[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.
[0002]
[Prior art]
In the present specification, a pachislot machine is described as an example, so that medals are used as game media. However, game media include other media such as coins and pachinko balls. Further, “inserting medals (game media)” includes betting a credited medal with a bet button or the like in addition to actually inserting a medal into the medal slot. In addition, the winning design that constitutes the winning combination that won the winning combination by the electronic lottery, the state that the winning pattern constituting the winning winning combination can be aligned on the winning active line, and the winning combination that won the internal winning A state that is aligned on the winning line is regarded as winning.
[0003]
Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and given a certain value to the medal that is the game medium, various medals earned by playing games Can be replaced. For this reason, the player generally aims to acquire a large number of medals, and generally selects a table that is easy to obtain the right to shift to the bonus game mode and plays a game. The bonus game mode includes, for example, a big bonus (hereinafter referred to as BB) mode and a regular bonus (RB) mode. In particular, the BB mode is shifted to the RB mode a predetermined number of times, and before the transition to the RB mode, Since the transition to the RB introduction mode in which the winning probability is high, a large amount of medals can be obtained in a short period of time.
[0004]
Having the expectation of winning a large number of medals in a short period is an important factor in attracting players to slot machines, and there are many models that have been devised in various ways to enlighten players' gambling Tend to be offered. As one of such models, for example, a model provided with a so-called stock function is provided in which the selected BB or RB is stored when winning the BB to be shifted to the BB mode or the RB to be shifted to the RB mode. ing.
[0005]
Some models provided with a stock function are provided with a game mode called a replay time (RT) mode, for example. When the mode is changed to RT mode, the winning combination lottery table for determining the winning combination is switched to a winning combination lottery table with a high replay winning probability, and whether or not replay can be won in the case of winning the replay Is determined by lottery. Further, during the RT mode, reel stop control is performed so that the winning BB or RB cannot be won, and the winning BB or RB during the RT mode is stored.
[0006]
The number of games in the RT mode is determined by lottery, and when the determined number of games are consumed, the RT mode is terminated. Then, the winning combination lottery table is switched to a normal table, and reel stop control is performed so that the stored BB and RB can be won, and BB and RB are released. After the transition to the BB mode or the RB mode, the transition is made to the RT mode again. However, when the number of games in the RT mode is small, the transition to the BB mode or the RB mode is performed again in a short period of time. It becomes possible to win medals.
[0007]
[Problems to be solved by the invention]
However, in the slot machine having the stock function as described above, the number of games in the RT mode is determined to be one of a plurality of types of games set in advance by lottery. When the mode is changed to the long RT mode, there are disadvantages that not only the player consumes a large number of medals but also the game becomes monotonous. Also, when the number of games determined by lottery is played and the RT mode ends, BB and RB are released, so the tension to release BB and RB is light, and the game becomes monotonous There was a problem that.
[0008]
In order to solve the above problems, the present invention provides a gaming machine that allows a player to have a sense of expectation that a large amount of profit can be obtained in a short period of time when releasing a stored winning combination.

[0014]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the slot machine 10 is provided with a normal mode, a BB mode, and a special mode RB mode. The BB mode is terminated when the game is shifted to the RB mode three times or when the game in the RB introduction mode is performed 30 times. The RB mode ends when the specific winning combination is won 8 times or when 12 games are played.
[0015]
If the RB is won in the normal mode, the RB is stored. The stored RB is released when an RB release lottery performed for each game is won. At the end of the RB mode and the BB mode, a lottery is performed as to whether or not to shift to the RB probability variation mode in which the winning probability in the RB release lottery is high. The RB probability variation mode is shifted to the RB mode twice, that is, the RB probability variation mode is shifted twice. In the RB probability variation mode, a probability variation continuation lottery that determines whether or not to continue the RB probability variation mode is performed every time the game is played, and if the probability variation continuation lottery is won, the next RB mode is further shifted to the RB mode twice. Until it is done, that is, after the next RB mode, the mode is further shifted twice to the RB probability variation mode.
[0016]
In the slot machine 10, four display windows 13 are provided in the front door 12 of the housing 11, and the first reel 14 a, the second reel 14 b, the third reel 14 c, and the sub reel 15 rotate behind each display window 13. Built in freely. As is well known, a plurality of types of patterns are arranged on the outer periphery of the first to third reels 14a to 14c at a constant pitch, and three patterns per reel can be observed through the display window 13 when the reels are stopped. Become. As a result, a total of five straight winning winning lines, each of which has a pattern of each reel, are set, with three horizontal lines and two diagonal lines.
