Description

  The present invention relates to a slot machine capable of enabling any one of a plurality of setting values having different degrees of advantage.

  Conventionally, a slot machine having setting means for setting an internal winning probability of a combination in a plurality of stages has become common. In many slot machines, any one of six setting values of setting values 1 to 6 can be selected. The amusement store side operates the setting means to change the set value every day, and strives to ensure an appropriate profit.

  Many players play games while always inferring whether the set value of the slot machine with which they play is advantageous or unfavorable. In slot machine games, guessing of the set value is one of the funs in the game. For the purpose of further enhancing such enjoyment, a slot machine has been proposed in which a difference in appearance rate of specific effects is provided for each set value (see, for example, Patent Document 1). In this slot machine game, the set value can be estimated to some extent by observing the appearance frequency of a specific effect.

  However, the conventional slot machine has the following problems. That is, if the disparity for each set value of the appearance rate of the specific effect is excessive, the set value is accurately estimated at an early stage, and the slot machine with the disadvantageous set value may be avoided and the operating rate may be reduced. On the other hand, if the disparity for each set value of the appearance rate of specific effects is suppressed excessively, the difficulty of guessing the set value becomes too high, and the fact that the advantageous set value is used cannot be appealed to the player and the effect of attracting customers May be damaged.

JP 2007-236528 A

  The present invention has been made in view of the above-described conventional problems, and is a slot machine that can validate any of a plurality of setting values, and can appropriately set the estimation difficulty of the setting values. Is to provide a simple slot machine.

The present invention includes a symbol variation display means for variably displaying a plurality of types of symbols according to a predetermined arrangement in a plurality of symbol display areas,
Game start operation means operated by the player to start the game with the game medium inserted;
An internal lottery means for executing an internal lottery for determining an internal winning combination from a plurality of types of combinations when the game start operation means is operated;
A stop operation means operated by a player to stop the display of the variation of the symbol by the symbol variation display means;
When the stop operation means is operated, a display control means for drawing a symbol corresponding to the internal winning combination within a predetermined pull-in range and stopping and displaying it in the symbol display area;
Winning determination means for determining that a winning has occurred when a combination of symbols stopped and displayed in each symbol display area of the symbol variation display means matches a combination of symbols corresponding to the internal winning combination;
Profit granting means for granting a player a profit corresponding to the type of winning combination when it is determined by the winning determination means that a winning has occurred;
An internal lottery probability defining means for prescribing the probability of internal lottery by the internal lottery means for each set value of the multiple stages, so that a difference in the degree of advantage occurs according to a set value of a plurality of stages;
A set value selection means for selecting and validating any one set value from among the plurality of set values;
An operation data aggregation means for calculating operation data representing the degree of operation in a predetermined business period;
Operation determination means for determining whether the operation data aggregated by the operation data aggregation means is greater than or equal to a reference value or less than a reference value, every business day or each time the set value is changed;
Setting value determination that determines whether the setting value that has been validated during the business period corresponding to the operating data is more advantageous or disadvantageous than a predetermined reference setting value every business day or each time the setting value is changed Means,
A first execution probability with a large disparity for each set value of the plurality of stages, and a second execution with a small disparity for each set value of the plurality of stages. A specific performance probability defining means for defining the probability;
Depending on the combination of whether the operational data is greater than or less than the reference value and whether the set value is more advantageous or disadvantageous than the reference set value, the first execution probability and the second Execution probability selecting means for selecting any one of the execution probabilities of
A specific effect determining means for determining whether or not to execute the specific effect with the execution probability selected by the execution probability selecting means when the specific gaming state occurs;
A slot machine comprising: a specific effect executing means for executing the specific effect when execution of the specific effect is determined by the specific effect determining means (claim 1).

  In the game of the slot machine of the present invention, the specific effect is executed when execution of the specific effect is determined by the specific effect determining means in the specific game state. The specific effect determining means determines the execution of the specific effect with the execution probability selected by the execution probability selecting means among the first execution probability and the second execution probability.

  Comparing the first execution probability and the second execution probability, the first execution probability is set to have a larger disparity for each set value. Therefore, when the first execution probability is selected, it is relatively easy to estimate the set value according to the appearance frequency of the specific effect. On the other hand, when the second execution probability is selected, the difference in the appearance frequency of the specific effect according to the difference in the setting value is small, so that it is difficult to estimate the setting value.

