Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine for notifying a player that a role can be won.

[0002]

2. Description of the Related Art Heretofore, there has been known a slot machine for notifying a player of the possibility of winning a role by various methods. This is done by giving the player various effects, such as a special role for shifting to a game that is advantageous to the player, a small role or a replay, and appropriately taking into account the non-winning case. This is to notify that the role can be won. As the effect, for example, first, it is known that effect lamps provided in a slot machine are turned on in a specific pattern or a specific sound is output from a speaker. Also the second
According to the combination of symbols when the reels are stopped, for example, it is known that a combination of symbols that means that a special combination can be won is set in advance, and that the combination of these symbols appears during a game. Have been.

[0003] A slot machine is known in which, when a role is won, whether or not to notify the effect can be changed by an operation switch or the like (Japanese Patent Laid-Open No. 10-33).
750). According to this slot machine, it is possible to flexibly cope with a business mode in which a winning of a role is notified and a business mode in which a role is not notified.

[0004]

In the above-mentioned conventional slot machine, if the possibility of winning a special role is notified in various ways, the fact can be known, and especially for beginners. , It is easier to understand. However, for advanced users, even if the notification is not performed, it may be possible to determine whether or not the special role has been won by the reel stop control when the stop switch is operated, or the like. Furthermore, there may be a case where a player has already known whether or not a role has been won, based on an effect performed during a previous game. As described above, even if the notification is made when the player knows whether or not the role has been won, the player does not have any sense of expectation or tension, and such notification does not make sense. There is.

[0005] Further, if the user is notified of the possibility of winning a winning combination after the reels are stopped, the reception of operations such as the insertion of medals for shifting to the next game is stopped while the effect is being output. . Therefore, there is a problem that the player needs to wait until the effect ends, and cannot smoothly shift to the next game.

[0006] Further, as in the slot machine described in the above-mentioned Japanese Patent Application Laid-Open No. 10-33750, a method of changing whether or not to notify the winning of a role can be changed by operating a hall or the like where the slot machine is installed. However, there is a problem that the player is not always switched to a preferred one. Note that the technology described in this publication changes whether or not to notify on the condition that a role has been won as a result of a lottery. It is conceivable to be able to change whether or not to notify that the player has the possibility of winning.

[0007] However, various effects such as lighting of lamps and sound output are performed in various ways, and it is a real pleasure of the game to predict the winning of the role to some extent by comprehensively judging the effects. This is the same for advanced users. Therefore, irrespective of the presence or absence of a winning combination, if there is switching to the presence or absence of the effect of having the possibility of winning the role using the technology of the above-mentioned publication, for example, there will be no production at all. For this reason, there is a problem that not only beginners but also advanced users cannot enjoy the fun of the game.

[0008] Therefore, an object of the present invention is to make it possible to set an effect frequency indicating that there is a possibility of winning a role, and to set an optimum effect frequency in accordance with a player's preference or the like. That is.

[0009]

The present invention solves the above-mentioned problems by the following means. (Claim 1) According to the invention of claim 1, a role lottery means for performing a lottery of a role, and whether or not to perform an effect indicating that there is a possibility of winning a role based on a result of a lottery of a role by the role lottery means. And a plurality of lottery probability tables that are used in the lottery by the role-winning effect lottery means and have different probabilities of being determined to perform, and that there is a possibility of winning the role. A role selection effect frequency setting means for setting the frequency of performing the effect, and a lottery probability table selection means for selecting the lottery probability table used in the role selection effect lottery means based on the setting of the role selection effect frequency setting means. It is characterized by having.

According to the first aspect of the present invention, the frequency of performing the effect of having the possibility of winning the role is set by the role-winning effect frequency setting means.

Are electrically connected to peripheral devices such as a motor 32 described below. The motor 32 is for rotating the reel 31, is connected to the rotation center of the reel 31, and is controlled by the game control means 60.

