Nails puzzle
Mechanical puzzles have been around for centuries. What makes a great mechanical puzzle is that it looks simple but is difficult to solve. A good example is the classic puzzle consisting of two twisted linked
nails which one must unlink. On first glance one expects to solve it in seconds. But many people find it much more difficult than it appears. Such puzzles are simple and complex at the same time, as is the case with Quzzle.