  The execution probability selection means selects an execution probability according to a combination of whether the operation data is greater than or less than a reference value and whether the set value is more advantageous or disadvantageous than the reference set value. For example, if the operation data indicates high operation when the set value is advantageous, it is highly likely that the advantageous set value has been estimated by the player. In addition, if the operation data indicates low operation when the set value is disadvantageous, there is a high possibility that the disadvantaged set value was overlooked by the player. On the other hand, when the set value is disadvantageous and the operation is high, there is a high possibility that the disadvantageous set value is not overlooked, and when the set value is advantageous but the operation is low. Can be determined that there is a high possibility that an advantageous set value has not been estimated by the player.

  Thus, based on the combination of whether the operation data is greater than or less than a reference value and whether the set value is advantageous or unfavorable, it can be determined whether or not the player has estimated the set value. And if the execution probability in the said specific production | presentation determination means is set according to the judgment result, according to the estimation precision of the said setting value by a player, an estimation difficulty level can be set appropriately. For example, it is possible to adjust the degree of difficulty of estimation when the guess of the set value by the player is wrong, or increase the degree of difficulty of guessing when the guess is reversed.

  If the difficulty of guessing the set value is adjusted to be low in the slot machine, the fact that an advantageous set value is used can be appealed to the player and the effect of attracting customers can be enhanced. On the other hand, if the setting value estimation difficulty level is adjusted to be high, it is possible to avoid the possibility that the setting value is accurately estimated at an early stage, and the slot machine having the disadvantageous setting value is avoided and the operating rate is lowered.

The slot machine of the present invention may be a slot machine in a narrow sense using medals and coins as game media, or a parrot (R) using pachinko balls as game media.
Further, the specific effect may be one type or two or more types. When two or more types of specific effects are set, the specific effect determining means may be configured to determine whether or not to execute each specific effect. At this time, when the specific gaming state occurs, one of the specific effects may be executed with a probability of 100%, but a case where no specific effect is executed may be set.

In addition, the specific game state is a state in which a specific combination among the plurality of types of combinations is determined as the internal winning combination, and the specific effect suggests to the player that the specific combination has been won internally. It is preferable to be a production (claim 2).
In this case, the specific effect is executed as a suggestion effect indicating that the specific combination is won internally.
In addition to the above, as the specific gaming state, a bonus state that increases the internal winning probability of the small role, a replay high probability state that increases the internal winning probability of the replay role, and the like may be set.

The operation data is preferably any one of the number of games executed, the cumulative number of inserted game media, and the number of times a winning has occurred.
Since the number of games, the total number of game media inserted, and the number of winnings all increase monotonously as the game continues, the number of games can be used as the operation data representing the operation level of the slot machine. As the operation data, in addition to the above, the number of payouts of game media can be used.

In addition, the execution probability selection means, when the operation data is greater than or equal to the reference value, and the set value is more advantageous than the reference set value, and the operation data is less than the reference value, and , If the set value is less favorable than the reference set value, the second execution probability is selected while
When the operating data is greater than or equal to the reference value and the set value is more disadvantageous than the reference set value, and the operating data is less than the reference value, and the set value is more than the reference set value If it is also advantageous, it is preferable to select the first execution probability.

  In this case, in the situation where the set value is accurately estimated, the difficulty of estimating the set value can be increased. On the other hand, in a situation where the set value is not estimated correctly, the difficulty of estimating the set value can be suppressed.

  The slot machine of the present invention is a slot machine that can validate any of a plurality of setting values, and can set the estimation difficulty of the setting values appropriately.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example is an example related to the slot machine 1 that can validate any of the setting values 1 to 6. 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. A front side portion on the player side in the slot machine 1 is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 includes a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 arranged above 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 right side of the symbol display window 11, a payout amount display portion 551 and a credit display portion 552 are arranged.

  The base portion 100 is formed so as to protrude relatively with respect to the symbol display window 11 located behind the player. The base portion 100 has a shelf-like operation surface 14 at the upper end adjacent to the symbol display window 11, and has a medal tray 15 for paying out medals at the lower end, and between the operation surface 14 and the medal tray 15. The operation panel 13 is provided.

The operation surface 14 includes a bet button 64 for inserting medals into the game, a settlement button 65 for paying out credited medals, and a medal insertion slot 630 for directly inserting medals. Has been placed.
The operation panel 13 is provided with a start lever 62 (game start operation means) for starting the symbol fluctuation of the reel 21 and a stop button 61 (stop operation means) for stopping the symbol fluctuation.

