Symbols are scrolled in each of the columns of the Sdisplay areas qll to q33 when the slot game is started on each of the areas Al to C< Five LEDs 53a to 53e are provided on the left side of the display areas qll to q33 of each of the areas Al to A10. The CI LEDs 53a to 53e notify the activated payline(s) on each of the 8 areas Al to A10. As shown in Fig. 13, five paylines are prepared Oo on the display areas qll to q33. A horizontal line in the middle 0 row is LI, a horizontal line in the upper row is L2, a horizontal line in the lower row is L3, a diagonal line going down to the right is L4, and a diagonal line going up to the right is The LEDs 53a to 53e light up according to a bet amount.

In detail, only the LED 53a lights up when one credit is bet.

The LEDs 53b and 53c, in addition to the LED 53a, light up when two credits are bet. The LEDs 53d and 53e, in addition to the LEDs 53a to 53c, light up when three credits are bet.

It is indicated that the line LI has been activated, when the LED 53a lights up. In addition, it is indicated that the lines L2, L3 have been activated, respectively, when the LEDs 53b, 53c light up. Furthermore, it is indicated that the lines L4, L5 have been activated, respectively, when the LEDs 53d, 53e light up.

Only the line LI is activated when one credit has been bet, the lines LI, L2, and L3 are activated when two credits have been bet, and all of the lines LI to L5 are activated when three credits have been bet. Then, a payout is awarded according to a winning combination(s) when the winning combination(s) is achieved on the activated payline(s).

An activation indicating frame 51 is provided on each peripheral edge of the areas Al to A10, as shown in Fig. 12.

00 O Each of the activation indicating frames 51 lights up on the LCD 16 for the activated areas Al to A10. The activation indicating frame 51 lights up on each of the areas Al to CI on which at least one credit is bet. It is possible for a player to easily recognize the activated slot game area(s) by the CI activation indicating frame(s) 51.

SA bonus game indicator 52 is provided above each of the 00 areas Al to A10, as shown in Fig. 12. The bonus game indicator 00 52 of each of the areas Al to A10 lights up on the LCD 16 during a bonus game. It is possible for a player to easily recognize the slot game area(s) during the bonus game by the bonus game indicator(s) 52.

Fig. 14 shows winning combinations in the slot game. As shown in Fig. 14, the bonus game is triggered on the own slot game area when three 7's are rearranged on the activated payline.

For example, the bonus game is started when three 7's has been rearranged on the activated payline L1 shown in Fig. 12. A payout is awarded to the player when three APPLEs are rearranged, a 10-credit payout is awarded when three BELLs are rearranged, and a 2-credit payout is awarded when a "CHERRY" is rearranged on the leftmost of the activated payline.

Hereinafter, a table shown in Fig. 14 will be referred to as a payout table.

Next, the operation of the slot machine 10 of the present embodiment will be described with reference to the flow charts shown in Figs. 4 to 11. Fig. 4 is a flow chart illustrating the procedure of the processing of the slot game.

First, the CPU 106 (Fig. 3) accepts a bet amount when the processing of the present routine is started (step S101). A player places a bet (with a desired bet amount) by pressing the 00 bet switch 25. Alternatively, the player inserts a desired Snumber of medals into the medal insertion slot 21 to place a bet corresponding to the inserted medals. If a bet is placed C by pressing the bet switch 25, the CPU 106 subtracts the bet amount having been input from an internally stored credit amount Cl (step S102). For example, if the stored credit amount is Scredits and a 30-credit bet amount is received, the stored 00 credit amount will be 20 credits.

0O Subsequently, the CPU 106 determines the area(s) to be activated among the ten slot game areas Al to A10 (step S103) This processing will be described later in detail with reference to Fig. 8 and Fig. 9.

After area activation processing, the CPU 106 determines a payline(s) to be activated on the activated area(s) (step S104) The payline(s) to be activated is determined according to the bet amount, as described above. Specifically, the line L1 is activated when one credit is bet on each of the slot games on the areas Al to A10, the lines LI, L2, and L3 are activated when two credits are bet, and all of the lines L1 to L5 are activated when three credits are bet (see Fig. 13). The activation indicating frame(s) 51 of the area(s) Al to A10, on which a bet has been placed, lights up to indicate the activated area(s) to the player.

For example, when the areas Al to A6 has been activated, the activation indicating frames 51 of the activated areas Al to A6 are lit up, as shown in Fig. 15. On the contrary, the activation indicating frames 51 of the non-activated areas A7 to A10 are not lit up. Lit-up frames are drawn with hatchings and un-lit frames are drawn unpatterned in Fig. 00 Although a detailed description will be given later, it Sis also possible to place a bet randomly on each slot game on the areas Al to A10. For example, the areas Al, A3, A6, A8 and C-i A10 are activated randomly (a bet are placed on each of these areas randomly) and then their activation indicating frames 51 Ci are lit up, as shown in Fig. 17.

