A lottery player in the US state of Maryland said a "mistake" he made while buying his Keno ticket led to his winning a $32,000 prize, UPI reports. The Baltimore man told Maryland Lottery officials he was at North Point Liquor & Bar in Baltimore when he decided to buy a 10-spot Keno ticket for 10 games, and ended up shocked when the bartender told him the price of adding the Bonus option. "She said, 'This is $40. Do you want to keep it?' I said, 'Go ahead.' I always keep my mistake tickets," the man said. The man's numbers started appearing during the fourth draw. The man scanned his ticket and discovered the Bonus option had delivered a big win. The winner said his prize money will go into his bank account for safekeeping.
