**Description:**

This puzzle is formed by two interconnected rings full of balls that can move all over each ring.

The rings have two intersections where they share one ball. By spinning the rings and changing the common ball the colours are mixed or arranged.

The Rubik's rings version has 34 balls of three colours. The intersections divide the puzzle into 4 sections; there are 5 balls on the inner sections, 1 on each intersection point, and 11 balls on each one of the outer section.

In its solved state the 11 blue, 11 red, 12 yellow balls are arranged so that the outer sections are red or blue, and the inner sections and intersections are yellow.
