What if you have just the Powerball number?

If you only have the Powerball number and none of the drawn white ball numbers, your chances of winning a prize are limited. You may still win a small prize if that Powerball number matches the drawn Powerball, but it won't be a jackpot win. The amount you win depends on the specific rules of the game and the prize tiers set for that drawing. Overall, having just the Powerball number is unlikely to yield significant winnings.
