3 stars for lower levels..

[aliadri22]

I can't seem to get 3 stars on easy levels like 5 & 6 :(

what is the best way to get a higher score?? using the least or the most amount of balls? or maybe its making the most bubbles drop instead of pop?

I'm not sure what I'm doing wrong.

Keep in mind that you get more points by making the bubbles drop than you do by popping them.
