About

What is Water Sort?

Water Sort is a logic puzzle played with tall glass tubes of colored water. Every color appears four times, which is exactly enough to fill one tube. At the start those colors are mixed. You win when every tube holds a single color, or is empty.

The small rule set is why the puzzle is easy to learn and still easy to jam. You can pour only the color at the mouth of a tube. It can land in an empty tube, or on the same color, and only while the destination has space left. A stack of the same color moves together, so one pour can shift a single layer or several at once.

Play Water Sort online in your browser

watersort.io opens straight into the puzzle. There is no install step, so you can scan the tubes and start sorting on a laptop or a phone. The board uses the same click-or-tap control on both: choose a source tube, then choose where the water should go.

Later levels add more colors, but the goal does not change. Read the color at the top of each tube, keep enough empty space to move, and pour only when the next board will be easier to read than this one.

Guide

How to play Water Sort

Finish the level with one color in each filled tube. Move only the water at the top of a tube, and keep untangling the stacks until the board is sorted.

  1. Pour onto the same color, or into an empty tube

    Tap the tube you want to pour from, then tap the destination. The move is allowed when the destination is empty or already shows that color, and when it still has room. A full tube, or a different color on top, will not accept the pour.

  2. A matching run moves together

    If two or more layers of the same color sit together at the top, they pour as one group, up to the space in the destination. A tube with only one free slot takes a single layer and leaves the rest behind.

  3. A finished tube stays sealed

    Four layers of one color close that tube. You cannot pour out of it again. The level is clear when every tube is sealed or empty.

  4. Use undo, a hint, or one extra tube

    Undo steps back one pour. Restart returns the level to its first layout. Hint points at a legal next move when one can be found quickly. Extra tube adds a single empty bottle for that level if you want more room.

Strategy

Water Sort tips for harder levels

A legal pour is not always a useful pour. The board gets stuck when the last empty tube is filled before a buried color has somewhere to go.

  • Look at the color under the one you are about to move. That hidden layer is often the real reason to pour.
  • Keep one empty tube until you can see the next two moves. It is temporary storage, not a tube you have to fill.
  • Join a color when the pour reveals a useful layer or finishes a tube without trapping the rest of the board.
  • If two pours both look legal, prefer the one that leaves an empty tube or reduces the number of split colors.
  • When a layout feels jammed, undo a few pours instead of adding the extra tube on the first try.

FAQ

Water Sort questions

Is Water Sort free to play?

Yes. The puzzle on watersort.io runs in the browser. There is nothing to install and no account to create.

How do you pour in Water Sort?

Tap a tube, then tap the tube that should receive the water. The top color moves only into an empty tube or onto the same color, and only when the destination has room.

Why can't I pour this color?

The destination is full, its top color is different, or the source tube is already sealed. A sealed tube is full of one color and stays closed.

Does Water Sort have a time limit?

No. Take as long as you need. Undo and restart are there so you can try another order without starting the whole game over.

What does the extra tube do?

Each level can add one empty tube. It makes a tight board easier. The level can still be solved without it.

Are the levels solvable?

Yes. Each level starts from a finished board and is scrambled with moves that can be reversed, so a way back to the sorted tubes always exists.

Ready to play Water Sort?

Open a level, read the colors at the top of the tubes, and sort the board one pour at a time.
