PROBLEM TO BE SOLVED: To realize a game winning a prize adding a high game value with high probability according to points. SOLUTION: On the basis of a table constructed so that a first prize group, to which a prize giving a high game value belongs, is won with a high probability, an internal lottery is carried out for each game. The sequence for stopping respective rows is decided by a lottery. The prize in the first prize group is won when the first prize group is won by the internal lottery, the sequence for stopping the rows corresponds to the sequence of stopping operation of a player, and a combination of the generator patterns matching the first prize group is arranged on an effective prize row. If the stopping sequence is different from the sequence of the stopping operation of the respective rows by the player, or if the combination of generator patterns matching the first prize group is not arranged on the effective prize row though the stopping sequence corresponds to the sequence of the row stopping operation by the player, the prize in the first prize group is not won, and a prize allowable condition for the first prize group is deleted after the game is finished.
