The Ptarmigan Three Layer Puzzle
is a three layer jigsaw puzzle
but with an extra twist.
Each piece in one layer is linked to a piece in another layer but allowing the two halves to be rotated freely
The Ptarmigan Three Layer Puzzle consists of 8 linked pairs of pieces
, and a base board.
The pieces stack when placed within the base board to fill three layers - the top and bottom layers both being square and the middle layer in a cross shape.
This is a much simpler cousin of the Ptarmigan Puzzle which can be found here
