Rainbow Ball — small sliding ball with coloured balls

Rainbow Ball is a simple 3D sliding puzzle: there is one free opening in the sphere, and coloured balls move from place to place. The goal is to return each ball to the hole of the same colour. Smaller versions often have 12 holes and 11 balls.

Who this ball is for
