Play the puzzle in the browser
Open the game page and start at level 1. Every level is generated from a fixed seed and checked by a solver before it loads, so no level on this site is impossible. Undo, a hint that comes from a real solution path, an extra bottle and restart are all available.
Learn the rules properly
Most players learn Water Sort by trial and error and then stall around the six-colour puzzles. The rules page spells out what a legal pour is, including the cases people get wrong: partial pours, the four-unit ceiling and why a finished bottle should never be touched again.
Pick up the thinking, not just tricks
Our strategy guide and move planning guide explain the two ideas that decide almost every puzzle: how much free space you have, and how many separate fragments each colour is split into.
Get unstuck on a specific level
If a particular board is beating you, the level walkthroughs show the opening moves for the hardest levels here, and solving difficult levels explains how to recover a board that already looks lost.

What we test
before a level ships.
A Water Sort board is not interesting simply because it has more colours. A good board gives you choices, makes those choices meaningful, and still leaves a path back when you make a poor decision. That is the standard we use when building the browser game.
1. We check the rules, not just the final picture
Every move in the browser game follows the same four-unit bottle limit and top-colour pouring rule described in our guides. A level is useful only when the player can understand why a move is legal or illegal from the board itself.
2. We check that the starting board has a solution
The browser levels are checked with a solver before they are presented. This does not make every player move correct: a solvable starting board can still become deadlocked after a bad sequence. Our hint and level guides explain both the solution path and the recovery options.
3. We teach the decision behind a move
The most useful Water Sort lesson is not a list of moves to copy. It is learning to count free space, notice which colour is split across several bottles, and protect the empty bottle that gives you room to recover. Our strategy, techniques and level-guide pages are written around those decisions and can be tested immediately in the browser game.
4. We keep the site transparent

OUR PUZZLE NOTES
Why some boards
feel harder than others.
Difficulty in Water Sort is not simply the number of colours on the screen. Two boards can contain the same number of bottles and still feel completely different because their colours are arranged differently. A board becomes demanding when useful colours are buried, free space is scarce, and an apparently harmless pour removes the only route for recovering a later colour.
Free space is a resource, not decoration
An empty bottle can receive any colour, while a partly filled bottle can usually receive only one colour. That means one empty bottle can be worth several ordinary spaces. When planning a move, we therefore ask what free capacity will remain after the pour, not just whether the pour is legal right now.
Fragmented colours create the real planning problem
Imagine one colour appearing in three different bottles. Joining two visible pieces may look productive, but it can also cover a colour that you need next. The better question is: which move reduces fragmentation while keeping at least one useful destination available? This is why our strategy guides focus on colour fragments and future capacity rather than on memorising move sequences.
Good solving is reversible when possible
A strong early move either makes progress or creates a clear way back. A risky move fills the board with new constraints without exposing anything useful. If a pour does not expose a colour, reduce fragmentation, or create useful space, it deserves a second look before you commit to it.
These principles are also how we explain our browser levels: the goal is not to make a board artificially confusing, but to make the consequences of a player's choices visible. You can test the ideas immediately in the browser game and then compare your reasoning with the strategy guide.
IN SHORT
What Water Sort
Puzzle is.
You are given a row of bottles. Each bottle holds up to four units of coloured liquid, and the colours start mixed. You may pour from one bottle into another only when the receiving bottle is empty or already has the same colour on top, and only while it has room. The puzzle is solved when every bottle is either empty or filled with one colour.
There is no timer and no dexterity involved. The whole difficulty comes from ordering: liquid can only be taken off the top, so a colour buried under three others cannot be moved until you clear what sits above it. That single constraint is what turns a simple idea into a genuine planning puzzle — and it is why the same board can be trivial or unsolvable depending on which pour you make first.
