One ticket sold in Arkansas matched all five numbers, but did not match the Megaball number. That winning ticket is worth $3 million because the person who purchased the ticket purchased the “Multiplier” option which tripled the $1 million prize.

The Powerball numbers drawn Saturday were 11-14-32-43-65 and the Powerball was 15. The Power Play was 3. Two players – one in Nebraska and one in Michigan – matched the five numbers, but not the Powerball number. Each of those tickets is worth $1 million.
