PROBLEM TO BE SOLVED: To provide a pachinko island machine wherein a ball lifting device can be operated in a stable manner for a long period of time by preventing balls fed from another pachinko island machine from excessively flowing in. SOLUTION: An overflow passage 61 and a suction passage 62 are provided so as to be adjacent to each other and the lower portions of both the passage are joined together so as to communicate with a lower storage tank 13 at a joining portion 64 of the passages 61, 62, whereby a preferentially guiding structure is formed so that balls guided by the passage 61 are guided to the tank 13 preceding balls guided by the passage 62. Hence when the interior of a pachinko island machine is filled with balls, balls flowing out of upper tanks 41, 49 are filled fully into the downstream end portion of the passage 61 so that balls from another pachinko island machine, fed from the passage 62, are prevented from flowing into the tank 13.
