How to Play Ball Sort
Tap any tube to select the top ball. The tube will glow and the ball lifts up.
Tap another tube to move the ball there. You can only stack same-color balls or fill an empty tube.
Each tube must contain only one color. Fill all tubes with a single color to complete the level!
Ball Movement Rules
Ball matches the top color of the destination tube, or the tube is empty.
Ball doesn't match the top of the destination tube, or the tube is full (4 balls).
Every tube contains exactly 4 balls of one color, or is empty. No mixed-color tubes.
Strategies to Solve Faster
Always keep at least one empty tube as a "buffer" — it's your escape hatch when tubes get blocked.
Work backwards from the solution: imagine each tube full of one color, then plan moves to get there.
Don't rush to fill a tube — sometimes leaving space open is the key to unlocking a tricky jam.
Use the Undo button freely on tricky levels. There's no penalty — it's a thinking game, not a speed game.
Look for "free moves": a ball that matches the top of another tube can be moved instantly for progress.
The Science of Satisfaction
Ball Sort taps into the deep human psychology of "completion". Our brains are wired to feel pleasure when we bring order to chaos. Each time you sort a tube perfectly, dopamine fires — and this game delivers that feeling repeatedly. No time pressure, no stress, just pure relaxing satisfaction and the quiet joy of puzzle-solving.
