rotating reel, a second stop button 30b, A third stop button 30c, a payout port 32 for paying out medals, and a medal tray 34 for receiving medals paid out from the payout port 32 are provided.

  The slot machine 10 can be played once by betting three medals, and when three medals are inserted into the medal slot 24, the three medals are bet and the start lever 26 is activated. When the activated start lever 26 is operated, the game is started accordingly.

  When the game is started, a winning combination lottery is performed to determine one of a plurality of types of winning combinations or a loss, and the reels 20a to 20c start to rotate at the same time. Thereafter, when the stop buttons 30a to 30c are activated and the activated stop buttons 30a to 30c are operated, the rotation of the corresponding reels is individually stopped. Then, when all the reels are stopped, one game is finished. As a result of this game, when the winning combination determined by the winning combination lottery wins, a process associated with the winning winning combination is executed. .

  The slot machine 10 is provided with replay, small role, and BB (Big Bonus) as winning combinations. The replay is determined by the winning combination lottery (winning the winning combination lottery), and when the symbol “Replay” is aligned on the winning line 22, the winning combination is won. When the replay wins, the next game is possible without betting medals.

  Plural kinds of small combinations are set, and when a winning combination lottery is won and the symbols corresponding to the selected small combinations are aligned on the winning line 22, the winning combination is won. When the small combination wins, the number of medals corresponding to the type of the small combination won is paid out from the payout slot 32 to the medal tray 34. These small roles and the above-mentioned replays will lose the right to win if the winning combination lottery cannot be won in the game that was won.

  BB is won when the winning combination lottery is won and the symbol “red 7 (set symbol)” is aligned on the winning effective line 22. Unlike the replays and small roles described above, even if the BB cannot be won in the game in which the winning combination lottery is won, the right to win in the next and subsequent games is carried over. When BB wins, it shifts to BB mode (bonus mode). In the BB mode, the payout rate (ratio of medals paid out per bet medal) is higher than in the normal mode, and a large number of medals can be obtained. The BB mode is terminated when a preset termination condition (a predetermined number of medals are acquired, a predetermined number of games are executed, etc.) is satisfied, and the BB mode is shifted to the ART mode (special mode) after the BB mode is terminated.

  The ART mode is a mode in which the winning probability of replay is set high, and when a predetermined small combination is won, the type of the small combination is displayed on the liquid crystal display 16 and notified. For this reason, in the ART mode, not only can the game be performed while suppressing the consumption of medals, but also the medal can be increased efficiently by preventing the predetermined small part from being missed. The ART mode is terminated when a predetermined number of games are performed, and thereafter, the normal mode is entered. Also, the ART mode ends when the BB wins, that is, when the BB wins in the winning combination lottery and the symbols “red 7” are aligned on the winning effective line 22 without waiting for the predetermined number of games to be executed. Then, the mode is shifted to the BB mode.

  As described above, in the slot machine 10, if the symbol “red 7” is aligned on the winning winning line 22 during the normal mode, the player shifts to the BB mode, which is advantageous to the player. On the other hand, if the pattern “red 7” is aligned on the winning pay line 22 during the ART mode, the ART mode ends without playing a predetermined number of games, which is disadvantageous for the player.

  As shown in FIG. 2, a control unit 50 that centrally controls the slot machine 10 is provided inside the slot machine 10. In addition to the winning combination determination unit 51 that performs the above-mentioned winning combination lottery, the control unit 50 is connected to a memory 52, a medal sensor 54, a start signal sensor 56, a stop signal sensor 58, and a reel drive controller 60. Further, the control unit 50 is provided with a reel rotation control unit (reel rotation control unit, reel rotation position adjustment unit) 62 and a reel stop control unit (reel stop control unit, stop operation invalidating unit) 64.

  The memory 52 stores various setting information such as game execution programs and execution data. The control unit 50 controls driving of each unit of the slot machine 10 based on information stored in the memory 52. The memory 52 is used for temporary storage or rewriting of data such as a winning flag (a flag indicating the type of winning combination won in the winning combination lottery) used for each game. When any winning combination is won in the winning combination lottery, the control unit 50 writes a winning flag corresponding to the winning combination in the memory 52, and also writes a winning flag corresponding to replay or small combination when the game ends. If they have been deleted, they are erased from the memory 52.

