DETAILED DESCRIPTION OF THE EMBODIMENTS Configuration of a slot machine according to one embodiment of the present invention and a playing method thereof 15 will be described below with reference to the drawings. [Playing method of the slot machine] First, referring to Fig. 1, the flow of the playing method of the slot machine of the present embodiment will be described. When executing a game play, the slot machine of the present 20 embodiment first receives a bet on a unit game, which is an executing unit of slot games (step S11). Specifically, medals or coins are inserted, or a bet of monetary information (credits) is received. Upon reception of a bet on the unit game, the slot machine next receives a wager for an insurance pay 25 (referred to as "rescue pay" hereinafter; "insurance pay" and "rescue pay" are both pending applications for trademark registration) (step S12). The term "rescue pay" means, as described below, a payout of a progressive bonus when (i) the number of unit games without 30 a predefined payout amount (e.g., corresponding to 60 or more 9 medals per bet) has reached an upper limit (e.g., 1000 games), or (ii) wagers for successive unit games without a predefined payout amount has reached an upper limit (e.g., equivalent to 3000 medals). 5 The term "progressive bonus" means all of or a portion of gaming monetary value accumulated according to the plays on the slot machine. For example, the "progressive bonus" means any one of or a combination of: (i) accumulated value of the wager for the insurance pay; (ii) accumulated value of a portion 10 of the wager on the unit game; and (iii) accumulated value of a portion of the payout for a specific outcome of the unit game. Next, the slot machine executes a slot game (step S13). In the slot game, symbols are scrolled on each of three display areas Ql to Q3 triggered by the player's pressing down a start 15 switch 27, and are subsequently stopped. Then, if the combination of the symbols displayed on the display areas Ql to Q3 (outcome of the slot game) turns out to be a winning combination, a payout is provided to the player according to the winning combination. Subsequently, the number of executed 20 games (or expended bet amount) is counted (step S14). Next, it is determined whether or not the outcome of the slot game is a specific outcome (step S15) . Here, "specific outcome" is, for example, a case in which the payout per credit reaches or exceeds 60. Specifically, it is a case when "DOUBLE" 25 (specific symbol) or "triple BAR" (specific symbol) shown in Fig. 26 has aligned across the three display areas Q1 to Q3. Then, in the case of the specific outcome (YES in step S15), the number of executed games (or expended bet amount) counted in the processing in step S14 is reset (step S19) . Subsequently, 30 a payout is provided to the player according to the specific 10 outcome (step S20). On the other hand, if the outcome of the game is not a specific outcome (NO in step S15), it is determined whether or not the current game is a game with a rescue pay (referred to 5 as a "rescue game", hereinafter) (step S16) . In case of the rescue game, it is determined whether or not the number of executed games has reached an upper limit (predefined value) (step S17) . Then, if the number of executed games has reached the upper limit, a progressive bonus is paid out to the player 10 (step S18) . Alternatively, it is determined whether or not the expended bet amount has reached an upper limit and, if the expended bet amount has reached the upper limit, a progressive bonus is paid out to the player. With the playing method of the slot machine of the present 15 embodiment, as described above, a progressive bonus is paid out to the player if the number of executed games has reached an upper limit during the rescue games, or if the expended bet amount have reached an upper limit. [Configuration of the slot machine] 20 Next, an arrangement of the slot machine of the present embodiment will be described, referring to Figs. 2 and 3. A slot machine 10 of the present embodiment includes a cabinet 11 and a top box 12 provided on top of the cabinet 11, as shown in Fig. 2. The cabinet 11 has a main door 13.

The controller 40 electrically controls the slot machine 10. The hopper 44 controls insertion, storage, and payout of medals. 30 In the present embodiment, medals are used for a wager 11 when playing a game. Gaming media for the wager is not only limited to medals, but coins, tokens, electronic money, or other equivalent electronic value information (credits) may also be used. The main door 13 is attached to the cabinet 11 so that 5 it can be opened and closed. The lower LCD 16 is disposed on an upper portion of the main door 13. The lower LCD 16 displays images relating to a variety of games including a slot game. In the slot game, symbols are rearranged after being scrolled on each of the three display 10 areas Ql to Q3 arranged laterally. Then, a predefined payout is provided to the player (with medals or credits) if the combination of the symbols rearranged on the display areas Ql to Q3 turns out to be a winning combination (see Fig. 26). A medal insertion slot 21 and a bill validator 22 are 15 disposed at a lower part of the lower LCD 16. Medals are inserted into the medal insertion slot 21 when playing a game. The bill validator 22 validates bills and accepts valid ones. Various operational switches are disposed nearby the medal insertion slot 21 and the bill validator 22. In the present 20 embodiment, a cash-out switch 23, a max bet switch 24, a bet switch 25, a repeat bet switch 26, and a start switch 27 are provided as operational switches. The bet switch 25 is a switch for determining credits to be bet on the slot game, which is executed on the lower LCD 16. 25 Each time the bet switch 25 is pressed, a credit equivalent to one medal is bet. The Repeat bet switch 26 is a switch for placing a bet with the credits as bet on the previous game. The start switch 27 is a switch for starting the slot game on the lower LCD 16 after credits are bet. After the medal(s) 30 is inserted into the medal insertion slot 21 or credits are bet 12 by the bet switch 25, the slot game on the display areas Ql to Q3 of the lower LCD 16 is started by pressing the start switch 27. The cash-out switch 23 is a switch for paying out medals. The medals are paid out onto a medal tray 18 from a medal cash-out 5 opening 28 disposed on the front lower part of the main door 13. The max bet switch 24 is a switch for placing a bet with maximum credits (e.g., three medals) that can be bet on a single game by one pressing. The maximum credits that can be bet on 10 a single slot game may be changed by operation of the administrator. For example, credits equivalent to 50 medals can be bet. A foot display 34 is disposed on the lower front of the main door 13. Various images relating to the game (such as characters of the slot machine 10) are