<p>A game machine in which the development of rendering can be quickly performed and the variation of rendering can be widened. A ROM (81) of a rendering control board (80) stores rendering drawing tables for respective rendering modes in each of which the drawing probability of determining the rendering contents and the drawing flags is determined for each result of the internal drawing. The drawing flags includes flags indicating the types of rendering and rendering mode change flags. A CPU (85) of the rendering control board (80) performs rendering drawing by using the rendering drawing table of the current rendering mode according to a rendering command sent from again control board (70). On acquiring a rendering mode change flag as a drawing flag as a result of the rendering drawing, the CPU (85) changes the rendering mode of the current game from the current one to another predetermined one and again performs a rendering drawing by using the rendering drawing table for the another rendering mode.</p>
