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. Furthermore, a state where the winning pattern is aligned on the winning line is a winning state, and a state where a winning combination is drawn by electronic lottery in a state before winning is determined as an internal 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]
Providing the expectation that a large number of medals can be obtained in a short period is an important factor in attracting players to the slot machine. In addition to the bonus game mode, a special mode that can expect a large number of medals is provided. There is a tendency to provide a large number of models that have been devised in various ways in order to enlighten the players. As one of the special modes, there is known an assist time (AT) mode in which a reel stop operation mode is informed so as to increase a player's profit acquisition probability. In the AT mode, for example, the player is notified of the color of a picture to be stopped on the winning line, the operation order of the stop button, or the like by a sub-reel provided separately from the three reels, a liquid crystal panel, or voice. When the player operates the stop button in accordance with this notification, it becomes easier to win the small part that has won the internal prize, so that the profit acquisition probability can be increased.
[0005]
[Problems to be solved by the invention]
However, in the above slot machine, for example, when a lottery is won or a specific winning combination is won, the right to enter the AT mode is obtained, and whether or not the AT mode is started after the right is obtained. When the lottery is performed and the lottery is won, the AT mode is started. Even if the right to enter the AT mode is obtained, has the right to enter the AT mode been obtained until the AT mode is started? Since the player cannot detect whether or not, the game may end with the right to shift to the AT mode, and the player may lose a great profit.

DETAILED DESCRIPTION OF THE INVENTION
The slot machine 10 shown in FIG. 1 is provided with a normal mode, a BB mode as a special mode, an AT mode as a first special mode, and an RT mode as a second special mode. The BB mode is shifted when BB is won in the electronic lottery performed in the normal mode, and is shifted to the RB mode three times or when the game in the RB introduction mode is performed thirty times. In the RB introduction mode, the game is played by inserting 1 to 3 medals, and the winning probability of the small role is increased. In a game in the RB introduction mode, the winning combination for shifting to the RB mode is won, and when the winning combination is won, the mode is switched to the RB mode. The RB mode ends when a predetermined winning combination is won eight times or when 12 games are played.
[0014]
There are three conditions for shifting to the AT mode. The first one is won when a replay (replay) is won, and when an AT transfer lottery performed twice is won successively, the game is transferred. Second, in the first game after the end of the BB mode, when a winning combination (for example, bell) that can be won by operating the stop buttons 19a to 19c in a specific order is won, In addition, when the AT shift lottery performed when the bell is won is won, the shift is made. The third is transferred when the RT transfer lottery performed when the BB is won is won. In this case, after BB mode ends In the RT mode, the number of games played in the RT mode reaches the number determined by lottery, RT mode When is finished Transition to AT mode.
[0015]
There are two lottery states for RT transition lottery: high probability state and low probability state , That do it, First, the normal mode game is started when the lottery state of the RT transition lottery is in a high probability state. If you win the RT transition probability drop lottery that is performed for each game, Until winning BB After Normal mode game is RT lottery lottery status from high probability Transition to low probability state. RT lottery lottery status is If you win BB with high probability, Then run If the winning probability of the RT transfer lottery is high and BB is won in a low probability state, Then run The winning probability of the RT transfer lottery is low. The predetermined winning combination is not limited to the bell and may be set as appropriate.
[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 winning symbols are arranged at a constant pitch on the outer periphery of the first to third reels 14a to 14c, and three symbols 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 functions as an informing means, and starts rotating together with the first to third reels 14a to 14c by the operation of the start lever 18 when winning a bell in an AT mode game. On the outer periphery of the sub reel 15, a plurality of kinds of patterns indicating the order of performing the stop operation of the first to third reels 14a to 14c are drawn, and in addition to these, a blank portion on which nothing is drawn is also provided. . It should be noted that the pattern drawn on the outer periphery of the sub reel 15 is preferably an appropriate pattern, and is not limited to the pattern, and may be a mark or a number, for example. In addition, on the sub-reel 15, an appropriate notification is drawn by appropriately drawing a picture such as a picture indicating that a specific winning combination has been won or a picture indicating an expectation level regarding whether or not a specific winning combination has been won. It's okay.
