Zig-Zag Knot

This “cousin” of the best-selling Gordian’s Knot is designed to be elegant but cunning. Untangling Zig-Zag Knot is not as easy as it looks. The player slides each piece in the correct sequence of 37 moves to take the Zig-Zag Knot apart. With every move made, one or more pieces will move easily, but there’s only one right answer. The included guide shows the complete solution as well as full instructions for putting Zig-Zag Knot back to its original form. Launch date: April 2010.
