PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing the decline of game amusement in a game machine set so that roles achieved by a plurality of start ports are different. SOLUTION: While a first start port sensor 2416 is attached on the side of a winning space forming cover body 621, a second start port sensor 2358 is attached on the side of a ball entrance unit 1402. That is, they are disposed such that a distance from the entry of a game ball to a second start port 1421 to the detection of the game ball by the second start port sensor 2358 is shorter than a distance from the entry of a game ball to a first start port 1420 to the detection of the game ball by the first start port sensor 2416. Thus, as the result of preferentially detecting the game ball by the second start port sensor 2358 so as to expect the generation of a big winning for increasing the expected value of the number of game balls, since a player becomes advantageous even a little, the decline of the game amusement is suppressed.