Furthermore, although a detailed description will be 0 given later, the activation indicating frame(s) 51 of the 0O activated area(s) are blinked when the number of the bonus games T reaches or exceeds a predetermined number.

After step S14 in Fig. 4, the CPU 106 determines whether or not the start switch 27 has been pressed (step S105). The slot game is executed on each of the activated area(s) if it is determined that the start switch 27 has been pressed (step Sl06).

Next, a processing procedure of the slot game executed on each of the activated areas Al to A10 is described with reference to Fig. 5. A slot game in an activated slot game area Al is described as an example.

First, the CPU 106 determines whether a bonus flag of the area Al is or (step 3201). The default value of the bonus flag is and set to when the bonus game is to be executed.

The CPU 106 determines symbols to be stopped (hereinafter, simply referred to as stop symbols) in each of the display areas qll to q33 on the area Al when the bonus flag is (step S203).

By this processing, symbols "BELL", "APPLE", etc.) to be displayed in each of the display areas qll to q33 are determined.

Next, the CPU 106 scrolls symbols in the display areas qll to q33 of the area Al (step 3204). Then, the symbols stop 00 in each of the display areas qll to q33 after a predetermined cqtime has elapsed. The displayed symbols at this time are the stop symbols determined in step S203.

c- Then, the CPU 106 determines whether or not a bonus trigger combination (three 7's: Fig. 14) is rearranged on any of the c' activated paylines (step S205) For example, it is determined whether or not the bonus trigger combination is achieved on any c' of the paylines L1 to L5 (Fig. 13) when all of the lines L1 to 00 are activated.

Then, the CPU 106 executes bonus game starting processing (step S206) when the bonus trigger combination is achieved on any of the paylines L1 to L5. The bonus game starting processing will be described later.

On the other hand, the CPU 106 determines whether or not one of winning combinations has been achieved on any of the activated paylines (step S207) when the bonus trigger combination has not been achieved. A payout is awarded according to a winning combination (step S208) when the winning combination has been achieved. On the other hand, the CPU 106 does not award a payout when a winning combination has not been achieved. And then the CPU 16 ends the slot game on the area Al. It may be possible to cash-out a medal(s) equivalent to a payout amount through the cash-out chute 28 or to add a credit(s) equivalent to a payout amount to the internally stored credits, when a payout is to be awarded.

Next, the bonus game starting processing is described with reference to the flowchart in Fig. 6.

The bonus flag is set to (step S301) when the bonus trigger is achieved in step S205 in Fig. 5. At this time, the bonus game indicator 52 (Fig. 12) lights up to notify the player 00 that the bonus game is being executed on the area Al. For example, the bonus game indicator 52 of the area A6 lights up to notify the player that the bonus game is being executed on Ci the area A6 as shown in Fig. 16.

Then, the CPU 106 determines the number of the bonus games C' T (step S302) The number of games T is, for example, fifty.

The number of games T may be fixed or determined each time 00 randomly by the CPU 106. The number of games T is stored in 0O the RAM 110.

Next, a payout for the bonus trigger is awarded (step S303).

For example, a 15-credit (15-medals) payout is awarded in the present embodiment. Then, the present processing is ended.

Bonus game execution processing is executed (step S202) for the next slot game on the area Al after step 201 in Fig.

5, when the bonus flag has been set to in the bonus game start processing (step S301 in Fig. 6).

The bonus game execution processing is described below with reference to the flowchart in Fig. 7. The CPU 106 executes processing for determining stop symbols (step S401) when the bonus game execution is started. This processing is the same processing as that in step S203 in Fig. 5. In step S401, three 7's are not rearranged on the payline, but the stop symbols are determined so that a winning combination is achieved with a high probability. In other words, a winning combination (three BELLs, three APPLEs or at least one CHERRY on the leftmost in Fig. 14) is achieved on an activated payline with higher probability in the bonus game than in the normal game.

Next, the CPU 106 scrolls the symbols in the display areas qll to q33 (step S402). This processing is the same as that in step S204 in Fig. 5. Then, the symbols stop in each of the 00 display areas qll to q33 after a predetermined time has elapsed.

SAt this time, the displayed symbols are the stop symbols determined in step S401.

C-I Next, the CPU 106 determines whether or not a winning combination has been achieved on the activated payline (step (I S403). A payout is awarded according to a winning combination S(step S404) when the winning combination has been achieved. On 0 the other hand, the CPU 106 does not award a payout when a winning 00 combination has not been achieved.

