A symbol determining unit (Sa507) for determining, and a privilege granting unit (Sa50) for granting a privilege according to the symbol combination determined by the symbol determining unit. , Sa509), and the symbol determination means is information for identifying a symbol combination stopped on the winning line, and the symbol identification information defined in advance to identify each symbol by mutually exclusive logical information Stop symbol information specified as a combination of the above (information on the combination of symbol identification information on each reel R as a symbol combination on the winning line L1), and information for identifying the symbol combination associated with the privilege, A logical operation (logic of the combination of symbol identification information corresponding to each reel R for identifying a symbol combination constituting a predetermined combination) defined in advance as the symbol identification information combination Product), the symbol combination on the winning line is determined.

  The “mutually exclusive logical information” constituting the symbol identification information that is information for identifying the symbol is, for example, when a value (symbol identification information) corresponding to each symbol is expressed in a binary number format, This means that the digit that is 1 is different for every symbol. Alternatively, any other format may be adopted as long as it is a format suitable for determining the match or mismatch of values using a logical operation such as logical sum (OR) or logical product (AND).

  By configuring the gaming machine in this way, both symbols are matched by a logical operation between the identification information of the symbols stopped on the winning line and the identification information of the symbols to be compared as symbols constituting the predetermined role. Alternatively, since it is possible to determine the mismatch, it is possible to effectively reduce the processing load on the gaming machine.

  Further, in the gaming machine of the present invention, the determination symbol information includes a plurality of individual determination symbol information (one symbol identification information constituting the determination symbol information) for identifying each symbol, and the plurality of individual determinations At least one of the symbol information may be configured as a logical sum of the plurality of symbol identification information.

  By configuring the gaming machine in this way, both symbols are matched or mismatched by the same arithmetic processing as the logical operation described above while including information on a plurality of symbol types in one value (individually determined symbol information). Therefore, it is possible to effectively reduce the capacity of data stored in the gaming machine.

They may be stored in the storage device in order.

  The fact that the determination symbol information is stored in the storage device in the order of the symbol combination that is likely to stop on the winning line means that the earlier the order referred to in the symbol combination determining process, the faster it can stop on the winning line. This means that the determination symbol information is stored in the storage device in an order that results in a symbol combination having high characteristics.

  By configuring the gaming machine in this way, it is possible to increase the data retrieval efficiency in the symbol combination determination process, so that the processing load on the gaming machine can be effectively reduced.

  In the gaming machine of the present invention, the determination symbol information includes privilege identification information (privilege information) that is information for identifying the type of the privilege, and the privilege granting unit is specified by the symbol determination unit. A privilege to be granted may be identified based on the privilege identification information included in the symbol determination information corresponding to a combination.

  By configuring the gaming machine in this way, a single value (determination symbol information) can include a plurality of pieces of information including information identifying a symbol and information identifying a privilege type. It is possible to effectively reduce the volume of data stored in the.

  According to the present invention, the processing load for determining whether or not a specific symbol combination is stopped and displayed on the winning line is reduced, and the capacity of determination data prepared in advance for the processing is reduced. It is possible to provide a gaming machine that can be used.

<4. Basic game processing>
A flow of processing related to one game in the slot machine 1 will be described with reference to FIG.

<4-1. Flow of processing>
(1) Medals Accepting Process When a medal is inserted into the medal insertion slot 10, the slot machine 1 accepts the inserted medal and takes it into the slot machine 1 or accepts the inserted medal in the medal tray 40. (Step Sa501).

  Specifically, when the bet number is 3 and the credit number is less than 50, when a medal is inserted into the medal slot 10, the CPU 101 takes the inserted medal into the slot machine 1 and inserts it. Add credits by the number of medals. When the bet number is 3 and the credit number is 50, when a medal is inserted into the medal insertion slot 10, the CPU 101 drives a solenoid provided in the medal detection device to insert the inserted medal into the medal tray 40. Return to

(2) Bet processing The slot machine 1 sets the number of bets necessary to start the game in accordance with the insertion of medals into the medal insertion slot 10, the operation of the bet button 11, or the winning of the re-gamer (step Sa502) ).

