How to play Powerball

The Powerball costs $2 per play.

To play, select five numbers from 1 to 69 for the white balls, then select one number from 1 to 26 for the red Powerball.

You can choose your lucky numbers on a play slip or let the lottery terminal randomly pick your numbers.

To win, match one of the nine ways:

• 5 white balls + 1 red Powerball = Grand prize.
• 5 white balls = $1 million.
• 4 white balls + 1 red Powerball = $50,000.
• 4 white balls = $100.
• 3 white balls + 1 red Powerball = $100.
• 3 white balls = $7.
• 2 white balls + 1 red Powerball = $7.
• 1 white ball + 1 red Powerball = $4.
• 1 red Powerball = $4.

There's a chance to have your winnings increased two, three, four, five and 10 times through the Power Play for an additional $1 per play. Players can multiply non-jackpot wins up to 10 times when the jackpot is $150 million or less.

All prizes are set cash amounts, except for the grand prize. In California, prize payout amounts are determined by the sales and the number of winners.
