I haven't successfully completed a puzzle in many years, but that may all change thanks to the Wooden Beer Mug Puzzle. This 3D puzzle may look simple, but like walking down the hall after a long night of drinking, it is deceptively difficult.
A good puzzle needs to be both challenging and fun to look at once completed. The Wooden Beer Mug Puzzle meets and exceeds both of those standards with ease. If you enjoy a good brain-teaser and beer, then you definitely want to check this puzzle out.
