Description

  The present invention relates to a game hall device that counts predetermined game data based on various game signals output from a plurality of slot machines installed in a game hall, and in particular, estimates the winning timing of a bonus combination that becomes a bonus game. The present invention relates to a playground apparatus.

  In general, a slot machine has a predetermined pattern, number, character, etc. on the outer peripheral surface when a player inserts a game medal (coin) or game ball (pachinko ball) as a game medium and presses a start lever. A plurality of reels (usually three reels) with the symbol of 開始 start rotating, and after rotating at a constant speed, the reels are stopped by pressing the stop button at an arbitrary timing. This is a gaming machine in which a predetermined number of gaming media are paid out according to the combination of symbols.

  In such a slot machine, an internal lottery is performed based on a predetermined lottery probability at the timing of operating the start lever for each game. As a result of internal lottery, each reel is controlled to stop based on the operation timing of the stop button so that the winning content of the current game is determined from a plurality of lottery targets and is stopped and displayed with a combination of symbols corresponding to the winning content It has come to be.

The lottery objects in the internal lottery include a lottery object to which a game value is given to a player by a stop display of a combination of symbols on the corresponding reel, and a lottery that is a lottery object to which no game value is given. A lottery subject to which a game value is given to a player is called a role, and a small number of game media to which a predetermined number of game media are given by a stop display of a combination of symbols on a corresponding reel (hereinafter referred to as winning) ”, A“ re-playing game ”that is not given game media but can be played without inserting game media in the next game, and a bonus game that is a special game state in which a predetermined small role is continuously won with high probability There is a “bonus combination” that is a condition for transition.
The lottery probability that these lottery objects are drawn is usually set so that a lottery occurs frequently, a small combination, a re-playing combination, etc. occur occasionally, and a bonus combination occurs rarely. Therefore, the majority of the gaming state is occupied by normal games in which losers, small roles, and re-playing roles occur, and the player expects to win a bonus role in such normal games, The machine game is progressing.

In the slot machine, if the bonus combination is won, the winning content will be carried over to the next game unless a combination of symbols corresponding to the bonus combination (for example, “7 / 7.7”, hereinafter, bonus symbol) is displayed. It has become.
Such a game segment in which a bonus combination is carried over is called a so-called jackpot flag carry-over, internal hit, etc. (hereinafter referred to as an internal winning game segment in this document), and a special bonus that does not perform an internal lottery of a new bonus combination. It is a game section.
Therefore, using such an internal winning game section, the probability of winning a re-playing role in this internal winning game section (hereinafter referred to as a re-playing role winning probability) is compared with the game section before this game section. Slot machines that vary to either low probability or high probability are prevalent.

  For example, in the game section from the time when the slot machine power is turned on until the bonus combination is won, or after the bonus game is completed until the next bonus combination is won, the winning probability of the re-game combination is low (for example, about 1 / 7.3). In the internal winning game section, the winning probability of the re-gamer is set to a high probability (for example, about 1/3), and the combination of symbols corresponding to the re-gamer is displayed in the internal winning game section. By playing frequently (hereinafter referred to as “re-game winnings”), the player can enjoy the effects (eg, sound and TV effects) until the transition to the bonus game while suppressing the number of game media spent until the bonus symbols are complete. There is a slot machine to let you.

  In addition, a game state referred to as a replay time (RT) in which a state where the winning probability of a re-gamer is high (for example, about 1 / 1.1) continues over a predetermined game section, or the replay time (RT) In addition, it is called Assist Replay Time (ART) that notifies (assist: AT) the combination of symbols corresponding to the internal winning combination (especially the small combination) and the pressing order depending on the display mode of the liquid crystal TV and the lighting mode of the lamp. There are also slot machines having a gaming state (RT or ART function slot machine), and in such a slot machine, a plurality of game sections (for example, low probability, high probability, and In some cases, three game intervals with medium probabilities in between are set.

For example, in such a slot machine, the winning probability of the re-gamer is set to a high probability (for example, about 1 / 1.1) during RT or ART, but in the internal winning game section, the medium probability (for example, , About 1/3), and in a normal game that is a game section other than that, a low probability (for example, about 1 / 7.3) is set.
For this reason, if a bonus combination is won during RT or ART, the winning probability of the re-gamer will change from a high probability to a medium probability, and if the bonus combination is won in normal games, the winning probability of the re-gamer will be low Will vary from medium to medium probability.

In addition, in the game section where the probability of winning a re-playing role such as replay time (RT) or assist / replay time (ART) is high, a random-variable type slot machine that raises the winning probability of a bonus role compared to normal games has appeared. Is also expected.
Thus, in recent slot machines, an internal winning game section, that is, a game section after a bonus combination is won until a bonus symbol is displayed (hereinafter referred to as a bonus game start or bonus winning) is this game section. There is an increasing number of things that change to either a low probability or a high probability compared to the previous game interval.

  By the way, in the game hall, there is a game hall device (for example, a call lamp, a hall computer, etc.) that counts predetermined game data based on various game signals output from a game machine such as a pachinko machine or a slot machine. Such a game field device has, for example, a start signal output every game (in the slot machine, a substitute signal indicating the number of game media inserted) and a big hit signal output during a big hit state or during a bonus game Or, based on the bonus game signal, calculate the probability (hit probability or bonus winning probability) indicating the occurrence frequency of the jackpot or bonus game, and to make the player and the game hall manager understand the characteristics and performance of the gaming machine The calculated probabilities are displayed.

However, in the case of a slot machine, the bonus winning probability is calculated as a value that is different from the bonus winning probability for winning the bonus combination in the internal lottery.
Here, the bonus winning probability is the initial value (zero) of the previous bonus game end or a predetermined initial state (when the slot machine is turned on, when the game room is opened, when the game room is turned on, etc.) Is a calculation probability calculated with the number of games from the next bonus game start to the denominator, and the bonus winning probability is a set probability set for each lottery object in the internal lottery of the slot machine The probability of winning a bonus role.
As described above, in the case of a slot machine, the bonus combination can be carried over until the bonus symbol is displayed, and the bonus game start timing and the winning timing of the bonus combination are different. The bonus winning probability, which is the set probability, was far from the value.
In other words, it is desirable that the calculated bonus winning probability is close to the bonus winning probability in the internal lottery, which is the set probability, but due to the carry-over of the bonus role, the bonus winning probability is actually set even though it is won. In other words, because the bonus symbols are not aligned (this depends exclusively on the skill of the player), there is a probability that a blank game that does not draw the bonus combination is included.
That is, in the conventional game hall device, the bonus winning probability calculated by adding this blank game as the number of games between the bonus games is calculated, so the calculated bonus winning probability is the bonus winning probability of the internal lottery. Did not match (calculated lower than the bonus winning probability of internal lottery), and the game data had low credibility and fluctuated depending on the skill of the player.

