A variable display game that executes and rotates a plurality of spinning cylinders to vary a plurality of symbols displayed on the spinning cylinder (usually, the plurality of symbols are pasted on three drums). A big bonus game mode (BB game mode) that is the most advantageous game mode for the player when a specific symbol (for example, red 7 symbols) is aligned on the activated line, and the accessory continuous action device operates. ).

  Then, in this big bonus game (BB game), one set of jack games (first type special character) is immediately activated in 6 games, and the BB game mode ends when the number of acquired games exceeds 375. It is supposed to be.

  In addition, when the bar symbols are arranged on the active line as the specific symbols, the RB game (the first kind special role) is activated only once, and a maximum of 90 medals can be obtained in the six-game jack game. Thus, even if the number of balls to be played is slightly different between BB and RB, the player's greatest concern in the revolving game is to acquire a bonus game.

  By the way, as described above, in a conventional and normal pachislot machine, an internal lottery is performed and a bonus game is awarded when winning, but this bonus grant rate is the output rate set for each pachislot machine It is almost determined by the step set values (1 to 6). If the average is taken over a long span, it is basically irrelevant to the skill of the player. As a result, in order for the player to win, it depends on how to select a gaming machine having a high step set value.

A board protection device 193 is provided to lock the substrate cases 19A and 19B together and release the lock.When locking by the substrate protection device, a plurality of substrate cases can be protected together, and when releasing the lock, a plurality of substrate cases can be simultaneously locked. An application for a gaming machine has been published in which it is possible to easily and surely protect against gossip such as tampering with ROM while improving convenience of inspection and repair.

  As a second prior art (Patent Document 2), the issue is “to improve the defense function of the gaming machine 5 to the board”, “a big hit lottery random number that starts to fluctuate from an initial value at a predetermined stake, Based on the value of the jackpot lottery random number, in the gaming machine 5 provided with the jackpot determination process (S1190) for determining whether or not to provide the jackpot, it is determined from the start of the variation of the jackpot lottery random number until the random number makes one round. And a process (S414) for preventing the determination that the jackpot providing is performed by the jackpot determination process until it is determined that the random number has been made one round. " The game machine has been published.

  FIG. 5 is a drum symbol arrangement table.

  In each of the left drum 2a, the middle drum 2b, and the right drum 2c, a swirl belt having a left drum symbol, a middle drum symbol, and a right drum symbol as illustrated in FIG. It is stuck like so.

  Each swirl belt has 21 differently drawn symbols, including the big bonus symbols “Red 7” and “Blue 7”, the cross that triggers the release of the stock big bonus or regular bonus, There are cherries and watermelons that trigger lottery for mode transition from a low probability state to a high probability state, and bells and replays having the opposite function.

  Now, as shown in FIG. 4, the cylinder sensors 20a, 20b, and 20c are provided for the step motors 19a, 19b, and 19c, respectively, and an index signal is 1 from each cylinder sensor in response to one rotation of the step motor. Since the pulse returns, the main control unit 100 grasps the symbol number based on the number of the index signal and the output drive pulse signal, and considers the symbol arrangement shown in FIG. It is always possible to recognize whether it reaches the effective line of each drum.

  FIG. 6 is a block diagram showing the configuration of the drum unit 2. FIGS. 6A and 6B show the state in which the right drum 2c is controlled to be pulled in time series.

  The main control unit 100 receives the start signal of the variable display game, and when the lottery result is won and the winning combination is established, the main control unit 100 performs pulling-in control for drawing in so as to align the symbols of the winning combination on the active line. .

  For example, if the symbol “7, 7” is on the effective line diagonally to the lower right of the left drum 2a and the middle drum 2b when the big bonus combination is won internally, the pattern is within 4 frames from this effective line. When the stop button 10c is operated in a state where “7” is positioned (see FIG. 6A), the main control unit 100 forcibly aligns it on the effective line and sets “7, 7, 7”. Pull-in control is performed so that the combination is achieved (see FIG. 6B). On the other hand, even if any winning combination is established by lottery, if a predetermined symbol corresponding to the winning combination is not displayed on the active line, it is not advantageous to the player. For example, a big bonus (BB) game is not started unless it is displayed as shown in FIG. This pull-in control is performed not only on the right drum 2c but also on the symbols of the left drum 2a and the middle drum 2b.

