How to Play Water Sort Puzzle – Sort Color

Water Sort Puzzle – Sort Color is a relaxing yet challenging colour-sorting game where you pour coloured water between glass tubes to arrange each colour into its own tube. This guide will teach you the basics and give you a clear method to solve puzzles.

  • The game is published by Guru Puzzle Game on Google Play.
  • There is no time limit, so you can think at your own pace.
  • The goal is to sort all colours so each tube contains only one colour.

The Basics: Rules and Goal

The Goal

Your objective is to sort all the coloured water so that each tube contains only one colour. You start with several tubes, some filled with mixed colours and some empty.

  • A tube is considered complete when it is filled with a single colour.
  • You win when all tubes are sorted and no mixed tubes remain.
  • Empty tubes are essential for temporary storage.

How to Pour

To pour water, tap a tube to select it, then tap another tube to pour the top colour into it. You can only pour if the receiving tube has enough space and the top colours match or the receiving tube is empty.

  1. You can only pour the top layer of liquid from a tube.
  2. You cannot pour onto a different colour unless the tube is empty.
  3. If the receiving tube is empty, you can pour any colour into it.

No Time Pressure

There is no timer, so you can take as long as you need to plan your moves. This makes the game relaxing and suitable for thoughtful play.

  • You can undo moves if you make a mistake.
  • You can restart a level at any time.
  • The game encourages experimentation without penalty.

Visual Walkthrough: A Simple Sort

Step 1: Analyse the Tubes

Look at the tubes and identify which colours are on top. In our example, we have three tubes: one with red on top of blue, one with blue on top of red, and one empty tube.

  • Top colours are the only ones you can move.
  • The empty tube is your temporary storage.
  • Your goal is to separate red and blue.

Step 2: Pour Red into the Empty Tube

Tap the tube with red on top, then tap the empty tube. The red liquid pours into the empty tube, creating space in the first tube.

  • Now the first tube has only blue left.
  • The empty tube now contains red.
  • You have made progress towards sorting.

Step 3: Pour Blue onto Blue

Tap the tube with blue on top (the second tube), then tap the first tube (which now has blue at the bottom). The blue pours onto the matching blue, completing the blue tube.

  • The second tube is now empty.
  • The first tube is full of blue.
  • You have one colour sorted.

Step 4: Pour Red into the Empty Tube

Tap the tube with red (the former empty tube), then tap the now-empty second tube. The red pours into the empty tube, completing the red tube.

  • All tubes are now sorted.
  • The puzzle is solved.
  • This simple example illustrates the core loop.

Key Concepts for Success

Temporary Storage

Empty tubes are your most valuable resource. They allow you to temporarily hold a colour while you rearrange other tubes. Use them wisely and try to free them up as soon as possible.

  • Never fill an empty tube completely unless it is the final colour.
  • Plan to empty a tube back out quickly.
  • Having multiple empty tubes gives you more flexibility.

Free Containers

A free container is any tube with space at the top. You can use it to pour a colour even if it doesn't match, as long as the tube is empty. This can help you access colours buried under others.

  • An empty tube is a free container.
  • A partially filled tube with matching top colour is also useful.
  • Try to keep at least one free container available.

Move Order

The order in which you pour matters. Sometimes pouring one colour before another can block your progress. Think about the consequences of each move before you make it.

  • Consider what will be exposed after a pour.
  • Avoid pouring a colour onto a tube that will then be stuck.
  • Look for moves that create more options.

Colour Accessibility

A colour is accessible if it is on top of a tube. If a colour is buried, you need to move the colours above it first. Focus on making buried colours accessible.

  • Only top colours can be poured.
  • Plan to uncover colours you need.
  • Sometimes you must make temporary moves to access a colour.

Avoiding Blocked Layers

A blocked layer occurs when a colour is trapped under a different colour that cannot be easily moved. Avoid creating situations where you have no legal moves.

  • Always check if a pour will leave you stuck.
  • If you are stuck, undo or restart.
  • Try to keep at least one empty tube to escape blocks.

Step-by-Step Method

Planning Several Moves Ahead

Think Before You Pour

Before making a move, consider what the board will look like afterwards. Will you have an empty tube? Will you expose a needed colour? Will you create a blocked layer?

  • Visualise the result of the pour.
  • Check if the move creates new options or limits them.
  • If unsure, try a different move first.

Look for Chains

Sometimes a series of moves can be linked together to achieve a bigger goal. For example, pour A to empty, then B onto A, then C onto B, freeing up a tube.

  • Identify sequences that free up multiple tubes.
  • Chains can quickly sort several colours.
  • Practice recognising chain opportunities.

Avoid Dead Ends

A dead end occurs when no legal moves remain. To avoid this, always keep at least one empty tube or a tube with space. If you find yourself in a dead end, undo or restart.

  • Dead ends often result from careless pours.
  • Keeping an empty tube prevents most dead ends.
  • Don't be afraid to restart if needed.

Common Mistakes to Avoid

Mistake

Pouring Without a Plan

Randomly pouring colours often leads to blocked layers and dead ends. Always have a goal in mind for each move.

  • Take a moment to analyse before acting.
  • Ask yourself: does this move help sort a colour?
  • If not, look for a better move.
Mistake

Filling Empty Tubes Too Quickly

Empty tubes are precious. Filling them with a colour that you can't move later can trap you. Use empty tubes only for temporary storage.

  • Try to keep at least one empty tube.
  • If you fill an empty tube, plan to empty it soon.
  • Avoid pouring a colour into an empty tube if it blocks other moves.
Mistake

Ignoring Buried Colours

If you focus only on top colours, you may forget about colours buried underneath. Keep an eye on what needs to be uncovered.

  • Regularly scan all tubes for buried colours.
  • Plan moves that expose needed colours.
  • Sometimes you must make temporary moves to access a colour.
Mistake

Not Using Undo

The undo feature is there to help you. If you make a mistake, don't hesitate to undo and try a different approach.

  • Undo can reverse a bad move instantly.
  • It's better to undo than to struggle with a blocked board.
  • Use undo as a learning tool to see what works.

Practice Makes Progress

Like any puzzle game, Water Sort Puzzle rewards practice. The more you play, the better you'll recognise patterns and plan ahead. Don't be discouraged by difficult levels—take a break and come back with fresh eyes.

  • Try to solve puzzles without using undo to challenge yourself.
  • Experiment with different strategies.
  • Share tips with friends who play.
