1. Field of the Invention
The present invention relates to a slot machine and a playing method thereof.
2. Description of Related Art
In a known slot machine, when a player inserts a game medium such as coin or bill into an insertion slot of the slot machine and presses a spin button, symbols are scrolled in a display mounted on a front of a cabinet and then stopped automatically.
In such slot machine, as disclosed in U.S. Pat. No. 6,604,999B2 or U.S. Patent No. 2002065124A1, for example, when the symbols stopped on a payline form a predetermined combination, a predetermined number of game media are paid out. Further, a predetermined number of game media are paid out according to the number of symbols referred to as scatter symbols displayed on the display, irrespective of the payline.
In the known slot machine, when a predetermined condition is fulfilled, a feature game is run which puts a player in a more advantageous stage by offering a chance of winning a higher payout than a base game where the symbols are scrolled and stopped after a game medium is inserted. However, when a bet is required to play the feature game, the required bet amount is constant, i.e., not changed. Due to this, a player has a difficulty in recognizing whether s/he is in a better or worse position compared to another player.
An object of the invention is to provide a slot machine having an entertainment characteristic which is not brought about by the above mentioned prior art, and a playing method thereof.
Another object of the invention is to provide a slot machine enabling a player to easily recognize gap from another player in terms of a required bet amount on a feature game, and a playing method thereof.

According to the above structure, the special game is run when a predetermined number or more of specific scatter symbols, among the scatter symbols rearranged in the arrangement area of the matrix, are rearranged. Further, a required bet amount of the special game is set according to the number of the specific scatter symbols rearranged. Hence, for example, the more the number of specific scatter symbols, the less the required bet amount of the special game. This removes the unfair feeling between a player who has more specific symbols rearranged and a player who has fewer specific symbols rearranged. Thus, a player is able to feel whether s/he is in a better/worse position compared to another player, in terms of bet amount. In addition to the gaming characteristic that the special game is run while the player is enjoying the base game, it is possible to provide a player with the gaming characteristic that the required bet amount of the special game run is changed.
The following describes an embodiment of a slot machine and a playing method thereof according to the present invention.
As shown in
The “arrangement” in this specification means a state where the scatter symbols 180 including the trigger symbols 180J can be visually observed by a player. In short, the wording means the scatter symbols 180 displayed in the symbol arrangement areas 151 to 155. Arranging the scatter symbols 180 again after dismissing them is referred to as “rearranging”. The symbol arrangement areas 151 to 155 will be described later.
Each of the “scatter symbols” is a symbol whose arrangement could result in a winning irrespective of a pay line L. Appearance of a predetermined number (for example, three) of scatter symbols in the symbol arrangement areas 151 to 155 gives an advantage to a player. For example, the advantages includes: a state where coins corresponding to the scatter symbols 180 arranged are paid out, a state where the number of coins to be paid out is added to a credit, a state where a feature game is started.
Each of the “trigger symbols 180” is a symbol that is included in the scatter symbols 180. Appearance of a predetermined number (for example, three) or more of trigger symbols in the symbol arrangement areas 151 to 155 runs a feature game. In the present embodiment, a symbol of “BONUS” is used as the trigger symbol 180J. However, the invention is not limited thereto.
A “basic game” in this specification is a game in which scatter symbols 180 are rearranged in the symbol arrangement areas 151 to 155 and a payout is awarded when a winning is formed according to a relation of the base symbols 180 rearranged. The basic game is run under base state. In the present embodiment, the basic game has a required bet amount of “one credit.” That is, when a player inserts one coin corresponding to one credit in the slot machine 1, the player can play the basic game.
The “feature game” is a so-called bonus game in which the higher payout than the basic game is awarded to a player and a superiority degree of the payout to a player is higher than the basic game. Further, the feature game is run when a predetermined number (for example, three) or more of the trigger symbols 180J, among the scatter symbols 180 arranged in the symbol arrangement areas 151 to 155, are rearranged. Moreover, in the present embodiment, the feature game is divided into two types, i.e., a basic feature game and a special feature game. The shifting to the basic feature game from the basic game is referred to as basic feature IN and the shifting to the special feature game from the basic game is referred to as special feature IN. The basic feature IN and the special feature IN are collectively referred to as feature IN.