  In the example of FIG. 6, the symbol “7” of the right drum 2 c is exactly 4 frames above, and is arranged on the effective line as a target of pull-in control. However, this pull-in control is not limited to four frames, and the number of pull-in frames can be increased / decreased by software control so as to be adapted to the design specifications or legal regulations.

  FIG. 7 is a block diagram of the configuration of the drum unit 2. FIGS. 7A and 7B show the state in which the right drum 2c is controlled to be avoided in time series.

  When the main control unit 100 receives the start signal of the variable display game, and the lottery result is lost and the combination is not established, the main control unit 100 does not align the symbols of the winning combination (bonus or small combination) on the active line. Perform avoidance control.

  For example, when the big bonus combination is not internally won and the symbols “7, 7” are aligned on the effective line diagonally to the lower right of the stopped left drum 2a and middle drum 2b (so-called reach state) When the stop button 10c is operated by a person who is "eye-pressing" and the symbol "7" is located within one frame from this effective line (referred to as "bitter pressing", see FIG. 7A). ), The main control unit 100 performs the avoidance control in which the symbol “7” is forcibly moved to the next position so that “7, 7, 7” is not aligned on the effective line (FIG. 7B). )reference). This avoidance control is performed not only for the right drum 2c but also for the symbols of the left drum 2a and the middle drum 2b.

  FIG. 8 is a configuration block diagram of the display effect device.

  The display effect device 11 includes a command receiving unit 11a, a display effect control unit 11b (including a ROM 11c and a RAM 11d), and a display panel 11e.

  FIG. 9 is a conceptual diagram of an effect pattern data table stored in the ROM 11c.

  The effect command is composed of 1-byte length mode data and 1-byte length event data, and stores an effect pattern that is the effect content.

  When the sub-control unit 160 receives control data necessary for various controls from the main control unit 100, the sub-control unit 160 transmits an appropriate effect command corresponding to the control data to the display effect device 11 side, and the command receiving unit 11a transmits the effect command. Receive and pass to the display effect control unit 11b.

  When receiving the effect command, the display effect control unit 11b reads the effect pattern corresponding to the effect command from the ROM 11c, expands the data in the RAM 11d, and transmits the data to the display panel 11e, thereby displaying the effect corresponding to the effect command on the display screen. It is configured to display. For example, when the sub-control unit 160 transmits ($ Y0 $ 00) as an effect command, the display panel 11e displays “night effect pattern 0” (second display stage mainly indicating that it is in the second state). It is like that. On the other hand, when the sub-control unit 160 transmits ($ Z0 $ 00) as an effect command, the display panel 11e displays “daytime effect pattern 0” (first display stage that mainly indicates that it is in the first state). It is like that. Therefore, the player longs for the daytime stage to be displayed during the game.

  FIG. 10 is a conceptual diagram of the winning table.

  The winning table is stored in a predetermined area of the ROM 101, and defines the relationship between the winning combination and the random number used for the symbol lottery in the low probability state and the high probability state.

  For example, in the case of the revolving game machine of the present invention, the random value takes a value of 0 to 16383 at random, and when the start lever 9 draws a symbol in accordance with the operation timing in a low probability state, the random value is If it is in the range of 0 to m1, the big bonus (BB) symbol is won. Similarly, when a symbol is drawn in a high probability state, if the random value is in the range of 0 to n1, the big bonus symbol is won, but since the relationship is m1 <n1, the higher probability state Big bonus symbols are easier to win than in the low probability state. In addition, the probability of winning a cross symbol that triggers the release of regular bonus symbols and stock bonus games (a bonus game won with a random lottery, with a maximum stock of, for example, 255) However, since m3 <n2 and m5 <n3, the bonus symbols are easier to win in the high probability state. When a bonus symbol or a cross symbol is won, flag 1 is set in the flag area of the RAM 102, and it is not cleared until the symbols are aligned on the active line. You can enter a Dracula mission (a big hit sign mode). However, even if the cross symbols are not aligned on the active line, the Dracula mission is automatically started when the predetermined number of games is exhausted.

