About Water Sort Puzzle

Water Sort is a colour sorting puzzle, also called liquid sort or color sort: pour coloured water between cups until every cup holds a single colour. It starts simple and keeps adding twists (faucets, single-colour cups, cups that turn upside down, lids) across 399 levels. Free in your browser, nothing to install.

How to play Water Sort

  • Tap a cup, then tap another to pour into it.
  • You can pour onto an empty cup or onto the same colour.
  • A cup holds four layers, and matching layers on top move together.
  • Sort every colour into a cup of its own to finish the level.
  • Fewer moves earn more stars: three, two or one.

How many levels are there?

399, with new mechanics introduced along the way.

How many layers fit in a cup?

Four.

How are stars counted?

By the number of moves: finish in fewer moves for three stars. Undo does not count against you.

Is my progress saved?

Yes. Your level, stars, coins and unlocked styles are kept.
