Description

  The present invention relates to a slot machine.

  Conventionally, in a slot machine that can shift from a normal state to a special state such as an AT, a slot machine that shifts to a special state via a chance state is exemplified in Patent Document 1 below, for example. In this patent document 1, when a specific winning combination is won, a special lottery is performed to give a privilege if it is a normal state, but if it is a special state, a privilege is given regardless of the lottery. It has been proposed to suppress the decline.

  Now, due to recent amendments to the internal rules of game machine manufacturers, etc., it is necessary to create a normal section and an advantageous section, and to make it a special state, it is necessary to make it an advantageous section. However, there is a need for a specification that does not allow a shift without winning a lottery like a so-called ceiling.

JP 2017-70642 A

  However, when adopting the specifications of the above conventional slot machine, it is assumed that a chance state is provided in an advantageous section and a transition from the chance state to a special state is assumed, but in a normal section, a transition is made to a special state by a so-called ceiling. However, it is difficult to keep the game interesting, because the lowering of gaming motivation is promoted.

  In view of the circumstances described above, an object of the present invention is to provide a slot machine capable of suppressing a decrease in gaming motivation in a normal section.

  In the slot machine of the present invention, the gaming state can be shifted between the first gaming state and the second gaming state. Then, a special state in which the game value grant rate is improved does not occur in the first game state, but a special state occurs on the condition that the game state is the second game state or a transition to the second game state. That is, the second gaming state in the slot machine of the present invention corresponds to an advantageous section in which a special state can be generated. Further, the second gaming state is divided into a first mode and a second mode in which the occurrence condition of the special state is more advantageous for the player than the first mode.

  In the first gaming state of the slot machine of the present invention, a special state does not occur, and even if a predetermined number of games are executed as in the so-called ceiling, it cannot be shifted to the second gaming state. Therefore, the first gaming state in this slot machine is a gaming state corresponding to a normal section in which the game motivation may be reduced.

  In the first gaming state of the slot machine of the present invention, it is possible to shift to the second mode (second gaming state) in which the special condition occurrence condition is advantageous for the player. On the other hand, in the second gaming state, in the first mode in which the condition for generating the special state is disadvantageous compared to the second mode, the transition to the second mode advantageous to the player is impossible, or the second gaming state is second than the first gaming state. Transition to mode is difficult.

  Therefore, the player of the slot machine of the present invention can regard the first gaming state as a chance state for the second mode. Therefore, according to this slot machine, it is possible to suppress a decrease in the player's gaming motivation during the occurrence of the first gaming state.

The embodiment of the present invention will be specifically described with reference to the following examples.
(Example)
This example relates to a slot machine 1 in which the gaming state other than the bonus state is roughly divided into an advantageous state in which an AT (an example of a special state) can be generated and a normal state in which an AT cannot be generated. The contents will be described with reference to FIGS.

  First, the external configuration of the slot machine 1 of this example will be described with reference to FIG. The front surface portion of the slot machine 1 is formed by a front frame body 10 in which a substantially rectangular symbol display window 11 is disposed substantially at the center. The front frame 10 is configured by arranging a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 on the upper side of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed below the symbol display window 11.

On the operation panel 13, a start lever 62 for starting the symbol variation of the reel 21, a stop button 61 for stopping the symbol variation, and the like are arranged.

  The symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each of the symbol display areas 110L, C, and R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display regions for nine symbols arranged in a two-dimensional matrix composed of three rows and three columns are formed. The symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. In the symbol display area in which nine symbols 20 are arranged in a two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of winning symbols to be awarded are set. As shown in FIG. 2, the winning line in this example is composed of five lines including upper, middle, and lower stages, three horizontal winning lines 211 to 213, and diagonal winning lines 214 and 215.

  On the back side of each symbol display area 110L, C, R, reels 21L, C, R constituting the symbol variation display unit 2 are respectively arranged. The reels 21L, C, and R are rotary reels in which 21 symbols 20 are arranged at a substantially constant interval on a cylindrical outer peripheral surface (see FIG. 3). Note that the reel 21 may be an image-type reel that displays symbols on a liquid crystal display in a variable manner, instead of the rotary reel of this example.

