Cast Helix

Cast Helix Note: Our level rating system is different than Hanayama’s.  Hanayama’s level 1 is equivalent to our level 5…. level 6 is equivalent to our level 10. 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 goal of this puzzle is to remove the helix ring that goes through that hole. 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. The theme of this puzzle is “Flower.” Designed by: Akio Yamamoto 2009

Remove the ring.

The first thing you see when you look at a puzzle is the photo or illustration of the finished puzzle. When choosing, keep in mind that the image must have an educational value, but also something that the child can identify with. If the image is familiar to the child or meets the educational purpose (such as learning colors or name objects), the experience of completing the puzzle will be more enjoyable, satisfying and productive. The image must be easily recognizable so that the child can recognize it as something that they see around them in their daily lives. It must also distinguish functions to help them decide where to place the piece so that it is placed in the right place