  Focusing on the characteristics of such a slot machine, Patent Document 1 discloses an invention of a management device that outputs an internal winning signal related to bonus winning, from a slot machine, and detects and manages this signal. In addition, the store clerk can support bonus winning for players who have difficulty in arranging bonus symbols such as beginners.

JP 2004-208923 A

However, since the signal related to the internal winning is generally not output from the slot machine, it is impossible to identify the internal winning game section from the outside.
Therefore, the inventors of the present invention have the feature of the slot machine that changes the winning probability of the re-gamer in the internal winning game section as described above to either a low probability or a high probability compared to the game section before this game section. In view of the above, the present inventors have arrived at the present invention for estimating the winning timing of a bonus combination from the history of re-game winnings.

  That is, the present invention has been considered in view of the above circumstances, and detects a re-game win based on a predetermined game signal output from the slot machine, and also from the history of the re-game win and the start of the bonus game. The game hall device that estimates the winning timing of the bonus combination and calculates the estimated bonus winning probability excluding the subsequent game sections, thereby calculating the estimated bonus winning probability that is game data close to the bonus winning probability in the internal lottery The purpose is to provide.

  In order to achieve the above object, the game hall device of the present invention is a lottery object for internal lottery in which a bonus combination that becomes a predetermined bonus game and a re-playing combination that can be played next time without inserting a game medium are performed for each game. In addition, a plurality of game sections having different winning probabilities for re-playing roles are set, and the winning probability of re-playing roles in the internal winning game section after the bonus winning is started until the bonus game is started is determined as the internal winning game. A game field device that aggregates game data based on a predetermined game signal that is output from the slot machine, with a slot machine that changes to either a high probability or a low probability compared to the previous game section. And detecting the start of the bonus game based on a bonus game signal output from the slot machine during the bonus game. -Reuse game start detection means, re-game winning detection means for detecting a re-game winning based on a predetermined game signal output from the slot machine, and re-game for storing this detection result as a re-game winning prize history Winning history storage means, winning timing estimation means for estimating the winning timing of the bonus combination related to the bonus game based on the re-playing role winning history before the start of the bonus game, the end of the previous bonus game or a predetermined initial state And an estimated bonus winning probability calculating means for calculating an estimated bonus winning probability with a denominator of the number of games from the estimated time until the winning timing.

  According to the present invention, an estimated bonus winning probability close to the bonus winning probability in the internal lottery can be calculated even in a slot machine that does not output an internal winning signal.

  Hereinafter, preferred embodiments of a game arcade apparatus according to the present invention will be described with reference to the drawings.

First, a game hall system provided with the game hall apparatus of the present invention will be described with reference to FIGS.
As shown in each drawing, the game hall system 1 includes a plurality of slot machines 10 using medals as game media, a call lamp 20 provided for each slot machine 10, and a stand computer 30 connected to the call lamp 20. And an island computer 40 provided in the gaming machine island unit in which the slot machine 10 is installed, and a hall computer 50 connected to the island computer 40, which are connected to a predetermined network (for example, a local area network). A predetermined game signal from the slot machine 10 and game data generated by each device are connected via a network).

  The calling lamp 20 lights or flashes lamps such as light bulbs and LEDs to notify the player of bonus winnings and the like, and also provides game data related to the game such as the number of bonuses, the number of games between bonuses, and the estimated bonus winning probability. A display device for displaying. Further, the calling lamp 20 receives the game signal output from the slot machine 10 and transmits it to the computer 30, and receives the game data compiled by the computer 30 and displays the game data. It is configured.

The stand computer 30 and the island computer 40 are information relay processing devices, respectively, and exchange predetermined game data with the hall computer 50.
The hall computer 50 is an information processing device that counts predetermined game data. The hall computer 50 collects the game data of each slot machine 10 counted by the stand computer 30 and collects the slot machine 10 for each slot machine 10, each slot machine 10 model, Game data (for example, total number of inputs, total number of payouts, estimated bonus winning probability, sales, gross profit, divide, etc.) is aggregated in units such as each gaming machine island and the entire game hall.

The slot machine 10 has a bonus combination for a bonus game, a re-playing combination that can be played next time without inserting medals, a small combination to which a predetermined number (for example, 10) of medals are paid out, and a losing function. A plurality of lottery targets are set, and each lottery target is configured to perform an internal lottery to determine the winning content of the current game with a predetermined lottery probability from among these lottery targets, A plurality of different game segments are set.
In particular, the winning probability of a re-playing player in the internal winning game section after the bonus winning combination is started until the bonus game is started fluctuates to either a high probability or a low probability compared to the game section before this internal winning game section. Is set to be.
Specifically, in the game hall system 1 of the present embodiment, a normal type (so-called A type) slot machine, a slot machine equipped with an ART (assist replay time) function, each having different variations, and A slot machine with a bonus probability variation function is installed.

In the normal type slot machine 10, the winning probability of the re-gamer in the internal winning game section is set higher than the game section before the internal winning game section, and is set to a uniform value except for the internal winning game section. ing.
The slot machine 10 equipped with the ART function is set so as to have a replay high probability game section in which the winning probability of the regame player is set higher than the winning probability of the regame player in the internal winning game section.
The slot machine 10 equipped with the bonus probability variation function has a bonus game winning probability and a re-playing game winning probability from the end of the bonus game to a predetermined game section (in this embodiment, until the next bonus winning game, It is set so as to have a probability variation game section that can be varied to either a predetermined low probability or a high probability with a higher probability.

As shown in FIG. 2, these slot machines 10 have, as a predetermined game signal, a medal insertion signal indicating the number of medals inserted into the game, and the number of medals paid out according to the winning of the game. A medal payout signal, a bonus signal indicating a bonus gaming state (bonus 1 signal, bonus 2 signal), and the like are output.
As shown in FIG. 4A, the medal insertion signal is output as a group of pulse waveforms indicating the number corresponding to the number of insertions every time a slot machine game progresses.
In the slot machine 10, since the interval (tn) between the games is always set to be at least a predetermined time (tmin), a group of pulse waveforms output within a predetermined time (tmin) is 1 By accumulating each game as a game, for example, the number of games between bonus games can be totaled.

