The Wand is a booster that you can only get in match-3 levels.
One Wand destroys one piece, or one obstacle layer (e.g., one chain out of two) without using a move.
When you want to use this booster, just tap the wand icon and then the tile you want to use it on.
This booster is very handy for getting access to hard-to-reach tiles, or for when you don’t have enough moves left to complete the level goals.
You can buy the Wand booster when you're already playing a level
