2. Description of Related Art
There has been known a gaming machine including a plurality of gaming terminals, a terminal controller provided to each gaming terminal and causes the gaming terminal to run a game, a collective control device connected to and in communication with the gaming terminals, and a center controller provided in the collective control device. Such a gaming machine is disclosed, for example, in the specifications of U.S. Pat. No. 5,820,459, U.S. Pat. No. 4,283,709, U.S. Pat. No. 6,003,013, U.S. patent publication No. 2002/0042296, U.S. Pat. No. 6,733,390, U.S. Pat. No. 6,142,872, and U.S. Pat. No. 6,361,441. Each terminal controller independently runs an individual game in the associated gaming terminal, and awards a payout based on the running of the individual game. The center controller determines whether to start a common game commonly run in the plurality of gaming terminals, based on the status of the individual game running in the gaming terminal. Further, the center controller determines the game result of the common game, based on the status of the common game running in the gaming terminal. For example, this common game is a game in which a plurality of players compete against one another to win various types of jackpot such as a progressive jackpot and a mystery jackpot, through a plurality of gaming terminals.
Further, as is disclosed in the specification of U.S. patent publication No. 2009/0005177, a game program (individual game program) used at the time of running the individual game is stored in a storage medium such as CF (CompactFlash®), which is attached to each of the gaming terminals.
The individual game program is loaded from the storage medium to the gaming terminal, and the individual game is run in the gaming terminal, based on the individual game program.
Similarly, a game program (common game program) used at the time of running a common game is also stored in the storage medium such as CF attached to each of the gaming terminals. When the common game program is loaded from the storage medium into the gaming terminal and when the center controller determined to start the common game, the common game is run in each of the gaming terminals, based on the common game program.
However, a game provider (casino owner) is required to change the common game (i.e., common game program) in a short period of time. This is because, for example, players are very much likely to get bored of the common game commonly run in the plurality of gaming terminals.
To change the common game however required exchanging of the storage medium attached to each of the gaming terminals, which is a significant amount of work for the game provider.
It is therefore an object of the present invention to provide a gaming machine which requires a less amount of work for changing a common game which is commonly run in a plurality of gaming terminals, and to provide a communication control method adopted in the gaming machine.
A gaming machine of the present invention includes:
a plurality of gaming terminals each having a terminal-side game information storage device which stores common game information used in a common game commonly run in the plurality of gaming terminals and individual game information used in an individual game individually run in each gaming terminal, an input device which allows an input from the exterior, and a terminal controller;
a collective control device connected to and in communication with the gaming terminals, which has a gaming terminal information storage device storing an accumulated value of trigger values for use in determining a starting condition of the common game in the form of total accumulated value common in the plurality of gaming terminals or in the form of individual accumulated value of each of the gaming terminals, a game information management device for managing the common game information, and a center controller,
wherein the terminal controller is programmed to execute the steps of:
(a1) transmitting a game information requesting command to the collective control device, when booting the gaming terminal;
(a2) storing the common game information received from the collective control device in the terminal-side game information storage device;
(a3) running the individual game in response to an input of start operation through the input device, based on the individual game information stored in the terminal-side game information storage device;
(a4) transmitting a trigger value to the collective control device, every time the individual game is run;
(a5) running the common game in response to a common game starting command from the collective control device, based on the common game information stored in the terminal-side game information storage device; and
(a6) awarding a payout of the common game, based on a game result of the common game from the collective control device,
and wherein the center controller is programmed to execute the steps of:
(b1) transmitting, in response to the game information requesting command from any of the gaming terminals, the common game information managed by the game information management device to that gaming terminal;
(b2) when a trigger value is received from any of the gaming terminals, adding the trigger value to the total accumulated value or the individual accumulated value stored in the gaming terminal information storage device of the gaming terminal having transmitted the trigger value;
(b3) transmitting to the plurality of gaming terminals a common game starting command for starting the common game in each of the gaming terminals, when the total accumulated value or the individual accumulated value of any one of the gaming terminals stored in the gaming terminal information storage device reaches a predetermined threshold;
(b4) determining a game result of the common game in each gaming terminal, based on the status of the common game running; and
(b5) transmitting the game results of the common game to the plurality of gaming terminals.
In the above structure, the terminal controller transmits the game information requesting command to the collective control device, when the gaming terminal is booted. The center controller transmits, to the gaming terminal, the common game information managed by the game information management device, in response to the game information requesting command from the gaming terminal. The terminal controller stores the common game information received from the collective control device, in the terminal-side game information storage device. Meanwhile, the terminal controller transmits a trigger value to the collective control device, every time the individual game is run. When the trigger value is received from any of the gaming terminals, the center controller adds the trigger value to the total accumulated value or the individual accumulated value stored in the gaming terminal information storage device of the gaming terminal having transmitted the trigger value. When the total accumulated value or the individual accumulated value of any one of the gaming terminals reaches a predetermined threshold, the center controller transmits to the plurality of gaming terminals a common game starting command for starting the common game in each gaming terminal. The terminal controller runs the common game based on the common game information stored in the terminal-side game information storage device, in response to the common game starting command from the collective control device. Thus, simply changing the common game information managed by the game information management device of the collective control device changes the common game information of all the gaming terminals connected and in communication with the collective control device. This reduces the work required for changing the common game information for use in the common game. Further, the common game information is received from the collective control device, at the time of booting the gaming terminal. The gaming terminal therefore is able to run the common game based on the common game information, immediately after the reception of the common game starting command from the collective control device.
A gaming machine of the present invention includes:
a plurality of gaming terminals each having a terminal-side game information storage device which stores common game information used in a common game commonly run in the plurality of gaming terminals and individual game information used in an individual game individually run in each gaming terminal, an input device which allows an input from the exterior, and a terminal controller;

(c4) running the common game in response to a common game starting command from the collective control device, based on the common game information stored in the terminal-side game information storage device; and
(c5) awarding a payout of the common game, based on a game result of the common game from the collective control device,
and wherein the center controller is programmed to execute the steps of:
(d1) transmitting, in response to the game information requesting command from any of the gaming terminals, the common game information managed by the game information management device to that gaming terminal;
(d2) determining whether or not a common game starting condition is met, based on the status of the individual game running in the gaming terminal;
(d3) when the common game starting condition is met, transmitting the common game starting command to the plurality of gaming terminals;
(d4) determining a game result of the common game in each gaming terminal, based on the status of the common game running; and
(d5) transmitting the game results of the common game to the plurality of gaming terminals.
In the above structure, the terminal controller transmits the game information requesting command to the collective control device, when the gaming terminal is booted. The center controller transmits, to the gaming terminal, the common game information managed by the game information management device, in response to the game information requesting command from the gaming terminal. The terminal controller stores the common game information received from the collective control device, in the terminal-side game information storage device. Further, the center controller determines whether or not the common game starting condition is met, based on the status of the individual game running in the gaming terminal. When the common game starting condition is met, the center controller transmits the common game starting command to the plurality of gaming terminals. The terminal controller runs the common game based on the common game information stored in the terminal-side game information storage device, in response to the common game starting command from the collective control device. Thus, simply changing the common game information managed by the game information management device of the collective control device changes the common game information of all the gaming terminals connected and in communication with the collective control device. This reduces the work required for changing the common game information for use in the common game. Further, the common game information is received from the collective control device, at the time of booting the gaming terminal. The gaming terminal therefore is able to run the common game based on the common game information, immediately after the reception of the common game starting command from the collective control device.
