The Impossible Dovetail Puzzle has a unique mechanism set up that keeps the two wood pieces cleverly lock to each other with the dovetail joint. The dovetail joint looks impossible to solve, but hold on, there is a clever way to open this box. It will take only 2 moves to open this trick opening puzzle! How difficult can it be? Well, the solution itself is very simple (which I think adds to the puzzle more appeal), but very few will find the solution without having some knowledge about the puzzle history and style. The parts will move easily and smoothly if you do it the right way. When the mechanism is solved, the two-piece will open.
