GAME MACHINE

PROBLEM TO BE SOLVED: To enable changing of rendering at free timing without needing to prepare a plurality of rendering patterns beforehand, in a game machine provided with an operating switch (a rendering button) operable by a player and configured to change rendering contents according to the operation of the operating switch.SOLUTION: A rendering control device (300) includes a valid period control means for controlling change between an operation valid period in which operaton on an operating means (25) is valid and an operation invalid period in which the operation is invalid; an operation detecting means (25a) detecting the operaton on the operating means in the operation valid period; and a rendering content changing means capable of changing normal rendering carried out in a variable display game to special rendering according to predetermined conditions. When the operaton on the operating means is detected by the operation detecting means during the operation of the rendering content changing means, the rendering content changing means is configured to carry out the special rendering after carrying out correction rendering for time adjustment triggered by the detection of the operaton on the operating means.
