Key Puzzle, key, puzzle
Haunted Key and Nut Puzzle. This looks simple but to the uninitiated could give them pause for thought. The object is to remove the key from within the brass nut.
Precision made puzzle by the folks at Viking.
As suggested and designed by Rob Hartmann who entered his idea in the World Puzzle Contest (Puzzle Design Competition at the International Puzzle Party-Helsinki). Awards and judging are still to come and we wish Rob good luck.
