Description

Slot machine

  The present invention relates to a slot machine that notifies a player that a winning combination is possible.

2. Description of the Related Art Conventionally, there are known slot machines that notify a player that a winning combination is possible by various methods. This can be achieved by giving the player various effects while appropriately incorporating the case of non-winning when a special role for shifting to a game advantageous to the player, such as a special role or a small role or replay is selected. This is to notify that there is a possibility of winning a role.
As this production, for example, it is first known that production lamps provided in the slot machine are lit in a specific pattern or a specific sound is output from a speaker.
Secondly, depending on the combination of symbols when the reels are stopped, for example, a combination of symbols that means that a special role can be won is set in advance, and these symbol combinations appear during the game. It is known.

  Note that a slot machine is known that can change whether or not to be notified when a winning combination is made by an operation switch or the like (Japanese Patent Laid-Open No. 10-33750). According to this slot machine, it is possible to flexibly cope with a business form in which a winning combination is notified and a business form in which a combination is not notified.

  In the above-described conventional slot machine, if the fact that the special role can be won is notified by various methods, the fact can be known, so that it is easier to understand especially for beginners. However, for advanced users, even if no notification is given, it may be possible to determine whether or not a special role has been won by the reel stop control when the stop switch is operated, etc. Furthermore, there may be a case where the presence or absence of a winning combination has already been known due to the performance performed during the previous game. Thus, even if the player knows whether or not the winning combination has been made, the player has no sense of expectation or tension, so such a notification does not make sense. There is.

  Furthermore, when notifying that there is a possibility of winning a winning combination after the reels are stopped, the reception of operations such as insertion of medals for shifting to the next game is stopped while the effect is output. Therefore, there is a problem that the player needs to wait until the production is finished, and cannot smoothly shift to the next game.

In addition, as in the slot machine described in the above-mentioned Japanese Patent Laid-Open No. 10-33750, the method that can change whether or not the winning combination is notified corresponds to a sales form such as a hall in which the slot machine is installed. Although there is a problem, there is a problem that the player is not always switched to the preferred one.
Note that the technology described in this publication changes whether or not to notify that the winning combination is won as a result of the lottery. However, this technique is used, including the case of non-winning. It may be possible to change whether or not to notify that there is a possibility of winning.

However, various effects such as lighting of lamps and sound output are performed, and it is the best part of the game to predict the winning of the role to some extent by comprehensively judging those effects, The same applies to advanced players.
Therefore, if the technology disclosed in the above publication is used to switch to the presence / absence of the effect of having the possibility of winning the role, regardless of whether the role is won, for example, there is no effect. For this reason, there is a problem that even the advanced player as well as the beginner cannot feel the game fun.

  Therefore, the problem to be solved by the present invention is to make it possible to set the frequency of the performance to the effect that the winning combination is possible and to set the optimal performance frequency according to the player's preference and the like. .

The present invention solves the above-described problems by the following means.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an outline of control of the slot machine in the present embodiment.
The game control means 60 of the slot machine 10 is a means for comprehensively controlling the entire slot machine 10 including the progress and effects of the game of the slot machine 10. The game control means 60 includes a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and data that is captured when the CPU performs various controls. RAM and the like that are temporarily stored.

Peripheral devices such as the motor 32 described below are electrically connected to the output side (right side in the figure) of the game control means 60.
The motor 32 is for rotating the reel 31, is connected to the center of rotation of the reel 31, and is controlled by the game control means 60.

The reel 31 has a ring shape, and a reel tape on which a plurality of types of symbols (such as symbols constituting a winning combination) are attached is attached to the outer peripheral surface thereof. One reel 31 is provided with, for example, 21 symbols at equal intervals.
In the present embodiment, three reels 31 are provided in parallel. Each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from a display window (not shown) provided on the front panel of the slot machine 10. Therefore, nine symbols are arranged so that a total of nine symbols can be seen from the display window of the slot machine 10.
When the reel 31 is rotated by the motor 32, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window at a predetermined speed.

Examples of winning combinations include multiple types of special roles, multiple types of small roles, and replays.
The special role is a role that shifts from a normal game to a special game (a game that can be expected to win many medals and is advantageous to the player). Examples of the special combination include a big bonus, a regular bonus, and a single bonus.

