Match pairs of identical tiles to remove them from the board until it's entirely cleared or until you find all special tiles. You can only match tiles which are free on at least one side. Match as fast as you can to earn awards and medals to unlock more levels. Season tiles match even if the picture is different. The same works with flower tiles. Rock tiles don't do anything. Some tiles are reversed, they turn around as you select them. To free trapped tiles, you have to match scissors.