In addition, the medal payout signal is output as a group of pulse waveforms indicating a number corresponding to the number of payouts for each game won in the small combination or replaying combination.
The slot machine 10 according to the present embodiment detects a game in which the number of pulses related to the medal insertion signal and the number of pulses related to the medal payout signal are the same because the small combination in which the number of insertions is equal to the number of payouts is not set. By doing so, it is possible to specify a replay winning prize.
The bonus signal is a state signal that is turned on during a bonus game that changes from off to on when the bonus game starts and changes from on to off when the bonus game ends.
In this embodiment, two types of bonus combinations are set according to the difference in the number of medals that can be acquired during the bonus game, and a bonus signal (bonus 1 signal or bonus 2 signal) corresponding to the winning bonus combination is output. .

The stand computer 30 operates as a game hall apparatus according to the present invention, totals game data based on a predetermined game signal output from the slot machine 10, and collects the totaled game data via the island computer 40. 50 and the call lamp 20 are transmitted.
The stand computer 30 is provided for one or more slot machines 10 and includes a communication unit 31, a storage unit 32, and a control unit 33, as shown in FIG.

The communication unit 31 is connected to the calling lamp 20 and the island computer 40, and transmits / receives predetermined game data to / from the calling lamp 20 and the island computer 40.
For example, the communication unit 31 receives game signals such as a medal insertion signal, a medal payout signal, and a bonus signal output from the slot machine 10. In addition, the communication unit 31 transmits game data generated based on the game signal to the calling lamp 20 and the hall computer 50. Note that the communication unit 31 can also directly receive the game signal output from the slot machine 10 from the slot machine 10 without using the call lamp 20.

The storage unit 32 operates as a re-game winning history storage unit according to the present invention, and programs and data for executing various functions of the computer 30, data indicated by game signals received by the communication unit 31, which will be described later The threshold value and the fluctuation timing are stored. The data stored in the storage unit 32 includes history data 32a, game data 32b, and the like. Hereinafter, the history data 32a will be described with reference to FIG. 4, and the game data 32b will be described later.
As shown in FIG. 4, the history data 32a stores information related to games over the past 50 games.
The history data 32a is generated based on the game signal as shown in FIG. 4A received by the communication unit 31, and as shown in FIG. 4B to FIG. “Number”, “Number of payouts”, “Re-game winning history”, “Number of games between bonuses”, “Re-game winning probability history PA”, and “Re-game winning probability history PB” are items for the past 50 games for each game. It is a database that records.

“Game” indicates a number for identifying games from one game before to 50 games before.
“Number of insertions” indicates the number of medals inserted in the game specified from the number of pulses included in the medal insertion signal, and “Number of payouts” indicates the number of pulses specified in the medal payout signal. Indicates the number of medals to be paid out.
For example, from the game signals before 50 games to 48 games before shown in FIG. 4A, the “number of inputs” from 50 games to 48 games before is “3”, and the “number of payouts” is 50 games before. Can be identified as “0”, “10” before 49 games, and “3” before 48 games.
The “replay winning history R” indicates a history of presence / absence of a replay winning for each game, and “1” indicates “winning” and “0” indicates “no winning”. From the game signals before 50 games to 48 games before, 48 games before is “winning”, that is, “1”. Such a determination as to whether or not there is a re-game winning is performed by the control unit 33, and as described above, only a game with the same number of “inputs” and “number of payouts” is determined as having a re-game winning, Otherwise, it is determined that there is no re-game winning (re-play winning detection means).

“Number of games between bonuses” indicates the number of games from an initial state such as power-on of the slot machine 10 or from the end of the previous bonus game, and the control unit 33 sets a group of pulse waveforms as one game as a group of pulse waveforms. It is the value accumulated. By accumulating in this way for each game, the value of “number of games between bonuses” when the bonus game is started indicates the number of games from the end of the previous bonus game to the start of the current bonus game.
Note that the end of the bonus game can be specified by the control unit 33 detecting the timing of change from ON to OFF in the bonus signal.

The “replay winning probability history PA” indicates the winning probabilities of replaying players for the past 50 games from the current game up to a predetermined number of games in the past. In the example shown in FIG. The winning probability of the re-playing role of the current game is calculated every time one game progresses from the “re-play winning history R” for a total of five games from the game to the past four games.
For example, if one game before is the current game, the winning probability of the re-gamer from one game to five games before is “0” (4) before the “re-game winning history R” between the games. No), and all other cases are “1” (with a prize), so “4/5” is calculated.

“Re-game winning probability history PB” shows the winning probabilities of the re-gamer up to each game that has gone back one game from the current game for the past 50 games. In the example shown in FIG. In the “regame winning history R”, if one game before is the current game, the probability of winning a regame player up to each of the past 49 games is calculated each time one game progresses from one game before.
For example, the winning probability of the re-gamer one game before is “1/1” because it is “1” in the “re-game winning history R”, and the winning probability of the re-gamer from one game before to two games before Is “2/2” because both games are “1” in the “Regame Winning History R”, and the winning probabilities for the replaying roles from 1 game before to 3 games before are “Regame Winning History R”. Since all three games are “1”, “3/3” is calculated every time one game progresses, the winning probabilities of the re-gamer up to each game that goes back one game at a time.
The calculation of the winning probability of the replay in the “replay winning probability history PA” and the “replay winning probability history PB” is executed by the control unit 33 every time the slot machine game progresses (replaying) Winning probability calculation means).

The control unit 33 is configured by a computer including a CPU, and reads and executes a program stored in the storage unit 32, thereby executing a bonus game start detection unit, a re-game winning detection unit, a re-game winning probability calculation unit, a win It operates as timing estimation means and estimated bonus winning probability calculation means.
For example, the control unit 33 specifies the number of inserted medals and the number of paid-out medals from the received game signal, and stores them in the storage unit 32 for each game.
Further, the control unit 33 operates as a re-game winning detection means, determines that a game having the same number of insertions and payouts has a re-game winning, and determines that there is no re-game winning, and determines the result as “re-play winning history”. R "is stored in the storage unit 32 for each game.
Further, the control unit 33 operates as a re-game winning probability calculation means, and from the “re-play winning history R”, the re-game winning probability (“re-game winning probability history PA”, “re-game winning probability history PB”). Is calculated for each game and stored in the storage unit 32.

