Yaowaluck Nakkong also became the biggest bingo winner that the Winners Club, in Bury St Edmunds, had ever seen.
Amazingly though, the 53-year-old Thai grandmother-of-one, who has lived in the UK for six years, didn't initially realise just how much she had scooped.
"I don't think she fully understood at first how much she had won, as her English is not that good," said the club's manager, John Markerson.
"It was phenomenal stuff. Although this was by far our biggest win on the National Game, we have been very lucky with quite a few zone prizes recently."
Ms Nakkong, who said that she was "very, very happy" with her win, now plans to go on holiday for four weeks, as well as clear the mortgage on her home in Thailand.