displayed on the foot 15 display 34. Lamps 47 are provided on both sides of the foot display 34. The lamp 42 emits light based on a preset light emission pattern. The medal cash-out opening 28 is provided on the lower part of the foot display 34. An upper LCD 33 is disposed on 20 the front of the top box 12. The number of medals to be paid out according to the combination of the symbols and other effect images are displayed on the upper LCD 33. Speakers 29 are provided on the top box 12. A ticket printer 35, a card reader 36, a data display 37, and a keypad 38 are disposed on the lower 25 part of the upper LCD 33. The ticket printer 35 prints out a ticket 39 having data such as a possessing credit value, time and date, identification number of the slot machine 10 printed thereon as a bar code. The player can play a game at another slot machine by using 30 the bar-coded ticket 39, and exchange the bar-coded ticket 39 13 for bills at a predefined site in an amusement facility (e.g., a cashier in the casino). A smart card can be inserted into the card reader 36. The card reader 36 reads the data from the smart card and writes the data onto the smart card. The smart 5 card is carried by the player. The smart card stores the player's identification data and gaming history data. Fig. 3 is a block diagram illustrating the electric configuration of the controller 40 and various devices connected to the controller 40, which are provided in the slot 10 machine 10 of the present embodiment. The controller 40 shown in Fig. 3 is a microcomputer. The controller 40 includes interface circuits 102, an I/O bus 104, a CPU 106, a ROM 108, a RAM 110, a signal communication interface circuit 111, a random number generator (RNG) 112, a speaker drive circuit 122, 15 a hopper drive circuit 124, a counter 128, and a display controller 140. The interface circuits 102 are connected to the I/O bus 104. The I/O bus 104 executes input and output of data signals and address signals with the CPU 106. The start switch 27 is 20 connected to the interface circuits 102. The start signal output from the start switch 27 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predefined signal by the interface circuits 102. The bet switch 25, the max bet switch 24, the repeat bet 25 switch 26, and the cash-out switch 23 are connected to the interface circuit 102. The switching signal output from each of the switches 23 - 26 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predefined signal by the interface circuits 102. 30 A medal sensor 43 is connected to the interface circuits 14 102. The medal sensor 43 detects medals, which have been inserted into the medal insertion slot 21. The medal sensor 43 is provided inside the medal insertion slot 21. The detection signal output from the medal sensor 43 is transmitted 5 to the CPU 106 via the I/O bus 104, after having been converted into a predefined signal by the interface circuits 102. The ROM 108 storing a system program and the RAM 110 storing various data are connected to the I/O bus 104. The RNG 112, the signal communication interface circuit 111, the 10 display controller 140, the hopper drive circuit 124, the speaker drive circuit 122, and the counter 128 are also connected to the I/O bus 104. The CPU 106, triggered by receiving the start signal from the start switch 27, reads a game execution program and executes 15 a slot game. The game execution program is a program for executing the slot game on the lower LCD 16 through the display controller 140. In other words, the game execution program is programmed so as to execute a slot game in which the symbols comes to a stop after scrolling (the symbols which have been 20 arranged are rearranged) on respective display areas Q1 to Q3 (see Fig. 2) and a payout will be awarded when a winning combination is formed by the rearranged symbols. The signal communication interface circuit 111, which is connected to a hall server etc., transmits gaming history data 25 etc. of the slot machine 10 to the hall server. The signal communication interface circuit 111 receives various data transmitted from the hall server. Based on the random number generated by the RNG 112, it is determined whether or not to award a winning combination in the slot game on the lower LCD 30 16. 15 The counter 128 has the functions of (i) counting the number of times the unit game is executed (number of slot games executed on the display areas Q1 to Q3 = number of executed games), (ii) counting the number of inserted medals during successively 5 executed slot games, and (iii) counting the difference between the number of inserted medals and the number of paid-out medals during successively executed slot games. The "number of inserted medals during successively executed slot games" is an accumulated value of the inserted 10 medals. For example, if the slot game is executed ten times with three medals (credits) bet on each game, the number of inserted medals will be 30. Also, the "difference between the number of inserted medals and the number of paid-out medals during successively executed slot games" is an accumulated 15 value of difference value which is got by subtracting the number of paid-out medals from the inserted medals (in other words, a difference value which is got by subtracting the accumulated number of the paid-out medals from the accumulated number of the inserted medals) . For example, if the slot game is executed 20 ten times with three medals (credits) bet on each game, and a payout of ten medals (credits) is provided during the ten games, the difference will be 20. The counter 128 can be implemented inside the RAM 110. The speaker drive circuit 122 outputs audio data to the 25 speakers 29. In other words, the CPU 106 reads the audio data stored in the ROM 108 and transmits the audio data to the speaker drive circuit 122 via the I/O bus 104. In this manner, predefined sound effects are output from the speakers 29. The hopper drive circuit 124 outputs a cash-out signal to the hopper 30 44 when providing a cash-out. In other words, the cash-out 16 signal is output by pressing the cash-out switch 23. The CPU 106 outputs, when the cash-out signal is input, a drive signal to the hopper drive circuit 124 via the I/O bus 104. As a result, the hopper 44 cash out medals equivalent to the credits stored 5 in a predefined memory area of the RAM 110. The display controller 140 controls display of the slot game executed on the lower LCD 16. In other words, the CPU 106 generates an image display signal according to the progress and outcome of the slot game and outputs the image display signal 10 to the display controller 140 via the I/O bus 104. Upon input of the image display signal, the display controller 140 generates a drive signal of the lower LCD 16 based on the image display signal and outputs it to the lower LCD 16. In this manner, various images such as effect images or explanatory 15 images of the game are displayed