Title: Gaming machine

Description:
CROSS REFERENCE TO RELATED APPLICATIONS  
      This application is based upon and claims the benefits of priorities from Japanese Patent Application No. 2005-342442 filed on Nov. 28, 2005, the entire contents of which are incorporated herein by reference.  
     FIELD OF THE INVENTION  
      The present invention relates to a gaming machine utilizing a payout table.  
     RELATED ART  
      In a conventional gaming machine, for example, Japanese Unexamined Patent Application Publication Number 2003-180908 discloses a video slot machine, in which the credit number having been won in a game is obtained as a result of calculation by multiplying the odds by the bet number. However, the odds are fixed for each winning combination and the player has little interest in the odds themselves such that the player tends to focus on whether the winning combination is established on the bet line or not, thereby causing the player to feel the game is monotonous.  
      In this respect, as means for preventing the monotony of the game, for example, U.S. Pat. Nos. 6,254,481 and 6,569,018 disclose a slot machine in which an image effect is performed on two display screens. That is, in the slot machine, an image effect is made such that one entire image is displayed on the two display screens jointly and, in the one entire image, for example, motion of a character displayed in a part of one of the display screens constituting the one entire image triggers motion of another character displayed in a part of the other display screen. Therefore, the image effect tries to attract the player&#39;s interest by utilizing the features of the two display screens.  
      And Japanese Unexamined Patent Application Publication Number 2003-111896 discloses a slot machine to try to make the player have a feeling that the base winning symbol combination table is unexpectedly changed to the special winning symbol combination table for a predetermined number of times, thereby causing different payouts to be paid out consecutively even though the identification information image having been stopped and displayed statically corresponds to a low payout.  
      However, the different payouts are paid out only when the identification information image stopped and displayed statically is assigned to a low payout. But the entire payouts are not subject to the different payouts such that the player has an only limited chance to feel the unexpected result. Therefore, it is likely that the player may feel monotony as the player continues to play the game.  
     SUMMARY OF THE INVENTION  
      In the present invention, a gaming machine utilizing the payout table, which can avoid monotony of the game, is provided. The gaming machine comprises: a first display for displaying a payout table of a game; and a processor in communication with the first display, wherein the processor is operable to: determine payout change information to change a payout of the payout table; and cause the first display to display the changed payout of the payout table based on the payout change information.  
      Further features of the present invention, its nature, and various advantages will be more apparent from the accompanying drawings and the following description of the preferred embodiment.

The VDP  85  forms images according to display contents determined by the image control CPU  83 , and outputs the resultant images to the upper liquid crystal display  3  and the lower liquid crystal display  4 . Accordingly, respective symbols and the like of the video reel  100  of  FIG. 7  are, by way of example, variably displayed and statically displayed in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C of the lower liquid crystal display  4  (see  FIG. 3 ). The video RAM  86  is configured as temporary storage means which is used when an image is formed with the VDP  85 .  
      When respective symbols of the video reel  100  which are variably displayed by being scrolled are stopped and displayed statically in the respective variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C, one symbol is stopped and displayed statically in each of the variable display parts  22 A to  22 C,  23 A to  23 C, and  24 A to  24 C. Various kinds of winning combinations are set up in advance on the basis of a plurality of kinds of combinations of the above-mentioned respective symbols (see  FIG. 9 ), and when a combination of the symbols corresponding to a winning combination is stopped along any of the activated pay lines L 1  to L 8 , coins are paid out from the coin payout opening  16  according to the winning combination. Such features are similar to those of conventional slot machines and hence explanations thereof are omitted here.  
      Referring back to  FIG. 5 , the CPU  50  is connected to LED  78  via an LED drive circuit  77 . When a large number of LEDs  78  are arranged on the front face of the slot machine  1  such that various kinds of effects are performed, the LED drive circuit  77  controls lighting of the LEDs on the basis of the drive signal from the CPU  50 . Further, the CPU  50  is connected to a sound output circuit  79  and a speaker  80 , and the speaker  80  generates various kinds of sound effects when performing various kinds of effects based on the signal outputted from the sound output circuit  79 .  