  The MAXBET button 64 is an operation button for betting a prescribed number of credited medals on the game as shown in FIG. In a non-bonus state in which a three-game betting game with a prescribed number of three is performed, three medals are bet according to the operation of the MAXBET button 64. In a bonus state in which a two-bet game with a prescribed number of two is performed, two medals are bet according to the operation of the MAXBET button 64. However, if the remaining credits are less than the specified number, all the remaining credits are bet.

The start lever 62 is an operation lever that is operated by the player to start the game. When the operation of the start lever 62 is detected in a state where a prescribed number of medals are bet, the game is started and the rotation of the reels 21 is started all at once.

The liquid crystal display unit 53 including a liquid crystal display can display various effect screens for effecting a game, a display screen for displaying game data, and the like. In particular, the liquid crystal display unit 53 of this example provides various notifications such as navigation notification during AT (AT notification), which is a special state in which a player is notified of winnings, and an effect notification that raises the player's expectation. Implement the function to execute. In particular, the liquid crystal display unit 53 of the slot machine 1 of the present example has a function as a notification unit that notifies that it is a chance zone that can be shifted to an advantageous state.

Next, the role of the slot machine 1 of this example will be described.
In the slot machine 1, as shown in FIG. 4, a replay combination is set in addition to a plurality of types of small combinations such as a bonus combination (BB combination, RB combination) and 15-sheet combination. In FIG. 4, the name of each combination is shown in the left column, the winning symbol which is a combination of symbols 20 corresponding to each symbol is shown in the middle column, and the profit such as payout given to the player according to the winning is shown in the right column. It is.

  There are four types of small combinations: 15 combination, 2 combination, 1 combination A, and 1 combination B. Among these, the one-sheet combination A and the two-sheet combination are small combinations related to the advantageous state lottery for shifting from the normal state to the advantageous state. For a single winning combination A, a single internal winning under normal conditions corresponds to winning in the advantageous lottery. For the two-piece combination, simultaneous winning with a bonus combination (BB combination or RB combination) corresponds to winning in the advantageous state lottery.

  Next, the electrical configuration of the slot machine 1 of this example will be described with reference to FIG. For the control unit 3 that controls the overall operation of the slot machine 1, in addition to the configuration described above, the inserted medal detection unit 63 that detects a medal inserted directly through the medal insertion slot 630 (FIG. 1), the reel 21. In addition, the reel driving unit 22 constituting the symbol variation display means, the reference position detecting unit 66 for detecting the rotational position of the reel 21, the medal paying unit 54 for paying out medals, the payout number display unit 551 (see FIG. 1) and the number of credits. Various display units 55 including a display unit 552, a set value operation unit 68 for setting a set value representing the player's advantage, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 outputs an insert signal every time a medal inserted from the medal insertion slot 630 is detected. In the slot machine 1, when a predetermined number of medals are inserted by direct insertion of medals or operation of the MAXBET button 64, the start lever 62 is set to an effective state so that a new game can be started. Become.

The reel drive unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and rotationally drives the reel 21 by the rotational driving force of the stepping motor.
The reference position detection unit 66 is a detection unit that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.
The set value operation unit 68 is an operation unit for changing set values of 6 stages having different internal winning probabilities for bonus combinations and small combinations using the setting key 680.

  As shown in FIG. 5, the control unit 3 includes a CPU 31, a ROM 33 / RAM 34 as memory means, an I / O unit 32 as an input / output interface, and a random number extraction unit 35 for extracting random numbers for internal winning combination lottery. A random number generator 350 for generating random numbers. The random number extraction unit 35 extracts a random number for internal winning combination lottery from random numbers (0 to 65535) generated by the random number generation unit 350.

  Although not shown, the ROM 33 stores an internal winning combination lottery table, a reel control table, an AT lottery table, a first distribution lottery table, a second distribution lottery table, an extra lottery table, and the like. In each of these lottery tables, a winning random number for collating the random numbers for the internal winning combination lottery is defined. Therefore, the lottery can be executed by comparing the random numbers for the internal winning combination lottery with each lottery table.

The reel control table is a control table used for stop control of the reel 21. In the reel control table, a stopable position is defined on the winning line.
The internal winning combination lottery table is a lottery table used for lottery of the internal winning combination. In the internal winning combination lottery table, among the 0 to 65535 internal winning combination lottery random numbers, the winning random number of each combination is defined. As the internal winning combination lottery table, there are a table for a bonus state and a table for a non-bonus state. The number of winning random numbers for winning each winning combination or winning combination is different for each of the six set values 1-6. For example, when the setting value 1 is disadvantageous to the player, the number of winning random numbers corresponding to each combination or combination of combinations is set as shown in FIG.

