How a water sort puzzle works

Each flask holds up to four layers of colored liquid, and at the start the colors are all mixed up. Tap a flask to pick it up, then tap another flask to pour. The rule is simple: you can only pour onto the same color, or into an empty flask, and only if there is room. When every flask is either empty or filled with one single color, the level is solved.

It sounds easy, and the first levels with three colors are. As more colors arrive (up to twelve), the board fills up and the order of your pours starts to matter a lot. That is what makes a good water sort puzzle so satisfying: you are always one clever pour away from untangling everything.

Tips to solve harder levels

• Protect your empty flask. An empty flask is your most valuable tool. Do not fill it with a color unless that pour finishes something or opens up several new moves.
• Look for colors that are almost done. If three layers of red are already together, find the last red and plan the path to free it.
• Think two or three pours ahead. Before you pour, ask which flask that move will open up, and whether the newly exposed color has somewhere to go.
• Pour whole blocks. When the same color sits in two layers on top, both pour together if there is room, which saves moves.
• Use undo freely. Undo is there to explore. Try a line, and if it leads nowhere, step back.
• Restart when the board is jammed. A fresh start often shows you a better first move.

Why water sort is so relaxing

Sorting puzzles give your brain a small, clear goal and a visible sense of progress: the board literally becomes tidier with every pour. There is no clock in Flaskle, so you can stop and think as long as you like, and the smooth pouring animation and soft sounds make each move feel good. Many people play a level or two as a short break from work or before bed.

What makes Flaskle different

• Every level is checked to be solvable, so you never waste time on an impossible board.
• Stars for efficiency. Beat the par move count for three stars, or just solve it your own way.
• Colorblind-friendly. Every color also carries its own symbol, so you never have to tell two similar shades apart.
• Daily Challenge. The same puzzle for everyone each day, with a streak counter.
• Works on phones, tablets and computers in any modern browser.

A worked example

Imagine three flasks: the first holds red over blue, the second holds blue over red, and the third is empty. Pour the top red from the first flask into the empty one. Now the first flask shows blue on top, so pour the top blue from the second flask onto it. The second flask now shows red, which can go onto the red in the third flask. Every pour either joins a color to its match or frees a flask, and that is the whole game in miniature. Bigger levels simply add more colors and more layers, so the same habit of looking for pours that join and free works all the way up. When you are unsure, count how many of each color are still hidden under other colors: the color with the fewest hidden layers is usually the best one to finish first.
