This number is selected at random and will be either 2, 3, 4, 5 or 10. When the Powerball drawing takes place, a Power Play number is also announced.
It costs an extra $1 per play, so you would have to pay $3 in total if you were buying a single line of numbers, $6 for two lines, and so on.
However, you need to opt in to Power Play when you buy your ticket by marking the relevant box on your playslip. Power Play is a multiplier which is applied to any prizes you win apart from the jackpot.
