HOW TO PLAY:

• Tap any tube to move the ball lying on top of any tube into another tube

• The rule is that you can only move a ball on top of another ball if both of them have the same color and the tube you want to move into has enough space. Otherwise the ball is rejected.

• You can always restart the level at any time or retrace your steps one by one using the back button.

• Stack all the balls with the same color into a single tube.

• If you get really stuck you can add a tube to make it easier.