[0017]
Prior to the start of the game, when one medal is inserted from the medal slot 16, the winning line in the center is activated, 3 for 3 in the side, and 2 for the 3 in addition to the diagonal 5 The book winning line is activated. Further, it is possible to credit (store) up to 50 medals, and the number of credited medals is displayed on the credit number display unit 17. For example, four symbols per reel can be observed from the display window 13, and in addition to the four horizontal winning lines, another prize that is folded to combine one symbol for each reel. It is also possible to set an effective line.
[0018]
The rightmost sub-reel 15 is activated each time a game is played in the RB probability variation mode, and is rotated when a betting operation for medals is performed. The sub reel 15 has “◎” indicating that the number of transitions to the RB probability variation mode is two, “◯” indicating that the number of transitions to the RB probability variation mode is one, and the next RB mode. “×” indicating that the RB probability variation mode is terminated when the process shifts to “” is drawn. In addition, you may set suitably the pattern which shows the frequency | count that RB probability variation mode continues, such as using a number, a mark, and a symbol.
[0019]
By operating these stop buttons 19a to 19c, the first to third reels 14a to 14c corresponding to the buttons are individually stopped. Various operation buttons such as a bet button 20 and a payout button are provided on the operation panel above the stop buttons 19a to 19c. Since the functions of these operation buttons are well known, the details thereof are omitted.
[0020]
A chance lamp 21 is provided below the sub reel 15. The chance lamp 21 is turned on when a lottery performed when the start lever 18 is operated in a game in the RB probability variation mode is won. The chance lamp 21 indicates whether or not to shift to the RB probability variation mode continuously even after the next RB mode ends. When “◎” or “◯” is displayed on the sub reel 15 and the chance lamp 21 is turned on, the RB probability variation mode is continued even after the next RB mode ends.
[0021]
A medal tray 22 is provided at the lower portion of the housing 11, and a payout medal obtained when a prize is obtained in the game is paid out from the payout opening 23 to the medal tray 22.
[0022]
As shown in FIG. 2, the operation of the slot machine 10 is basically controlled by a control unit 30 including a CPU 30 a and a memory 31. In addition to the CPU 30a, the control unit 30 includes an electronic lottery unit 39, a winning combination determination unit 40, an RB flag storage unit 41, an RB flag release signal generation unit 42, an RB flag release lottery unit 43, and an RB release probability variation lottery unit 44 which will be described later. A first probability variation continuation lottery unit 45 and a second probability variation continuation lottery unit 46 are provided.
[0023]
The medal sensor 32 detects an appropriate medal inserted from the medal slot 16 and inputs it to the CPU 30a. A selector is incorporated in the back of the medal insertion slot 16, and an inappropriate medal is discharged to the medal tray 22. Further, when a selector inserts a medal at an inappropriate timing, for example, a medal inserted in the middle of a game or with various operation buttons pressed, without passing through the medal sensor 32. It is discharged to the medal tray 22.
[0024]
Since the number of medals to be inserted prior to the start of the game is limited to 1 to 3, the medal sensor 32 also detects medals inserted after the fourth one when the credit function is not used. Without being discharged to the medal tray 22. The credit function is turned on / off every time the payout button is pushed. When the credit function is on, medals inserted after the fourth sheet are also detected by the medal sensor 32 and credited into the slot machine up to 50 sheets. The number of credited medals is digitally displayed on the credit number display unit 17. When the credit function is used, a medal insertion operation is performed by the operation of the 1 bet button or the MAX bet button described above, and the bet number is sequentially subtracted from the credit number. In addition, when a game is performed and a winning with a medal payout is obtained, a payout medal is also credited, and a medal credited when the payout button is operated is paid out to the medal tray 22.
[0025]
The CPU 30a counts the number of 1 to 3 medals inserted prior to the start of the game based on the detection signal from the medal sensor 32, and thereby determines the number of activated payable lines. The number of credits is counted by another credit medal counter (not shown).
[0026]
The start signal sensor 33 inputs a game start signal to the CPU 30a when the start lever 18 is operated after 1 to 3 medals are inserted. Upon receiving the game start signal, the CPU 30a rotates the first to third reels 14a to 14c based on the game execution program stored in the ROM area of the memory 31 and starts the game process. In addition to the normal mode, the game execution program includes a program for executing a game process by shifting to the BB mode or the RB mode.