Then, the CPU 106 decrements the number of games T stored in the RAM 110 (step S405) Next, the CPU 106 determines whether or not the number of games T is (step S406). The bonus flag is reset to "0" when (step S407). In other words, the bonus flag is reset and the bonus game is ended when the predetermined number of bonus games has been expended.

Next, the area activation processing (step S103 in Fig.

4) is described with reference to a flowchart in Fig. 8 and a table in Fig. 18.

The CPU 106 first places a bet preferentially on the bonus slot game(s) (step S501) after the bet switch 25 has been pressed or a medal(s) has been inserted into the medal insertion slot 21. After that, a bet is placed sequentially on the slot game on the areas Al, A2, A3, in ascending order of the area numbers (step S502) For example, when the bonus game is being played on the area A8, the first to third credits are bet on the bonus slot game on the area A8 as shown in Fig. 18. Then the fourth credit is bet on the slot game on the area Al and the fifth credit is bet on the slot game on the area A2. Then, the above procedure 00 is repeated to place remaining first, second and third bets.

SIn this manner, thirty credits can be expended to place a -n 3-credit bet on each of the areas Al to A10, respectively.

C- Note that, a bet is placed preferentially on the bonus slot game on each of the areas when the bonus games are executed C-i simultaneously on two or more activated slot game areas. And Sthen, one bet is placed sequentially on the normal slot game on each of the areas.

00 Fig. 9 is a flowchart of another example of the area activation processing. In this processing, the CPU 106 first places a bet preferentially on the bonus slot game(s) on the areas (step S601) after the bet switch 25 has been pressed or a medal(s) has been inserted, as in the case shown in Fig. 8.

After that, a bet is placed sequentially on the slot game on the areas in random order (step S602). At this time, the bet order for the normal slot games is determined randomly by the CPU 106 at each game play.

Description of the operation of the slot machine 10 will be continued with reference to Fig. 4. The CPU 106 determines whether or not the internally stored credit amount has exceeded "100" (step S107) after the first execution of the slot game in step Sl06. In other words, the CPU 106 determines whether or not a continuous execution condition of the slot games is met. Although a threshold value is set to "100" in the present embodiment, any value may be set as the threshold value.

Alternatively, a player may also be allowed to set the threshold value.

An amount calculated by subtracting 100 from the internally stored credit amount is determined as a bet amount for an upcoming slot game (step Sl08) if it is determined in 00 step S107 that the internally stored credit amount has exceeded "100". For example, the bet amount is calculated such as 130 100 30 when the internally stored credit amount is "130".

C-i Subsequently, the CPU 106 determines the area to be activated among the slot game areas Al to A10 (step S109). This C-i processing is same as that in step S103. The CPU 106 determines the payline to be activated on the activated area (step S110) after the area determination processing. This processing is 00 same as that in step S104.

Subsequently, the CPU 106 determines whether or not the number of continuous execution of the games (hereinafter, referred to as "number of continuous games") Tn is equal to or larger than 50 (step Sill). In other words, the CPU 106 determines whether or not a condition for changing the payout rate is met. Although a threshold value is set to "50" in the present embodiment, any value may be set as the threshold value.

The number of continuous games Tn is stored in the RAM 110. The number of continuous games Tn is incremented by one for each execution of the game. The initial value of the number of continuous games Tn is The number of continuous games Tn is reset to the initial value when the continuous execution of the games is ended.

An effect displaying processing is executed (step S112) if the number of continuous games Tn is determined to be equal to or larger than 50 in step S109. In the effect displaying processing, the CPU 106 notifies the player that the number of continuous games Tn is equal to or larger than the threshold value Next, the procedure of the effect displaying processing will be described with reference to Fig. 10. The CPU 106 00 0 specifies the activated area determined in step S109 of Fig.

4 (step S701). And then, the CPU 106 blinks the activation c- indicating frame 51 of the specified area(s) (step S702) As C- a result, the player can recognize that the area(s) with the activation indicating frame(s) 51 blinked is activated and that C-i the number of continuous games Tn reaches (or exceeds) the threshold value. In the present embodiment, the payout rate is changed as described below when the number of continuous 00 games Tn reaches the predetermined threshold value. Therefore, the player can recognize that the payout rate has been changed when the activation indicating frame 51 has been blinked.

Description of the operation of the slot machine 10 will be continued with reference to Fig. 4. The CPU 106 executes a payout rate change processing in respect to the activated area(s) (step S113) after the effect displaying processing in step S112. In the payout rate change processing, the payout amounts of the payout table of Fig. 14 are doubled and set as new payout amounts. For example, the payout amount of three BELLs on the activated payline is usually 10, but it is doubled to 20 after changing. Here, a bonus game is started as usual by three 7's on the activated payline.

