You've got tubes filled with mixed-up coloured segments, and a few empty ones to work with. Pour from one tube to another — but only onto a matching colour, or into an empty tube — until every tube holds a single pure colour. That one pouring rule is the whole game, and every puzzle is guaranteed solvable, so getting stuck always means there was a better order, not a dead end.
The difficulty grows the number of colours and tubes. A fresh daily puzzle lands each midnight, and the challenge link shares the exact arrangement.
Empty tubes are the whole economy of the game — spend them too early and a solvable board turns into a wall. Seven difficulty steps from Beginner to Cyborg add colours and subtract slack. The daily sort is the same for every player, and it is a different discipline from Connections: there the groups are hidden and you deduce them, here the groups are visible and the puzzle is the pouring order.
Of everything in Color Sort, the decision I'm proudest of is one you'll never see: every board this game deals is checked for solvability within its own tubes, and any generated board that can't be solved gets rejected before it ever reaches you. Plenty of sorting games skip that step and let you discover, fifteen pours in, that the deal was doomed from the very start. Not here. If a Color Sort board is on your screen, a path to the win exists. Whether you find it is between you and your pours.
That guarantee matters because of what this game's economy actually is: empty tubes. The empty-tube count per difficulty is the core dial of the whole design. Give players plenty of spare tubes and the puzzle breathes — there's always somewhere to park a colour while you dig for another. Take the spares away and every single pour becomes a commitment. Tuning that dial across the difficulty levels was the real balancing work of this build, because empty space is this game's only currency, and how much of it you're issued at the deal decides everything about how the next five minutes are going to feel.
Which is exactly why the classic mistake hurts so much: pouring early just to tidy. A tube looks messy, so you skim its top colour off onto another stack — it feels like cleaning, like progress. But if that pour splits a colour across tubes you can't later recombine, you haven't tidied anything at all. You've spent your scarcest resource to manufacture a brand-new problem. The discipline that separates finished boards from locked ones is simple to state: only pour onto a matching top colour, or into an empty tube with a plan for what that tube is for. And never, ever break a completed run — a finished or near-finished colour stack is banked progress, and disturbing it to make room is almost always the losing move dressed up as a clever one.
My own obsession with this game is a specific number: I want to solve a board in single digits — under ten moves. Still an elusive dream. But chasing it changed how I play. You can't approach single digits by reacting tube-to-tube; you have to read the whole deal before the first pour, spot which colour can complete earliest, and refuse every move that doesn't serve a completion. Most boards, I fall short. The chase is the fun.
Start on the generous difficulties and feel how the empty tubes carry you. Then move up and watch the same game turn ruthless. The daily deal lands at midnight, identical for everyone — and if you ever beat a board in nine moves, I would genuinely like to hear about it.
The empty tube is everything. It's your only workspace, so the fastest way to lose a solvable puzzle is to fill your last empty tube with a colour you can't immediately build on. Before every pour, I ask one question: does this keep a tube free, or does it trap me? Guard your empty space the way you'd guard the last bit of counter room in a small kitchen.
And think in whole colours, not single pours. Don't move a segment just because you can — look for the pour that completes a colour or frees a tube entirely. The winning sequence is usually "consolidate one colour fully, which empties a tube, which gives you room to consolidate the next." Plan the chain backwards from the tube you want to empty next, and the pours arrange themselves.
Color Sort looks like a fidget toy and quietly trains real planning — because every puzzle is solvable, getting stuck is always proof you moved in the wrong order, and learning to see the right order is the skill. What I love about Color Sort is that it's a pure challenge you set against yourself. You look at the tangle, you sense you can untangle it, and when you finally do — cleanly, in the right order — it's pure euphoria. No luck carried you there. It was all skill and patience and work, and pulling that off makes you feel, for a second, like a genius. That feeling is the whole reason to play.
You're learning to sequence under a tight constraint and to think a few steps ahead instead of pouring on impulse — the same discipline behind packing a car or organising a messy project. The harder levels add colours so the order matters more. No download, no sign-up — play in your browser on any device. If you like sorting puzzles, try Math Slide next.
