Water Sort Puzzle Strategy
Read the pour before you make it: how many layers will move, where they can land, and what color they will reveal. That is more useful than choosing whichever bottle looks easiest to tidy.
Count the whole pour, not just the top layer
In our water sort game, a pour moves the uninterrupted run of one color at the top, up to the space available in the destination. You can pour into an empty bottle or onto the same color. A full bottle cannot receive more liquid.
For example, two yellow layers on top move together into an empty bottle. If the receiving bottle has only one free space, just one yellow layer moves; the source still shows yellow. Check that remaining layer before assuming the pour has uncovered a new color.
That is the main difference from our ball sort strategy: balls move one at a time. A solution written for one-ball moves may stop matching a liquid game as soon as a two-layer run reaches the top. Check the rules of the app you are playing.
Give each empty bottle a job
An empty bottle can receive any exposed color. Once you put green in it, only green can join that top layer until you move the green away. Before occupying the bottle, choose the move it will make possible next: uncovering red, gathering a green run, or emptying another mixed bottle.
Keeping an empty bottle available is a useful habit, not a rule you must obey on every move. Some solutions use both spare bottles temporarily. The question is whether you have a legal route to recover space. Write down the next two pours before taking your last empty bottle.
Also distinguish a nearly finished color from a blocked color. Three red layers gathered in one bottle need the fourth red to finish. If that last layer sits under yellow and green, find somewhere for those colors first. Filling the remaining spare bottle with an unrelated color can make the red bottle look promising while leaving you with no way to reach the last red.
An eight-pour worked example
Each bottle holds four layers. Read the picture from the bottom up; the numbers printed inside the layers identify colors, while the numbers below identify bottles.
Load this exact example in the water sort solver. Press Solve, then use the next-step button to compare each pour with the list below.
- Bottle 1 → Bottle 4: 2 yellow layers. Both yellow layers leave bottle 1, revealing red.
- Bottle 2 → Bottle 1: 1 red layer. The exposed red joins the two reds in bottle 1.
- Bottle 2 → Bottle 5: 2 green layers. The green run moves together into the other empty bottle.
- Bottle 2 → Bottle 4: 1 yellow layer. Yellow leaves bottle 2, which is now empty.
- Bottle 3 → Bottle 5: 1 green layer. Green joins the green run in bottle 5, revealing red.
- Bottle 3 → Bottle 1: 1 red layer. Red completes bottle 1.
- Bottle 3 → Bottle 4: 1 yellow layer. Yellow completes bottle 4.
- Bottle 3 → Bottle 5: 1 green layer. The last green completes bottle 5.
You finish with red in bottle 1, yellow in bottle 4 and green in bottle 5; bottles 2 and 3 are empty. This is a legal solution, without a claim that it uses the fewest pours. Notice what the opening accomplished: pouring yellow out made a landing place for the red on bottle 2, which then exposed the green run.
Recover from a stuck position
Pause when a pour only moves a uniform color back and forth without uncovering anything or opening space. The bottle numbers change, but your options do not improve. Look at the last move that occupied an empty bottle or buried a color you still need.
- Use Undo to return to that decision. In our game, Undo is free and unlimited.
- Check the exposed runs and available spaces again. A matching color is not a legal destination when the bottle is already full.
- Try a different destination, then check what the next pour reveals.
- If you want help, copy the current position into the water sort solver. Match the capacity and every empty bottle, and enter each layer bottom to top.
A solver result is useful only if the copied board matches your game. A search that stops without finding a solution does not establish that the puzzle is impossible. Check the input and the game's rules before restarting or buying an extra bottle in another app.
Keep unknown colors unknown
With question-mark layers, you cannot plan a complete sequence from a fully known board. Record each newly revealed color and reassess after the reveal. Treat any plan that depends on a hidden layer being red as conditional: it may need to change when that layer becomes visible.
Our solver accepts visible colors only. If your app permits Undo, you can inspect a branch and return, but first check whether revealed colors remain visible after undoing. When every layer is known, enter the current arrangement, not a mixture of earlier and later screenshots.
Common water sort questions
Is there a trick to water sort puzzle?
Before pouring, check the top run, the room in the receiving bottle and the color you will uncover. Use empty bottles to create a useful next pour. These checks help you plan, but they are not a guarantee that every choice leads to a solution.
How many levels are in the game Water Sort Puzzle?
That depends on the app and version. Our browser game generates levels as you advance, rather than using a fixed published list. Its level numbers do not identify levels in other Water Sort apps.
Is there a water sort puzzle solver that can solve puzzles with unknown colors?
Some tools offer a mystery mode, but our solver currently needs every layer to be visible. Keep a record of revealed colors, use Undo when your game allows it, and enter the current arrangement once all colors are known. Do not replace an unknown layer with a guessed color and treat the result as certain.
