🧪 Ball Sort
A calm puzzle: sort colorful balls into tubes so each tube holds one color. Dozens of solvable levels, undo and an extra tube. Free, no sign-up, full screen.
How to play
- Tap a tube to lift the top ball.
- Tap another tube to put the ball down there.
- A ball can only go on a ball of the same color, or into an empty tube. Each tube holds 4 balls.
- When every full tube has just one color, the level is done.
- Made a mistake? ↩ undoes a move. Really stuck? ➕ adds one empty tube per level.
Tips from the champions
- Keep an empty tube for as long as you can. It is your strongest tool.
- Finish a color that is almost complete first.
- Every ball also has a small symbol, so you can play without telling colors apart.
