The player, in each level, must spot the 6 differences between the two pictures before time runs out. Clicking on a bad spot results in a 30 seconds penalty. If time runs out, a life is lost. If all lives are lost the game is over. The game features 7 different levels that appear in random order.

Game is completely controlled by mouse. Press +/- to enable/disable sound. Press ESC to quit to the main menu.
