The game has set up a wide variety of rich and diverse scene levels, covering many themes. For example, in the fairy tale world scene, there are lovely elves, dreamy castles and mysterious magic forests. There are also historical and ancient site scenes, presenting ancient temples, mottled city walls and stone statues of various shapes. In addition, like daily life scenes, it includes warm home furnishings, lively vegetable markets and busy streets. Each level provides two pictures that look almost exactly the same. The player's task is to find out those subtle differences. Only by finding all the differences can the player successfully pass the level.
