Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to a game machine, such as a slot machine and, more particularly, to a game machine which enables a plurality of players to play games together and affords an incentive for playing a game.

[0002] Currently, a slot-type game machine 100 shown in FIG. 13 is a known game machine in which one player plays a game. In order to effect gaming, the game machine uses a game value, (e.g., tokens, paper currency, coins, or some form of credit medium, such as a credit card). When playing a game, a player inserts, e.g., a token into a token insert slot 101. In accordance with the number of inserted tokens, the player plays games. The related slot machine-type game machine 100 has a reservoir for inserted tokens. More specifically, when tokens are inserted via the token insert slot 101, the number of inserted tokens are counted one by one by a predetermined sensor. The count (credit) is then stored in a predetermined storage of the game machine. The thus-counted value is displayed on a display (not shown) which is to be provided at a predetermined location on the game machine and consists of a seven-segment LED display. The player actuates credit bet buttons 102a, 102b, and 102c, which will be described later, so as to bet a predetermined number of tokens on one or more desired winning lines, thereby rendering the winning line(s) effective and playing a game.

[0003] As shown in FIG. 13, the related game machine 100 of slot machine type has horizontally-oriented winning lines p1, p2, and p3; a lower-right-declining winning line p4; and a lower-left-declining winning line p5. As mentioned below, selection of the winning lines p1, p2, p3, p4, and p5 is performed in accordance with operation of the credit bet buttons 102a, 102b, and 102c, and the thus-selected winning lines are made effective.

[0004] When the credit bet button 102a is pressed once, the winning line p1 is selected and rendered effective. Every time the credit bet button 102a is pressed once, one credit (i.e., one token) is consumed, whereupon the number of credits bet on the winning line p1 is incremented by one credit (one token).

[0005] When the credit bet button 102b is pressed once, the winning lines p1, p2, and p3 are selected and rendered effective. Every time the credit bet button 102b is used once, three credits (i.e., three tokens) are consumed, whereupon the number of credits bet on the respective winning lines p1, p2, and p3 is incremented by one credit (i.e., one token).

[0006] When the credit bet button 102c is pressed once, the winning lines p1, p2, p3, p4, and p5; that is, all the winning lines, are selected and rendered effective. Every time the credit bet button 102c is pressed once, five credits (i.e., five tokens) are consumed, whereupon the number of credits bet on all the winning lines is incremented by one credit (one token).

[0007] If the player operates the credit bet button 102a, the player can bet a predetermined number of credits while taking an aim at only the winning line p1. Further, if the player operates the credit bet button 102b, the player can bet a predetermined number of credits while taking an aim at only the horizontally-oriented winning lines p1, p2, and p3. If the player operates the credit bet button 102c, the player can bet a desired number of credits on all winning lines.

[0008] More specifically, the player can strategically determine one or more winning lines to be made effective and the number of credits to be bet on the winning line(s), in accordance with the degree of the player's perceived luck at that time.

[0009] In the related slot machine type game machine 100, reels 111 through 113 start spinning as a result of depressing of a start lever 103. A predetermined number of symbols 121e . . . , 122e . . . , 123e . . . are drawn on an outer peripheral face of each of the reels 111 through 113.

[0010] After the start lever 103 has been actuated, the reels 111 through 113 continue spinning for a while. Subsequently, spinning of all the reels is automatically stopped.

[0011] If the symbols 121e . . . , 123e . . . drawn on the reels 111 through 113 are aligned with the winning line that has been selected and made effective by the player, so as to constitute a predetermined winning combination when all the reels 111 through 113 are stopped, the number of tokens corresponding to the winning combination are paid out to a token receiver 105 via a token payout hole 104.

[0012] Here, the predetermined winning combination is a meaning of identical symbols of the symbols drawn on all the reels 111 through 113 being aligned with the winning line. Specifically, symbols 7 or BELL are aligned with a winning line in such a manner as 7-7-7 or BELL-BELL-BELL.

[0013] The related slot machine type game machine 100 shown in FIG. 13 that has been described thus far is constructed on the assumption that a single player plays games on the machine, in consideration of the visibility, number, and dimensions of the respective reels 111 through 113.

[0014] As mentioned above, the related slot machine type game machine 100 is designed on the assumption that a single player plays games on the machine, and is not designed so that a plurality of players can play games on a single machine at the same time.

