This week's Euromillions jackpot could change one lucky winner's life for good.
With a massive £107million up for grabs this Friday, February 4, you've got to be in it to win it.
Not only that, but the National Lottery has reached a 'must win' stage with the prize totally a huge £11.8 million.
As no one won Wednesday night's quadruple rollover draw, Saturday's Lotto could be a 'Jackpot rolldown' which means the prize must be won.
This means that the prize will go to a player matching all numbers or will be shared between lucky runners up.
How to play Euromillions
To enter you must pick five numbers between one and 50 as well as two Lucky Stars between one and 12.
You can pick the numbers yourself - whether you opt for lucky numbers of birthdays of loved ones - or you can play using a Lucky Dip where numbers are picked for you at random.
It costs £2.50 per play.
Draws are made on Tuesdays and Fridays at 8.45PM.
However, you must purchase your ticket by 7.30PM on the day to be in with a chance of winning.
How to play National Lottery

Again, you can manually select your numbers each time you play or opt for a Lucky Dip so your numbers are chosen at random.
It costs £2 per entry.
National Lottery draws take place on Wednesday's at 8pm and Saturday's at 7.45pm.
Camelot's Andy Carter, senior winners' adviser at The National Lottery, told The Mirror : "It promises to be an amazing Lotto draw on Saturday with a whopping £11.8m 'must be won' jackpot up for grabs.
"In a 'must be won' draw, if the jackpot isn't won, the prize amount is shared out amongst the other prize tiers, meaning lots of players could win lots more."
