The Ball of Whacks is back - bigger, better and more colorful than ever!

Why not add more pieces and more shapes to create a bigger and better design? Roger Von Oech thought the same thing, and put his notion to good use.

Introducing the BIG Ball of Whacks - the colorful version!

Two new pyramid-shaped pieces introduce a new way to stimulate your thinking. Dividing the 30-sided rhombic triacontahedron into 36 magnetic pyramids gives you three different shapes: Whacks, Flat-Whacks, and Half-Whacks.

Containing 197 rare earth magnets, 36 specially shaped pieces "click" together magnetically to form an endless variety of geometric shapes, quirky structures or a perfect rhombic triacontahedron.

Addictive fun you hold in your hand!

Patented Whack design is governed by the golden ration. By adding two additional pyramid-shaped pieces, this complex structure presents a greater challenge in reconstructing the Ball shape.

Hands and eyes work together and neurons start firing.

Stimulating brain activity, inspiring creativity, refreshing your mind and challenging your intellect, The Big Ball of Whacks is designed for artists, engineers, writers, designers and YOU!

Not for children under 14 years of age.