The AT lottery table is a lottery table for AT lottery for determining whether or not to generate an AT under the advantageous state (first advantageous state).
The first distribution lottery table is used for the first distribution lottery for determining the number of continuing games and the type of advantageous state to be transferred (first advantageous state, second advantageous state) when shifting from the normal state to the advantageous state. It is a lottery table.
The second sorting lottery table is a lottery table for determining the number of AT continuing games at the start of the AT.
The extra lottery table is a lottery table for extra lottery for determining the number of extra games to be added to the number of AT continuous games.

As shown in FIG. 5, the control unit 3 executes the software program read from the ROM 33 by the CPU 31 to realize the following functions as each means.
(1) Game means: means for allowing a game to be executed by consuming medals as game value. In the bonus state, two medals are set as the gaming value consumed for executing the game, and in the non-bonus state, three medals are set as the gaming value.

(2) Internal winning combination lottery means: means for determining an internal winning combination by internal lottery. The internal winning combination lottery means determines the internal winning combination by collating the random numbers for internal winning combination lottery against the winning random numbers of each combination specified in the internal winning combination lottery table, and determines the internal winning combination corresponding to the internal winning combination The winning flag is established.
(3) Flag control means: means for controlling an internal winning flag corresponding to the internal winning combination determined by the internal winning combination lottery means. The flag control means sets the internal winning flag of each combination other than the bonus combination to an off state (zero) until the next game is started regardless of whether or not the internal winning flag is won in the first game. Reset. Therefore, if each combination other than the bonus combination is not won in the internal winning game, all will be missed. On the other hand, regarding the bonus combination flag which is an internal winning flag of the bonus combination, the established state of the internal winning flag is sequentially carried over to the next game until winning, and is reset to the off state according to winning.

(4) Display control means: means for starting the symbol fluctuation of the reel 21 in accordance with the operation of the start lever 62 and stopping the symbol fluctuation of the reel 21 in accordance with the operation of the stop button 62. The display control means inputs a control pulse to a stepping motor (not shown) constituting the reel driving unit 22 and rotates the stepping motor by one step for each pulse, thereby changing the symbol displayed on the reel 21.
(5) Winning determination means: means for determining the presence / absence and type of a winning combination according to the combination of symbols 20 that have been stopped. The winning determination means determines the winning combination according to the combination of symbols 20 stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means obtains the type of the symbol 20 stopped on the winning lines 211 to 215 by taking in the number of steps of each corresponding stepping motor (reel driving unit 22) after each reel 21L, C, R stops. Then, it is determined whether or not a winning combination is established for the combination of symbols 20.

(6) Game value giving means: means for giving a medal (game value) when a prize is won by executing a game. The game value giving means gives the number of medals corresponding to the winning combination determined by the winning determination means (see FIG. 4). For example, when 15 winning combinations win, a benefit of paying out 15 medals is given.

(7) State transition means: The game state can be shifted between the normal state (first game state) and the advantageous state (second game state), and it is advantageous to execute a predetermined number of games in the normal state. Means for shifting to the advantageous state on condition that the advantageous state lottery (predetermined transition lottery) is won without shifting to the state. In the slot machine 1 of this example, the internal lottery for determining the internal winning combination also serves as the advantageous state lottery. The internal winning of the single winning combination A and the simultaneous winning of the bonus winning combination and the double winning combination correspond to the winning of the advantageous state lottery.
(8) First distribution lottery means: When the player shifts to the advantageous state in accordance with the internal winning of the single role A in the normal state (winning of the advantageous state lottery), the number of advantageous continued games (the number of state continuing games) .) And means for determining the kind of advantageous state by the first sorting lottery.
(9) AT lottery means: means for executing an AT lottery for determining whether or not to generate an AT under the advantageous state (only the first advantageous state in this example).

(10) Special state generating means: AT (special state) that improves the grant rate of medals (game value) is not generated in the normal state (first game state) but is in an advantageous state (second game state), Alternatively, means for generating on condition that a transition to an advantageous state occurs.

(11) Second distribution lottery means: means for determining the number of AT continuing games (referred to as the number of AT continuing games) by the second distribution lottery at the start of the AT. In the second allocation lottery for the AT under the first advantageous state (first AT) and the second allocation lottery for the AT under the second advantageous state (second AT), the number of AT continuing games is set. And the distribution ratio is different (described later).
(12) Extra lottery means: means for executing an extra lottery for determining the extra game number to be added to the AT continuing game number.

