Perfect! All colors sorted!
Sort the colors. Master the tubes.
Spend your coins wisely
A free online color sorting brain puzzle — pour colored water between tubes until each tube holds a single color. Hundreds of levels, hints, undo, and a coin shop, playable free on mobile and desktop.
Tap a tube to pick up its top color, then tap another tube to pour it in. Sort every tube into one color to clear the level.
Clear near-finished tubes first, and keep an empty tube free as extra space when you get stuck.
Free to play? Yes, no download needed.
Stuck on a level? Use Hint, Undo, or buy an Extra Tube from the shop.
Works on mobile? Yes, fully responsive.
