Rainbow ball logic game

This logic puzzle is a ball with coloured holes on its surface, and most of the holes have a smaller ball inside the ball. The aim is to move the inner balls around until each one returns to the hole of its matching colour. One hole is left without a ball, which leaves room for the pieces to shift.

Unlike a Rubik's cube, you cannot fully see or reach the parts, so you have to work from the coloured holes on the outside. This makes the challenge more focused and more demanding than it first appears.

Designed for one player aged 6 and up, the puzzle builds spatial thinking, patience and step-by-step reasoning.