on the lower LCD 16. A touch-screen 19 is provided on the surface of the lower LCD 16. When the player touches the touch-screen 19, the touch position is detected and transmitted as data to the CPU 106. In addition, the display controller 140 also controls display 20 of various images such as effect images or explanatory images of the game on the upper LCD 33. [First embodiment] Next, the processing procedures according to a first embodiment for executing the unit game on the above-mentioned 25 slot machine 10 will be described. [Unit game execution processing) In the present embodiment, as shown in Fig. 4, a bet on the unit game is firstly received (step S31). Specifically, the insertion of the medal (s) into the medal insertion slot 21 30 or the pressing-down of the bet switches 24, 25 is detected by 17 the CPU 106. Next, a wager processing for the rescue pay is executed (step S32) . Here, the wager for the rescue pay is received via the touch-screen 19 on the lower LCD 16. The details will be described below, referring to the flow chart 5 shown in Fig. 5. Subsequently, it is determined whether or not the start switch 27 is pressed (step S33) . If the start switch 27 is pressed, the processing proceeds to step S34. Next, a slot game execution processing is executed (step S34) . Here, a processing of rearranging the symbols having been 10 arranged on respective three display areas Q1 to Q3 is executed. The details will be described below referring to the flow chart shown in Fig. 6. Next, a count processing of the unit game is executed (step S35). In this processing, the count-value of the counter 128 is incremented each time the unit game is 15 executed. The details will be described below, referring to the flow chart of Fig. 7. Next, a rescue pay execution processing is executed (step S36) . In this processing, if a payout equal to or larger than a specified amount (e.g., corresponding to 60 or more medals 20 per one medal) is not provided during a predefined number of executed unit games (e.g., 1000 games), a progressive bonus is awarded to the player. The details will be described referring to the flow chart of Fig. 8. Next, a payout processing is executed (step S37). In this processing, if a winning 25 combination is formed by the rearranged symbols on the three display areas Q1 to Q3, or if the progressive bonus is awarded, a payout is provided (as medals or credits) to the player. Subsequently, the processing proceeds to the next unit game. [Wager processing for rescue pay) 30 Next, the wager processing for the rescue pay shown in 18 step S32 of Fig. 4 will be described in detail with reference to the flow chart shown in Fig. 5. First, it is determined whether or not the current unit game is a rescue game (step S51). Then, if the current unit 5 game is not the rescue game (NO in step S51), the processing proceeds to step S52. On the other hand, if the current unit game is a rescue game (YES in step S51), the processing is completed. If the determination of step S51 is negative, a wager for 10 the rescue pay is received (step S52) . Next, an image notifying acceptance of the wager for the rescue pay is displayed on the upper LCD 33 and the lower LCD 16 (step S53). Fig. 27A shows the exemplary image displayed on the upper LCD 33. Fig. 27B shows the exemplary image displayed on the lower LCD 16. In 15 Fig. 27A, a "RESCUE OFF" image 200 is displayed indicating a state that a wager for the rescue pay has not currently been placed. Additionally, in Fig. 27B, a button 210 for presenting explanation of the rescue pay is displayed. When the player touches the button 210, the touch operation is detected by the 20 touch-screen 19 (see Fig. 3). Subsequently, as shown in Fig. 28, an explanatory image 220 of the rescue pay is displayed. In this example, a statement "What's rescue pay? If a x60 or higher payout has not been awarded during 1000 games with a wager for rescue pay, a 25 progressive bonus will be provided. Turn on rescue?" In this manner, the player is informed of the content of the rescue pay and prompted to select either one of selection images 221 and 222 indicating "YES" or "NO". If the "YES" image 221 is selected, the player is notified that a predefined wager is required for 30 activating the rescue game. Then, if a wager for the rescue 19 pay is placed, a "RESCUE ON" image 230 is displayed on the upper LCD 33 as shown in Fig. 29A. Additionally, as shown in Fig. 29B, a statement 236 "A progressive bonus will be provided if a x60 or higher payout has not been awarded during 1000 games." 5 is displayed on the lower LCD 16 in order to notify the player that the current unit game is a rescue game. Subsequently, it is determined whether or not a wager for the rescue pay has been placed (step S54) . If a wager for the rescue pay has not been placed (NO in step S54), the processing 10 is completed. On the other hand, if a wager for the rescue pay has been placed (YES in step S54), the processing proceeds to step S55. A predefined number of unit games to be executed are set as the rescue game (step S55). In addition, 20 credits are required for placing a wager for the rescue pay. The processing 15 is completed after step S55. [Execution processing of the slot game] Next, the execution processing of the slot game shown in step S34 of Fig. 4 will be described in detail with reference to the flow chart shown in Fig. 6. 20 The symbols to be stopped on each of the display areas Ql to Q3 are determined based on the random number generated by the RNG 112 (see Fig. 3) (step S71). Subsequently, the symbols are scrolled on each of the display areas Ql to Q3, and the scrolling symbols are stopped after a predefined time period 25 (e.g., five seconds) has elapsed (step S72) . Here, the stopped symbols have been determined in step S71. Subsequently, the processing proceeds to step S73. It is determined whether or not a winning combination awarding a payout has been formed on the display areas Q1 to 30 Q3 (step S73). The winning combinations are defined in the 20 payout table shown in Fig. 26. Specifically, each of the payouts is predefined, such as: (i) if three "DOUBLE" symbols are in alignment across the display areas Q1 to Q3, a payout of 800 credits is awarded per one credit; (ii) if three "triple 5 BAR" symbols are in alignment across the display areas Ql to Q3, a payout of 60 credits is awarded per one credit. Additionally, (iii) if three "double BAR" symbols are in alignment, (iv) if three "CHERRY" symbols are in alignment, (v) if three "single BAR" symbols are in alignment, (vi) if three 10 of any of "triple BAR" symbols, "double BAR" symbols, and "single BAR" symbols are in alignment; (vii) if two "CHERRY" symbols are in alignment, or (viii) if one "CHERRY" symbol has appeared, predefined payouts are awarded respectively. Subsequently, a processing for providing a payout is 15 executed according to the above-mentioned winning combination (step 574). It