If you saw two boosters next to one other, you probably know those can produce some fantastic effects.
Let’s break down those matches:
Rocket + Rocket = blasts an entire row and column from the tapped tile's location.
Rocket + Bomb = blasts three rows and columns from the tapped tile's location.
Rocket + Spray Can = changes all Cubes of the Spray Can’s color into Rockets and detonates them.
Bomb + Bomb = creates and detonates a giant Bomb that blasts everything within a 7x7 radius.
Bomb + Spray Can = changes all Cubes of the Spray Can’s color into Bombs and fires them.
Spray Can + Spray Can = blasts the entire board.
Pro tip: Your Power Bar will fill faster when you tap on the combo of two or more boosters.
