00 Alternatively, it is possible to make the entire front panel 31 as the display screen 31a without forming the design pattern formation Sregion 31b in the front panel 31. In this case, either the design patterns are not formed on the display plate 33 or the display plate 33 is omitted.

Note that, in Fig. 5 and Fig. 6, electric circuits and the like for operating the various display units 48 to 50 that are arranged on the back side of the display plate 33 are not shown.

The transparent liquid crystal panel 34 is formed by inserting liquid crystal into a gap portion between a transparent substrate such as a glass plate or the like on which a thin film transistor layer is formed, and another transparent substrate facing against that transparent substrate. The display mode of the transparent liquid crystal panel 34 is set to be normally white. The normal white indicates that it becomes a white display (in which lights transmitting to the display screen side are visible from the outside) in a state where the liquid crystal is not activated. By adopting the transparent liquid crystal panel 34 that is set to be normally white in this way, even in the case where the situation where the liquid crystal cannot be activated occurs, the scrolling display and the stopping display of the symbols on the mechanical reels 3A to 3E can be made visible. For this reason, the player can continue the game. Namely, even in the case where the situation such as that described above occurs, it is still possible to play the game centered around the rearrangement of the symbols on the mechanical reels 3A to 3E.

The light guiding plate 35 is for guiding the lights from the O fluorescent lamps 37a and 37b to the transparent liquid crystal panel 34 (in other words, for illuminating the transparent liquid crystal 00 O panel 34). The light guiding plate 35 is provided on the back side of the transparent liquid crystal panel 34, and formed by a transparent element (having a light guiding function) of acrylic resin or the like 00 having a thickness of about 2 cm, for example.

The reflection film 36 is for reflecting the lights guided by the Slight guiding plate 35 toward the front side of the light guiding plate 35. The reflection film 36 is a white polyester film or aluminum thin film with a silver vaporization film formed thereon. The reflection film 36 is formed by a reflective region 36A and a non-reflective region (transmitting region) 36B. The non-reflective region 36B is formed by a transparent material, and provided in a region containing a portion for covering a front side of the mechanical reels 3A to 3E in the front panel 31.

The fluorescent lamps 37a and 37b are arranged along an upper end portion and a lower end portion of the light guiding plate 35, and their both ends are supported by the lamp holders 39a and 39b, 39g and 39h, respectively. The lights emitted from the fluorescent lamps 37a and 37b are reflected by the reflective region 36A of the reflection film 36 and will illuminate the transparent liquid crystal panel 34.

The fluorescent lamps 38a and 38b are arranged toward the mechanical reels 3A to 3E at an upper position and a lower position on the back side of the reflection film 36, and their both ends are supported by the lamp holders 39c and 39d, 39e and 39f, respectively. The lights emitted from the fluorescent lamps 38a and 38b, reflected at the surfaces of the mechanical reels 3A to 3E and entered into the non-reflective region 36B will illuminate the transparent liquid crystal panel 34. In this way, in the liquid crystal display 30, the light emitted from the fluorescent lamps 37a and 37b and reflected C-i by the reflective region 36A of the reflection film 36 and the lights t emitted from the fluorescent lamps 38a and 38b, reflected at the 0 surfaces of the mechanical reels 3A to 3E and entered into the 00 O non-reflective region 36B will illuminate the transparent liquid crystal panel 34. Consequently, a region of the liquid crystal display corresponding to the non-reflective region 36B of the reflection 00 film 36 becomes a region which can be switched between c-i transparent/non-transparent states according to whether the liquid crystal is activated or not. On the other hand, a region of the liquid crystal display 30 corresponding to the reflective region 36A of the reflection film 36 is in a non-transparent state regardless of whether the liquid crystal is activated or not.

In the slot machine 13, only one region of the display screen 31a of the liquid crystal display 30 is set as a region that can be switched between the transparent/non-transparent states, but it is also possible to set the entire region of the display screen of the liquid crystal display 30 as a region that can be switched between the transparent/non-transparent states. In the case of setting the entire region of the liquid crystal display 30 as a region that can be switched between the transmissive/non-transmissive states in this way, the reflection film 36 is entirely formed by the non-reflective region 36B or the reflection film 36 is omitted.

The JP display unit 75 displays the amount to which 0.5% of credits among the credits bet at a total 12 locations of the slot machines 13 and the second game terminals are accumulated. Then, when a prescribed condition is realized by C- a JP bonus game which occurs at a prescribed timing, it becomes the win of JP. Then, the credit amount of JP is paid out, and the JP display C unit 75 for the paid out JP will display a numerical value of an initial 00 value (50,000 credits, for example).

On the betting board 71, chip marks 76 for indicating the number of chips and the BET area 73 that are bet until that time are displayed.

00 The number displayed on the chip mark 76 indicates the number of bet chips. For example, as shown in Fig. 9, the chip mark 76 of placed at an intersection of grids and indicates that it covers four numbers of and and one chip is bet. A method for betting that covers four numbers in this way is a betting method called "corner bet".

The chip mark 76 of "20" placed on a grid "2 to 1" indicates that it covers 12 numbers of a column of and so one, and 20 chips are bet. A method for betting that covers 12 numbers by using a grid written as "2 to 1" in this way is a betting method called "column bet".

The other betting methods include a "straight bet" for betting only on one number, a "split bet" for covering two numbers by betting on a line between two numbers, a "street bet" for covering three numbers "14" and for example) by betting at an edge of one row of numbers (one column in a vertical direction in Fig. a "five bet" for covering five numbers and by betting on a line between "00" and a "line bet" for covering six numbers "16"11, "17" and for example) by betting between numbers of two rows (two columns in a vertical direction in Fig. 9), and a "dozen bet" for covering 12 numbers by betting on a grid written as "lstl2", "2nd12" or "3rd12". In addition, there are "red/black" for betting on the color of the number display plate 64 ("red" or "black"), "even/odd" for betting on the odd numbers or the even numbers, and "low/high" for covering 18 numbers by betting on the numbers less than or equal to 18 or the numbers greater than or equal to 19. Here, U these plurality of betting methods have different payout amounts of O credit per one chip (payout rates) when the bet chips win.

