Combining special pieces helps you clear more tiles and produce bigger explosions. Here are the combinations that are currently in the game:

🔸 Rocket + Rocket removes all pieces in a square area around it, creating 3 Rockets that home in and remove 3 random goal pieces.

🔸 Rocket + Sweeper / Bomb removes 4 pieces adjacent to it, then homes in on a random target piece and activates a Sweeper / Bomb at its position.

🔸 Sweeper + Sweeper removes one row and one column of pieces regardless of which way the Sweepers were facing.

🔸 Sweeper + Bomb removes three rows and columns of pieces.

🔸 Bomb + Bomb activates a Bomb with double the action radius.

🔸 Pinwheel + Rocket / Sweeper / Bomb makes the Pinwheel turn all the pieces of one type (the one currently the most common on the field) into respective special pieces.

🔸 Pinwheel + Pinwheel removes all pieces from the field, clearing one obstacle layer in the process.