A gaming machine of the present invention includes:
a plurality of gaming terminals each having a terminal-side game information storage device which stores common game information used in a common game commonly run in the plurality of gaming terminals, identification information corresponding to the common game information, and individual game information used in an individual game individually run in each gaming terminal, an input device which allows an input from the exterior, and a terminal controller;

(e4) running the common game in response to a common game starting command from the collective control device, based on the common game information stored in the terminal-side game information storage device; and
(e5) awarding a payout of the common game, based on the game result of the common game from the collective control device,
and wherein the center controller is programmed to execute the steps of:
(f1) receiving the game information requesting command from the gaming terminal, and determining whether the identification information contained in the game information requesting command and the identification information managed by the game information management device match with each other;
(f2) only when it is determined that the pieces of identification information do not match with each other in (f1), transmitting the common game information and the identification information corresponding to the common game information, the common game information and the identification information being managed by the game information management device, to the gaming terminal having transmitted the game information requesting command;
(f3) determining whether or not a common game starting condition is met, based on the status of the individual game running in the gaming terminal;
(f4) when the common game starting condition is met, transmitting the common game starting command to the plurality of gaming terminals;
(f5) determining the game result of the common game based on the state of the common game running in the gaming terminal;
(f6) transmitting the game results of the common game to the plurality of gaming terminals.
In the above structure, the terminal controller transmits to the collective control device the game information requesting command containing the identification information stored in the terminal-side game information storage device, when the gaming terminal is booted. The center controller determines whether the identification information contained in the game information requesting command from the gaming terminal matches with the identification information managed by the game information management device. Only if the two pieces of identification information do not match with each other, the center controller transmits the common game information and the identification information managed by the game information management device to the gaming terminal. The terminal controller stores the common game information received from the collective control device, in the terminal-side game information storage device. Further, the center controller determines whether or not the common game starting condition is met, based on the status of the individual game running in the gaming terminal. When the common game starting condition is met, the center controller transmits the common game starting command to the plurality of gaming terminals. The terminal controller runs the common game based on the common game information stored in the terminal-side game information storage device, in response to the common game starting command from the collective control device. Thus, simply changing the common game information managed by the game information management device of the collective control device changes the common game information of all the gaming terminals connected and in communication with the collective control device. This reduces the work required for changing the common game information for use in the common game. Further, the collective control device transmits the common game information to the gaming terminal, only when the common game information stored in the terminal-side game information storage device of the gaming terminal and the common game information managed by the game information management device of the collective control device do not match with each other. This reduces the work for changing the common game information. Further, the common game information is received from the collective control device, at the time of booting the gaming terminal. The gaming terminal therefore is able to run the common game based on the common game information, immediately after the reception of the common game starting command from the collective control device.
A communication control method of the present invention is for use in a gaming machine including: a plurality of gaming terminals each having a terminal-side game information storage device which stores common game information used in a common game commonly run in the plurality of gaming terminals and individual game information used in an individual game individually run in each gaming terminal, and an input device which allows an input from the exterior; a collective control device connected to and in communication with the gaming terminals, which has a gaming terminal information storage device storing an accumulated value of trigger values for use in determining a starting condition of the common game in the form of total accumulated value common in the plurality of gaming terminals or in the form of individual accumulated value of each of the gaming terminals, and a game information management device for managing the common game information,
wherein the gaming terminal is programmed to execute the steps of:

determining a game result of the common game in each gaming terminal, based on the status of the common game running; and
transmitting the game results of the common game to the plurality of gaming terminals.
In the above structure, the gaming terminal transmits the game information requesting command to the collective control device, when the gaming terminal is booted. The collective control device transmits, to the gaming terminal, the common game information managed by the game information management device, in response to the game information requesting command from the gaming terminal. The gaming terminal stores the common game information received from the collective control device, in the terminal-side game information storage device. Meanwhile, the terminal controller transmits a trigger value to the collective control device, every time the individual game is run. When the trigger value is received from any of the gaming terminals, the collective control device adds the trigger value to the total accumulated value or the individual accumulated value stored in the gaming terminal information storage device of the gaming terminal having transmitted the trigger value. When the total accumulated value or the individual accumulated value of any one of the gaming terminals reaches a predetermined threshold, the collective control device transmits to the plurality of gaming terminals a common game starting command for starting the common game in each gaming terminal. The gaming terminal runs the common game based on the common game information stored in the terminal-side game information storage device, in response to the common game starting command from the collective control device. Thus, simply changing the common game information managed by the game information management device of the collective control device changes the common game information of all the gaming terminals connected and in communication with the collective control device. This reduces the work required for changing the common game information for use in the common game. Further, the common game information is received from the collective control device, at the time of booting the gaming terminal. The gaming terminal therefore is able to run the common game based on the common game information, immediately after the reception of the common game starting command from the collective control device.
As shown in
Specifically, the gaming machine 300 includes: the plurality of slot machines 10 each having a terminal-side game information storage device which stores common game information used in a common game commonly run in the plurality of slot machines 10 and individual game information used in an individual game individually run in each gaming terminal, an input device which allows an input from the exterior, and a terminal controller programmed to perform the following steps (a1) to (a6); the external controller 200 connected to and in communication with the slot machines 10, which has a gaming terminal information storage device storing an accumulated value of trigger values for use in determining a starting condition of the common game in the form of total accumulated value common in the plurality of slot machines 10 or in the form of individual accumulated value of each of the slot machines 10, a game information management device for managing the common game information, and a center controller programmed to perform the following steps (b1) to (b5).
The steps step (a1) to (a6) performed by the terminal controller of each slot machine 10 is described. Step (a1) is a step for transmitting a game information requesting command to the external controller 200, when booting the slot machine 10. The “game information requesting command” is a command that requests transmission of the common game information managed in the game information management device to the slot machine 10. The “common game information” is a game program used when performing the common game in each slot machine 10.
Step (a2) is a step for storing the common game information received from the external controller 200 in the terminal-side game information storage device. Step (a3) is a step for running the individual game in response to an input of start operation through the input device, based on the individual game information stored in the terminal-side game information storage device. The “individual game information” is a game program used when the individual game is run.
Step (a4) is for transmitting a trigger value to the external controller 200, every time the individual game is run. The “trigger value” is a value for determining whether a starting condition of the common game is met. This trigger value is, for example, a game value such as an amount of bet placed in the individual game, or the number of times the individual game has been played.
Step (a5) is for running the common game in response to a common game starting command from the external controller 200, based on the common game information stored in the terminal-side game information storage device. The common game may be run in place of the individual game, or the individual game and the common game may be run in parallel.
