Hardness

Move on - easy to say, hard to do!

It's all about the collision

It's challenging

It's a time-killer

It's strategic

and ... it's hard ...

3 Modes:

Rubber: The easiest. a warm up. just swipe the bubble and group all same colors

Stone: Harder. It's elastic, bubble will be pushed when collide

Diamond: The hardest. Place the bubbles on the targets and group the others!
