A very interesting 3x3x3 cube with only 1 solution. Designed by Stewart Coffin in 1975 who said that a half hour would be a good solution time, but it takes up to two hours for most! This puzzle is very nicely made from Creative Crafthouse's shop and a first glance looks like a Soma Cube. But whereas a Soma has 240 possible cube solutions, this has only 1. Comes with attractive base and cover.
Dimensions: 2.5" x 2.5" x 2.5"
Difficulty level: 4 (out of 6)
Suggested age: 10+
Fun to solve again and again! Solid wooden pieces. Will last for years.
I took this one apart - the name is a lie LOL! it's STILL apart! very fun to play with - pieces are smooth enough you don't have to worry about splinters. I enjoy the Soma cube more - it's a bit easier though still challenges me!