  On the other hand, for the convenience of explanation, the probability that the cherry symbol and watermelon symbol, which are the lottery triggers for mode transition to the high probability state, and the bell symbol and replay symbol having the opposite function are won is the same for both the high probability state and the low probability state. Yes.

  Therefore, regardless of the probability state, if the random number drawn is in the range of m6 to m7, the cherry symbol is present, the watermelon symbol is in the range of m8 to m9, and the bell symbol is in the range of m10 to m11. If it is in the range of m12 to m13, the replay symbol is won, and if it is a random number other than this, the stock bonus is won or the net is lost. Note that the number of stock bonuses is managed as an 8-bit value, and a maximum of 255 pieces can be stored. In addition, when a pure loss occurs, an RB (regular bonus) is immediately released.

  Normally, the numerical values of m1 to m13 and n1 to n3 are appropriately set in consideration of legal regulations and game characteristics, but the BB winning probability is about “1/300” and the RB winning probability is “1/500”. The winning probability of the cross is about “1/100”, the winning probability of cherry and watermelon is about “1/50”, and the winning probability of bell and replay is about “1/7”.

  In addition, as the winning table, there are six winning tables 1, winning tables 2... Winning table 6 corresponding to the payout rate step values 1 to 6, and the main control unit sets the step values set by the step setting unit 150. The winning table is selected in response to the bonus game and the internal lottery of a plurality of small roles in the variable display game. Note that the expected value for winning the bonus game in the internal lottery is the winning table 1 <winning table 2 <... <Winning table 6, as described in the low probability state and the high probability state. A high setting stand is required.

  FIG. 11 is a payout table showing the relationship between the combination of symbols and the number of acquired medals in a general game.

  BB (Big Bonus) is a title when “Red 7” or “Blue 7” BB symbols are aligned on the active line, and when they are aligned, 15 medals are obtained and the corresponding flag area The flag 1 is set to, and the game enters the big bonus game (BB game: operation of the continuous action device).

  RB (Regular Bonus) is an irregular name, but it is the title when the RB symbols of “Red 7, Red 7, Cross” or “Blue 7, Blue 7, Cross” are aligned on the effective line. 15 medals are acquired, and a flag 1 is set in the corresponding flag area to enter a regular bonus game (RB game: operation of a first type special character).

  When watermelon symbols or cherry symbols are aligned on the active line, 5 or 2 medals are obtained respectively, and when in a low probability state, a promotion lottery for shifting to a high probability state is performed. It is carried out. In addition, when shifting from the low probability state to the high probability state, the screen display is switched from the night screen (second display stage) to the day screen (first display stage) on one of the watermelon or cherry symbols determined by lottery. It is done. Even when the low-probability state shifts to the high-probability state, the second display stage may be switched to the first display stage only when the screen display switching lottery is won.

  When the bell symbols are aligned on the active line, nine medals are obtained, and when in the high probability state, a relegation lottery for shifting to the low probability state is performed.

  Replay is the title when the replay symbols are aligned on the active line. Normally, no medal is acquired, flag 1 is set in the flag area, and the replay operation is performed by operating the start lever 9 of the player. To lower the flag (that is, 0). In other words, the next game can be played without inserting medals, while when in a high probability state, a demotion lottery for shifting to a low probability state is performed.

  In addition, as a result of the lottery of bell symbols or replay symbols being demoted, if the transition from the high probability state to the low probability state, one of the bell symbols or replay symbols determined in the lottery, from the day screen (first display stage) The screen display can be switched to the night screen (second display stage). Even when the high-probability state shifts to the low-probability state, the first display stage may be switched to the second display stage only when the lottery for screen display switching is won.

  This figure does not include a cross symbol, but it has only a function that serves as a lottery for the stock bonus, and the number of medals earned is zero even if the cross symbols are aligned.

  FIG. 19 is a schematic front view of the inside of the rotary type gaming machine according to the present invention.

  The drum section 2 is disposed at the center of the spinning cylinder gaming machine body 1 and the medal payout device 18 (medal hopper 18) is disposed below the drum section 2.

  Reference numeral 170 denotes a power supply unit. When the power switch 170c is turned on, power is supplied to each circuit block, and after the initial check and initial setting, a variable display game can be played.

