VTG Fifteen Puzzle by ThinkFun Inc. Retro Small Travel Puzzle Enamel Stainless S

Missing booklet

The Fifteen Puzzle is, to this day, one of the most recognizable puzzles of all time. With its origins dating back to 1880, the original designer is still a topic of debate, although many say it was invented by Sam Loyd, one of the greatest American puzzle inventors.

The version you see in the photo, by ThinkFun, is actually a remake of an old puzzle called "The IMP" from 1933. Made from stainless steel and decorated with enamel (melted powdered glass), the puzzle keeps the original design intact and true to its origins. The result is a retro-looking puzzle, and due to its small size (6cm - 2.3") it's perfect to take with you on long travels. It comes with a travel case as well. If you know how to solve a classic sliding puzzle - whether it's a 9 or a 15 puzzle or any other combination - you won't have much trouble to solve any of the 30+ challenges available to you. The Fifteen Puzzle is the real deal when it comes to sliding puzzles and a classic in its own merit.
