The Ball Sort Puzzle has been my guilty pleasure for a long time. I had a version installed on my tablet and every night before going to bed I would play a few levels. At this moment, the counter is above level 3100.

The game meets all the requirements of a casual puzzle game. You have to think a lot, it’s not always very simple, you have to think a few steps ahead, but if you’ve done all that, the puzzle doesn’t take very long. Very suitable for killing time or to clear your mind for a while.

There are a lot of versions around in the Play Store, they all contain a lot of bloat, just to keep you busy and be able to display as many advertisements as they can. That’s why I decided to make my own version, simple and straightforward. Alternating an easier level with 11 tubes and then a harder one with 14 tubes.

The rules of the game are very simple. You have a number of columns filled with four colored balls, and 2 empty columns. You may move a ball to a column where the top ball has the same color and was not yet full. Or to an empty column. The goal is to fill all columns with balls of the same color while keeping 2 empty columns.

I got tired of all the advertisements and the limited number of undo’s. Therefore I created my own version. This version has unlimited undo’s and there is a check if the current situation is solvable. To prevent cheating, the check is only performed every 30 seconds.

Here you can try it online.
