Description

  The present invention relates to a slot machine in which a player can select the number of game media inserted in one game.

  Conventionally, a slot machine is known in which a player can select the number of game media inserted in one game and the lottery probability of any of the combinations varies depending on the number of games inserted (for example, Patent Document 1). reference.). Such a slot machine is trying to realize a variety of playability by setting a plurality of inputs to the game. It is to be noted that in a slot machine in which the number of throws can be selected, it is general that the payout rate, which is the ratio of the number of payouts to the number of throws, is the same regardless of the number of throws. If the payout rate is approximately the same, the greater the number of inputs, the higher the expected number of payouts and the higher the shooting performance.

  However, the conventional slot machine has the following problems. In other words, as described above, the number of throws can be selected and the slot machine designed to have the same payout rate has many players who demand high shooting characteristics, and the maximum throws in actual games. There is a fact that there are very few players who choose the number of inputs other than the number. Thus, in the conventional slot machine, a game with the number of inputs other than the maximum number of inputs is not fully utilized, and there is a possibility that it is not useful for improving the fun of the game.

Winning determination means for determining whether a combination of symbols stopped and displayed in each symbol display area of the symbol variation display means is a predetermined winning symbol;
Profit granting means for granting a player a profit corresponding to the winning symbol when it is determined by the winning determining means that the symbol is a winning symbol,
The internal lottery means determines the first internal lottery and the second internal lottery according to the game start operation means in a state where a third prescribed number of game media, which is the sum of the first prescribed number and the second prescribed number, is inserted. An internal lottery is executed in a slot machine (claim 1).

  The internal lottery means in the slot machine of the present invention executes the first internal lottery in response to the insertion of the first prescribed number of game media, and the second internal lottery in response to the insertion of the second prescribed number of game media. Run a lottery. The first internal lottery and the second internal lottery have different lottery probabilities for at least one of the combinations.

  In the slot machine, a game with the third specified number, which is the sum of the first specified number and the second specified number, is possible. When the third specified number of game media is inserted, the internal lottery means executes two types of internal lottery, the first internal lottery and the second internal lottery, and determines an internal winning combination for each internal lottery. .

In the third prescribed number of games in the slot machine, a combination of the first prescribed number of games and the second prescribed number of games is realized. The player can simultaneously enjoy two types of game play by inserting the third specified number of game media.
As described above, in the slot machine of the present invention, it is possible to enjoy various games by selecting the number of game media inserted, and the interest of the game is improved.

Further, the display control means may be configured such that in the game in which the third specified number of game media is inserted,
If the first small combination is determined as an internal winning combination by the first internal lottery and the second internal lottery is lost, the symbol is stopped and displayed so that the first small combination wins,
If the first internal lottery is lost and the second small combination and the third small combination are simultaneously determined as internal winning combinations by the second internal lottery, the second small combination will win Stop displaying symbols,
When the first small combination is determined as an internal winning combination by the first internal lottery and the second small combination and the third small combination are simultaneously determined as internal winning combinations by the second internal lottery Stops the symbol so that the third small role wins,
Preferably, the profit granting means grants a profit larger than the profit according to the winning of the first small role and the profit according to the winning of the second small role according to the winning of the third small role ( Claim 2).

  In the game in which the third prescribed number of medals are inserted, if either of the winning combinations is won in the first internal lottery and the second internal lottery, both of the winning combinations cannot be won. Profit may be lost. Therefore, as described above, when the internal winning combination is determined in both the first internal lottery and the second internal lottery, the internal winning combination is determined in one of the internal lotteries, and the other internal lottery is lost. If it is set so that a winning combination that is more advantageous than that in the case of winning is made, it is possible to avoid the possibility that the player's profit is impaired as described above.

