This puzzle is an expanded version of the Meanders Box. In the
Meanders Box, the top plate slid along with the four side pieces. In the
Dual Meanders Box, not only does the top plate slide, but the bottom
plate also slides. This allows for a puzzle with a large number of moves
without the need to increase the steps of the side pieces.This
puzzle can be configured to 4 different positions based on the
orientation of the 2 plates, which move counts being 325, 367, 410, and
506 moves....