The “basic feature game” is a feature game that is run when three or four trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155 in a basic game. The basic feature game that is run when the three trigger symbols 180J are arranged has a required bet amount of “three credits.” The basic feature game that is run when the four trigger symbols 180J are arranged has a required bet amount of “two credits.” As described above, the shifting to the basic feature game from the basic game is referred to as basic feature IN.
The “special feature game” is a feature game that is run when five trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155 or three or more trigger symbols 180J are successively rearranged in a row direction, in a basic game. The special feature game is a free game and has a required bet amount of “0 credit.” Accordingly, the special feature game is a game that is most advantageous to a player. As described above, the shifting to the special feature game from the basic game is referred to as special feature IN.
The “required bet amount” is a minimum bet amount that is necessary for a player to play a game in the “basic game” and the “feature game.”
For example, in
In addition, when there are two symbols of “BONUS”, which are the trigger symbols 180J arranged in the symbol arrangement areas 151 to 155 (refer to 4B(b)), a basic game is run without shifting to the feature IN. In this case, the required bet amount remains one credit.
When the three trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155 (refer to 4B(c)), a basic feature IN is formed, so that a basic feature game is run. In this case, since the basic feature IN is formed under state that the three trigger symbols 180J are arranged, the required bet amount is set to “three credits.” For example, when the basic feature IN is formed under state the four trigger symbols 180J are arranged, the required bet amount is set to “two credits.”
In addition, when the five trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155 (refer to 4B(d)), a special feature IN is formed, so that a special feature game is run. This is a free game, and the required bet amount is set to “zero credit.”
As shown in
(Central Display 4B)
The central display 4B serving as a display unit has the symbol arrangement areas 151 to 155 and a required bet amount display area 160, as shown in
The symbol arrange areas 151 to 155 are areas in which the scatter symbols 180 are arranged in the central display 4B and divided into an upper stage 150a, a middle stage 150b and a lower stage 150c, respectively. The required bet amount display area 160 is an area in which required bet amounts in the basic and feature games are displayed. The area is displayed in a right top of the central display 4B.
In the present embodiment, the “row” means a horizontal symbol column of the symbol arrangement areas 151 to 155 having a matrix, and the “column” means a vertical symbol column of the symbol arrangement areas 151 to 155 having a matrix. The “column direction” is a scroll direction of the scatter symbols 180 and the “row direction” is a direction perpendicular to the scroll direction of the scatter symbols 180. In short, the symbol arrangement areas 151 to 155 having a matrix of 3 rows/5 columns.
The central display 4B may have a mechanical structure adopting a reel device which rotates a reel to arrange the scatter symbols 180. Alternatively, the central display 4B may have an electric structure in which a video reel is displayed as an image, and the symbols on the video reel are arranged in the form of an image. Further, the central display 4B may adopt a combination of the mechanical structure (reel) and the electrical structure (video reel). Examples of the electrical structure include a liquid crystal display device, a CRT (cathode-ray tube), a plasma display device, or the like. The number of the symbol arrangement areas 151 to 155 is not particularly limited. A specific display state of the central display 4B will be described below.
(Game Controller 100)
The game controller 100 is structured to execute a playing method including: a first process of rearranging scatter symbols 180 in symbol arrangement areas 151 to 155; a second process of awarding a payout according to the number of the scatter symbols 180 rearranged; a third process of running a feature game when a predetermined number (for example, 3) or more of trigger symbols 180J, among the rearranged scatter symbols 180, are rearranged; and a fourth process of setting a required bet amount of the feature game run, according to the number of the trigger symbols 180J rearranged.
In addition, the game controller 100 is structured to execute a fifth process of running a special feature game in which the required bet amount is set to zero, when a specified number (for example, five) or more of the trigger symbols 180J are rearranged, the specified number being larger than the predetermined number (for example, 3).
In addition, the game controller 100 is structured to execute a sixth process of running a special feature game in which a required bet amount is set to zero, when the predetermined number (for example, three) or more of the trigger symbols 180J are arranged while being successively rearranged in a row direction of one row in the symbol arrangement areas 151 to 155.
Further, the game controller 100 is structured to execute a seventh process of ending the feature game run, when a reset button 310 of the slot machine 1 is pressed. In other words, the terminal controller 100 has first to seventh processing units.
As shown in
The game starting unit 110 has a function of outputting a game start signal, in response to an operation by the player. The game start signal output is then input to a later-detailed game running unit 103.
