Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slot machine having a plurality of reels for variably displaying a plurality of types of symbols necessary for a game, and more particularly to a gaming machine that performs a game effect using the reels.
[0002]
[Prior art]
The conventional slot machine has three reels for variably displaying a plurality of types of symbols necessary for a game, a start switch for starting rotation of all reels at the same time on condition that a game medal is inserted, A stop switch for individually stopping the rotation of the reel, and a hopper for paying out a game medal as a prize when a combination of symbols when the reel stops constitute a predetermined winning mode .
[0003]
In such a conventional slot machine, when a player operates a start switch after a game start condition is set, a plurality of reels rotate and a plurality of symbols drawn on the surface of the reel move at high speed. When the player operates a stop switch corresponding to each reel, the rotation of each reel is stopped, and a plurality of symbols drawn on the surface of the reel are stopped and displayed.
Here, when the combination of the symbols displayed in a stopped state becomes a predetermined winning mode, a game medal as a prize is paid out by the hopper. In addition, a special game (for example, a big bonus game or a regular bonus game) advantageous to the player as compared with a general game is performed on the condition that the combination of symbols displayed in a stopped state has a predetermined special winning mode. Make it.
[0004]
In such a conventional slot machine, in order to increase the player's expectation for winning a prize, after all the reels have stopped, each reel is re-rotated so that the game can be enjoyed again.
In addition, it is determined whether or not the winning mode is configured based on the probability lottery process, and the stop switch operation by the player is inappropriate for configuring the winning mode despite the internal winning in the probability lottery process. In some cases, there is a slot machine in which the winning mode is always configured by controlling the reel stop operation.
[0005]
[Problems to be solved by the invention]
However, simply re-rotating the reel as in the conventional slot machine described above simply adds an operation that the reel is temporarily stopped with respect to the normal gaming process. It was hard to say that I could enjoy it.
In addition, if an internal winning is made in the probability lottery process, a winning mode is always configured, which will unfairly affect the profits of the amusement store, and ensure that the profits of the amusement store and the profits of the player are fair. This will defeat the purpose of the slot machine to play a special game.
[0006]
In other words, in order to achieve fairness between the game shop profit and the player profit, when it is determined whether or not the winning mode is configured based on the probability lottery process, the reel stop based on the probability lottery process is determined. In addition to the control, it is necessary to determine a payout rate, which is a profit grant rate for the player, including the timing of operating the stop switch by the player.
Furthermore, the operation of stopping the rotation of the reels can fully enjoy the fun of the game by exhibiting the gaming nature inherent in the slot machine by intervening the operation of the stop switch by the player.
[0007]
The present invention has been proposed in view of the above-described circumstances, and can ensure a balance between the profits of the game store and the player and perform a healthy game, and can play the game without impairing the original gaming characteristics of the slot machine. The object is to provide a slot machine that can fully enjoy the fun.
[0008]
[Means for Solving the Problems]

[0009]
That is, the slot machine according to the present invention includes a plurality of reels for variably displaying a plurality of types of symbols necessary for a game, a start switch for simultaneously starting rotation of all the reels, A stop switch to stop the rotation individually; When the game is started, the internal winning combination is determined by lottery, and the stop position of each reel is controlled by operating the stop switch so that the stop symbol becomes a winning mode based on the internal winning combination as much as possible. Stop control means; In a slot machine provided with a profit giving means for giving a profit to a player when a combination of symbols displayed when all the reels stop constitutes a predetermined winning mode, all the reels When reel Reel stop position storage means for storing a stop position, re-rotation means for re-rotating at least one of the plurality of reels after all the reels have stopped, and the re-rotation After the reel has been re-rotated by means reel Reel stop position stored in stop position storage means At the same position as A reel stop position return means for stopping the reel being re-rotated, and a plurality of re-rotations in which at least one of the rotation direction, the rotation speed and the rotation time is mutually changed as a reel re-rotation pattern by the re-rotation means. Re-rotation pattern storage means for storing a pattern, and re-rotation pattern selection for selecting a predetermined re-rotation pattern from a plurality of re-rotation patterns stored in the re-rotation pattern storage means by lottery using a random number And the re-rotating means performs re-rotation of the reel based on the predetermined re-rotation pattern selected by the re-rotation pattern selection means,
Multiple internal winners In correspondence with each, there is provided an effect pattern selection table representing the relationship between the re-rotation pattern and the random number value, the re-rotation pattern selection means, Internal winning role determined by lottery in the game And according to the value of the obtained random number, based on the effect pattern selection table, select the re-rotation pattern,
The plurality of re-rotation patterns have an operation of temporarily stopping in the middle, and include patterns in which symbols at the time of the temporary stop are changed from each other. The rotation pattern is It was decided by lottery in the game This is characterized in that the type of internal winning combination is suggested with a predetermined probability.
