Pour the colored liquids from one glass tube to another until each tube holds a single color. It's a relaxing brain-teaser with hand-crafted, always-solvable levels, undo, and a coin reward every time you clear one.
About Water Sort Puzzle
Easy to start, surprisingly tricky to master. That's the whole appeal of Water Sort Puzzle, a wonderfully calming color-sorting game. Each level hands you a rack of glass test tubes layered with mixed-up colored water, plus a couple of empty tubes to work with. You tap a tube to lift it, then tap another to pour. But the liquid will only flow onto an empty tube or onto a matching color, and same-colored layers always travel together. From those two little rules grows a genuine logic puzzle. Every pour counts, dead-ends are real, and that satisfying click of snapping the last layer home never gets old. Worried about getting trapped? Don't be. Every board is generated and verified solvable, so you'll never be stuck with an impossible mess, and when you tie yourself in knots, Undo rewinds one move at a time while Reset hands you a clean slate. As you climb, levels gradually toss in more colors and squeeze your spare tubes, ramping the challenge without breaking that soothing one-more-level flow. Clear a board and you bank coins, then roll straight into the next.
Inside Water Sort Puzzle: what we checked
The numbers below come from Water Sort Puzzle's own source code, and the screenshots are from our own test run of the game (20 October 2026).
- Every tube holds exactly 4 layers. You may pour onto a tube whose top colour matches, or into an empty tube, and a pour moves the whole run of that colour on top for as long as there is room.
- Level 1 has 3 colours and 2 empty tubes. Each level adds one colour up to a maximum of 9, and from 8 colours up there is only 1 empty tube.
- Each deal is checked by a solver before you see it, so it can be finished. Only if 200 shuffles in a row fail the check does the game fall back to an unchecked deal, and Reset and New are there for that case.
- A solved level pays coins: 40 plus 8 per level number, minus 2 for every move beyond twice the level number, with a floor of 15. Level 1 pays 48 coins if you finish in two moves.
- Undo has no limit within a level, Reset puts the tubes back as dealt, and Hint flashes one useful pour.
- Your level and coin total are saved in this browser, so closing the page does not send you back to level 1.

How to play Water Sort Puzzle
Tap a tube to select it and it lifts up to show it's ready to pour. Tap a second tube to pour the top color across. Here are the limits: you can only pour onto an empty tube or on top of the same color, all connected same-color layers move at once, and a tube can never overflow past four layers. Keep pouring and consolidating until every tube is either empty or filled with one single color to finish the level. Need to backtrack? Use Undo for one move, Reset to restart the board, or New to deal a fresh layout. Each cleared level pays out coins, and the puzzles add more colors as you climb.
Controls
Click or tap a tube to select it, then click or tap another tube to pour. Tap the selected tube again to deselect. Buttons: Undo, Reset and New. Fully playable one-handed on mobile.
Tips & tricks
- Always keep at least one empty tube free as breathing room — filling them all is how you get stuck.
- Only pour onto a matching color when it makes real progress; needless pours waste your space.
- Finish (complete) a tube whenever you can to free the colors stacked on top elsewhere.
- Stuck? Undo a few moves and try routing a color through a different tube — every board is solvable.
