Seven Tans is the classic Chinese game of Tangram, also known in China as 七巧板 or the "Seven Boards of Skill".

The objective of the puzzle is to form a given shape given only it's silhouette. You must use all seven of the provided pieces, called tans. The seven tans must not overlap within the shape's silhouette.
