Game: Rings Sorting

In this game there will be some poles with different coloured rings stacked on them. The aim of this game is to arrange the rings so that same coloured rings are on the same poles. Naturally, you can only move the ring that is on the top of a stack to another stack. When a pole is full, you can no longer put rings on it. After you finish, a new level will be presented with more poles and more rings and more colours. Formulate a plan to move the rings and this game can be won easily. The faster you finish, the higher your rank.