  Specifically, when a bet is less than 3, when a medal is inserted into the medal slot 10, the CPU 101 adds the bet number by the number of inserted medals. When the bet button 11 is operated when the bet number is less than 3, the CPU 101 subtracts the credit number and adds the bet number. Although details will be described later, when the re-game player wins, the CPU 101 executes an automatic bet process for betting again the bet number bet on the game without subtracting the credit amount.

(3) Lever Acceptance Processing The slot machine 1 starts a game when the start lever 12 is operated with three medals being bet (step Sa503). Specifically, when the start lever 12 is operated with the bet number set to 3, the CPU 101 executes a game process after an internal lottery process described later. On the other hand, when the start lever 12 is operated with the bet number set to less than 3, the CPU 101 does not execute the game process after the internal lottery process.

(4) Internal lottery process As the game starts, the slot machine 1 determines information for deriving a game result by lottery (step Sa504). When the start lever 12 is operated with the bet number set to 3, the CPU 101 executes an internal lottery process. Details of the internal lottery process will be described later.

(5) Reel Rotation Process After executing the internal lottery process, the slot machine 1 rotates each of the reels R1 to R3 in order to display the symbols arranged on the reel R in a variable manner (step Sa505). Specifically, the CPU 101 rotates each of the reels R1 to R3 by continuously supplying pulses to each of the stepping motors 54a to 54c after executing the internal lottery process.

(6) Reel Stop Processing The slot machine 1 stops the rotation operation of the reel R when the stop button 13 is operated during the rotation of the reel R (step Sa506). When the stop button 13 corresponding to the rotating reel R is operated, the CPU 101 responds by supplying a predetermined pulse to the stepping motor 54 to which the reel R corresponding to the operated stop button 13 is fixed. The rotation operation of the reel R is stopped. Details of the reel stop process will be described later.

(7) Symbol Determination Process The slot machine 1 determines the symbol combination that is stopped and displayed on the winning line L1 after all of the reels R1 to R3 are stopped (step Sa507). After all of the reels R1 to R3 are stopped, the CPU 101 determines whether or not the symbol combination stopped and displayed on the winning line L1 is a predetermined symbol combination determined in advance. For example, it is determined whether or not the symbol combination stopped and displayed on the winning line L1 is a symbol combination corresponding to the winning combination. Details of the symbol determination process will be described later.

(8) Medal payout process When the slot machine 1 determines that the symbol combination corresponding to the small combination is stopped and displayed on the winning line L1, the medal payout process is executed (step Sa508). Details of the medal payout process will be described later.

(9) State Transition Process The slot machine 1 shifts the game state according to the game result (step Sa509). For example, when it is determined that the symbol combination corresponding to the bonus combination is stopped and displayed on the winning line L1, the CPU 101 shifts the gaming state to the gaming state corresponding to the bonus combination. After executing the state transition process, the slot machine 1 ends the process related to one game.

Details of each process relating to the above-described one-time game will be described.

(1) Details of Internal Lottery Processing Details of the internal lottery processing in the slot machine 1 will be described. The internal lottery process is a process for determining, by lottery, a winning combination of one or a plurality of combinations or a loss that does not win any combination from a plurality of predetermined combinations, and is executed using a lottery table.

  FIG. 6 is an explanatory diagram for explaining a lottery table used in the internal lottery process in the slot machine 1. The lottery table includes a correspondence relationship between one or more winning combinations and one lottery value. The lottery value indicates the lottery probability of the combination corresponding to the lottery value.

  In the internal lottery process, the CPU 101 acquires one random number value from a range of 0 to 65535 from a random number generator (not shown). Next, a corresponding lottery value is specified while sequentially comparing the acquired random value with a plurality of lottery values defined in the lottery table. Specifically, the CPU 101 compares the random value acquired from the random number generator with the first lottery value in the internal lottery table. As a result of the comparison, if the random value is less than the lottery value, the winning of the combination associated with the first lottery value is determined. If the random value is greater than or equal to the lottery value, the random value is compared with a value obtained by adding the second lottery value to the first lottery value. As a result of the comparison, if the random value is less than the total value of the first and second lottery values, the winning of the combination associated with the second lottery value is determined.

