If I understand the question right, you need to transfer all spheres to the right "pole". It's one with blue and red spheres in your screenshot.
The catch is - you can only transfer sphere to a "pole" if there's no sphere present with a higher standing. In other words, you can't move a red sphere to a pole if there's any orb already there. And you can't move the green orb to a pole with the blue one.