Further, the control unit 33 operates as a bonus game start detection unit, detects the timing at which the bonus signal changes from off to on, thereby detecting the start of the bonus game and also detects the timing at which the bonus signal changes from on to off. By doing so, the end of the bonus game is detected.
Further, the control unit 33 operates as a winning timing estimation unit, and estimates the winning timing of the bonus combination related to the bonus game based on the re-game winning history R (including the re-game winning probability history) before the bonus game is started. To do. Hereinafter, the operation as the winning timing estimation means of the control unit 33 will be described with reference to FIGS.

First, the operation as the winning timing estimation means of the control unit 33 in the case where the normal type slot machine 10 is targeted for aggregation will be described.
In the normal type slot machine 10, the winning probability of the re-gamer in the internal winning game section is set higher than the game section before the internal winning game section, and is set to a uniform value except for the internal winning game section. ing.

  Specifically, in the normal type slot machine 10 according to the present embodiment, there are two game sections having different winning probabilities of re-game players, and the winning probability of the re-game players in the internal winning game section is high (1 / 3), and the winning probability of the re-gamer in the game section other than the internal winning game section is set to a low probability (1 / 7.3). In other words, the winning probability of the re-gamer in the internal winning game section is set higher than that in the game section before the internal winning game section. In addition, the winning probability of the re-gamer during the bonus game is usually set to almost zero, and including the winning probability of the re-gamer during the bonus game, strictly speaking, three games with different winning probabilities of the re-gamer are included. Although there are sections, in the following description (including the slot machine equipped with the ART function and bonus probability variation function), the winning probability of the re-gamer in the bonus game is treated as a low probability (1 / 7.3) for convenience.

In such a normal type slot machine 10, as shown in the time chart 1 shown in FIG. 5A, when a bonus combination is won (A: 8 games before), a re-playing combination is started from the next game after the winning game. The winning probability will change from a low probability (1 / 7.3) to a high probability (1/3), and after that, the high probability (1/3) continues until the game (B) that wins the bonus game. It becomes a winning game section.
FIG. 5B shows actual measurement data when the game is progressed in the slot machine 10 in which the winning probability of the re-gamer fluctuates according to the time chart 1, and the winning probability of the re-gamer in the internal winning game section. The replay from the previous game to the 15th game before winning the bonus game when the winning probability of the replaying role in the game section before the internal winning game section is 1 / 7.3. FIG. 5 (c) is a graph showing the winning history R, and FIG. 5 (c) is a transition graph A representing the replay winning probability history PA calculated from the replay winning history R and its transition. FIG. It is the transition graph B showing the transition of the re-game winning probability history PB calculated from the re-game winning history R.

The control unit 33 determines the winning timing of the bonus combination by any one of the following three estimation methods from the replay winning history R (including the replay winning probability histories PA and PB). Is estimated.
In the first estimation method, as shown in FIG. 5B, when the control unit 33 detects the start of the bonus game from the change of the bonus signal from OFF to ON, it continues to the re-gamer until the bonus game starts. When winning a prize, it is estimated that the game immediately before the winning of a series of re-playing roles starts is determined as the bonus winning timing.

Specifically, in the first estimation method, in the re-game winning history R, when winning a re-game player continuously (for example, twice or more) until the start of the bonus game, the one before the bonus game is won. In this estimation method, a process for searching for a game without a re-game prize is executed while going back to the past game one game at a time, and a game without a re-game prize searched first is estimated as a winning game of a bonus role. is there.
For example, in the re-game winning history R shown in FIG. 5B, from 1 game before the start of bonus game to 3 games before, there is a re-game winning ("1"), and 4 games before. Since there is no re-game win for the first time (“0”), 4 games before the start of a series of re-game wins are estimated as the winning timing of the bonus combination (estimation 1).
In such an estimation method, the winning probability of the re-gamer in the internal winning game section is close to 1, and the difference from the winning probability (1 / 7.3) of the re-gamer in the game section before the internal winning game section is This is a useful estimation method at certain times.

As shown in FIGS. 5 (c) and 5 (d), the second estimation method and the third estimation method have a predetermined threshold between the games before and after the bonus game probabilities before the bonus game starts. This is an estimation method for estimating the previous game that has fluctuated over the period as the bonus combination winning timing.
Specifically, in the second estimation method, when the control unit 33 detects the start of the bonus game from the change of the bonus signal from off to on, the control unit 33 starts one of the bonus games in the re-game winning probability history PA. Going back to the past game one game at a time from the previous game, the game is searched for a game where the winning probability of the re-gamer is greater than the threshold value A (1/5) and below the threshold value A (1/5) The first game that falls below the threshold A (1/5) is estimated as the bonus combination winning timing.

For example, in the replay winning probability history PA shown in FIG. 5 (c), the winning probabilities of replaying players all have a threshold A (1/5) from one game before the start of the bonus game to seven games before. Since this value exceeds the threshold A (1/5) for the first time before 8 games, it fluctuates across the predetermined threshold A between the games before and after 8 games and before and after 7 games. Therefore, the previous game, which is 8 games before, is estimated as the bonus winning timing (estimation 2).
Since the replay winning probability history PA is a value reflecting the winning probability of the replaying player over the past five games, it is difficult to reliably match the winning timing of the bonus combination, but as shown in the transition graph A In addition, since the winning timing of the bonus combination can be estimated from the change in the winning probability of the re-playing combination, it is possible to extract a game that is almost close to the winning timing.

  In the third estimation method, when the control unit 33 detects the start of the bonus game from the change of the bonus signal from OFF to ON, the control unit 33 starts from the game immediately before winning the bonus game in the replay winning probability history PB. As each game goes back to the past game, a search is made for a game in which the winning probability of the re-playing role is lower than the threshold value B (60%) and below the threshold value B (60%), and the first game that falls below the bonus game Estimate the winning timing.

For example, in the re-game winning probability history PB shown in FIG. 5D, the winning probability of the re-gamer is all equal to or greater than the threshold B (60%) from 1 game before the start of the bonus game to 8 games before. Yes, since it is below the threshold B (60%) for the first time before 9 games, it is assumed that the game has fluctuated across the predetermined threshold B between the games before and after the 9 games and before the 8 games. Nine games before the game are estimated as the bonus winning timing (estimation 3).
The replay winning probability history PB is a value that reflects the winning probabilities of the replaying players from each game to each game that has been traced back by one game in the past, so it is difficult to reliably match the winning timing of the bonus combination However, as shown in the transition graph B, since the winning timing of the bonus combination can be estimated from the transition of the change in the winning probability of the re-playing combination, it is possible to extract a game that is almost close to the winning timing.