  In this way, the combination associated with the Nth lottery value when the random number value is repeated until the random value becomes less than the total value of the first to Nth lottery values is determined as the winning combination. For example, when the random number value acquired from the random number generator is 342, the CPU 101 adds 100, which is the second lottery value, to the value because the random number value is 50 or more, which is the first lottery value. Since the random value 342 is 150 or more which is the total value of the first and second lottery values, 300, which is the third lottery value, is added thereto. Since the random value 342 is less than 450 which is the total value of the first to third lottery values, the winning of the “RB1” combination associated with the third lottery value is determined.

(2) Details of Reel Stop Processing Details of the reel stop processing in the slot machine 1 will be described. When receiving the operation of the stop button 13 corresponding to the rotating reel R, the CPU 101 stops the corresponding reel R. This is repeated until all of the reels R1 to R3 are stopped. At this time, the CPU 101 stops the corresponding reel R within the range of the reel rotation amount for a maximum of four symbols from the time when the stop button 13 is operated. Further, when winning of any combination is determined by the internal lottery process, the CPU 101 draws the symbol combination related to the winning combination onto the winning line L1 within the range of the reel rotation amount for a maximum of 4 symbols. Thus, the reel R is stopped.

  For example, in the situation where the reels R1 to R3 are rotating and the winning of the “watermelon” role (design combination “watermelon-watermelon-watermelon”) is determined by the internal lottery process, the CPU 101, for example, in the left reel R1 When the left stop button 13a is operated at the timing when the “Bell B” symbol of symbol number PN = 15 is positioned on the winning line L1, the left reel R1 is continuously rotated by two symbols, and symbol number PN = The left reel R1 is stopped so that 17 “watermelon” symbols are stopped and displayed on the winning line L1.

  Next, for example, when the middle stop button 13b is operated at the timing when the “cherry” symbol of symbol number PN = 21 on the middle reel R2 is positioned on the winning line L1, the CPU 101 rotates the middle reel R2 by three symbols. The operation is continued, and the middle reel R2 is stopped so that the “watermelon” symbol of symbol number PN = 3 is stopped and displayed on the winning line L1.

  Next, for example, when the right stop button 13c is operated at the timing when the “blue 7” symbol of symbol number PN = 8 on the right reel R3 is positioned on the winning line L1, the CPU 101 moves the right reel R3 by one symbol. The rotation operation is continued, and the right reel R3 is stopped so that the “Plum A” symbol of symbol number PN = 9 is stopped and displayed on the winning line L1. As a result of all the reels R1 to R3 being stopped, the “watermelon” symbol (left reel R1), the “watermelon” symbol (middle reel R2), and the “plum A” symbol (right reel R3) are stopped on the winning line L1. Is displayed.

  The reason why the “watermelon” symbol is not displayed on the winning line L1 in the right reel R3 even though the “watermelon” role is determined by the internal lottery process is that the right stop button 13c is operated in the right reel R3. This is because the “watermelon” symbol does not exist between the symbol number PN = 8, which is the assigned timing, and the symbol number PN = 12, which is four symbols ahead. When the stop button 13 is operated at such timing, a predetermined symbol within a range of a maximum of four symbols from a symbol positioned on the winning line L1 at the timing when the stop button 13 is operated is won. Stop display on the line L1.

  The reel stop process in the slot machine 1 is realized using a stop table. In the stop table, at the timing when the stop button 13 is operated, the symbol number PN indicating the symbol positioned on the winning line L1, the number of sliding symbols indicating the rotation amount of the rotating operation to be continued until the reel R is stopped, and Are defined for each reel.

  FIG. 7 is an explanatory diagram for explaining a stop table used in the reel stop process in the slot machine 1. FIG. 7 shows an example of the stop table, which is used when the stop button 13 is pushed forward when the winning combination of “watermelon” (design combination “watermelon-watermelon-watermelon”) is determined by the internal lottery process. Shows the contents of the stop table.

  A reel stop process executed with reference to the stop table for realizing stop control in the case where the stop button 13 is pushed forward when the “watermelon” combination is won will be described below. When the left stop button 13a is operated at a timing when the “Bell B” symbol of symbol number PN = 15 is positioned on the winning line L1 while the left reel R1 is rotating, the CPU 101 refers to the stop table and refers to the left reel. The number of sliding symbols 2 corresponding to the symbol number PN = 15 of R1 is acquired, and the left reel R1 is stopped after continuing the rotation operation for two symbols corresponding to the acquired number of sliding symbols. As a result, the left reel R1 is stopped at the timing when the “watermelon” symbol of symbol number PN = 17 is positioned on the winning line L1.