Step (a6) is a step for awarding a payout of the common game, based on a game result of the common game from the external controller 200.
Next, the steps step (b1) to (b5) performed by the external controller 200 is described. Step (b1) is a step for transmitting, in response to the game information requesting command from any of the slot machine 10, the common game information managed by the game information management device to that slot machine 10. Step (b2) is a step for, when a trigger value is received from any of the slot machines 10, adding the trigger value to the total accumulated value or the individual accumulated value stored in the gaming terminal information storage device of the slot machine 10 having transmitted the trigger value.
The “total accumulated value” is an accumulated value of the trigger values transmitted from the plurality of slot machines 10 connected to and in communication with the external controller 200, and is stored in the gaming terminal information storage device of the external controller 200. Further, the “individual accumulated value” is an accumulated value of the trigger values for each of the slot machines 10, and is stored in the gaming terminal information storage device of the external controller 200, in association with each of the slot machines 10. In other words, the number of individual accumulated values is the same as the number of slot machines 10 connected to and in communication with the external controller 200.
Step (b3) is a step for transmitting to the plurality of slot machines 10 a common game starting command for starting the common game in each of the slot machines 10, when the total accumulated value stored in the gaming terminal information storage device or the individual accumulated value of any one of the slot machines 10 reaches a predetermined threshold. Step (b4) is a step for determining a game result of the common game in each slot machine 10, based on the status of the common game running. Step (b5) is a step for transmitting the game results of the common game to the plurality of slot machines 10.
Each of the “slot machines 10” is a type of gaming terminal in the gaming machine 300. Note that the present embodiment is described using slot machines 10 as an example of gaming terminals; however, the present invention is not limited to this: The present invention may adopt a model which has a terminal controller capable of independently running an individual game.
The “individual game” in the present invention is a game run in the slot machine 10, based on the individual game information. The individual game is a slot game where a plurality of symbols 501 are rearranged. Note that the individual game is not limited to slot game: The base game may be any type as long as it is independently runnable in gaming terminals such as slot machines 10. Further, in the present embodiment, there are two types of individual games: the base game and the bonus game. However, the base game is not limited to these two types.
Rearrangement of the symbols 501 in the slot game is performed at a symbol display region 4. The slot game includes: running of a base game in which symbols 501 are rearranged in the symbol display region 4 on the premise that a game value is bet and a base payout is awarded according to the symbols 501 rearranged; and running of a bonus game with a higher payout ratio than the base game, in which symbols 501 are rearranged when the symbols 501 rearranged in the base game 501 meet a predetermined condition, and awards a bonus payout according to the symbols 501 rearranged.
The “game value” is a coin, bill, or electrically valuable information corresponding to these. Note that the game value in the present invention is not particularly limited. Examples of the game value include game media such as medals, tokens, cyber money, tickets, and the like. A ticket is not particularly limited, and a later-mentioned ticket with a barcode may be adopted for example.
The “bonus game “has a same meaning as a” feature game”. In the present embodiment, the bonus game is a game in which a free game is repeated. However, the bonus game is not particularly limited and may be any type of game, provided that the bonus game is more advantageous than the base game for a player. Another bonus game may be adopted in combination, provided that a player is given a more advantageous playing conditions than the base game. For example, the bonus game may be a game that provides a player with a chance of winning more game values than the base game or a game that provides a player with a higher chance of winning game values than the base game. Alternatively, the bonus game may be a game that consumes fewer amounts of game values than the base game. In the bonus game, these games may be provided alone or in combination.
The “free game” is a game runnable with a bet of fewer game values than the base game. Note that “bet of fewer game values” encompasses a bet of zero game value. The “free game” therefore may be a game runnable without a bet of game value, which awards an amount of game value based on symbols 501 rearranged. In other words, the “free game” may be a game which is started without the premise that a game value is consumed. To the contrary, the “base game” is a game runnable on condition that a game value is bet, which awards an amount of game value based on symbols 501 rearranged. In other words, the “base game” is a game which starts on the premise that a game value is consumed.
The expression “rearrange” means dismissing an arrangement of symbols 501, and once again arranging symbols 501. The expression “arrangement” means a state of symbols 501, which can be visibly confirmed by a player.
The “common game” is a game commonly run in the plurality of slot machines 10. This common game is run in each slot machine 10, in response to a common game starting command from the external controller 200, based on the common game information stored in the terminal-side game information storage unit 654. The external controller 200 determines the game result of the common game based on the status of the common game running in the slot machines 10, and transmits game result information indicative of the game result to the slot machines 10. The slot machine 10 is awards a payout of the common game, according to the game result information from the external controller 200.
Specifically, the common game of the present embodiment is as follows. First, in each of the slot machines 10, the a plurality of symbols 180 for the common game are rearranged in the symbol display region 4. If the plurality of symbols 180 rearranged forms a winning combination of the common game, the states of light emitting portions 403 of a path 401 associated with the slot machine 10 having achieved the winning combination are serially changed, starting from a position 402 to a common game payout display unit 400. When the states of the light emitting portions 403 are changed all the way to the common game payout display unit 400, the slot machine associated with the path 401 awards a payout of the common game. This is the overview of the common game related to the present embodiment. The common game of the present invention is not limited to the one described above, and may be any given game such as craps game or the like, provided that the common game is commonly run in the plurality of slot machines 10.

(Operation of Gaming Machine 300)
With reference to a flowchart of
(Operation of Slot Machine 10)
The slot machine 10 serving as a gaming terminal carries out terminal-side processes (A1) to (A9). Specifically, the boot of the gaming terminal is detected (step A1). Then, a game information requesting command is transmitted to the external controller 200 (step A2). Note that, if the terminal-side game information storage unit 654 stores the common game information, the identification information corresponding to the common game information may be transmitted to the external controller 200.
Next, the common game information is received from the external controller 200, and the common game information is stored in the terminal-side game information storage unit 654 (step A3).
Next, the slot machine 10 runs the base game based on the individual game information stored in the terminal-side game information storage unit 654 (step A3). Specifically, a series of the following operations are performed.
(Coin-Insertion/Start-Check)
First, the slot machine 10 checks if the bet button unit 601 is pressed by a player, and if the spin button unit 602 is subsequently pressed by the player.
(Symbol Determination)
Next, when the player presses the spin button unit 602, the slot machine 10 extracts a random number for symbol determination. Then, for each video reel displayed on the display unit 614, the slot machine 10 determines symbols 501 to be presented to the player when scrolling of symbol columns is stopped.
(Symbol Display)
Next, the slot machine 10 starts scrolling a symbol column of each video reel, and stops the scroll so that the symbols 501 determined are presented to the player.
(Winning Determination)
Next, when the symbol column of each video reel stops scrolling, the slot machine 10 determines whether a combination of the symbols 501 presented to the player relates to a winning.
(Payout)
When the combination of symbols 501 displayed for the player is a combination related to winning, the slot machine 10 offers benefits according to the combination to the player.
For example, when a combination of symbols 501 which relates to a payout of one or more coins, the slot machine pays out the number of coins according to the combination of symbols 501.