  The medal sensor 54 detects an appropriate medal inserted from the medal insertion slot 24 and inputs a medal detection signal to the control unit 50. The start signal sensor 56 detects that the start lever 26 has been pressed, and inputs a start signal to the control unit 50. The stop signal sensor 58 detects that the stop buttons 30 a to 30 c are pressed, and inputs a stop signal to the control unit 50. The reel drive controller 60 includes stepping motors (not shown) connected to the reels 20a to 20c, and drives the stepping motors under the control of the control unit 50 to rotate or stop the reels 20a to 20c. .

  The control unit 50 counts the number of medals inserted into the medal insertion slot 24 based on the medal detection signal, and validates the operation of the start lever 26 when three medals are inserted. After the start lever 26 is activated, a game is started when a start signal is input. The control unit 50 activates the reel rotation control unit 62 and the reel stop control unit 64 after operating the winning combination determining unit 51 and starting the winning combination lottery with the start of the game.

  As shown in FIG. 3, the reel rotation control unit 62 checks whether a winning flag corresponding to BB is written in the memory 52 in accordance with the operation. If the winning flag corresponding to BB is not written in the memory 52, that is, if the BB is not won in the current game and there is no BB that has been won, the reel drive controller 60 is used. After driving the reels 20a to 20c and starting the rotation of the reels 20a to 20c all at once, all the reels 20a to 20c are rotated at the same speed (in this example, rotating at a rate of 28 frames per second). Rotate.

  On the other hand, when the winning flag corresponding to BB is written in the memory 52, that is, when BB is won in the current game, or when BB is won in the previous game and the winning is carried over, the reel The rotation control unit 62 drives each of the reels 20a to 20c via the reel drive controller 60 and performs a rotation position adjustment process, which will be described later, and then maintains all the reels 20a to 20c while maintaining the adjusted rotation position. Rotate at the same speed.

  As shown in FIG. 4, in the rotational position adjustment process, the reel rotation control unit 62 determines that “red 7” of the second reel 20b is behind the “reel 7” in the rotation direction of the reel than “red 7” of the first reel 20a. (5 frames in this example), and further, each “red 7” of the third reel 20c is shifted by the predetermined number of frames toward the rear side in the rotation direction of the reel from “red 7” of the second reel 20b. The rotational positions of the reels 20a to 20c are adjusted. In FIG. 4, an area surrounded by a broken line is an area where a frame of symbols is arranged, and an arbitrary symbol is arranged in an area other than “red 7”. The description is omitted.

  As described above, after the winning combination lottery, whether or not the rotational position adjustment processing is performed is different, but in any case, the rotation of the reels 20a to 20c is started. As described above, the reel stop control unit 64 is operated after the winning combination lottery, that is, simultaneously with the start of rotation of the reels 20a to 20c. The reel stop control unit 64 operates in two operation modes, a stop operation acceptance mode and a stop operation invalidation mode, and corresponds to the operated stop button when a stop signal is input during the stop operation acceptance mode. The reel stop control is performed.

  In the stop control by the reel stop control unit 64, known pull-in control is performed. In the pull-in control, the number of pull-in frames required from when the stop button is operated until the corresponding reel stops is in a range of 0 to 4 frames including the symbols on the winning line 22, that is, a range of 5 frames (hereinafter referred to as “draw-in”). Range)) is set as the upper limit. If the winning symbol (the symbol corresponding to the winning combination determined in the winning combination lottery) is included in the reel pull-in range corresponding to the stop button being operated, this winning symbol is the winning winning line 22. Stopped on.

  As shown in FIG. 5, the reel stop control unit 64 shifts to a stop operation invalidation mode (simultaneously with the start of rotation of the reels 20a to 20c) (the operation of each stop button 30a to 30c is invalid). ). Thereafter, the reel stop control unit 64 checks whether or not the rotational position adjustment processing has been performed when all the reels 20a to 20c reach the same speed. Then, when the rotational position adjustment processing is not performed, the operation shifts to the stop operation reception mode (operations of the stop buttons 30a to 30c are validated).

  On the other hand, when the rotational position adjustment process is performed, the reel stop control unit 64 checks whether the current mode is the normal mode or the ART mode. When the current mode is the normal mode, when the “red 7” of the first reel 20a moves from the outside of the pulling range to the pulling range, the mode is shifted to the stop operation receiving mode. Further, when the current mode is the ART mode, when the “red 7” of the first reel 20a moves out of the pull-in range and out of the pull-in range, the mode shifts to the stop operation acceptance mode.