  Further, when the middle stop button 13b is operated at a timing when the “cherry” symbol of symbol number PN = 21 is positioned on the pay line L1 while the middle reel R2 is rotating, the CPU 101 refers to the stop table. The number of sliding symbols 3 corresponding to the symbol number PN = 21 of the reel R2 is acquired, and after the rotation operation is continued for the 3 symbols corresponding to the acquired number of sliding symbols, the middle reel R2 is stopped. As a result, the middle reel R2 is stopped at the timing when the “watermelon” symbol of symbol number PN = 3 is positioned on the pay line L1.

  When the right stop button 13c is operated at the timing when the “blue 7” symbol of symbol number PN = 8 is positioned on the pay line L1 while the right reel R3 is rotating, the CPU 101 refers to the stop table. The number of sliding symbols corresponding to the symbol number PN = 8 of the right reel R3 is acquired, and the rotation operation is continued by one symbol corresponding to the acquired number of sliding symbols, and then the right reel R3 is stopped. As a result, the right reel R3 is stopped at the timing when the “Plum A” symbol of symbol number PN = 9 is positioned on the winning line L1.

  Even when each stop button 13 is operated at a timing other than the above, the stop table is similarly referred to, and the timing at which the stop button 13 is operated (positioned on the pay line L1 when the stop button 13 is operated). The number of sliding frames corresponding to the symbol number PN) is acquired, and the rotation operation of the reel R is continued for the acquired number of sliding frames, and the reel R is stopped. That is, in the reel stop process using the stop table, the amount of the rotation operation to be continued until the reel R is stopped is determined according to the number of sliding pieces of the reel R according to the operation timing of the stop button 13 predetermined in the stop table. It is determined.

  As described above, in the reel stop process of the slot machine 1, the symbol combination related to the winning combination determined by the internal lottery process is placed on the winning line L1 within the range of up to four symbols from the timing when the stop button 13 is operated. The reel stop process is executed so that the combination of symbols related to the winning combination that is not displayed and stopped is not displayed on the winning line L1. Further, in the reel stop process of the slot machine 1, the number of bets, the winning state determined in the internal lottery process, the stop position of the stopped reel, the pressing order of the stop button 13, and the operation timing of the stop button 13 are the same. If there is, the reel R is controlled to always stop at the same stop position. In order to realize this, the CPU 101 executes reel stop processing using a stop table configured by appropriately combining element data of a predetermined stop table according to the various conditions and states described above.

(3) Details of Symbol Determination Processing Details of symbol determination processing in the slot machine 1 will be described. When all of the reels R1 to R3 are stopped, the CPU 101 executes a symbol determination process for determining a symbol combination that is stopped and displayed on the winning line L1.

  FIG. 8 is an explanatory diagram for explaining a symbol identification table used in the symbol determination process in the slot machine 1. The symbol identification table includes a correspondence relationship with symbol identification information as numerical information for identifying the symbol type of the reel R. The symbol identification information is defined in advance as numerical information such that the number of digits of 1 when expressed in binary numbers is different in all symbols and becomes mutually exclusive logical information.

As described above, the slot machine 1 manages the amount of pulses supplied to the stepping motor 54 as the number of steps in the control of the rotation and stop of the reel R, and the design of each reel R located on the winning line L1 is Always grasped by the CPU 101. For example, the symbol combination on the winning line L1 is managed as a combination of the symbol identification information described above.
The symbol determination process in the slot machine 1 is a process for determining a symbol combination stopped and displayed on the winning line L1, and is executed using a symbol determination table.

  FIG. 9 is an explanatory diagram for describing a symbol determination table used in symbol determination processing in the slot machine 1. The symbol determination table is provided when the symbol combination corresponding to each reel R for identifying symbol combinations constituting a predetermined combination and the symbol combination is stopped and displayed on the winning line L1. The correspondence relationship with privilege information indicating the type of privilege to be included is included.

  For example, when the symbol combination “red 7-red 7-red 7” is stopped and displayed on the winning line L1, the process of shifting the gaming state to the bonus game state (BB1 state) as a privilege won by the “BB1” role. Indicates that it will be executed. Further, for example, when the symbol combination “Bell A-Bell A-Bell A” or “Bell B-Bell B-Bell B” is stopped and displayed on the winning line L1, 15 It shows that a process of paying out medals is executed.