Fig. 13 is showing a basic game random number table to be used by the basic game of the slot machine 13 which will be explained by Fig.

19 to be described below. In this basic game random number table, a range of random numbers and a winning probability are registered in correspondence for each specific combination for awarding a prize.

For this reason, in the combination determination processing (step S5 of Fig. 19) to be described below, the generation of the specific combination for awarding a prize of "BONUS" as an eventual basic game result in a case where a random number in a range of to "999" among random numbers of to "65535" is extracted, for example, is determined inside the slot machine 13. In other words, the probability for having a combination of stopped symbols determined as the specific combination for awarding a prize of "BONUS" becomes "1000/65535". Also, C-i the generation of the specific combination for awarding a prize of o as an eventual basic game result in a case where a random number O in a range of "2000" to "3499" among random numbers of to "65535"

O

00 O is extracted, for example, is determined inside the slot machine 13.

In other words, the probability for having a combination of stopped symbols determined as the specific combination for awarding a prize 00 of becomes "1500/65535". On the other hand, the generation of a lost game as an eventual basic game result in a case where a random Snumber in a range of "10000" to "65535" among random numbers of "0" to "65535" is extracted, for example, is determined inside the slot machine 13. In other words, the probability for having a combination of stopped symbols determined as a combination indicating a lost game becomes "55536/65535".

Fig. 14 is showing a basic game payout table to be used in the basic game which will be explained by Fig. 19 to be described below. In this basic game payout table, the specific combination for awarding a prize and a number of coins to be paid for each credit amount bet in one game are registered in correspondence. For this reason, at a time of judging whether it is the specific combination for awarding a prize or not, in the case where the combination of is generated, 10 coins will be paid when the BET credit amount is 20 coins will be paid when the BET credit amount is and 30 coins will be paid when the BET credit amount is For example, in the case where the combination of "BONUS" is generated, 100 coins when the BET credit amount is 200 coins when the BET credit amount is and 300 coins when the BET credit amount is will be transmitted to the center controller 14 as the credit data, and become usable as the credit in the second game to be described below.

Figs. 15 to 18 show examples of second game payout tables used in the roulette game which will be described later by referring to Figs.

to In the second game payout table, an allowed range of the betting methods and a presence/absence of an allowance for multiple bets are 0 registered for each terminal. Here each terminal implies the following 00 three cases. One is the slot machine 13 which made a transition to the roulette game as a combination for awarding a prize of "BONUS" is stopped and displayed on the payline (hereafter referred to as a 00 main slot machine 13). Another one is the slot machine 13 which has (1 not made a transition to the roulette game as a combination of "BONUS" Sis not stopped and displayed on the payline by this slot machine 13 1C 0 itself but it joins the roulette game to be started by the main slot machine 13 (hereafter referred to as a joining slot machine 13). Still another one is the second game terminal The second game payout table is configured such that the allowed range of the betting methods is different according to the credit amount bet in the basic game when a combination for awarding a prize of "BONUS" is generated, for the main slot machine 13.

For example, in the case where the credit amount bet when a combination for awarding a prize of "BONUS" is generated in the main slot machine 13 is the betting methods by which the bet can be made in the roulette game are at least one of "straight bet", "split bet", and "street bet". Namely, the multiple bets are allowed for the main slot machine 13. Consequently, "straight bet" may be made at a plurality of places, or both of "straight bet" and "split bet" may be made. The betting method by which the bet can be made in the roulette game by the joining slot machine 13 is one of "dozen bet", "column bet", "red/black", "even/odd" and "low/high". Namely, the multiple bets are not allowed for the joining slot machine 13, so that it can only bet at one place among the BET areas 73 of the BET screen 70 in the present embodiment.

When it is determined to execute the second game on the slot machine 13, the payout of the second game on the slot machine 13 is changed C-i according to the BET status of the second game terminals 15. The BET O status means, for example, the number of persons betting on one player who has won for the second game, and its bet amount in the second game 00 O (hereinafter also referred to as a joining game) which is executed on the second game terminals 15. In this embodiment, the second game payout tables may be prepared stepwise according to the number of 00 persons betting on a player who has won for the second game on the slot machine 13.

SFigs. 16 to 18 are examples of the second game payout tables changed according to bets made using the second game terminals In Fig. 16, the payout rates of the second game are increased to times those of a normal case (Fig. 15), according to bets made using the second game terminals 15. In addition, in Fig. 17, the payout rates of the second game are increased to twice those of the normal case (Fig. Moreover, in Fig. 18, the allowable number of betting methods in the second game to be executed on the slot machine 13 is set so as to increase according to bets made in the second game using the second game terminals 15. To be more precise, even in the case of credit amount 1, "corner bet," "five bet," "line bet," "dozen bet," and "column bet" are allowed. Furthermore, the upper limit of a bet amount in the second game to be executed on the slot machine 13 is set so as to increase according to bets made using the second game terminals Specifically, BET credit amounts 4 and 5 are allowed. In the cases of the credit amounts 4 and 5, the allowable range of betting methods increases, and payout rates of the second game can be increased to or 2 times those of the normal case (Fig. Fig. 15 to Fig. 18 are only showing one example in the present embodiment, and the payout rate for each BET area 73 of the BET screen 70 stored in this payout credit memory area may be made to be different for the slot machines 13 and for the second game terminals 15. It may be made to be different for the main slot machine 13 and the joining slot machine 13 even among the slot machines 13.

O

0 In one example shown in Fig. 15 to Fig. 18, the limitation is put 00 on the betting methods according to the credit amount bet in the basic game of the main slot machine 13, but besides that, it may be made to determine the rate according to the credit amount bet in the basic 00 game of the main slot machine 13. It may be made to allow the use of coins of the slot machine 13 as additional credit at a time of playing Sthe roulette game and change the rate according to the additional credit 1C 0 amount, or it may be made to change the rate according to the total betting amount.

