A very relaxing game : Sort all the same colored (4) balls as long as 4 same color balls to a specific tube.
- All the tubes word as stacks: the ball on top will be moved out first.
- Tap any tube to move the ball to lie on top of that tube.
- Any ball can be moved to an empty tube.
- A ball can be lied on top of the same color ball.