[0015] Even if a plurality of game machines 100 are disposed and a plurality of players play games, the game machines 100 are spaced a substantial interval apart from each other. Therefore, a player encounters difficulty in viewing symbols 121e . . . , 122e . . . , and 123e . . . drawn on the outer peripheral faces of the reels 111 through 113 of another machine. Moreover, players cannot play games as members of teams. Hence, the related slot machine type game machine produces a problem of a deficiency of entertainment or a failure to afford an incentive for playing games.

[0058] As shown in FIG. 1, the game machine 10 includes a reel spinning section 33, the 12 stations 34a through 34l, and an overhead section 37.

[0059] Individual sections of the game machine 10 will be described in detail.

[0060] The reel spinning section 33 has reels 1a through 1x; lamps 5, and a protective glass 36.

[0061] Each of the reels 1a through 1x has a substantially-circular cross-sectional profile and spins around a horizontal shaft while the circular center of the cross-sectional profile is taken as a center. A plurality of types of symbols 4 are drawn on an outer peripheral face 2 of each of the reels 1a through 1x. The reels 1a through 1x spin in the direction in which the symbols 4 move downward. In other words, as spinning, each of the reels 1a through 1x moves the symbols 4 vertically within a display window 3, thereby variably displaying the symbols 4.

[0062] As shown in FIG. 2, 24 reels; that is, the reels 1a through 1x, are arranged in a circular pattern such that the outer peripheral faces 2 of the reels oppose 12 players. Here, the reels 1a through 1x are arranged such that three reels are assigned each of the stations 34a through 34l.

[0063] In response to a lamp illumination signal output from the center unit 12 shown in FIG. 3, lamps 5 are illuminated at the beginning of a game, at the time of a gaming being played, and at the end of the game.

[0064] The protective glass 36 covers a circumferential exterior of the reel spinning section 33, thereby protecting the reels 1a through 1x.

[0065] In this embodiment, 24 reels; that is, the reels 1a through 1x, are employed. However, the number of reels is not limited to 24, and any number of reels may be employed, so long as three or more reels are employed.

[0066] In this embodiment, three reels are assigned to each of the stations 34a through 34l. However, the number of reels assigned to each station is not limited to three, and a required number of reels may be disposed. Any number of reels may be provided for each station, so long as one player can view all the reels provided for his station.

[0067] A plurality of speakers 32 are provided on the overhead section 37. The speakers 32 output sound via a sound circuit 31 in accordance with a sound signal output from the center unit 12 at the beginning of a game, at the time of a gaming being played, and at the end of the game.

[0068] The stations 34a through 34l are provided with station units 11a through 11l (shown in FIG. 3), and each of the stations 34a through 34l has a token insert slot 9, a monitor 6; button switches 7a, 7b, a token payout port 8, and a speaker 15.

[0069] The token insert slot 9 receives tokens inserted by the player.

[0070] Displayed on the monitor 6 are information about the number of inserted tokens; information about the symbols 4 to be displayed in the display window 3 during the course of spinning action of each of the reels 1a through 1x; information for informing players of prohibition of betting action, and image information performing presentation of games.

[0071] In accordance with pressing action of the player, the button switches 7a, 7b output a pressing signal to an input circuit.

[0072] When a win has been determined, tokens for payoff are paid via the token payout port 8.

[0073] In response to a sound signal output from each of the station units 11a through 11l, the speaker 15 outputs sound at the beginning of a game, at the time of a game being played, and at the end of a game.

[0074] Next, the configurations of the respective station units 11a through 11l and that of the center unit 12 will now be described by reference to FIG. 3.

[0075] The station units 11a through 11l and the center unit 12 are connected together via a data bus 16 having a width of 16 bits or 32 bits.

[0076] Each of the station units 11a through 11 is constituted of an image circuit 13, a token sensor 9a, an input circuit 14, and a sound circuit 38.

[0077] Position detection information about the reels 1a through information about the symbols 4 appearing when the reels 1a through 1x are stopped, and image information which provides presentation of games are input to the image circuit 13 from the center unit 12 via the data bus 16. The image circuit 13 produces an image signal on the basis of these information items, and symbol images of the reels 1a through 1x are output to the monitor 6.

[0078] The token sensor 9a detects the number of inserted tokens when tokens are inserted and outputs an inserted token count detection signal.