The reel 31 has a ring shape, and has a reel tape on which a plurality of types of symbols (eg, symbols constituting a winning combination) are printed on the outer peripheral surface thereof. 1
One reel 31 is provided with, for example, 21 symbols at equal intervals. In this embodiment, three reels 31 are provided in parallel. Further, each reel 31 is used for the slot machine 10.
Are arranged so that three vertically continuous patterns can be seen from a display window (not shown) provided on the front panel. Therefore, from the display window of the slot machine 10, a total of 9
It is arranged so that individual designs can be seen. Then, when the reel 31 is rotated by the motor 32, the symbol on the reel 31 is moved and displayed in the display window at a predetermined speed in the vertical direction.

The winning combinations include, for example, a plurality of special combinations, a plurality of small combinations, 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 obtain many medals and is advantageous for a 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 a plurality of types are provided in which the number of medals paid out differs depending on the combination of symbols. In addition, the replay is a replaying combination, and is a combination that enables a replaying while maintaining the number of inserted medals (the number of bets) in the game.

The combinations of the symbols on the reel 31 corresponding to the above various combinations are predetermined. Then, when all the reels 31 are stopped, if the combination of the symbols stopped on the activated line matches the combination of the symbols of the predetermined combination, the winning combination is won. For example, if the combination of the symbols of the big bonus as the special combination is set to “7” − “7” − “7”, when all the reels 31 are stopped,
When the symbol “7” of each reel 31 is stopped on any of the activated lines, a big bonus is won.

Here, although not shown, for example, five effective lines are set in a portion including the display window of the front panel. This effective line is composed of three lines in the upper, middle, and lower stages in the horizontal direction, and two lines in the diagonally downward and rightward directions. Then, the three symbols continuous from above and below the reel 31 seen from each display window are located on three effective lines in the upper, middle, and lower rows in the horizontal direction. This activated line is activated according to the number of inserted medals. When one medal is inserted, one effective line in the middle stage in the horizontal direction is activated. When two medals are inserted, all three activated lines are activated in the horizontal direction. When three medals are inserted, all five activated lines are activated. You.

The lamp 33 is used for the slot machine 10.

Further, the following peripheral devices are electrically connected to the input side (the left side in the figure) of the game control means 60. The start switch 41 indicates that the player
This is a switch operated when starting one rotation. The stop switch 42 is a switch that is arranged in parallel for each reel 31 independently and is operated by a player when the rotation of each reel 31 is stopped.

In a normal game, a player inserts medals from a medal insertion slot (not shown) or operates a bet switch (not shown) to activate an activated line, and turns on a start switch 41. . Thereby, all the reels 31 are started. Then, the player stops the rotation of each reel 31 by pressing each stop switch 42.
When all the reels 31 are stopped, the reels 3 on the activated line
When the combination of the first symbol matches a predetermined combination of symbols of some combination, the combination is won, and medals are paid out according to the established combination.

The winning combination effect frequency setting means 43 is for setting the frequency of performing an effect indicating that there is a possibility of winning a winning combination. In this embodiment, the role winning effect frequency setting means 4
Reference numeral 3 is formed in a switch shape, and is formed to be switchable in three stages. Further, in the present embodiment, the start switch 41 and the stop switch 42 are provided on the front surface of the slot machine 10, so that the player can operate the slot machine 10.

The player can operate the winning combination effect frequency setting means 43 to set the frequency of the effect according to his / her preference. When the three-stage switching of the role winning effect frequency setting means 43 is, for example, “A”, “B”, and “C”,
"A" is set to have the most directing frequency,
“B” is set to the normal effect frequency, and “C” is set to minimize the effect frequency.

A setting receiving period for receiving the setting of the role winning effect frequency setting means 43 is provided. This setting reception period is a time when the game is not performed (at the time of standby). Role winning effect production frequency setting means 43 during the game progress
Is set 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,
Alternatively, a period from when a medal is inserted through the medal insertion slot or when a bet switch is turned on and a game medal is inserted and when all the reels 31 are stopped may be used.