  As described above, in a state where all the reels R are stopped, the CPU 101 grasps the combination information of the symbol identification information on each reel R as the stopped symbol information as the symbol combination on the winning line L1.

The CPU 101 refers to the symbol determination table and searches for the same symbol combination as the symbol combination indicated by the stop symbol information. For example, the symbol combination “black BAR-black BAR-black BAR” stops on the winning line L1,
When the stop symbol information is known to the CPU 101 as “00000100 (left) -00000100 (middle) -00000100 (right)”, the same symbol combination as the symbol combination indicated by the stop symbol information is referred to the symbol determination table. Search for.

  First, the CPU 101 refers to the first record in the symbol determination table. The CPU 101 compares the symbol identification information (00000100) corresponding to the left reel in the stop symbol information with the symbol identification information (00000001) corresponding to the left reel in the first record of the symbol determination table. Specifically, if the logical product of the two values is 0, it is determined that the symbols do not match, and if it is not 0, the symbols are determined to be the same. For the first record, the logical product of the symbol identification information corresponding to the left reel is 0, and it is determined that the symbols do not match. Therefore, at this time, the CPU 101 determines that the symbol combination does not match in the first record. .

  Next, the CPU 101 executes the same calculation process for the second record. The CPU 101 calculates a logical product of the symbol identification information (00000100) corresponding to the left reel in the stop symbol information and the symbol identification information (00000010) corresponding to the left reel in the second record of the symbol determination table. Since the logical product of both values is 0, the CPU 101 determines that the symbol combination does not match in the second record at this time.

  Next, the CPU 101 executes similar arithmetic processing for the third record. The CPU 101 calculates a logical product of the symbol identification information (00000100) corresponding to the left reel in the stop symbol information and the symbol identification information (00000100) corresponding to the left reel in the third record of the symbol determination table.

  Since the logical product of both values is other than 0, the CPU 101 next corresponds to the symbol identification information (00000100) corresponding to the middle reel in the stop symbol information and the middle reel in the third record of the symbol determination table. The logical product with the symbol identification information (00000100) is calculated.

  Since the logical product of both values is other than 0, the CPU 101 next corresponds to the symbol identification information (00000100) corresponding to the right reel in the stop symbol information and the right reel in the third record of the symbol determination table. The logical product with the symbol identification information (00000100) is calculated.

  The logical product of the two values is other than 0, which means that the symbol identification information in all symbols of the reels R in the stop symbol information and the third record of the symbol determination table match. It is determined that the symbol combination indicated by the information matches the symbol combination indicated by the third record. That is, it is determined that the symbol combination “black BAR−black BAR−black BAR” is stopped and displayed on the winning line L1.

Next, the CPU 101 specifies that the privilege information in the third record is “RB1”.
Thereby, in response to the symbol combination “black BAR-black BAR-black BAR” being stopped and displayed on the winning line L1, the game state is shifted to the bonus game state (RB1 state) in the state transition process described later. Processing can be executed.

  In the above-described example, the case where the same symbol combination as the symbol combination indicated by the stop symbol information is searched in the symbol determination table has been described. However, the symbol combination indicated by the stop symbol information is the symbol combination of any record in the symbol determination table. If they do not match, the CPU 101 determines that no winning combination has been won.

(4) Details of Medal Payout Processing Details of the medal payout processing in the slot machine 1 will be described. When the CPU 101 determines that the symbol combination corresponding to the small combination is stopped and displayed on the winning line L1 by the symbol determination process, the CPU 101 executes a medal payout process according to the small combination.

  The small role is a role associated with a payout of a medal as a prize for winning a prize. In the slot machine 1, a “watermelon” role (design combination “watermelon-watermelon-watermelon”, etc.), a “cherry” role ( Symbol combination “Cherry-Cherry-Cherry”, etc.), “Bell” role (design combination “Bell A-Bell A-Bell A”, “Bell B-Bell B-Bell B”, etc.) The number of medals of 2, 2, and 15 is associated. In the medal payment process, the CPU 101 adds the number of medals corresponding to the winning combination to the number of credits, or when the number of credits exceeds 50, drives the medal payout device to pay out to the medal tray 40.