As in the second game payout table shown in Fig. 15, the payout rate for the roulette game is set to be relatively high, so that a high payout can be expected depending on the betting method of the player.

Fig. 16 is a flow chart showing a flow of processing operations in the basic game to be executed by the controller 100 of the slot machine 13. This program will be executed by being called up at a prescribed timing from the main program of the slot machine 13 which is already being executed. The main program is a program for controlling overall operations of the slot machine 13.

In the following, it is assumed that the slot machine 13 is activated in advance, the variables to be used in the CPU 106 of the controller 100 side are initialized to prescribed values, and as a result the slot machine 13 is normally operating.

The CPU 106 of the controller 106 side judges whether the credit which is the remaining number of coins entered by the player is remaining or not (step Si) More specifically, the CPU 106 reads out the credit amount C stored in the RAM 110, and carries out the processing according to this read out credit amount C. In the case where the credit amount C is (step S1 NO), the CPU 106 cannot start the game, so C-i that it finishes this routine without carrying out any processing.

O On the other hand, in the case where the credit amount C is greater than or equal to (step Si YES), the CPU 106 judges that there is 00 O a remaining credit, and shifts the processing to the step S2.

When it is shifted to the step S2, the CPU 106 judges whether the r pressing operation of the spin/repeat/bet switch 24 is carried out 00 or not. In the case where the spin/repeat/bet switch 24 is pressed C' and the operation signal from the spin/repeat/bet switch 24 is inputted in conjunction with this (step S2 YES), the CPU 106 shifts the processing to the step S12. On the other hand, in the case where the operation signal from the spin/repeat/bet switch 24 is not inputted even after a prescribed time has elapsed (step S2 NO), the CPU 106 judges that the spin/repeat/bet switch 24 is not pressed, and shifts the processing to the step S3.

When it is shifted to the step S3, the game condition is set. More specifically, the CPU 106 determines the number of coins to be bet on the payline in this game, according to the operation of the BET switch 23. At this point, the CPU 106 receives the operation signal generated as the operation of the BET switch 23 is carried out, and stores the BET number regarding the payline into a prescribed memory region of the RAM 110 according to the number of times by which this received operation signal is received. The CPU 106 reads out the credit amount C written in a prescribed memory region of the RAM 110, subtracts the total BET number in which the above described BET number is added, from this read out credit amount C, and stores this subtracted value into a prescribed memory region of the RAM 110. After that, the CPU 106 shifts the processing to the step S4.

When it is shifted to the step S4, the CPU 106 judges whether the start switch 25 is ON or not, and waits for having the start switch 25 operated. In the case where the start switch 25 is operated and the operation signal from the start switch 25 is inputted in conjunction C- with this (step S4 YES), the CPU 106 judges that the start switch is operated, and shifts the processing to the step On the other hand, when it is shifted to the step S12, the CPU 106 00 O judges whether the value of the credit amount C is greater than or equal to the value of the total bet amount in the previous game or not. In other words, the CPU 106 judges whether it is possible to start 00 the game as the spin/repeat/bet switch 24 is pressed. More specifically, when the spin/repeat/bet switch 24 is pressed and the operation signal Sfrom that switch 24 is inputted in conjunction with this, the CPU 106 reads out the credit amount C and the BET numbers regarding the paylines L1 to L9 in the previous game which are written in a prescribed memory region of the RAM 110, and carries out the processing according to whether the value of the credit amount C is greater than or equal to the value the total bet amount in the previous game or not, according to the relationship between the read out credit amount C and the BET numbers. In the case where it is judged that the value of the credit amount C is less than the value of the total bet amount in the previous game (step S12 NO), the CPU 106 cannot start the game, so that it finishes this routine without carrying out any processing. On the other hand, in the case where it is judged that the value of the credit amount C is greater than or equal to the value of the total bet amount in the previous game (step S12 YES), the CPU 106 subtracts the value of the total bet amount in the previous game from the value of the credit amount C, and stores this subtracted value into a prescribed memory region of the RAM 110. After that, the CPU 106 shifts the processing to the step When it is shifted to the step S5, the CPU 106 carries out the combination determination processing. More specific processing content of this combination determination processing is as follows.

In the combination determination processing, first, the CPU 106 determines a combination of symbols to be stopped along the above described payline. More specifically, the CPU 106 issues a command for generating a random number to the random number generator 112,

O

and extracts a random number in a prescribed range to "65535" 00 in the present embodiment) generated by the random number generator 112. The CPU 106 stores this extracted random number into a prescribed memory region of the RAM 110. In the present embodiment, the random 00 number is generated by the random number generator 112 that is provided CI at external of the CPU 106, but it is also possible to generate it Sby the calculation processing of the CPU 106, without providing this C 10 random number generator 112. The CPU 106 reads out the basic game random number table (see Fig. 13) and a table of specific combination for awarding a prize (not shown) stored in the ROM 108, and stores the read out basic game random number table and the table of specific combination for awarding a prize into a prescribed memory region of the RAM 110. The CPU 106 controls the stopping display of each reel according to the above described basic game random number table. The CPU 106 reads out the basic game random number table and the table of specific combination for awarding a prize stored in a prescribed memory region of the RAM 110, and refers to the basic game random number table by using the random number written in a prescribed memory region of the RAM 110 as a parameter, and thereby determines a combination of symbols to be stopped regarding the above described payline. When the specific combination for awarding a prize is determined in this way, the CPU 106 stores this determined specific combination for awarding a prize into a prescribed memory region of the RAM 110. The CPU 106 reads out the random number value and the specific combination for awarding a prize written in a prescribed memory region of the RAM 110, and determined a combination of symbols to be stopped according to the read out random number value and the specific combination for awarding a prize. At this point, a symbol arrangement table (not shown) stored in the ROM 108 is read out by the CPU 106 and stored into a C-i prescribed memory region of the RAM 110 as well as referred. The CPU O 106 stores the determined symbols to be stopped data into a prescribed C memory region of the RAM 110. Alternatively, it is possible to determine 00 O the symbols to be stopped for each reel by using the above described basic game random number table.