In addition, the winning timing of the bonus combination estimated by the second estimation method tends to shift to the bonus winning side, and the winning timing of the bonus combination estimated by the third estimation method tends to shift from the bonus winning to the past side. In addition to grasping these tendencies from a large number of actually measured data, the number of games deviating can be acquired as a correction value (experience value), and the winning combination of the bonus combination estimated by each estimation method can be corrected by this correction value.
For example, in the third estimation method, the correction value is set to one game, and one game later than the estimated game of the bonus combination winning timing can be estimated as the bonus combination winning timing.

Moreover, the control part 33 can also estimate the winning timing of the bonus combination by the fourth estimation method shown below.
Specifically, in the first to third estimation methods described above, after the start of the bonus game is detected, each history (R, PA, PB) is searched retroactively, and the bonus combination winning timing is determined. However, in the fourth estimation method, every time one game progresses, the fluctuation timing of the winning probability of the re-gamer is estimated from each history (R, PA, PB), and the estimated game is used as the fluctuation timing. This is a method in which the change timing stored in the storage unit 32 in advance and simultaneously with the detection of the start of the bonus game is estimated as the winning timing of the bonus combination.

FIG. 6 is a diagram in which FIGS. 5A to 5C are further expanded several games to the past side.
In the fourth estimation method, each time one game progresses, the control unit 33 uses the re-game winning probability calculated in the current game and the re-game winning probability of the previous game in the re-game winning probability history PA. In comparison, when the winning probability of the re-gamer calculated in the current game fluctuates across the threshold A with respect to the winning probability of the re-gamer of the previous game, the previous game is stored in the storage unit 32 as the change timing. Execute the process. Each time such a variation is detected, the variation timing is overwritten and stored, and at the same time as the start of the bonus game is detected, the stored variation timing is estimated to be the bonus combination winning timing. The previous game stored in the storage unit 32 as the variation timing is a “number of games between bonuses” indicating the number of games since the power-on of the slot machine 10 or the end of the previous bonus game (FIG. 4B). )reference).

For example, in the example shown in FIG. 6, if 15 games before this game is the current game, the control unit 33 determines that the winning probability (2/5) of the re-gamer calculated in the current game is 16 games before the previous game. It is considered that the game player's winning probability (1/5) has fluctuated across the threshold A (1/5), and 16 games before is stored in the storage unit 32 as the fluctuation timing (1).
Further, assuming that the game progresses and seven games before the current game, the control unit 33 determines that the winning probability (2/5) of the re-gamer calculated in the current game is 8 games before the previous game. The winning probability (1/5) is assumed to have fluctuated across the threshold A (1/5), and the previous eight games are overwritten and stored in the storage unit 32 as a new fluctuation timing (2).
Then, the control unit 33 estimates that the bonus game winning timing is 8 games before (variation timing 2) stored in the storage unit 32 in the current game where the start of the bonus game is detected.
As a result, since the winning timing of the bonus combination can be estimated in real time as the game progresses, the estimation speed can be increased.
The variation timing (1) temporarily stored in the storage unit 32 is simply due to the fact that the replay winnings are accidentally concentrated, but at the time when the variation timing (1) is stored, Although it is unclear whether it is accidental concentration or the bonus combination winning timing, it is necessary to remember as long as there is a possibility of the bonus combination winning timing. And, when such variation timing occurs, it is overwritten and stored, so that when the start of the bonus game is detected, the variation timing that is finally stored is the winning timing of the bonus combination related to the bonus winning It can be estimated that.

In the fourth estimation method described above, the variation timing is detected using the re-game winning probability history PA, but the re-game winning probability history PB can also be used.
The winning combination winning timing can also be estimated by the following estimation method (fifth estimation method) in which the search direction is reversed in the first estimation method.
Specifically, in the replay winning history R, the previous game (the number of games between bonuses) when the current game has a replay win and the previous game also has a replay win is stored, and in the progress of the subsequent game, When there is a regame winning, the stored game is held without being updated, and when a game without a replay winning appears, the stored previous game is deleted. Thereafter, in the game in which the start of the bonus game is detected, the previous game stored in the storage unit 32 can be estimated as the bonus combination winning timing.
Moreover, the threshold value in the second to fourth estimation methods can be set to an arbitrary value according to the winning probability of the re-gamer.

The control unit 33 operates as the estimated bonus winning probability calculation means as follows.
When the control portion 33 estimates the winning timing of the bonus combination by the first to fourth estimation methods described above, the estimated bonus winning is performed by excluding the number of games from the game immediately after the estimated game until the bonus game starts. Probability is calculated.
Specifically, the control unit 33 calculates the estimated bonus winning probability based on the flowchart related to the estimated bonus winning probability calculating process shown in FIG. Hereinafter, the estimated bonus winning probability calculation process will be described.

As shown in FIG. 7, when the control unit 33 detects the start of the bonus game, the control unit 33 calculates the bonus interval in the current game (the bonus game start game) from the “number of games between bonuses” in the history data 32a shown in FIG. The number of games (for example, 299 + 1 = 300) is acquired (S10), and the bonus winning timing is estimated by any one of the first to fourth estimation methods described above (S11). Next, the number of internal winning games is calculated from the estimated game (S12). For example, in the first estimation method, as shown in FIG. 5B, the number of games (7 games) from the game immediately after the estimated 1 game to the start of the bonus game is calculated. Then, the number of internal winning games is subtracted from the number of games between bonuses (for example, 300-7 = 293) (S13), and this is used as a denominator and an estimated bonus winning probability (for example, 1/293) with 1 as the numerator. Calculate (S14). That is, an estimated bonus winning probability is calculated using the number of games from the end of the previous bonus game or a predetermined initial state to the estimated winning timing as the denominator. Then, the control unit 33 transmits the estimated bonus winning probability calculated together with other game data to the calling lamp 20 and the hall computer 50 via the communication unit 31.
The estimated bonus winning probability calculated in this way is a value based on the estimated timing related to winning the bonus combination, and can be a value closer to the bonus winning probability than the conventional bonus winning probability. Credibility is improved.