(13) Bonus state generating means: means for generating a bonus state in response to winning of a bonus combination (BB combination, RB combination). As the bonus state, there are a BB state in which the trigger combination is the BB combination and ends when the payout exceeds 315 sheets, and an RB state in which the trigger role is the RB combination and ends in response to the payout exceeding 105 sheets.

Next, (A) basic operation processing and (B) gaming state transition of the slot machine 1 configured as described above will be described.
(A) Basic Operation Process The game of the slot machine 1 is executed by operating the start lever 62 in a state where a specified number of medals are inserted and a bet is made (bet state). A random number for internal winning combination lottery is extracted in accordance with the execution of the game, and an internal lottery is executed by collating with an internal winning table corresponding to the gaming state. All the reels 21 start rotating together with the internal lottery, thereby starting symbol variation.

  During symbol variation on each reel 21, the number of control pulses input to the reel drive unit 22, that is, the number of steps rotated by the stepping motor is counted. This number of steps is reset to zero each time the reference position piece attached to each reel 21 is detected. Using this number of steps, the control unit 3 uses the number of steps as a winning line for a symbol 20 within a predetermined pull-in range (in this example, a range for four symbols) defined by rules (rules for game machine certification, type verification, etc.). The so-called pull-in control is executed, which is stopped upward. The control unit 3 checks the number of steps at the time of operating the stop button 61 against the reel control table in which the stop position on the winning line is defined, and depending on the presence / absence of the established internal winning flag and the type of flag The stop position is determined and the symbol variation is stopped.

  The slot machine 1 can generate an AT (an AT state that is a special state) in which a navigation notification for winning an internal winning combination is performed. In the AT by the slot machine 1 of this example, when the 15 role combination which is the AT combination is won simultaneously with the 1 role combination B, the push order of the stop buttons 61L, C, R is notified by navigation. If the stop buttons 61L, C, and R are operated as in the navigation notification, a 15-piece combination can be won. If the operation is not performed in accordance with the navigation notification, the symbol of the single combination B becomes the control target of the above-described pull-in control. If the single winning combination B is included in the drawing range, the single winning combination is drawn and stopped, and the 15 winning combination cannot be won.

  The slot machine 1 can generate a bonus state in addition to the special state AT. In the slot machine 1, the winning rate and the like are adjusted by varying the probability of occurrence of a bonus state and the internal winning probability of a small role according to six stages of setting values (gaming machine setting values and modes). In the slot machine 1, the payout rate for each set value is adjusted by providing a difference in the single internal winning probability of the BB combination that is not related to the advantageous state. Instead of or in addition to this, the occurrence condition of AT and the like may be different depending on the set value.

  The slot machine 1 is an example of a general slot machine of a so-called AT machine, and may be a gaming machine having any specifications. The slot machine 1 can specify a safe which is game information indicating the magnitude of game value given to a player according to a game, and the game information indicating the magnitude of game value consumed according to the game. A game signal, a game signal that can specify a bonus or AT, and the like can be output.

(B) Transition of gaming state The gaming state in the slot machine 1 is roughly divided into an advantageous state in which an AT can be generated and a normal state in which an AT cannot be generated. Further, the advantageous state is roughly divided into two, a first advantageous state (first mode) and a second advantageous state (second mode), and the second advantageous state is more than the first advantageous state. The occurrence condition of AT (special state) is advantageous for the player. It should be noted that the transition to the first advantageous state and the second advantageous state can be made only from the normal state, and no state transition occurs between the first advantageous state and the second advantageous state.

  A transition from the advantageous state to the normal state (first gaming state) occurs when an end condition (to be described later) that can be established during the advantageous state (second gaming state) is satisfied. The average number of continued games (continuation period) in the advantageous state is longer in the second advantageous state than in the first advantageous state.

  When a bonus combination and two-sheet combination are won at the same time, or an internal winning of one-piece combination A, that is, an advantageous state lottery is generated in a game under the normal state, an advantageous state in which an AT can be generated from a normal state where an AT cannot be generated The gaming state transitions to. In the game of the slot machine 1 of this example, since the number of so-called ceiling games is not set, the game does not shift to the advantageous state only by using the number of games in the normal state. On the other hand, an upper limit number of games is set for the advantageous state. When the number of games in the advantageous state reaches 1500G, which is the upper limit number of games, the advantageous state is immediately terminated and the normal state is entered regardless of whether or not the AT continues. That is, in the game of the slot machine 1, the advantageous state does not continue beyond the upper limit number of games.