Next, whether a bonus combination is formed is determined. When a bonus combination is formed, a bonus game process is run. Meanwhile, when no bonus combination is formed, a base game is run again. During a period of time where the individual game including a base game and a bonus game is run, running status information is transmitted to the external controller 200, the running status information indicating a start and an end of a regular game and the bet amount on a unit game of the base game or the like. This allows the external controller 200 to perform centralized control of each slot machine 10.
Next, the slot machine 10 transmits a trigger value to the external controller 200 for each unit base game (step A5). Next, the slot machine 10 determines whether or not a common game starting command is received from the external controller 200 (step A6).
When the slot machine 10 determines that no common game starting command is received (step A6: NO), the slot machine 10 returns to the process of step A4. On the other hand, when the slot machine 10 determines that the common game starting command is received (step A6: YES), the slot machine 10 runs the common game based on the common game information stored in the terminal-side game information storage unit 654 (step A7).
Next, the slot machine 10 receives the game result information of the common game from the external controller 200 (step A8), and awards a payout based on the game result information of the common game (step A9).
(Operation of External Controller 200)
The external controller 200 runs the following center-side processes of (B1) to (B8) in synchronization with the slot machines 10, while the slot machines 10 are being in operation as described above.
First, the external controller 200 receives the game information requesting command from the slot machine 10 (step B1), and transmits the common game information to the slot machine 10 having transmitted the game information requesting command (step B2). Note that, when the identification information contained in the game information requesting command and the identification information stored in the game information management unit 6212 match with each other, the common game information does not have to be transmitted.
Next, the external controller 200 receives a trigger value from the slot machine 10, and accumulatively adds to the total accumulated value or to the individual accumulated value stored in the gaming terminal information storage unit 6211, the individual accumulated value corresponding to the slot machine 10 having transmitted the trigger value (step B3).
Next, the external controller 200 determines whether or not the total accumulated value or the individual accumulated value stored in the gaming terminal information storage unit 6211 has reached a predetermined threshold (step B4). When the external controller 200 determines that the accumulated value has not yet reached the threshold (step B4: NO), the process returns to step B3. On the other hand, when the external controller 200 determines that the accumulated value has reached the threshold (step B4: YES), the external controller 200 transmits a common game starting command to the plurality of slot machines 10 connected and in communication with the external controller 200 (step B5).
Next, the external controller 200 obtains the status of the common game running from each of the slot machines 10 (step B6), and determines the game result of the common game based on that the status obtained (step B7). Next, the external controller 200 transmits to the plurality of slot machines 10 the game result information indicative of the game result of the common game (step B8).
As described above, the gaming machine 300 includes the slot machines 10 and the external controller 200, each of which slot machines 10 carries out the terminal-side process of (A1) to (A9), and the external controller 200 carries out the center-side processes of (B1) to (B8).
Thus, changing the common game information managed by the game information management device of the external controller 200 will change the common game information of all the slot machines 10 connected and in communication with the external controller 200. This reduces the work required for changing the common game information for use in the common game. Further, the common game information is received from the external controller 200 at the time of booting the slot machine 10. Therefore, the slot machine 10 is able to run the common game based on the common game information immediately after the common game starting command is received from the external controller 200.

The circuit structure of the gaming machine has been described above. Next, with reference to
A first video reel 3a, a second video reel 3b, a third video reel 3c, a fourth video reel 3d, and a fifth video reel 3e each is assigned with a symbol column consisting of 22 symbols that correspond to respective code numbers from “00” to “21”.
Types of the symbols provided are “BLUE 7”, “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM”, “ORANGE” and “APPLE”.
[Symbol Combination Table for Individual Game]
Next, with reference to
The symbol combination table specifies combinations of drawn symbols relating to winning, and the number of payouts. On the slot machine 10, the scrolling of symbol columns of the respective video reels 3 is stopped, and winning is established when the combination of symbols displayed along the winning line L matches one of the combinations of symbols specified by the symbol combination table. According to the winning combination, a benefit such as payout of coins or start of a bonus game is offered to the player. It is to be noted that winning is not established (i.e. the game is lost) when the combination of symbols displayed along the winning line L does not match any of the combinations of symbols specified by the symbol combination table.
Basically, winning is established when all symbols displayed along the winning line L by the respective video reels 3 are of one type out of, “APPLE”, “BLUE 7”, “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM” and “ORANGE”. However, with respect to the respective types of symbols of “CHERRY” and “ORANGE”, winning is also established when one or three symbols of either type are displayed along the winning line L by the video reels 3. For example, when all the symbols displayed along the winning line L by all the video reels 3 are “BLUE 7”, the winning combination is “BLUE”, and “10” is determined as the number of payouts. Based on the determined number of payouts, payout of coins is performed. The payout of coins is performed by actually discharging coins from the coin payout exit 15A or adding the determined number of payouts to the number of credits, or issuing a ticket with a barcode.
“APPLE” is a symbol related to the bonus game trigger. When all the symbols displayed along the winning line L by all the video reels 3 are “APPLE”, the winning combination is “bonus game trigger”, and bonus games start from the next game.
[Common Game]
Next, the following schematically describes the common game of the embodiment of the present invention, with reference to
The common game starts when the total accumulated value or the individual accumulated value stored in the RAM 243 of the external controller 200 reaches the threshold. During the common game, the a plurality of symbols 180 of the common game is rearranged in the symbol display region 4 of each slot machine 10. When a predetermined winning combination is achieved by the plurality of symbols 180 rearranged in any slot machine 10, the status of the light emitting portions 403 changes serially from the position 402 corresponding to that slot machine 10 towards the common game payout display unit 400. This operation is repeated until the status of the plurality of light emitting portions 403 in any one of the paths 401 changes all the way up to the common game payout display unit 400. Note that the light emitting portions 403 whose respective states changed from the non-lighting state to the lighting state are denoted by the reference numeral 403a. The light emitting portions 403b are the light emitting portions 403 whose respective states have not changed.
As shown in
[Symbol Columns of Video Reels for Common Game]
Next, with reference to
A first video reel 3a, a second video reel 3b, a third video reel 3c, a fourth video reel 3d, and a fifth video reel 3e each is assigned with a symbol column including 22 symbols that correspond to respective code numbers from “00” to “21”, as in the case of symbol columns of
The types of symbol include: “Angelfish”, “Clownfish”, “7”, “Tuna”, and “Coelacanth”.
[Symbol Combination Table for Common Game]
Next, with reference to
The symbol combination table for the common game defines the combinations of symbols related to a winning, the number of payouts, and the number of light emitting portions 403 whose respective states are changed serially towards the common game payout display unit 400. On the slot machine 10, the scrolling of symbol columns of the respective video reels 3 is stopped, and winning is established when the combination of symbols displayed along the winning line L matches one of the combinations of symbols specified by the symbol combination table for the common game. According to the winning combination, a benefit such as payout of coins is offered to the player. It is to be noted that winning is not established (i.e. the game is lost) when the combination of symbols displayed along the winning line L does not match any of the combinations of symbols specified by the symbol combination table.