Here, the game data tabulated by the control unit 33 will be described with reference to FIG.
At each end of the bonus game, the control unit 33 calculates game data related to the bonus game of each item shown in FIG. 8 in addition to the calculation of the estimated bonus winning probability as described above, and stores these as game data 32b. To remember.
For example, “bonus game NO” numbered in the order of occurrence of bonus games, “insertion total” indicating the total number of inputs during the bonus game, “payout total” indicating the total number of payouts during the bonus game, bonus game end The “number of games between bonuses” (corresponding to the “number of games between bonuses” in FIG. 4B) indicating the number of games from the first to the next bonus game start, the calculated “number of internal winning games”, and the number of games between bonuses as denominators The “bonus winning probability” indicating the conventional bonus winning probability, the “estimated bonus lottery probability” excluding the number of internal winning games, the “estimated synthetic probability” totaling the estimated bonus winning probability, and the like are calculated. The information is stored in the storage unit 32 as 32 b and transmitted to the calling lamp 20 and the hall computer 50.
The call lamp 20 and the hall computer 50 store these in their respective storage units. For example, the call lamp 20 displays the estimated bonus winning probability, so that the player can win a bonus combination more than before. Provide accurate game data close to probability.

Next, the operation of the control unit 33 as the winning timing estimation means when the ART function-equipped type slot machine 10 is the target of aggregation will be described.
In the ART function-equipped type slot machine 10, the re-game winning probability is set so that the re-game winning probability is set higher than the winning probability of the re-game player in the internal winning game interval.

  Specifically, in the slot machine 10 of the ART function-equipped type according to the present embodiment, there are three game sections having different winning probabilities of re-players, and in the game section in the ART (hereinafter referred to as a high probability game section). The winning probability is set to a high probability (1 / 1.1), the winning probability of the re-gamer in the internal winning game section is set to a medium probability (1/3), and other game sections (hereinafter referred to as low probability games). The winning probability of the re-gamer in the section) is set to a low probability (1 / 7.3). That is, the winning probability of the re-gamer in the game section (high probability game section) in ART is set higher than the winning probability of the re-gamer in the internal winning game section.

In such an ART function-equipped type slot machine 10, a bonus combination lottery is also performed during the ART. Therefore, as shown in the time chart 3 of FIG. And a winning pattern 2 for winning a bonus combination in the high-probability game section.
Specifically, the winning pattern 1 is that when a bonus combination is won in a low-probability game section (A1), the winning probability of the re-playing combination from the next game after the winning game is low (1 / 7.3). The pattern changes to a medium probability (1/3), and then the medium probability (1/3) continues until the game (B1) that wins the bonus game. The winning pattern 2 is a predetermined timing S (bonus game end or If you win a bonus role during an ART that entered in a specific small role prize (A2), the winning probability of the re-playing role from the next game after the winning game will be high (1 / 1.1) to medium probability (1 / 1.1) 1/3), and then the medium probability (1/3) continues until the game (B2) for winning the bonus game.
In the present embodiment, the control unit 33 estimates the winning timings in the winning patterns 1 and 2 based on the re-game winning prize probability history PA as follows.

FIG. 10 and FIG. 11 are explanatory diagrams for explaining the estimation method of the winning timing in the winning pattern 1 and the winning pattern 2, respectively. In this embodiment, the winning timing is estimated by the above-described fourth estimating method. And
As shown in each figure, the replay winning probability history PA according to the present embodiment indicates the winning probability of the replaying player of the current game from the replay winning history R for a total of seven games from the current game to the past six games. It is calculated every time the game progresses. In the replay winning probability history PA described above, the winning probabilities for the replaying roles between the five games are calculated. However, in the slot machine 10 to be counted in the present embodiment, a large probability is obtained between the low probability, the medium probability, and the high probability. This is because, since there is no difference, it is necessary to observe the transition of the winning probability of the re-gamer over a long game section in order to capture the change in the winning probability of the re-gamer.

Each time one game progresses, the control unit 33 compares the winning probability of the re-gamer calculated in the current game with the winning probability of the re-gamer in the previous game in the re-game winning probability history PA, and calculates the current game. When the winning probability of the re-playing player who has been played fluctuates over the threshold value a or the threshold value b with respect to the winning probability of the re-playing player of the previous game, the change timing for storing the previous game in the storage unit 32 as the change timing Perform storage processing.
At this time, the previous game in which the threshold value a (2.1 / 7 = 0.3) is straddled from the low probability side to the high probability side is stored as the high fluctuation timing, and the threshold value b (5.6 / 7 = 0.8) is stored as the low fluctuation timing in the previous game straddling the high probability side to the low probability side. Each time such a change is detected, the high and low fluctuation timings are overwritten and stored, and at the same time as the start of the bonus game is detected, the stored fluctuation timing is estimated as the winning timing of the bonus combination.
Further, at this time, the control unit 33 executes a winning game state estimation process for estimating a gaming state (probability state) at the time of winning the bonus combination.
Specifically, if the stored fluctuation timing is a high fluctuation timing, the control unit 33 estimates that the bonus combination related to the bonus game is won in the low probability game section, and the stored fluctuation timing is low fluctuation. If it is timing, it is estimated that the bonus combination related to the bonus game is won in the high probability game section.

For example, in the example illustrated in FIG. 10, if the current game is 4 games before the start of the bonus game, the control unit 33 indicates that the winning probability (3/7) of the re-gamer calculated in the current game is the previous game. It is assumed that the winning probability (2/7) of the re-game player before 5 games fluctuates across the threshold value a, and the time before 5 games is stored in the storage unit 32 as the high fluctuation timing 1.
Then, the control unit 33 estimates that the bonus game winning timing is five games before (high fluctuation timing 1) stored in the storage unit 32 in the current game (B1) in which the start of the bonus game is detected.
Furthermore, since the variation timing stored in the storage unit 32 at the start of the bonus game is a high variation timing, the control unit 33 wins the bonus combination related to the bonus game as a bonus combination in the low probability game section. Presumed to be pattern 1.
The reason for this estimation is that in the slot machine 10 according to the present embodiment, the bonus game is started after the threshold value a (2.1 / 7) is straddled from the low probability side to the high probability side. This is because there is no possibility other than winning pattern 1 in which a bonus combination is won in the low-probability game section.

In the example shown in FIG. 11, if the current game is 16 games before the start of the bonus game, the control unit 33 has the winning probability (3/7) of the re-gamer calculated in the current game as the previous game. It is assumed that the winning probability (2/7) of the re-game player before 17 games fluctuates across the threshold value a, and the 17th game before is stored in the storage unit 32 as the high fluctuation timing 1.
Further, assuming that the current game is 8 games before the game progresses and the bonus game starts, the control unit 33 has a 9th game in which the winning probability (5/7) of the re-gamer calculated in the current game is the previous game. It is assumed that the previous regame winning prize probability (6/7) has fluctuated across the threshold value b, and the previous nine games are overwritten and stored in the storage unit 32 as a new low fluctuation timing 1.
Then, the control unit 33 estimates that the 9th game before (low fluctuation timing 1) stored in the storage unit 32 is the winning timing of the bonus combination in the current game (B2) in which the start of the bonus game is detected.
Furthermore, since the variation timing stored in the storage unit 32 at the start of the bonus game is the low variation timing, the control unit 33 wins the bonus combination related to the bonus game as a bonus combination in the high probability game section. Presumed to be pattern 2.
This is because in the slot machine 10 according to the present embodiment, the bonus game is started after the threshold value b (5.6 / 7) is straddled from the high probability side to the low probability side. This is because there can be no other than winning pattern 2 for winning the bonus combination.