is determined whether or not specific symbols have been aligned across the display areas Q1 to Q3 (step S75) In the present embodiment, the specific symbols are the symbols that constitute a winning combination to award a x60 or higher 20 payout. Thus, as shown in Fig. 26, it is determined that the specific symbols are in alignment when three "DOUBLE" symbols or three "triple BAR" symbols are in alignment. Next, if it is determined that the specific symbols are in alignment (YES in step S75), the specific symbol alignment 25 flag is set to "1" (step S76) . Subsequently, the processing is completed. In the execution processing of the slot game shown in Fig. 6, a payout for is provided according to a winning combination when the winning combination has been rearranged. Furthermore, when specific symbols (three "DOUBLE" symbols or 30 three "triple BAR" symbols in the present embodiment) which 21 award a larger profit to the player are in alignment, a payout is provided according to the specific symbol and also the specific symbol alignment flag is set to "1". [Count processing of unit game) 5 Next, the count processing of the unit game of step S35 of Fig. 4 will be described in detail with reference to the flow chart shown in Fig. 7. First, the count-value Ta of the unit game is incremented [Ta=Ta+l] (step S91). Here, the initial value (when the slot 10 machine 10 is powered on) of the count-value Ta is zero. In addition, the count-value Ta is reset in step S93 described below. Note that the count-value Ta is a value for counting the number of executed unit games. Upon completion of step S91, the processing proceeds to step S92. 15 Next, it is determined whether or not the specific symbol alignment flag is "1" (step S92). In other words, it is determined whether or not the specific symbol alignment flag of step S76 of Fig. 6 is "1". If the specific symbol alignment flag is "1" (YES in step S92), the count-value Ta is reset (step 20 S93). Furthermore, the specific symbol alignment flag is also reset (step S94). Then, the wager for the rescue pay is also reset (step S95). In other words, if a payout of x6O or higher is awarded (that is, if the specific symbol alignment flag is 25 "1") (YES in step S92), both the count-value Ta of the unit game and the wager for the rescue pay in step S32 of Fig. 4 are reset. On the other hand, if the specific symbol alignment flag is not "1" (NO in step 92) , the processing is completed. In other words, if the specific symbol alignment flag is not "l" (NO in step 30 S92), the processing is completed and proceeds to the next unit 22 game after the count-value Ta is incremented. In the above-mentioned count processing of the unit game, if a winning combination with a x60 or higher payout is not awarded (specific symbols are not aligned), the count-value Ta 5 is incremented. On the other hand, if a winning combination with a x60 or higher payout is awarded (the specific symbols are in alignment), the count-value Ta is reset. In this manner, the number of successive unit games in which any specific symbols have not been aligned is counted. 10 [Rescue pay execution processing] Next, the rescue pay execution processing of step 536 of Fig. 4 will be described in detail with reference to the flow chart shown in Fig. 8. First, it is determined whether or not the current unit 15 game is a rescue game (step S101) . If the current unit game is a rescue game (YES in step S101), the processing proceeds to step S102. On the other hand, if the current unit game is not a rescue game (NO in step S101), the processing is completed. If the determination of step S101 is affirmative, it is 20 determined whether or not the count-value Ta is equal to a preset upper limit (predefined value) Tamax (e.g., Tamax = 1000) (step S102). Then, if Ta = Tamax (YES in step S102), the processing proceeds to step S103. On the other hand, if not Ta = Tamax (NO in step S102), the processing is completed. 25 If the determination of step S102 is affirmative, a processing for awarding a progressive bonus is executed (step S103). In other words, if the specific symbols have not been aligned although the number of executed games (= the count-value Ta) reaches the upper limit Tamax, a progressive bonus is 30 awarded to the player. Here, "the specific symbols are not 23 aligned" means that a winning combination with a x60 or higher payout is not awarded, specifically. Fig. 30A is an exemplary display of an image displayed on the upper LCD 33 when the count-value Ta is approaching the upper limit Tamax. Fig. 30B 5 is an exemplary display of an image displayed on the lower LCD 16. When the count-value Ta is "992", an image 224 is displayed on the upper LCD 33 in order to notify the player that eight games are left until a progressive bonus (rescue pay) is provided. In addition, an image 225 of an angel with folded 10 wings is also displayed on the lower LCD 16. Fig. 31A is an exemplary display of an image displayed on the upper LCD 33 when the count-value Ta is "999". Fig. 31B is an exemplary display of an image displayed on the lower LCD 16. An image 226 is displayed on the upper LCD 33 in order to 15 notify the player that one game is left until a progressive bonus (rescue pay) is provided. In addition, an image 227 of an angel with spread wings is also displayed on the lower LCD 16. Fig. 32A is an exemplary display of an image displayed on the upper LCD 33 when the count-value Ta reached the upper 20 limit Tamax = "1000". Fig. 32B is an exemplary display of an image displayed on the lower LCD 16. Images 316 and 252 are displayed on the upper LCD 33 and the lower LCD 16 respectively in order to notify that a progressive bonus (rescue pay) is going to be provided. 25 Fig. 33 is an example of an image displayed on the lower LCD 16 after the progressive bonus (rescue pay) has been provided. An image 255 is displayed on the lower LCD 16 in order to notify that the rescue pay is deactivated as a result of awarding the progressive bonus (rescue pay). In this manner, 30 the rescue pay execution processing shown in step S103 of Fig. 24 8 is executed. [Payout processing] Next, the payout processing shown in step S37 of Fig. 4 will be described in detail with reference to Fig. 9. 5 First, the payout amount is calculated based on the winning combination (step Sll) . Specifically, the payout amount of step S74 of Fig. 6 is calculated. Subsequently, the processing proceeds to step S112. Next, the payout amount according to the progressive 10 bonus is calculated (step S112) . In other words, when the progressive bonus of step S103 of Fig. 8 is to be provided, the accumulated wager for the rescue pay is calculated as the payout amount of the progressive bonus. As stated above, a wager for the rescue pay requires 20 credits. Here, these 20 credits have 15 been accumulated for the rescue pay. If the credits are accumulated 18 times, the payout amount for the rescue pay will be 360 credits. After step S112, the processing proceeds to step S113. The total payout amount is calculated according to the 20 winning combination and the progressive bonus, and then the payout according to the summed payout amount is cashed out from the cash-out opening 28 (see Fig. 2) with medals or coins (step S113). The payout may be provided by credits, in which case the credit counter of the slot machine is counted up. 25 Subsequently, the processing is completed. With the present embodiment, as thus described, the accumulated wager for the rescue pay is paid out as the progressive bonus when the count-value Ta reaches the upper limit (predefined value) Tamax during the rescue games. 