You can use one Power-up in a turn and up to three Power-ups per game. You’ll be dealt three at the start, and can buy additional Power-ups in the Power-up Store (via the yellow Power-up Store button). To deploy a Power-up, simply tap on the Power-up first and then follow the instructions. You can “Undo” certain Power-ups within your turn, while others will be consumed upon use. Click on the Information Icon in the top right of any Power-up to learn more about what each Power-up does!