[0079] Input to the input circuit 14 are a press signal output from either of the button switches 7a, 7b and an inserted token count detection signal output from the token sensor 9a. The press signal is output to a CPU 25 via the data bus 16, and the inserted token count detection signal is output to RAM 21 via the data bus 16.

[0080] The sound circuit 38 outputs sound data to the speaker 15 after having converted the data into a sound signal.

[0081] The center unit 12 includes a sensor 17, a CD-ROM (compact disk read-only memory) drive 29, a hard disk driver 28, RAM (random access memory) 21, a switch 35, an input circuit 19, an output circuit 20, reel drive motors 18, a sound circuit 31, ROM (read-only memory) 22, a timer 30, a random number generator 26, an image circuit 23, a maintenance monitor 24, an advanced technology attachment packet interface circuit (hereinafter simply called an “interface circuit”) 27, and a CPU (central processing unit) 25.

[0082] The sensor 17 detects information about positions of the reels 1a through 1x when they are spinning and information about positions of the reels 1a through 1x when they are stationary.

[0083] The CD-ROM drive 29 sets image data to be used for performing presentation of a game.

[0084] The hard disk drive 28 sets information about results of games played at the respective stations 34a through 34l.

[0085] The RAM 21 sets information about the number of inserted tokens in response to the inserted token count detection signal and information about the symbols 4 appearing when the reels 1a through 1x have come to a standstill, as well as setting information about the combination of reels and information about winning lines in response to a press signal.

[0086] The switch 35 outputs an operation signal to the input circuit 19 in accordance with operations of an employee.

[0087] The input circuit 19 outputs the information detected by the sensor 17 and the operation signal output from a switch 35 to the CPU 25.

[0088] The output circuit 20 outputs a drive signal and a stop control signal to reel drive motors 18 and outputs a lamp illumination signal to the lamps 5.

[0089] The reel drive motors 18 spin the reels 1a through 1x in accordance with drive signals and perform control operation for stopping the reels 1a through 1x in accordance with stop control signals.

[0090] The sound circuit 31 outputs sound data to the speakers 32 after having converted the data into sound signals.

[0091] The ROM (read-only memory) 22 has a setting table in which are set combinations of symbols 4 to be used for determining wins.

[0092] The timer 30 measures a lapsed time and outputs a predetermined-period-of-time detection signal to the CPU 25 when a lapsed time has exceeded a predetermined period of time (i.e., a bet time).

[0093] The random number generator 26 randomly selects stop positions for the respective reels 1a through 1x by random numbers and determines the thus-selected positions. The random number generator 26 then outputs, to the CPU 25 as stop position information, the stop positions for the respective reels 1a through 1x determined through random selection.

[0094] The image circuit 23 converts the data, which are read by the CPU 25 and set in the hard disk drive 28 and the RAM 21, into an image signal and outputs the signal to the maintenance monitor 24.

[0095] In response to the image signal, the maintenance monitor 24 displays the information set in the hard disk drive 28 or the RAM 21.

[0096] The advanced technology attachment packet interface circuit (hereinafter simply called an “interface circuit”) 27 enables entry of image data set on CD-ROM loaded in the CD-ROM drive 29 and entry of game result information set in the hard disk drive 28.

[0097] Here, the CPU 26 performs processing pertaining to the following items (1) through (8).

[0098] (1) Position detection information about the reels 1a through 1x, information about the symbols 4 appearing when the reels 1a through 1x are stopped, and image information to be used for providing presentation of a game are output to the image circuit 13 via the data bus 16, and information about the symbols 4 appearing when the reels 1a through 1x are stopped, is set in the RAM 21.

[0099] (2) Sound data are output to the sound circuits 31, 38.

[0100] (3) A predetermined-period-of-time signal output from the timer 30 is input.

[0101] (4) A drive signal or a stop control signal is output to the output circuit 20 in accordance with the stop position information output from the random number generator 26.

[0102] (5) A lamp illumination signal is output to the lamps 5.

[0103] (6) In response to an operation signal output from the switch 35, the information set in the hard disk drive 28 or the RAM 21 is read via the interface circuit 27, and the thus-read information is output to the image circuit 23.

[0104] (7) Information about a combination of reels and information about a winning line are read from the RAM 21.

