The puzzle is to fit the six pieces into the tray. It's pentominoes as you know them, with a twist, or two....
But what unusual pieces they are. Each piece could actually be called two pieces. But they are joined by a hinged screw so the shape is flexible. And the tray has drilled circles in the base into which the screw heads fit... or sometimes don't fit.
A great new concept designed by Jürgen Reiche.
