About Water Sort
Tap a tube, then tap another to pour the top color into it. You can only pour onto the same color or into an empty tube, and you win when every tube holds a single color. New daily puzzles appear at midnight Korea time: Easy (5 colors), Medium (8) and Hard (11), the same for everyone. Every puzzle is checked to be solvable.
Use undo, restart and hints, and turn on symbols if colors are hard to tell apart. The timer pauses when you lock your phone. Games and records stay in this browser; no account needed.
What if I run out of moves?
Undo a few moves or restart. A hint shows the next move that leads to a solution from where you are, or tells you if the position can no longer be solved.
