Water Sort - Collections

Grab a tube, tip it, and watch a stream of colored liquid slide into the next one until the colors line up - that's Water Sort - Collections in a nutshell. You're staring at a rack of tubes filled with jumbled layers of color, and your only job is to pour until each tube holds just one shade from top to bottom.

It sounds simple, and the first few pours are. Then a tube fills up one color short of finished and you realize the only free space is blocked by the wrong shade three tubes over. That's when the relaxing puzzle turns into a genuine little logic problem, and you'll find yourself planning three pours ahead instead of just clicking around.

The "Collections" part means there's more sorting ahead once you clear a set, so you're never stuck staring at one solved rack for long. It plays straight in your browser on desktop or mobile, no download, so you can pour a few tubes on your phone in a waiting room or spread out on a bigger screen at home.

If color-matching puzzles are your thing, this sits nicely alongside other Puzzle games and Mechanics games on the site - all quick to pick up, all built around that one satisfying click of pieces falling into place.

Sort every tube so it holds a single color from top to bottom, with no colors mixed together. Pour liquid from one tube into another by selecting a tube and then the tube you want to pour it into - a pour only works if the top color matches or the target tube is empty.

On desktop, click the tubes to select and pour; on mobile, tap them the same way. Keep at least one empty tube open as often as you can, since it's your only real breathing room when a color gets boxed in.

Work from the top layers down and don't pour just to feel productive - a wasted pour can lock a color behind the wrong one and turn an easy tube into a real headache.