The CPU 106 increments the number of continuous games Tn stored in the RAM 110 to "Tn 1" (step S114) after the payout rate change processing in step S113. Note that, the processing flow proceeds to step S114 without executing the effect displaying processing and the payout rate change processing if the number of continuous games Tn does not reach 50 in step Sill.

Subsequently, the CPU 106 returns the processing back to step S106 and executes the slot game on the area(s) which was activated in step S109. Thus, the slot games are executed 00 continuously without determining whether or not the start Sswitch 27 is pressed if the processing flow returns from step S114 to step 5106.

C-i On the other hand, the CPU 106 executes a reset processing (step SI15) if it is determined in step S107 that the internally c- stored credit amount is equal to or smaller than "100". Here, blinking of the active area indicating frame(s) 51, change of the payout rate, and the number of continuous games Tn are all 00 reset. Specifically, the active area indicating frame(s) 51 is turned off. The payout rate is reset to normal shown in Fig.

14. The number of continuous games Tn is reset to the initial value The present processing is terminated (returned to step S101) after the reset processing.

Next, a game termination processing will be described with reference to the flow chart shown in Fig. 11. While the slot game execution processing of Fig. 4 is being executed, the CPU 106 continuously monitors whether or not the stop switch 31 is pressed (step S801). In other words, the CPU 106 continuously monitors whether or not a game terminating operation is detected. If it is determined that the game terminating operation is detected (step 5801: YES), the CPU 106 determines whether or not the slot game has already completed (step S802). In other words, the CPU 106 determines whether or not the slot game is being executed. If the slot game has not completed, processing of step S802 is repeated until the slot game has been completed. If it is determined that the slot game has already completed, the CPU 106 executes a reset processing same as that in step S115 in Fig. 4 and a payout processing (step S803). The present processing is ended after step S803.

00 C According to the above-mentioned slot game execution processing, the player can play plural slot games simultaneously by placing a bet with a predetermined bet amount.

ci And then, if the internally stored credit amount exceeds "100", a bet with a bet amount corresponding to surplus of the credit C is placed automatically. In addition, the slot games are S executed continuously until the internally stored credit amount 00 becomes equal to or smaller than "100". Furthermore, if the 0O S number of continuous games Tn becomes reaches the activation indicating frame 51 blinks as a visual effect and the payout rate change processing is executed. The payout rate change processing provides the player with a payout twice as much as a normal payout. The continuous execution of the slot games is terminated when the internally stored credit amount becomes equal to or smaller than "100". A bet must be placed by inserting a medal(s) or pressing the bet switch 25 for each single game after the continuous execution of the games has been terminated. However, if the internally stored credit amount exceeds "100" again, the slot games are executed continuously.

If the player wants to forcibly terminate the continuous execution of the slot games, the player can terminate the continuous execution by pressing the stop switch 31.

According to the slot machine or playing method of the slot machine of the present embodiment as described above, since plural slot game areas are provided, plural slot games can be simultaneously played with a single bet operation. In addition, since the slot games are continuously executed within a limit of the credit amount owned by the player, the player can enjoy multiple game plays continuously without placing a bet on each game play. As a result, since the player is not interrupted 00 S by a cumbersome operation such as inserting medal(s), the player can concentrate on the game without losing motivation for the game. Furthermore, since the games are executed continuously, the player can expect a larger payout amount. Therefore, an entertaining feature can be further enhanced.

c-i In addition, according to the slot machine or playing method of the slot machine of the present embodiment, a bet is 1 placed automatically within a limit of the credit amount owned 00 S by the player if the credit amount owned by the player exceeds a predetermined amount. No bet will be placed automatically if the credit amount owned by the player is equal to or less than the predetermined amount. Therefore, the player can play the games continuously without worrying that all the credits may be lost.

In addition, according to the slot machine or playing method of the slot machine of the present embodiment, the payout rate is changed if the number of continuous games has reached a predetermined number. Thus, the player may be provided with a more advantageous payout by executing the game. Therefore, the player can have stronger motivation for playing the games continuously.

In addition, according to the slot machine or playing method of the slot machine of the present embodiment, if the number of continuous games has reached a predetermined number, the player is notified by a visual effect. Thus, the player can easily recognize that the number of continuous games has reached the predetermined number and then the payout rate has been raised. Therefore, the player can be motivated for playing the games continuously.

Furthermore, according to the slot machine or playing 00 S method of the slot machine of the present embodiment, continuous execution of the games is terminated by the player's game terminating operation via the input device. Thus, the player c-i can prevent disadvantages due to placing continuous bets when the player does not want to play the games continuously.