  If the CPU 101 determines that the symbol combination corresponding to the “replay” combination (replaying combination) is stopped and displayed on the winning line L1 by the symbol determination process, the CPU 101 executes an automatic bet process. In the automatic bet processing, the same number as the number of bets for starting the immediately preceding game is set as the number of bets without inserting additional medals or reducing credits.

(5) Details of State Transition Process The details of the state transition process in the slot machine 1 will be described. When the CPU 101 determines that the symbol combination corresponding to the bonus combination (“BB1” combination, “BB2” combination, “RB1” combination, “RB2” combination) is stopped and displayed on the winning line by the symbol determination process. Then, a process of shifting the gaming state to a state corresponding to the bonus combination (BB1 state, BB2 state, RB1 state, RB2 state) is executed.

  Although details are omitted, by shifting the gaming state to the state corresponding to the bonus combination described above, the lottery table corresponding to the bonus combination is controlled in the internal lottery process. In the lottery table corresponding to the bonus combination, the lottery values corresponding to the small combination and the bonus combination are set higher than the lottery table used in the normal gaming state. For this reason, by using such a lottery table, it becomes a more advantageous state than the normal gaming state.

  The gaming state corresponding to the bonus combination described above is controlled so as to end when the number of medals paid out in the gaming state exceeds a predetermined number. That is, control is performed so as to shift from the gaming state corresponding to the bonus combination to the normal gaming state.

<5. Modification>
Each of the above-described embodiments can be variously modified. Specific modifications are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other.

(1) Modification 1
In the above-described form, in the symbol determination process of the slot machine 1, a winning combination is made using a symbol determination table in which one type of symbol combination corresponding to each reel R is associated with one type of symbol combination. Although the example in which the symbol combination stopped and displayed on the line L1 has been described has been described, the present invention is not limited to this.

  For example, using a symbol determination table in which a combination of one type of symbol identification information corresponding to each reel R is associated with a plurality of symbol combinations, the symbol combination stopped and displayed on the winning line L1 is determined. You may do it.

  FIG. 10 is an explanatory diagram for explaining a symbol determination table in which a combination of one type of symbol identification information corresponding to each reel R is associated with a plurality of types of symbol combinations. In this symbol determination table, symbol combinations “bell A-bell A-bell A”, “bell B-bell B-bell B”, “bell A-bell A-bell B”, “bell A-bell B-bell A”. "Bell B-Bell A-Bell A", "Bell A-Bell B-Bell B", "Bell B-Bell A-Bell B" and "Bell B-Bell B-Bell A" Corresponding to a combination of one type of symbol identification information corresponding to each reel R.

  The symbol identification information corresponding to each reel in the symbol determination table is logically ORed with the symbol identification information corresponding to the “Bell A” symbol and the symbol identification information corresponding to the “Bell B” symbol in the symbol identification table. It is defined as a value.

  By defining the symbol identification information in this way, similarly to the symbol determination process described above, based on the logical product of the numerical value of the symbol identification information in the stop symbol information and the numerical value of the symbol identification information in the symbol determination table. Thus, it is possible to determine whether the two symbols match or do not match.

  For example, the symbol identification information corresponding to each reel in the stop symbol information is a value “01000000” (symbol identification information corresponding to “Bell A” symbol) or a value “10000000” (symbol identification information corresponding to “Bell B” symbol). ), The logical product value of the symbol identification information corresponding to the left reel in the symbol determination table is other than 0 and the symbol match is determined, and the symbol identification information of the stop symbol information is a value other than the above (“ In the case of “Bell A” symbol or “Bell B” symbol), the logical product value is 0, and the symbol mismatch is determined.

  Thus, by defining the logical sum of the symbol identification information corresponding to each of a plurality of symbols as the symbol identification information in the symbol determination table, the symbol type indicated by the stop symbol information is the plurality of symbols. It can be determined by calculating the logical product of both symbol identification information.

(2) Modification 2
In the embodiment described above, an example in which no special reference is provided for the order of combination of one symbol identification information (record order) defined in the symbol determination table is described, but the present invention is not limited to this.

  FIG. 11 is an explanatory diagram for explaining a symbol determination table in which the combination order of corresponding symbol identification information is defined in the order of symbol combinations that are likely to be stopped and displayed on the winning line L1.

