The Rocket power-up clears the vertical line of blocks. It also clears one layer of blockers. The exceptions are:
- Locks
- Hives (if there's honey around it)
- Candles (rocket can light them up, but not remove them)
- Boxing bags (rocket hits them once but doesn't remove them)
- Closed oysters
- Bowling balls and pins
To use the Rocket, tap the Rocket button and then tap the column you wish to clear.
