And the internal winning of the bonus combination can be analyzed with high accuracy. Therefore, it is possible to satisfy a player's request that the occurrence of an error has some influence on the internal winning of the bonus combination.
According to the invention described in claim 2, since the number of bonus winnings is counted separately in the normal state and the state after the error, the correlation between the occurrence of the error and the internal winning of the bonus combination is analyzed with higher accuracy. can do.

The front view of the slot machine with which the game information display apparatus by one Embodiment of this invention is attached The figure which shows the number of winning random numbers of slot machine and the reciprocal number of internal winning probability Functional block diagram showing the electrical configuration of the slot machine The figure which shows an example of the normal data screen of a game information display apparatus The figure which shows an example of the data screen after an error of a game information display device The figure which shows an example of the detailed data screen after an error of a game information display device

Hereinafter, a game information display device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 schematically shows a front appearance of the slot machine 1. A display window 2 is provided in front of the slot machine 1, and the player can visually recognize the symbol of the reel 3 (corresponding to symbol variation display means) provided inside through the display window 2. Each symbol is drawn on the circumferential surfaces of the left reel 3a, middle reel 3b, and right reel 3c. These symbols are displayed corresponding to the upper, middle, and lower stages of the display window 2 when the reels 3a to 3c are stopped. That is, the slot machine 1 is formed with a symbol display area for a total of nine symbols, three symbols for each of the reels 3a to 3c.

  FIG. 2 shows the types of roles set in the slot machine 1 and the number of winning random numbers and the reciprocal of the internal winning probability when the setting values of the slot machine 1 are setting 1 and setting 6. The slot machine 1 has a plurality of types of small combinations and bonus combinations, of which two types of bonus combinations are the BB combination and the RB combination, and the small combination is a single combination, two combinations, eight combinations and 15 Four types of sheets are set. As will be described later, the slot machine 1 can set a set value from 1 to 6, generates a total of 65536 random numbers in the range of 0 to 65535, and receives a winning random number for each combination within the range. Allocated. In this embodiment, for example, in the case of setting 1, 110 winning random numbers are allocated to the BB combination, and the internal winning probability is 110/65536 = 1 / 595.8. That is, the BB combination is theoretically won internally by a rate of once per 595.8 games (hereinafter referred to as a single winning). Further, 60 winning random numbers are assigned to the RB combination, and the internal winning probability is 60/65536 = 1 / 1092.3.

  Here, the BB + 2 sheet combination, the BB + 15 sheet combination, the RB + 2 sheet combination, and the RB + 15 sheet combination will be described. The BB + 2 piece combination means that the BB combination and the two piece combination are simultaneously determined as internal winning combinations (hereinafter referred to as simultaneous winning combinations). This is a state in which the flag is established at the same time. Similarly, BB + 15 combination indicates that BB combination and 15 combination are elected simultaneously, RB + 2 combination is RB combination and 2 combination, RB + 15 combination is RB combination and 15 combination is selected simultaneously. It shows that That is, the slot machine 1 is provided with a state where a bonus combination is won independently and a state where a bonus combination is won simultaneously. Of these, 50 winning random numbers are assigned to the BB + 2 winning combination, 60 to the BB + 15 winning combination, 30 to the RB + 2 winning combination, and 30 to the RB + 15 winning combination. Also, among the small roles, 500 winning random numbers are assigned, 1500 for the 2 winning characters, 9000 for the 8 winning characters, and 1000 winning random numbers for the 15 winning characters. Is assigned 8980 winning random numbers.

On the other hand, in the case of setting 6, for example, 140 winning random numbers are allocated to the BB combination, and the internal winning probability is 140/65536 = 1 / 468.1. In addition, 110 winning random numbers are assigned to the RB combination, and the internal winning probability is 110/65536 = 1 / 595.8. In addition, 50 winning random numbers are assigned to the BB + 2 winning combination, 50 to the BB + 15 winning combination, 40 to the RB + 2 winning combination, and 50 to the RB + 15 winning combination. The number of winning random numbers for each small role is allocated as in the case of setting 1.
With this setting, in the case of setting 1, the BB total that is the number of winning random numbers that the BB combination wins internally is 220, and the RB total that is the number of winning random numbers that the RB combination wins internally is 120, In the case of setting 6, the total BB is 290 and the total RB is 220. As described above, the slot machine 1 is set such that the larger the set value, the larger the number of winning random numbers for the bonus combination and the number of winning random numbers for the small combination as the number of simultaneous winnings increases. That is, the slot machine 1 is set so that the higher the set value, the higher the theoretical internal winning probability of bonus combination and small combination. The number of winning random numbers in the bonus state is the same for all set values. Further, the settings 2 to 5 and the bonus state are omitted.