      Then, with reference to  FIG. 8 , an explanation is made for a lottery table to be utilized for determining the symbols which are stopped and displayed statically in the respective variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C in the case that the game is played in the slot machine  1  with the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C.  FIG. 8  is a drawing illustrating the lottery table of the symbols to be stopped and displayed statically in the case that the game is played with the nine variable display parts. Here, the lottery table shown in  FIG. 8  is stored in the ROM  51 .  
      In this respect, the symbols to be stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C are determined symbol by symbol for each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C. For this purpose, code numbers “0” to “9” are assigned, sequentially from the left, to the respective symbols which constitute the video reel  100  as shown in FIG.  7 , and a lottery table as shown in  FIG. 8  is provided. Then, nine random number values are sampled by the random number sampling circuit  56  so that the sampled numbers correspond to the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C, respectively.  
      By way of example, the lottery table of  FIG. 8  shows individual symbols which constitute the video reel  100  to be displayed in the variable display part  23 A. When a random number value sampled by the random number sampling circuit  56  is in the range of 0 to 1, the symbol of the scatter  101  assigned to the code number “0” is stopped and displayed statically in the variable display part  23 A. As to the code numbers from “1” to “9”, each symbol corresponds to each code number in the same way on the basis of the lottery table of  FIG. 8 .  
      Here, as to each symbol which constitutes the video reel  100  and is displayed in each of the other variable display parts  22 A to  22 C,  23 B and  23 C, and  24 A to  24 C, each symbol corresponding to each code number is stopped and displayed statically in the same way as each symbol which constitutes the video reel  100  of the variable display part  23 A is stopped and displayed statically as mentioned above.  
      Next, an explanation is made for winning combinations and payout rates thereof when the game is played in the slot machine  1  with the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C with reference to  FIG. 9 .  FIG. 9  is an explanatory diagram of the payout table showing the winning combinations and the payout rates thereof in the case of performing the game utilizing the nine variable display parts.  
      The payout table  123  as shown in  FIG. 9  is constituted of a payout table  121  of ‘ANY’ odds and a payout table  122  of ‘LINE’ odds, and is stored as a table in the ROM  51 .  
      In this respect, the payout table  121  of ‘ANY’ odds shows the payout rate of each symbol to the number of symbols of the same kind to be stopped and displayed statically in the variable display parts (see  FIG. 3 ) along the activated pay lines (see  FIG. 4 ) displayed on the lower liquid crystal display  4 . For example, when the random number values of any five variable display parts along the activated pay lines (see  FIG. 4 ) out of the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C are within the range from “2” to “19”, “ANY 5 of sea turtle” having a code number of ‘1’ (see  FIG. 8 ) is won. In this case, the five sea turtles  102  are stopped and displayed statically in the five variable display parts along the activated pay lines (see  FIG. 4 ), respectively (see  FIG. 7 ), and the payout rate of “1” is obtained. In a similar manner, each payout rate of ‘ANY’ odds is made on the basis of the payout table  121  of the ‘ANY’ odds as shown in  FIG. 9 .  
      The payout table  122  of ‘LINE’ odds shows the payout rate per line to the number of activated pay lines (see  FIG. 4 ) on which symbols of the same kind are stopped and displayed statically in the variable display parts (see  FIG. 3 ) along the activated pay lines (see  FIG. 4 ) displayed on the lower liquid crystal display  4 . For example, with regard to the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C, when any of the random number values of symbols which are displayed in all variable display parts along a single activated pay line (see  FIG. 4 ) out of the activated pay lines (see  FIG. 4 ) are within the range from “2” to “19”, “sea turtle—sea turtle—sea turtle” combination of code number ‘1’ (see  FIG. 8 ) is won with respect to the activated pay line (see  FIG. 4 ). In this case, every variable display part along the activated pay line (see  FIG. 4 ) shows statically the sea turtle  102  (see  FIG. 7 ), and the payout rate of “5” is obtained. Here, when a plurality of activated pay lines (see  FIG. 4 ) are entitled for winning the “sea turtle—sea turtle—sea turtle” combination, the payout rate may be calculated by multiplying the number of the activated pay lines by “5”. In a similar manner, each payout rate of ‘LINE’ odds is determined on the basis of the payout table  122  of the ‘LINE’ odds as shown in  FIG. 9 .  