  Reference numeral 170a denotes a setting key switch, which is used when setting the stage of the payout rate and checking the stage.

  Reference numeral 170b denotes an error release switch, which is used when setting the stage of the payout rate or when canceling the game stop due to an error.

  4c is a medal payout number display LED which displays a step setting value of the payout rate. The value is incremented by 1 every time the error release switch 170b is pressed, and returns to “1” after “6” is displayed. , Turnaround display.

_{Reference numeral 210 denotes a main board mounted in the electronic circuit block, and the main control unit 100 is disposed on the main board.}

_{Reference numeral 220 denotes a sub-board mounted in the electronic circuit block, and the sub-control unit 160 is arranged on this sub-board.}

  Next, the operation of the gaming machine according to the present invention configured as described above will be described in detail with reference to flowcharts and the like.

  First, in a state in which the spinning machine is shipped from the factory, the warning mode is set to “ON” as a default, and the stage setting value is set to “1”.

  The game hall side supplies power to each circuit block by opening the front door of the swivel type gaming machine main body 1 and turning on the power switch 170c before allowing the player to play. Checks and initial settings (for example, step set value “1”) are executed, and the sub-control unit 160 sets the warning mode to “ON” so that a variable display game can be played when the front door is closed. Become. Even if the game hall side opens the front door again and operates the input SW unit 22 (operation for simultaneously pressing the initialization switch and the volume switch) in this game-ready state, the sub-control unit 160 does not change the main control unit 100. Since the control data of the stage setting mode of the payout rate is not received from the “warning mode”, the warning mode is not changed from the “on state” to another state (“off state” or “timer state”). Therefore, there is a specific effect that Goto and the like cannot easily change the warning mode.

  It is assumed that the game hall side is changing the setting of the payout rate for the grand opening, the opening of a new store or an event in this setting state.

  FIG. 12 is a flowchart showing main operation processing of the gaming machine according to the present invention.

  An employee of the gaming hall opens the front door of the swing type gaming machine body 1 to turn off the power switch 170c, inserts the setting change key into the setting key switch 170a and turns it to the right to turn it on (FIG. 19). When the power switch 170c is turned on again, power is supplied to each circuit block, and after initial settings and initial checks are performed, the main controller 100 sets in step 200. It is determined whether the key switch 170a is in an ON state.

  If the main control unit 100 is in the ON state, the main control unit 100 calls the setting change subroutine in step 210 and then proceeds to step 220. If not, the main control unit 100 proceeds to step 220 as it is.

  FIG. 20 is a flowchart showing a setting change subroutine.

  When the main control unit 100 calls the setting change subroutine, in step 500, the main control unit 100 transmits control data indicating the start of the step setting mode to the sub control unit 160, and proceeds to step 510, where the current step set value “ “1” is read and “1” is displayed on the medal payout number display LED 4c (see FIG. 19). The warning operation will be described in detail with reference to FIG.

  In step 520, the main control unit 100 accepts a step setting change operation by the medal payout number display LED 4c, displays the changed step setting on the medal payout number display LED 4c (see FIG. 19), and in step 530, the start lever 9 It is determined whether or not is operated.

  If the start lever 9 is not operated in step 530, the main control unit 100 proceeds to step 520 and repeats the step setting change operation. On the other hand, if the start lever 9 is operated, the main control unit 100 proceeds to step 540.

  In step 540, the main control unit 100 writes the selected stage setting value (for example, “6” which is the highest value), clears other data stored in the RAM, and proceeds to step 550.

  In step 550, the main control unit 100 determines whether or not the step setting change operation has been performed again. If the operation has been performed, the main control unit 100 proceeds to step 520 and repeats the step setting change operation, while the operation is performed. If not, the process proceeds to step 560.

  In step 560, the main control unit 100 determines whether or not the setting key switch 170a is in an OFF state (see the enlarged view of the setting key switch in FIG. 19). On the other hand, if it is in the OFF state, the process proceeds to step 570.

  In step 570, the main control unit 100 transmits control data indicating the end of the step setting mode to the sub control unit 160, and ends this subroutine.

