£148m Lottery jackpot has to be won
A single winner of tonight's EuroMillions draw would scoop the second-largest jackpot yet.
The prize fund has been capped at 190 million euro - meaning a UK ticket-holder would win £148 million.
It would be the largest pot since Colin and Chris Weir, from Largs in North Ayrshire, won £161 million last July, with the difference in the exchange rate meaning this week's jackpot is slightly less than that.
If no one matches all five numbers and two lucky stars, the prize rolls down to those matching five numbers and one star. The last time the jackpot was passed down in that way, seven UK players won £6.7 million each.
A EuroMillions spokeswoman said: "This is it - the jackpot has to be won and it promises to be an amazing night. We urge all players to get their tickets early.
"Only a couple of weeks ago, we created 100 millionaires in one night and this draw could be another golden night with the potential for several multimillionaires to be made here in the UK on Friday.
"In addition to the chance to win a life-changing prize, these big draws boost returns to National Lottery Good Causes, with players helping to raise over £30 million every week."
Once the jackpot has reached the cap - which it did in Tuesday night's draw - it can only roll over once before it has to be won.
A single winner would be able to buy enough gold to cast 33,000 Olympic gold medals, Camelot said. They would also have a fortune bigger than that of Sir Tom Jones, which is £140 million, according to the Sunday Times Rich List.
Camelot is still looking for a UK ticket-holder who is yet to come forward to claim a £63.8 million EuroMillions prize after hitting the jackpot on June 8. The owner of the ticket, which was bought in the Stevenage and Hitchin area of Hertfordshire, has until December 5 to pick up the prize.
