Ball Sort Puzzle Free is a clean, focused take on the color-sorting genre. Pour colored balls between tubes until each tube holds only one color. The rules are simple: a ball can only be placed on top of the same color or into an empty tube. Levels start with three tubes and gradually add more colors and fewer empty slots. A hint button reveals the next optimal move, and an undo button lets you backtrack mistakes. The minimalist design uses soft gradients and gentle pop sounds, keeping the focus entirely on the sorting logic.