  As described above, in the slot machine 10, when BB is won in the normal mode, after the rotational position adjustment processing is performed, all the reels 20a to 20c are rotated at the same speed, and thereafter, the reels of the first reel 20a are rotated. When “red 7” moves into the pull-in range, the operation of the stop buttons 30a to 30c is validated (the reel stop control unit 64 shifts to the stop operation reception mode), and the reels 20a to 20c can be stopped. It becomes a state.

  In this example, when the rotational position adjustment process is performed, “red 7” is shifted from the first reel 20a to the third reel 20c by 5 symbols on the rear side in the reel rotation direction. In this example, since the same speed is a speed of rotating 28 symbols per second, the time required for a reel rotating at this same speed to rotate 5 symbols is about 0.18 seconds (1 ÷ 28 × 5 (seconds)). Therefore, when the reels 20a to 20c are rotated at the same speed after the rotational position adjustment processing is performed, the second red is about 0.18 seconds after the “red 7” of the first reel 20a moves into the pull-in range. “Red 7” of the reel 20 b moves into the pull-in range, and further, “Red 7” of the third reel 20 c about 0.18 seconds after the “red 7” of the second reel 20 b moves into the pull-in range. Moves into the pull-in range.

  Therefore, when BB is won during the normal mode, the player repeatedly hits the first stop button 30a until the operation is activated, and after the operation is activated, the player stops the second stop button every 0.18 seconds. By operating the 30b and the third stop button 30c, “red 7” can be aligned on the winning line 22 (BB is awarded).

  Further, in the slot machine 10, when BB is won during the ART mode, after the rotational position adjustment processing is performed, all the reels 20a to 20c are rotated at the same speed, and thereafter, the “red” of the first reel 20a is “red”. When “7” moves out of the pull-in range, the operation of the stop buttons 30a to 30c is validated, and the reels 20a to 20c can be stopped. For this reason, when BB is won during the ART mode, the player repeatedly hits the first stop button 30a until the operation is activated, and the second stop button 30b every 0.18 seconds after the operation is activated. By operating the third stop button 30c, it is possible to prevent “Red 7” from being aligned on the winning effective line 22 (BB is not awarded).

  In the present invention, a stop button (a combination of symbols displayed when all reels are stopped) is advantageous for the player by operating the stop button at predetermined intervals in a preset order. As long as it is obtained, the detailed configuration is not limited to the above embodiment, and can be changed as appropriate.

For example, in the above-described embodiment, the example in which the rotation position of each reel is adjusted so that the set symbols are shifted by 5 frames has been described. However, the amount of shifting the set symbols (the value of the predetermined frame number) can be set freely. Also, if the set symbol of each reel is within the range that moves into the pull-in range every predetermined time,
The amount by which the set symbol is shifted may be different for each reel. That is, even if the rotation position of each reel is adjusted so that the set symbol is shifted by 5 frames between the first reel and the second reel, and the set symbol is shifted by 7 frames between the second reel and the third reel. Good. Also in this case, by operating the stop buttons in the first, second, and third order every predetermined time, it is possible to obtain an advantageous stop outcome for the player as in the above embodiment.

  Further, in the above-described embodiment, the example in which the same speed is a speed of moving 28 symbols per second has been described, but the same speed can be changed as appropriate. Furthermore, in the above-described embodiment, an explanation has been given of an example in which, when each stop button is operated in the order of the first, second, and third stop buttons, a stop outcome that is advantageous to the player is obtained. When the stop buttons are operated in this order (for example, the order of the third, second, and first stop buttons), a stop outcome that is advantageous to the player may be obtained.

  In the above-described embodiment, the example in which the set symbol is “red 7” has been described. However, other symbols may be set as the set symbol. Furthermore, although the example in which the set symbols are common to all reels has been described, the set symbols may be different for each reel. Further, the set symbol may be changed according to the gaming state such as the current gaming mode.

