Patent ID: 8047906

Claim:
A game machine, which allows a player to execute a game operation using a controller in time with game music, the game machine comprising a processor which runs a program capable of performing the functions of: obtaining timing of the game operation executed using the controller; storing timing data, the timing data indicating when to execute the game operation using the controller; displaying, on a display screen, a timing instruction image to guide the player about when to execute the game operation; displaying, on the display screen, a timing guide image, said timing guide image including a normal timing guide and a special timing guide for said player, to guide the player about when to execute the game operation, the special timing guide being created based on the stored timing data, the special timing guide gradually approaching the timing instruction image, wherein said special timing guide has an appearance that is substantially different from said normal timing guide; evaluating the game operation executed by the player by comparing the timing of the obtained game operation timing with timing represented by the stored timing data that the special timing guide is created from, to generate a time gap; and changing a display position trajectory of the special timing guide on the display screen when the time gap is smaller than a given amount, so as to inform said player of said evaluating each time the game operation is executed, wherein when the evaluation result is less than a predetermined time, the display position trajectory of the special timing guide is changed, so that the special timing guide turns from an initial trajectory having an initial direction to a special trajectory having a different direction from the initial direction, to collide with the normal timing guide and to cause the normal timing guide to disappear, and the player is no longer required to execute the game operation indicated by the normal timing guide.
