Players across the country are being urged to check their tickets to see if they can claim the massive prize.
Andy Carter, senior winners' adviser at The National Lottery, said, "This year has been truly incredible for UK EuroMillions players - with four jackpot winners so far on these shores.
"Patrick and Frances Connolly from Northern Ireland won the £114.9 million EuroMillions jackpot in the draw on New Year's Day, Ade Goodchild banked £71 million in March and an anonymous ticket-holder bagged £35.2 million in April."
The winning main EuroMillions numbers on Tuesday night were: 25, 27, 39, 42 and 46.
The Lucky star numbers were 11 and 12.
The current record holders for the biggest ever lottery win are Colin and Chris Weir, from Largs in North Ayrshire, Scotland, who won £161 million in 2011.
The couple, who made a £1 million donation to the SNP, announced they were divorcing in April.
Adrian and Gillian Bayford, from Suffolk, took home more than £148 million in August 2012. They separated a year later.