  The bet button 64 is a button for inserting a predetermined number of medals out of credited medals. In a normal state limited to 3 BETs (three betting games), a 3-bet signal representing the number of throws 3 is generated according to the operation of the bet button 64. On the other hand, in a bonus state limited to 2 BET (two betting games), a 2-bet signal is generated in response to the operation of the bet button 64. However, when the remaining credit is insufficient, a bet signal corresponding to the remaining credit is generated, and when the credit is zero, no bet signal is generated.

  The start lever 62 is an operation lever that generates a game start signal that is a control signal for the reel 21 in accordance with the player's operation. In the slot machine 1, when a predetermined number of medals are inserted by direct insertion of medals or operation of the bet button 64, the start lever 62 is set to an effective state. When the replay winning combination is won, a state is set in which a medal is directly inserted or a medal is automatically inserted without a betting operation, that is, a state where the next game can be started.

  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 horizontal winning lines 211 to 213 and diagonal winning lines 214 and 215. In the slot machine 1 of this example, all five pay lines are always set to be valid regardless of the number of BETs for the game.

  Reels 21L, C, and R constituting the symbol variation display means 2 are arranged on the back side of the symbol display areas 110L, C, and R, respectively. As shown in FIG. 3, the reels 21 </ b> L, C, and R are rotary reels having a cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof at substantially constant intervals. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

  As shown in FIG. 1, the stop button 61 is an operation button that generates a fluctuation stop signal that is a control signal for the reel 21 in accordance with the player's operation. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

The number-of-payout display unit 551 is a display unit that displays the number of medals (game media) to be paid out at the time of winning a prize. It should be noted that the setting value is displayed on the payout amount display section 551 in the setting value changing operation.
The credit display unit 552 is a display unit that displays the number of credits that is the number of medals credited (stored) by the credit function.

The speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light.
The liquid crystal display unit 53 includes a liquid crystal display and can display various effect screens. In particular, the liquid crystal display unit 53 of this example has a function as the specific effect execution means 7 and can display specific effect screens 71 to 73 to be described later with reference to FIGS.

Next, the role of the slot machine 1 of this example will be described.
In the slot machine 1 of this example, as shown in FIG. 4, four types of small combinations such as a bonus combination (BB1 combination, BB2 combination), 15-sheet combination, and a replay combination are set. In FIG. 4, the name of each combination is shown in the left column, the winning symbol that is a combination of the symbols 20 corresponding to each symbol is shown in the middle column, and the profit given to the player according to the winning is shown in the right column. The profit in the “3 BET” column is a profit when winning in a normal state. The profit in the “2 BET” column is a profit when winning in a bonus state. In the bonus state, a payout of 15 medals is set as a profit regardless of the type of a winning combination.

As the bonus state, a BIG1 state triggered by the BB1 role and a BIG2 state triggered by the BB2 role are set. The BIG1 state and the BIG2 state differ only in the role that triggers the occurrence, and share other game specifications. The bonus state ends when the number of medals paid out exceeds 400, which is the specified number of payouts (specified number of grants).
Also, in this example, as a specific combination for a specific performance that indicates that an internal winning has been made, a 15-piece combination with a winning pattern of “watermelon” is set, and the internal winning state of the specific combination is a specific game It is set as a state.

  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 above-described configuration, the inserted medal detection unit 63 that detects a medal inserted directly through the medal slot 630 (FIG. 1), the reel 21 A reel driving unit 22 constituting the symbol variation display means 2, a reference position detecting unit 66 for detecting the rotational position of the reel 21, a medal paying unit 54 for paying out medals, a payout number display unit 551 and a credit number display unit 552 are included. Various display units 55, a set value operation unit 68 for validating any one of the set values, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 is a detection unit for a medal inserted directly from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion unit 630. In the slot machine 1 of this example, when a predetermined number of medals are inserted by direct insertion of medals or operation of the bet button 64, the start lever 62 is set to an effective state and a new game can be started. It becomes a state.

The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is a driving unit that 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 medal payout unit 54 is a payout unit that pays out a predetermined number (see FIG. 4) of medals in accordance with winning.

  The set value operation unit 68 (set value selection means) includes a key cylinder 681 for inserting a set key 680, a select button 682 for selecting any set value, and a decision button 683 for validating the selected set value. ing. These are all arranged on an operation panel (not shown) inside the front frame 10 (FIG. 1). In a state where the setting key 680 inserted into the key cylinder 681 is rotated to the right, the set value is displayed on the payout amount display portion 551 and the selection button 682 and the determination button 683 can be operated. In this state, every time the selection button 682 is pressed, the setting value display of the payout amount display section 551 can be switched in order. If the enter button 683 is pressed while the desired set value is displayed, the set value is validated, and the set value is determined according to the extraction of the setting key 680.

