Star Sort

Puzzle · Hundreds of levels · Phone and desktop

Glass tubes hold stacks of sleepy stars and planets in mixed colours. Tap a tube to lift the top ball, then tap another to drop it on a matching colour or into an empty tube. A level is done when every tube holds a single colour. Levels add colours and tubes as you go, and from level 10 some balls stay hidden until they reach the top. Every colour also has its own face and pattern, so it plays well for colour-blind players.

How to play

  • Tap a tube to lift its top ball.
  • Tap another tube to drop it on a match or into an empty tube.
  • Fill every tube with one colour.
  • Fewer moves earns more stars.
