A 34-year-old man from Southampton plans to enter the housing market after he scooped a whopping £245,000 when he went through the card at Wolverhampton on Wednesday.
The motor mechanic, who wishes to remain anonymous, picked all seven winners in an accumulator bet after placing a £30 bet with William Hill.
The married punter with three children intends to buy a first home with his winnings.
He said: "I chose the horses based on their names.
"I looked at ones who were favourites and selected them at random based upon names that I liked.
"I was watching the results come in and after the first three had won, I started texting the wife.
"When the seventh had won, I was jumping around the place. It's the biggest high I have ever had.
"I'll be working this weekend and I don't plan on telling many people, else they'll all be wanting discounts!"
