There are still 21 missing millionaires from Friday's record-breaking Olympics lottery draw, Camelot says.
So far, 79 winners of the EuroMillions Millionaire Raffle draw have come forward to claim their £1 million prize - smashing the previous record of 25 millionaires made in one night on December 23 last year.
The National Lottery is still searching for 21 missing winners. One hundred ticket-holders each won £1 million in the special draw to mark the Olympics opening ceremony.
Tuesday's EuroMillions draw sees a massive £119 million jackpot. If one British ticket-holder were to win the lot they would be in second place in the National Lottery's rich list, Camelot said.
A National Lottery spokesman said: "Friday night was massive for the nation and was even bigger for our 79 new millionaires. We urge all players to check their tickets to help us push this record even higher.
"Tomorrow also promises to be an amazing night with a £119 million EuroMillions jackpot up for grabs.
"In addition to creating so many overnight millionaires, these big draws help boost the £30 million plus raised for National Lottery Good Causes by players every week."
Players can check to see whether they are a millionaire by going to www.national-lottery.co.uk or visiting any National Lottery retailer.
The map was commissioned to mark Tuesday night's EuroMillions roll-over which is now a staggering £138 million - the fifth biggest jackpot ever offered in the UK.</p>
Should anyone scoop the jackpot, their wealth will be slightly less than Europe's biggest Lottery winners Colin and Chris Weir, from Largs in Ayrshire. The husband and wife made the headlines in July when they won £161,653,000, thanks to several rollovers.</p>
Boasting 164 National Lottery millionaires, one in 14,211 North East residents has now banked a seven-figure jackpot prize. Winners Paul and Christine Goldie from Washington, near Sunderland, pocketed £3,581,481 after their numbers came up on Christmas Day last year.</p>
The Millionaire Map, which includes both publicity and non-publicity winners, is based on the number of millionaires created per adult population. One man who did go public with his winnings was Wayne Hughes from Holyhead on Anglesey, north Wales. The shop worker scooped £1,117,779 last August and even had the winning numbers tattooed on his arm.</p>
The region with the fewest millionaire jackpot winners was Northern Ireland, where only 53 seven-figure or more winners were created.</p>
Wales has seen 179 millionaires - one person in 14,502 - created over the last 16 years. Rugby fans Terry Roberts, Mike Williams, Lance Gifford and Gerwyn Jones, from the Rhondda Valley in south Wales, split £4,091,609 in April this year.</p>
