Bubble PopperG 10

Welcome

This should come naturally if you are playing the game but if you really want to grind this out really fast then level 5-4 is the best place to do this.

On this level there 10 bubbles and you only have explosive birds, Just shoot the first bird at the small rocks on the bottom and explode it and you should get 7-9 bubbles popped each time on 4 sec, Then restart the level rinse and repeat.
