Ball Sort

How to play Ball Sort

Tap a tube to pick up its top ball, then tap another tube to drop it there. A ball can only go onto an empty tube or onto a ball of the same colour, and each tube holds four balls. If several balls of the same colour sit on top of each other, they all move together when there is room. Fill each tube with a single colour to win the level.

Levels start with three colours and add another colour every few levels, up to nine. There are always two empty tubes to work with.

Controls

Tap or click the tube to move from, then the tube to move to. Tap the same tube again to cancel. Undo takes back your last move.

Tips

• Keep an empty tube free. An empty tube is your most valuable resource. Fill it only when it helps finish a colour.
• Finish one colour at a time. A completed tube is out of the way for good.
• Dig for buried colours. If a colour you need is near the bottom, plan where the balls above it will go first.

About this game

Colour sorting puzzles are one of the most popular relaxing game styles on phones. Homivoo's version generates each level from a seed and runs a search to confirm it can be solved before it is shown.
