Sort Balls - Puzzle

Sort Balls - the addictive puzzle game where you should use attention and logic to sort all color balls by the different tubes.
It is like chess but more interactive and a little bit simple thats good even for kids who dont know chess rules and strategies.

In every level you have a back button (but only 5 charges) so be careful and calculate actions by several steps ahead.
Also, if you get stuck it is possible to use a special + "additional tube" button.