  FIG. 21 is a flowchart showing a warning processing subroutine executed in the sub-block.

  When receiving the control data indicating the start of the step setting mode from the main control unit 100, the sub-control unit 160 determines in step 600 whether or not the warning generation function is in the off state. The process shifts to cancel (stops) the warning operation, but if not in the OFF state, the process proceeds to step 610.

  In step 610, the sub-control unit 160 determines whether or not the warning generation function is in the timer state. If it is in the timer state, the sub-control unit 160 proceeds to step 620, but not in the timer state (that is, in the on state). Proceeding to step 640, a warning is generated. For example, the sub-control unit 160 repeatedly generates loud sounds and words (“settings are being changed”) from the speaker unit 12 as the warning, and performs a brilliant light effect on the gaming state display LED unit 13. Further, the drum unit 2 may be rotated to vibrate.

  In step 620 (timer mode), the sub-control unit 160 determines whether or not the time measured by the time measuring means is within a predetermined time stored in the RAM (for example, from 10 am to 11 pm in the business hours). If it is within the predetermined time, the process proceeds to step 640 to generate a warning, while if it is not within the predetermined time, the process proceeds to step 630 to cancel (stop) the warning operation.

  After processing either step 630 or step 640, the sub-control unit 160 proceeds to step 650 and accepts a warning mode change operation. For example, since the current warning mode is in the on state, when the input SW unit 22 is operated, it is turned off, and when the input SW unit 22 is operated next, the timer state is entered, and finally it is turned on. Further, since the warning mode is displayed on the display effect device 11, the hall side can be confirmed by looking at the display. As an operation of the input SW unit 22, when both the initialization switch and the volume switch are pressed at the same time and pressed for about 10 seconds, the change input is accepted and the warning mode is changed. The reason why two switches are provided for changing the warning mode and the operation specification is to press and hold simultaneously is to prevent Goto and the like from easily changing the warning mode.

  For setting the predetermined time used in the timer mode, in the stage setting mode, for example, a start time and an end time of the predetermined time are input by using a separately provided time zone setting key. However, the start time or the end time may be input with the volume switch and may be determined and input with the initialization switch, without needing to be provided separately.

  Next, the sub-control unit 160 proceeds to step 660 and determines whether or not control data indicating the end of the stage setting mode has been received from the main control unit 100. If not received, the process proceeds to step 600. If the same operation is repeated, the process proceeds to step 670, where the warning operation is canceled and the process ends.

  Returning to FIG. 12, the description of the main operation process of the gaming machine according to the present invention is continued.

  As described above, the game hall side inputs the stage setting value “6” of the payout rate before making the player play, hits the start lever 9 once to confirm the setting value, and turns off the setting key switch 170a. Then, the main control unit 100 sets the set value to “6” in step 220, clears all data and flags, and executes a hardware abnormality check (initial setting). In addition, since the software of the stock bonus data is usually set so as not to be cleared, the stock bonus is not generated.

  In the same step, the main control unit 100 draws and determines the number of games (the number of released games) and the probability state until the bonus game is released according to the step set value. For example, the main control unit 100 performs random lottery for the number of released games to any number from 1 to 1300 games and for the probability state to be either high or low, depending on the stage setting value (values 1 to 6). The probability of being advantageous or unfavorable for the player is distributed, and here, it is assumed that the number of released games has become a low probability state with 500 games as a result of the lottery.

  In addition, the main control unit 100, in the same step, selects a small role for switching the display stage of the display effect device 11 from among cherry and watermelon, which are small roles used for the promotion lottery from the low probability state to the high probability state. A lottery for (first lottery small role) is executed (promotional small role function sorting lottery). In this lottery, it is assumed that the probability that Cherry becomes the first lottery role is 90%, and that Cherry becomes the first lottery role and watermelon becomes the second lottery role.

  In the same step, the main control unit 100, in the same step, out of the bells and replays, which are the small roles used for the relegation lottery from the high probability state to the low probability state, changes the display stage of the display effect device 11 (first (3 lottery small roles) is executed (relegation small role function distribution lottery). In this lottery, it is assumed that there is a 90% probability that Bell will be the third lottery role, and that Bell is the third lottery role and the replay is the fourth lottery role. However, these small role function sorting lotteries may be performed between the end of one variation display game and the start of the next variation display game. The effect is that the first lottery and second lottery, and the third lottery and fourth lottery are not fixed, so that the player can demonstrate imagination and reasoning about the internal state accordingly. It is possible to improve the game performance of the swing type gaming machine.

