Cast Helix represents channels engraved in the two rotating parts called “logarithmic spirals.” These two channels always intersect at right angles, and a square-shaped hole is formed at their intersection. The goal of this puzzle is to disassemble the helix ring that passes through that hole. The inspiration for this puzzle is morning glory. The puzzle was designed to symbolise a bud blooming. The original concept dates back to 1990, but it has been improved to have a greater degree of circulation.