[0027]
The reel drive controller 34 controls the drive and stop of each reel. Each reel is fixed to a drive shaft of an individual stepping motor 35a to 35d, and each reel is controlled by controlling the driving of each stepping motor 35a to 35d. The RAM area of the memory 31 is a working area and is used for temporary storage or rewriting of flags and data used for each game.
[0028]
Since the stepping motors 35a to 35d rotate at a rotation angle corresponding to the number of supplied drive pulses, the rotation angles of the first to third reels 14a to 14c and the sub reel 15 are controlled by the CPU 30a controlling the number of supplied drive pulses. Further, the stop position of the reel can be determined by stopping the supply of the drive pulse. Each reel is integrally formed with reflection signal portions 36a to 36d at its reference position, and the photosensors 37a to 37d photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 37a to 37d are input to the CPU 30a as a reset signal for each reel.
[0029]
The CPU 30a is provided with a pulse counter for each of the stepping motors 35a to 35d, and counts the number of drive pulses supplied to each of the stepping motors 35a to 35d. When the reset signal is input from the photosensors 37a to 37d, the count value of the corresponding pulse counter is cleared. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.
[0030]
A picture table is stored in the ROM area of the memory 31, and the picture table represents the number of drive pulses corresponding to the rotation angle from the reference position of each reel, and the picture representing each picture arranged on the reel at a constant pitch. A code is associated. Therefore, by monitoring the count value of the pulse counter for each reel, for example, it is possible to identify which pattern has moved on the center winning effective line, and how much more the reel should be rotated. It is possible to predict whether the target pattern will move on the winning line.
[0031]
The stop button sensors 38a to 38c input a stop signal for each reel to the CPU 30a when the stop buttons 19a to 19c are operated. The start lever 18 is operated to start the rotation of all reels. When these rotations reach a steady speed, the operation of the stop buttons 19a to 19c is validated. Thereafter, by operating these, stop control of the corresponding first to third reels 14a to 14c is started.
[0032]
The stop control of the first to third reels 14a to 14c is performed within a range (drawing range) of five winning designs 0 to 4 frames. For example, when the stop buttons 19a to 19c are operated, the winning is effective. In the case where a winning design that constitutes the winning combination won in the lottery is included in the four winning designs that are consecutive from the winning design located on the line, the first to third reels 14a to 14a The time until 14c stops is delayed, and the winning design constituting the winning combination is stopped on the winning line.
[0033]
In addition, when the stop buttons 19a to 19c are operated so that a winning combination not determined by the winning combination determining unit 40 is won, the first selection is made so that a winning design that has not been won does not stop on the winning effective line. -Stop control of the third reels 14a to 14c is performed (kicking control). Further, when a plurality of stop buttons are operated, only the reel with the earlier timing is stopped, and when fully operated simultaneously, none of the reels are stopped. In addition, the reel stop control is not limited to the winning pattern that constitutes the winning combination, so that the player is informed of the winning combination that has won the prize by the type of the pattern stopped on the winning effective line, or the combination of the patterns. Reach eyes may be displayed. As a result, the CPU 30a and the reel drive controller 34 function as reel stop control means.
[0034]
The CPU 30a operates the electronic lottery unit 39 in response to the game start signal. The electronic lottery unit 39 includes a random number generator and a random number sampling circuit, and draws one random value every time the game is started. The random value selected by lottery is input to the winning combination determining unit 40. The winning combination determination unit 40 determines what winning combination is to be given in the currently executed game according to the input value. Thus, the electronic lottery unit 39 and the winning combination determining unit 40 function as a winning combination determining unit.
[0035]
The winning combination determination unit 40 is provided with a plurality of winning combination lottery tables in which random values are grouped according to their sizes. In the first winning combination lottery table, random numbers sampled in the game in the normal mode perform only BB giving the right to shift to the BB mode, RB giving the right to shift to the RB mode, and paying out a predetermined number of medals. Determining which pattern belongs to, such as a small role corresponding to a small role winning pattern, a replay that gives the right to play the next game with the same number of bets without inserting medals, or a winning that does not cause any wins, that is, a winning determination Used for. Note that there are a plurality of types of small role winning designs, and a payout medal is assigned to each. Then, the winning type and the design are determined depending on which winning design the sampled random number value belongs to.
[0036]
In addition to the first winning combination lottery table, the winning combination determining unit 40 is provided with a table used in a game in which BB has won an internal prize, a game in the RB introduction mode, a game in the RB mode, and the like. .