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 start a game in response to the insertion of a prescribed number of medals from one to three. 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. In the slot machine 1, the front portion facing the player 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 number display unit 551 for displaying the payout number of medals (game media) and a credit number display unit 552 for displaying the credit amount 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 table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 for paying out medals at the lower end, and between the operation surface 14 and the medal tray 15. An operation panel 13 is provided.

  On the operation surface 14, a bet button 64 for inserting a medal credited (stored) by a credit function, a settlement button 65 for paying out a credited medal, and a medal insertion for directly inserting a medal A mouth 630 is disposed. The operation panel 13 includes a start lever 62 (game starting operation means) for starting the symbol variation of the reel 21 (variation display portion) and a stop button 61 (stop operation means) for stopping the symbol variation. Has been placed.

  The bet button 64 is a combination of a 1 bet button 641, a 1 bet button 642, and a max bet button 643. Each of the bet buttons 641 to 643 is a button for inserting a credited medal. Each of the bet buttons 641 to 643 generates a 1 to 3 bet signal representing the number of throws 1 to 3 in accordance with the operation. However, if the remaining credit is insufficient, a 1 or 2 bet signal corresponding to the remaining credit number is generated. If the credit is zero, no bet signal is generated regardless of which bet button 64 is operated.

  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, a startable state in which the start lever 62 can be effectively operated is set on the premise that a predetermined number of medals are directly inserted or a predetermined number of medals are inserted by operating the bet button 64 or the like. When the start lever 62 is operated in a state where one, two, or three medals are inserted, a one-sheet insertion game, a two-sheet insertion game, and a three-sheet insertion game are started.

  The stop button 61 is an operation button that generates a variable 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.

  As shown in FIG. 1, 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. 1, 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.

  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. The reels 21L, 21C, and 21R are rotary reels having a cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof with a substantially constant interval. On each reel 21, symbols are arranged as shown in FIG. 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 speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light.
The number-of-payout display unit 551 is a display unit that displays the number of medals paid out at the time of winning a prize.
The credit number display unit 552 is a display unit that displays the number of medals credited (stored) by the credit function.
The liquid crystal display unit 53 includes a liquid crystal display. The liquid crystal display unit 53 displays various effect screens as the game progresses.

Next, an outline of the role, symbol arrangement, and game play of the slot machine 1 of this example will be described.
In the slot machine 1, roles are set as shown in FIG. In the figure, in order from the left column, the names of the winning combinations, winning symbols that are combinations of symbols 20 corresponding to the winning combinations, and profits given to the player in accordance with winnings are shown. The winning symbol consists of a combination of three symbols, left, middle and right. In the two right columns, the winning combinations that can be won in the first internal lottery and the second internal lottery are indicated by ◯.

  In addition to bonus combinations A and B, 15 combinations, 9 combinations, small combinations such as 1 combination A and B, and replay combinations are set as combinations. In this example, the bonus combination A, 15 combination, nine combination, eight combination, two combination and one combination A are set as the combinations that can be won internally in the two-loading game in which only the second internal lottery is executed. Has been. In addition, a bonus combination B, a seven-piece combination, and a one-piece combination B are set as the combinations that can be won internally in a one-insert game in which only the first internal lottery is executed. As for the replay role, internal winning is possible in both the two-player game and the one-player game. Note that in a three-card game in which both the first internal lottery and the second internal lottery are executed, there is a possibility that all winning combinations will be won internally.

  Next, the outline of the game play of the slot machine 1 will be described. In the slot machine 1, different internal lottery is executed for the one-sheet insertion game and the two-sheet insertion game. In the three-card insertion game, both the first internal lottery executed in the one-card insertion game and the second internal lottery executed in the two-card insertion game are executed. In the three-card insertion game, a game like a combination of the game characteristics of the one-card insertion game and the game characteristics of the two-card insertion game is realized.

  In the three-card insertion game, there is a possibility that the winning in the first internal lottery and the winning in the second internal lottery may overlap. In the slot machine 1 of this example, the winning combination varies depending on the combination of the first internal lottery and the second internal lottery. Note that the game playability of the slot machine 1 of this example will be described in detail later with reference to FIG.

