The puzzle is to fit the six double-layered pentominoe pieces into the tray. It's pentominoes as you know them, with a twist, or two....
What unusual pieces they are.?? Each piece could actually be called two pieces. 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.
This double-layered joined pentominoes puzzle is a great new concept designed by Jurgen Reiche.??
