CHALLENGE: Separate the sword (the long stud) from the rings.

Difficulty: INCREDIBLE 5/6. Average solution time: 1 hour - 1 year.

This is the most difficult metal brain teaser ever made!

The solutions is an extremely difficult sequence of steps like in Rubik's Cube: minimum 511 steps! The maximum quantity of steps has no limit, because it depends totally on your logic ability.

This brain teaser is a great classic in Chinese culture, invented hundreds years ago. The nine linked rings, which are also called Chinese rings, is perhaps Chinese greatest mechanical puzzle. 

Long analyzed by mathematicians, and now also by computer scientists, the puzzle consists of a looped handle that is interlocked with nine rings.

Dimensions: 19 x 1 x 7 cm / 7.5 x 0.4 x 2.7 inches.

BOX dimensions: 21 x 2 x 10 cm / 8.3 x 0.8 x 3.9 inches.