On the left side of the display window 2, as shown in FIG. 1, there is provided an effective line display unit 4 that shows the activated winning line. The slot machine 1 is provided with a total of five effective lines (three in the horizontal direction and two in the diagonal direction corresponding to the upper, middle, and lower stages of the display window 2). When the symbols corresponding to the internal winning combination are aligned on any of these active lines, that is, the combination of symbols stopped on the active line matches the combination of symbols corresponding to the internal winning combination. Wins occur when you win.
Above the display window 2, a liquid crystal display unit 5 as a game information display device for displaying various information and a speaker 6 are provided. Below the display window 2 are provided a credit button 7 for inserting a credit medal, a settlement button 8 for adjusting a credit medal, and a medal insertion slot 9 for inserting a medal. A start lever 10 corresponding to the means, a left stop button 11a corresponding to the stop operation means, a middle stop button 11b, a right stop button 11c, and a data display button 12 for switching the type of data displayed on the liquid crystal display unit 5 are provided. It has been. On the right side of the display window 2, a payout number display unit 13 for displaying the number of paid-out medals, a credit number display unit 14 for displaying the number of medal credits, and a bonus notification lamp for notifying the player of the internal winning of the bonus combination. 15 is provided. In addition, a tray 16 is provided at the lowermost front part of the slot machine 1, and a decorative lamp part 17 is provided at the uppermost front part.

Here, the gaming state of the slot machine 1 will be described. The slot machine 1 is provided with two game states, a normal state and a bonus state, and these game states are switched in accordance with the establishment of a predetermined condition. In the normal state, the number of medals required for one game (the number of BETs) is three (3 BETs), and the corresponding number of medals is awarded to the player according to the winning combination by the player. When the bonus combination (BB combination or RB combination) wins in the normal state, the slot machine 1 shifts to a bonus state (BB state or RB state) corresponding to the winning bonus combination (generates a bonus state). .
This bonus state is a state in which the internal winning probability of each small role is greatly increased. In the bonus state, the number of medals required for one game (the number of BETs) is reduced to two (2 BETs). For this reason, the bonus state is a gaming state that is advantageous to the player because a large number of medals can be obtained at once and the number of BETs is reduced to two. In other words, it can be said that the normal state is a gaming state that is disadvantageous for the player as compared to the bonus state. This bonus state continues until a predetermined bonus end condition is satisfied. In the present embodiment, a predetermined number of medals are paid out as a bonus end condition, and the bonus state continues until 360 medals are paid out in the BB state and 120 medals are paid out in the RB state. The slot machine 1 shifts to the normal state when the bonus state ends.

Next, the electrical configuration of the slot machine 1 will be described.
FIG. 3 shows the electrical configuration of the slot machine 1 as functional blocks. Control unit 18 (internal lottery means, display control means, winning determination means, game medium giving means, bonus state generating means, post-error game number counting means, normal game number counting means, normal bonus combination number counting means, post-error bonus combination (Corresponding to the number counting means) is composed of a microcomputer equipped with a CPU, ROM, RAM, I / O, etc., and includes a credit button 7, a settlement button 8, a start lever 10, a left stop button 11a, and a middle stop button. Various signals are input from 11b, the right stop button 11c, the inserted medal detection unit 19, the set value operation unit 20, and the like.

  When the inserted medal detection signal is input from the inserted medal detection unit 19 that determines the authenticity and quantity of the inserted medals, the control unit 18 counts the number of medals inserted based on the number of the input signals. To do. The slot machine 1 can insert medals according to two insertion modes, that is, a maintenance insertion from the medal insertion slot 9 and a credit insertion by pressing the credit button 7. When the number of inserted medals exceeds the prescribed number required for one game (three in the normal state), the control unit 18 sets the number of medals exceeding the predetermined number in a RAM or the like as a credit number. While storing up to the upper limit (for example, 50), the number of credits is displayed on the credit number display unit 14. In addition, the control unit 18 stores the medals paid out with the winning of the small role as the number of credits. At this time, when the number of credits is less than the upper limit, the number of payouts is added to the number of credits, and when the credit number reaches the upper limit, medals are paid out to the tray 16.