A winning is achieved when three or more of the same symbol out of “Angelfish”, “Clownfish”, “7”, “Tuna”, and “Coelacanth” are displayed on the winning line L. For example, if three “Angelfish” symbols are displayed on the winning line L, the number of payouts is determined as to be “12” and the number of light emitting portions 403 whose respective states are serially changed towards the common game payout display unit 400 is determined as to be “6”. Based on the determined number of payouts, payout of coins is performed. Further, the states of six light emitting portions 403 in the path 401 corresponding to that slot machine 10 are changed.
[Contents of Program]
The symbol combination table for the common game has been described above. Next, with reference to
<Terminal-Side Process>
First described with reference to
First, the main CPU 71 detects a boot of the slot machine 10 (step A11). Next, the authenticated game system program, a unit game program (the individual game information), and the common game program are read out from the GPCF 57 and the GSCF 58 via the gaming board 50, and are written into the RAM 73 (step A12).
Next, the main CPU 71 performs a terminal-side game information transmission/reception process which is described layer with reference to
Next, the main CPU 71 performs an individual game running process which is described later with reference to
<Terminal-Side Game Information Transmission/Reception Process>
Next, with reference to
First, the main CPU 71 starts a download program for receiving the common game information from the external controller 200 (step A81), and performs a download request in which a game information requesting command containing the identification information of the common game information stored in the RAM 73 is transmitted to the external controller 200 (step A82). Note that, if RAM 73 stores no common game information, the game information requesting command transmitted to the external controller 200 contains information that no common game information is stored.
Next, the main CPU 71 determines whether or not update command information is received from the external controller 200 (step A83). The update command information indicates whether to update the common game information stored in the RAM 73. If the main CPU 71 determines that no update command information is received (step A83: NO), the process returns to step A83.
On the other hand is the main CPU 71 determines that the update command information is received (step A83: YES), the main CPU 71 determines whether to update the common game information stored in the RAM 73, based on the update command information (step A84). When the main CPU 71 determines not to update the common game information (step A84: NO), this process routine ends.
On the other hand, when the main CPU 71 determines to update the common game information (step A84: YES), the main CPU 71 enters the standby mode to wait for the common game information file from the external controller 200 (step A85). Next, the main CPU 71 determines whether or not a common game information file is received from the external controller 200 (step A86). When the main CPU 71 determines that no common game information files is received (step A86: NO), the process returns to step A85. On the other hand, when the main CPU 71 determines that a common game information file is received (step A86: YES), the main CPU 71 performs a file saving process to store the file in the RAM 73 (step A87).
Next, the main CPU 71 determines whether or not a transmission end signal indicating the transmission end of the common game information file is received from the external controller 200 (step A88). When the main CPU 71 determines that no transmission end signal is received (step A88: NO), the process returns to step A85.
On the other hand, if the main CPU 71 determines that the transmission end signal is received (step A88: YES), the main CPU 71 performs a signature checking whereby the signature is extracted from the common game information file (step A89). The signature extracted is then transmitted to the external controller 200 as a resulting signature (step A90).
Next, the main CPU 71 ends the download program (step A91), and starts the game program (step A92).
Next, the main CPU 71 determines whether or not a signature determination result is received from the external controller 200 (step A93), the signature determination result indicating the presence of any fraud such as tampering of data in the file during the communication between the slot machine 10 and the external controller 200. When the main CPU 71 determines that the signature determination result is not received (step A93: NO), the process returns to step A93.
On the other hand, when the main CPU 71 determines that the signature determination result is received (step A93: YES), the main CPU 71 determines whether or not the signature determination result indicates that the common game information file received from the external controller 200 is a fraud-free file (step A94). When the main CPU 71 determines that the common game information file is fraud-free (step A94:YES), the main CPU 71 ends this process routine. On the other hand, when the main CPU 71 determines that the common game information file is not fraud-free (step A94:NO), the main CPU 71 prohibits running of the common game based on the common game information file (step A95), and the process returns to step A81.
<Individual Game Running Process>
Next, with reference to
First, the main CPU 71 performs an at-one-game-end initialization process (step S12). For example, data that becomes unnecessary after each game in the working areas of the RAM 73, such as the number of BETs and the symbols determined by lottery, is cleared.
Next, the main CPU 71 performs a coin-insertion/start-check process which is described later with reference to
Next, the main CPU 71 performs a symbol lottery process which is described later with reference to
Next, the main CPU 71 performs a mystery bonus lottery process (step S15). In the process, lottery determining whether or not to establish a mystery bonus trigger is held. For example, the main CPU 71 extracts a random number for mystery bonus from the numbers in a range of “0 to 99”, and establishes the mystery bonus trigger when the extracted random number is “0”.
The main CPU 71 performs an effect contents determination process (step S16). The main CPU 71 extracts a random number for effect, and determines any of the effect contents from the preset plurality of effect contents by lottery.
The main CPU 71 then performs a symbol display control process which is described later with reference to
Next, the main CPU 71 performs a number-of-payouts determination process which is described later with reference to
The main CPU 71 then determines whether or not the bonus game trigger has been established (step S19). When the main CPU 71 determines that the bonus game trigger has been established (step S19: YES), the main CPU 71 performs a bonus game process which is described later with reference to
After the process of step S20 or when determining in step S19 that the bonus game trigger has not been established (step S19: NO), the main CPU 71 determines whether or not the mystery bonus trigger is established (step S21). When determining that the mystery bonus trigger has been established (step S21: YES), the main CPU 71 performs the mystery bonus process (step S22). In the process, the number of payouts (e.g. 300) being set for the mystery bonus is stored into the number-of-payouts storage area provided in the RAM 73.
After the process of step S22 or when determining in step S21 that the mystery bonus trigger has not been established (step S21: NO), the main CPU 71 performs an insurance-check process which is described later with reference to
The main CPU 71 performs a payout process (step S24). The main CPU 71 adds the value stored in the number-of-payouts storage area to a value stored in a number-of-credits storage area provided in the RAM 73. It is to be noted that operations of the hopper 113 may be controlled based on input from the CASHOUT switch 33S, and coins of the number corresponding to the value stored in the number-of-payouts storage area may be discharged from the coin payout exit 15A. Further, operations of the ticket printer 171 may be controlled and a ticket with a barcode may be issued on which a value stored in the number-of-payouts storage area is recorded. The individual game running process ends after this process.
<Coin-Insertion/Start-Check Process>
Next, with reference to
First, the main CPU 71 determines whether or not insertion of a coin has been detected by the coin counter 92C (step S41). When determining that the insertion of a coin has been detected (step S41: YES), the main CPU 71 makes an addition to the value stored in the number-of-credits storage area (step S42). It is to be noted that, in addition to the insertion of a coin, the main CPU 71 may determine whether or not insertion of a bill has been detected by the bill validator 115, and when determining that the insertion of a bill has been detected, the main CPU 71 may add a value according to the bill to the value stored in the number-of-credits storage area.
