The winning Powerball numbers for Saturday, September 23, 2023, are 1, 12, 20, 33, 66, and the Powerball number is 21. However, it is important to note that these numbers are from a past drawing and are no longer valid for future drawings. The Powerball website states that drawings are held every Monday, Wednesday, and Saturday at 10:59 pm ET at the Florida Lottery draw studio in Tallahassee. To play Powerball, you need to select five numbers between 1 and 69 for the white balls, then select one number between 1 and 26 for the red Powerball. You can choose your numbers on a play slip or let the lottery terminal randomly pick your numbers. The Powerball costs $2 per play, and for an additional $1 per play, the Power Play feature can multiply non-jackpot prizes by 2, 3, 4, 5, or 10 times.
