Half Hour Puzzle - Difficult Brain Teaser for Teens and Adults tangram wood puzzle we could also customize theA 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).
