Chained Square has 16 squares that are connected with ball style chain, which gives it great flexibility. The goal is to fold the pieces into a 4x4 square. Each piece that has a letter on it is connected by 3 chains - the pieces without letters have only 2 chains connected. The puzzle is difficult because of the tetrahedral topology of the weave pattern, and the lack of "simple conventional" solutions. The frame was included so that the puzzle can be stored and displayed!
