These puzzles are traditionally made of wood, but versions made of plastic or metal can also be found.

It is not exactly known where and when the burr puzzles were created. Throughout history, in China wooden structures and furniture were made without the use of fasteners and glue. In these constructions, the structural elements were tied to each other by woodworking joints. There is a great similarity between the design of burr puzzles and traditional Chinese joinery and probably the burr puzzles were inspired by similar carpenter’s techniques.
