Once the competition is under way, you can start collecting bolts in match-3 levels by detonating explosive power-ups: Firecrackers, Bombs, Dynamite, and Warheads (bigger power-ups earn you more bolts). Detonate several power-ups at the same time to get more bolts.
Keep in mind:
- Bolts only count on levels you beat.
- You can't collect bolts on event levels (only regular levels are eligible).
- Lightnings and Energy Blasts don't earn you bolts.