The BET unit 111 has functions of receiving a bet entered through an operation by the player, and outputting a BET signal. The BET signal output is input to the later-detailed game running unit 103.
The count unit 123 starts or stops timing, under control of a later-detailed game running unit 103.
The reset unit 124 outputs a reset button pressed signal to a later-detailed game running unit 103 when a later-detailed reset button 310 is pressed by a player.
When an ID card 300 is inserted into a later-detailed card reader 15 of the slot machine 1, the ID data receiving unit 125 reads out and receives ID data from the ID card 300. In addition, the ID card receiving unit also has a function of detecting that the ID card 300 is removed from the card reader 15 and the ID data is read out (discharged). When the ID card 300 is inserted into the card reader 15, the ID data receiving unit 125 outputs an input signal to an ID data comparison unit 121. When the ID card 300 is removed from the card reader 15, the ID data receiving unit 125 outputs a discharge signal to the ID data comparison unit 121.
The “ID card 300” is possessed by each player and is a storage medium that stores the ID data allotted to each player, data about game history played by a player and the like. In this embodiment, a game can be run only when the ID card 300 is inserted into the card reader 15 and the ID data is received. In this embodiment, the “ID data” is identification data that is allotted to each of players so as to identify a player.
In addition, the game controller 100 includes an ID data storage unit 122 and an ID data comparison unit 121.
The ID data storage unit 122 stores ID data that is stored in the ID card 300 inserted into the ID data receiving unit 125. In short, the ID data storage unit 122 stores the ID data of a player who plays a game with the slot machine 1.
The ID data comparison unit 121 stores the ID data newly inputted from the ID data receiving unit 125 in the ID data storage unit 122, based on an ID data input signal from the ID data receiving unit 125. In addition, the ID data comparison unit 121 compares the newly inputted ID data with the original ID data stored in the ID data storage unit 122. As a result, when both ID data are not identical to each other, the ID data comparison unit outputs an ID data-inappropriate signal to a later-detailed game running unit 103. In response to the ID data discharge signal received from the ID data receiving unit 125, the ID data comparison unit 121 deletes the ID data stored in the ID data storage unit 122.
The game controller 100 includes: a symbol storage unit 108, a required bet amount storage unit 120, a display storage unit 107, a display control unit 102 and a game running unit 103.
The symbol storage unit 108 stores the scatter symbols 180. The required bet amount storage unit 120 stores required bet amounts in the basic game, the basic feature game and the special feature game.
The display storage unit 107 stores, as scatter symbols 180 to be displayed, the scatter symbols 180 in the symbol storage unit 108. In addition, the display storage unit 107 stores, as required bet amounts to be displayed, the required bet amounts in the bet amount storage unit 120.
Further, the display control unit 102 reads out scatter symbols 180 to be displayed from the display storage unit 107 and displays the scatter symbols 180 in the symbol arrangement areas 151 to 155, under control of the game running unit 103. In addition, under control of the game running unit 103, the display control unit 102 reads out the required bet amount to be displayed from the display storage unit 107 and displays the required bet amount in the required bet amount display area 160.
The game running unit 103 runs a basic game, triggered by the game start signal from the game starting unit 110. The basic game is a game in which scatter symbols 180 are rearranged in the symbol arrangement areas 151 to 155 of the central display 4B. Further, when a predetermined number or more trigger symbols 180J, among the scatter symbols 180 arranged in the symbol arrangement areas 151 to 155, are arranged, the game running unit 103 runs a feature game.
Moreover, the game running unit 103 sets a required bet amount in a basic game, according to the number of the trigger symbols 180J arranged in the symbol arrangement areas 151 to 155, the arranged location and the like. To be more specific, when three trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155, the game running unit 103 runs a basic feature game in which the required bet amount is set to “3 credits.” When four trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155, the game running unit 103 runs a basic feature game in which the required bet amount is set to “2 credits.” Further, when five or more trigger symbols 180J are arranged, the game running unit 103 runs a special feature game in which the required bet amount is set to “0 credit.” Moreover, when three or more trigger symbols 180J are arranged while being successively arranged in a row direction, the game running unit runs a special feature game in which the required bet amount is set to “zero credit.” The game running unit 103 causes the display control unit 102 to display the required bet amount set on the bet amount display area 160.
In addition, in response to the ID data-inappropriate signal received from the ID data comparison unit 121 during the feature game, the game running unit 103 ends the feature game that is being run.