  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 setting a set value representing the player's degree of advantage, 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 slot 630. In the slot machine 1 of this example, when a medal is inserted by direct insertion of a medal or bet button operation, a startable state in which a game can be started is set according to the operation of the start lever 62.

The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is means for rotating 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 the number of medals according to the winning combination (see FIG. 3). For example, when nine winning combinations are winning combinations, nine medals are paid out.
The set value operation unit 68 is an operation unit for changing set values of 6 stages having different lottery probabilities such as bonus combinations using the setting key 680.

  As shown in FIG. 4, 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, a random number generation unit 350 for generating random numbers, and a random number for extracting random numbers. And an extraction unit 35. 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 control unit 410 for controlling a flag corresponding to the internal winning combination, and a display control unit 42 for controlling the reel 21. Each function is realized as a winning determination unit 43 that determines whether or not the combination of symbols that are stopped and displayed is a winning symbol, and a profit granting unit 44 that grants a profit according to the winning.

The ROM 33 which is a memory means stores an internal winning combination lottery table (FIGS. 5 and 6) used for lottery of an internal winning combination and a reel control table (not shown) used for stop control of the reel 21.
The reel control table is a table in which stop positions that can be stopped on the pay lines 211 to 215 are defined.

  The internal winning combination lottery table is a lottery table for determining an internal winning combination by lottery. As the internal winning combination lottery table, a table (FIG. 5) applied to the second internal lottery executed in the two-player game under the normal state and the first internal executed in the one-player game under the normal state There is a table (FIG. 6) applied to the lottery. In the internal winning combination lottery table, winning random numbers for each combination are defined within a predetermined random number range. The first internal lottery and second internal lottery tables are set for each set value of 1 to 6, respectively. In addition to the internal winning combination lottery tables shown in FIGS. 5 and 6, a bonus state table (not shown) is prepared.

  In the internal winning combination lottery table for the second internal lottery, as shown in FIG. 5, in addition to the single winning random number in which the bonus combination A and the replay combination are each independently winning, four types of winnings in which multiple winning combinations are simultaneously won internally. A random number is specified. There are two types of combinations of small winning combinations that are won internally: a combination of eight, nine, and fifteen, and a combination of one, combination A, two, and eight. Furthermore, with respect to these two types of combinations, a case where the bonus combination A is won simultaneously and a case where the bonus combination A is not won simultaneously is set.

  In the internal winning combination lottery table for the first internal lottery, as shown in FIG. 6, in addition to the single winning random number in which the bonus combination B, the 7-sheet combination, the 1-sheet combination B, and the replay combination are each independently won, the bonus combination B And a simultaneous winning random number for a bonus combination B and a single winning combination B are defined.

As shown in FIG. 4, the random number generator 350 is a part that generates random numbers belonging to a predetermined integer range. The random number generator 350 generates random numbers belonging to a predetermined range for internal winning combination lottery. There are two types of random number generators 350 for the first internal lottery and the second internal lottery. The random number generator 350 generates random numbers at different periods. Therefore, in the slot machine 1, there is a possibility that an internal winning will occur in both the first internal lottery and the second internal lottery. If the random number generator 350 is of one type, both the first internal lottery and the second internal lottery can be performed by changing the random number generation timing or by overlapping the winning random numbers in the internal winning combination lottery table. Can give the possibility of internal winning.
The random number extraction unit 35 is a part for extracting random numbers for lottery. The random number extraction unit 35 extracts random numbers for lottery from the random numbers generated by the random number generation unit 350. The random number extraction unit 35 extracts a random number for internal winning combination lottery triggered by the game start signal corresponding to the operation of the start lever 62.