Various setting signals such as a winning probability are input to the control unit 18 from the set value operation unit 20. As described above, the slot machine 1 is provided with setting values for setting the internal winning probabilities of the respective roles in six stages of settings 1 to 6, and the setting value operation unit 20 is selected by the game hall staff. Enables one arbitrarily selected set value. Thereby, the payout rate is set as a theoretical value (see FIG. 2). In the setting value operation unit 20, after the setting change key 21 is inserted to make the setting changeable, the setting value is changed by, for example, switching a DIP switch (not shown).
The control unit 18 also includes various display units such as the liquid crystal display unit 5, the payout number display unit 13 and the credit number display unit 14, a bonus notification lamp 15, a decoration lamp unit 17, and reel motors corresponding to the reels 3a to 3c. A reel drive unit 22 that drives the reference position detection unit 23 that detects a reference position of each of the reels 3a to 3c based on a detection signal from a sensor that detects passage of a reference position piece provided in each of the reels 3a to 3c, The sound output unit 24 that drives the speaker 6 is connected. In addition, it is connected to the medal payout unit 25 for paying out medals, and when the checkout button 8 is operated, the medal payout unit 25 is controlled so as to pay out medals corresponding to the stored number of credits. The display on the credit amount display unit 14 is set to zero.

  The controller 18 has a random number generator and a random number extractor (not shown). When the start lever 10 is operated with a medal inserted (when a game start operation is performed), the control unit 18 starts (rotates) each reel 3a to 3c. Subsequently, one random number is extracted from the random numbers generated by the random number generation unit by the random number extraction unit, and an internal lottery for determining the internal winning combination is executed. A flag corresponding to the combination is established. At this time, when determining that the bonus combination is an internal winning combination (in the case of internal winning), the control unit 18 lights the bonus notification lamp 15 to notify the player that the bonus combination has been won internally. .

  Subsequently, when each of the stop buttons 11a to 11c is operated in a state where the reels 3a to 3c are started, the control unit 18 stops the rotation of the corresponding reels 3a to 3c. At this time, based on a stop table (not shown) for determining the stop position of each reel 3a to 3c according to the flag of the internal winning combination, stop control including so-called pull-in control (slip control) (respective reels 3a to 3c (Control to stop display with winning symbol or lost symbol according to the type of the internal winning combination flag). The stop table is set for each type of internal winning combination flag. The pull-in control is a control capable of pulling and stopping a symbol within a predetermined pull-in range (up to four symbols) on the effective line from the time when the operation of each stop button 11a to 11c is detected. In this case, when the symbol corresponding to the internal winning combination flag does not exist within the above-described drawing range, the symbol cannot be drawn on the active line and stopped, so that no winning occurs, so-called missing.

  Moreover, the control part 18 is connected to the sensor which is provided in the specific site | part which is not shown in figure, and detects generation | occurrence | production of an error based on the detection state of each sensor. Also, if any error has occurred, for example, an indication that an error has occurred is displayed on the liquid crystal display unit 5, or that an error has occurred from an output unit (not shown) to an external call lamp or management device. To notify that an error has occurred. The specific part is, for example, a hopper (not shown) provided in the slot machine 1 for storing medals, a medal slot 9 or the like. If the control unit 18 detects a shortage of medals in the hopper based on a detection state of a payout medal sensor provided at a medal payout exit (not shown) of the hopper, an error of shortage of medals (an error that medals are not paid out when winning) Informs that this has occurred. Other types of errors that occur in the slot machine 1 include a medal full error that fills up medals in the hopper, and an inserted medal clogged error that causes the medal slot 9 to be filled with medals.

Next, the operation of the liquid crystal display unit 5 as a game information display device will be described.
Normally, the liquid crystal display unit 5 displays a normal data screen as shown in FIG. The normal data screen includes a current game number display part M1, a cumulative game number display part M2, a BB number [probability] display part M3, an RB number [probability] display part M4, a continuous number of times display part M5, and a bonus game A number graph M6 is provided, which displays the following game data.
・ Number of games now = Number of games executed from the end of the previous bonus state to the present time.
-Cumulative number of games = number of games in normal state (non-bonus state).
Number of BB [probability] = Number of winning BB and winning probability (number of winning / total number of games). Usually corresponds to the number of bonus combinations.
RB count [probability] = RB winning count and winning probability (winning count / total number of games). Usually corresponds to the number of bonus combinations.
-Number of consecutive chunks = number of bonus states determined to be consecutive. In the present embodiment, it is determined that a continuous change has occurred when the bonus combination is won again within a predetermined number of games (for example, 100 games) after the previous bonus state ends.

Each of these data is updated with the progress of the game by the player, for example, when the BB combination or the RB combination wins or when it is determined that a continuous change has occurred. At this time, the bonus game number graph M6 is also updated. The inter-bonus game number graph M6 displays the number of past 10 bonus games (the number of games executed during the bonus state) in a bar graph format, and one scale corresponds to 100 games. In addition, the type of bonus combination (BB or RB) generated corresponding to the bar graph is shown below each bar graph. In the example of FIG. 4, since the bonus combination of the previous time (corresponding to “1”) is the BB combination and the graph is one scale, the number of games between bonuses is less than 100 games.
The liquid crystal display unit 5 displays game data as shown in FIG. 4 and notifies that an error has occurred due to a message (not shown), but these are performed individually. In that case, as described above, the player who thinks that the occurrence of the error will have some influence on the internal winning of the bonus combination needs to check the game number display section M1 etc. himself or herself each time. It is difficult to grasp the relationship between the occurrence and the internal winning of the bonus combination. In addition, it is virtually impossible to grasp all the error situations that have occurred in other gaming machines that the player does not play.