In response to the reset button pressed signal received from the reset unit 124 during the feature game, the game running unit 103 ends the feature game that is being run.
When running the feature game, the game running unit 103 causes the count unit 123 to start timing. After a predetermined period of time (for example, 10 minutes) for which the count unit 123 times, the game running unit ends the feature game that is being run. When a game start signal is received from the game starting unit 110 in a predetermined period of time after the count unit 123 has started timing, the game running unit causes the count unit 123 to stop timing.
The game controller 100 includes a payout determining unit 105 and a payout award unit 104.
The payout determining unit 105, under control of the game running unit 103, determines whether to award payouts of a basic game and a feature game on the basis of a relation of the scatter symbols 180 rearranged in the symbol arrangement areas 151 to 155. When it is determined that a combination is formed, the payout determining unit 105 determines a payout amount and outputs a signal to the payout award unit 104.
The payout award unit 104 awards the payouts of the basic game and the feature game, based on the determination of the payout determining unit 105.
Meanwhile, each block of the game controller 100 may be realized with hardware or with software as needed.
(Operation of Game Controller 100)
The following describes an operation of the game controller 100 in the above structure. First, the BET unit 111 receives a BET entered through an operation by a player. Further, a game start signal is output from the game starting unit 110 in response to the player's operation, and a basic game is run by the game running unit 103. When the basic game is run, the display control unit 102, under control of the game running unit 103, displays scatter symbols 180 in the symbol arrangement areas 151 to 155. Like this, the game controller 100 performs the first process of rearranging the scatter symbols 180 in the symbol arrangement areas 151 to 155.
Further, the payout determining unit 105 determines whether the basic game has resulted in a winning, based on a relation among the scatter symbols 180 rearranged in the symbol arrangement areas 151 to 155. When it is determined that the basic game has resulted in a winning, the payout determining unit 105 determines a payout amount. The payout of the basic game thus determined is awarded by the payout award unit 104. Like this, the game controller 100 performs the second process of awarding a payout according to the number of scatter symbols 180 rearranged.
Further, in the basic game, when a predetermined number (for example, three) or more of the trigger symbols 180J, among the scatter symbols 180 arranged in the symbol arrangement areas 151 to 155, are arranged, the game running unit runs a feature game. Like this, the game controller 100 performs the third process of running a feature game when a predetermined number (for example, three) or more of trigger symbols 180J, among the rearranged scatter symbols 180, are rearranged.
Moreover, in the basic game, the game running unit 103 sets a required bet amount according to the number of scatter symbols 180 arranged in the symbol arrangement areas 151 to 155, the arranged location and the like. In addition, at this time, the display control unit 102 displays the required bet amount set on the required bet amount display area 160. Like this, the game controller 100 performs the fourth process of setting a required bet amount of the feature game run, according to the number of the trigger symbols 180J rearranged.
Meantime, when the game running unit 103 sets a required bet amount, if five trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155, a special feature game is run in which the required bet amount is set to “0 credit.” Like this, the game controller 100 performs the fifth process of running a special feature game in which the required bet amount is set to 0, when a specified number (for example, 5) or more of the trigger symbols 180J are rearranged, the specified number being larger than the predetermined number (for example, 3).
Further, when a required bet amount is set, if the three or more trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155 while being successively rearranged in a row direction, the game running unit 103 runs a special feature game in which a required bet amount is set to “0 credit.” Like this, the game controller 100 performs the sixth process of running a special feature game in which a required bet amount is set to 0, when the predetermined number (for example, three) or more of the trigger symbols 180J are arranged while being successively rearranged in a row direction of one row in the symbol arrangement areas 151 to 155.
In addition, when a player presses a later-detailed reset button 310 while the feature game is being run, the reset unit 124 outputs a reset button pressed signal to the game running unit 103. Afterwards, the game running unit 103 having received the reset button pressed signal ends the feature game that is being run. Like this, the game controller 100 performs the seventh process of ending the feature game run, when a reset button 310 of the slot machine 1 is pressed.
As is obvious from the above operations, the slot machine 1 realizes a playing method including the steps of: rearranging scatter symbols 180 in symbol arrangement areas 151 to 155; awarding a payout according to the number of scatter symbols 180 rearranged; running a feature game, when a predetermined number or more of trigger symbols 180J, among the rearranged scatter symbols 180, are rearranged; and setting a required bet amount of the feature game run, according to the number of the trigger symbols 180J rearranged.
