Hoop Stack

Game description:

This puzzle may seem simple at first, but once you start playing it, you'll realize there is a daring task ahead of you! You'll see several piles of hoops on the screen. All of them are of different colors. Your goal is to sort them out into stacks according to that parameter. The catch is that you can only move the upper hoop. Until you remove it from the top of the stack, you won't be able to do anything with those lying lower. That will require a lot of logic, but if you give it a little thought, you will surely cope with all the challenges!
