Video: What would you do if you won the £168 million jackpot in tonight's Euromillions draw?
The biggest Lottery jackpot ever offered in Britain and Ireland could be won tonight.
No-one scooped Tuesday's record-breaking £167 million EuroMillions jackpot, meaning Friday's top prize of an estimated £168 million - subject to exchange rates - is still to be won.

The jackpot has now reached its maximum €190 million, where it will remain for a further four draws until it must be won on the fifth.
If a single ticket scoops the top prize, it would create the UK and Europe's biggest ever winner.
Players have been urged to buy their tickets early, with a 200% boost in sales expected for the draw.
Camelot has estimated that more than 26,000 tickets could be sold every minute in the hour leading up to the draw closing at 7.30pm.
As the jackpot is at its maximum, any money that would have boosted the top prize will now be shared among winning players in the next prize tier.
Andy Carter, the National Lottery's senior winners' adviser, said: "The extraordinary sum would be life-changing whether won by an individual or syndicate, and we have plenty of champagne on ice ready to celebrate.
"It would enable them to transform their life, as well as the lives of their friends and family, and we are ready to support them from the moment they claim."
He added: "This EuroMillions roll series has seen players raise an amazing £55 million for National Lottery Good Causes in just a month.
"This supports projects big and small across the country, including funding everything from local community projects to the nation's amazing Olympic and Paralympic athletes."
The current record holders are Colin and Chris Weir, from Largs in North Ayrshire, Scotland, who won £161 million in 2011.
According to The Sunday Times Rich List, a single winner scooping the entire £168 million jackpot would be richer than chef Jamie Oliver with his fortune of £150 million, multiple F1 world champion Lewis Hamilton with £131 million and singer Adele on £125 million.
