How to Solve Color Sort Puzzles: Strategy Tips

Color sort puzzles look simple: pour colored liquid between tubes until every tube holds one color. Then you hit a level with twelve colors, two empty tubes and nowhere to go. This guide explains how experienced players think, so you can clear hard levels with fewer pours and fewer restarts.

1.Know exactly what a pour does

Every water sort, liquid sort and color sort game shares one rule: you can pour the top color of a tube onto the same color, or into an empty tube, as long as there is room. When you pour, all the matching layers on top move together, as many as fit. If only some fit, the rest stay behind.

That last detail matters more than it seems. A pour that only partly fits leaves a color split across two tubes, and splits are what make levels feel stuck. Keep it in mind for tip 7.

2.Look before you pour

The fastest way to lose a level is to start pouring right away. Take five seconds to scan the board first:

• Which colors are sitting on top, ready to move?
• Which colors are buried at the bottom of several tubes? Those will be finished last.
• Are any tubes already nearly done, with only one or two wrong layers on top?

A nearly finished tube is your best early target. Clear the one or two layers covering it, then top it up. Each completed tube is a tube you no longer have to think about.

3.Keep an empty tube free

Empty tubes are the most valuable thing on the board. They are the only place where any color can go, so they are your working space for untangling the rest.

A good habit: only pour into an empty tube when it starts something useful, such as a color you can keep stacking, or uncovering a layer you need right now. As soon as you can, empty a tube again by finishing or combining colors. Many hard levels are solved simply by always keeping one tube free until the very end.

Rule of thumb: if a move fills your last empty tube and you cannot see how to empty one again within two or three pours, look for a different move.

4.Build on clean bases

A tube that holds only one color, even a single layer at the bottom, is a clean base. Everything of that color can be stacked there without making a mess. Clean bases are almost as good as empty tubes, and you should look for chances to create them.

The best pours do two jobs at once: they add to a clean base and uncover something you can use next. Look for chains like that, where one pour opens up the following one.

5.Follow the color you have most of on top

When you are not sure what to do, count how many layers of each color are visible on top of the tubes. The color that shows up most often is usually the one to collect next: you can gather several layers in a few pours, and every pour uncovers new layers underneath.

Colors that are mostly buried are the opposite. Do not start a base for a color when three of its four layers are still at the bottom of other tubes; that tube will sit half-filled for a long time and block your working space.

6.Count the layers

Each color appears exactly as many times as a tube can hold, usually four. That simple fact helps more than you would think:

• If you can see three red layers on top or in a clean base, you know exactly where the fourth one must be.
• Before you pour onto a tube, check that there is room for all the matching layers you are moving.
• When a tube has, say, two free slots, think about which color will fill them, not just which color can go there now.

Counting turns guessing into planning. It also helps on levels with hidden layers, where the missing count tells you what a hidden layer can be.

7.Never split a color for nothing

Pouring three yellow layers into a tube with room for only two leaves one yellow behind. Now the color lives in two places, and you will need extra moves to bring it back together. Sometimes a split is necessary to uncover something, but it should be a choice, not an accident.

Before a big pour, look for the tube where the whole run fits. If none exists yet, make room first.

8.Plan your reveals

Some levels hide layers behind a question mark until you uncover them. In Potion Lab these are the mystery layers. They change how you should play:

• Reveal early. A hidden layer is a surprise that can ruin a plan. Uncover mystery layers while you still have an empty tube to react.
• Do not lock in a base too soon. If a color might be hiding in a mystery layer, keep some flexibility before you fill tubes completely.
• Use counting. If three of the four greens are visible, any hidden green must be the last one. Often you can work out a hidden layer before you see it.

9.Use undo to explore

Undo is not cheating; it is how good players test ideas. When you are unsure between two moves, try one, play a few pours ahead, and undo back if it leads nowhere. You will quickly learn which kinds of moves tend to trap you.

Watch out for loops: pouring a color from tube A to B and back again does nothing. If you notice that you keep returning to the same position, stop and look for a move that changes something new, like uncovering a buried layer.

10.Know when to add a tube

Many games let you add an extra empty tube when you are truly stuck. Use it when every move you can make is a loop, or when the only moves left would bury colors even deeper. Adding a tube early in a level wastes it; adding it when the board is nearly locked often turns a lost level into a quick win.

Common mistakes to avoid

• Filling every empty tube in the first few moves.
• Starting a new base for a color that is mostly buried.
• Pouring a run into a tube where it only partly fits.
• Finishing one color while burying the next one you need.
• Ignoring mystery layers until the board is already full.