The small combination is a combination in which a predetermined number of medals are paid out, and there are provided a plurality of types in which the number of medals paid out differs depending on the combination of symbols.
In addition, the replay is a re-playing role that allows a re-play to be performed while maintaining the number of inserted medals (the number of bets) in the game.

A combination of symbols of the reel 31 corresponding to the above various combinations is determined in advance. When all the reels 31 are stopped, if the combination of symbols stopped on the active line matches a predetermined combination of symbols of the combination, a winning combination of the combination is awarded.
For example, if the combination of symbols of the special bonus big bonus is set to “7”-“7”-“7”, each reel is placed on one of the active lines when all the reels 31 are stopped. When the symbol “7” of 31 is stopped, a big bonus is won.

Here, although not shown, for example, five effective lines are set in the portion including the display window of the front panel. This effective line is composed of three horizontal upper, middle and lower lines, and two diagonally downward and leftward directions.
The three symbols that are continuous from top to bottom of the reel 31 that can be seen from each display window are located on three effective lines in the upper, middle, and lower stages in the horizontal direction.
Also, this valid line is validated according to the number of inserted medals. If one medal is inserted, one effective line in the middle in the horizontal direction is activated. If it is two, three effective lines in the horizontal direction are activated. If three, all five effective lines are activated. The

The lamps 33 are effects lamps for the slot machine 10 and are lit in a predetermined pattern when a predetermined condition is satisfied. The slot machine 10 is provided with a plurality of lamps for performing various effects during the game. The lamp 33 shown in FIG. 1 is one of the lamps.
The speaker 34 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
The image display device 35 includes a liquid crystal image display device, a dot display, and the like, and displays various effect images, predetermined information, and the like during the game.

Further, peripheral devices shown below are electrically connected to the input side (left side in the figure) of the game control means 60.
The start switch 41 is a switch operated when the player starts the rotation of the reel 31.
Three stop switches 42 are provided independently for each reel 31, and are operated when the player stops the rotation of each reel 31.

  In a normal game, the player inserts a medal from a medal insertion slot (not shown) or operates a bet switch (not shown) to enable an effective line and turns on the start switch 41. Thereby, all the reels 31 are started. Then, the player presses each stop switch 42 to stop the rotation of each reel 31. When all of the reels 31 are stopped, if the combination of symbols on the reels 31 on the active line matches a predetermined combination of symbols of a certain combination, the winning combination is awarded, and medals are paid out according to the winning combination. Is done.

  The combination winning effect frequency setting means 43 is for setting the frequency of performing the effect indicating that there is a possibility of winning a combination. In the present embodiment, the winning effect presentation frequency setting means 43 is formed in a switch shape and is switchable in three stages. Further, in the present embodiment, the slot machine 10 is provided on the front surface portion together with the above-described start switch 41 and stop switch 42 so that the player can operate it.

  The player can set the effect frequency by operating the winning effect effect frequency setting means 43 according to his / her preference. If the three-stage switching of the winning effect production frequency setting means 43 is, for example, “A”, “B”, and “C”, “A” is set to have the largest production frequency, and “B” is normal. The production frequency is set, and “C” is set so that the production frequency is minimized.

In addition, a setting reception period for receiving the setting of the winning effect production frequency setting means 43 is provided. This setting reception period is when a game is not being performed (during standby). When the setting by the winning effect production frequency setting means 43 is performed during the game, the setting is controlled so as not to be accepted in the game.
Here, the game in progress may be, for example, from when the start switch 41 is turned on to when all the reels 31 are stopped, or when a medal is inserted from the medal insertion slot or the bet switch is turned on. The time from when the game medal is inserted to when all the reels 31 are stopped may be used.

  In addition, when the setting is performed by the winning effect frequency setting means 43 during the game or during a period other than the setting reception period, the setting may be invalidated after the next game, or the setting may be set in the next game. It may be enabled.

