Fit the chain into the box.
This popular puzzle originally won a Jury Honorable Mention for Goh Pit Khiam in the Kyoto IPP design competition. This version has been 3d printed by Rex Rossano Perez. The goal is to store all the chain links in the box so that nothing sticks out. A perfect puzzle for the coffee table since all the pieces are locked together and won’t get lost. Also, the solution is really fun – not so hard that a little persistence and logical thought won’t puzzle it out. Find out why this one is so popular!