  At the time of winning the advantageous state lottery by the internal winning of the single winning combination A, there are cases where the first advantageous state and the second advantageous state are shifted according to the lottery result of the first distribution lottery. . On the other hand, at the time of winning the advantageous state lottery by simultaneous winning of the bonus combination and the two-sheet combination, the first distribution lottery is not executed, and the transition to the second advantageous state is always generated.

  In the slot machine 1, the second advantageous state (second mode) can be shifted when a predetermined first transition condition is established in the normal state (first gaming state) when the advantageous state lottery (transition lottery) is won. On the other hand, transition from the first advantageous state (first mode) is impossible. In this example, in addition to the internal winning of the single winning combination A, the second advantageous state is distributed by the first distribution lottery, and the simultaneous winning of the bonus winning combination and the two winning combination shifts to the second advantageous state. Is set to the first transition condition described above.

  Hereinafter, in the case of (B-1) the winning of the advantageous state lottery by the internal winning of the single player A and the case of (B-2) the winning of the advantageous state lottery by the simultaneous winning of the bonus combination and the two-player combination The game state transition including the transition from the normal state to the advantageous state will be described separately.

(B-1) Advantageous state lottery winning by internal winning of single player A As shown in FIG. 7, an advantageous state lottery was won by internal winning of single player A (winning probability 1/50) under normal conditions. In this case, the above-described first distribution lottery for determining the number of state continuing games, which is the number of continuing games in the advantageous state, and the type of advantageous state is executed.

  In this first distribution lottery, the player is assigned to the first advantageous state with a probability of 98.4% and is assigned to the second advantageous state with a probability of 1.6%. Furthermore, the breakdown of the number of state continuation games when assigned to the first advantageous state is as follows: zero G (game) 69.5%, 100G 19.7%, 200G 6.9%, 300G 2. 3%.

  In the case of allocation to the second advantageous state, the number of state continuation games is not determined by the first allocation lottery and is not set. The transition of the gaming state in the case of the allocation to the second advantageous state is the same as the case of shifting to the second gaming state by simultaneous winning of the bonus combination and the two-piece combination. The case of allocation to the second advantageous state will be described in detail in the next section (B-2).

  When the first advantageous state is determined by the first distribution lottery (the number of state continuation games is zero G, 100G, 200G, or 300G), the first advantageous state is started. When the first advantageous state is started, AT (start AT) is performed until one navigation notification is executed. When the navigation notification by the AT is executed, if the number of state continuation games has been consumed, the above end condition is satisfied, and the state returns to the normal state after the AT ends.

  Therefore, if the first allocation lottery has been assigned to the first advantageous state with the number of state continuing games of zero G, the number of state continuing games has been consumed at the time of the navigation notification by the start AT, and 15 by the navigation notification. The first advantageous state ends when the winning combination can be won once. On the other hand, when the number of state continuation games by the first distribution lottery is 100G, 200G, or 300G, the number of state continuation games is undigested when executing navigation notification by the start AT. The AT is released without ending the first advantageous state. The first advantageous state after the AT is released is the same winning rate as in the normal state, but becomes a standby advantageous state (first mode standby state) that is executed every time the AT lottery with a winning probability of about 40% is used up to 10G. .

  When this AT lottery is won, the first AT is started. At the start of the first AT, the second sorting lottery is executed, and the number of AT continuing games of 10G to 50G is determined. While the first AT is continuing, an extra lottery that determines the number of extra games may be executed. When winning the extra lottery, the number of additional games is added to the number of AT continuing games, which is the number of continuing games of the first AT, and the number of continuing games under the first AT increases.

  In the case of the slot machine 1 of the present example, the combination of the allocation ratio of the AT continuing game number by the second allocation lottery, the execution frequency of the additional lottery, the allocation ratio of the additional game number by the additional lottery, etc. The number of games that can be digested from the occurrence of the first AT in the advantageous state to the end is about 20G.

