A man in Britain placed a one-pound bet and won a mind-boggling 353,000 pounds, a media report said.
Bookies William Hill said the man bagged 353,000 pounds after winning a seven-horse accumulator bet.
The man has not worked in past five years after undergoing a heart surgery.
"I'm shocked. I regularly place these little bets and everyone tells me I'm mad. I've hit the bar a few times but this is incredible," the Daily Telegraph quoted the winner as saying.
"My brain was a wreck and I couldn't understand the balance on my account. I first thought it would pay about 21,000 pounds and had to get my son to come and translate that the numbers meant I'd actually won 353,000 pounds."
He now plans to buy his own home and visit his sisters settled abroad.
A spokesman for William Hill said: "He's our luckiest ever punter."