When a setting is made by the winning combination effect frequency setting means 43 during the progress of the game or during a period other than the setting reception period, the setting may be invalidated after the next game.
Alternatively, the setting may be made effective in the next game.

The game control means 60 includes the following means. The following means in the present embodiment are exemplifications, and the game control means 60 is not limited to the means shown in the present embodiment. (Position Lottery Means) The role lottery means 61 performs lottery of a role (special role, small role, replay, etc.). Role lottery means 6
1 is, for example, random number generating means (hard random number or the like) for winning lottery, random number extracting means for extracting a random number generated by the random number generating means, and winning of the hand based on the random number value extracted by the random number extracting means. Determining means for determining the presence / absence of a winning combination and the winning combination.

The random number generation means of the combination lottery means 61 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal system). 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 determining means determines the combination corresponding to the area to which the random value belongs by comparing the random number value extracted by the random number extracting means with the lottery table. For example, if the extracted random number value belongs to the special combination winning area, it is determined that the special combination has been won, and if it belongs to the non-winning area, it is determined that it has not been won.

(Role Winning Effect Draw Lottery Means) The role hit effect draw lottery means 62 has a start switch 41 each time a game is started.
When it is detected that the game is turned on, the effect content is selected by lottery using a lottery probability table 63 described later based on the lottery result of the role in the lottery means 61. Here, the winning combination effect lottery means 62 uses the same random number generating means, random number extracting means, and judging means as those described in the role lottery means 61. In the present embodiment, for each game, after the lottery of the role by the role lottery means 61, the role winning effect lottery means 62
The effect contents are determined by extracting the random number generated by the random number generating means in the inside and comparing the random number value with the selected lottery probability table 63. The random number is not limited to a hard random number, but may be a soft random number.

(Lottery Probability Table) Lottery Probability Table 6
3 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. These lottery probability tables 63 are set so that the probabilities of determining that there is a winning possibility of a winning combination (a special winning in the present embodiment) are determined.

Each lottery probability table 63 has an area corresponding to a random number value extracted by the random number extracting means of the role-winning effect lottery means 62.
The effect pattern is determined. For example, if the random number value to be extracted is in the range of 0 to 65535,
In the case of 1024, effect pattern 1, 1025-1280
In the case of, the effect pattern 2 is determined. The effect patterns include a pattern for performing an effect indicating that there is a possibility of winning a special role, and a pattern for not performing the effect.

Then, the first lottery probability table 63a is
In the three lottery probability tables 63, the probability of selecting an effect pattern for performing an effect indicating that there is a possibility of winning a special role is set to be the highest. In the third lottery probability table 63c, among the three lottery probability tables 63, the probability that an effect pattern for performing the effect of having the possibility of winning the special role is selected is set to be the lowest. Furthermore, each lottery probability table 63 indicates whether or not a special role has been won in the lottery of the role by the role lottery means 61.
It is set so that the probability of selecting an effect pattern for performing an effect indicating that there is a possibility of winning a special role is different.

For example, in a game in which the special lottery is not won in the lottery of the role by the lottery means 61, the probability of selecting an effect pattern for effecting the possibility of winning the special role is the first lottery probability. 15% is set in the table 63a, 10% in the second lottery probability table 63b, and 5% in the third lottery probability table 63c. In a game in which the special lottery is won in the lottery of the role by the lottery lottery means 61, the probability that the effect pattern for performing the effect of having the possibility of winning the special role is selected is determined by the first lottery probability table 63a. 60%, 30% in the second lottery probability table 63b, and 1% in the third lottery probability table 63c.
0%.

(Lottery Probability Table Selection Means) The lottery probability table selection means 64 is a first lottery probability table 63a, a second lottery probability table 63b, or a third lottery probability table 63 used as a lottery probability table 63 used for the lottery of the role-winning effect lottery means 62. This selects one of the lottery probability tables 63c. In the present embodiment, one of the lottery probability tables 63 is selected based on the setting of the role winning effect frequency setting means 43.