When the combination of symbols to be stopped regarding the above 00 described payline is determined, the CPU 106 judges whether the c-i combination of symbols to be stopped regarding the payline is the specific combination for awarding a prize or not. Then, in the case where the combination of symbols to be stopped regarding the above described payline is the specific combination for awarding a prize, the CPU 106 sets a flag indicating that a prize is to be awarded active, for that specific combination for awarding a prize, in order to generate a prize corresponding to the combination of symbols which is the above described specific combination for awarding a prize. This flag indicating that a prize is to be awarded that is set active is stored into a prescribed memory region of the RAM 110 by the CPU 106. On the other hand, in the case where the combination of symbols to be stopped regarding the payline is the other combination, that is the combination for a lost game, the CPU 106 does not set the above described flag indicating that a prize is to be awarded active. After that, the CPU 106 shifts the processing to the step S6.

In the subsequent step S6, the CPU 106 starts the rotation of the mechanical reels 3A to 3E. More specifically, the CPU 106 rotates the mechanical reels 3A to 3E sequentially or simultaneously, according to the symbol arrangement table stored in the RAM 110.

After starting the rotation of the mechanical reels 3A to 3E, the CPU 106 counts the number of driving pulses transmitted to each one of the stepping motors 45A to 45E, and stores the count value into a prescribed memory region of the RAM 110. Every time the mechanical reels 3A to 3E are rotated, reset pulses are acquired, and these reset pulses of the mechanical reels 3A to 3E are inputted into the CPU 106 through the reel position detection circuit 46. By the reset pulses

O

so obtained, the driving pulse count values written in the RAM 110 00 are cleared to In this way, the count values corresponding to the rotation positions in a range of one rotation for the mechanical reels 3A to 3E are stored in a prescribed region of the RAM 110. In 00 the symbol arrangement table stored in the RAM 110, the rotation position of each of the mechanical reels 3A to 3E and the symbols of Seach of the mechanical reels 3A to 3E are set in correspondence. At 1C 0 a time of referring to the symbol arrangement table, the CPU 106 sets in correspondence the code numbers sequentially assigned to each constant rotation pitch of the mechanical reels 3A to 3E and the symbols codes indicating symbols provided in correspondence to these code numbers, with reference to the rotation positions at which the above described reset pulses occur.

When the rotation of the mechanical reels 3A to 3E is started, the CPU 106 waits for a prescribed time to elapse (step S7). At a timing where a prescribed time has elapsed (step S7 YES), the CPU 106 automatically stops the rotation of the mechanical reels 3A to 3E (step S8) More specifically, the CPU 106 stops the rotation of the mechanical reels 3A to 3E sequentially or simultaneously, such that the combination of stopped symbols corresponding to the specific combination for awarding a prize, that is determined at the step according to the specific combination for awarding a prize that is written in a prescribed memory region of the RAM 110, will be displayed in the display region that has an interactive relationship with the player visually. After that, the CPU 106 shifts the processing to the step S9.

When it is shifted to the step S9, the CPU 106 judges whether a prescribed symbol combination is realized by the combination determination processing at the step S5 or not. More specifically, C-i the CPU 106 judges according to a state of the flag indicating that O a prize regarding the payline is to be awarded which is stored in a C prescribed memory region of the RAM 110. In the case where the flag 00 O indicating that a prize is to be awarded is not set active, that is, in the case where the specific combination for awarding a prize is "others" (step S9 NO), the CPU 106 judges that the specific combination 00 for awarding a prize is not realized, and finishes this routine. On c-i the other hand, in the case where the flag indicating that a prize Sis to be awarded is set active, that is, in the case where the specific combination for awarding a prize is other than the above described "others" (step S9 YES), the CPU 106 shifts the processing to the step When the processing is shifted to step S10, the CPU 106 judges whether or not the specific combination for awarding a prize is "BONUS." Specifically, "BONUS" means that "BONUS" symbols are aligned along a payline as shown in Fig. 20, as described later. In this embodiment, when the "BONUS" combination is made, the second game is started. The CPU 106 makes a judgment on the basis of the data on the specific combination for awarding a prize. The data on the specific combination is stored in a predetermined memory region of the RAM 110. If the data on the specific combination for awarding a prize does not indicate a "BONUS" combination (step S10: NO), the CPU 106 judges that the "BONUS" combination is not made as the specific combination for awarding a prize, and shifts the processing to step S13. On the other hand, if the specific combination for awarding a prize indicates a "BONUS" combination (step S10: YES), the CPU 106 judges that the "BONUS" combination is made as the specific combination for awarding a prize, and shifts the processing to step Sil.

When the processing is shifted to step Si, the CPU 106 performs the second game processing shown in Figs. 20A to 20C, which will be described later. Specifically, the CPU 106 transmits a second game starting signal to the center controller 14. After performing the S second game processing, the CPU 106 terminates this routine.

O On the other hand, when it is shifted to the step S13, the CPU 106

00 pays out the number of coins according to the above described specific combination for awarding a prize. More specifically, the CPU 106 calculates the payout amount of coins corresponding to the above 00 described specific combination for awarding a prize by referring to CI the basic game payout table. The CPU 106 reads out the credit amount Sstored in a prescribed memory region of the RAM 110, adds the above 1C 0 described calculated payout amount to this read out credit amount, and stores this added value in a prescribed region of the RAM 110.

The CPU 106 displays that stored value on the credit amount display unit 49. After that, the CPU 106 finishes this routine.

Next, using Figs. 20A to 20C, the flow of processing operation of the game system 10 in the second game will be described. In the game system 10, the center controller 14 performs the processing of changing the payout of the second game to be executed on the slot machine 13 according to a bet made using the second game terminal The second game processing program of the slot machine 13 to be executed by the controller 100 containing the CPU 106 of the main slot machine 13, the second game processing program of the center controller 14 to be executed by the controller 200 containing the CPU 206 of the center controller 14, the second game processing program of the slot machine 13 to be executed by the controller 100 containing the CPU 106 of the slot machine 13, and the second game processing program of the second game terminal 15 to be executed by the controller 300 containing the CPU 306 of the second game terminal 15 will be described one by one.