  As shown in FIG. 5, the control unit 3 includes a CPU 31, ROM 33 and RAM 34 as memory means, an I / O unit 32 as an input / output interface, and a random number extraction unit 35 that extracts random numbers for internal winning combination lottery. And a random number generator 350 for generating random numbers. The CPU 31 executes a software program read from the ROM 33 to thereby execute an internal lottery unit 41 for lottering an internal winning combination, a flag erasing unit 410 for controlling a flag corresponding to the internal winning combination, and a display control unit 42 for controlling the reel 21. , A winning determination means 43 for determining a winning symbol, a profit giving means 44 for giving a profit in accordance with the winning, a specific effect determining means 45 for determining a specific effect pattern, an operation data aggregating means 48 for totaling operation data, and determining operation Each function is realized as an operation determination unit 461 for performing a setting value determination unit 462 for determining a set value and an execution probability selection unit 47 for selecting an execution probability of a specific effect.

  In the storage area of the RAM 34, which is a memory means, a game number counter 341 is provided for storing the cumulative number of games counted by the operation data totaling means 48 as operation data. The operation data totaling means 48 sets an initial value zero game in the game number counter 341 in response to the start of business, and adds the cumulative number of games in the game number counter 341 for each game until the store is closed. That is, in this example, one business day is set as a business period in which the cumulative number of games, which are operation data, is totaled. When the store is closed, the total number of games at that time is stored in a flash ROM (not shown) together with the setting value of the day.

The ROM 33, which is a memory means, has an internal lottery probability defining means 331 for storing an internal winning combination lottery table (FIG. 6) applied to an internal winning combination lottery, and an effect table (FIG. 7) applied to a specific effect execution lottery. ) Is stored, and a reel control table (not shown) applied to stop control of the reel 21 is stored.
The reel control table is a data table in which stop positions that can be stopped on the winning line are defined.

  The internal winning combination lottery table is a lottery table for determining an internal winning combination by lottery. 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. The internal winning combination lottery table includes a table applied to the normal state shown in FIG. 6 and a table (not shown) applied to the bonus state. The internal winning combination lottery table for the normal state is defined for each of the setting values 1 to 6, but in the figure, the table corresponding to the most advantageous setting value 6 and the table corresponding to the most unfavorable setting value 1 are shown. Only shown. In the figure, among the columns corresponding to each set value, the left column in the vertical direction indicates the number of winning random numbers, the middle column indicates the internal winning probability by the denominator (1 / x of x), and the right column. Indicates an expected value obtained by multiplying the number of payouts according to the winning by the internal winning probability.

  As can be seen from FIG. 6, the set value 6 table is advantageous in that the number of winning random numbers for the bonus combination, the two-piece combination, the eight-piece combination and the fifteen-piece combination is defined more than the set-value one table. Yes. As a result, in the table of setting value 6, the payout rate greatly exceeds 100%, which is very advantageous.

  As shown in FIG. 7, the effect table is a lottery table for execution lottery for determining the effect pattern of the specific effect that suggests that the 15-character combination that is the specific combination has won internally. In the effect table, each random number of 0 to 255 for execution lottery is distributed as a winning random number of effect patterns 1 to 3 to be described later with reference to FIGS. The execution probability of each effect pattern is determined according to the number of winning random numbers assigned. In the effect table, a winning random number for each effect pattern is set for each set value. Furthermore, in this example, the first table in which the number of winning random numbers for each effect pattern varies greatly according to the set value and the second table in which the difference for each set value for the number of winning random numbers in each effect pattern is small It is set as a table.

  As shown in FIG. 5, the random number extraction unit 35 is an extraction unit that extracts random numbers for lottery from random numbers generated by the random number generation unit 350. As random numbers for lottery, there are random numbers for internal winning combination lottery extracted from random numbers of 0 to 65535, and random numbers for execution lottery extracted from random numbers of 0 to 255. The random numbers for the internal winning combination lottery are extracted at the start of the game. The random number for the execution lottery for determining the specific effect pattern is extracted according to the internal winning of the 15 winning combination which is the specific winning combination.

  As shown in FIG. 5, the internal lottery means 41 is a means for determining an internal winning combination by internal lottery and establishing an internal winning flag corresponding to the internal winning combination. The internal lottery means 41 collates the random numbers for internal winning combination lottery against the winning random numbers of each combination specified in the internal winning combination lottery table (for example, FIG. 6), and determines the internal winning combination. The internal lottery means 41 selects and uses any of the internal winning combination lottery tables according to the gaming state and the set value.

