How to play Water Sort

The goal

Pouring

• Tap a tube to pick it up, then tap another tube to pour into it. You can also drag from one tube to the other.
• Only the top color pours, and all of that color sitting together on top goes at once, as much as fits.
• You can pour into an empty tube, or onto the same color. A tube holds four units.
• Tap the picked-up tube again to put it down. Each color has its own symbol, so you never have to tell colors apart by shade alone.

Getting unstuck

• Undo takes back pours one at a time, as many as you like.
• Once per level you can add an extra empty tube.
• Hint shows a pour that leads to a solve. If there is no way to finish from where you are, it tells you to undo.
• On a computer: arrow keys and Space, or the number keys, pick tubes. U or Ctrl+Z undoes, H hints, T adds a tube, R restarts.

Levels

• There are 200 levels, starting with 3 colors and building up to 12. Every level always deals the same puzzle, and every one has been checked by a solver to be solvable.
• Clearing a level unlocks the next. The Levels button lets you replay any you have reached, and your best time and fewest pours on each are saved.
• The clock starts with your first pour. Finishing without the extra tube or hints scores a bonus.
