PROBLEM TO BE SOLVED: To provide a Pachinko game machine referred to as Hanemono (wing type machine), which has a substantially constant probability of flowing of a game ball into a specific area regardless of the timing in which the game ball wins a prize at a variable prize winning device. SOLUTION: The inside of the variable prize winning device 4 is provided with a first flow passage 82, and the inside of the first flow passage 82 is provided with two upper and lower first and second game ball-detecting sensors 84 and 85. A specific area 43 and general areas 44 are provided below a bottom 86 in the variable prize winning device 4. Above the areas, a distribution member 45 is provided which is switched between a first state where the game ball is guided to the specific area 43 and a second state where the game ball is guided to a general area 44. Based on the passing time in which the game ball passes through the first and second game ball-detecting sensors 84 and 85, a variation time required from detection by the second game ball-detecting sensor 85 to switching of the distribution member 45 from the second state to the first state is calculated.
