What do all the various boosters do and how do I get them?

Rocket: Pop 5-6 matching balloons at once to get a Rocket booster. Rockets will clear an entire horizontal or vertical line of balloons. They change direction after every turn so pay attention to where they’re pointing and use them strategically!

Bomb: Pop 7-8 matching balloons at once to get a Bomb booster. Bombs will clear a 5 x 5 diamond of balloons.

Laser Gun: Pop 9 or more matching balloons at once to get a Laser Gun booster. The Laser Gun clears all balloons of one color.

Note: You can mix boosters together for different effects. Experimentation is key!