As described above, even when the slot machine 10 having three game sections having different winning probabilities of re-game players is to be counted, the winning timing of the bonus player is estimated in real time from the transition of the winning probabilities of the re-player players. Since it is possible to estimate not only the gaming state at the time of winning the bonus combination, but also the gaming state of the estimated bonus winning probability calculated can be classified.
The operation of the control unit 33 as described above is executed based on the flowcharts shown in FIGS. FIG. 12 is a flowchart showing the variation timing storage process, and FIG. 13 is a flowchart showing the winning game state estimation process.
Hereinafter, the variation timing storage process and the winning game state estimation process will be described with reference to each flowchart.

The variation timing storage process compares the winning probability of the re-gamer calculated in the current game with the winning probability of the re-gamer of the previous game in the re-game winning probability history PA every time one game progresses. It is determined whether or not the calculated winning probability of the re-gamer has fluctuated across the threshold value a or the threshold value b with respect to the winning probability of the re-gamer of the previous game (S20).
When it fluctuates across (S20-Yes), it is determined whether or not the threshold value a is straddled from the low probability side to the high probability side (S21). When it is determined that the threshold value a is straddled from the low probability side to the high probability side (S21-Yes), the previous game is stored in the storage unit 32 as the high fluctuation timing (S22).
On the other hand, if the answer is No in S21, it is then determined whether or not the threshold value b is straddled from the high probability side to the low probability side (S23). When it is determined that the threshold value b has crossed from the high probability side to the low probability side (S23-Yes), the previous game is stored in the storage unit 32 as the low variation timing (S24).
If the answer is No in S23, the process ends because the timing does not correspond to either winning pattern 1 or winning pattern 2.
By executing such a process every time one game progresses, the winning timing of the bonus combination related to the bonus game can be estimated in real time simultaneously with the detection of the subsequent start of the bonus game.

Next, the winning game state estimation process is a process executed after the start of the bonus game is detected, and the control unit 33 acquires the variation timing stored in the storage unit 32 at the start of the bonus game. (S30) It is determined whether or not the acquired fluctuation timing is a low fluctuation timing (S31). When it is determined that the timing is low (S31-Yes), the control unit 33 assumes that the bonus combination related to the bonus game is won in the high-probability game section, and the estimated bonus winning probability is calculated in the above-described estimated bonus winning probability calculation process. Is calculated as the estimated bonus winning probability in the high-probability game section (S32).
On the other hand, when it is determined that the timing is not the low variation timing (S31-No), the control unit 33 regards the acquired variation timing as the high variation timing, and the bonus combination related to the bonus game is won in the low probability game section. In the above-described estimated bonus winning probability calculation process, the estimated bonus winning probability is calculated as the estimated bonus winning probability in the low-probability game section (S33).

Here, the game data when the slot machine 10 equipped with the ART function and the bonus probability variation function is set as a target of aggregation will be described with reference to FIG.
The game data 32b shown in FIG. 16 includes game data obtained by adding “low probability estimated bonus winning probability”, “high probability estimated bonus winning probability”, and “ART” as new items to the game data already shown in FIG. It has become.
“Low probability estimated bonus winning probability” indicates the estimated bonus winning probability of the bonus game in which the game section at the time of winning the bonus role is estimated as the low probability game section in the above-described gaming state estimation process. “Winning probability” indicates the estimated bonus winning probability of the bonus game in which the game section at the time of winning the bonus role is estimated to be a high-probability game section, and “ART” indicates that the gaming state at the time of winning the bonus role is a high-probability game section This is an item to be distinguished by attaching a predetermined mark (for example, star) to the bonus game made.

The control unit 33 classifies the estimated bonus winning probability calculated in the estimated bonus winning probability calculating process for each gaming state at the time of winning the bonus role estimated in the winning gaming state estimating process, and the gaming state at the time of winning the bonus role is low. The estimated bonus winning probability related to the bonus game estimated as the probability game section is stored in the item of “low probability estimated bonus winning probability”, and the gaming state at the time of winning the bonus role is stored in the bonus game estimated as the high probability game section. The estimated bonus winning probability is stored in the item “high probability estimated bonus winning probability”.
For example, the bonus game related to “Bonus Game No. 1” is estimated to be a bonus game won in the bonus combination in the low probability game section, and the estimated bonus winning probability calculated in the estimated bonus winning probability calculation process is “ It is stored in the item “low probability estimated bonus winning probability”. Further, the bonus game related to “Bonus Game No. 2” is estimated to be a bonus game won in the bonus role in the high probability game section, and the estimated bonus winning probability calculated in the estimated bonus winning probability calculation process is “ In addition to being stored in the item “high probability estimated bonus winning probability”, “ART” includes a predetermined mark (for example, indicating that the gaming state at the time of winning the bonus role is a bonus game estimated as a high probability game section) An asterisk) is attached and stored.
Then, the control unit 33 transmits the game data 32b to the calling lamp 20 and the hall computer 50. As a result, the calling lamp 20 and the hall computer 50 may display the estimated bonus winning probability for each game section or display only one of the game sections (for example, the low probability estimated bonus winning probability). it can.

Next, the operation as the winning timing estimation means of the control unit 33 in the case where the slot machine 10 equipped with the bonus probability variation function is set as an aggregation target will be described.
In the slot machine 10 of the bonus probability variation function-equipped type, it is set to have a replay high probability game section in which the winning probability of the replaying player is set higher than the winning probability of the replaying player in the internal winning game section, This replay high probability game section is a probability varying game section in which the winning combination of bonus combination is set higher than the other game sections at the same time.