The programs shown in the flow chart of Fig. 20A to Fig. 20C are stored in the ROM 108 and the RAM 110 provided in the slot machine 13, the ROM 208 and the RAM 210 provided in the center controller 14, or the ROM 308 and the RAM 310 provided in the second game terminal o 15. Then, the control operations according to the programs are executed O by the controller 100 containing the CPU 106 of the slot machine 13,

O

00 the controller 200 containing the CPU 206 of the center controller 14, or the controller 300 containing the CPU 306 of the second game terminal 15. In the following description, the CPU of each controller 00 will be described as the subject of the controlling.

First, the second game processing program for the slot machine 13 Swill be described by referring to Figs. 20A to 20C. In step S101 of 1C 0 Fig. 20A, the CPU 106 transmits a second game starting signal to the center controller 14. Then, the CPU 106 shifts the processing to step S102. The second game starting signal contains at least data for identifying the slot machine 13 and information on the credit amount bet and the payline at the time when the "BONUS" combination is made in the basic game.

In step S102, the CPU 106 causes the liquid crystal display 30 of the slot machine 13 to display the BET screen 70 shown in Fig. 19, which will be described later (step S102). Then, the CPU 106 starts a waiting period (betting operation accepting period) as a betting period in which the player can bet chips (step S103). During this betting period in which bets can be accepted, a player can bet his or her chips on the BET areas 73 relating to numbers predicted by himself or herself, by operating the touch panel 32. Betting places and the number of bets vary according to the credit amount bet and the payline in the basic game on the slot machine 13 as shown in the second game payout table (see Fig. 15). As to a method of controlling this, the following may be adopted: after the CPU 106 of the slot machine 13 transmits the betting information, the CPU 206 of the center controller 14 performs the control; or alternatively, the CPU 106 transmits the second game starting signal in step S101, a condition for allowing bets is received as data from the center controller 14, the data is stored on the RAM 110 of the slot machine 13, and then the CPU 106 t of the slot machine 13 performs the control by using the data. A specific method of making bets using the BET screen 70 will be described 00 O by referring to Fig. 19 described later.

Thereafter, the CPU 106 judges whether or not a BET operation has been performed on the second game through the touch panel 32 (step 00 S104) If the CPU 106 judges that a BET operation has been performed, the CPU 106 transmits a BET signal to the center controller 14 (step S105). This BET signal contains the betting information (information indicating the specified BET area 73, the number of chips bet on the specified BET area 73 (a bet amount), and the like) on a bet made by the player using the slot machine 13.

Upon receiving, from the center controller 14, a signal (hereinafter referred to as a BET status signal) regarding information indicating the BET status of the other players, the CPU 106 selects a second game payout table (step S106) according to a command to specify the second game payout table which the center controller 14 judges by depending on the BET status of the other players, the status of BETs made on the second game using the second game terminals (or the joining slot machine 13 in some cases). Then, the CPU 106 announces to the player that a betting condition is changed (step S107).

The CPU 106 judges whether or not a BET operation has been performed on the second game through the touch panel 32 (step Sl08). If the CPU 106 judges that a BET operation has been performed, the CPU 106 transmits a BET signal to the center controller 14 (step S109).

The CPU 106 causes the liquid crystal display 30 to display the BET status (see Fig. 21) of the other players, which has been received from the center controller 14 (step S110).

The CPU 106 judges whether or not a command to stop accepting BETs from the other players has been inputted (step Sill). If the CPU 106 judges that the command has been inputted, the CPU 106 transmits a command signal to the center controller 14 (step S112).

o Then, the CPU 106 judges whether or not a betting period end signal has been received from the center controller 14 (step S113). If the 00 O CPU 106 judges that a betting period end signal has not been received, the CPU 106 shifts the processing back to step S104, and repeatedly executes the processing from step S104 to step S112 until a betting 00 period end signal is received.

(N

If the CPU 106 judges that a betting period end signal has been received in step S113, the CPU 106 stops accepting the betting operations (step S114). Thereafter, the CPU 106 pays out credits based on a credit payout result received from the center controller 14 (step S115). Specifically, data on an amount of credits which corresponds to the payout of the roulette game is recorded in the RAM 110. After that, the processing is shifted to step S116.

In step S116, the CPU 106 judges whether or not to finish the second game. Specifically, if there is still a credit for the roulette game, the CPU 106 causes the liquid crystal display 30 to display a small window 85 such as shown in Fig. 25, which will be described later.

Thus, the CPU 106 lets the player make a selection, and judges whether or not to finish the second game according to the player's selection.

On the other hand, if no credit is left for the roulette game, the player has no choice, and the CPU 106 finishes the second game. If no credit is left for the roulette game, or if the player chooses to finish the roulette game (in the case where it is judged as YES in the processing of step S116), the CPU 106 shifts the processing to step S117. On the other hand, if there is still a credit for the roulette game and the player chooses to continue the roulette game (in the case where it is judged as NO in the processing of step S116), the CPU 106 shifts the processing to step S101. Furthermore, the CPU 106 transmits a second game starting signal to the center controller 14 again, whereby a new betting period is started again. Thus, the processing goes to the next game.

o At the step S117, the CPU 106 transmits the second game finishing C signal to the center controller 14. Then, in the case where the credit 00 O in the roulette game is remaining, the CPU 106 reads out the credit amount stored in a prescribed memory region to be used in the basic game, and adds the credit data according to the payout of the roulette 00 game stored in the RAM 110 to this read out credit amount. Then, this Cl added value is stored into a prescribed memory region of the RAM 110, Sand displayed on the credit amount display unit 49 of the slot machine 13. After that, the CPU 106 finishes this routine. In the case where the second game is to be finished at the slot machine 13, that roulette game processing is finished.