30 [Exemplary modifications] 25 Next, several exemplary modifications of the first embodiment will be described. [First exemplary modification] The first exemplary modification differs from the 5 above-mentioned embodiment only in the payout process. The payout processing according to the first exemplary modification will be described below with reference to the flow chart shown in Fig. 10. First, the payout amount is calculated based on the 10 winning combination (step S121). Specifically, the payout amount of step S74 of Fig. 6 is calculated. Subsequently, the processing proceeds to step S122. Next, the payout amount according to the progressive bonus is calculated (step S122). In other words, when the 15 progressive bonus of step S103 of Fig. 8 is to be provided, accumulation of a portion of a bet amount on the unit games is calculated as the payout amount of the progressive bonus. Subsequently, the processing proceeds to step S123. The total payout amount is calculated according to the 20 winning combination and the progressive bonus, and then the payout according to the summed payout amount is cashed out from the cash-out opening 28 (see Fig. 2) with medals or coins (step S123). The payout may be provided by credits, in which case the credit counter of the slot machine is counted up. 25 Subsequently, the processing is completed. With the first exemplary modification, as thus described, accumulation of a portion of the bet amount on the unit games is paid out as the progressive bonus when the count-value reaches the upper limit (predefined value) Tamax during the 30 rescue game. 26 [Second exemplary modification) The second exemplary modification also differs from the above first embodiment only in the payout process. The payout processing according to the second exemplary modification will 5 be described below with reference to the flow chart shown in Fig. 11. First, the payout amount is calculated based on the winning combination (step S131). Specifically, the payout amount of step S74 of Fig. 6 is calculated. Subsequently, the 10 processing proceeds to step S132. Next, the payout amount according to the progressive bonus is calculated (step S132). In other words, when the progressive bonus of step S103 of Fig. 8 is to be provided, accumulation of a portion of the payout on the unit games is 15 calculated as the payout amount of the progressive bonus. Here, as stated above, the payout is provided when the outcome of the unit game turns out to be a specific outcome. Subsequently, the processing proceeds to step S133. The total payout amount is calculated according to the 20 winning combination and the progressive bonus, and then the payout according to the summed payout amount is cashed out from the cash-out opening 28 (see Fig. 2) with medals or coins (step S133). The payout may be provided by credits, in which case the credit counter of the slot machine is counted up. 25 Subsequently, the processing is completed. With the second exemplary modification, as thus described, accumulation of a portion of the payout on the unit game is paid out as the progressive bonus when the count-value reaches the upper limit (predefined value) Tamax during the rescue games. 30 [Third exemplary modification] 27 The third exemplary modification differs from the above first embodiment only in the count processing of the unit game. The count processing of the unit game according to the third exemplary modification will be described below with reference 5 to the flow chart shown in Fig. 12. First, it is determined whether or not the current unit game is a rescue game (step S141). If the current unit game is a rescue game (YES in step S141), the processing proceeds to step S142. Since the processing of steps S142 to S146 is 10 similar to that of steps S91 to S95 of Fig. 7, detailed description of the processing procedure is omitted. On the other hand, if the current unit game is not a rescue game (NO in step S141), the processing is completed without incrementing the count-value Ta. In other words, the 15 count-value Ta is not incremented in the unit games, which are not the rescue game. The count-value Ta is incremented only in the unit games, which are the rescue game. With the third exemplary modification, as thus described, the count-value Ta is incremented for each execution of the 20 rescue game. The progressive bonus is provided when the count-value Ta reaches the upper limit Tamax. [Second embodiment) Next, the processing procedure according to the second embodiment for executing the unit game on the above-mentioned 25 slot machine 10 will be described. [Unit game execution processing] Fig. 13 is a flow chart illustrating the processing procedure of the unit game executed on the slot machine (gaming machine) 10 according to the second embodiment. Comparing the 30 unit game execution processing of Fig. 13 (the present 28 embodiment) with the unit game execution processing of Fig. 4 (the first embodiment), steps S151 to S154 of Fig. 13 are identical to steps S31 to S34 of Fig. 4 and step S157 of Fig. 13 is identical to step S37 of Fig. 4. Steps S155 and S156 of 5 Fig. 13 differ from steps S35 and S36 of Fig. 4. [Count processing of the expended bet amount] The count processing of the expended bet amount of step S155 of Fig. 13 is described with reference to the flow chart shown in Fig. 14. 