Casse tête en metal de la série Cast Puzzle et de difficulté niveau 5 (sur une échelle de 6).
Description éditeur en anglais:
This is the second of the ring puzzles. The five separate rings can be taken apart and put back together. This version has been changed a bit from the original made by connecticut's Jose Grant. This puzzle has five rings, like the Olympic rings that stand the test of time. That is the basic concept behind this puzzle. This type of ring puzzle goes back at least as far as the 15th century, and is now remade with today's puzzle crafting knowledge.
Give it a go.