Next, the second game processing program of the center controller 14 will be described with references to Fig. 20A to Fig. Upon receipt of the second game starting signal transmitted from the CPU 106 of the slot machine 13 in step S101, the CPU 206 transmits a second game starting signal to all the second game terminals 15 (step S201). In addition, the CPU 206 causes the movable floors 18 to be elevated. Each of the movable floors 18 is fixedly provided with the slot machine 13 that has transmitted the second game starting signal and the chair. Furthermore, the CPU 206 causes the large scale monitor 16 to display the fact that the second game is going to start, as shown in Fig. 18, which will be described later. With the elevation of the movable floors 18 of the slot machines 13 and the display of the second game starting message on the large scale monitor 16 as described above, not only players of other slot machines 13 but also third persons in the gaming facility arcade can know that the second game is going to start. Thereafter, the CPU 206 shifts the processing to step S202.

In step S202, the CPU 206 starts measuring a waiting period from the time when the slot machine 13 transmits the second game starting signal. The waiting period is an accepting period when players can O make bets. During this waiting period, players of the slot machines 13 who join the game can bet their chips on the BET areas 73 relating O to numbers that they predict as winning numbers, by performing an 00 operation using the touch panels 32 of the liquid crystal displays 30. Moreover, players of the second game terminals 15 (or players of other slot machines 13), which will be described later, can bet on 00 the winning or losing of the players of the second game (players of (1 the slot machines 13).

SAfter step S202, upon receipt of a BET signal (a signal indicating 1 0 the content of a BET on a player of the second game) from each of the second game terminals 15, the CPU 206 stores information on the bets on the player of the second game on the basis of the signal, and transmits a BET status signal indicating the information to the slot machine 13 (step S203).

In this embodiment, the second game payout table to be used in the second game on the slot machine 13 is selected according to a BET status (step S106). The BET status indicates, for example, the number of joining players betting on the player who wins for the second game, and the bet amount of each joining player, in the joining game executed mainly on the second game terminals After that, upon receiving, from the slot machine 13, a command signal based on a command to stop accepting BETs from the other players, the CPU 206 transmits a betting period end signal to all the second game terminals 15 (step S204). Next, the CPU 206 judges whether or not the remaining waiting period is five seconds. It should be noted that the BET time display unit 74 also displays the remaining waiting period on the BET screen 70 of the second game device 11 (see Fig.

If the CPU 206 judges that the remaining waiting period is five seconds, the CPU 206 causes the ball 65 to be thrown into the roulette wheel. Specifically, the ball throwing device is first driven to throw the ball 65 into the roulette wheel, whereby a number determination processing is executed by the roulette device 60 according to a game S execution program. More specifically, after the ball 65 is thrown in, O the CPU 206 further drives the driving motor to rotate the wheel 62

O

00 at a predetermined rotational speed in a direction opposite to the ball throwing direction. The thrown ball 65 rolls over the roulette wheel along the guide wall 66. Then, as the rotational speed decreases 00 and the centrifugal force reduces, the ball 65 rolls down the slope CI of the frame body 61 toward inside, and reaches the rotating wheel 62 (see Fig. 9) 1 0 Then, the ball 65 that rolled to the wheel 62 is accommodated into any one of the number pockets 63 by passing over the number display plates 64 on the outer side of the rotating wheel 62, and the number (any one of "00" and to "36" shown in Fig. 7) described in the number display plate 64 corresponding to the number pocket 63 that accommodated the ball 65 becomes the winning number.

In addition, the CPU 206 takes the image of the roulette device by the viewpoint movable camera 17 in response to the entering of the ball 65 inside the roulette wheel, and displays it on the monitor 16. In this way, the player can watch the manner by which the winning number is determined in the roulette game by watching the monitor 16, without looking into the second game device 11. The monitor 16 may have its screen divided according to the need and display both the roulette device 60 and the BET screen Thereafter, the CPU 206 judges whether or not the waiting period ends (step S207). Then, if the CPU 206 judges that the waiting period does not end, the processing is shifted back to a point before step S203. On the other hand, if the CPU 206 judges that the waiting period ends, the CPU 206 transmits a betting period end signal indicating that the waiting period ends, to the CPUs 106 of the slot machines 13 and the CPUs 306 of the second game terminals 15 (step S208).

Next, the CPU 206 accumulates the credit corresponding to 0.5% of the total credit bet by the slot machines 13 and the second game o terminals 15 that is received at the step S208, onto the amount of C JP recorded in the JP accumulation memory area of the RAM 210 (step 00 S209). Then, in conjunction with that, the display of the JP display unit 75 is updated.

At the step S210, the CPU 206 judges that the ball 65 is accommodated 00 into the number pocket 63, and after that, activates the win judgment (Ni device, to judge which number pocket 63 set in correspondence to which Snumber has accommodated the ball 65. After that, the CPU shifts the 1C 0 processing to the step S211.

In step S211, the CPU 206 judges whether or not each of the chips bet from the slot machines 13 wins, on the basis of the number of the pocket judged as the one accommodating the ball 65 in step S210, and the betting information on the slot machines 13. Moreover, in step S211, the CPU 206 judges whether or not each of the players operating the second game terminals 15 wins, on the basis of the winning or losing of the players playing the second game using the slot machines 13 and the betting information on the second game terminals 15. After that, the CPU 206 shifts the processing to step S212.

In step S212, the CPU 206 executes a payout determination processing.

In the payout determination processing, the CPU 206 determines the payout of the roulette game and the payout of the game (the joining game) in which bets are made on the players of the roulette game.

The payout of the roulette game is determined as follows.

Specifically, the CPU 206 recognizes winning chips bet on the winning number for each slot machine 13, and calculates the sum of credit payout amounts paid to the slot machine 13 using the payout rate (a credit amount paid per chip (bet)) for each BET area 73 in the second game payout table stored in the payout credit memory area of the ROM 208.

Thus, the payout amount of the roulette game (the second game) is determined.

On the other hand, the payout of the joining game is determined O as follows. Precisely, the CPU 206 calculates the sum of bets made on each player of the roulette game. Then, the bets on each player 00 O of the roulette game are determined.

