The Basket booster allows you to remove all pieces of one color without using a move.

When you want to use it, tap the Basket icon and then the piece of the color you want to remove.

This booster is handy for removing many pieces of the same color or when you don't have enough moves left to complete level goals.

You can buy the Basket 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.
