Instruction: 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 it 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.
