Here are some ways to earn additional points that will help you to earn more points:
- Combos
- Hitting Flowers
- Gap Bonuses

In order to achieve combo, you need to destroy the set of marbles and after that, before your next shot, another set (or more of them) should be automatically destroyed when marbles collide to close the gap.
Flowers will appear around the board while you play. Hit them with marble in order to get some extra points.
To get extra points for Gap Bonus you need to create the gap in the chain and destroy the marbles by shooting through that gap. The smaller the gap is - the more points will be added.