  Then, when the main control unit 100 outputs control data to the sub-control unit 160 in order to set display of the initial screen in the same step, as described above, since the big hit probability is in a low probability state, for example, the sub-control When the unit 160 transmits ($ Y0 $ 01) as an effect command, the display effect device 11 is a second display stage mainly showing that the display panel 11e is in the second state, and the full moon in the night sky, Dracula Castle “Night effect pattern 1” composed of the cemetery screen is displayed (see FIG. 13A, “Night normal screen”).

  Next, in step 221, the main control unit 100 checks whether or not the player has inserted the required number of game medals by the medal detection sensor 130 or the bet button sensor 140. On the other hand, if not, the process returns to step 221 and waits until there is an input operation (that is, loops step 221).

  Next, in step 222, the main control unit 100 determines whether or not to output control data indicating that a game medal has been inserted, and outputs control data to the sub-control unit 160 only once per game. After that, the process proceeds to step 230.

  Upon receiving this control data, the sub-control unit 160 determines in step 223 whether or not to display the direction in which the start lever 9 should be operated, and if so, after calling the direction display processing subroutine. On the other hand, the process proceeds to step 230. If not displayed, the process proceeds to step 230.

  For example, in this step 223, the sub-control unit 160 performs a lottery with a winning probability of about 5% to 10%, and determines that a display effect will be performed if it is won. In addition, the lottery is performed with a difference in the winning probability according to the probability state so that the winning probability is about 1% to 2% in the low probability state and the winning probability is about 25% to 50% in the high probability state. (In other words, if a lottery is performed so that the display effect is more likely to be won in a higher probability state than in a low probability state), it is in a high probability state or in a low probability state depending on the frequency of the direction display effect. The player can be very enthusiastic about the subsequent variable display game.

  FIG. 23 is a schematic diagram of an effect screen displayed by the display effect device 11 and shows a state in which the direction display processing subroutine is executed and the direction display effect is performed.

  FIG. 23 (A) shows a case where only a left arrow is additionally displayed on the “daytime normal screen” shown in FIG. 13 (B), indicating that the player should operate the start lever 9 to the left. It appeals to. It should be noted that not only the left direction but also right and vertical arrows are displayed as appropriate.

  Also, when the lottery is already over and the bonus game is won, as shown in FIGS. 23 (B) and 23 (C), a direction display effect (for example, direction display different from the normal arrow) is shown. If the characters “BONUS” are displayed on the arrows, or if the premier character Princess Sarah or the like performs an operation direction), the player can be excited and moved.

  Next, in step 230, the main control unit 100 confirms whether or not the player has operated the start lever to start the variable display game, and if started, the process proceeds to step 240 while starting. If not, the process returns to step 221 and waits until there is a start operation (that is, loops from step 221 to step 230).

  Next, the main control unit 100 executes main processing of the variable display game in Step 240. For example, when the player operates the start lever 9 after inserting a predetermined number of medals, a start signal is output from the start SW sensor 110, so the main control unit 100 performs random number lottery in accordance with the reception timing of the start signal. Then, the random number lottery value is compared with the winning table in the low probability state to determine whether or not a prize has been won (see the description of FIG. 10).

  Then, the main control unit 100 rotates the drum unit 2 all at once, and a plurality of symbols displayed on the left drum 2a, the middle drum 2b, and the right drum 2c (in this embodiment, each drum has 21 The change display game is changed, and a lottery result command is transmitted to the sub-control unit 160.

  Based on the lottery result command and the up / down / left / right direction signal output from the operation direction sensor 111 when the start lever 9 is operated, the sub-control unit 160 causes the display effect device 11 to respond to the random number lottery result and the operation direction. The notice is displayed and the player is alerted.

