This puzzle is called "456" because two of the sides have four squares, two of the sides have five squares, and two of the sides have six squares. There are 15 wood pieces in total; the objective is to disassemble the pieces and then reassemble them into their original configuration. The irregular number of pieces makes the 456 an interesting variation on the traditional burr-type puzzle.