[0105] (8) The symbol information set in the RAM 21 is compared with the combination of symbols 4 which determines a win set in the ROM 22, and a determination is made as to whether or not the combination of symbols 4 to be displayed on the reels corresponding to the combination of reels set in the RAM 21 has constituted a winning combination along the winning line.

[0106] The operation of the game machine 10 will now be described by reference to FIGS. 1 through 4. FIG. 4 is a flowchart showing procedures of processing to be executed by the game machine 10.

[0107] First, when power of the game machine 10 is turned on, a system, such as the ROM 22, the RAM 21, and the hard disk drive 28, all being provided in the center unit 12, is inspected.

[0108] Subsequently, the CPU 25 outputs a drive signal to the reel drive motor 18, thereby starting spinning of the reels 1a through 1x. As a result, there is started an operation for displaying the symbols 4 such that the symbols 4 are moved vertically downward within the display window 3.

[0109] Simultaneously, the timer 30 starts measuring a lapsed time. Here, a player P of the station 34a can insert tokens into the token insert slot 9 until the lapsed time reaches a predetermined period of time. Further, the player can select and make effective a desired winning line by actuating the button switches 7a, 7b and bet a desired number of credits on the thus-selected winning line.

[0110] During the course of spinning of the reels 1a through 1x, the sensor 17 sequentially outputs the detected position detection information about the reels 1a through 1x to the monitor 6, via the data bus 16 and by the CPU 25. Information about the symbols 4 appearing in the display window 3 during the spinning action of the reels 1a through 1x is displayed on the monitor 6 (step 1).

[0111] In step 2, a determination is made as to whether or not a lapsed time has exceeded a predetermined period of bet time.

[0112] When the lapsed time has exceeded a predetermined period of time (when YES is selected in step 2), the timer 30 outputs a predetermined-period-of-time detection signal to the CPU 25, whereby information for informing the player of prohibition of betting action is displayed on the monitor 6. Processing then proceeds to step 3. In contrast, if the lapsed time has not yet exceeded the predetermined period of time (when NO is selected in step 2), processing again returns to step 1.

[0113] Stop positions for the reels 1a through 1x determined by the random number generator 26 are input to the CPU 25 as stop position information. The CPU 25 outputs a stop control signal to the reel drive motor 18, thereby stopping the spinning operations of the reels 1a through 1x and stopping moving display of the symbols 4. Then, the sensor 17 outputs information about the stop positions for the reels 1a through 1x to the CPU 25 via the input circuit 19 (step 3).

[0114] In step 4, the CPU 25 determines whether or not the spinning operations of the reels 1a through 1x have been completed, on the basis of the stop position detection information about the reels 1a through 1x. When the reels 1a through 1x are determined to have finished spinning (when YES is selected in step 4), information about the symbols 4 appearing when the reels 1a through 1x have come to a standstill is set in the RAM 21 by the CPU 25. The CPU 25 outputs the information to the monitor 6 via the data bus 16, and processing proceeds to step 5. In contrast, when the reels 1a through 1x are determined to have not yet finished spinning (when NO is selected in step 4), processing again proceeds to step 3.

[0115] In step 5, the CPU 25 reads a combination of reels 1a through 1x from the RAM 21, and the symbol information set in the RAM 21 is compared with a combination of symbols to be used for determining a win, the combination being set in the ROM 22. As a result, a determination is made as to whether or not a combination of symbols 4 to be displayed on the reels 1a through 1x has constituted a winning combination along a winning line 51. When the combination of symbols 4 is determined to have constituted a winning combination along the winning line 51, tokens for payoff are paid from the token payout port 8 of the station 34a in accordance with the number of bet tokens.

[0116] In step 6, the CPU 25 determines whether or not payout of the tokens has been completed. When payout of the tokens is determined to have been completed (when YES is selected in step 6), processing proceeds to step 7. However, when payout of the tokens is determined to have not yet been completed (when NO is selected in step 6), processing again returns to step 5.

[0117] In step 7, the CPU 25 determines whether or not any station has generated a bonus game, thereby determining whether to perform a bonus game. If a bonus game is determined to be performed (when YES is selected in step 7), processing proceeds to step 8. However, if the bonus game is determined not to be performed (when NO is selected in step 7), processing proceeds to step 9.

[0118] In step 8, a bonus game is executed as a result of the CPU 25 performing processing similar to those pertaining to steps 1, 3, 4, and 5. Predetermined tokens for payoff are paid out from the token payout port 8 of the station of the player P for which a win has been determined.

