One color per tube
Ball Sort Puzzle gives you a row of tubes with coloured balls mixed through them. The goal is simple to say: group the colours so each tube holds a single colour. Do that and the level is done.
How you move
Drag the top ball of a tube — with the mouse, or one finger on a phone — and drop it into another tube. Only the ball on top can move, so every tube is a stack: to reach a ball near the bottom, you first have to put the ones above it somewhere.
Restarting costs nothing, so a level you have tangled up is one click from a clean start.
Why it gets harder
Early levels forgive anything. As you progress, the game adds more tubes and more balls, and that is where moving whatever is on top stops working.
Two habits that help
Two habits help. First, treat empty space as precious: an empty or nearly empty tube is the only room you have to park balls while you dig, so do not fill it with something you will need to move again. Second, finish a colour when you can: a tube that is already all one colour is out of the way for the rest of the level, which leaves fewer stacks to think about.
When you are stuck
The problem is usually a few moves back, not the move you are on. Restart and look at which tube you filled too early.
