Water Color Sort — Play Free Online

Water Color Sort drops you in front of a row of glass tubes, each one part-filled with layers of colored water. Nothing else is moving on the screen — no timer, no enemies, just tubes and colors and the decision of which one to pour next. It sits next to skribbl.io on this site as the exact opposite pace: instead of racing a clock to draw or guess a word, you get all the time you want to think one move ahead.

Every tube starts as a stack of colors dropped in seemingly at random, with a few tubes left empty as breathing room. The goal is simple to state and harder to execute: end with every tube holding a single color from top to bottom, or empty. Getting there means reading the whole board before you touch anything, because a careless early pour can trap a color at the bottom of a tube you can no longer reach.

How to play

Click or tap a tube to pick up the water sitting on top of it, then click or tap a second tube to pour it in. A pour only goes through under two conditions: the receiving tube is empty, or the color already on top of it matches the color you're carrying. If neither is true, nothing moves and you try a different pair. Because only the top layer pours, and only as much of it as the target tube has room for, one move might empty a tube, split a stack in half, or finish a color completely — reading how much space is left matters as much as matching the color.

Tips

• Clear the easy matches first. Tubes that only need one or two pours to become a single color free up options for the harder stacks later.
• Keep at least one tube empty for as long as you can. It's your only tool for temporarily parking a color you don't have a home for yet.
• Before you commit to a pour, check whether it buries a color underneath one you still need — undoing that later almost always costs more moves than it saved.
• When several tubes are jammed against each other, work on whichever color has the fewest scattered layers first. It's usually the quickest one to finish and clears a tube for everything else.

For something else that's quiet and puzzle-minded, Draw Pixel Art turns coloring into a numbered logic puzzle instead of a pouring one, while One Line Draw asks for a single unbroken stroke through a shape — a different kind of one-tool constraint. If you'd rather trade quiet sorting for chaos, Smash Karts is a multiplayer kart battle on the same site with no relation to tubes or colors at all.

Water Color Sort works well as a five-minutes-before-something-else game. Pick it up on a touchscreen or with a mouse, clear a level or two, and put it down — each puzzle is self-contained, so there's nothing to lose by stopping.