  The internal lottery means 41 is a means for determining an internal winning combination by internal lottery and establishing a flag corresponding to the internal winning combination. The internal lottery means 41 selects an internal winning combination lottery table in accordance with the game state being generated and the number of throws, determines the internal winning combination by collating the random numbers for the internal winning combination lottery, and corresponds to the internal winning combination The flag to be established is established.

  The flag control means 410 is a means for controlling an internal winning flag corresponding to the internal winning combination. The flag control means 410 is in an off state (zero) until the next game is started regardless of whether or not the internal winning flag corresponding to a role other than the bonus combination is won in the game in which the flag is established for the first time. Reset to. 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 which is an internal winning 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. In the state where the bonus combination flag is carried over, the internal lottery of the same type of bonus combination is not executed, and only the internal lottery of the bonus combination for which the flag is not established is executed.

  As shown in FIG. 4, 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 collates the number of steps when the fluctuation stop signal is taken in with the reel control table, and determines the stop position. The display control means 42 pulls the symbol corresponding to the determined stop position and stops the reel 21.

  The winning determination means 43 is a means for determining a symbol combination that the three reels 21L, 21C, 21R stop display. Specifically, the winning determination means 43 determines the winning / losing according to the symbol combination 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 stepping motor (reel driving unit 22) corresponding to the reels 21L, C, R after the reels 21L, C, R stop. The winning determination means 43 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 on the basis of the number of steps, and determines the type of winning combination, the loss, etc. for the symbol combination.

  The profit granting means 44 is a means for giving a profit according to the winning combination determined by the winning determination means 43. For example, when the bonus combination is a winning combination, the profit granting unit 44 provides a profit that a bonus state occurs. If the nine winning combination is a winning combination, a benefit of paying out nine medals is given. When the replay combination is a winning combination, medals for a new game are automatically inserted. Thus, a replay game that can be executed without the player inserting medals is provided. When the replay winning combination is won, the same number of medals as the number inserted for the game are automatically inserted into the replay game. For example, when a replay role is won in a three-card insertion game, a three-card insertion game is awarded as the replay game. Note that the bonus state of this example ends in response to the payout of over 300 medals.

Next, the playability of the slot machine 1 will be described with reference to FIG.
In the two-card insertion game in which the second internal lottery using the internal winning combination lottery table of FIG. 5 is executed, there may be an internal winning combination of 8 winning combinations + 9 winning combinations + 15 winning combinations. If there is an internal winning combination of 8 + 9 + 15 + without simultaneously winning bonus combination A, the 8 winning combination will always win. Similarly, when a single combination A + 2 double combination + 8 combined combination is won internally without simultaneous winning of the bonus combination A, the single combination A always wins.

  In the three-card insertion game in which the first internal lottery using the internal winning combination lottery table of FIG. 6 is executed in addition to the second internal lottery, the seven internal winning combinations are won internally by the first internal lottery, and the second If the internal lottery is lost, seven winning combinations will win. Also, if the first internal lottery is lost and the second internal lottery wins an internal winning combination of 8 + 9 winning combinations + 15 winning combinations, 8 winning combinations will win.

  In a three-card game, there may be a case where a seven-piece combination or a single-piece combination B is simultaneously won in combination with an internal winning combination of eight, nine, and fifteen. In this case, as in the case where the first internal lottery is lost, if only 8 winning combinations are won, there is a risk that the player will be dissatisfied. Similarly, there may be a case where a 7-piece combination or a 1-piece combination B is simultaneously won in combination with the internal winning combination of 1-sheet combination A + 2-sheet combination + 8-sheet combination. In this case, as in the case where the first internal lottery is lost, if only one winning combination A is won, there is a possibility that the player will be dissatisfied. Therefore, in the slot machine 1 of this example, when the 7 internal winning combination is won by the first internal lottery in combination with the internal winning of the 8 internal winning combination + the 9 positive winning combination + the 15 internal winning combination in the second internal lottery, If a single winning combination B wins simultaneously, nine winning combinations will win. According to such a setting, the dissatisfaction on the player side as described above can be suppressed.