  When the number of games set by the second distribution lottery or the extra lottery is digested and the first AT is completed, it is determined whether or not the number of state continuation games determined in the first distribution lottery has been digested. The If the number of state continuation games has been consumed, the end condition is satisfied, and the normal state is returned in accordance with the end of AT. On the other hand, if the number of state continuation games is undigested at the time when the first AT is finished, the state shifts to the standby advantageous state again while maintaining the first advantageous state. In this standby advantageous state, the AT lottery is executed every time 10G is digested as described above, and if the winning is made, the first AT is started again as described above.

  The first advantageous state (first mode) in the slot machine 1 of this example is divided into a first AT (special state) and a standby advantageous state (first mode standby state) in which the first AT is not generated. . In this first advantageous state, the first AT is started in response to the winning in the AT lottery in the standby advantageous state, and when the number of state continuation games has not been exhausted at the end of this AT, the state transition is made to return to the standby advantageous state. Repeatedly executed. Then, after the state transition is repeated, if the number of state continuation games has been consumed at the time when the AT ends, the first advantageous state ends and the normal state returns to the normal state when the end condition is satisfied.

  Note that the average number of games in the first advantageous state is 49G, and the expected value of the payout rate, which is the ratio of the number of acquired medals (safe) to the number of digested medals (out), is 105%. Expected play numbers for each number of games (number of state continuation games) by the first lottery lottery are minus 1 for 0G, 15 for 100G, 29 for 200G, and 44 for 300G.

(B-2) In the case of winning in the advantageous state lottery by simultaneous winning of the bonus combination and two-piece combination In the case of winning in the advantageous state lottery by simultaneous winning of the bonus combination and the two-piece combination, as shown in FIG. 2 Transition to an advantageous state occurs. In addition, as described above, even when the player is assigned to the second advantageous state by the above-mentioned first distribution lottery in accordance with the winning of the advantageous state lottery by the internal winning of the single role A (allocation rate 1.6%), Similarly, the transition from the normal state to the second advantageous state occurs.

  When the second advantageous state is entered, the second AT is started immediately. At the start of the second AT, the above-described second distribution lottery is executed, and the number of AT continuing games (500G to 1000G) is determined by lottery. Further, while the second AT is continuing, the above-described extra lottery is executed, and the number of additional games is determined and added to the number of AT continuing games that is the number of continuing games of the second AT. Thereafter, when the number of AT continuation games is exhausted in the second AT and reaches zero, the termination condition is satisfied, the second advantageous state is terminated, and the normal state is restored.

  The average number of games of the second AT under the second advantageous state is about 1000G including the addition. In addition, since the second AT always occurs under the second advantageous state, the expected value of the output rate in the second advantageous state is as high as 167%. As a result, the expected yield value in the second advantageous state is about 2000. As described above, in the slot machine 1, the AT generated in the second advantageous state (second mode) continues as compared with the AT (special state) generated in the first advantageous state (first mode). The average number of games as a period is advantageous to the player, and as a result, the AT generation condition is more advantageous in the second advantageous state than in the first advantageous state.

  In the game of the slot machine 1 configured as described above, an AT cannot be generated in a normal state, so that the expected value of the outgoing rate is suppressed to about 64% and does not exceed 100%. In this normal state, the player plays while expecting a transition to an advantageous state. Many players play while expecting to shift to the second advantageous state with the highest expected value. In addition, the numerical value of the payout rate including the payout rate of 64% in the normal state is the payout rate excluding the bonus amount.

  If you win the advantageous state lottery and move to the first advantageous state, you will not get a lot of balls compared to the second advantageous state, but the rate is higher than the normal state (about 105%), so continue the game If you do this, you can increase the number of balls. On the other hand, when it is possible to shift to the second advantageous state, the payout rate is higher than that of the first advantageous state (about 167%).

  That is, the player of the slot machine 1 plays for the purpose of shifting to the second advantageous state, but does not shift from the first advantageous state to the second advantageous state, and can only shift from the normal state. Therefore, the player of the slot machine 1 can play the game by considering the normal state as a chance zone (chance state) for shifting to the second advantageous state. Therefore, according to the slot machine 1, it is possible to suppress a decrease in gaming motivation even in a normal state, although the exit rate is lower than the first advantageous state.

