Tangram Animals

Compose an original animal silhouette from polygon pieces, reasoning about turns, reflections and complete coverage.

How to play

Choose a piece, turn it and choose a snap spot. Place it with a button, tap the board or drag its handle. Flip appears only when that piece may be reflected. Show guides is always available.

Edges may touch, but pieces cannot overlap or leave gaps. Identical triangles can trade places, and any geometrically complete arrangement counts. Undo and Reset keep discoveries; Next animal waits for you.