  The combination of symbol identification information defined in the first to eighth records in this symbol determination table is a symbol combination corresponding to the “replay” role. In the internal lottery table described above, the lottery value corresponding to the “replay” combination is set as the largest value, so that the winning of the “replay” combination is most likely to be determined in the internal lottery process. For this reason, in this symbol determination table, the combination of symbol identification information corresponding to the symbol combination corresponding to the “replay” combination is defined as the top record.

  The combination of symbol identification information defined in the ninth to sixteenth records in this symbol determination table is a symbol combination corresponding to the “bell” combination. In the internal lottery table described above, the lottery value corresponding to the “Bell” role is set as the second largest value after the “Replay” role, so that the winning of the “Bell” role may be determined in the internal lottery process. Is the second highest after the “replay” role. For this reason, in this symbol determination table, a combination of symbol identification information corresponding to the symbol combination corresponding to the “bell” combination is defined as a record after the record corresponding to the “replay” combination.

  There is a possibility that the winning combination is displayed on the winning line L1. The order of the symbol combination is that the winning combination is determined in the internal lottery process, the contents of the stop table used in the reel stopping process, and the reel R. It is determined according to the contents of the symbol array. That is, there is a high possibility that a winning combination is determined in the internal lottery process, a high priority in which the winning combination is displayed on the stop line L1 in the table used when the winning combination is won, and the reel R The possibility of being stopped and displayed on the winning line L1 is determined according to the short arrangement interval of the symbols constituting the symbol combination related to the combination.

(3) Modification 3
In the embodiment described above, an example is described in which the privilege information corresponding to the combination of symbol identification information is defined independently of the symbol identification information combination in the symbol determination table, but the present invention is not limited thereto.

  In the slot machine 1, there are ten types of symbols arranged on the reel R. Therefore, in the symbol identification table described above, the number of digits for 10 digits is used as symbol identification information when expressed in binary. In the slot machine 1, since the unit of data handled by the CPU 101 is composed of 1 byte (8 bits), the symbol identification information for identifying 10 types of symbols requires an information amount of 2 bytes (16 bits). Become. In other words, 6 bits of symbol identification information composed of 2 bytes (16 bits) is not used as information for identifying symbols.

  FIG. 12 is an explanatory diagram for explaining a symbol determination table in which privilege information is defined by being included in symbol identification information. In this symbol determination table, an area that is not used as information for identifying a symbol in one symbol identification information constituting a combination of symbol identification information is assigned as an area for storing privilege information that identifies a privilege type. Yes.

  More specifically, the value “10000” is defined in the lower 5 bits of the symbol identification information corresponding to the right reel in the symbol identification information combination indicating the symbol combination “red 7-red 7-red 7”. Has been. Similarly, among the combinations of symbol identification information indicating each symbol combination, a value indicating the privilege type corresponding to the symbol combination is defined in the lower 5 bits of the symbol identification information corresponding to the right reel.

  Although illustration is omitted, the correspondence relationship between the privilege information as a value indicating the privilege type and the information indicating the content of the privilege is defined as a table different from the symbol determination table, and the correspondence relationship is By referring to the table shown, the content of the privilege can be specified based on the privilege information.

  In the symbol determination table, the value indicated by the privilege information associated with the combination of symbol identification information indicating the symbol combination related to the small combination is the same value as the number of medals to be paid out in the corresponding small combination. Is defined as

  Thus, an unused area as information for identifying a symbol in the symbol identification information may be assigned as an area for storing privilege information for identifying a privilege type.

(4) Modification 4
In the above-described form, each symbol identification information constituting the symbol identification information combination in the symbol determination table is defined as 2-byte data, and one symbol identification information combination is defined as 6-byte data. Not limited to this.

  For example, a combination of one symbol identification information is composed of data of 5 bytes (40 bits), and 10 bits are allocated to symbol identification information for identifying symbols corresponding to each reel R. In this case, the area necessary for storing the symbol identification information corresponding to each reel R is 10 (bits) × 3 (reel) = 30, and is used as information for identifying symbols in the symbol identification information. Since there is an unused area for 10 bits, this area may be used for storing privilege information.

  As described above, the data structure may be appropriately set so that the information for identifying the symbol and the information for identifying the type of privilege are efficiently stored in the storage capacity.