[0019]
The sub-reel 15 is normally stopped at a position where a blank portion is displayed, and a position where a reel stop operation sequence is displayed that enables winning the winning bell when winning a bell in an AT mode game. Stopped at. The player can reliably win the bell by operating the stop buttons 19a to 19c according to the order displayed by the sub reels 15.
[0020]
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.
[0021]
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.
[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 and the memory 31, the control unit 30 includes an electronic lottery unit 39, a winning combination determining unit 40, an RT mode transition lottery unit 41, an RT end game number lottery unit 42, an RT start game number lottery unit 43, and an AT mode. A transition lottery unit 44 and an RT transition probability fall lottery unit 45 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 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.
[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 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.
[0025]
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.
[0026]
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).
[0027]
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. The game execution program includes execution programs such as a BB mode, an AT mode, and an RT mode, and the CPU 30a reads out these execution programs to execute the game in each mode. In the AT mode game, the sub reel 15 is rotated simultaneously with the rotation of the first to third reels 14a to 14c. As a result, the CPU 30a functions as first special mode execution means and second special mode execution means.
[0028]
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.
[0029]
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 the 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.
[0030]
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.
[0031]
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.
[0032]
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. For the bell, stop control of the first to third reels 14a to 14c is performed so that a winning is made only when the stop buttons 19a to 19c are operated in a predetermined order.
[0033]
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.
[0034]
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.
[0035]
In addition, the bell patterns constituting the bell are arranged so that the intervals between the bell patterns are within four winning patterns, and if the operation order of the stop buttons 19a to 19c is correct, a prize is won regardless of the operation timing. Thus, stop control of the first to third reels 14a to 14c is performed.
[0036]
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.
[0037]
As shown in FIG. 3, the winning combination determining unit 40 is provided with a plurality of winning combination lottery tables in which random values are grouped according to their sizes. The first winning combination lottery table 60 is a small combination corresponding to a small combination winning pattern in which a random number sampled in a game in the normal mode gives a right to shift to the BB mode, and only a predetermined number of medals are paid out. It is used for replay that gives the right to play the next game with the same number of bets without inserting medals, and for determining which picture belongs to, such as losing that does not cause any wins, that is, winning determination. 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. In addition to the first winning combination lottery table 60, the winning combination determining unit 40 is provided with a replay winning probability table 61 used in the RT mode game.
[0038]
In addition to the first winning combination lottery table, the winning combination determining unit 40 is provided with a winning combination lottery table used in the BB mode and the RB mode in the BB mode. When the winning combination is determined by the winning combination determination unit 40, a winning combination determination signal indicating the determined lose or the type of winning combination is input to the CPU 30a.
[0039]
The RT mode transition lottery unit 41 includes an electronic lottery unit 46, a first transition probability table 47, and a second transition probability table 48. The RT mode transition lottery unit 41 is activated when the BB mode ends. When the RT mode transition lottery unit 41 is activated, the electronic lottery unit 46 samples the random number value, and the sampled random number value is collated with the first transition probability table 47 or the second transition probability table 48. The first transition probability table 47 and the second transition probability table 48 are grouped into a group in which all random numbers generated in the electronic lottery unit 46 are shifted to the RT mode and a group that is not shifted to the RT mode. Thereby, the RT mode transition lottery unit 41 performs RT transition lottery for determining whether or not to shift to the RT mode. In the first transition probability table 47, random number values are grouped so that the transition probability to the RT mode is higher than that in the second transition probability table 48. Then, when the lottery state of the RT transition lottery is a high probability state, the lottery is performed using the first transition probability table 47, and when the lottery state of the RT transition lottery is a low probability state, the second transition probability table 48 is selected. A lottery is performed using.
[0040]
The RT end game number lottery unit 42 is activated when the mode is shifted to the RT mode, and the number of games that can be played in the RT mode is determined by lottery. When the number of games that can be played in the RT mode is determined, a game number determination signal is fed back to the CPU 30a.
