Though inspired by a budding Morning Glory, "Helix" is no gentle flower. The twining tendrils of this puzzle feature engraved grooves on two rotating spirals. The grooves cross at right angles, creating square holes at their intersection points. Can you bring this bud to bloom and free the helix ring? Designed by Akio Yamamoto.