Therefore, the liquid crystal display unit 5 displays game data that can estimate the correlation between the occurrence of an error and the internal winning of the bonus combination.
When the generated error is resolved, that is, when error cancellation is detected, the control unit 18 of the slot machine 1 changes the display on the liquid crystal display unit 5 from the normal data screen shown in FIG. 4 to the post-error data screen shown in FIG. Switch to. For example, when a medal clogging error occurs, the employee opens the front door of the slot machine 1 to remove the clogged medal, thereby eliminating the medal clogging error. Then, when the control unit 18 detects the cancellation of the medal jam error, the control unit 18 switches the display on the liquid crystal display unit 5 from the normal data screen (FIG. 4) to the post-error data screen (FIG. 5). The example of the post-error data screen shown in FIG. 5 shows an example of the screen display at the time when one game is executed after, for example, a medal clogging error occurs and the error is canceled when the number of current games is 125. Yes.

In the post-error data screen, in addition to the above-mentioned current game number display unit M1, cumulative game number display unit M2, BB count [probability] display unit M3 and RB count [probability] display unit M4, a post-error game number display unit M7 and a post-error accumulated game number display section M8 are provided, and the following game data is displayed.
-Number of games after error: Number of games from the time when error cancellation (error has been resolved) is detected (number of games executed by the player in the state after error).
・ Total number of games after error: Total number of games after error on the current day.
In this case, the screen display example of FIG. 5 indicates that the number of post-error games is 1, and the cumulative number of post-error games on the current day is 356. That is, FIG. 5 shows the game data in a state (number of now games = 126) in which one error has occurred after the error is solved in the state shown in FIG. 4 (current number of games = 125). ing. The data screen after the error is switched to the normal data screen when the next bonus state occurs and is finished.

Now, the player can view more detailed data by operating the data display button 12 during the period in which the post-error data screen shown in FIG. 5 is displayed.
When the data display button 12 is operated by the player, the control unit 18 switches the screen of the liquid crystal display unit 5 to a post-error detailed data screen shown in FIG. This error detail data screen is provided with an error occurrence number display part M9, an after-error BB number display part M10, and an after-error RB number display part M11, and displays the following data. Note that the BB number [probability] display unit M3 and the RB number [probability] display unit M4 indicate the number of BB winnings and the number of RB winnings in the base game and the post-error state, respectively.
-Error occurrence count: The cumulative number of times an error has occurred. The type of error is unquestioned.
-BB count after error: The number of times the BB role won in the post-error state. Usually corresponds to the number of bonus combinations.
-Number of RBs after error: Number of times the RB role won in the state after error. Usually corresponds to the number of bonus combinations.
In the case of FIG. 6, the bonus state occurs four times in the post-error state, three of which are in the BB state and one in the RB state.

  In this way, the number of post-error games executed in the post-error state from when the error is resolved until the bonus combination is won internally as shown in FIG. 5 is displayed on the liquid crystal display unit 5. Further, as shown in FIG. 6, the number of normal games executed in a normal state where no bonus state has occurred, the number of BBs and RBs that are the number of normal bonus combinations, and the post-error BB that is the number of bonus combinations after an error The number of times and the number of RBs after an error are displayed. Thus, for example, in the case of FIG. 6, the player can make a guess that the BB combination may be more likely to win an internal winning when an error occurs.

According to the game information display device of the present embodiment described above, the following effects are obtained.
The number of games executed in the post-error state from when the error is resolved until the bonus combination is won internally is displayed as the number of post-error games. Can be analyzed with high accuracy. Therefore, it is possible to satisfy a player's request that the occurrence of an error has some influence on the internal winning of the bonus combination.
In addition, the liquid crystal display unit 5 displays the total number of bonus winnings in a distinction between the normal state and the post-error state, so that the correlation between the occurrence of the error and the internal winning of the bonus combination is more accurate. Can be analyzed.

(Other embodiments)
The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
Although the game information display device is provided integrally with the slot machine, it may be provided separately from the slot machine.
The present invention can also be applied to a slot machine that uses game balls as game media.
The post-error state is from when the error is resolved until the bonus combination is won internally, but the post-error state may be from when the error is resolved until the bonus combination is won.
Although the state where the bonus state has not occurred (non-bonus state) is the normal state, the state after the error state is excluded from the state where the bonus state has not occurred may be the normal state.
