PROBLEM TO BE SOLVED: To provide a pinball game machine full of excitement and enjoyment by making games tricky. SOLUTION: A start pocket device 16 is provided in a playing area. The start pocket device 16 is made up of a winning pocket 22 and a bank path 24 provided below a ball outlet 28 of the winning pocket 22. The ball outlet 28 is made larger than the diameter of the Pachinko ball 13. The bank path 24 (downflow surface 32) is made spiral about the center axis C and the downflow surface 32 is declined toward the center axis C. First to third start winning sensors 26a-26c are disposed along the bank path 24. When Pachinko balls 13 pass through the start winning sensors 26a to 26c, an electronic lottery is carried out. The dropping position of the Pachinko balls 13 to the downflow surface 32 varies to cause changes in the frequency of the electronic lottery. This makes the games tricky, thereby enhancing the excitement and enjoyment in games. COPYRIGHT: (C)2008,JPO&INPIT
