This is a fun and addictive puzzle game! Sort the colored balls in the tubes until all of the same-color balls are in the same tube. A brain-teasing game that is both tough and relaxing!
Just tap the balls and switch the same balls to tubes and make them sort correctly. 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. It's easy to learn with endless challenges.

How to Play:
- Tap any tubes to pick a ball
- Put it into a tube that contains the same color ball on the top of the tube that has enough space, or an empty tube.
- Stack all the balls with the same color into a single tube.
- Try not to get stuck! But you can undo the ball move by using the back function or restart the level anytime you want.
- Don’t forget you also can add an empty bubble tube to make the game easier