      When the random number values of symbols to be displayed in three or more variable display parts along activated pay lines (see  FIG. 4 ) displayed on the lower liquid crystal display  4  are “0” or “1” with respect to the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C, the symbols of scatter  101  having a code number of ‘0’ are stopped and displayed statically, respectively (see  FIG. 7 ), in the three or more variable display parts along the activated pay lines (see  FIG. 4 ). Subsequently, a special game is developed on the lower liquid crystal display  4 . However, a detailed description thereof is omitted here.  
      Next, an explanation is made for a table to be used in selecting payout change information that changes the payout rates of the payout table  123  of the game with reference to  FIG. 13  when the game is played with the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C of the slot machine  1 .  
      The payout change information which changes the payout rates of the payout table  123  is selected in this embodiment by utilizing the table (see  FIG. 13 ) and a random number value sampled in the range of 0 to 127 by the random number sampling circuit  56 . As to the object of the payout change information to be selected, there are three patterns, that is, only the payout table  121  of ‘ANY’ odds, only the payout table  122  of ‘LINE’ odds, and both of the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds.  
      That is, the table of  FIG. 13  shows that, when the random number value sampled by the random number sampling circuit  56  is any one of “0” to “12”, the payout change information which doubles the payout of only the payout table  121  of ‘ANY’ odds is selected. On the other hand, when the random number value sampled by the random number sampling circuit  56  is any one of “13” to “25”, the payout change information (“×2”) which doubles the payout of only the payout table  122  of ‘LINE’ odds is selected. Further, when the random number value sampled by the random number sampling circuit  56  is any one of “26” to “31”, the payout change information which doubles the payout of both the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds is selected. Each of the payout change information (“×3”, ×4”, or “×5”) which changes payout by three times, four times or five times is selected similarly.  
      Next, when the game is played with the nine variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C of the slot machine  1 , an explanation is made for a table to be utilized in selecting an image pattern of bubble effect to be performed along with display of payout change information which changes the payout amount based on the payout table  123  of the game with reference to  FIG. 14 .  
      In this respect, the image pattern of the bubble effect performed along with display of the payout change information which changes the payout amount based on the payout table  123  is selected by using a table (see  FIG. 14 ) and a random number value sampled in the range from 0 to 127 by the random number sampling circuit  56 . That is, the table of  FIG. 14  shows that, when the random number value sampled by the random number sampling circuit  56  is any one from “0” to “53”, an image of bubble effect of a pattern having a small number of bubbles is selected. When the random number value sampled by the random number sampling circuit  56  is any one from “54” to “95”, an image of bubble effect of a pattern having an intermediate number of bubbles is selected. Further, when the random number value sampled by the random number sampling circuit  56  is any one from “96” to “127”, an image of bubble effect of a pattern having a large number of bubbles is selected.  
      Next, a main process program executed on the slot machine  1  is explained with reference to  FIG. 10 , which is the flowchart of the main process program. In  FIG. 10 , the start acceptance process of  FIG. 11  to be described later is first executed in step (abbreviated to “S” hereafter)  11 . In this process, a switch signal outputted from the spin switch  57 , the 1-BET switch  58 , the 3-BET switch  59 , the 5-BET switch  60 , or the 8-BET switch  61  on the basis of an operation of the spin (SPIN/REPEAT BET) button  12 , an operation of the 1-BET button  11 , an operation of the 3-BET button  13  or an operation of the 5-BET button  14  or the 8-BET button  15  is received. The game is started at the moment when the switch signal outputted from each switch is received.  
      Then, in S 12 , lottery process of  FIG. 12  to be described later is executed on the basis of the switch signal outputted from the spin switch  57 , the 1-BET switch  58 , the 3-BET switch  59 , the 5-BET switch  60 , or the 8-BET switch  61 .  
      In the following S 13 , a game process of  FIG. 15  to be described later is executed, and subsequently the other game process of S 14  is executed, thereby completing this main process program. In the other game process of S 14 , a special game is developed on the lower liquid crystal display  4  only if a predetermined condition with respect to the symbol of scatter  101  is satisfied. However, the detailed description of the game process is omitted here.  
