PROBLEM TO BE SOLVED: To provide a pachinko machine which achieves a lowering of production costs by easily adapting a control circuit on a main substrate for the production of a pachinko machine having the new contents of game while reducing the burden on a control circuit. SOLUTION: A pachinko machine 1 is provided with a main substrate 43, a lamp substrate 44b and the like. The control circuit of the main substrate 43 outputs a control signal to a lamp lighting circuit of a lamp substrate 44b. The lamp substrate 44b is provided with a CPU 86A and a detachable type ROM 86B for storing lighting data of lamps W3 and W5 for the pachinko machine. The CPU 86A of a lamp lighting circuit into which is inputted a control signal from the substrate 43 reads out the lighting data stored in the detachable type ROM 86B to control the lighting of the lamps W3 and W5 for the pachinko machine. The replacement of the detachable type ROM 86B enables switching over to a new flashing cycle of the display lamps W3 and W5.