The game control means 60 includes the following means. The following means in the present embodiment are examples, and the game control means 60 is not limited to the means shown in the present embodiment.
(Role lottery means)
The role lottery means 61 performs lottery of a role (special role, small role, replay, etc.). The role lottery means 61 is based on, for example, a random number generator for hard lottery (hard random number, etc.), a random number extractor for extracting a random number generated by the random number generator, and a random value extracted by the random number extractor. Determination means for determining whether or not a winning combination has been won and a winning combination.

  The random number generation means of the role lottery means 61 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number extracting means extracts the random number generated by the random number generating means at a predetermined time, in this embodiment, when the start switch 41 is turned on by the player. The determination unit determines the combination corresponding to the area to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with the lottery table. For example, when the extracted random number value belongs to the special combination winning area, it is determined that the special combination is won, and when it belongs to the non-winning area, it is determined to be non-winning.

(Role selection method for role selection)
When the turn-off effect lottery means 62 detects that the start switch 41 is turned on every time the game is started, based on the lottery result of the part in the role lottery means 61, the effect contents Is selected by lottery.
Here, the winning effect production lottery means 62 uses the same random number generation means, random number extraction means, and determination means as those explained in the role lottery means 61. In the present embodiment, for each game, after the lottery of the role lottery means 61, the random number generated by the random number generation means in the winning effect lottery means 62 is extracted, and the random number value is selected as the selected lottery probability table 63. The contents of production are determined by collating. The random number is not limited to a hard random number but may be a soft random number, for example.

(Lottery probability table)
The lottery probability table 63 is used for the lottery of the effect by the role winning effect lottery means 62. In the present embodiment, the lottery probability table 63 has three types: a first lottery probability table 63a, a second lottery probability table 63b, and a third lottery probability table 63c. Each of these lottery probability tables 63 is set so that the probabilities determined to perform the effect of having the winning possibility of a combination (in this embodiment, a special combination) are different.

Each lottery probability table 63 has an area corresponding to the random number extracted by the random number extracting means of the winning effect producing lottery means 62, and the effect pattern is defined for each area.
For example, if the extracted random value is in the range of 0 to 65535, the effect pattern 1 is determined when the random value is 0 to 1024, and the effect pattern 2 is determined when the random value is 1025 to 1280. The effect patterns include a pattern that gives an effect indicating that a special role can be won and a pattern that is not executed.

The first lottery probability table 63a is set to have the highest probability of selecting an effect pattern that produces an effect indicating that a special role can be won among the three lottery probability tables 63. In addition, the third lottery probability table 63c is set to have the lowest probability that an effect pattern that produces an effect indicating that a special role can be won is selected from the three lottery probability tables 63.
Further, in each lottery probability table 63, an effect pattern that produces an effect indicating that a special role is won is selected depending on whether or not a special role is won in the lottery of the role by the role lottery means 61. The probabilities are set differently.

For example, in a game in which a special role is not won in the role lottery means 61, the probability that an effect pattern that provides the possibility of winning the special role is selected in the first lottery probability table 63a. It is set to 15%, 10% in the second lottery probability table 63b, and 5% in the third lottery probability table 63c.
In the game in which a special role is won in the role lottery means 61, the probability that an effect pattern that provides the possibility of winning the special role is selected in the first lottery probability table 63a. It is set to 60%, 30% in the second lottery probability table 63b, and 10% in the third lottery probability table 63c.

(Lottery probability table selection means)
The lottery probability table selecting unit 64 selects any one of the first lottery probability table 63a, the second lottery probability table 63b, and the third lottery probability table 63c as the lottery probability table 63 used for the lottery of the winning effect production lottery unit 62. Is.
In the present embodiment, one of the lottery probability tables 63 is selected based on the setting of the winning effect production frequency setting means 43.

  For example, when “A” in which the effect frequency is the highest is set by the role winning effect frequency setting means 43, the effect that there is a possibility of winning the special role in the three lottery probability tables 63 is performed. The first lottery probability table 63a set with the highest probability to be determined is selected. Further, when the production frequency is set to “B” that is medium, the second lottery probability table 63b is selected. Furthermore, when “C” is set at which the production frequency is the lowest, the probability that the production is determined to have the possibility of winning the special role in the three lottery probability tables 63 is set to the lowest. The third lottery probability table 63c thus selected is selected.