  For example, when the big bonus or regular bonus is won in the state where the direction display effect is not performed, the Dracula mission in the jackpot sign mode is started and the gate of the Dracula Castle is enlarged and displayed (see FIG. 14A). ) Open the closed door after entering the inside of Dracula Castle (see FIGS. 14B and 14C), and display the luxurious temple in Dracula Castle (see FIG. 14D). Also, as other premier announcement displays, the character's butler appears digging out the letters “BONUS” and “Princess Sarah” from the grave hole in the center of the screen, with the cry of “Ollya” and the sound effect of “Tiroro Loroan” (See FIGS. 15A and 15B).

  In addition, when performing notification display of cherry or watermelon, or bell or replay, which is called a rare small role, red, green, or yellow or silver bats are displayed as “bass, bass, While a sound effect “bass” is displayed, a state of flying from the Dracula Castle displayed in the center of the screen is displayed (see FIG. 16), and in the case of a loss, no special notification is displayed. However, even in the case of a loss, in order to improve the gameability by giving the player a sense of tension, a black bat that means a loss is skipped on the screen as needed, as with bonuses and rare small role announcements. Or a butler may dig a skull from a grave hole and appear.

  On the other hand, when the sub-control unit 160 receives the lottery result command and the direction signal in a state where the player has performed the direction display effect before performing the start operation of the variable display game, a plurality of items related to the result of the internal lottery are received. The video effect to be displayed is selected from the video effects according to the direction indicated by the direction signal and displayed on the display effect device 11.

  For example, the sub-control unit 160 displays the direction to be input on the display device when the player operates the start lever 9 in the left direction in the display state of FIG. If the direction detected by the detection means coincides with the direction displayed on the display device), the display screen is scrolled in the detected direction, and based on the lottery result command, cherry or watermelon or bell or replay of the winning small part Display the symbol and notify the player. When the bonus game is won by the lottery result command, the bonus game is played without scrolling the display screen in a direction different from the detected direction (that is, the direction other than the left) or without scrolling the display screen. A video effect indicating the winning is displayed on the display effect device 11.

  Conversely, in the display state of FIG. 23A, when the player operates the start lever 9 in a direction other than the left direction (that is, the direction to be input is displayed on the display device and detected by the input direction detecting means). If the displayed direction does not match the direction displayed on the display device), the player can display the winning small role cherry, watermelon, bell or replay symbol based on the lottery result command without scrolling the display screen. To announce. When the bonus game is won by the lottery result command, the display screen is scrolled in the detected direction or the direction to be input (that is, the left direction), and a video effect indicating that the bonus game is won is displayed. 11 is displayed.

  Further, the sub-control unit 160 displays the direction to be input on the display device when the player operates the start lever 9 in the left direction in the display state of FIG. 23B or FIG. 23C. And when the direction detected by the input direction detecting means coincides with the direction displayed on the display device), the display screen is scrolled in the detected direction to display a video effect indicating that the bonus game is won. It is displayed on the device 11 (see FIG. 15A or FIG. 15B). On the other hand, if the player operates the start lever 9 in the other direction even though the bonus game is won and the direction to be input is displayed on the display device, the bonus game is invalidated. It may be. By doing so, it is possible to give the player a sense of tension. Alternatively, the bonus game winning invalidity may be displayed once, and then the bonus game may be won again.

  Note that, as shown in FIGS. 24A to 24C, the direction display effects may be displayed simultaneously by selecting a plurality of directions from four directions (up, down, left, and right) instead of only one direction (eg, arrows). Means two to four).

  In addition, as shown in FIGS. 25A to 25C, the lottery results may be displayed on a plurality of arrows to allow the player to select a desired result.

  In this case, “BONUS” is operated when the left direction is operated, “NG” is operated when the right direction is operated, “Question Mark” is operated when the upward direction is operated, and “PRESENT” is operated when the downward direction is operated. When operated, the lottery result means “bonus”, “out of”, “unknown” and “something hits (for example, a high probability state)”.

  Returning to FIG. 12, the description will be continued.

  In step 240, the main control unit 100 aligns the symbols of the role on the active line when the winning combination is established as a result of the internal lottery as described with reference to FIGS. 6 and 7. Pull-in control, or conversely, if the combination is lost and the combination is not established, avoidance control is performed to prevent the winning combination (bonus or small combination) from being arranged on the active line.