  Furthermore, when all the reels are stopped, when the set symbols of each reel are aligned on the winning effective line, the BB has been described as an example. However, the present invention is not limited to this. Game effects when the set symbols of each reel are aligned on the winning line when all the reels are stopped (for example, a transitional role (for example, ART that shifts to an advantageous mode when a small role is won) A winning combination that shifts to a mode) wins a prize, a winning combination that ends an advantageous mode (so-called punk role) wins, or a single game ends without any winning combination winning Etc.) can be set freely.

  For example, when all the reels are stopped, when the symbol “watermelon” is aligned on the winning effective line, a prize water prize is awarded and, for example, 15 medals are paid out, and a small role watermelon that may cause a dropout is provided. . Then, in the ART mode, when this small role watermelon is won, the rotation position of each reel is adjusted so that the design “watermelon” is shifted from the first reel to the third reel by a predetermined number of frames. When the symbol “watermelon” moves into the pull-in range, the operation of all the stop buttons may be validated.

  By doing so, it is equivalent to assisting the winning of the small role watermelon, and it is possible to easily win the small role watermelon. Further, by performing such assist, it is not necessary to perform a conventional assist (such as displaying a winning combination won on the liquid crystal display), and the processing can be simplified. In this example, when the small role watermelon is missed, the pattern “blank” may be aligned on the winning line and the ART mode may be terminated.

  Further, for example, in the ART mode, there is provided a puncture combination plum that is awarded when the symbol “plum” is aligned on the winning line when all reels are stopped and the ART mode ends. Then, in the ART mode, when this punctured plum is won, the rotational position of each reel is adjusted so that the design “plum” is shifted from the first reel to the third reel by a predetermined number of frames. The operation of all stop buttons may be validated when the symbol “Plum” moves out of the pull-in range. In this example, when the symbol “Plum” is not aligned on the winning line, the symbol “Blank 2” is aligned on the winning line, and the ART mode 2 in which the winning probability of replay is higher than the above-mentioned ART mode. You may make it transfer to.

  In the above embodiment, if it is more advantageous for the player to align the set symbols on the winning pay line, the operation of the stop button is enabled when the set symbols move into the pull-in range, and the set symbols are won. In the case where it is advantageous for the player not to align on the effective line, the example of enabling the operation of the stop button when the set symbol moves out of the drawing range has been described, but the present invention is limited to this. It is not a thing. The operation of the stop button may be validated when all reels reach the same speed, regardless of whether it is advantageous for the player to align the set symbols on the winning line.

  In this case, even if the stop button is operated every predetermined time, the set symbols may or may not be aligned on the winning line depending on the operation timing of the stop button operated first. That is, if the first stop button is operated when the set symbol is within the pull-in range, the set symbol is aligned on the winning line, and if the first stop button is operated when the set symbol is not within the pull-in range The set symbols are not on the winning line.

  For this reason, when it is advantageous for the player to have the set symbols aligned on the winning line, the player operates the first stop button when the set symbols are within the pull-in range, and the set symbols are aligned on the winning line. When the first stop button is operated, such as when the first stop button is operated when the set symbol does not exist within the pull-in range, it is necessary to press the eye. However, paying attention to the operation timing of the first stop button, it is possible to obtain a stop outcome that is advantageous to the player by operating the subsequent stop buttons every predetermined time. It is easier to obtain a stop outcome that is advantageous to the player as compared to a case where it is not possible to obtain a stop outcome that is advantageous to the player unless it is stopped.

  Furthermore, in the above-described embodiment, the example in which it is determined whether or not the set symbols are aligned on the winning line is determined by the operation timing of the first stop button, but the present invention is not limited to this. . For example, even if the first stop button is operated in a state where the set symbols are within the pull-in range, if the subsequent stop buttons are operated in a predetermined order every predetermined time, the set symbols are not aligned on the winning line. In this way, the position of the set symbol to be arranged on each reel may be determined.

  Further, when the rotational position adjustment process is performed, an operation interval (predetermined time) of the stop button that can obtain a stop outcome advantageous to the player may be notified. In this case, the notification may be performed by displaying a predetermined time on the liquid crystal display, turning on the lamp every predetermined time, or outputting a notification sound from the speaker every predetermined time.

  The present invention is not limited to the reel drive type slot machine, but can be equally applied to other gaming machines such as a slot machine using a liquid crystal panel and a slot machine using a pachinko ball as a gaming medium. Moreover, you may use combining the structure demonstrated in the said embodiment and the various aspects mentioned above suitably.