[0119] In accordance with a press signal output as a result of the player P having pressed the button switch 7a, the CPU 25 determines whether or not the player P continues playing games (step 9). If the player P is determined to continue playing games (when YES is selected in step 9), processing again returns to step 1. In contrast, when the player P is determined not to continue playing games (when NO is selected in step 9), processing to be executed by the game machine 10 is terminated.

[0120] As mentioned above, according to the first embodiment, the game machine includes the plurality of reels 1a through 1x, and the outer peripheral faces 2 are oriented so as to oppose a plurality of players P . . . Further, the reels 1a through 1x are arranged along a curve or a straight line. Hence, the plurality of players P can simultaneously view the symbols 4 provided on the outer peripheral faces 2 of the respective reels 1a through 1x. Hence, the players can play games in conjunction with each other. As a result, entertainment is afforded to all the players, thereby giving the players an incentive for playing games.

[0121] When tokens are inserted, the token sensor 9a detects the number of inserted tokens. An inserted token count detection signal is output to the monitor 6 via the input circuit 14 and the image circuit 13. Further, the signal is output to the RAM 21 and the ROM 22 via the data bus 16.

[0122] As a result, information about the number of inserted tokens is displayed on the monitor 6 and set in the RAM 21, and information about the winning line 51 is read from the ROM 22.

[0123] By reference to FIG. 5, an example of winning line will be described. FIG. 5 describes an example in which each of the stations 34a through 34l employs three reels, and in which a maximum of eight winning lines can be made effective. In FIG. 5, an explanation is given on the winning line to be afforded to a player of the station 34a. Explanations of winning lines to be afforded to other stations 34b to 34l are omitted.

[0124] The station 34a sets eight winning lines 51 through 58. The button switches 7a, 7b correspond to the winning lines 51 through 58. A desired winning line is selected and made effective by actuating the button switches 7a, 7b, and a desired number of credits can be bet on the thus-selected winning line.

[0125] By reference to FIG. 6, a configuration for establishing winning lines 56 through 58 in the vertical direction will now be described supplementally.

[0126] For convenience of explanation, FIG. 6A shows the annularly-formed reels 1a through 1x which are developed in the form of a plane. In order to establish a combination of symbols 4 along any one of the winning lines 56 through 58 provided in the vertical direction, a plurality of identical symbols 4a through 4c are continuously drawn on the outer peripheral faces 2a of the respective reels 1a through 1x, as shown in FIG. 6A.

[0127] FIG. 6B shows modes of stoppage of the reels 1a through 1x on which are drawn the symbols 4a through 4c shown in FIG. 6A. More specifically, there is shown a combination of symbols 4 which are viewed by the player via the display window 3 when the reels have come to a standstill. FIG. 6B shows six stopped states 6A through 6F of the reels 1a through 1c when viewed from left to right. As sight is shifted from 6A to 6F, a left reel is stopped while symbols are advanced from those of an adjacent right reel by one.

[0128] When the reels 1a through 1x are stopped along a stop position 6D shown in FIG. 6B as a result of random sampling of the random number generator 26, the symbols 4a through 4c are displayed within the display window 3, thereby constituting a win by the combination of symbols 4a through 4c along the vertical winning lines 56 through 58.

[0129] The foregoing descriptions are described an example in which combinations of three reels are employed. The number of reels to be combined together may be changed by pressing of the button switch 7a.

[0130] For instance, in the case of description of the station 34a shown in FIG. 5, the number of reels to be combined together is set to three as an initial setting. More specifically, if the player P performs no operation, a combination of reels 1a, 1b, 1c is determined.

[0131] When the button switch 7a is pressed during a period of bet time, the number of reel combinations is increased. Specifically, when the button switch 7a is pressed once, the reel 1d situated adjacent to the reel 1c and the reel 1x situated adjacent to the reel 1a are added. The player P of the station 34a can play games by a combination of five reels; that is, the reels 1x through 1d, during the course of games. When the button switch 7a is pressed again, the reels 1e and 1y are added to the combination of reels. Then, the player can play games with use of combinations of seven reels; that is, the reels 1y through 1e. Any number may be selected for combinations of reels, as required, so long as the reels fall within a view R of one player P.