According to the above playing method, the feature game is run when a predetermined number or more of trigger symbols 180J, among the scatter symbols 180 rearranged in the symbol arrangement areas 151 to 155 of the matrix, are rearranged. Further, a required bet amount of the feature game is set according to the number of the trigger symbols 180J rearranged. Hence, for example, the more the number of trigger symbols 180J, the less the required bet amount of the feature game. This removes the unfair reeling between a player who has more trigger symbols 180J rearranged and a player who has fewer trigger symbols 180J rearranged. Thus, a player is able to feel whether s/he is in a better/worse position compared to another player, in terms of bet amount. In addition to the gaming characteristic that the feature game is run while the player is enjoying the basic game, it is possible to provide a player with the gaming characteristic that the required bet amount of the feature game run is changed.
In addition, the slot machine 1 realizes the playing method including the step of running the special feature game in which the required bet amount is set to 0, when a specified number or more of the trigger symbols 180J are rearranged, the specified number being larger than the predetermined number.
According to the playing method, when a specified number or more of the trigger symbols 180J are rearranged, the specified number being larger than the predetermined number, a special feature game is run in which the required bet amount is set to 0. Hence, it is possible to enable a player to aim at a state in which the more trigger symbols 180J are arranged, so that the gaming characteristic is more improved.
Further, the slot machine 1 realizes the playing method including the step of running the special feature game in which the required bet amount is set to 0, when the predetermined number or more of the trigger symbols 180J are rearranged while being successively rearranged in a row direction of one row in the symbol arrangement areas 151 to 155.
According to the playing method, when the predetermined number or more of the trigger symbols 180J are rearranged while being successively rearranged in a row direction of one row, the special feature game is run in which the required bet amount is set to 0. Hence, it is possible to enable a player to aim at a state in which the trigger symbols 180J are successively arranged in a row direction, so that the gaming characteristic is more improved.
Moreover, the slot machine 1 realizes the playing method including the step of ending the feature game run, when a later-detailed reset button 310 of the slot machine 1 is pressed.
The above playing method enables a player to press the reset button 310, thereby ending the feature game run. Accordingly, the player is enabled to select whether to play the feature game based on his/her determination. This enables the player to select a game more freely.
(Display State of Central Display 4B)
The following details an exemplary display state of the central display 4B during the operations of the slot machine 1 and the playing method thereof. Note that the following example deals with a case where the central display 4B adopts a video reel and arranges the scatter symbols 180 on a video reel in the form of an image, as illustrated in

In the present embodiment, when a predetermined number (for example, three) or more of the scatter symbols 180 having a same type are displayed in the symbol matrix, a process of paying out coins and the like is performed. However, for example, a process may be adopted in which payline L crossing the middle stages 150b of the respective symbol arrangement areas 151 to 155 are provided and coins and the like are paid out when the scatter symbols 180 stopped on the paylines L constitute a predetermined combination.
Further, the required bet amount display area 160 is displayed in the right top of the central display 4B. The area displays a required bet amount of a game that is currently played by a player. Thus, it is possible to enable a player to play a game while seeing the required bet amount of a game that is played by the player.

As shown in
Of the symbols in the symbol columns, the symbol arrangement areas 151 to 155 each displays (arranges) three successive scatter symbols 180. The symbols arranged in the upper stage 150a, the middle stage 150b, and the lower stage 150c form a symbol matrix having five columns and three rows. When a bet button and a start button are then pressed to start a game, scatter symbols 180 constituting the symbol matrix start to scroll. This scrolling of the symbols stops (rearrangement) after a predetermined period from the beginning of the scrolling.
In addition, when a predetermined number or more scatter symbols 180 having a same type are displayed in the symbol arrangement areas 151 to 155, an advantageous state is given to a player. For example, the advantageous state includes: a state where coins corresponding to the scatter symbols are paid out, a state where the number of coins to be paid out is added to a credit, a state where a bonus game is started and the like.
To be more specific, when three or more scatter symbols 180 having a same type are rearranged in the symbol arrangement areas 151 to 155, twenty coins (game media) are paid out for one bet. In addition, when a predetermined number (for example, three) or more of the trigger symbols 180J are rearranged, a feature game trigger is made, so that the gaming state is shifted to a feature game from a basic game.