  In the slot machine 1, the degree of expectation for the simultaneous winning of bonus combinations differs depending on the type of the small combination won. For example, a winning combination of a single winning combination A in a two-loading game is generated according to an internal winning of 1 winning combination A + 2 winning combination + 8 winning combination, and the simultaneous winning probability of bonus winning A at that time is 30%. Also, for example, when a single winning combination B is won in a single-loading game, there is a possibility that the bonus winning combination B is won simultaneously with a probability of 40%.

  Furthermore, since the second internal lottery and the first internal lottery are executed at the same time in the three-player game, the bonus combination A and the bonus combination B may be won simultaneously. For example, in the case of a two-piece winning in a three-card insertion game, an internal winning of a single winning combination A + 2 winning + 8 winning in the second internal lottery and an internal winning of a single winning B in the first internal lottery are simultaneously performed. Occurs when it occurs. At that time, the probability that the bonus combination A and the bonus combination B are won simultaneously is 12% and the probability is high.

  On the other hand, in the slot machine 1, eight winning combinations are won internally in the first internal lottery under the three-player game, and when the second internal lottery is lost, eight winning combinations are won, Even if one winning combination is won internally and 7 winning combinations are won internally in the second internal lottery, 8 winning combinations will also win. With such a setting, complex game play is realized, and it becomes difficult to judge the expectation level for the simultaneous winning of the bonus combination corresponding to the winning of 8 combinations, and the interest of the game is improved.

  The slot machine 1 configured as described above is a slot machine capable of selecting the number of game media inserted, and has an excellent characteristic that improves the fun of the game by realizing a new game by selecting the number of games inserted. It is a slot machine.

Instead of this example, it is normally possible to execute only one of the two-card insertion game and the one-card insertion game, and to execute the three-card insertion game only within a specific period.
As a trigger for starting a specific period, an internal winning of a predetermined starting role, a stop display of a predetermined starting symbol, the end of a bonus state, a lottery whether or not to start a specific period every game or periodically Winning etc. can be set.
On the other hand, as a trigger for the end of the specific period, the internal winning of the predetermined end role, the stop display of the predetermined end symbol, the winning in the lottery whether or not to end the specific period every game or periodically, the predetermined The progress of the number of games can be set.

  In addition, this example is an example in which the first internal lottery and the second internal lottery are executed in the three-card insertion game. In addition to the three-player game in which the first internal lottery and the second internal lottery are executed, a third internal lottery in which at least one of the lottery probabilities is different from the first internal lottery and the second internal lottery is executed. A three-game game may be set. Furthermore, one of a three-card insertion game in which the first internal lottery and the second internal lottery are executed, and a three-card insertion game in which the third internal lottery is executed are selected according to the player's preference. It may be executed automatically, or may be selected and executed by lottery.

  In addition, when the replay role is won in the three-card insertion game in which the first internal lottery and the second internal lottery are executed, the internal lottery in which the replay role is won internally among the first internal lottery and the second internal lottery It is preferable to set a replay game in which a predetermined number of medals corresponding to are automatically inserted and the same type of internal lottery is executed. For example, when a replay role that has been won internally in the first internal lottery wins, a replay game in which one medal, which is a specified number corresponding to the first internal lottery, is automatically inserted and the first internal lottery is executed It is good to set. In addition, when a replay role that is won internally in both the first internal lottery and the second internal lottery wins, a replay game in which three medals are automatically inserted and the first internal lottery and the second internal lottery are executed. It is good to set.

  In this example, if the winning combination of 8 + 9 + 15 in the 2nd internal lottery and 1B in the 1st internal lottery is won, the 9th winning combination will always be won. This is an example. Instead of this, it may be set such that, for example, a winning combination of 8 sheets is won in accordance with the stop timing or stop operation order.
