Cast Ring

Previously the Eureka Ring Puzzle. The Cast Ring is based on a 15th century European puzzle, and this style was actually used for official engagement rings. This version is approximately 5cm in diameter, and so is not a piece of jewellery, but a quite tricky coffee table puzzle!

Difficulty level 4