[0132] In this example, when the button switch 7a is pressed three times, processing returns to an initial setting. Specifically, the number of reel combinations can be changed in a cyclical manner from three to five, from five to seven, and from seven to three when the button switch 7a is pressed successively.

[0133] In accordance with a change in the number of combinations of reels, the length of winning lines in the horizontal direction can also be changed. At that time, in accordance with a change in the number of reel combinations, positions where the winning lines are set and the number of winning lines may also be changed.

[0134] The number of bet tokens to be consumed may be increased with an increase in the number of reel combinations. At that time, the number of winning lines to be set is increased, thereby increasing the number of winning lines which can be made effective. As a result, there is added an entertainment feature of strategically selecting the number of reel combinations on the basis of the player's perception of occasionally having good luck. Consequently, this can give the player P an incentive for increasing the number of tokens to be consumed.

[0135] The press signal is output to the RAM 21 via the input circuit 14 and the data bus 16 in response to the pressing actions of the button switches 7a, 7b. As a result, information about combinations of reels is set in the RAM 21.

[0136] In the first embodiment shown in FIG. 5, as mentioned above, the reels are constructed so as to become shared among the player P of the station 34a, a player P of the adjacent station 34b, and a player P of another adjacent station 34l. In the initial setting, the reels 1a and 1c are shared reels. As mentioned previously, as a result of pressing of the button switch 7a, the reels 1d and 1x and the reels 1e and 1y are added as shared reels.

[0137] As mentioned above, according to the invention, a plurality of reels “a” through “x” are provided. Further, display faces of the reels are oriented so as to oppose a plurality of players. The reels are also arranged along a curve or a straight line. As a result, a reel can be shared among the station 34a and the adjacent station 34b or the adjacent station 34l. Accordingly, shared winning lines can be set between the station 34a and the adjacent station 34b or 34l. In short, the winning lines 56 and 58 shown in FIG. 5 are the shared lines.

[0138] Consequently, when the player P of the station 34a is betting credits on the winning line 56, the player P of the adjacent station 34b can also bet credits on the winning line 56 simultaneously. If the symbols 4a, 4b, and 4c are aligned with the shared winning line 56, both players definitely gain a win.

[0139] Consequently, tokens for payoff are paid out from the token payout port 8 of the station 34a and that of the station 34b. As a result, the adjacent players can share the pleasure of a win.

[0140] The player P of the station 34a bets credits on the shared winning line 56. As a matter of course, the player P of the station 34b may wait for the next chance of betting credits.

[0141] At that time, the player P of the station 34b who has not bet any credits on the shared winning line 56 feels interested in a result of a win afforded to the winning line 56 shared between the player P of the adjacent station 34a and that of the station 34b. For instance, when a win has arisen in the winning line 56, the player P of the station 34b who has not bet credits on the shared winning line feels regret. Therefore, the player P feels that he has lost a chance. Hence, in order to avoid a regrettable feeling of having lost another chance, the player is motivated to bet credits on as many winning lines as possible; or all winning lines, if possible. Consequently, profits of the game machine are increased.

[0142] By arranging shared reels at positions between adjacent stations, there is achieved another effect for shortening spaces between the stations by amounts corresponding to the shared reels. In view of limitations on the space of an amusement arcade, the size of the game machine cannot be made large indiscriminately. In this respect, shared reels are arranged effectively, thereby enabling an increase in the number of stations. Thus, profits of the game machine are increased.

[0143] FIG. 7 shows second embodiment of setting of the winning lines. In this embodiment, at least one symbol is shared between the winning line of a player and that of another, adjacent player.

[0144] For instance, as shown in FIG. 7, the player P of the station 34a makes a winning line 90 effective, and the player P of the station 34b makes the winning line 89 effective.

[0145] Since an overlap exists between the winning lines 89 and 90 on the reel 1c, the symbol 4x becomes a shared symbol.

[0146] When the moving display of the symbols 4 is stopped, the symbols 4 provided on the outer peripheral faces 2 of the respective reels 1c through 1e are aligned with the winning line 89, to thereby constitute a predetermined winning combination (i.e., “O” shown in FIG. 7). However, the symbols 4 provided on the outer peripheral faces 2 of the reels 1a through 1c are not aligned with the winning line 89 and fail to constitute a predetermined winning combination.