As described above, the feature game is a gaming state that is more advantageous to a player than the basic game. Meantime, another feature game may be adopted together as long as it is advantageous to a player, i.e., it is more advantageous than the basic game. For example, another feature game may include: a state where more game media can be obtained that in the basic game, a state where the game media can be obtained in a higher probability than the basic game, a state where less game media are consumed that in the basic game, and the like.

(Electrical Structure of Slot Machine 1)
The gaming board 50 is provided with a CPU (Central Processing Unit) 51, a ROM 55, a boot ROM 52, a card slot 53S corresponding to a memory card 53, and an IC socket 54S corresponding to a GAL (Generic Array Logic) 54. The CPU 51, the ROM 55, and the boot ROM 52 are connected to one another through an internal bus.
The memory card 53 stores therein a game program and a game system program. The game program contains a stop symbol determining program. The symbol determining program is for determining scatter symbols 180 (code numbers corresponding to the symbols) to be stopped in the symbol arrangement areas 151 to 155. This stop symbol determining program contains sets of symbol weighting data respectively corresponding to various payout rates (e.g., 80%, 84%, 88%). Each set of the symbol weighting data indicates, for each of the symbol arrangement areas 151 to 155, a corresponding relation between a code number of each scatter symbol 180 and at least one random numerical value within a predetermined range of 0 to 256, for example.
The payout rate is determined based on payout rate setting data output from the GAL 54. Based on a set of the symbol weighting data corresponding to the payout rate determined, a symbol to be stopped is determined.
The memory card 53 stores therein various types of data for use in the game programs and the game system programs. For example, the data indicating a relation between a scatter symbol 180 to be displayed on the symbol arrangement areas 151 to 155 of
The card slot 53S is structured so as to allow the memory card 53 to be attached/detached to/from the card slot 53S. This card slot 53S is connected to the motherboard 40 through an IDE bus. Thus, the type and content of a game run by a slot machine 1 can be modified by detaching the memory card 53 from the card slot 53S, writing a different game program and a different game system program into the memory card 53, and then inserting the memory card 53 back into the card slot 53S.
Each of the game programs includes a program related to the progress of the game and/or a program for causing a transition to a feature game. Each of the game programs includes image data and audio data output during the game.
The GAL 54 has input and output ports. When the GAL 54 receives data via the input port, it outputs data corresponding to the input data from its output port. This data from the output port is the payout rate setting data described above.
IC socket 54S is structured so as to allow the GAL 54 to be attached/detached to/from the IC socket 54S. The IC socket 54S is connected to the motherboard 40, via a PCI bus. Thus, the payout rate setting data to be output from GAL 54 can be modified by: detaching the GAL 54 from the IC socket 54S, overwriting the program stored in the GAL 54, and attaching the GAL 54 back to the IC socket 54S.
The CPU 51, the ROM 55 and the boot ROM 52 connected through an internal bus are connected to the motherboard 40 through the PCI bus. The PCI bus communicates signals between the motherboard 40 and the gaming board 50 and supplies power from the motherboard 40 to the gaming board 50. The ROM 55 stores country identification information and an authentication program. The boot ROM 52 stores a preliminary authentication program and a program (boot code) for enabling the CPU 51 to run the preliminary authentication program.
The authentication program is a program (falsification check program) for authenticating the game program and the game system program. The authentication program is a program for confirming and verifying that the game program and the game system program are not falsified. In other words, the authentication program is described in accordance with a procedure for authenticating the game program and the game system program. The preliminary authentication program is a program for authenticating the authentication program. The preliminary authentication program is described in accordance with a procedure for verifying that the authentication program to be authenticated is not falsified.

(Process Routine of Slot Machine 1: Boot Process Routine)
The following describes a boot process routine that is executed in the slot machine 1. Upon powering on the slot machine 1, a boot process routine of
First, turning on the power switch of (powering on) the power unit 45 boots the motherboard 40 and the gaming board 50. Booting the motherboard 40 and the gaming board 50 starts separate processes in parallel. Specifically, in the gaming board 50, the CPU 51 reads out a preliminary authentication program stored in the boot ROM 52. Then, preliminary authentication is performed according to the read out program so as to confirm and authenticate that no modification is made to the authentication program, before reading them in the motherboard 40 (S1). Meanwhile, the main CPU 41 of the motherboard 40 runs BIOS stored in the ROM 42 to load into the RAM 43 compressed data built in the BIOS (S2). Then, the main CPU 41 runs a procedure of the BIOS according to the data loaded into the RAM 43 so as to diagnose and initialize various peripheral devices (S3).
