Above:Brainball, out of package.
Click a thumbnail to see its larger version and description.
Spin the number ring, and twist the ends to flip seven of the thirteen numbers over.
The puzzle consists of a ring of thirteen numbered wedges looping around a sphere, much like the MagNif Saturn Puzzler. But instead of a twist of the sphere flipping half the numbered wedges, the twist flips four on one edge and three on the other edge.
There are at least three minor variants: ball can come with either black centre and blue end caps, or vice versa. The blue centred version can also be missing the embossed surface, being smooth instead of having the embossed "eye".