      Next, an explanation is made for the start acceptance process program to be executed with the slot machine  1  with reference to  FIG. 11 , which shows a flowchart of the start acceptance process program. The start acceptance process is executed in S 11  of the main process program of  FIG. 10 . For the process, it is determined first, in S 21  of  FIG. 11 , whether a predetermined period of time (for example, 15 seconds) has elapsed. When the determination shows that the predetermined time has not elapsed (S 21 : NO), the program proceeds to S 23  without performing anything. On the other hand, when the determination shows that the predetermined time has elapsed (S 21 : YES), demonstration effect is performed on the upper liquid crystal display  3  and the lower liquid crystal display  4  in S 22 , and the program proceeds to S 23 . Then, in S 23 , it is determined whether an operation of the spin (SPIN/REPEAT BET) button  12 , an operation of the 1-BET button  11 , an operation of the 3-BET button  13 , or an operation of the 5-BET button  14  or 8-BET button  15  has been made. Here, when the determination shows that the operation of the 1-BET button  11  and the like has not been made (S 23 : NO), the program returns to S 21 , and the process mentioned above is repeated. On the other hand, when the determination shows that the operation of the 1-BET button  11 , etc. has been made (S 23 : YES), the demonstration effect is canceled, and the predetermined activated pay lines L 1  to L 8  are displayed on the lower liquid crystal display  4 . At the same time, as shown in  FIG. 17 , for example, the payout table  123  which is constituted of the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds is displayed on the upper liquid crystal display  3 . Thereafter, the program returns to the main process program of  FIG. 10 , and proceeds to a lottery process of S 12 .  
      Next, the lottery process program to be executed with the slot machine  1  is explained with reference to  FIG. 12 , which shows a flowchart of the lottery processing program. The Lottery process is executed in S 12  of the main process program of  FIG. 10 . For the process, the program first proceeds to S 31  of  FIG. 12 , and symbol determination process is executed. Here, the symbol which is stopped and displayed statically in each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C during the game (S 42  of  FIG. 15 ) is determined for each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C. More specifically, as mentioned above, nine random number values for the respective variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C are sampled from the range from 0 to 127 by the random number sampling circuit  56  to determine the symbols to be stopped and displayed statically as code numbers thereof are utilized on the basis of the lottery table of  FIG. 8 . When the symbol to be stopped and displayed statically is determined for each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C, a winning combination determination process is executed in S 32 . More specifically, in this winning combination determination process, as mentioned above, the winning combinations along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4  and payout rates thereof are determined on the basis of the table stored in the ROM  51  as the payout table  123  of  FIG. 9  is utilized with the code numbers acquired in the above S 31 .  
      Then, the lottery process for changing the payout table is executed in S 33 . More specifically, in this lottery process for changing the payout table, the payout change information for changing the payout of the payout table  123  is selected as the table of  FIG. 13  and the random number values sampled from the range of 0 to 127 by the random number sampling circuit  56  are utilized, as mentioned above. For example, when the random number value sampled by the random number sampling circuit  56  is any one from “121” to “127”, the payout change information for changing payout by 5 times is selected for both of the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds.  
      The random number lottery in S 33  may be performed simultaneously with the random number lottery in S 31 .  
      More specifically, in this lottery process for changing the payout table, as mentioned above, one image pattern is selected from the three image patterns of bubble effect as the table of  FIG. 14  and the random number value sampled from the range of 0 to 127 by the random number sampling circuit  56  are utilized. For example, when the random number value sampled by the random number sampling circuit  56  is any one of “96” to “127”, an image pattern of bubble effect with a large number of bubbles is selected.  
      When the program proceeds to S 34 , an instruction process of payout change is executed. In this instruction process of payout change, the payout change information (a multiplier thereof) selected in the above S 33  is stored in the RAM  52 . The payout change information (a multiplier thereof) stored in the RAM  52  is used when the amount of payout is paid out in the game (S 43  of  FIG. 15 ).  