The main CPU 41, which is connected to the ROM 55of the gaming board 50 via a PCI bus, reads out the authentication program stored in the ROM 55 and stores it in the RAM 43 (S4). During this step, the main CPU 41 derives a checksum through ADDSUM method (a standard check function) which is adopted in a standard BIOS, and store the authentication program into RAM 43 while confirming if the operation of storing is carried out without an error.
Next, the main CPU 41 checks what connects to the IDE bus. Then, the main CPU 41accesses, via the IDE bus, to the memory card 53 inserted into the card slot 53S, and reads out a game program and a game system program from the memory card 53. In this case, the main CPU 41 reads out four bytes of data constituting the game program and the game system program at one time. Next, with the authentication program stored in the RAM 43, the main CPU 41 authenticates the game program and the game system program read out to confirm and prove that the programs are not modified (S5).
When the authentication properly ends, the main CPU 41 writes and stores the authenticated game program and game system program in the RAM 43 (S6).
Next, the main CPU 41 accesses, via the PCI bus, to the GAL 54 attached to the IC socket 54S, and reads out payout rate setting data from the GAL 54. The payout rate setting data read out is then written and stored in the RAM 43 (S7).
Next, the main CPU 41 reads out, via the PCI bus, country identification information stored in the ROM 55 of the gaming board 50. The country identification information read out is then stored in the RAM 43 (S8).
After this, the main CPU 41 performs an initial process of
(Process Routine of Slot Machine 1: Initial Process Routine)
The following describes an initial process routine that is executed in the slot machine 1. When the boot process of
First, the main CPU 41 of the slot machine 1 checks operations of a work memory such as RAM 43 (A1). Then, the main CPU 41 determines if all the check results are normal (A2). When the main CPU 41 determines that the check results contain an error (A2: NO), the main CPU 41 outputs a signal notifying the error (hereinafter, error signal) to the host computer (A3) Further, the main CPU 41 reports the error in the form of illuminating the lamps 30 or the like (A4), and then ends the routine.
On the other hand, when the main CPU 41 determines that the check results are all normal (A2: YES), the main CPU 41 checks operations of various sensors (A5). Then, the main CPU 41 determines if all the check results are normal (A6). When the main CPU 41 determines the check results contain an error (A6: NO), the main CPU 41 executes A3.
On the other hand, when the main CPU 41 determines in A6 that the check results are all normal (A6: YES), the main CPU 41 checks operations of various drive mechanisms (A7). Then, the main CPU 41 determines if all the check results are normal (A8). When the main CPU 41 determines the check results contain an error (A8: NO), the main CPU 241 executes A3.
On the other hand, when the main CPU 41 determines in A8 that the check results are all normal (A8: YES), the main CPU 41 checks operations of various illuminations (A9). Then, the main CPU 41 determines if all the check results are normal (A10). When the main CPU 41 determines the check results contain an error (A10: NO), the main CPU 41 executes A3.
After the checking operations through the steps A1 to A10 for checking operations of various functions, when the main CPU 41 determines in A10 that the check results are all normal (A10: YES), the main CPU 41 outputs a boot signal (A11). Afterwards, the main CPU reads out the game program and the game system program from the RAM 43 (A12), executes a basic game process (A13) and ends this routine.
(Process Routine of Slot Machine 1: Basic Game Running Process Routine)
When the initial process routine of
As shown in
On the other hand, when a coin is bet (B1: YES), the credit value stored in the RAM 43 is reduced according to the number of coins bet (B2). When the number of coins bet surpasses the credit value stored in the RAM 43, the process goes to B3 without the reduction of the credit value. When the number of coins bet exceeds the maximum number of coins bettable in one game (50 pieces in this embodiment), the process goes to a later-detailed step B3 without the reduction of the credit value.
Then, the main CPU determines whether the spin button is ON (pressed) or not (B3). When the spin button is not pressed (B3: NO), the process returns to B1. On the other hand, when the spin button is not ON (pressed) (for example, the spin button 23 is not pressed but a command to end the game is inputted), the reduction of the credit value in B2 is canceled.