10 First, a newly placed bet amount a is added to the count-value Tb of the current expended bet amount (accumulation of the expended bet amount) [Tb=Tb+a] (step S171). Here, the initial value (when the slot machine 10 is powered on) of the count-value Tb is zero. In addition, the count-value Tb is 15 reset in step S173 described below. Note that the count-value Tb is an accumulated value of the bet amount (number of medals or credits) placed on successive unit games. If three medals are bet on a unit game, for example, it results in a=3 and a count-value of Tb=Tb+3. Upon completion of step S171, the 20 processing proceeds to step S172. Next, it is determined whether or not the specific symbol alignment flag is "1" (step S172). In other words, it is determined whether or not the specific symbol alignment flag of step S76 of Fig. 6 is "1". If the specific symbol alignment 25 flag is "l" (YES in step S172), the count-value Tb is reset (step S173). Furthermore, the specific symbol alignment flag is also reset (step S174). Then, the wager for the rescue pay is also reset (step S175) . In other words, if a payout of x60 or higher 30 is awarded, both the count-value Tb of the expended bet amount 29 and the wager for the rescue pay in step S152 of Fig. 13 are reset. On the other hand, if it is determined that the specific symbol alignment flag is not "1" (NO in step 172), the processing 5 is completed. In other words, if the specific symbol alignment flag is not "1"(NO in step 172), the processing is completed and proceeds to the next unit game after the count-value Tb is counted (accumulated). In the above-mentioned count processing, if a winning 10 combination with a x60 or higher payout is not awarded (specific symbols are not aligned), a newly placed bet amount a (e.g., a=3) is added to the count-value Tb. In this manner, the expended bet amount during successive unit games in which any specific symbols have not been aligned is counted. 15 Additionally, if a winning combination with a x60 or higher payout is awarded (specific symbols are in alignment), the count-value Tb is reset. [Rescue pay execution processing] Next, the rescue pay execution processing of step S156 20 of Fig. 13 will be described in detail with reference to the flow chart shown in Fig. 15. First, it is determined whether or not the current unit game is a rescue game (step S191). If the current unit game is a rescue game (YES in step S191), the processing proceeds 25 to step S192. On the other hand, if the current unit game is not a rescue game (NO in step S191) , the processing is completed. If the determination of step S191 is affirmative, it is determined whether or not the count-value Tb of the expended bet amount is equal to a preset upper limit Tbmax (e.g., Tbmax 30 = 3000) (step S192) . Then, if Tb = Tbmax (YES in step S192), 30 the processing proceeds to step S193. On the other hand, if not Tb = Tbmax (NO in step S192), the processing is completed. If the determination of step S192 is affirmative, a processing for awarding a rescue pay is executed (step S193) . 5 In other words, if the specific symbols have not been aligned although the expended bet amount reaches the upper limit Tbmax, a progressive bonus is awarded to the player. Here, "the specific symbols are not aligned" means that a winning combination with a x60 or higher payout is not awarded, 10 specifically. With the present embodiment, as thus described, the progressive bonus is paid out when the count-value Tb (accumulation of the expended bet amount) reaches the upper limit Tbmax during the rescue games. 15 [Exemplary modifications) Next, an exemplary modification of the second embodiment will be described with reference to the flow chart shown in Fig. 16. The exemplary modification differs from the above-mentioned embodiment only in the count processing of the 20 expended bet amount. In the following, the count processing of the expended bet amount of the exemplary modification will be described with reference to the flow chart shown in Fig. 16. First, it is determined whether or not the current unit game is a rescue game (step S201). If the current unit game 25 is a rescue game (YES in step S201), the processing proceeds to step S202. Since the processing of steps S202 to S206 is similar to that of steps S171 to S175 of Fig. 14, detailed description of the processing procedure is omitted. On the other hand, if the current unit game is not a rescue 30 game (NO in step S201), the processing is completed without 31 counting the count-value Tb (without adding a newly placed bet amount a) . In other words, the count-value Tb is not counted (accumulated) in the unit games, which are not the rescue game. The count-value Tb is counted (accumulated) only in the unit 5 games, which are the rescue game. With such an exemplary modification, the count-value Tb is counted (accumulated) at each wager in the rescue games. The progressive bonus is provided when the count-value Tb reaches the upper limit Tbmax. 10 Additionally, with the second embodiment and its exemplary modification, a newly placed bet amount a on the unit game is added to the count-value Tb. However, it may be arranged such that a difference between a bet amount on a unit game and a payout amount for the unit game is added to the count-value 15 Tb. In this case, the count-value Tb is accumulated according to the player's substantial loss. In other words, a shown in step S171 of Fig. 14 or S202 of Fig. 16 is a difference between a newly placed bet amount on a new unit game and a payout amount for the new unit game. The new difference a (= difference 20 between the bet amount on the new unit game and the payout amount for the new unit game) is added to the current count-value Tb of the accumulated difference [Tb=Tb+a). Additionally, the above-mentioned first embodiment is an example wherein the progressive bonus is provided when the 25 count-value Ta of the number of the executed unit games reaches the upper limit Tamax. Also, the above-mentioned second embodiment is an example wherein the progressive bonus is provided when the count-value Tb of the expended bet amount during successive unit games reaches the upper limit Tbmax. It 30 may be arranged such that the progressive bonus is awarded using 32 the combination of these. In other words, the progressive bonus may be provided if either one of the following cases is achieved: when the count-value Ta reaches the upper limit Tamax; or when the count-value Tb reaches the upper limit Tbmax. 5 [Third embodiment] Next, the processing procedure according to the third embodiment for executing the unit game on the above-mentioned slot machine 10 will be described. The unit game execution processing of the present embodiment is generally similar to 10 that of the first embodiment. However, the count processing of the unit game and the rescue pay execution processing of the present embodiment differ from those of the first embodiment (steps S35 and S36 in Fig. 4) . Other processings of the present embodiment are identical to those of the first embodiment (steps 15 S31 to S34 and S37). Therefore, the count processing of the unit game and the rescue pay execution processing of the third embodiment is described below with reference to the flow charts shown in Figs. 17 and 18. [Count processing of unit game) 20 In the count processing of the unit game shown in Fig 17, the count-value Ta of the unit game is incremented [Ta=Ta+l] (step 5211) at first. Note that the count-value Ta is a value for counting the number of executed unit games. The initial value of the count-value Ta is zero. Upon completion of step 25 S211, the processing proceeds to step S212. Next, it is determined whether or not the specific symbol alignment flag is "1" (step S212) . If the specific symbol alignment flag is "1" (YES in step S212) , the wager