A game machine includes a predetermined number of playing balls; a game board provided with a playfield on which the playing balls cascade downward; a launching device configured to launch the playing balls toward the playfield; a supply part configured to supply the playing balls to the launching device; a collecting part configured to collect the playing balls supplied from the supply part to the launching device and launched to the playfield; and a guide part configured to guide the playing balls collected by the collecting part to return to the supply part without discharging the playing balls outside the game machine. The predetermined number of playing balls circulate through the game board, the collecting part, the guide part and the supply part, and can be repeatedly used.
