The object of the puzzle is to open the cylinder.
As usual with Wil's designs, this is nowhere near as easy as it sounds! And sound is important when solving this puzzle. This puzzle does not give up it's secrets easily and like a lot of Wil's puzzles you are often working blind.
Size: Diameter of the cylinder is 40mm. Height 50mm.
A very well crafted puzzle milled from solid polished aluminum. The lid of the puzzle is engraved with a number and the base with Wil's signature.
Wil is a true puzzle solver and has the philisophical view that puzzles should not come with solution sheets. So, if you purchase one of these puzzles there will be no solution supplied. If you're not convinced that this is a 'must have' puzzle here's one review I found but a simple search on Google will find many others.