for the rescue pay is reset (step S213). Furthermore, the specific symbol 30 alignment flag is also reset (step S214) . In other words, if 33 a payout of x60 or higher is awarded (that is, if the specific symbol alignment flag is "1") (YES in step S212), the wager for the rescue pay in step S32 of Fig. 4 is reset. It is the different point from the first embodiment that the count-value 5 Ta is not reset. On the other hand, if it is determined that the specific symbol alignment flag is not "1" (NO in step 212), the processing is completed. In other words, if the specific symbol alignment flag is not "1" (NO in step S212), the processing is completed 10 and proceeds to the next unit game after the count-value Ta is incremented. [Rescue pay execution processing] Next, the rescue pay execution processing of the third embodiment will be described with reference to the flow chart 15 shown in Fig. 18. First, it is determined whether or not the current unit game is a rescue game (step S251). If the current unit game is a rescue game (YES in step S251), the processing proceeds to step S252. On the other hand, if the current unit game is 20 not a rescue game (NO in step S251) , the processing is completed. If the determination of step S251 is affirmative, it is determined whether or not the count-value Ta is equal to a preset upper limit Tamax (e.g., Tamax = 1000) (step S252). Then, if Ta = Tamax (YES in step S252), the processing proceeds to step 25 S253. On the other hand, if not Ta = Tamax (NO in step S252), the processing is completed. If the determination of step S252 is affirmative, a processing for awarding a progressive bonus is executed (step S253). In other words, if the specific symbols have not been 30 aligned although the number of executed games (= the count-value 34 Ta) reaches the upper limit Tamax, a progressive bonus is awarded to the player. Here, "the specific symbols are not aligned" means that a winning combination with a x60 or higher payout is not awarded, specifically. Then, the processing 5 proceeds to step S254. The count-value Ta is reset (step S254) . In the present embodiment, if a winning combination with a x60 or higher payout is awarded (that is, if the specific symbol alignment flag is "1"), the wager for the rescue pay is reset. However, the count-value Ta is not reset at this point. The 10 count-value Ta is reset when the rescue pay is awarded (step S254 in Fig. 18). Therefore, the count-value Ta is not reset in case that the specific symbol alignment flag turns to "1" before the count-value reaches the upper limit Tamax. Thus, if the player places a new wager for a rescue pay again, a 15 progressive bonus will be provided when the count-value Ta comes to reach the upper limit Tamax. In the present embodiment, as described above, the count-value Ta is not reset until a progressive bonus is provided. 20 [Exemplary modifications] Next, an exemplary modification of the third embodiment will be described with reference to the flow chart shown in Fig. 19. First, it is determined whether or not the current unit 25 game is a rescue game (step S231) . If the current unit game is a rescue game (YES in step S231), the processing proceeds to step S232. Since the processing of steps S232 to S235 is similar to that of steps S211 to S214 of Fig. 17, detailed description of the processing procedure is omitted. 30 On the other hand, if the current unit game is not a rescue 35 game (NO in step S231), the processing is completed without incrementing the count-value Ta. In other words, the count-value Ta is not incremented in the unit games, which are not the rescue game. The count-value Ta is incremented only 5 in the unit games, which are the rescue game. With the present exemplary modification, the count-value Ta is incremented only in the unit games, which are the rescue game. [Fourth embodiment] 10 Next, the processing procedure according to the fourth embodiment for executing the unit game on the above-mentioned slot machine 10 will be described with reference to the flow chart shown in Fig. 20. [Unit game execution processing] 15 In the present embodiment, a bet on the unit game is firstly received (step S271). Specifically, the insertion of the medal(s) into the medal insertion slot 21 or the pressing-down of the bet switches 24, 25 is detected by the CPU 106. 20 Next, a count processing of the unit game is executed (step S272) . The count processing of the unit game will be described below, referring to the flow chart shown in Fig. 21. Subsequently, it is determined whether or not the count-value Ta reaches a preset criterion value Tal (e.g., Tal = 100) (step 25 S273) . Then, if the count-value Ta reaches the criterion value Tal (YES in step S273), the processing proceeds to step S274. On the other hand, if the count-value Ta does not reach the criterion value Tal (NO in step S273), the processing proceeds to step S275. 30 If the determination of step S273 is affirmative, a wager 36 processing for the rescue pay is executed (step S274) . Here, the wager for the rescue pay is received via the touch-screen 19 on the lower LCD 16. In other words, the wager for the rescue pay can be placed only when the count-value Ta has reached the 5 criterion value Tal. Since the wager processing for the rescue pay is identical to the processing shown in Fig. 5, detailed description of the processing procedure is omitted. Subsequently, it is determined whether or not the start switch 27 is pressed (step S275) . If the start switch 27 is pressed, 10 the processing proceeds to step S276. Next, a slot game execution processing is executed (step S276). Here, a processing of rearranging the symbols having been arranged on respective three display areas Ql to Q3 is executed. Since the slot game execution processing is 15 identical to the processing shown in Fig. 6, detailed description of the processing procedure is omitted. Next, a reset processing is executed (step 5277). The details will be described below, referring to the flow chart of Fig. 22. Next, a rescue pay execution processing is executed (step 20 S27 8) . In this processing, if a payout equal to or larger than a specified amount (e.g., a x60 or higher payout) has not been awarded during a predefined number of executed unit games, a progressive bonus is awarded to the player. Since the rescue pay execution processing is identical to the processing shown 25 in Fig. 8, detailed description of the processing procedure is omitted. Next, a payout processing is executed (step S279). In this processing, if a winning combination is formed by the rearranged symbols on the three display areas Ql to Q3, or if 30 the progressive bonus is awarded, a payout is provided (as 37 medals or credits) to the player. Subsequently, the processing proceeds to the next unit game. [Count processing of unit game] Next, the count processing of the unit game of step S272 5 of Fig. 20 will be described with reference to the flow chart shown in Fig. 21. Here, the count-value Ta of the unit game is incremented [Ta=Ta+1] (step S291) . Subsequently, the processing is completed. 