After step S42 or when determining in step S41 that the insertion of a coin has not been detected (step S41: NO), the main CPU 71 determines whether or not the value stored in the number-of-credits storage area is zero (step S43). When the main CPU 71 determines that the value stored in the number-of-credits storage area is not zero (step S43: NO), the main CPU 71 permits operation acceptance of the BET buttons (step S44).
Next, the main CPU 71 determines whether or not operation of any of the BET buttons has been detected (step S45). When the main CPU 71 determines that the BET switch has detected press of the BET button by the player, the main CPU 71 makes an addition to a value stored in a number-of-BETs storage area provided in the RAM 73 and makes a subtraction from the value stored in the number-of-credits storage area, based on the type of the BET button (step S46).
The main CPU 71 then determines whether or not the value stored in the number-of-BETs storage area is at its maximum (step S47). When the main CPU 71 determines that the value stored in the number-of-BETs storage area is at its maximum (step S47: YES), the main CPU 71 prohibits updating of the value stored in the number-of-BETs storage area (step S48). After step S48 or when determining in step S47 that the value stored in the number-of-BETs storage area is not at its maximum (step 47: NO), the main CPU 71 permits operation acceptance of the spin button (step S49).
After step S49 or when determining in step S45 that the operation of any of the BET buttons has not been detected (step S45: NO), or when determining in step S43 that the value stored in the number-of-credits storage area is zero (step S43: YES), the main CPU 71 determines whether or not operation of the spin button has been detected (step S50). When the main CPU 71 determines that the operation of the spin button has not been detected (step S50: NO), the process is shifted to step S41.
When the main CPU 71 determines that the operation of the spin button has been detected (step S50: YES), the main CPU 71 performs a jackpot-related process which is described later with reference to
Next, the main CPU 71 performs an insurance-related process which is described later with reference to
<Jackpot-Related Process>
Now, with reference to
First, the main CPU 71 calculates the trigger value (step S71). The main CPU 71 obtains the product of the value stored in the number-of-BETs storage area and a preset accumulation ratio, to calculate the trigger value. In the present embodiment, the trigger value is calculated based on the number of BETs; however, the trigger value is not limited to this.
Next, the main CPU 71 transmits the calculated trigger value to the external controller 200 (step S72).
<Insurance-Related Process>
Next, with reference to
First, the main CPU 71 determines whether or not an insurance-effective flag is turned on (step S91). The insurance-effective flag is turned on when a command to make the insurance effective is inputted by the player in the insurance selection process which is described later with reference to
When the main CPU 71 determines that the insurance-effective flag is not turned on (step S91: NO), the main CPU 71 completes the insurance-related process. On the other hand, when the main CPU 71 determines that the insurance-effective flag is turned on (step S91: YES), the main CPU 71 updates a value stored in a number-of-games storage area for insurance provided in the RAM 73 (step S92). The number-of-games storage area for insurance is an area for storing the number of games up to the time of the payout by the insurance. In the process of step S92, the main CPU 71 adds one to the value stored in the number-of-games storage area for insurance. After the process has been performed, the insurance-related process is completed.
<Symbol Lottery Process>
Next, with reference to
First, the main CPU 71 extracts random numbers for symbol determination (step S111). The main CPU 71 then determines to-be stopped symbols for the respective video reels 3 by lottery (step S112). The main CPU 71 holds a lottery for each video reel 3, and determines any one of the 22 symbols (code numbers from “00” to “21”) as a to-be stopped symbol. At this time, each of the 22 symbols (code numbers from “00” to “21”) is determined at an equal probability (i.e. 1/22).
The main CPU 71 then stores the determined to-be stopped symbols for the respective video reels 3 into a symbol storage area provided in the RAM 73 (step S113). Next, the main CPU 71 refers to the symbol combination table (
<Symbol Display Control Process>
Next, with reference to
First, the main CPU 71 starts scrolling of the symbol columns of the respective video reels 3 that are displayed to the symbol display region 4 of the lower image display panel 141 (step S131). The main CPU 71 then stops the scrolling of the symbol columns of the respective video reels 3, based on the aforementioned symbol storage area (step S132). After the process has been performed, the symbol display control process is completed.
<Number-of-Payouts Determination Process>
Next, with reference to
First, the main CPU 71 determines the number of payouts corresponding to the winning combination (step S152). For example, when the winning combination is “BELL” in the individual game, the main CPU 71 determines “8” as the number of payouts (see
<Insurance-Check Process>
Next, with reference to
First, the main CPU 71 determines whether or not the insurance-effective flag is turned on (step S171). When the main CPU 71 determines that the insurance-effective flag is not turned on (step S171: NO), the main CPU 71 completes the insurance-check process.
When the main CPU 71 determines that the insurance-effective flag is turned on (step S171: YES), the main CPU determines whether or not a predetermined winning combination has been established (step S172). In the present embodiment, “bonus game trigger”, and “mystery bonus” are subjects of the predetermined winning combination.
When the main CPU 71 determines that the predetermined winning combination has not been established (step S172: NO), the main CPU 71 determines whether or not the value stored in the number-of-games storage area for insurance has reached a predetermined number of times (e.g. 300) (step S173). When the main CPU 71 determines that the value stored in the number-of-games storage area for insurance has not reached the predetermined number of times (step S173: NO), the main CPU 71 completes the insurance-check process.
When the main CPU 71 determines that the value stored in the number-of-games storage area for insurance has reached the predetermined number of times (step S173: YES), the main CPU 71 performs a payout process based on the amount of insurance (step S174). The main CPU 71 adds an amount (e.g. 200) previously set as the amount of insurance to the value stored in the number-of-credits storage area.
After step S174 or when determining in step S172 that the predetermined winning combination has been established (step S172: NO), the main CPU 71 resets the value stored in the number-of-games storage area for insurance (step S175). Next, the main CPU 71 turns the insurance-effective flag off (step S176). After the process has been performed, the insurance-check process is completed.
<Bonus Game Process>
Next, with reference to
The main CPU 71 first determines the number of bonus games (step S191). The main CPU 71 extracts a random number for number-of-bonus-games determination, and determines any one of the various numbers of bonus games such as “50”, “70” and “100” by lottery.
Next, the main CPU 71 stores the determined number of bonus games into a number-of-bonus-games storage area provided in the RAM 73 (step S192).
The main CPU 71 then performs an at-one-game-end initialization process in the same way as the process of step S12 described with reference to
Next, the main CPU 71 determines whether or not the bonus game trigger has been established (step S198). When the main CPU 71 determines that the bonus game trigger has been established (step S198: YES), the main CPU 71 determines the number of bonus games to be added (step S199). In the same way as the aforementioned process of step S191, the main CPU 71 determines the number of bonus games. The main CPU 71 then adds the determined number of bonus games to the value stored in the number-of-bonus-games storage area (step S200).
