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 makes up the winning combination that won the winning combination by electronic lottery, the state that the winning design that constitutes the winning winning combination can be aligned on the winning effective 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 stock time (ST) mode, for example. The ST mode is shifted to, for example, when BB is won, and during the ST mode, the probability of winning a replay that allows the next game to be played without inserting medals is increased. For this reason, during the ST mode, the player can receive a lottery to determine the winning combination while suppressing consumption of medals. When BB or RB is stored during the ST mode, the stored BB or RB is released after the end of the ST mode, and the mode is continuously shifted to the BB mode or the RB mode. In a model provided with the ST mode, when a plurality of BBs and RBs are stocked, the mode is repeatedly shifted to the BB mode or the RB mode, so that a large number of medals can be obtained in a short period of time. For this reason, the interest of the player in the game can be enhanced.
[0006]
[Problems to be solved by the invention]
However, in the above slot machine, the stored BB and RB are only sequentially released after the end of the ST mode. Therefore, if the player is repeatedly shifted to the ST mode, the player can predict the development of the game, and the game It was easy to get bored.
[0007]
In order to solve the above-mentioned problems, the present invention prevents a game from becoming monotonous when releasing a stored winning combination, and can increase the expectation of releasing the stored winning combination. It is an object to provide a machine, a program, and a recording medium.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, the slot machine 10 is provided with a normal mode and a BB 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 a predetermined winning pattern is won eight times or when twelve games are played. When BB which is a special winning combination is won in the normal mode, BB is forcibly stored. Then, in a game in the normal mode, when a prize is won for a specific winning combination, and a lottery for determining whether or not to enable winning of a plum on a predetermined winning active line is won, the stored BB is released. A BB release lottery is performed to determine whether or not to do so. When the BB release lottery is won, reel stop control is performed so that BB can be won.
[0012]
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.
[0013]
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.
[0014]
The rightmost sub-reel 15 is rotated together with the first to third reels 14a to 14c when the start lever 18 is operated when the BB is won in the game in the normal mode. On the sub reel 15, "BB" indicating that BB has won an internal prize is drawn, and a blank portion where nothing is drawn is also provided. The sub reel 15 is normally stopped at a position where a blank portion is displayed, and it is determined to release the stored BB. When the BB wins an internal prize, the sub reel 15 is stopped at a position where “BB” is displayed. In addition, the display indicating that BB has won an internal prize is not limited to “BB”, and may be appropriately displayed by a picture or a mark. Further, other winning combinations other than RB such as BB and small combinations may be displayed. In this case, it is preferable not to display a loss before a reel stop operation is performed.
[0015]
By operating these stop buttons 19a to 19c, the first to third reels 14a to 14c corresponding to the buttons are individually stopped. The operation panel above the stop buttons 19a to 19c is provided with various operation buttons such as a 1-bet button, a MAX bet button, and a payout button that are operated when a game is played in a state where medals are credited. Since the functions of these operation buttons are well known, the details thereof are omitted.
[0016]
A medal tray 20 is provided at the lower portion of the housing 11, and a payout medal obtained when a winning is obtained in the game is paid out from the payout opening 21 to the medal tray 20.
[0017]
As shown in FIG. 3, the operation of the slot machine 10 is basically controlled by a microcomputer including a CPU 30 and a memory 31. In addition to the control unit 30a, the CPU 30 is provided with an electronic lottery unit 39, a winning combination determination unit 40, a BB flag storage unit 41, a winning effective line lottery unit 42, a winning effective line determination table 43, and a BB release lottery unit 44 which will be described later. ing.
[0018]
The medal sensor 32 detects an appropriate medal inserted from the medal slot 16 and inputs it to the control unit 30a. A selector is incorporated in the back of the medal insertion slot 16 and an inappropriate medal is discharged to the medal tray 20. 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. The medal tray 20 is discharged.
[0019]
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 20. 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, the payout medal is also credited, and the credited medal is paid out to the tray 20 when the payout button is operated.
[0020]
The control unit 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 valid activated pay lines. The number of credits is counted by another credit medal counter (not shown).
[0021]
The start signal sensor 33 inputs a game start signal to the control unit 30a when the start lever 18 is operated after 1 to 3 medals are inserted. Upon receiving the game start signal, the control unit 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 that shifts to the BB mode and executes game processing.
[0022]
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.
[0023]
Since the stepping motors 35a to 35d rotate at a rotation angle corresponding to the number of supplied drive pulses, the control unit 30a controls the number of supplied drive pulses to control the first to third reels 14a to 14c and the sub reels 15. The rotation angle can be controlled, and 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 control unit 30a as a reset signal for each reel.
[0024]
A pulse counter is provided for each of the stepping motors 35a to 35d in the control unit 30a, 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.
[0025]
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.
[0026]
The stop button sensors 38a to 38c input a stop signal for each reel to the control unit 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.
[0027]
The stop control of the first to third reels 14a to 14c is performed within the range of four winning designs (retraction range). For example, when the stop buttons 19a to 19c are operated, the control is positioned on the winning line. If the winning symbols that make up the winning combination won in the lottery are included in the four winning symbols that are consecutive from the winning winning symbols, the first to third reels 14a to 14c are stopped. Is delayed, and the winning symbols constituting the winning combination are stopped on the winning line. Note that 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 controller 30a and the reel drive controller 34 function as reel stop control means.
[0028]
The control unit 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.