[0041]
The RT start game number lottery unit 43 is operated after the end of the BB mode when it is determined to shift to the RT mode. The RT start game number lottery unit 43 determines the number of games from the end of the BB mode to the transition to the RT mode by lottery.
[0042]
The AT mode transition lottery unit 44 will play the bell for the first time when the replay is won in the game in the normal mode and in the game after the end of the BB mode. Won a prize Activated when The AT mode shift lottery unit 44 performs an AT shift lottery for determining whether to shift to the AT mode by lottery. In the AT mode transition lottery unit 44, a plurality of AT transition probability tables having different transition probabilities to the AT mode are provided. When the replay is won and the AT mode shift lottery unit 44 is operated, a two-step AT shift lottery is performed using different AT shift probability tables, and when the two lotteries are won in succession, the mode shifts to the AT mode. Is done.
[0043]
The RT transition probability falling lottery unit 45 is operated for each game in which the lottery state of the RT transition lottery is in a high probability state after the end of the BB mode, and transitions the lottery state of the RT transition lottery from the high probability state to the low probability state. Whether or not is determined by lottery.
[0044]
Whether the replay winning lottery unit 49 performs stop control of the first to third reels 14a to 14c so that the replay can be won when the replay is won in the lottery using the replay winning probability table 51. It is decided by lottery whether or not.
[0045]
The medal hopper 50 pays out a prescribed number of payout medals to the medal tray 20 according to the type of winning combination, or adds the prescribed 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 50.
[0046]
Next, the operation of the slot machine configured as described above will be described. As shown in FIGS. 4-6, when BB mode is complete | finished, it transfers to normal mode, and the lottery state of RT transfer lottery is made into a high probability state.
[0047]
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.
[0048]
At the same time, the electronic lottery unit 39 samples a random number, compares the value with the first winning combination lottery table 60 of the winning combination determination unit 40, determines the type of the lose or winning combination, and the winning combination determination signal is sent to the CPU 30a. Provide feedback. 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.
[0049]
In addition, after the end of the BB mode, during the game period in which the lottery state of the RT transition lottery is in a high probability state, the RT transition probability falling lottery unit 45 is operated each time a game is played. In the RT transition probability falling lottery unit 45, whether or not to shift the lottery state of the RT transition lottery from the high probability state to the low probability state is determined by lottery.
[0050]
In the game after the end of the BB mode, when the player wins the bell for the first time and can win the bell, the AT shift lottery unit 42 is operated and the AT shift lottery is performed. When winning the AT shift lottery, the CPU 30a reads the AT mode execution program from the memory 31 and shifts to the AT mode. When the replay is won in the normal mode game, the AT mode shift lottery unit 42 is operated, and the AT shift lottery is performed twice. At this time, if the AT transition lottery is won twice in succession, the mode is shifted to the AT mode.
[0051]
When BB is won and BB is won, the execution program in the BB mode is read from the ROM area of the memory 31, and the normal mode is shifted to the BB mode. When the mode is shifted to the BB mode, the winning combination lottery table is switched, and the game in the RB introduction mode and the RB mode is performed. In the RB introduction mode, the game is played with 1 to 3 medal bets. In a game in the RB introduction mode, the winning combination for shifting to the RB mode is won, and when the winning combination is won, the mode is switched to the RB mode. 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.
[0052]
When the BB mode ends, the RT mode transition lottery unit 41 is activated. When the lottery state of the RT transfer lottery is a high probability state at the time of BB winning, the random value sampled by the electronic lottery unit 46 is checked against the first transition probability table 47, and the lottery state of the RT transfer lottery at the time of BB winning is In the case of a low probability state, the random value sampled by the electronic lottery unit 46 is checked against the second transition probability table 48.
[0053]
When the RT transfer lottery is won, the RT start game number lottery unit 43 is operated, and the number of games until the RT mode is shifted to is determined by lottery. When the determined number of games have been played, the CPU 30a reads the RT mode execution program from the memory 31 and shifts from the normal mode to the RT mode. When the RT mode is entered, the RT end game number lottery unit 42 is operated, and the number of games that can be played in the RT mode is determined by lottery.
