Kupi Hanayama Cast Helix Puzzle

The Hanayama range has been painstakingly designed and developed over more than a quater of a century and is quite simply the most inspiring collection of puzzles ever created!

Puzzle Mission - Separate the ring from the star and put it back again. The grooves engraved in the two rotating boards are called "logarithmic spirals." These two grooves always cross at right angles, and a square hole is formed at their intersection. The inspiration of this puzzle is the morning glory. The puzzle was designed to look like a bud that comes into bloom with twining tendrils. The original concept dates back to 1990, but it has been enhanced with the addition of several tricky features. These puzzles are hopelessly addictive and are arguably the most collectable puzzles on the planet.