[0029]
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, a random number sampled in the game in the normal mode gives a right to shift to the BB mode, a small combination corresponding to a small combination winning pattern that only pays out a predetermined number of medals, It is used for determination of which picture belongs to, such as replay that gives the right to play the next game with the same bet number without inserting medals, or lose that does not generate any hits, that is, winning determination. Note that there are a plurality of types of small role winning designs (including the above-mentioned plums), 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.
[0030]
In addition to the first winning combination lottery table, the winning combination determination 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. Yes. When the winning combination is determined by the winning combination determination unit 40, a winning combination determination signal indicating the determined loss or the type of winning combination is input to the control unit 30a.
[0031]
The BB flag storage unit 41 includes a memory, and a BB flag (special winning combination flag) is written every time the winning combination determining unit 40 determines BB during the normal mode. As a result, the BBs won in the normal mode game are forcibly stored. Thus, the BB flag storage unit 42 functions as a special winning combination storage unit. When one BB flag is read, the mode is shifted once to the BB mode.
[0032]
The winning effective line lottery section 42 and the winning effective line determination table 43 function as winning effective line lottery means, and are activated when a plum is determined by lottery in the electronic lottery section 39 and the winning combination determining section 40. . The winning effective line lottery section 42 samples random values and collates the sampled random values with the winning effective line determination table 43. In the winning effective line determination table 43, random value grouping is performed. Each random value group includes, for example, a group to which three horizontal winning lines (hereinafter referred to as three lines) are assigned and a total of five winning lines (hereinafter referred to as five lines) including two horizontal lines and two diagonal lines. And a group to which a prize is awarded can be determined by collating random numbers.
[0033]
The BB release lottery unit 44 functions as a special winning combination release lottery unit, and is activated when it is determined that a prize can be won in, for example, five lines by lottery by the winning effective line lottery unit 42. In the BB release lottery unit 44, whether or not to release the BB flag stored in the BB flag storage unit 41 is determined by lottery. If the BB flag is not stored in the BB flag storage unit 41, the lottery result in the BB release lottery unit 44 is invalidated.
[0034]
The medal hopper 45 pays out a specified number of payout medals to the medal tray 20 according to the type of winning combination, or adds the specified number to the credit counter. The 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 control unit 30a reads this to drive the medal hopper 45.
[0035]
Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 4, 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 control unit 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 control unit 30a, and rotation of the first to third reels 14a to 14c is started.
[0036]
Simultaneously with the operation of the start lever 18, the electronic lottery unit 39 samples a random number, compares the value with the first winning combination lottery table of the winning combination determination unit 40, and determines the type of winning or winning combination, and the winning combination determination signal Is fed back to the control unit 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 control unit 30a monitors the operation timing of the stop buttons 19a to 19c while referring to the count value of the pulse counter provided for each reel, and the winning pattern determined by the winning combination determining unit 40 is on the winning active line. Stop control of the first to third reels 14a to 14c is performed so as to easily stop.
[0037]
When BB is determined by the winning combination determining unit 40, the BB flag is written in the BB flag storing unit 41 and the BB is stored. In the game in which the winning combination is determined by the winning combination determining unit 40, the winning effective line lottery unit 42 is operated, and random number sampling is performed. The random value sampled by the winning effective line lottery unit 42 is collated with the winning effective line determination table 43. Thereby, it is determined which of the three winning lines for the plum is three winning lines, or five winning lines including two horizontal lines plus two diagonal lines.
[0038]
When it is determined that the prize can be won in three lines, the player operates the stop buttons 19a to 19c, and when the plum is won, the medal hopper 45 is driven and the payout medal is paid out. .
[0039]
If it is determined that the plum can be won in 5 lines, for example, if the player operates the stop buttons 19a to 19c so that the plum is won in the diagonal winning line, the plum is in the diagonal winning line. Can be aligned. When the prize is won, the medal hopper 45 is driven and the payout medal is paid out.
[0040]
In addition, it is determined that the plum can be won in five lines, and when the plum is won, the BB release lottery unit 44 is operated. A lottery is performed in the BB release lottery unit 44, and it is determined whether or not to release the BB flag stored in the BB flag storage unit 41 and to make an internal prize for the BB. When it is determined to release the stored BB flag, the control unit 30a reads the BB flag from the BB flag storage unit 41, and sets the number of BB flags written in the BB flag storage unit 41 to “1”. Subtract.
[0041]
And the control part 30a performs stop control of the 1st-3rd reels 14a-14c so that BB winning design may stop easily on a winning effective line, and it is set as the state which BB won internally. Further, when the game is started, the control unit 30a rotates the first to third reels 14a to 14c and the sub reel 15, and before the operation of the stop buttons 19a to 19c is validated, “BB” Is stopped at a position where “” is displayed, and the player can detect that BB has won an internal prize.
[0042]
When BB is won, the control unit 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 game in the RB mode is performed with one medal bet. The RB mode is ended when a predetermined winning picture is won eight times or when twelve games are played. 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.
[0043]
As a preliminary knowledge when playing a game, for example, a sticker with a game method on the case 11 will be used when a prize is won for a plum and the prize can be won with 5 lines. Affixing or informing the player by a method such as distributing a strategy booklet describing the gaming method of the slot machine 10 at the game hall prevents the game from becoming monotonous when the present invention is implemented. It will be more effective in increasing the expectation for the release of the stored winning combination.
