What happens when I combine power-ups?

When two power-ups are next to each other, swap them to activate a combination. Each pair has its own effect:

Combination	Effect
Rocket + Rocket	Blasts one row and one column.
Bomb + Rocket	Blasts three rows and three columns.
Bomb + Bomb	Explodes over an area of up to 7×7 cells.
Fish + Bomb or Rocket	Carries the Bomb or Rocket to the Fish’s target, then activates it there.
Fish + Fish	Sends out three Fish when the Double Fish booster isn’t active.
Plasma Ball + Rocket, Bomb, or Fish	Turns all pieces of one color into that power-up, then activates them.
Plasma Ball + Plasma Ball	Hits every cell on the board.

If two power-ups are close but not touching, look for a way to bring them together before setting either one off.

A Fish combination can deliver a Bomb or Rocket to a distant target. On a crowded board, combining a Plasma Ball with a Bomb or Rocket can affect a large area at once.
