Normally the EuroMillions UK Millionaire Maker guarantees one winner of £1 million for each draw.
But tomorrow night that number is being boosted by 39.
The money will not be taken from the estimated £34million jackpot.
Andy Carter, The National Lottery’s senior winners’ adviser, said: “We literally have a truck load of champagne on ice ready to help the lucky 40 ticket-holders from all over the UK celebrate their life-changing win.
“We’re urging all EuroMillions players to get their tickets as soon as possible in order to be in with a chance of being one of the lucky forty guaranteed millionaires.”
Tickets can be bought online from 8am to 11pm tomorrow.
Camelot confirmed that it’s possible to win both the jackpot and the UK Millionaire Maker on the same ticket.
To win the jackpot you need to match five main numbers and two Lucky Stars, but you will get a payout for matching anything more than two.

Earlier this year, lottery organisers Camelot came under fire for slashing the amount of Millionaire Maker prizes from two to one every draw.
The changes followed a strategic review from the company as the number of players continues to decrease.
The firm said said it would be running more special draws for its EuroMillions game and is making the changes to account for this.
A EuroMillions ticket costs £2.50 and includes automatic entry into the UK Millionaire Maker draw.
“Make sure you get a ticket”
The National Lottery has created more than 4,750 millionaires or multimillionaires since launch in 1994, and has also paid more than £65billion in prize money.
Changes to the EuroMillions in 2015 saw the cost of playing increase by 50p to £2.50 a line and players had to choose from an extra number that decreased the odds of winning.
Daily Star Online previously revealed how leaving the EU will affect those playing the EuroMillions.
A spokeswoman for Camelot told Daily Star Online: “The reason we’re doing this is because sales on EuroMillions – and therefore the amount of money the game raises for Good Causes – are driven by the big, rolling jackpots, as well as special draws in which lots of guaranteed £1 million UK winners are created.
“These special draws build huge levels of player excitement and typically generate over 60% more in sales when compared with an equivalent draw, so are great from a Good Causes perspective.”