(Reel stop control means)
The reel stop control means 65 determines a predetermined stop position, which will be described later, from the game state (normal game state, special game state, etc.), the lottery result of the role lottery means 61, the timing when the stop switch 42 is turned on, and the like. The stop position of the reel 31 is determined with reference to the determination table 66, and the reel 31 is controlled to stop at the determined position. When the stop position of the reel 31 is determined by the stop position determination table 66, the reel stop control means 65 controls the drive of the motor 32 so that the reel 31 stops at the determined position.

  Here, when any combination is won by the combination lottery means 61, the combination of the symbols of the reels 31 corresponding to the winning combination is controlled so as to stop on the active line as much as possible. In addition, when the winning lottery means 61 does not win the lottery, the reel 31 is controlled to stop so that a combination of symbols of a certain combination does not stop on the active line.

(Stop position determination table)
In the present embodiment, the stop position determination table 66 has three types: a first stop position determination table 66a, a second stop position determination table 66b, and a third stop position determination table 66c. Each of these stop position determination tables 66 has a different probability of causing a combination of symbols that means that a special role can be won. In the present embodiment, the first stop position determination table 66a is set to have the highest probability of appearance of a combination of symbols that means that there is a possibility of winning a special role among the three stop position determination tables 66. 3 The stop position determination table 66c is set to the lowest.

Here, as a combination of symbols meaning that a special role can be won, first, it means that a special role can be expected to some extent, but it means that a special role is not necessarily won. There is a “chance eye” that is a combination of symbols.
Secondly, there is a combination of symbols that means that the special role is won, that is, “reach eyes” that means that the special role is won.

Each stop position determination table 66 is determined so that reach eyes or chance eyes appear on the basis of whether or not a special combination is won in the combination lottery means 61.
In a game in which a special role is not won, each stop position determination table 66 may cause a chance eye to appear, but does not cause a reach eye to appear.
On the other hand, in a game that has been won as a special role, each stop position determination table 66 may cause reach eyes in addition to chance eyes.

And in the game which is not elected as a special role, the 1st stop position determination table 66a is determined so that the appearance probability of a chance eye may become the highest among the three stop position determination tables 66. Further, the third stop position determination table 66c is determined so that the appearance probability of the chance eye is the lowest.
Similarly, in the game won for the special role, the first stop position determination table 66a is determined so that the appearance probability of the chance or reach eye is the highest among the three stop position determination tables 66. The third stop position determination table 66c is determined so that the chance probability or reach eye appearance probability is the lowest.

  Furthermore, in the game at the time of winning the small role or replay, in any stop position determination table 66, the winning combination will be awarded as much as possible, that is, the combination of symbols of the winning role is as effective as possible. The stop control of the reel 31 is determined so as to stop at the line.

(Stop position determination table selection means)
The stop position determination table selection means 67 corresponds to the stop control selection means in the present invention. As the stop position determination table 66 used in the reel stop control means 65, a first stop position determination table 66a and a second stop position determination are used. Either the table 66b or the third stop position determination table 66c is selected.
In the present embodiment, one of the stop position determination tables 66 is selected based on the setting of the winning effect presentation frequency setting means 43.

  For example, when the role winning effect frequency setting means 43 is set to “A” where the effect frequency is the highest, the symbol indicating that there is a possibility of winning a special role in the three stop position determination tables 66. The first stop position determination table 66a determined so that the combination appearance probability is the highest is selected. In addition, when the production frequency is set to “B” that is medium, the second stop position determination table 66b is selected. Furthermore, when “C” is set at which the production frequency is the lowest, the appearance probability of the combination of symbols that means that the special position can be won among the three stop position determination tables 66 is the lowest. The third stop position determination table 66c determined as described above is selected.

(Production output control means)
The effect output control means 68 controls the output of the effects according to the effect pattern selected by the above-described winning effect effect lottery means 62. Peripheral devices that output this effect include a lamp 33, a speaker 34, and an image display device 35.