10 [Reset processing] Next, the reset processing of step S277 of Fig. 20 will be described with reference to the flow chart shown in Fig. 22. First, it is determined whether or not the specific symbol alignment flag is "1" (step S301) . If the specific symbol 15 alignment flag is "1" (YES in step S301), the count-value Ta is reset (step S302). Furthermore, the specific symbol alignment flag is also reset (step S303). Then, the wager for the rescue pay is also reset (step S304). In other words, if the specific symbol alignment flag is 20 "1" (that is, if a payout of x6O or higher is awarded) (YES in step S301), both the count-value Ta of the unit game and the wager for the rescue pay in step S274 of Fig. 20 are reset. On the other hand, if the specific symbol alignment flag is not "1" (NO in step 301), the processing is completed. In other 25 words, if the specific symbol alignment flag is not "1" (NO in step S301), the processing is completed and proceeds to the next unit game without resetting the count-value Ta, the specific symbol alignment flag, and the wager for the rescue pay. In the present embodiment, as described above, the wager 30 for the rescue pay can be placed only when the count-value Ta 38 of the number of the executed unit games has reached the criterion value Tal. [Fifth embodiment) Finally, the processing procedure according to the fifth 5 embodiment for executing the unit game on the above-mentioned slot machine 10 will be described. [Unit game execution processing] Fig. 23 is a flow chart illustrating the procedure of the unit game execution processing according to the fifth 10 embodiment. After starting a unit game, a bet on the unit game is received (step S311). Specifically, the insertion of the medal (s) into the medal insertion slot 21 or the pressing-down of the bet switches 24, 25 is detected by the CPU 106. 15 Next, a count processing of the expended bet amount is executed (step S312) . The count processing of the expended bet amount will be described referring to the flow chart of Fig. 24. Subsequently, it is determined whether or not the count-value Tb, which is counted in the count processing of the 20 expended bet amount of step S312, reaches a preset criterion value Tbl (e.g., Tbl = 300) (step S313) . Then, if the count-value Tb reaches the criterion value Tbl (YES in step S313), the processing proceeds to step S314. On the other hand, the count-value Tb does not reach the criterion value Tbl (NO 25 in step S313), the processing proceeds to step S315. If the determination of step S313 is affirmative, a wager processing for the rescue pay is executed (step S314) . Here, the wager for the rescue pay is received via the touch-screen 19 on the lower LCD 16. In other words, the wager for the rescue 30 pay can be placed only when the count-value Tb has reached the 39 criterion value Tbl. Since the wager processing for the rescue pay is identical to the processing shown in Fig. 5, detailed description of the processing procedure is omitted. Subsequently, it is determined whether or not the start switch 5 27 is pressed (step S315). If the start switch 27 is pressed, the processing proceeds to step S316. Next, a slot game execution processing is executed (step S316). Since the slot game execution processing is identical to the processing shown in Fig. 6, detailed description of the 10 processing procedure is omitted. Next, a reset processing is executed (step S317). The details will be described below, referring to the flow chart of Fig. 25. Next, a rescue pay execution processing is executed (step S318) . In this processing, if a payout equal to or larger than 15 a specified amount (e.g., corresponding to 60 or more medals per one medal) is not provided during a predefined number of executed unit games, a progressive bonus is awarded to the player. Since the rescue pay execution processing is identical to the processing shown in Fig. 8, detailed description of the 20 processing procedure is omitted. Next, a payout processing is executed (step S319). In this processing, if a winning combination is formed by the rearranged symbols on the three display areas Ql to Q3, or if the rescue pay is awarded, a payout is provided (as medals or 25 credits) to the player. Subsequently, the processing proceeds to the next unit game. [Count processing of the expended bet amount) Next, the count processing of the expended bet amount of step S312 of Fig. 23 will be described with reference to the 30 flow chart shown in Fig. 24. 40 Here, a newly placed bet amount a is added to the count-value Tb of the current expended bet amount [Tb=Tb+a] (step S331) . Subsequently, the processing is completed. As mentioned above, a newly placed bet amount a on the 5 unit game is added to the count-value Tb. However, it may be arranged such that a difference between a bet amount on a unit game and a payout amount for the unit game is added to the count-value Tb. In this case, the count-value Tb is accumulated according to the player's substantial loss. In other words, 10 a shown in step S331 of Fig. 24 is a difference between a newly placed bet amount on a new unit game and a payout amount for the new unit game. The new difference a (= difference between the bet amount on the new unit game and the payout amount for the new unit game) is added to the current count-value Tb of 15 the accumulated difference [Tb=Tb+a]. [Reset processing] Next, the reset processing of step S317 of Fig. 23 will be described with reference to the flow chart shown in Fig. 25. First, it is determined whether or not the specific symbol 20 alignment flag is "1"1 (step 5351) . If the specific symbol alignment flag is "1" (YES in step S351), the count-value Tb is reset (step S352) . Furthermore, the specific symbol alignment flag is also reset (step S353). Then, the wager for the rescue pay is also reset (step S354). 25 In other words, if the specific symbol alignment flag is "1" (that is, if a payout of x60 or higher is awarded) (YES in step S351), both the count-value Tb of the expended bet amount and the wager for the rescue pay in step S314 of Fig. 23 are reset. 30 On the other hand, if the specific symbol alignment flag 41 is not "1" (NO in step 351), the processing is completed. In other words, if the specific symbol alignment flag is not "1" (NO in step S351), the processing is completed and proceeds to the next unit game without resetting the count-value Tb, the 5 specific symbol alignment flag, and the wager for the rescue pay. In the present embodiment, as described above, the wager for the rescue pay can be placed only when the count-value Tb of the expended bet amount has reached the criterion value Tbl. 10 The gaming machine and playing method of the present invention have been described above, based on the illustrated embodiments.
