It's a fun water-sorting puzzle game that can be played online or offline. There are tons of water-sorting puzzle games for free, but this one is special.

If you're not familiar with water-sorting puzzle games, they're a little like those mahjong games, but there are no hints. There are no time limits and no pressure.

The goal is to fill the cup with one of the four colors of water. You can only use one of them at a time.

The way to fill the cup is to sort the water into the right color.

If you're not sure about how to do that, there is a handy sort guide that will help you.
