How to play water sort

Tidetube is a water sort puzzle, also known as color sort or liquid sort: pour the colors between tubes until each tube holds just one.

Tap a tube, then the tube to pour into. The top color pours onto an empty tube or onto the same color, as much as fits. Sort the colors so every tube is full of one color.

Tips

  • Keep an empty tube free for as long as you can: it’s the only place to park a color that’s in the way.
  • Before pouring, look at what’s underneath. Uncovering a color that has nowhere to go can lock the board.
