Half Hour Puzzle - Difficult Brain Teaser for Teens and Adults

A 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.