After the process of step S200 or when determining in step S198 that the bonus game trigger has not been established (step S198: NO), the main CPU 71 performs the payout process (step S201). In the payout process, the main CPU 71 adds the value stored into the number-of-payouts storage area in the aforementioned number-of-payouts determination process of step S197 to a value stored in a number-of-payouts storage area for bonus. The number-of-payouts storage area for bonus is an area for storing a total of the numbers of payouts determined during the bonus games. When the bonus game process has been completed, the main CPU 71 adds the value stored in the number-of-payouts storage area for bonus to the value stored in the number-of-credits storage area provided in the RAM 73, in the payout process of step S24 described with reference to
Next, the main CPU 71 subtracts one from the value stored in the number-of-bonus-games storage area (step S202). Next, the main CPU 71 determines whether or not the value stored in the number-of-bonus-games storage area is zero (step S203). When the main CPU 71 determines that the value stored in the number-of-bonus-games storage area is not zero (step S203: NO), the main CPU 71 shifts the process to step S193. On the other hand, when the main CPU 71 determines that the value stored in the number-of-bonus-games storage area is zero (step S203: YES), the main CPU 71 completes the bonus game process. When the bonus game process has been completed, the process is shifted to the process of step S21 described with reference to
<Insurance Selection Process>
Next, with reference to
First, the main CPU 71 determines whether or not the insurance-effective flag is turned on (step S221). When the main CPU 71 determines that the insurance-effective flag is not turned on (step S221: NO), the main CPU 71 displays an insurance-ineffective image (step S222). The main CPU 71 transmits a command to display the insurance-ineffective image to the graphic board 130. Based on the command, the graphic board 130 generates the insurance-ineffective image and displays the image to the lower image display panel 141. As the insurance-ineffective image, for example, an image showing “INSURANCE BET $1.00 TOUCH TO BET” is displayed. This image is an image for prompting the player to select whether or not to make the insurance effective, and notifying the player of the amount required for making the insurance effective. The player can input a command to make the insurance effective by touching a predetermined place on the touch panel 114.
Subsequently, the main CPU 71 determines whether or not an insurance-effective command input has been entered (step S223). When the main CPU 71 determines that the insurance-effective command input has not been entered (step S223: NO), the main CPU 71 shifts the process to step S221 with the insurance-effective flag turned off. On the other hand, when the main CPU 71 determines that the insurance-effective command input has been entered (step S223: YES), the main CPU 71 turns the insurance-effective flag on (step S224).
Next, the main CPU 71 subtracts the insurance-purchase amount from the value stored in the number-of-credits storage area (step S225). In the present embodiment, an amount corresponding to, for example, one dollar is subtracted from the value stored in the number-of-credits storage area. After step S225 or when determining in step S221 that the insurance-effective flag is turned on (step S221: YES), the main CPU 71 displays the insurance-effective image (step S226). As the insurance-effective image, for example, an image showing “INSURANCE CONTINUED WIN 200 CREDIT” is displayed. This image is an image informing the player that the insurance is effective, and that the value of “200” is to be added to the value stored in the number-of-credits storage area when the insurance condition is satisfied. After the process has been performed, the process is shifted to step S221.
<Common Game Running Process>
Next, the following describes the common game running process with reference to
First, the main CPU 71 changes the game setting of the slot machine 10 to a game setting for a common game, based on the common game program and the common game information stored in the RAM 73 (step A41). For example, the symbol columns are changed from the symbol columns for the individual game (see
Next, the main CPU 71 performs the at-one-game-end initialization process (step A42) as is the case of the step S12 described with reference to
Next, the main CPU 71 performs the symbol display control process described with reference to
On the other hand, when the main CPU 71 determines that a winning combination is achieved (step A46: YES), the main CPU 71 performs a payout process based on the winning combination (step A47), and transmits to the external controller 200 a winning signal indicating the number of light emitting portions 403 whose respective states are to be changed (step A48). The process then goes to step A49.
In step A49, the main CPU 71 determines whether or not the game result information of the common game is received from the external controller 200. If the main CPU 71 determines that no game result information is received (step A49:NO), the process returns to step A42.
On the other hand, when the main CPU 71 determines that the game result information is received (step A49:YES), the main CPU 71 awards a payout based on the game result information (step A50). Next, the main CPU 71 changes the game setting to the individual game setting based on the individual game information stored in the RAM 73 (step A51), and ends this process routine.
<Center-Side Process>
Next, the following describes a center-side process with reference to
First, the main CPU 241 determines whether or not a game information requesting command is received from any of the slot machines 10 (step B11). When the main CPU 241 determines that the game information requesting command is received (step B11: YES), the main CPU 241 starts the thread of a file transmission process (see
On the other hand, when the main CPU 241 determines that no game information requesting command is received (step B11: NO), the main CPU 241 determines whether or not a trigger value is received from any slot machine 10 (step B13). When the main CPU 241 determines that no trigger value is received (step B13: NO), the process goes to the step B17.
On the other hand, when the main CPU 241 determines that a trigger value is received (step B13: YES), the main CPU 241 adds the trigger value to the total accumulated value or the individual accumulated value stored in the RAM 243 (step B14). Next, the main CPU 241 determines whether or not the total accumulated value or the individual accumulated value stored in the RAM 243 has reached the threshold stored in RAM 243 (step B15). When the main CPU 241 determines that the accumulated value has not reached the threshold (step B15: NO), the process returns to step B11.
On the other hand, when the main CPU 241 determines that the accumulated value has reached the threshold (step B15: YES), the main CPU 241 transmits the common game start signal to the plurality of slot machines 10 (step B16). The process then returns to step B11.
In step B17, the main CPU 241 determines whether or not a winning signal is received. When the main CPU 241 determines that no winning signal is received (step B17: NO), the process goes to step B22.
On the other hand, when the main CPU 241 determines that the winning signal is received (step B17: YES), the main CPU 241 changes, based on the winning signal, the status of the light emitting portions 403 in the path 401 corresponding to the slot machine 10 having transmitted the winning signal, towards the common game payout display unit 400 (step B18). Next, the main CPU 241 determines whether or not the status of the plurality of light emitting portions 403 of any path 401 has changed all the way up to the common game payout display unit 400 so as to determine whether any slot machine 10 has won a payout of the common game (step B19). When the main CPU 241 determines that no slot machine 10 has won the payout of the common game (step B19: NO), the process returns to step B11.
On the other hand, when the main CPU 241 determines that the payout of the common game has been won by a slot machine 10 (step B19: YES), the main CPU 241 performs a payout awarding process for awarding the payout of common game, and outputs the game result information of the common game (step B20). Note that the game result information of the common game transmitted to the slot machine 10 having won the payout includes a payout award signal indicating the payout amount of the common game. Next, the main CPU 241 subtracts a predetermined amount from the total accumulated value or the individual accumulated value, according to the amount of payout awarded in the common game, and stores the resulting value in the RAM 243 (step B21). The process then returns to step B11. Note that, in step B21, the threshold of the total accumulated value or the individual accumulated value stored in the RAM 243 which value serves as the common game starting condition may be variable.
In step B22, the main CPU 241 determines whether or not the resulting signature is received from the slot machine 10. When the main CPU 241 determines that no resulting signature is received (step B22: NO), the process returns to step B11.
