About Tangram
An implementation of the Tangram — a tiling puzzle consisting of
seven polygons (five triangles in three sizes, a square, and a
parallelogram) that can be put together to form shapes. Includes a
number of puzzles that the player can try to solve, or the player can
sketch out their own shapes.
Runs on Android 6 (Marshmallow) through 17 (Cinnamon Bun) and up.
