Power Ups are generated by daubing 3 spaces inside a bingo room. When a power up is generated, you can tap the power up on top of the Power Up Meter to activate it and apply its effect to your cards.
You can also turn on auto power ups by tapping the toggle below the Power Up Meter. This will automatically activate power ups when they are generated.
Some power ups can only be activated once per round while others can be used multiple times. If you see a message appear reading “No Inventory” above a power up. That means there are no more power ups that can be played during this round.
