Tri- and Tetrawave Puzzles
These puzzles use the 13 tetrawaves and the four triwaves. The pieces cover an area of 64 units.
Geometric Forms
Use all the pieces to make a symmetric pattern. Here are examples for the different types of symmetry. If the pieces are confined to the grid, true symmetry is impossible in the vertical axis. However, if the pieces are regarded as distorted squares, then we can treat a pattern as symmetric if the equivalent polyomino construction is. Type of Symmetry
Full Tetrarotary Double Bilateral Reflective Double Diagonal Diagonal Birotary
Tetromino Replicas
Approximate replicas can be constructed for each of the five tetrominos.
