Gameplay
Both the top screen and the touch screen show a picture. They are identical at first glance, but the picture on the touch screen includes a difference. The player has to find and tap the difference.
 * 1st level difficulty: The difference involves the central person in the picture.
 * 2nd level difficulty: The difference involves a noticeable background element (e.g. clock hands, wanted poster, bush, canvas).
 * 3rd level difficulty: The difference involves a small background element (e.g. kanji on a sign, roof shape) or a subtle change in the central person.
