product description:
Small parts. Not for children under 6 yrs.
A disentanglement puzzle is a type of mechanical puzzle that involves disentangling one piece or set of pieces from another piece or set of pieces. The reverse problem of reassembling the puzzle can be as hard as-or even harder than-disentanglement. There are several different kinds of disentanglement puzzles, though a single puzzle may incorporate several of these features.
The Chinese Rings Puzzle and Nine Chain Puzzle Toy is believed to be one of the oldest puzzles known, dating back to China over 2000 years ago. We believe that what makes it so popular is that it cleverly combines both logic and creative thinking.
