The Lawnmower removes pieces or one obstacle layer (e.g., one chain out of two) in a whole row without using a move.

To use this booster, tap the Lawnmower icon and then the piece that you want to use it on.

This booster is handy for removing many obstacles in a row all at once or when you don't have enough moves left to complete level goals.

You can buy the Lawnmower booster when you're already playing a level, get it as a reward for completing game days, or purchase it at the in-game Bank.
