Tetra- and Pentatwig Puzzles
These puzzles use the 4 tetratwigs and 12 pentatwigs. The pieces cover 76 unit line segments.
Geometric Forms
Use all pieces to make a symmetric pattern. Here are examples for the different types of symmetry. Click the images below to see example puzzles and solutions. Type of Symmetry
Double Bilateral Horizontal Vertical Birotary
Pairs
Use all the pieces to make two identical copies of a pattern. Pairs can be assembled to form a single symmetric figure, with the exception of horizontally symmetric pairs, which cannot be connected. Here are examples for the different types of symmetry. Click the images below to see example puzzles and solutions. Type of Symmetry
Double Bilateral Horizontal Vertical Birotary Quadruplets
Use all the pieces to make four identical copies of a pattern.
More Geometric Forms

Full Sextarotary Ternary & Horizontal Ternary & Vertical Trirotary Double Bilateral Horizontal Vertical Birotary Triplets
Leave out one of the tetratwigs and use the other pieces to make three copies of a pattern, covering 72 unit line segments. The three pieces can be combined to form a single symmetric shape.
