A Manx-based online betting company's paid out £50,000 to a postman from Sunderland - after his flutter on the Premier League came in at 5,000 to 1.
26-year-old Ben Scott saw the odds on his £10 bet boosted by Onchan-based Betstars under a special promotion.
He bet on Chelsea to win the Premier League before the start of the season, when the company was offering the same odds as Leicester winning last year.
He says his win hasn't sunk in yet - but the first thing he'll do with his winnings is take his family for a meal.
