Hanayama Cast Puzzles are well-crafted metal puzzles that stand out not only for their exceptional quality but also for their extraordinary and high-quality design. The name 'Cast Puzzle' comes from the English word to cast, which means to mold metal.

The challenge of this intricate metal puzzle is to separate the pieces and then reassemble them. This is the second of the "Ring" puzzles. The five individual rings can be taken apart and put back together. This version has been slightly modified from the original by Jose Grant from Connecticut. This puzzle features five rings, like the Olympic rings, that stand the test of time. That is the basic concept of this puzzle. This type of ring puzzle dates back at least to the 15th century and is now being reissued with modern technology. Give it a try.