On the other hand, when the spin button is pressed (B3: YES), a symbol determining process is executed (B4). In short, the stop symbol determining program stored in the RAM 43 is executed to determine the scatter symbols 180 to be stopped in the symbol arrangement areas 151 to 155. Hence, a combination of scatter symbols 180 to be stopped in the symbol arrangement areas 151 to 155 is determined.
Afterwards, a scrolling process is executed to scroll the scatter symbols in the central display 4B at the same time (B5). The scrolling process is a process in which the scatter symbols 180 determined in B4 are stopped (rearranged) after scrolling the scatter symbols 180 in an upward/downward direction.
Next, the main CPU determines whether the scatter symbols 180 rearranged in the symbol arrangement areas 151 to 155 form a winning combination (B6). When it is determined that a winning combination is not formed (B6: NO), this routine ends.
On the other hand, when it is determined in B6 that a winning combination is formed (B6: YES), a payout process is executed (B7). That is, a payout-value of coins related to the number of scatter symbols 180 having a same type is calculated. When the coins to be paid out are stored, a predetermined number of credits are added to the credit-value stored in the RAM 43. On the other hand, when the coins are paid out, a control signal is transmitted to the hopper 66 to pay out a predetermined number of coins to the coin receiving portion 19.
Then, the main CPU determines whether a trigger symbol combination is formed or not (B8). The trigger symbol combination means a state where a predetermined number or more of the trigger symbols 180J are arranged in the symbol arrangement areas 151 to 155. When it is determined that a trigger symbol combination is not formed (B8: NO), this routine ends. On the other hand, when it is determined that a trigger symbol combination is formed (B8: YES), a feature game is run through the feature IN, based on the trigger symbol combination formed (B10). That is, when a trigger symbol combination includes the three or four trigger symbols 180J, a basic feature IN is formed. When five or more trigger symbols are arranged while being successively arranged in a row direction, a special feature IN is run. This routine ends thereafter.

After the process C6 or C8, the main CPU determines whether the spin button is ON (pressed) (C9). When the spin button is not pressed (C3: NO), the main CPU stands by until a player presses the spin button.
On the other hand, when the spin button is pressed (C9: YES), the main CPU executes a symbol determining process (C10) and executes a scrolling process of scrolling the scatter symbols 180 in the central display 4B at the same time (C11)
Then, the main CPU determines whether the scatter symbols 180 rearranged on the symbol arrangement areas 151 to 155 form a winning combination (C12). When it is determined that a winning combination is not formed (C12: NO), the main CPU reduces the feature game value N by “1” (C14). On the other hand, when it is determined in C12 that a winning combination is formed (C12: YES), the main CPU executes a payout process (C13) and the process C14.
When the feature game value N is reduced by “1” in C14, the main CPU determines whether the feature game number N is “0” or not (C15). When it is determined that the bonus game value N is not “0” (C15: NO), the main CPU returns to C9. On the other hand, when it is determined that the feature game value N is “0” (C15: YES), this routine ends.

Then, the main CPU determines whether a player presses the spin button (E3). When it is determined that the spin button is not pressed (E3: NO), the main CPU determines whether a predetermined period of time has elapsed since the count unit 123 has started timing (E4). When it is determined that a predetermined period of time has not elapsed (E4: NO), the main CPU causes the count unit 123 to continue timing (E5). Afterwards, the main CPU stands by until a player presses the spin button (E3). On the other hand, when it is determined in E4 that a predetermined period of time since the count unit 123 has started timing (E4: YES), the main CPU ends the feature game that is being run (E6). Afterwards, the main CPU causes the count unit 123 to stop timing (E7) and ends this routine.

In the present embodiment, the feature game includes the basic feature game and the special feature game. However, the invention is not limited thereto. For example, more kinds of feature games may be possible.
Further, in the present embodiment, the condition of setting the required bet amount in the feature game is as follows: when the three trigger symbols 180J are arranged, the required bet amount is “3 credits,” when the four trigger symbols 180J are arranged, the required bet amount is “2 credits” and when the five or more or three or more trigger symbols 180J are arranged while being successively arranged in a row direction, the required bet amount is “0 credit.” However, the invention is not limited to such condition. In the present invention, when the number of the trigger symbols 180J arranged or the required bet amount in the arrangement state is changed, it may be set that the number of trigger symbols 180J is 6 or more and the required bet amount is “0 credit.”