For example, in the case where all the joining players who have bet on one player of the roulette game win, the bet amount of each 00 joining player multiplied by a predetermined rate is paid back to the Cl joining player. By contrast, in the case where all the joining players Swho have bet on one player of the roulette game lose, the bets on the player are collected for the casino's profit.

In the case where some of the joining players who have bet on one player of the roulette game win and the rest of them lose, a part of the bets on the player of the roulette game is collected for the casino's profit. The rest of the bets is divided according to the bet amounts of the winning joining players, and then is distributed to the winning joining players. Moreover, the monitor 16 displays information on the winning number, the number of winners and the like.

Next, the CPU 206 executes the processing of transmitting the credit payout results of the roulette game based on the payout determination processing in step S212. Specifically, the CPU 206 outputs credit data corresponding to the payout amounts to the winning slot machines 13 and the winning second game terminals 15. After that, the CPU 206 shifts the processing to step S214.

In step S214, the CPU 206 drives the ball collecting device provided under the wheel 62 to collect the ball 65 on the wheel 62. The collected ball 65 is to be thrown into the wheel 62 of the roulette device again in subsequent games. Thereafter, upon receipt of a second game finishing signal from the slot machine 13, the CPU 206 lowers the movable floor 18, and terminates this routine.

Finally, the second game processing programs of the second game terminal 15 will be described with references to Fig. 20A to Fig. At the step S301 of Fig. 20A, the CPU 306 of the second game terminal o 15 receives the second game starting signal transmitted from the center O controller 14.

O

00 O In response to this second game starting signal, the CPU 306 of the second game terminal 15 causes the BET screen 70 (see Fig. 24), which will be described later, to be displayed on the display 93 (step 00 S301), and causes a waiting period to start as a betting period in CI which a bet can be made on a player of the second game (step S302).

During this betting period in which the bet can be accepted, the player can bet on the winning or losing of a player of the second game, by performing an operation using the touch panel 99.

After that, the CPU 306 judges whether or not a BET operation has been performed on the winning or losing of a player of the second game through the touch panel 99 (step S303). If the CPU 306 judges that the BET operation has been performed, the CPU 306 transmits a BET signal to the center controller 14 (step S304). This BET signal contains betting information on a bet made by the player using the second game terminal 15 (information indicating a game result (winning or losing) of a designated player, the amount of bet credits, and the like).

Then, the second game terminal 15 judges whether or not a betting period end signal has been received (step S305). If the second game terminal 15 judges that a betting period end signal has not been received, the second game terminal 15 shifts the processing back to step S303, and repeatedly executes the processing from step S303 to step S304 until a betting period end signal is received. It should be noted that the betting period end signal is transmitted to the second game terminal 15 in any of the following cases and (II): in response to a command signal transmitted by the slot machine 13 (step S112) when a command to stop accepting BETs from the other players is inputted to the slot machine 13, the center controller 14 transmits a betting period end signal to the second game terminal (step S204); and (II) the second game terminal 15 receives the betting period end 0 signal transmitted by the center controller 14 (step S208) when the 00 center controller 14 judges that the waiting period ends.

In the case of the above-described condition in the slot machine 13, the waiting period does not end until the slot machine 13 receives 00 the betting period end signal (step 3208) transmitted from the center Cl controller 14, even though the waiting period has ended in the second Sgame terminal 15. On the other hand, in the case of the condition (II), 1C 0 the waiting period is simultaneously terminated in the slot machine 13 and the second game terminal If the second game terminal 15 judges in step S305 that the second game terminal 15 has received a betting period end signal, the second game terminal 15 stops accepting a betting operation (step S306).

After that, the CPU 306 of the second game terminal 15 pays out credits based on a credit-payout result received from the center controller 14 (step S307).

The above-described operations in the second game executed on the slot machine 13 of this embodiment will be specifically described using exemplary displays of the respective screens displayed on the liquid crystal display 30 during the game.

Figs. 21 and 22 show exemplary displays in the basic game on the slot machine 13 of the embodiment of the present invention. The symbols are stopped and displayed on the liquid crystal display 30 of the slot machine 13.

In the case of this example, the "BONUS" symbols are aligned horizontally in a central portion, and the "BONUS" combination is made on payline L5. As described previously, in the case where the "BONUS" combination has been made, a transition to the second game is made.

Accordingly, a small window 81A containing a phrase, "Congratulations! Let's start the roulette game" is displayed on the liquid crystal display 30 as shown in Fig. 22.

Fig. 23 shows an exemplary display of a display for urging to join C the second game to be displayed on the large scale monitor 16. By 00 displaying "Let's join the roulette game!" on the large scale monitor 16 in this way, the third persons in the gaming facility who can use the second game terminals 15 can join the roulette game. By outputting 00 sounds from the speakers provided on left and right of the large scale (Ni monitor 16 as shown in Fig. 2, the announcement to the third persons Scan be made more effectively.

1C 0 Fig. 24 shows an exemplary display of the second game in the slot machine 13. More specifically, it shows an exemplary display to be displayed on the liquid crystal display 30 at a time of making the betting operation of the roulette game. The similar display is presented also on the display 93 of the second game terminal 15. Except for those explained in Fig. 9 described above, this display will be described with reference to Fig. 24.

First, this BET screen 70 is displayed on the liquid crystal display of the slot machine 13 and the display 93 of the second game terminal Here, it will be described as displayed on the liquid crystal display 30 of the slot machine 13. On the lower side of the betting board 71 displayed on the BET screen 70, a result log display unit 72, unit BET buttons 77, a payout amount display unit 78 and a credit amount display unit 79 are displayed sequentially from a upper left side of the screen. The payout amount display unit 78 and the credit amount display unit 79 are displaying those in the roulette game, unlike the payout amount display unit 48 and the credit amount display unit 49 of the slot machine 13.

