To provide a game machine and simulation program in which a player is effectively made to pay attention to an ornamental image and interest in a game can be raised.

A Pachinko game machine 10 performs display control for a variable indication of an identification pattern with an ornamental image added in a plurality of pattern lines. As to a first specific identification pattern which is derived and displayed in accordance with a left line, and a second specific identification pattern which is derived and displayed and combined with the first specific identification pattern to comprise a specific display mode, the Pachinko game machine 10 determines the display mode of the ornamental image added to the first specific identification pattern and the second specific identification pattern to be a particular display mode, and determines the display mode of the ornamental image added to any identification pattern which corresponds to middle and right lines, other than the second specific identification pattern into a non-particular display mode other than the particular display mode.