For example, when the role selection effect frequency setting means 43 is set to “A”, which is the most frequent effect frequency,
From the three lottery probability tables 63, the first lottery probability table 63a in which the probability of deciding to perform an effect indicating the possibility of winning a special combination is set to the highest is selected.
In addition, when the effect frequency is set to “B” which is medium, the second lottery probability table 63b is selected. Furthermore, when the effect frequency is set to “C”, which is the least frequently produced, the probability of being determined to perform an effect indicating that there is a possibility of winning a special role is set to the lowest among the three lottery probability tables 63. The selected third lottery probability table 63c is selected.

(Reel Stop Control Means) The reel stop control means 65 is in a game state (normal game state, special game state, etc.).
And the lottery result of the role lottery means 61 and the stop switch 4
The stop position of the reel 31 is determined with reference to a predetermined stop position determination table 66, which will be described later, based on the timing when the 2 is turned on, and the stop of the reel 31 is controlled at the determined position. . The reel stop control means 65 controls the reel 31 based on the stop position determination table 66.
Is determined, the drive of the motor 32 is controlled to control the reel 31 to stop at the determined position.

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

(Stop Position Determination Table) In this embodiment, the stop position determination table 66 includes a first stop position determination table 66a, a second stop position determination table 66b, and a third stop position determination table 66b.
There are three types of stop position determination tables 66c. Each of the stop position determination tables 66 has a different probability of appearing a combination of symbols that means that there is a possibility of winning a special combination. In the present embodiment, in the first stop position determination table 66a, among the three stop position determination tables 66, the appearance probability of a symbol combination that indicates that there is a possibility of winning a special combination is set to be the highest, 3
The stop position determination table 66c is set at the lowest position.

Here, as a combination of symbols which means that the special role can be won, first, the special role can be expected to be elected to some extent, but the special role is not always elected. There is a “chance eye” which is a combination of symbols that means Secondly, there is a combination of symbols that means that the special role has been won, that is, a “reach eye” that means that the special role has been won.

Each stop position determination table 66 is set so that a reach eye or a chance eye will appear based on whether or not a special combination has been won in the lottery selection by the combination lottery means 61. In a game that has not been won as a special combination, each stop position determination table 66 may cause a chance to appear, but does not cause a reach to appear. On the other hand, in a game that has been won as a special combination, each stop position determination table 66 may display a reach eye in addition to a chance eye.

In a game in which a special combination has not been won, the first stop position determination table 66a is set so that the probability of appearance of a chance among the three stop position determination tables 66 is the highest. In addition, the third stop position determination table 66c is set so that the probability of appearance of a chance is the lowest. Similarly, in a game that has been won as a special combination, the first stop position determination table 66a is determined so that the probability of appearance of a chance or reach among the three stop position determination tables 66 is highest. Further, the third stop position determination table 66c is set such that the probability of appearance of the chance eye or the reach eye is the lowest.

Further, in the game at the time of winning the small role or the replay, regardless of the stop position determination table 66,
The stop control of the reels 31 is determined so that these winning combinations win as much as possible, that is, the combinations of the symbols of the winning combinations stop on the active line as much as possible.

(Stop position determining table selecting means) The stop position determining table selecting means 67 corresponds to the stop control selecting means in the present invention. One of the stop position determination table 66a, the second stop position determination table 66b, and 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 combination effect frequency setting means 43.

For example, when the role-winning effect frequency setting means 43 is set to “A”, which is the most frequent effect frequency,
From among the three stop position determination tables 66, the first stop position determination table 66a determined so that the appearance probability of the symbol combination that indicates the possibility of winning the special combination is the highest is selected. In addition, when the effect frequency is set to “B” which is medium, the second stop position determination table 66b is selected. Furthermore, when the effect frequency is set to “C” which is the least effective, the appearance probability of the symbol combination that means that the special role can be won in the three stop position determination tables 66 is the lowest. The third stop position determination table 66c thus determined is selected.

