Ball Sort Puzzle

How to play ball sort

Tap a tube to lift its top ball, then tap another tube to pour it over — allowed when the target is empty or its top ball matches. You win when every non-empty tube holds four balls of a single color. Three difficulties scale the color count, and every level is generated by shuffling backward from a solved state, so a solution always exists.

Stuck? Undo steps back through your moves, restart redeals the same level fresh, and the extra-tube button buys breathing room once per level. Each color also carries its own symbol, so the game stays playable in grayscale or for color-blind players. Strategy: empty one tube early as workspace, never bury a color's last free ball under a stranger, and finish one color completely before starting the next.