The unit BET buttons 77 are buttons for betting chips on the BET area 73 (on a grid of a number and a mark or on a line forming a grid) specified by the player. The unit BET buttons 77 comprises four types of a 1-BET button 77A, 5-BET button 77B, 10-BET button 770 and 100-BET 61 button 77D.

o The player specifies an area to bet by displaying a cursor 80 to o be described below, by directly pressing the BET area 73 to be bet 00 on a screen by a finger or the like first. In that state, when the 1-BET button 77A is pressed, the player can bet chips in unit of one chip (the number of bet chips will be increased sequentially like 1, 00 2, 3 and so on whenever the 1-BET button 77A is pressed by the finger (1 or the like). When the 5-BET button 77B is pressed, the player can bet chips in unit of five chips (the number of bet chips will be increased 1C 0 sequentially like 5, 10, 15 and so on whenever the 5-BET button 77B is pressed by the finger or the like). When the 10-BET button 77C is pressed, the player can bet chips in unit of ten chips (the number of bet chips will be increased sequentially like 10, 20, 30 and so on whenever the 10-BET button 77C is pressed by the finger or the like) When the 100-BET button 77D is pressed, the player can bet chips in unit of one hundred chips (the number of bet chips will be increased sequentially like 100, 200, 300 and so on whenever the 100-BET button 77D is pressed by the finger or the like).

Consequently, even at a time of betting many chips, its operation can be simplified. One coin to be used in the basic game of the slot machine 13 corresponds to one chip to be used in the second game.

The places to bet chips are not limited to one place. After pressing the unit BET button, by enabling the player to specify another BET area 73, it becomes possible to make the betting operations for a plurality of places.

The payout amount display unit 78 displays the number of bet chips of the player in the previous game, and the payout credit amount. Here, the number obtained by subtracting the number of bet chips from the payout credit amount is the credit amount newly obtained by the player in the previous game. In this exemplary display, it is the first game since a transition to the second game is made by the slot machine 13 62 so that the number of bet chips and the payout credit amount are both 0 In addition, the credit amount display unit 79 displays the credit 00 amount currently owned by the player. This credit amount is decreased according to the number of bet chips when the chips are bet (one credit for one bet chip). When the bet chips become win and the payout of 00 credit is made, the credit amount will be increases as much as the CI number of payout chips. When the credit amount owned by the player Sbecomes it becomes game over. In this exemplary display, the case where a transition to the second game is made when the credit amount at the slot machine 13 is is shown. Namely, 20 chips are bet on "2tol" which covers "10" and so on, and 1 chip is bet on four numbers and so that "79" obtained by subtracting "21 (20+1) from the number of chips "100" at a time of the transition is displayed as the credit amount.

On the betting board 71, the cursor 80 for indicating the BET area 73 currently selected by the player is displayed.

When the player makes the bet on the BET screen 70 in a configuration described above, first the BET area 73 (on a grid of a number and a mark, or a line forming a grid) to be bet is specified on a screen by directly pressing it by the finger. As a result, the cursor 80 moves to the specified BET area 73.

After that, by pressing each unit button (1-BET button 77a, button 77B, 10-BET button 77C, 100-BET button 77D) of the unit BET buttons 77, the chips in that unit number are bet on the specified BET area 73. For example, by pressing the 10-BET buttons 77C four times, the 5-BET button 77B once, and 1-BET button 77A three times, a total 48 chips can be bet. The player can make the betting operation by operating a terminal at hand using these functions.

In this embodiment, there is a case where a BET status is transmitted from the center controller 14, and a BET condition is changed accordingly (step S106 of Fig. 20B) while the player is performing o a BET operation on this BET screen 70. In this case, for the remaining C time displayed in the BET time display unit 74, a display for announcing 00 to the player that a BET condition is changed, for example, is made on the BET screen Figs. 25 and 26 show exemplary displays of screens displayed on 00 the liquid crystal display 30 after the aforementioned payout CI processing in step S115. Of these, Fig. 25 is an exemplary display Sof a screen displayed on the liquid crystal display 30 of the slot 1 0 machine in the case where there is still a credit for the roulette game. In this case, a small window 84A for asking the player whether or not to continue the game is displayed in the center of the screen.

In addition, a countdown number 85 is displayed in an upper right portion of the window. The countdown number 85 is sequentially counted down from and so on. In the case where the player does not press, via the touch panel 32 (see Fig. either the YES button 82 or the NO button 83 located in a lower portion of the window 84A before the countdown number 85 becomes or in the case where the NO button 83 is pressed during the countdown, it is judged that the roulette game is to be finished. Then, a small window 84B indicating that the game is over is displayed such as shown in Fig. 26. On the other hand, in the case where no credit is left for the roulette game, the window in Fig. 26 is displayed on the liquid crystal display without displaying the window in Fig. 25, and the roulette game is finished.

In this way, in the game system and the playing method according to the present embodiment, when the basic game is played by the slot machine 13 and the combination of prescribed symbols such as "BONUS" is stopped on the payline L5, for example, the roulette game to be played by the second game device 11 is started. In this case, the slot machine 13 becomes a terminal capable of making the betting operation O of the roulette game. Furthermore, in the roulette game, the player o can use credits awarded for the combination of "BONUS" symbols in the o basic game. The roulette game is finished mostly when the player 00 desires to finish playing or runs out of credit to bet. Between these events, the payout of the second game on the slot machine 13 is changed according to bets made using the second game terminals 15 which 00 similarly become capable of executing an operation for betting on the (1 roulette game, which is the second game. Consequently, a player can Splay the roulette game many times in some playing methods which the 1 0 player chooses.

On the slot machine 13 or the second game terminal 15 on which a third person is playing, a game can be executed in which the third person bets on the winning or losing of a bet made by the player of the slot machine 13, who is a main player.

Fig. 27 shows an exemplary display of a screen to be displayed on the liquid crystal display 30. The upper half of Fig. 27 is displaying a manner by which an airplane 86 is flying from an upper right side on the liquid crystal display 30 of the slot machine 13 which is playing the basic game. By the effect of the airplane 86, it is possible to arouse expectation to the event to take place from now on in the player.
