Half Hour Puzzle - Difficult Brain Teaser for Teens and Adults tangram wood puzzle How cool is thatA very interesting 3x3x3 cube brain teaser with only 1 solution. Designed by Stewart Coffin in 1975 who said that a half hour would be a good solution time. Good luck solving it under an hour! Deb says that's a GREAT solution time! (took her about 2 hours). This puzzle is very nicely made from our 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.