[0010]
Ma Further, the reels may be re-rotated by the re-rotating means when none of the winning modes is configured.

Is done. When the rotation of the reels 5a to 5c reaches a predetermined speed, the stop switches 20a to 20c are activated, and when the player operates the stop switches 20a to 20c, the rotation of the corresponding reels 5a to 5c is stopped. To do.
[0036]
Here, when the combination of symbols stopped and displayed on the activated winning line is in a predetermined winning mode, the number of game medals corresponding to each winning mode is paid out as a prize, or It is added as credit.
[0037]
<Re-rotation of reel>
In the slot machine 1 described above, the reels 5a to 5c are re-rotated based on a predetermined condition in the process until the reels 5a to 5c are finally stopped.
The re-rotation of the reels 5a to 5c will be described using the flowcharts shown in FIGS. 3 to 6, the effect pattern selection table shown in FIG. 7, and the effect pattern table shown in FIG.
[0038]
FIG. 3 is a flowchart showing the re-rotation processing procedure of the reels 5a to 5c, FIG. 4 is a flowchart showing the reel effect selection processing procedure, FIG. 5 is a flowchart showing the reel effect execution processing procedure, and FIG. It is a flowchart which shows the procedure of a reel stop position return process. FIG. 7 is an explanatory diagram of an effect pattern selection table for selecting an effect pattern used in the re-rotation process of the reels 5a to 5c, and FIG. 8 is an explanatory diagram of an effect pattern table including a plurality of effect patterns. .
[0039]
In the re-rotation processing of the reels 5a to 5c, first, as shown in FIG. 3, it is determined whether or not the stopped symbol combination is a replay winning mode (S1), and any of the stopped symbol combinations is selected. It is determined whether or not the winning mode is (S2).
Here, when the combination of the stopped symbols is a replay winning mode or any one of the winning modes, the reels 5a to 5c are not re-rotated.
[0040]
On the other hand, if the combination of the symbols that have been stopped is not a replay winning mode and is not any of the winning modes, the current reel stop position is stored in the RAM 35 or the like (S3), and what effect is to be performed. A reel effect selection process (S4) for selecting, a reel effect execution process (S5) for actually performing an effect, and a return position of the reels 5a to 5c based on the reel stop position stored in the RAM 35 or the like. A reel stop position return process (S6) is performed.
[0041]
The reel effect selection process (S4) described above is a process for selecting a predetermined effect pattern from a plurality of effect patterns in accordance with the gaming state. As shown in FIG. 4, a random number used for the lottery is extracted. (S11) It is determined whether a big bonus game or a regular bonus game is in progress (S12).
Here, when the game is in the big bonus game or the regular bonus game, the processing is returned without performing the effect by the re-rotation of the reels 5a to 5c.
[0042]
On the other hand, if it is not during the big bonus game or the regular bonus game, it is further determined whether or not the game is a general game (S13).
Here, in the case of a general game, an effect pattern selection table for the general game is set (S14), and when the general game is not being performed, that is, when the start of a special game is permitted in the internal lottery, An effect pattern selection table for bonus internal winning is set (S15), and an effect pattern is selected based on the result of the internal lottery and the extracted random number value (S16).
As described above, the effect by the re-rotation of the reels 5a to 5c is performed only during the general game or during the bonus internal winning.
[0043]
As shown in FIG. 7 (a), the production pattern selection table for the general game used during the general game includes “losing”, “cherry”, “plum”, “bell”, “regular bonus (RB)”, Each of the internal winning combinations “Big Bonus (BB)” corresponds to one of a plurality of production patterns “1” to “18” and “No start (no re-rotation)”. .
[0044]
There are 256 random numbers “0” to “255” for selecting the effect pattern from the effect pattern selection table for the general game.
For example, when the internal winning combination is “Cherry”, as shown in FIG. 7A, if the random number value is “0” to “169”, the production pattern “Do not start” is selected, When the numerical value is “170” to “182”, the effect pattern “4” is selected, and when the random number value is “183” to “217”, the effect pattern “7” is selected, and the random value is “218”. ”To“ 232 ”, the effect pattern“ 10 ”is selected, and if the random number value is“ 233 ”to“ 247 ”, the effect pattern“ 11 ”is selected, and the random value is“ 248 ”to“ 252 ”. "12" of the effect pattern is selected, and "17" of the effect pattern is selected if the random number values are "253" to "255".
