Neon Sort Lab

Pour glowing neon liquids between lab tubes until every tube is full of a single colour.

Tap a tube to lift it, tap another to pour. Liquid only moves onto its own colour or into an empty tube, and only if there is room. That is the whole rule.

EVERY BOARD IS SOLVABLE
No timer, no move limit, no lives. Every level is machine-proved solvable before it ships, so a board that stalls was never unfair — the line you took was. Retry is free and unlimited, and when no pour is left the lab offers a spare tube: a few coins, or a short video instead. Never stuck behind a purchase.

440 CERTIFIED LEVELS
Eleven chapters, from five tubes and four colours up to twelve tubes and ten. Plus a Daily Experiment: one fresh certified board every day, with a streak that remembers.

BUILT TO BE READABLE
Colourblind mode marks the liquids with patterns as well as hues — a hatch, a weave, a scatter of dots. Big tap targets, no timers, no punishment for thinking.

MAKE IT YOURS
Earn coins by solving and spend them on tube glass and lab backgrounds. Skins and backdrops never make a level easier.

Free to play, with ads. Remove Ads is a one-time purchase; rewarded videos stay optional either way.