(Production output control means) Production output control means 6
Numeral 8 controls the output of the effect in accordance with the effect pattern selected by the above-mentioned role selection effect lottery means 62. Peripheral devices that output this effect include lamp 3
3, a speaker 34, and an image display device 35.

In each effect pattern, the effect contents when an effect to the effect that there is a possibility of winning a special role are determined. For example, an effect pattern data table in which effect contents are determined for each effect pattern is provided. And
When an effect pattern is selected by the role-winning effect lottery means 62, the effect contents determined in the determined effect pattern are output according to the effect pattern data table. For 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 prize discriminating means, a payout means and the like in addition to the above-described means. The winning determination means determines whether or not the combination of symbols stopped on any of the activated lines when the reel 31 is stopped matches a predetermined combination of symbols of any combination. The winning determination means determines the symbol on the activated line by detecting, for example, the angle when the motor 32 is stopped, the number of steps, and the like, and determines the presence or absence of a winning combination based on this.

Further, the payout means, according to the winning combination, when it is determined by the winning determination means that the combination of the symbols stopped on the activated line when the reel 31 is stopped matches the combination of the symbols of any of the combinations. A predetermined number of medals are paid out to the player, or processing such as credit addition is performed. At the time of winning a replay, 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 this embodiment will be described based on a flowchart. 2 and 3
5 is a flowchart illustrating the flow of a process according to the present embodiment. FIG. 3 is a flowchart following FIG. In this flowchart, as an effect indicating that there is a possibility of winning a special combination, a case where an effect is performed after stopping all the reels 31 will be described as an example.

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. Start switch 4
1 is detected, the reel 31 is started, and the process proceeds to step S2, where the lottery probability table selecting means 6
4 and the stop position determination table selection means 66 determine the setting (production frequency) of the winning combination effect frequency setting means 43.

In the next step S 3, the lottery probability table selecting means 64 selects the lottery probability table 63 in accordance with the setting of the winning combination effect frequency setting means 43. That is, the lottery probability table selecting means 64 displays the first lottery probability table 63a when the setting of the role-winning effect frequency setting means 43 is “A”, the second lottery probability table 63b when the setting is “B”, If "C", the third lottery probability table 6
3c, respectively.

In the next step S4, the stop position determination table selecting means 67 selects the stop position determination table 66 in accordance with the setting of the winning combination effect frequency setting means 43. In other words, the stop position determination table selection means 67 sets the first stop position determination table 66a when the setting of the winning combination effect frequency setting means 43 is “A”, and sets the second stop position determination table 66a when the setting is “B”.
When the stop position determination table 66b is "C", the third stop position determination table 66c is selected.
Next, the process proceeds to step S5, and the combination lottery means 61 performs lottery selection. In the next step S6, the role winning effect lottery means 6
2 performs a lottery using the lottery probability table 63 selected in step S3 to determine whether or not to perform an effect indicating that there is a possibility of winning a special combination. That is, one of the effect patterns is selected by lottery.

May be provided separately from the combination winning effect frequency setting means 43 for setting the appearance frequency of.

(4) In this embodiment, the player-winning effect frequency setting means 43 can be operated by the player.
May be set only at the gaming store where the slot machine 10 is installed, and may not be set by the player. Further, instead of providing the winning and winning effect frequency setting means 43 for each slot machine 10, the winning and winning effect frequency setting means 43 for all slot machines 10 may be provided collectively in a control management room or the like of a game store. good.

(5) In this embodiment, a plurality of stop position determination tables 66 are provided, one of the stop position determination tables 66 is selected, and the stop position of the reel 31 is determined using the stop position determination table 66. I made it. But,
The stop position of the reel 31 may be determined without using the stop position determination table 66. For example, when the stop switch 42 is operated, it is also possible to use a stop control that searches for a stoppable position and determines an appropriate stop position within the range of the stoppable position. In this case, a plurality of stop controls having different probabilities of appearing a combination of symbols indicating that there is a possibility of winning a special role are provided, and the stop control corresponding to the setting of the role winning effect frequency setting means 43 is selected. Just do it.