On the other hand, when the main CPU 241 determines that the resulting signature is received (step B22: YES), the main CPU 241 compares the signature extracted from the common game information stored in the RAM 243 with the resulting signature, to check if there is any fraud such as tampering of data in the files during the communication between the slot machine 10 and the external controller 200 (step B23). Next, the main CPU 241 transmits, to the slot machine 10 having transmitted the resulting signature, the signature determination result which is the result of determining the presence of any fraud (step B24). The process then returns to step B11.
<File Transmission Process>
Next, the following describes the file transmission process with reference to
First, the main CPU 241 determines whether the identification information contained in the game information requesting command received from the slot machine 10 matches with the identification information corresponding to the common game information stored in the RAM 243 (step B31). When the main CPU 241 determines that the two pieces of identification information match with each other (step B31: YES), the main CPU 241 transmits to the slot machine 10 update command information indicating no transmission of common game information is to be performed (step B32).
On the other hand, when the main CPU 241 determines that the two pieces of identification information match with each other (step B31: NO), the main CPU 241 transmits to the slot machine 10 the update command information indicating that transmission of the common game information is to be performed (step B33). Next, the main CPU 241 transmits the file size of the common game information file stored in the memory card 253 to the slot machine 10 (step B34).
Next, the main CPU 241 reads the common game information file stored in the memory card 253 in units of 50 KB, and transmits the file to the slot machine 10 (step B35). Note that in step B35, the main CPU 241 also transmits the identification information corresponding to the common game information to the slot machine 10.
Next, the main CPU 241 determines whether transmission of all the data of the common game information file stored in the memory card 253 to the slot machine 10 is completed (step B36). When the main CPU 241 determines that transmission of all the data is not completed (step B36: NO), the process returns to step B35. On the other hand, when the main CPU 241 determines that transmission of all the data is completed (step B36: YES), the main CPU 241 transmits, to the slot machine 10, a transmission end signal indicating that transmission of all the data of the common game information file is completed (step B37), and the process routine ends thereafter.
As described, the common game information for use in the common game which is run in the plurality of slot machines 10 is received from the external controller 200, when the slot machine 10 is booted. Therefore, changing the common game information managed by the game information management device of the external controller 200 will change the common game information in the slot machines 10 connected to and in communication with the external controller 200. This reduces the work required for changing the common game information for use in the common game. Further, since the common game information is received from the external controller 200 when the slot machine 10 is booted, the slot machine 10 is able to run the common game based on the common game information immediately after reception of a common game starting command from the external controller 200.
Further, as described above, the external controller 200 transmits the common game information to the slot machine 10, only when the common game information stored in the terminal-side game information storage device of the slot machine 10 and the common game information stored in the game information management device of the external controller 200 do not match with each other. This reduces the work for changing the common game information.
One embodiment of the present invention is thus described hereinabove. The present invention however is not limited to the above embodiment. For example, the following embodiment of the present invention is also possible. The following describes a gaming machine of another embodiment of the present invention.
A gaming machine of the other embodiment is adapted so that the common game information is received from the external controller 200 and the content of the common game is changed, when no player plays a game in a slot machine 10 for a predetermined period.
[Terminal-Side Process]
First, the following describes a terminal-side process of the other embodiment, with reference to
First, the main CPU 71 detects boot of a slot machine 10 (step A61). Next, the authenticated game system program, a game program (the individual game information), and the common game program are read out from the GPCF 57 and the GSCF 58 via the gaming board 50, and are written into the RAM 73 (step A62).
Next, the main CPU 71 performs a terminal-side game information transmission/reception process described with reference to
Next, the main CPU 71 determines whether or not the common game update information containing the identification information of the common game information subject to the change is received from the external controller 200 (step A64). When the main CPU 71 determines that the common game update information is not received (step A64: NO), the process goes to step A71.
On the other hand, when the main CPU 71 determines that the common game update information is received (step A64: YES), the main CPU 71 determines if no game has been performed in the slot machine 10 for a predetermined period (step A65). When the main CPU 71 determines that a game has been performed by a player before the elapse of the predetermined period (step A65: NO), the process goes to step A71.
On the other hand, when the main CPU 71 determines that no game has been performed for the predetermined period (step A65: YES), the main CPU 71 transmits a terminal-vacancy signal indicating that the no game has been played by a player (step A66). Next, the main CPU 71 determines whether the identification information in the common game update information and the identification information stored in the RAM 73 match with each other, so as to determine whether the common game information has been already updated (obtained) (step A67). When the main CPU 71 determines that the common game information has been updated (step A67:NO), the process goes to step A69.
On the other hand, when the main CPU 71 determines that the common game information has not been updated (step A67: YES), the main CPU 71 performs the terminal-side game information transmission/reception process which is described with reference to
In step A69, the main CPU 71 determines whether or not a common game update command is received from the external controller 200. When the main CPU 71 determines that no common game update command has been received (step A69: NO), the process returns to step A64.
On the other hand, when the main CPU 71 determines that the common game update command has been received (step A69: YES), the main CPU 71 changes the game setting so that the common game is run by using the second common game information after the step A69 (step A70). The process then returns to step A64.
In step A71, the main CPU 71 performs the individual game running process described with reference to
[Center-Side Process]
First, the following describes a center-side process of the other embodiment with reference to
Step B11 to step B24 are the same as those of the center-side process described with reference to
In step B22, when the main CPU 241 determines that no resulting signature is received (step B22: NO), the main CPU 241 determines whether or not a common game update command is received (step B41). The common game update command is a command that occurs, for example, when the memory card 253 inserted into the card slot 253S is changed, or use of different common game information in the memory card 253 for the common game is instructed by an operation from the outside.
When the main CPU 241 determines that the common game update command is received (step B41: YES), the main CPU 241 transmits the common game update information to the slot machine 10 (step B42). The process then returns to step B11.
On the other hand, when the main CPU 241 determines that no common game update command has been received (step B42: NO), the main CPU 241 determines whether transmission of the common game information is completed in relation to all of the slot machines 10 connected to and in communication with the external controller 200 (step B43). It is possible to add to the condition in this process the reception of terminal vacancy signal from all the slot machines 10 connected to and in communication with the external controller 200. In other words, the main CPU 241 may determine whether transmission of the common game information is completed in relation to all the slot machines 10 connected to and in communication with the external controller 200, and whether a terminal vacancy signal is received from all the slot machines 10.
When the main CPU 241 determines that transmission of the common game information to all the slot machine 10 is not completed (step B43: NO), the process returns to step B11.
On the other hand, when the main CPU 241 determines that the transmission of the common game information to all the slot machines 10 has been completed, the main CPU 241 transmits the common game update command to the slot machines 10 (step B44). The process then returns to step B11.
As described above, in the other embodiment, the common game information is received from the external controller 200 and the content of the common game is changed when no game has been played by the player. The timing for transmitting the common game information is differentiated among the plurality of slot machines 10 connected to and in communication with the external controller 200. This prevents the plurality of slot machines 10 from accessing the external controller 200 all at once, and shortens the period for transmitting the common game information to each slot machine 10.
Next, the following describes an example of the present invention with reference to
