On the display  9  of each machine, a symbol (star, triangle, circle or X) is displayed. 
     When a roulette game is started, the roulette  4  spins and the ball stops at any position of the inner frame  26 . The symbol shown in an inner frame that is adjacent to the middle frame where the ball is stopped is a winning symbol. Then, the award is paid out at the gaming machine displaying the winning symbol. For example, since the selection unit  28  (the ball) has stopped at the position selecting the symbol star in  FIG. 3 , the star is the winning symbol and the award is paid out at the gaming machine  20 . Three stars exist, thus the winning ratio of the star is 3/8. 
     The style of the secondary game pertaining to the present invention is not limited to those described above. For example, the roulette  4  may have frames other than the outer frame  25 , the middle frame  26 , and the inner frame  27 . The roulette  4  may have, for example, four frames and any one of the outer frame, the middle frame or the inner frame may exist two.

The color may be any color, and it may be, for example, a mixture of a plurality of colors. The number may be any number, and it may be, for example, a number of two or more digits or a decorated number. 
     The selection unit  28  may be in any form, and it may be, for example, a ball, an arrow or a star. The selection unit  28  may not need to move, for example, the roulette  4  may spin against the fixed selection unit  28  and choose any symbol on the roulette. The selection unit  28  may not need to be one, and it may be in plural. And a plurality of the selection units  28  may choose a plurality of symbols. For example, two symbols may be chosen by throwing two balls on the roulette in order. Further, two symbols may be chosen by fixing two arrows and rotating the roulette. The timing for choosing the symbols with a plurality of the selection unit may or may not be at the same time. 
     Also, the shape of the roulette is not limited to a circular form, and it may be in any shape. For example, the roulette may have a triangle or a square shape and spin. Also, the number of the roulette is not limited to one, and there may be a plurality of roulettes. In a case when a plurality of the roulettes exists, each roulette may select one symbol, or each roulette may select a plurality of symbols. Further, the number of frames provided on the roulette is not limited, and it may be any number. For example, the outer frame of the roulette may consist of 36 frames or 4 frames. And, the middle frame of the roulette may consist of 4 frames or 16 frames, instead of 8 frames. 
     The symbol for specifying the gaming machine may be decided at the beginning of the secondary game, decided beforehand, or decided at any time. For example, the machine number may be the symbol. The symbol for specifying the gaming machine is not limited to be displayed on the display  9 . It may be displayed on any part, such as the display  8 . Further, it may be configured such that the symbol is not displayed on the gaming machine but the player can recognize the symbol, which represents himself or herself.

Further, the number printed on the machine main body may be displayed on the roulette as a symbol. 
     In addition to those described above, for example, each award amount of a progressive may be displayed on the roulette in a case of the progressive game. For example, each award amount of a progressive is displayed on each of the middle frame  26 , and the selection unit  28  stops at a progressive award amount with a symbol. Then, the machine corresponding to the symbol may be able to receive the progressive award. Further, a game mode may be displayed on the roulette. In such case, for example, the machine selected by the selection unit  28  may start a bonus game with selected game mode. Also, a display indicating a jackpot is provided on the roulette and in a case when the selection unit  28  has selected the jackpot, the jackpot may be paid out at the selected machine. Further, the number of times of game may be displayed on the roulette. In such case, for example, a number of times of free game corresponding to the selected number of times of game may be started on the machine selected by the selection unit  28 . 
     Also, the symbol displayed in the frame on the roulette may indicate losing instead of winning. For example, in  FIG. 3 , out of 8 frames of the inner frame  27 , some frames may display a losing symbol. In a case when the selection unit  28  has selected a losing symbol, the player may not be able to proceed into the secondary game. 
     Further, among a plurality of the gaming machines, not all of the machines need to proceed into the secondary game. For example, four machines are performing the primary game, and one or two machines out of those machines may proceed into the secondary game. In such case, for example, the symbols displayed on the 8 frames of the inner frame  27  may only display the machines, which have proceeded into the secondary game. Further, the symbols indicating losing may be included in these symbols.

When the secondary game is determined not to have completed, a determination is made as to whether to adjust the game condition of the secondary game again or not (Step  12 ). When the game condition needs to be adjusted again, the secondary game resumes after adjusting the game condition (Step  4 ). When there is no need for the game condition to be adjusted again, the secondary game resumes according to the original setting without the adjustment of the game condition (Step  7 ). 
     When the secondary game is determined to have been completed, a determination is made as to whether the entire game has been completed or not (Step  13 ). When the entire game is determined not to have been completed, the primary game is started again (Step  1 ). When the entire game is determined to have been completed, the game ends (Step  14 ). 
       FIG. 12  illustrates a flow chart of the tournament play. In a game system of the present invention, first, the primary game is started (Step  1 ). After the primary game is started, a drawing is performed in regards to the transition to the secondary game (Step  2 ). As a result of the drawing, a determination is made as to whether there was a winning to proceed into the secondary game or not (Step  3 ). When determined that there was the winning to proceed into the secondary game, a transition is made from the primary game to the secondary game (Step  4 ). When determined that there was no winning to proceed into the secondary game, the primary game is started again (Step  1 ). 
     When there is the transition to the secondary game (Step  4 ), the form of the symbols shown on the secondary roulette (Step  5 ), the combination of the tournament (Step  6 ), and the winning odds of the machine (Step  7 ) are decided. The order of the decisions of the winning odds, the combination of the tournament, and the form of the symbols, may be in reverse order. Thereafter, the secondary game is started (Step  8 ). After the secondary game is started, a winning machine is decided in the secondary game (Step  9 ). And a determination is made as to whether the number of the winning machine is one or not (Step  10 ). In a case when a plurality of the winning machines still exists instead of one winning machine, the combination is rearranged among the winning machines and the tournament is created. Then, in order to decide one winner, the secondary game is started again (Step  8 ). Meanwhile, the number of the winning machine is determined to be one, an award amount for the winning machine is decided (Step  12 ), and the award amount is paid out to the winning machine (Step  13 ). 
     In addition, the system may be configured to payout the award to a plurality of the winning machines in a case when a plurality of the winning machines exists in Step  10 . Further, the combination of the tournament is arranged again in the Step  11 , however, the game may be proceeded according to the original tournament without changing the combination. 
     When the award amount is paid out to the winning machine (Step  13 ), a determination is made as to whether the secondary game is completed or not (Step  14 ). When the secondary game is determined to have not completed, a determination is made as to whether to adjust the game condition of the secondary game again or not (Step  15 ). In a case when the game condition needs to be adjusted again, the secondary game resumes after adjusting the game condition (Step  4 ). In a case when the game condition does not need to be adjusted again, the secondary game resumes according to the original setting without adjusting the game condition (Step  8 ). 
     When the secondary game is determined to have completed, a determination is made as to whether the entire game has completed or not (Step  16 ). In a case when the entire game is determined not to have completed, the primary game is started again (Step  1 ). In a case when the entire game is determined to have completed, the game ends (Step  17 ).