  In order to make a strong impression to the player that the normal state is the chance zone, on the condition that it is the normal state, a message indicating that the chance zone can be shifted to the second advantageous state is displayed on the liquid crystal display unit 53. And good. In this case, it may be configured not to display the same message when the standby advantageous state under the first advantageous state in which the first AT is expected to be generated is occurring. According to such display setting, the player can be more strongly impressed that the normal state is the chance zone. As described above, the liquid crystal display unit 53 as the notification means does not notify that there is an opportunity to shift to the second advantageous state (second mode) in the standby advantageous state (first mode standby state), while in the normal state (first state). It is informed that it is a chance zone where there is an opportunity to shift to the second advantageous state on the condition that the game state).

  Note that the first advantageous state generated by the slot machine 1 cannot be shifted to the second advantageous state, but it is possible to maintain the willingness to play because the rate is higher than the normal state. As for the exit rate in the first advantageous state, it is desirable that the exit rate be higher than that in the normal state, and it is desirable to set the exit rate to be 100% or more so that the amount of balls is not reduced.

  Thus, in the game of the slot machine 1, the gaming state can be shifted between an advantageous state corresponding to an advantageous section where AT can be generated and a normal state corresponding to a normal section where AT is not generated. This normal state is a gaming state in which there is a possibility that a player's willingness to play may be reduced because the player does not shift to an advantageous state even if a predetermined number of games are executed as in the so-called ceiling. Further, in this slot machine 1, two types of advantageous states, a first advantageous state and a second advantageous state, in which a difference in the degree of advantage on the player side is set for the AT generation condition are set.

  In the slot machine 1, in the normal state, it is possible to shift to the second advantageous state where the AT generation condition is advantageous. On the other hand, from the first advantageous state where the AT generation condition is not advantageous to the second advantageous state. Migration is impossible. Under such a transition of the gaming state, the player can grasp the normal state as the chance zone for changing to the second advantageous state, so that it is possible to suppress a decrease in gaming motivation in the normal state. Even when the first advantageous state that cannot be shifted to the second advantageous state occurs, the player's willingness is greatly reduced because the player is more advantageous than the normal state because the AT can be generated if the first advantageous state occurs. There is no fear.

  As described above, the slot machine 1 of the present example can suppress a decrease in gaming motivation that can occur in a player under a normal state, and can maintain a high gaming motivation regardless of the type of gaming state that is occurring. It has a lot of playability.

  In the game of the slot machine 1, the duration of the second AT that can be generated in the second advantageous state is more advantageous for the player than the first AT that can be generated in the first advantageous state. For this reason, the second advantageous state is a more valuable gaming state for the player of the slot machine 1 of this example.

  In the slot machine 1, when a predetermined end condition is satisfied during the advantageous state, the slot machine 1 shifts to the normal state. In comparison between the first advantageous state and the second advantageous state, the average duration of the second advantageous state is longer than the average duration of the first advantageous state. Therefore, in the game of the slot machine 1, the second advantageous state can be changed to a more valuable gaming state, and the duration is relatively short even if the first advantageous state that cannot be regarded as a chance zone is entered. Transition to the normal state, which can be regarded as a chance zone, can be expected relatively early.

  The first advantageous state that occurs in the slot machine 1 is divided into an AT that is a special state and a standby advantageous state that does not generate an AT (first mode standby state). The slot machine 1 does not notify that it is a chance zone in which there is an opportunity to shift to the second advantageous state in this standby advantageous state, while it is a chance zone that can transition to the second advantageous state on condition that it is in the normal state Is notified. By performing such a chance zone notification, the player can be made to recognize that the normal state that should be regarded as the chance zone is the chance zone.

  In the slot machine 1, at least one of the AT generation conditions is satisfied when the normal state (first gaming state) is shifted to the advantageous state (second gaming state). (Starting AT, etc.) occurs. If such a configuration is adopted, for example, even when an internal rule is given such that instructions regarding winning (such as navigation notification of pushing order) are provided at least once when shifting to an advantageous state, there is no sense of incongruity It is possible to give instructions regarding winning.

  Further, if the start AT or the like is generated in response to the start of the advantageous state, the start AT or the like regardless of whether the number of games distributed at the start of the first advantageous state (number of state continuing games) is large or small. The advantageous state can be started in the same way. Therefore, in the game of the slot machine 1 that can be expected to win more games as the number of games in the first advantageous state increases, even if the number of games actually allocated is small, until the start AT and the like are large It is possible to maintain the player's expectation that the number of state continuation games has been distributed. On the other hand, for a player who wants to return to the normal state in the chance zone quickly, contrary to the above, even if the number of state continuation games actually allocated is large, until the start AT is over, the number of state continuation games is small It is possible to give the player a sense of expectation for numbers.

