ITV News Correspondent Ben Chapman speaks to previous lottery winners about how the prize changed their lives.
On Friday night will be yet another chance to win the UK's biggest ever lottery jackpot - after nobody claimed the prize on Tuesday.
Britons had the chance to win a record Euromillions scoop of an estimated £184 million in the draw earlier this week. But nobody claimed the prize money, seeing it roll over.
A single winner would push the current British record holder - an anonymous £170 million winner in October 2019 - into second place.
Andy Carter, senior winners' adviser at The National Lottery, said he has seen all sorts of reactions in his 15 years dealing with lucky ticketholders - including some who have never told a soul.“I’ve seen people be sick with excitement, I’ve seen people resign their job on the spot, I’ve seen people jumping up and down, I’ve known husbands who haven’t told wives and wives who haven’t told husbands, I’ve been to homes where there’s literally a party going on already,” he said.
Why was Tuesday's jackpot different from others?
No ticketholder won the £174 million EuroMillions jackpot on Friday, causing the top prize to roll over into Tuesday's draw. Which has now rolled over again to Friday.
The EuroMillions jackpot will be capped once it reaches €220 million.
If a single person wins, they will become the biggest ever Euromillions winner on record, knocking an anonymous ticketholder in Switzerland off the top spot, who scooped €210 million in February this year.
Now nobody has won, the jackpot will stay at €220 million for a further four draws.
It must be won in the fifth draw, and if no ticket matches all five main numbers and two Lucky Stars, it rolls down into the prize tier where there is at least one winner.
That could result in many new multimillionaires.
What could a single ticketholder buy with the jackpot?
If one winner scoops the whole jackpot, they could count themselves richer than the singer Adele, whose net worth is £130 million, according to The Sunday Times Rich List.
A lucky winner could buy themselves a 110 acre private island in Thailand, off the coast of popular resort Phuket, for $160,000,000 (around £117,600,000) - and still have plenty of money left over.
Staying closer to home, they could afford to buy a house in each of the top 10 priciest streets in the UK, including in London’s Kensington Palace Gardens, where the average house price is nearly £30 million.
Multiple trips to space would even be possible, as a seat in Richard Branson's Virgin Galactic costs $250,000 (around £184,000).
The Lottery's Mr Carter said: “Specifically for large amounts of money, £184 million, it’s not just about making a difference to you or your family. If you want to, it can make a difference for generations and generations to come."
The adviser said some winners like to set up big charitable trusts, while others gift money to friends and family.
“Certainly lots of friends and family have benefited and whilst the National Lottery has made over 6,000 millionaires in 27 years it’s been in existence, there have been many hundreds of other millionaires that have been made by winners giving away millions of pounds,” he added.
Which countries are the luckiest in the Euromillions?
Since 2004, there have been more than 1,400 EuroMillions draws.
France has seen the highest number of winners with more than 833,000,000 lucky ticketholders.
The UK follows closely behind with at least 716,000,000 winners, while Spain comes in third with almost 613,000,000.
But the UK has the highest number of jackpot winners, claiming more than 22% of all jackpot scoops with 114 lucky ticketholders.
France and Spain follow very closely behind with 112 winners respectively, while Luxembourg is bottom of the league table with just three.
But Euromillions says: "It may be too simple to say that those countries which have had the most winners have actually been the luckiest.
"Luxembourg, for example, has only had three jackpot winners in comparison with France’s 109, but it also has the smallest pool of players because of its tiny population."
Meanwhile, the UK, France and Spain are the countries with the largest populations, so more tickets are sold in these locations - and all three have participated in more draws, it adds.
Despite the population size, Euromillions says the odds of winning are exactly the same regardless of where you play.
Who are the biggest Euromillions winners?
An anonymous winner in Switzerland bagged the biggest ever jackpot of €210 Million in February, the equivalent of almost £180 million.
This was less than three months after a ticketholder in France scooped €200 million in December 2020.In third place is Britain, with the country's biggest ever lottery winner, who received a jackpot of £170 million in October 2019, but decided to remain anonymous.
The second largest prize won in Britain went to Scottish couple Colin and Chris Weir in 2011, who received £161 million and spent some of their winnings on a £3.5 million mansion and cars. The couple split in 2019 and later that year Colin died after a short illness.
In 2012, Suffolk-based couple Adrian and Gillian Bayford won the second biggest jackpot in Britain of £148 million and used some of the winnings to buy a manor house for £6.5 million. They divorced 15 months after their win.
Frances and Patrick Connelly, from Northern Ireland, were lucky enough to win just under £115 million in the New Year’s Day jackpot in 2019. They celebrated by enjoying a cup of tea, after first believing their win was a scam.
The first thing the generous couple did was write a list of 50 people they would share their winnings with.
