"[1] Bobby's brothers have been led astray by their rogue cousin and are now lost in the Metaplanes outside their home - stunned and captured by the evil Bearings that inhabit the Planes.

He must avoid the evil Bearings, find his missing and unconscious relatives, and roll them out of the Metaplanes to safety.

The mission must be accomplished before the time limit runs out, otherwise the game ends and Bobby's relatives are lost forever.

The funny thing is, though, that there was no sense in which Bobby was based on Marble Madness, or any home micro game such as Gyroscope, and especially not Spindizzy!
