Tangram is a digital conversion of the traditional Chinese puzzle game of the same name.
Using a set of seven shapes (two large, one medium, one small triangle, one square and a parallelogram) the player is tasked with recreating various two dimensional figures. The player is only given a silhouette of the figure and has to figure out the position of each piece. All figures use all pieces.
The game has five difficulty levels and features a free form where you can design your own figures. You rotate the individual shapes with the cursor and can ask for hints.
