The invention provides a game device used for properly evaluating touch operation of corresponding marks; a mark display control portion allows the touch panel to display hit marks inputted by operation input order and instruction hit operations, and allows the touch panel to display a sweep operation instruction mark inputted by the instruction sweep operation, i.e., the sweep operation instruction mark can indicate operation input time, position and sweep direction; a touch operation detection portion (208) can detect the sweep operation corresponding to the sweep operation instruction mark; when the sweep operation input of corresponding sweep operation instruction mark is detected, an operation invalid zone setting portion (210) can temporarily set the operation invalid zone; in the operation invalid zone setting period, the touch operation in the operation invalid zone can be selected from evaluating objects for commenting.