  The flag erasure unit 410 is a unit that controls the internal winning flag. The flag erasure unit 410 sets an internal winning flag of a role other than the bonus combination to an off state (zero) before starting the next game regardless of whether or not the game is won for the first time. 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, for the bonus combination flag corresponding to the bonus combination, the flag establishment state is sequentially carried over to the next game until winning, and is reset to the off state according to the winning.

  The specific effect determining means 45 is a means for executing an execution lottery of the specific effect pattern when the 15 winning combination that is the specific combination is won internally (specific game state). The specific effect determining means 45 determines the specific effect pattern by collating the random numbers for execution lottery with the first table or the second table (FIG. 7). When the first table is applied to the execution lottery, the disparity for each set value of the execution probability of each effect pattern increases. On the other hand, when the second table is applied to the execution lottery, the disparity for each set value of the execution probability of each effect pattern is reduced. The first table or the second table is selected by the execution probability selecting means 47 described later.

  As shown in FIG. 5, the display control means 42 is a means for starting the symbol fluctuation of the reel 21 in response to the game start signal and stopping the symbol fluctuation of the reel 21 in response to the fluctuation stop signal. The display control means 42 inputs a control pulse to the stepping motor that constitutes the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control means 42 counts the number of control pulses input to the reel driving unit 22, that is, the number of steps rotated by the stepping motor. In particular, the display control means 42 of this example counts the number of steps generated after the most recent detection signal by resetting the number of steps to zero each time the detection signal of the reference position piece of each reel 21 is fetched.

  The display control means 42 performs so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine authorization and type verification, etc.) are stopped on the winning line. In this example, a range corresponding to 4 symbols is set as the pull-in range. The display control means 42 determines the stop position by collating the number of steps when the variable stop signal is taken into the reel control table in which the stop position that can be stopped on the winning line is defined. The display control means 42 pulls the symbol corresponding to the established flag to the determined stop position and stops the reel 21.

  The winning determination means 43 is a means for determining whether or not the combination of symbols stopped and displayed by the three reels 21L, 21C, 21R is a predetermined winning symbol. Specifically, the winning determination means 43 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 43 takes in the number of steps of each corresponding stepping motor (reel drive unit 22) after each reel 21L, C, R stops. The winning determination means 43 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20.

  The profit granting means 44 is a means for giving a profit in accordance with the winning. For example, the profit granting unit 44 grants a profit of paying out 15 medals when a winning combination of 15 sheets is determined in a normal state. When the winning combination of the BB1 combination or the BB2 combination is determined, a benefit of occurrence of a bonus state is given.

The operation determination unit 461 is a unit that determines the operation of the previous business day when power is turned on in preparation for opening a game hall. The operation determination unit 461 determines whether the cumulative number of games read from a flash ROM (not shown) is greater than or less than the reference value of 3001 games.
The set value determining means 462 is a means for determining the set value of the previous business day when the power is turned on in preparation for opening a game hall. The setting value determination unit 462 determines whether the setting value read from the flash ROM (not shown) is a high setting that is more advantageous or a disadvantageous setting than the reference setting value. In this example, an intermediate value 3.5 between the setting value 3 and the setting value 4 is set as the reference setting value.

  The execution probability selection means 47 is a means for selecting whether to apply the first table or the second table as an effect table to be applied to an execution lottery of a specific effect pattern. The execution probability selection means 47 selects an effect table according to the selection table of FIG. For example, if the setting value determining means 462 determines that the setting is high and the cumulative number of games is determined to be less than 3001, the determination is that the setting value has not been correctly estimated, and the first table is selected. To do. If it is determined that the setting is high and the cumulative number of games is determined to be 3001 or more, it is determined that the set value has been ignored, and the second table is selected.

  The operation of the slot machine 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 9 is a flowchart showing the flow of the effect table selection process. FIG. 10 is a flowchart showing the flow of the specific effect execution process.

  As shown in FIG. 9, in the effect table selection process, first, power-on is determined (S101). When the power is turned on (S101: YES), it is determined whether or not the date has been updated (S102). For example, if the date has been updated (S102: YES), such as when the power is turned on for business preparation for the day (S102: YES), the cumulative number of games for the previous day is read (S103), and the setting value for the previous day is read. (S104). The read cumulative game number and the set value are collated with the selection table (FIG. 8) (S105), and an effect table to be applied to a specific effect pattern execution lottery is selected from the first table to the second table (FIG. 7). Selected (S106).