  The main control unit 100 wins the game if the same symbol is displayed on the window 3 along the active line in each variation display game of the general game, and the game medal is paid out according to the payout table shown in FIG. The payout is made from the apparatus (generally called “medal hopper”), discharged from the medal payout outlet 16, and the process proceeds to step 250. In the big bonus game (BB game), one set of RB games (Jack game or first-class special object) is immediately repeated in 6 games, and when the number of acquired games exceeds 375, the BB game mode Exit. In the regular bonus game (RB game), six jack games are executed, and the RB game mode is terminated.

  Next, the main control unit 100 determines whether or not a lottery winning combination has been established as a result of the internal lottery in step 250. If it is established, the process proceeds to step 260. If not, the process proceeds to step 221. Return and repeat the same process.

  FIG. 17 is a flow chart showing a promotion display stage processing subroutine of the swivel type gaming machine according to the present invention.

  Upon entering this subroutine, the main control unit 100, in step 300, has a low probability of jackpot and a lottery small role that has been established becomes a chance for a lottery to shift to a high probability state. If it is not a low-probability and promoted lottery small combination, the process is terminated and the process exits from this subroutine.

  When the main control unit 100 proceeds to step 310, the main control unit 100 performs a mode transition lottery from the low probability state to the high probability state, and if it is lost, the main control unit 100 ends and exits this subroutine (that is, maintains the low probability state). If it is a win, the mode shifts to the high probability state at step 320, and then shifts to step 330.

  When the main control unit 100 proceeds to step 330, the main control unit 100 determines whether or not the promoted lottery role is the first lottery role (in this case, cherry) for switching the display stage of the display device. If not, the process ends and exits from this subroutine.

  When the main control unit 100 proceeds to step 340, the main control unit 100 performs screen display switching lottery from the night stage to the day stage (that is, from the second display stage to the first display stage). If you win the game (that is, keep the night stage), if you win, the clock will be displayed in full screen in step 350, and the clock hands will be displayed at high speed with the sound effect “Khan, Khan, Khan, Wow Wow”. Then, the screen is switched to the daytime stage and the process is terminated (see “normal daytime screen” in FIG. 13B). In this subroutine, step 340 for performing screen display switching lottery is provided, but if step 340 is eliminated and the process proceeds to step 350 without executing display switching lottery, if the cherry is the first lottery small role cherry. All screen displays may be switched.

  Finally, when the main control unit 100 exits the promotion display stage processing subroutine, the main control unit 100 proceeds to step 270 in FIG. 12 and calls the demotion display stage processing subroutine.

  FIG. 18 is a flowchart showing a demotion display stage processing subroutine of the swivel type gaming machine according to the present invention.

  When the main control unit 100 enters this subroutine, the relegation lottery (bell or bell) that triggers the lottery for the mode change to the low probability state when the lottery winning combination with a high probability of winning in step 400 is established in step 400. If it is not a high-probability and demoted lottery small part, the process is terminated and the subroutine is exited. On the other hand, if it is a demoted lottery small part, step 410 is entered.

  When the main control unit 100 proceeds to step 410, the main control unit 100 performs a mode transition lottery from the high probability state to the low probability state, and if it is lost, the main control unit 100 ends and exits this subroutine (that is, maintains the high probability state). If it is a win, the mode shifts to the low probability state at step 420, and then shifts to step 430.

  When the main control unit 100 proceeds to step 430, the main control unit 100 determines whether or not the demoted lottery role is a third lottery role (in this case, a bell) for switching the display stage of the display device. If not, the process ends and exits from this subroutine.

  When the main control unit 100 proceeds to step 440, the main control unit 100 performs screen display switching lottery from the day stage to the night stage (that is, from the first display stage to the second display stage). If the player wins (ie, keeps the daytime stage), the clock will be displayed in full screen at step 450, and the clock hands will sound at high speed with the sound effect “Khan, Khan, Khan, Wow Wow”. After rotating with, switch the screen to the night stage and finish. In this subroutine, step 440 for performing screen display switching lottery is provided, but if step 440 is eliminated and the process proceeds to step 450 without executing the display switching lottery, the bell is the third lottery small role. All screen displays may be switched.