[0147] In this case, as a matter of course, tokens for payoff are paid to the player P of the station 34b. The symbol 4x (“O” shown in FIG. 7) located at a point on the reel 1c where an overlap exists between the winning lines 89 and 90 is taken as a shared symbol and is set in the ROM 22 beforehand. In step 5 shown in FIG. 4, the CPU 25 compares information about the symbols set in the RAM 21 with the shared symbol 4x set in the ROM 22, to thereby determine occurrence of a match therebetween. A certain amount of tokens for payoff are also paid to the player P of the station 34a.

[0148] As a result, the player observes a winning line which has been made effective by another adjacent player and considers setting of a winning line in consideration of the shared symbol corresponding to the winning line. Players become able to enjoy playing games according to a strategy.

[0149] In the above descriptions, a plurality of reels are provided, and display faces of the reels are arranged so as to oppose a plurality of players. Further, the reels are arranged along a curve or a straight line. In addition, shared reels are also provided. As a result, the player P shares a game space with adjacent players P. Thus, an entertainment feature of sharing games is realized.

[0150] Realization of shared winning lines can be made possible without use of the previously-stated shared reels.

[0151] A third embodiment in which winning lines are shared without use of shared reels will be described hereinbelow by reference to FIGS. 8A and 8B.

[0152] In this embodiment, a total of 24 reels are provided, as in the case of the previous embodiment. Display faces of the reels 1a through 1x are arranged so as to oppose a plurality of players and are arranged along a curve or straight line.

[0153] In this embodiment, reels provided for the respective stations 34a through 34h are not provided with reels to be shared between adjacent stations. Therefore, a total of eight stations are provided.

[0154] With a view toward describing a relationship between reels and winning lines, FIGS. 8A and 8B illustrate the reels 1a through 1x to be provided for the station 34a and the stations 34b and 34h provided on the respective sides thereof. More specifically, a total of nine reels are illustrated; that is, the reels 1f, 1e, 1d, . . . 1x, 1w, and 1v, when viewed from left to right.

[0155] FIGS. 8A and 8B are drawings showing, in an easily understandable manner for the sake of convenience, independent winning lines and winning lines to be shared.

[0156] FIG. 8A illustrates only independent winning lines. FIG. 8B illustrates only winning lines to be shared. These drawings are prepared separately for the sake of convenience of comprehension. Independent winning lines and winning lines to be shared are not separate from each other but are combined together in the game machine.

[0157] As mentioned above, FIG. 8A shows independent winning lines. In the third embodiment, five independent winning lines are set for each of the stations. More specifically, an explanation is given of the station 34a, and three horizontally-extending winning lines 80a, 80b, and 80c and the obliquely-extending winning lines 80d and 80e constitute five independent winning lines.

[0158] The player P makes effective one or more arbitrary winning lines from among the winning lines 80a through 80e, by betting credits on the winning line through pressing of the button switch 7a. Moreover, the player P can set an arbitrary number of credits on the winning line(s) thus made effective, by pressing the button switch 7a.

[0159] In the third embodiment, the player P can bet credits on a shared winning line other than an independent winning line.

[0160] FIG. 8B shows shared winning lines in the manner mentioned above. In the third embodiment, five shared winning lines are set between adjacent stations 34.

[0161] Shared winning lines will be described by reference to the shared winning lines 80f through 80j set between the stations 34a and 34b.

[0162] FIG. 8B illustrates shared winning lines 80f through 80j existing between the stations 34a and 34b. The shared winning lines 80f, 80g, and 80h are horizontally-extending straight lines. More specifically, the shared winning line 80f interconnects upper symbols 4 from among symbols 4 drawn on the four reels 1e, 1d, 1c, and 1b, in the form of a horizontally-extending straight, continuous line. The shared winning line 80g interconnects middle symbols 4 from among symbols 4 drawn on the four reels 1e, 1d, 1c, and 1b, in the form of a horizontally-extending straight, continuous line. Further, the shared winning line 80h interconnects lower symbols 4 from among symbols 4 drawn on the four reels 1e, 1d, 1c, and 1b, in the form of a horizontally-extending straight, continuous line.

[0163] The shared winning lines 80i, 80j are horizontally-oriented lines, as in the case of the shared winning lines 80f through 80j. However, portions of the shared winning lines 80i, 80j are bent. More specifically, the shared winning line 80i is a winning line that interconnects the upper symbol 4 provided on the reel 1e, the middle symbols 4 provided on the reels 1d, 1c, and the upper symbol provided on the reel 1b. Moreover, the shared winning line 80i is a winning line for interconnecting the lower symbol 4 provided on the reel 1e, the middle symbols 4 provided on the reels 1d, 1c, and the lower symbol 4 provided on the reel 1b.