  As shown in FIG. 10, in the specific effect execution process, first, it is determined whether or not 15 specific combinations, which are specific combinations, have won internally (S201). When the 15 winning combination is won internally (S201: YES), a random number for execution lottery of a specific effect pattern is extracted (S202) and collated with the effect table selected in step S106 (FIG. 9) ( S203). The specific effect pattern determined in this way is set (S204), and the corresponding specific effect screen is displayed (S205).

The specific effect patterns include effect patterns 1 to 3 corresponding to the first to third specific effect screens 71 to 73 shown in FIGS.
As shown in FIG. 11, the first specific effect screen 71 by the effect pattern 1 is displayed with the symbols 711 of “cherry”, “watermelon”, “orange”, and “RP”. This is an effect screen that displays that either the 15-sheet combination or the replay combination has been won internally.

As shown in FIG. 12, the second specific effect screen 72 based on the effect pattern 2 is an effect of displaying that the winning combination of 2 or 15 is displayed internally by the display 721 of each symbol of “cherry” and “watermelon”. It is a screen.
As shown in FIG. 13, the third specific effect screen 73 based on the effect pattern 3 is a display screen that clearly notifies that the 15-character combination, which is the specific combination, has been won internally by a “watermelon” display 731.

  Here, when the first table is selected as the effect table (FIG. 7) in displaying these specific effect screens 71 to 73, the execution probabilities of the respective effect patterns vary greatly according to the set values. In this case, it is relatively easy to estimate the set value according to the appearance frequency of each effect pattern. On the other hand, when the second table is selected as the effect table, the disparity for each set value of the execution probability of each effect pattern is reduced. In this case, it is difficult to estimate the set value from the difference in the appearance frequency of each effect pattern. In this example, as in the selection table of FIG. 8, the first table is selected when it is determined that the setting value of the previous day has not been ignored. On the other hand, the second table is selected when there is a high possibility that the setting value of the previous day is overlooked.

  In the slot machine 1 of this example configured as described above, it is possible to appropriately set the estimation difficulty level of the setting value based on the setting value of the previous day and the operation data of the previous day. In this slot machine 1, since the difficulty of estimating the set value can be maintained at an appropriate level, it is possible to expect an effect that it is possible to satisfy both the demands on the game store side and the player side. That is, according to this slot machine 1, the fact that an advantageous set value is used can be appealed to the player, and the possibility that an unfavorable set value is detected at an early stage and the operating rate is lowered can be avoided. .

In this example, the 15-sheet combination is set as the specific combination, and the suggestion effect that the 15-sheet combination is won internally is set as the specific generation. It is also possible to set another suggestion, bonus combination, etc. as a specific combination, and to set a suggestion effect when the specific combination is won internally as a specific effect.
In addition, in this example, three specific effect patterns are set as specific effects suggesting that the specific role has been won internally, and when the specific role is won internally, one of them is executed with a probability of 100%. This is an example. Instead of this, it may be set that the specific effect is not executed at all even if the specific combination is won internally. Furthermore, instead of this example, one type of specific effect may be set, and it may be determined whether or not to execute the specific effect in the execution lottery.
Further, the content of the specific effect is not limited to this example. An effect by voice may be used as the specific effect, or a specific effect that combines the display of the effect screen and the sound may be employed.

  This example is an example in which the cumulative number of games is adopted as operation data representing the degree of operation. As the operation data, instead of this example, for example, the total number of medals inserted, the number of bonus winnings, etc. can be adopted. In short, any data may be used as long as the game data reflects the amount of operation.

In this example, it is determined whether or not the date has been changed when the power is turned on, so that it is determined that the power is turned on due to business preparation on the current day, and the effect table is switched every business day. Instead, the effect table can be switched only when the set value is changed. Alternatively, in addition to every business day, the effect table may be switched when the set value is changed.
In this example, the internal winning probability of the bonus combination and the small combination is set to be different for each set value. However, the internal winning probability may be changed for each set value for only the bonus combination or only the small combination. .

  As described above, specific examples of the present invention have been described in detail as in the first embodiment, but these specific examples merely disclose an example of the technology included in the scope of claims. Needless to say, the scope of the claims should not be construed as limited by the configuration, numerical values, or the like of the specific examples. The scope of the claims includes techniques obtained by variously modifying or changing the specific examples using known techniques, knowledge of those skilled in the art, and the like.
