This hand-crafted wooden box with eight square pegs will drive you crazy!
The object is to arrange the pegs (numbers 1-8) such that no consecutive number touches on any connecting line. For example number 1 cannot connect with number 2; number 2 cannot connect with 3 or 1; number 5 cannot connect with 4 or 6; etc. It's an intriguing puzzle that draws people in. It looks easy but once you start rearranging the pegs the complexity of the task reveals itself.
Measures 4.5" by 3" by 1.5"
I love all things Martin Gardner as he was a mentor and friend. The idea for this conundrum came from his book: The Colossal Book of Short Puzzles and Problems, 2006. Gardner wrote, "This perplexing digit problem, inventor unknown, was passed on to me by L. Vosburg Lyons of New York City (February 1962). There is only one solution but if you try to find it without a logical procedure the task will be difficult. A digital computer running through all possible permutations of the digits finds 40,320 different arrangements possible." I've found there are actually four solutions but each one of those is a mirror of the one true solution.
This wooden puzzle is made of hardwood and built to last a lifetime. The pegs were made square to keep the numbers oriented properly. The numbers are laser engraved, not inked, so they will last. Comes with a base and cover. The cover has the title and instructions laser engraved into the surface. This is something you'll proudly display on your desk. You will also enjoy watching others being perplexed by it.
Made in the USA.
