To provide a game, which a player can enjoy while watching the pattern fluctuation to the last, by forming three special pattern display units capable of being recognized by the player, and fluctuating patterns of two of these three special pattern display units so as to combine preset patterns of the special patterns or non-special patterns.

In a process after getting a reach, when a game ball wins a usual electric generator 57, pattern of special pattern display units L1-L3 are fluctuated at the same time, and after the predetermined time is passed, a pattern of the special pattern display unit L1 is temporarily stopped, and displays two patterns of A at an upper part and 3 in a lower part. The special pattern display unit L3 of a second group displays a definite pattern 2 at a central part so that the player can recognize it (B), and thereafter, a pattern of the special pattern display unit L2 of a first group is fluctuated upward or downward by a half-pattern. A definite pattern A, 2, A formed by the downward fluctuation (C) and a definite pattern 3, 2, 3 by the upward fluctuation (D) means a miss.