[0037]
The RB flag storage unit 41 includes a memory, and the RB flag is written every time the RB is determined by the winning combination determining unit 40 in the game in the normal mode. Thereby, the RB won in the normal mode is stored. In this way, the RB flag storage unit 41 functions as a special winning combination storage unit. When one RB flag is read, the mode is shifted once to the RB mode.
[0038]
The RB flag release signal generator 42 is activated when it is determined to release RB. When the RB flag release signal generator 42 is activated, the RB release signal is input to the reel drive controller 34. In response to this, the CPU 30a and the reel drive controller 34, when the stop buttons 19a to 19c are operated, if there is an RB winning design within the pull-in range, Stop control of the first to third reels 14a to 14c is performed. As described above, the RB flag release signal generator 42, the CPU 30a, and the reel drive controller 34 function as special winning combination release means.
[0039]
As shown in FIG. 3, the RB flag release lottery unit 43 functions as a special winning combination release lottery unit, and includes an electronic lottery unit 50, a high probability RB release probability table 51, and a low probability RB release probability table 52. ing. The RB flag release lottery unit 43 is activated each time the game is played in the normal mode and the RB probability variation mode. The high probability RB release probability table 51 is grouped into random values so that the probability of releasing the RB flag is higher than that of the low probability RB release probability table 52. In the game in the normal mode, the random value sampled by the electronic lottery unit 50 is collated with the low probability RB release probability table 52, and in the RB probability variation mode, the random value sampled by the electronic lottery unit 50 is compared with the high probability RB release probability table 51. Is matched. Thereby, it is determined whether or not the stored RB can be won. Switching between the high probability RB release probability table 51 and the low probability RB release probability table 52 is performed by the CPU 30a according to each game mode. As a result, the CPU 30a functions as a release probability table switching unit.
[0040]
The RB release probability variation lottery unit 44 is activated at the end of the BB mode and the RB mode, and determines whether or not to proceed to the RB probability variation mode in the BB mode or the RB mode. Whether or not to switch from the low probability RB release probability table 52 to the high probability RB release probability table 51 is determined by lottery. In this way, the RB release probability variation lottery unit 44 functions as a release probability table switching lottery means.
[0041]
The first probability variation continuation lottery section 45 functions as a first probability variation continuation lottery means, and is operated when the start lever 18 is operated in the RB probability variation mode game. In the first probability variation continuation lottery unit 45, probability variation continuation lottery is performed, and it is determined by lottery whether or not the RB probability variation mode is to be shifted twice after the next RB mode. The CPU 30a performs lighting control of the chance lamp 21 according to the lottery result in the first probability variation continuation lottery unit 45.
[0042]
The second probability variation continuation lottery section 46 functions as a second probability variation continuation lottery means, and is activated when the bet button 20 is operated in a game in the RB probability variation mode. In the second probability variation continuation lottery section 46, probability variation continuation lottery is performed, and it is determined by lottery whether or not to shift to the RB probability variation mode twice after the next RB mode. The CPU 30a controls the driving of the sub reel 15 in accordance with the lottery result in the second probability variation continuation lottery unit 46.
[0043]
The medal hopper 47 pays out a specified number of payout medals to the medal tray 22 according to the type of winning combination, or adds the specified number to the credit counter. A payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM area of the memory 31, and the CPU 30a reads this to drive the medal hopper 47.
[0044]
Next, the operation of the slot machine configured as described above will be described. As shown in FIGS. 4 to 7, when 1 to 3 medals are inserted prior to the start of the game in the normal mode, the number of inserted medals is counted by the CPU 30a. Thereafter, when a game start operation is performed by the start lever 18, a game start signal is input from the start signal sensor 33 to the CPU 30a, and rotation of the first to third reels 14a to 14c is started.
[0045]
Simultaneously with the operation of the start lever 18, the electronic lottery unit 39 samples a random number and collates the value with the first winning combination lottery table of the winning combination determination unit 40. As a result, the type of the winning combination or winning combination is determined, and the winning combination determination signal is fed back to the CPU 30a. When the type of winning combination is determined by the winning combination determining unit 40, the operation of the stop buttons 19a to 19c is validated. The CPU 30a monitors the operation timing of the stop buttons 19a to 19c while referring to the count value of the aforementioned pulse counter provided for each reel, and the winning design determined by the winning combination determining unit 40 is stopped on the winning winning line. Stop control of the 1st-3rd reels 14a-14c is performed so that it may be easy.