  In each effect pattern, the contents of the effect when the effect indicating the possibility of winning the special role is performed are defined. For example, there is provided an effect pattern data table that defines the effect contents for each effect pattern. Then, when the effect pattern is selected by the winning effect effect lottery means 62, the effect contents determined for the determined effect pattern are output according to the effect pattern data table. In each effect pattern, for example, a lighting pattern of the lamp 33, a sound output pattern from the speaker 34, an output image pattern by the image display device 35, an output time thereof, and the like are defined.

Although not shown, the game control means 60 is provided with a winning determination means, a payout means, etc. in addition to the above-described means.
The winning determination means determines whether or not the combination of symbols stopped on any one of the active lines matches the predetermined combination of symbols for any combination when the reel 31 is stopped. The winning determination means determines the symbol on the active line by detecting, for example, the angle when the motor 32 is stopped, the number of steps, and the like, and based on this, determines the presence / absence of a winning combination.

  The payout means determines a predetermined number of coins according to the winning combination when it is determined by the winning determination means that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols of any combination. A medal is paid out to the player or credits are added. When a replay is won, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

Next, the flow of processing in the present embodiment will be described based on a flowchart. 2 and 3 are flowcharts for explaining the flow of processing in the present embodiment. FIG. 3 is a flowchart following FIG.
In the present flowchart, a case where an effect is performed after all the reels 31 are stopped will be described as an example of the effect that the special role is likely to be won.

  First, in step S1 of FIG. 2, the game control means 60 continues to detect whether or not the start switch 41 is turned on by the player. When it is detected that the start switch 41 is turned on, the reel 31 is started, and the process proceeds to step S2, where the lottery probability table selection means 64 and the stop position determination table selection means 66 are set in the winning selection effect frequency setting means 43 (effect frequency). ).

  In the next step S <b> 3, the lottery probability table selecting unit 64 selects the lottery probability table 63 according to the setting of the winning effect presentation frequency setting unit 43. In other words, the lottery probability table selecting means 64 uses the first lottery probability table 63a when the setting of the winning effect presentation frequency setting means 43 is “A”, and the second lottery probability table 63b when the setting is “B”. When it is “C”, the third lottery probability table 63c is selected.

In the next step S4, the stop position determination table selection means 67 selects the stop position determination table 66 according to the setting of the winning effect presentation frequency setting means 43. That is, the stop position determination table selection unit 67 uses the first stop position determination table 66a when the setting of the winning effect presentation frequency setting unit 43 is “A”, and the second stop position determination table when the setting is “B”. If 66b is “C”, the third stop position determination table 66c is selected.
Next, proceeding to step S5, the combination lottery means 61 performs a combination lottery. In the next step S6, the winning combination effect lottery means 62 uses the lottery probability table 63 selected in step S3 to perform a lottery to determine whether or not to perform an effect indicating that the special combination is likely to be won. That is, one of the production patterns is selected by lottery.

  Next, proceeding to step S7, the game control means 60 continues to detect whether or not the stop switch 42 is turned on by the player. When it is detected that the stop switch 42 is turned on, in the next step S8, the stop position of the reel 31 is determined based on whether or not a winning combination has been won, the gaming state, etc., using the stop position determination table 66 selected in step S4. Is determined. Next, the process proceeds to step S9 in FIG. 3, and it is detected whether or not all the reels 31 are stopped. If it is determined that all the reels 31 are not stopped, the process returns to step S7 in FIG. On the other hand, when it is determined in step S9 that all the reels 31 are stopped, the process proceeds to step S10.

In step S10, it is determined whether or not the effect pattern selected in step S6 is an effect pattern that provides an effect indicating that the special role is likely to be won after all the reels 31 are stopped. If it is determined that an effect pattern for effecting is selected, the process proceeds to step S11, and after the effect is output according to the selected effect pattern, the process proceeds to step S12. On the other hand, if it is determined in step S10 that an effect pattern that does not produce an effect is selected, the process proceeds to step S12 without performing the process of step S11.
In step S12, the winning determination means determines the presence / absence of a winning from the combination of symbols stopped on the active line, and if there is a winning, performs a process such as payout according to the winning combination. And the process by this flowchart is complete | finished.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications such as the following are possible.