      In the subsequent S 35 , an effect image process is executed. In this effect image process, the payout change information and the bubble effect having been selected in the above S 33  are displayed. More specifically, as shown in FIGS.  18  to  20  in this order, the image pattern of the bubble effect having been selected in the above S 33  is first displayed in the lower liquid crystal display  4  and then is shifted from the lower liquid crystal to the upper liquid crystal display  3  as they are displayed. That is, a large number of bubbles  131  generated below the lower liquid crystal display  4  appear from the bottom of the display  4 , rise gradually and then are displayed covering only the entire lower liquid crystal display  4  (see  FIG. 18 ). Continuously, the large number of bubbles  131  rise gradually and are displayed over both the upper part of the lower liquid crystal display  4  and the lower part of the upper liquid crystal display  3  (see  FIG. 19 ), and then rise further and are displayed only on the upper liquid crystal display  3  (see  FIG. 20 ). The number of bubbles that are shifted from the lower liquid crystal display  4  to the upper liquid crystal display  3  may be small, medium, or large (in any one of the three states) in this embodiment. The number of bubbles  131  is determined according to the image pattern selected in the above S 33 .  
      In this particular embodiment, a distribution of bubble sizes is predetermined as shown in FIGS.  18  to  20 . However, the size of each bubble as well as the distribution of the bubble sizes can be varied in accordance with the present invention. In such a case, selectable image patterns could be big bubbles, medium bubbles, and small bubbles of the same number. Further, any item other than the bubbles can be utilized.  
      Then, as shown in  FIG. 20 , when the large number of bubbles  131  are shifted and displayed above the payout table  123  on the upper liquid crystal display  3 , the payout change information (a multiplier thereof) selected in the above S 33  is displayed so that the information is superposed on all or a part of the payout table  123 , as shown, for example, in  FIG. 1, 21  or  22 .  
      In this respect, as shown in  FIG. 1 , the payout change information of “×2” for doubling the payout of the payout table  122  of ‘LINE’ odds is selected in the above S 33 . Therefore, when the large number of bubbles  131  are shifted and displayed above the payout table  123  on the upper liquid crystal display  3 , a translucent half-tone dot mesh covers the entire payout table  122  of ‘LINE’ odds, and a character of “×2” is displayed overlapping the payout table  122  of ‘LINE’ odds.  
      In the case shown in  FIG. 21 , the payout change information of “×3” for tripling the payout of the payout table  121  of ‘ANY’ odds is selected in the above S 33 . Therefore, when the large number of bubbles  131  are shifted and displayed above the payout table  123  on the upper liquid crystal display  3 , a translucent half tone dot mesh covers the entire payout table  121  of ‘ANY’ odds, and a character of “×3” is displayed overlapping the payout table  121  of ‘ANY’ odds.  
      In the case as shown in  FIG. 22 , the payout change information of “×5” for quintupling the payout of the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds is selected in the above S 33 . Therefore, when the large number of bubbles  131  are shifted and displayed above the payout table  123  on the upper liquid crystal display  3 , a translucent half tone dot mesh covers both the entire payout table  121  of ‘ANY’ odds and the entire payout table  122  of ‘LINE’ odds, and a character of “×5” is displayed overlapping the payout table  121  of ‘ANY’ odds and the payout table  122  of ‘LINE’ odds.  
      In any event, the payout change information (a multiplier thereof) selected in the above S 33  may be displayed in the midst of movement and display of the large number of bubbles  131  over the payout table  123  on the upper liquid crystal display  3 , as shown in  FIG. 19 , so that the information is superposed on all or part of the payout table  123 . In such a case, as long as the player keeps his eyes on the large number of bubbles  131  to be shifted from the lower liquid crystal display  4  to the upper liquid crystal display  3  as they are displayed, the player cannot miss the moment when the payout change information (a multiplier thereof) concerned is displayed so as to recognize the information.  
      Here, it appears to the player that the payout change information and the bubble effect performed in the effect image process in S 35  are displayed at the same time as the variable display of symbols on the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C (see  FIGS. 1, 21 , and  22 ) is started in the game (S 41  of  FIG. 15 ).  
      Thereafter, the program returns to the main process program of  FIG. 10 , and proceeds to game process of S 13 .  