[0046]
When the winning combination determining unit 40 determines the RB, the RB flag is written in the RB flag storing unit 41 and the RB is stored. In the normal mode, every time a game is played, the RB flag release lottery unit 43 is operated, and an RB release lottery for determining whether or not to release the stored RB flag is performed. In the RB flag release lottery unit 43, the random value sampled by the electronic lottery unit 60 is collated with the high probability RB release probability table 51.
[0047]
When the RB release lottery is won, the CPU 30a and the reel drive controller 34 perform stop control of the first to third reels 14a to 14c so that the RB can win. When the RB is won, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts to the RB mode. The RB mode is ended when the specific winning combination is won eight times or when twelve games are played.
[0048]
When BB is determined by the winning combination determination unit 40 and BB is won, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts to the BB mode. In the BB mode, the mode is first shifted to the RB introduction mode, and a game is played with 1 to 3 medal bets. Then, replay is determined in the game in the RB introduction mode (in the slot machine of the present embodiment, replay is substituted as a winning combination for shifting to the RB mode), and when this is won, the game is switched to the RB mode. The The BB mode is ended when the game in the RB introduction mode is performed 30 times or when the game is shifted to the RB mode three times.
[0049]
At the end of the BB mode and the RB mode, the RB release probability variation lottery unit 44 is operated, and it is determined whether or not to shift to the RB probability variation mode following the BB mode or the RB mode. If the lottery in the RB release probability fluctuation lottery unit 44 is not won, the mode is shifted to the normal mode after the BB mode or the RB mode is finished.
[0050]
When the lottery in the RB release probability fluctuation lottery unit 44 is won, the RB mode is changed to the RB probability fluctuation mode following the BB mode or the RB mode. In the game in the RB probability variation mode, when the bet button 20 is first operated to place a bet on a medal, the second probability variation continuation lottery unit 46 is activated. In the second probability variation continuation lottery section 46, probability variation continuation lottery is performed, and it is determined by lottery whether or not to shift to the RB probability variation mode twice after the next RB mode.
[0051]
When the probability variation continuation lottery is completed, the CPU 30a and the reel drive controller 34 drive the sub reel 15. When the lottery at the second probability variation continuation lottery section 46 is won, the sub reel 15 is stopped to display “◎”. If the lottery in the second probability variation continuation lottery section 46 is not won, the sub reel 15 is stopped so as to display “◯”.

When the start lever 18 is operated after the betting of the medal is performed by operating the bet button 20, the first probability variation continuation lottery unit 45 is operated. The first probability variation continuation lottery unit 45 also performs the probability variation continuation lottery, and it is determined by lottery whether or not to shift to the RB probability variation mode twice after the next RB mode. When winning the lottery in the first probability variation continuation lottery unit 45, the CPU 30a lights the chance lamp 21. If the lottery in the first probability variation continuation lottery unit 45 is not won, the CPU 30a keeps the chance lamp 21 off and keeps it off.
[0053]
When “◎” is displayed on the sub reel 15 and the chance lamp 21 is turned on, the remaining number of transitions to the RB probability variation mode is two. When “○” is displayed by the sub reel 15 and the chance lamp 21 is turned on, the remaining number of transitions to the RB probability variation mode is one. Since the remaining RB probability variation mode is always transferred once, if it is determined to display “◯” by the sub reel 15, the CPU 30a regardless of the lottery result in the first probability variation continuation lottery unit 45. Turns on the chance lamp 21.
[0054]
When the RB release lottery is won and the RB is won and the RB mode is shifted to, the RB mode is changed to the RB probability variation mode. In the RB probability variation mode, as described above, every time a game is played, the second probability variation continuation lottery unit 46 and the first probability variation continuation lottery unit 45 perform a lottery.
[0055]
When the lottery at the second probability variation continuation lottery section 46 is won, the sub reel 15 is stopped to display “◎”. If the lottery in the second probability variation continuation lottery section 46 is not won, the sub reel 15 is stopped to display “x”. When “◎” is displayed on the sub reel 15 and the chance lamp 21 is turned on, the remaining number of transitions to the RB probability variation mode is two. When “x” is displayed by the sub reel 15, the remaining number of transitions to the RB probability variation mode is 0, and the game after the next RB mode is played in the normal mode. When the RB probability variation mode is entered, the above-described game flow is repeated.
