A tube-pouring puzzle where layers come in different thicknesses and each level adds more colors to sort.
Color Pour Sort gives you a row of glass tubes, each holding stacked bands of colored liquid, plus a bit of empty space to work with. Your job is to pour from one tube to another until every color sits alone in a tube of its own.
The twist is that the bands are not all the same size. Some layers are thin and some are thick, and a pour only moves as much liquid as the target tube can hold. That small rule turns a simple sorting task into a real planning puzzle.
Rules in brief
Tap or click a tube to lift it, then pick the tube you want to pour into. Only the top color moves. You may pour it onto a matching color or into a tube with nothing in it. Try to mix two colors and you see a “Cannot mix” note, and a tube with no room shows “Bottle full”.
If the top layer is bigger than the free space in the target, part of it pours across and the rest stays behind. Once a tube is filled to the brim with one color, a black cap locks it so it can no longer be poured from or into.
How the levels grow
There is no last level. The count begins with two colors spread over four tubes. As the number climbs, more colors join, so high-numbered boards bring extra tubes and lots of slim bands.
The menu holds a few extras. You can turn on dark mode, make the tubes smaller, slow down or skip the pour animation, pick one of three level generators, or type in any level number to jump there. With the same generator, one number gives you one fixed board, which lets you return to a layout you enjoyed.
Winning moves
- Hold on to an empty tube for as long as possible. It is the only safe place to park a color that matches nothing.
- Check the free space before you pour. A partial pour leaves a sliver behind that can bury the color under it.
- Finish and cap tubes early. A capped tube is out of the way and gives you less to track.
- Treat undo as a free test. Try a short line of pours, and rewind if it leads nowhere.
Who it suits
This is a calm, quiet puzzle, and because your place is saved, it works well for short breaks. You can stop after a single level or keep going for a long streak. Players who like thinking a few moves ahead will enjoy the later levels most, where one careless pour can tie up a whole board.

Color Pour Sort FAQ
Does Color Pour Sort save my progress?
Yes. Your level number and the state of the tubes after your last pour are kept in your browser. If you leave partway through, you come back to the same spot. Clearing your browser data will erase that save.
Can I play it on a phone or Chromebook?
Yes. Everything works with a tap or a click, and the tubes shrink so the whole level stays on the screen. It runs in either orientation, and a settings option makes the tubes smaller if a later level feels crowded.
How do I know when a level is finished?
A tube that is full to the top with one color gets a black cap. You clear the level once no tube holds mixed colors, meaning each one is capped or has nothing in it. A brief cheer pops up and the next numbered board follows.
What should I do when I get stuck?
Use the curved arrow to undo pours one at a time and try a different order. The circular arrow restarts the level, and pressing it a second time before you pour again restores the layout you had before restarting.
