How do I use in-game boosters?

There are four in-game boosters:

• Mallet clears a piece or an obstacle on the tile you hit.
• Magic Wand removes all drops that match the color of the drop you hit.
• TNT blasts an area of 7x7 squares on the board.
• Cross Rocket clears a row and a column.

To use them, you need to tap the booster icon and tap on the tile you want to use it on. If you accidentally tap on them and don’t want to use them, you can simply tap on an empty space outside of the board.

Using them doesn’t cost you a move.
