Hi Non-Twisty Puzzles fans, Cave Man was designed 8 June 1987, and first built in wood by Jean Carle and later by Tom Lensch. The puzzle is no longer available in wood, but now as 3D-print. The object is to remove the man from his cave. The puzzle is effectively a maze in a 3x3x3 cube, possibly the most complex maze in such a little space. Watch the YouTube video. Buy the puzzle at my Shapeways Shop. Read more at the Non-Twisty Puzzles. Check out the photos below. Enjoy! Oskar
