简单有趣,但充满挑战的游戏。翻转瓷砖,直到它们全部变白。
Click any tile to reverse it's color and the color of it's adjacent tiles. Keep flipping tiles until you gotten them all to be white. Sounds easy but it's very challenging. Two levels: easy (3x3) where the tile you click and the ones on each side of it flip, and hard (4x4) where the tile you flip and the ones on each side and corner of it flip.