Instead of or in addition to the configuration of this example, the following configuration may be employed. Further, the following configurations may be combined as appropriate.
As the AT, the start AT, the first AT, and the second AT, which are different only in the number of continuous games and having no difference in the winning rate, etc. are illustrated. Different AT ratios may be set for each AT, and in this case, the AT ratio of the second AT may be advantageous to the player. That is, in order to make the second AT more advantageous to the player than the first AT, it is possible to make the rate of participation rather than the average number of games, and if at least one of the average number of games is advantageous, both may be advantageous. In this example, the start AT and the first AT are separated, but the first AT may be generated at the start of the first advantageous state.

  An example is shown in which the first distribution lottery is executed at the start of the first advantageous state to determine the number of continuing games (number of state continuing games) in the first advantageous state. Instead of this configuration, for example, a single winning combination A may be divided into a plurality of types, and the number of continued games in the first advantageous state may be distributed according to the type of the single winning combination A that is won internally. In addition, in this example, it is exemplified that the advantageous state is distributed according to the type of the winning combination, but the lottery method such as distributing the advantageous state by performing the lottery separately from the advantageous state lottery, etc. A lottery method may be adopted. Further, for example, if the number of continuous games in the normal state is 100G or more, it may be configured to shift to the second advantageous state in accordance with the winning of the advantageous state lottery. By adopting such a configuration, the game in the normal state Motivation is further improved.

  Although the configuration in which the second AT is always generated during the second advantageous state is illustrated, the standby advantageous state may be generated during the second advantageous state as in the first advantageous state. The frequency is more advantageous than the first advantageous state (for example, in the first advantageous state, the AT lottery is performed every 10G digestion, whereas the 5% digestion is performed, or the AT winning probability is more advantageous than the first AT. Or the like. Also, instead of the configuration of this example that shifts to the standby advantageous state in the first advantageous state, as in the second advantageous state, for example, the AT is continued by distributing the number of games at the start AT, The first advantageous state may be terminated when the AT is terminated. The occurrence condition of at least one AT among the duration, appearance rate, and occurrence frequency should be advantageous, for example, the player can expect more expected values in the second advantageous state than the first advantageous state. Any advantageous state may be configured.

  Although the configuration in which the state does not change between the first advantageous state and the second advantageous state has been illustrated, the transition from the first advantageous state to the second advantageous state may be possible. In this case, when the second transition condition that is difficult to be satisfied in the normal state (first game state) is satisfied in the first advantageous state (first mode) as compared with the first transition condition being satisfied. It may be possible to shift to the second advantageous state. By setting the second transition condition in this way, the transition probability is lower in the case of shifting from the first advantageous state to the second advantageous state than in the case of shifting from the normal state to the second advantageous state, etc. It is good to make it difficult to migrate. As the second transition condition, for example, it can be set that a specific winning combination is won internally under the first advantageous state, a predetermined transition lottery is won, or the like. It is sufficient that the probability that a specific combination is won internally in the first advantageous state, the probability of winning in the transfer lottery, or the like is lower than the probability that the first transition condition is satisfied in the normal state.

In this example, the AT that performs navigation notification of the pressing order as a special state is illustrated, but any AT may be targeted, such as notification of a winning symbol. For example, a special state such as ART or RT may be targeted.
Although it has been exemplarily shown that the start AT is always generated at the start of the advantageous state, for example, the AT is not necessarily generated at the start, such as the transition to the standby advantageous state at the start of the advantageous state.

A so-called periodic lottery in units of 10G has been exemplified as the AT lottery in the standby advantageous state, but an AT lottery may be adopted for each game. For example, when the number of ceiling games is set and the number of games corresponding to the number of ceiling games is played, the timing for shifting to the AT can be changed as appropriate.
The target gaming machine may be a so-called encapsulated or credit-type gaming machine that allows a game with points without using a gaming medium. Considering these, the description in the embodiment is expressed as a game value including a game medium and a score.
All illustrated numerical values, items, etc., such as the specifications and setting values of the gaming machine are examples, and any numerical values may be adopted. Moreover, it is good also as a structure which does not employ | adopt a part suitably, even if it illustrates how the structure illustrated was combined.