[0045]
In addition, as shown in FIG. 7B, the effect pattern selection table for bonus internal winning used when special games are permitted in the internal lottery is “lost”, “cherry”, “plum”, “ Each of the internal winning combinations “bell” corresponds to one of a plurality of effect patterns “1” to “18” and “does not start (does not re-rotate)”.
[0046]
The random number for selecting the production pattern from the production pattern selection table for the bonus internal winning is composed of 256 “0” to “255”.
For example, when the internal winning combination is “Cherry”, as shown in FIG. 7B, if the random number value is “0” to “69”, the production pattern “Do not start” is selected, If the numerical value is “70” to “89”, the production pattern “1” is selected, and if the random value is “90” to “109”, the production pattern “2” is selected, and the random value is “110”. ”To“ 122 ”, the production pattern“ 4 ”is selected, and if the random number value is“ 123 ”to“ 177 ”, the production pattern“ 7 ”is selected, and the random value is“ 178 ”to“ 202 ”. "10" of the effect pattern is selected, "11" of the effect pattern is selected if the random value is "203" to "227", and the random value is "228" to "242" When the production pattern “12” is selected and the random number values are “243” to “255” "17" is selected in the output pattern.
[0047]
As shown in FIG. 8, each production pattern selected in this manner causes at least one reel 5a-c to be re-rotated from the left, middle, and right reels 5a-c. It consists of 18 types “1” to “18”.
In this effect pattern, there are two types of rotation directions, “normal” and “reverse”, two types of rotation speeds of “low speed” and “high speed”, and rotation times of “5 seconds”, “12 seconds”, and “pause”. There are three types. Further, there are three types of rotation times of “pause”: “first half 9 seconds, second half 9 seconds”, “first half 6 seconds, second half 6 seconds” and “first half 12 seconds, second half 12 seconds”. Furthermore, there are four types of stop symbols, “7”, “BAR”, “plum”, and “cherry”.
That is, each effect pattern is configured by combining the reels 5a to 5c to be rotated, the rotation direction, the rotation speed, the rotation time, and the temporary stop symbol.
[0048]
For example, in the effect pattern “1”, the left reel 5a is rotated again in the reverse direction at a low speed for 5 seconds. In the effect pattern “12”, all the left, middle, and right reels 5 a to 5 c are rotated again in the reverse direction at a high speed for 5 seconds. In the production pattern “18”, all the left, middle, and right reels 5a to 5c re-rotate in the reverse direction at a high speed for 12 seconds, then temporarily stop at “7”, and then left, middle, and right. All the reels 5a to 5c are rotated again in the reverse direction at high speed for 12 seconds.
[0049]
In the reel effect execution process (S5) described above, as shown in FIG. 5, the reels 5a to 5c are re-rotated based on the selected effect pattern (S21).
[0050]
In the reel stop position return process (S6) described above, as shown in FIG. 6, the reels 5a to 5c are rotated and stopped to the reel stop position stored in the RAM 35 or the like (S31).
[0051]
<Winning mode>
In addition to a general winning mode, the predetermined winning mode includes a special winning mode which is a starting condition for a special game that is more advantageous to the player than a general game. Furthermore, the special prize mode includes a so-called big bonus mode and a regular bonus mode.
[0052]
Here, specific examples of the winning mode include the so-called small roles such as “cherry”, “plum”, and “bell”, and the game medals in the next game. There is a winning mode called replay (re-game) in which a game can be played without having to be entered.
[0053]
In a normal case, if the winning mode is not configured in the game won internally, the established internal winning combination will not be carried over to the next and subsequent games. The payout of game medals is relatively small payout of 15 or less. On the other hand, a big bonus referred to as a special prize mode (a big time with CT including a game called a so-called challenge time (CT) in which the stop control of the reels 5a to 5c is canceled by a random lottery for a predetermined period after the end of the big bonus) (Including bonuses) and regular bonuses occur when a combination of predetermined special game start symbols is aligned on the winning line.
[0054]
Such special games called big bonuses and regular bonuses are configured such that a winning mode is generated with a higher probability than in a normal gaming state. These winning modes are because the internal lottery probability is very low compared to small roles and replay winnings, so when the winning mode is not configured in the game won internally, that is, when the special winning mode is not configured on the winning line. Even if there is, the internal winning state can be carried over to the next and subsequent games.