      Next, the game process program executed in the slot machine  1  is explained with reference to  FIG. 15 , which shows a flowchart of the game process program. The game process is executed in S 13  of the main process program of  FIG. 10 . For that purpose, a rotation process is first executed in S 41  of  FIG. 15 . More specifically, in this rotation process, the video pictures of symbols which constitute the video reel  100  are scrolled from the right-to-left direction in each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C on the basis of the switch signal which is outputted from the spin switch  57 , the 1-BET switch  58 , the 3-BET switch  59 , the 5-BET switch  60 , or the 8-BET switch  61  and is received in S 11  of  FIG. 10 .  
      Then, a stop control process is executed in S 42 . More specifically, in this stop control process, the video reel  100  which is constituted of symbols is stopped so that each symbol determined on the basis of the lottery result in the symbol determination process of S 31  is displayed in each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C. Accordingly, each symbol is displayed statically.  
      Then, in S 43 , an equivalent amount of coins and the like to what is obtained by multiplying the payout set up in advance in the payout table  123  of  FIG. 9  by the multiplier of the payout change information displayed on the upper liquid crystal display  3  is paid out according to the winning combination of symbols having been stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 . When winning combinations are realized along a plurality of activated pay lines L 1  to L 8 , the payouts of the winning combinations are added together. Therefore, when a plurality of ‘ANY’ odds and a plurality of ‘LINE’ odds are realized simultaneously, for example, an equivalent amount of coins and the like to what is obtained by multiplying each payout of the odds of which payout change information is displayed on the upper liquid crystal display  3  by the multiplier of the concerned payout change information and then totalizing resultant individual payout amounts is paid out.  
      When the process of S 43  is executed, the main process program of  FIG. 10  comes to an end, and the main process program of  FIG. 10  is newly started.  
      Therefore, as mentioned above, when the CPU  50  executes the lottery process for changing the payout table in S 33  in the lottery process of  FIG. 12 , the CPU  50  functions as “payout change lottery means”.  
      Moreover, when the CPU  50  executes the effect image process in S 35  in the lottery process of  FIG. 12 , the CPU  50  functions as “first means for shifting and displaying images”.  
      As explained in detail above, when the payout change information (any one of “×2”, “×3”, “×4” and “×5” here) which changes the payout of the payout table  123  is selected (S 33 ) in the slot machine  1  of the present embodiment, the selected payout change information is, as shown in  FIGS. 1, 21  and  22 , displayed overlapped on the payout table  123  on the upper liquid crystal display  3  (S 35 ) at the start of the game. Such payout change information is delivered to the player securely by guiding the player to keep his eyes on the large number of bubbles  131  in the bubble effect displayed in the order as shown in FIGS.  18  to  20  (S 35 ), that is, with the large number of bubbles  131  in the bubble effect shifted from the lower liquid crystal display  4  on which the player focuses his attention to the upper liquid crystal display  3  on which the payout table  123  is displayed (S 35 ) since the lower liquid crystal display  4  displays the game result as each symbol is stopped and displayed statically in each of the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C. Therefore, the player may experience a sense of freshness at the game start since the game player can recognize various kinds of payout change information when the player plays the game, and may be prevented from feeling monotony of the game which uses the payout table  123 .  
      The payout change information (here any one of “×2”, “×3”, “×4” and “×5”) which changes the payout of the payout table  123  in the game can further attract the interest of the player since the information signifies, whichever information is selected, increase of the payout of payout table  123  by a predetermined multiplication factor (here twice, three times, four times, or five times) (see  FIG. 13 ) and is advantageous to the player.  
      The present invention is not limited to the above embodiments, and various modifications may be made within the scope of the present invention without departing from the spirit of the present invention.  
      For example, an opportunity to perform the lottery of payout change information and the lottery of bubble effect (S 33 ) is limited only to an occasion in which one or more winning combinations of symbols are stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 . When no winning combination of symbols is stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 , the latest lottery result among the already-performed lottery results may be used instead without making the lottery of payout change information or the lottery of bubble effect.  
      Further, when no winning combination of symbols is stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 , only the bubble effect of shifting a large number of bubbles  131  from the lower liquid crystal display  4  to the upper liquid crystal display  3  as they are displayed may be performed without displaying the payout change information in the game concerned.  