Specifically, in the slot machine 10 of the bonus probability variation function-equipped type according to the present embodiment, there are three game segments having different winning probabilities of re-players, and the game segment in which the bonus probability varies (hereinafter, a high probability game). The winning probability of the re-gamer in the section) is set to a high probability (1 / 1.1), the winning probability of the re-gamer in the internal winning game section is set to a medium probability (1/3), The winning probability of the re-gamer in the game section (hereinafter referred to as the low probability game section) is set to a low probability (1 / 7.3). That is, the winning probability of the re-gamer in the game section in which the bonus probability is changing is set higher than the winning probability of the re-gamer in the internal winning game section.
In the high-probability game section (during bonus probability fluctuation), the winning probability of bonus combination is set higher than other game sections at the same time (for example, 1/40 during bonus probability fluctuation, and 1/400 otherwise). ).
Further, the high probability game section shifts only after the bonus game where the bonus game is won by the stop display of a predetermined specific symbol (for example, the bonus symbol “7, 7, 7”), and other non-specific symbols (for example, The bonus game “BAR, BAR, BAR”) is stopped and displayed, and after the bonus game where the bonus is won, the low probability game section is entered.

In such a slot machine 10 equipped with a bonus probability variation function, since a bonus combination is also lottered even during bonus probability variation, a bonus combination is won in the low probability game section as shown in the time chart 4 of FIG. There are a winning pattern 1 for winning and a winning pattern 2 for winning a bonus combination in the high-probability game section.
Specifically, as shown in the time chart 4, when a bonus combination is won in the low-probability game section (A1), the winning probability of the re-playing combination from the next game after the winning game is low (1 / 7.3). ) To medium probability (1/3), and then the winning pattern 1 in which the medium probability (1/3) continues until the game (B1) that wins the bonus game, and when the bonus combination is won in the high probability game section ( A3) From the game after the winning game, the winning probability of the re-playing role fluctuates from a high probability (1 / 1.1) to a medium probability (1/3), and then to a game (B3) that wins a bonus game There are two patterns of winning pattern 2 in which the medium probability (1/3) continues.
Such a winning pattern is exactly the same as the winning patterns 1 and 2 in the above-mentioned slot machine 10 equipped with the ART function. Therefore, the control unit 33 estimates the winning timing of the bonus combination in the probability variation function-equipped slot machine 10 by the same estimation method as that for the ART function-equipped type slot machine 10 and counts each winning prize. Since the estimation of the patterns 1 and 2 can be performed, description of the estimation is omitted here.

On the other hand, in the case of the slot machine 10 of the bonus probability variation function-equipped type, there are a probability variation pattern that becomes a high probability game interval and a probability variation pattern that becomes a low probability game interval until the next bonus winning after the bonus game ends. Such a difference in probability state needs to be notified in a lighting manner such as a lamp as a high-probability game section in the calling lamp 20, for example, but a game signal that can specify a high-probability game section is directly from the slot machine 10. Is not output.
Therefore, the control unit 33 estimates the gaming state based on the re-game winning probability history PA after the bonus game ends as follows.

FIG. 15 is a diagram showing a time chart after the end of the bonus game in the time chart 4, a re-game winning history R, and a re-game winning probability history PA. FIG. 15A is an explanatory diagram when estimating a pattern without probability change. Yes, (b) is an explanatory diagram when estimating a pattern with probability variation.
The re-game winning probability history PA in each figure is obtained from the re-game winning history R for a total of 7 games (excluding games in bonus game) from the current game to the past 6 games after the bonus game ends. The winning combination probability is calculated every time one game progresses.

  Each time one game progresses from the eighth game after the bonus game ends, the control unit 33 determines that the winning probability of the re-gamer calculated in the current game is a predetermined threshold value (for example, the re-game winning probability history PA) (for example, 4/7) is exceeded or below, and when a predetermined number of games (for example, 3 games) continuously falls below a threshold value (for example, 4/7), the game section after the bonus game ends is determined. When a predetermined number of games (for example, 3 games) are continuously exceeded (exceeded by 4/7) for a predetermined number of games (for example, 3 games), the game section after the bonus game is estimated as a pattern with certain changes. To do.

The estimation result is transmitted to the calling lamp 30 and the hall computer 50. For example, when it is estimated that there is a probability variation pattern, a mark (star) is added to the item “ART” in FIG. 32. As a result, the calling lamp 20 lights up the lamp or the like in a manner corresponding to the probability state after the bonus game ends. That is, the call lamp 20 notifies the probability state after the end of the bonus game in the lighting mode indicating the probability variation state when the pattern with probability variation is received and in the lighting mode indicating the low probability state when the pattern without probability variation is received. Can do.
In addition, by estimating the gaming state after the bonus game is completed in this way, the gaming state when winning the next bonus combination can be estimated in advance, so that the above-described winning gaming state estimation performed at the start of the next bonus game is performed. The processing need not be executed, and the calculated estimated bonus winning probability can be directly stored according to the classification of “low probability estimated bonus winning probability” or “high probability estimated bonus winning probability” shown in FIG.
In the above estimation, the gaming state can be estimated based on the re-game winning probability history PB instead of the re-game winning probability history PA.

As described above, according to the gaming machine and gaming system of the present embodiment, the estimated bonus winning probability that is close to the bonus winning probability in the internal lottery is calculated even in the slot machine that does not output the internal winning signal. Can do.
When a player chooses a slot machine to play a game, the player often determines whether the set probability (six-stage set probability) is good or bad based on the bonus winning probability, but according to the bonus winning probability of the conventional method, Even if the setting probability of the slot machine is set to the setting probability of a high payout rate, the slot machine is overlooked by the player because it is presented with a lower probability than that. However, in the present invention, since a probability close to the bonus winning probability in the internal lottery is presented, there are advantages for both the game hall and the player.

The preferred embodiment of the game hall apparatus of the present invention has been described above, but the game hall apparatus according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.
For example, in the embodiment described above, the stand computer 30 is operated as a game hall device, but the calling lamp 20, the island computer 40, and the hall computer 50 can be operated as a game hall device.
Furthermore, in the present embodiment, the computer 30 functions as various means such as a bonus game start detection means, a re-game winning detection means, a re-game winning probability calculation means, a winning timing estimation means, an estimated bonus winning probability calculation means, These functions are shared by the call lamp 20, the island computer 40, and the hall computer 50, and the game field system operates as a single game field device by exchanging calculation results, detection results, and estimation results through mutual communication. It can also be made.
In addition, the predetermined number of games that can be traced back to the past from the current game when calculating the winning probability of the re-gamer in the re-game winning probability history PA can be determined according to the degree of change in the re-game player's winning probability. The form is not limited.
A slot machine equipped with an ART (assist replay time) function as a slot machine having a re-game high probability game section in which the re-game player win probability is set higher than the re-game player win probability in the internal winning game section.
