Column Blaster is a booster in Pet Rescue Saga. It is unlocked at level 17.
Description[]
Use a Column Blaster rocket to clear a row of blocks, cages and pet carriers!
Properties[]
The column blaster has you select a vertical column. A rising rocket then clears blocks and most other obstructions from that column. Note that the in-game description is actually incorrect because it says it clears a horizontal "row".