[0164] The player P of the station 34a and the player P of the station 34b can bet credits on the shared winning lines 80f through 80j. More specifically, the player P of the station 34a and the player P of the station 34b can also make effective one or more arbitrary winning lines of the winning lines 80f through 80j, by pressing the button switch 7a. Similarly, the player P can bet an arbitrary number of credits on the winning line(s) having been made effective, by pressing the button switch 7a.

[0165] For instance, the players P of the stations 34a and 34b are assumed to make the shared winning line 80f effective by betting credits on the line through pressing of the button switch 7a. Then, set in the RAM 21 are data representing that the players P of the stations 34a and 34b have bet credits on the shared winning line 80f.

[0166] When the moving display of the symbols 4 is stopped, the symbols 4 provided on the outer peripheral faces 2 of the reels 1b through 1e are aligned with the shared winning line 80f, thereby constituting a predetermined winning combination of symbols. The CPU 25 compares the symbol information set in the RAM 21 with a combination of symbols 4 which determines a win set in the ROM 22, thereby determining that a predetermined winning combination of symbols has been constituted along the winning line 80f (step 5 shown in FIG. 4). As a result, tokens for payout are paid from the token payout ports 8 of the respective stations 34a, 34b. Consequently, adjacent players can share the pleasure of a win.

[0167] In the embodiment, three symbols 4 attached to the outer peripheral faces 2 of the respective reels 1a through 1x are displayed within the display window 3. However, the number of symbols to be displayed is not limited to three; a desired number of symbols may be displayed. The player P can easily view processes during which a winning combination of symbols is constituted, by displaying a larger number of symbols 4 within the display window 3, thereby affording the player p an expectation for determination of a win or tension.

[0168] In the embodiment, the reels 1a through 1x are arranged in a circular pattern. However, the shape of the reels is not limited to a circular pattern. In the invention, as shown in FIG. 9, a plurality of reels 1′ . . . may be arranged along a curve L2 or a straight line L1.

[0169] As shown in FIG. 10, according to the invention, a plurality of reels 1″ . . . may be arranged along a substantially-closed curved line W′ consisting of straight lines and curves.

[0170] In the embodiment, the reels 1a through 1x are used. However, belts may also be employed. Use of belts enables a reduction in the depth of the reels 1a through 1x. Hence, belts larger in number than the reels 1a through 1x may be arranged. Further, the belts have smaller inertial masses, and hence the braking characteristic of the display is improved accordingly.

[0171] As shown in FIG. 11, in the embodiment, 24 reels 1a′ through 1x′ may also be provided below and in parallel with the reels 1a through 1x. Specifically, according to the invention, a plurality of reels may be vertically provided in two or more layers. As a result, complicated combinations of symbols 4 are achieved, thereby improving the entertainment nature of games to a much greater extent.

[0172] The embodiments have described on the assumption that the reels 1a through 1x have mechanical constructions. However, the reels are not limited to the mechanical construction. There can also be included dummy reels which are constituted by displaying symbols made of computer-graphic (CG) images on an image display device, such as those listed below.

[0173] Examples of the image display device can include, e.g., a liquid-crystal display, a CRT (cathode-ray tube), and a display device, such as a DLP (digital light processing) projector using an image display element DMD (digital mirror device). Symbols based on CG images are cyclically displayed in a vertical direction on the image display device, thereby constructing the dummy reels on the image display device.

[0174] In the embodiment, the reels 1a through 1x are spun, respectively, thereby displaying the symbols 4 in a manner sequentially moving vertically. However, the symbols 4 may also be displayed so as to move in oblique direction.

[0175] For instance, in a case where liquid-crystal displays 201 through 221 shown in FIG. 12 are used in place of reels, symbol images 4′ appearing on the display screen 2′ of the liquid-crystal displays 201 through 221 are displayed so as to sequentially move in the directions of arrows shown in FIG. 12.

[0176] When the symbol images 4′ are displayed so as to move sequentially in oblique direction, players can view the symbol images 4′ as if displayed helically. Hence, an attraction of visual games can be afforded to a player.
