Are you up for the challenge of Quantamino?
The classic pentamino shape game has gone 3D! No more flat thinking, Quantamino™ takes the mind-bending fun of pentas and adds a vexing 3rd dimension. This excellent educational tool demonstrates how shapes can be arranged into predefined spaces. The rules are simple, the solutions almost endless: Simply empty the frame. Remove any one penta and put it inside the small sectioned off space of the box. Then try to fit the remaining 16 pentas within the larger empty frame so that no pieces protrude and there are no empty areas within.
