A calm liquid-sorting puzzle with 1,000 levels. No ads, no account.
Tap a tube to pick up its top colour, then tap another tube to pour. A pour works when the target tube has room and its top colour matches (or it is empty). Sort every tube to a single colour to finish the level. Undo and restart are always free.
Levels 1–600 and two hints per level are free. Chroma Flow Pro is a one-time purchase (no subscription) that adds unlimited hints, one extra empty tube per level and levels 601–1000. Levels you had already unlocked before version 2.1.1 stay open. If you bought “Remove Ads” earlier, you already own Pro.