      That is, in such a case, for example, the program proceeds from the lottery process of S 33  of  FIG. 12  to the flowchart shown in  FIG. 16 . Then, in the flowchart shown in  FIG. 16 , S 101  is first executed, in which it is determined whether the payout table is to be changed. If any winning combinations of symbols are stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 , it is determined to change the payout table. If no winning combinations of symbols are stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 , it is determined that no change is made in the payout table. Here, if it is determined that the payout table is changed (S 101 : YES), the lottery process of S 34  of  FIG. 12  is executed. On the other hand, if it is determined that no change is made in the payout table (S 101 : NO), the program proceeds to S 102 , and no payout change information is displayed at all, but only the bubble effect is performed in which the large number of bubbles  131  are shifted from the lower liquid crystal display  4  to the upper liquid crystal display as they are displayed. Thereafter, the process returns to the main process program of  FIG. 10 .  
      The determination in the above S 101  may be made only by means of a random number lottery regardless of whether a winning combination of symbols is stopped and displayed statically or not. Even in this case, the payout change information may be displayed or may not be displayed depending simply on the result of the random number lottery when the bubble effect is performed in which the large number of bubbles  131  are shifted from the lower liquid crystal display  4  to the upper liquid crystal display  3  as they are displayed. As mentioned above, it is determined by the random number lottery that the payout change information is displayed or not, regardless of whether the winning combination is stopped and displayed statically or not.  
      Therefore, as mentioned above, when the CPU  50  executes the determination process of S 101  of  FIG. 16 , the CPU  50  functions as “execution lottery means”.  
      Alternatively, when the CPU  50  executes the effect image process of S 102  of  FIG. 16 , the CPU  50  functions as “second means for shifting and displaying images”.  
      As to the image pattern of the bubble effect, candidate patterns to be selected may be limited in advance and assigned to respective winning combinations to be stopped and displayed statically in the variable display parts  22 A to  22 C,  23 A to  23 C and  24 A to  24 C along the activated pay lines L 1  to L 8  displayed on the lower liquid crystal display  4 . Or only one image pattern may be set up in advance.  
      Moreover, when the selected payout change information (here, any one of “×2”, “×3”, “×4” and “×5”) is displayed, the payout of the payout table  123  may be rewritten to a value which is increased by the predetermined multiplication factor (here, any of twice, three times, four times, and five times) of the payout change information concerned and displayed on the upper liquid crystal display  3 . Further, only the payout of the predetermined winning combination in the payout table  123  may be increased in such a rewriting process.  
      The lottery result of the payout change information and the lottery result of the bubble effect may be continuously utilized over several consecutive games.  
      The examples of changes as mentioned above may be applied to the slot machine  1  of the present embodiment in combination.  
      The present invention may apply to the technology of changing payout tables in a game to be performed with a gaming machine.  
      As described above, by way of example, the following gaming machines may be included according to the present invention.  
      According to the present invention, a gaming machine (e.g., slot machine  1 ) is provided. The gaming machine comprises: a first display (e.g., lower liquid crystal display  4 ) for displaying a result of a game; a second display (e.g., upper liquid crystal display  3 ) provided next to the first display (e.g., lower liquid crystal display  4 ), the second display displaying a payout table of the game; payout change lottery means (e.g., CPU  50 , S 33 ) for conducting a lottery to select one piece of payout change information from a plurality of pieces of payout change information for changing payout of the payout table displayed on the second display (e.g., upper liquid crystal display  3 ); payout change display means (e.g., CPU  50 , S 35 ) for displaying the one piece of payout change information selected by the payout change lottery means (e.g., CPU  50 , S 33 ) on the second display (e.g., upper liquid crystal display  3 ) at game start; and first image shift means (e.g., CPU  50 , S 35 ) for shifting a payout change notification image from the first display (e.g., lower liquid crystal display  4 ) to the second display (e.g., upper liquid crystal display  3 ) when the one piece of payout change information is displayed on the second display (e.g., upper liquid crystal display  3 ) by means of the payout change display means (e.g., CPU  50 , S 35 ) at the game start.
