Lotto Must Be Won Draws

Lotto Must Be Won draws guarantee that the jackpot prize money will be given away, boosting the payouts for thousands of winners and making for some exciting draws. Find out all about Must Be Won draws and Rolldowns on this page.

What is a Must Be Won draw?

A Must Be Won draw occurs after the Lotto jackpot has not been won for five consecutive draws. In the sixth draw – which is the Must Be Won draw - the jackpot prize money has to be won, even if no one matches all six winning numbers.

If at least one player does match six numbers in a Must Be Won draw, they will win the jackpot just like in any standard draw. If no one manages to match six numbers, however, the jackpot prize money will be shared between all the other players who match two or more numbers, in what is known as a ‘Rolldown.’

After a Must Be Won draw, the Lotto jackpot always resets to its starting value of £2 million for a Wednesday draw or £3.8 million for a Saturday draw.

Rolldown Prizes

If a Rolldown occurs, the jackpot prize money is split between all other winners according to certain percentages.

The following table shows the percentage of the jackpot that will be allocated to each prize category if no tickets match all six main numbers in a Must Be Won draw. You can also see the most recent Rolldown prize amounts:

Prize Tier Percentage of Jackpot Regular Fixed Prizes *Rolldown Prizes ()
Match 5 + Bonus 3% £1 million
Match 5 5% £1,750
Match 4 7% £140
Match 3 85% £30
Match 2 - Free Lucky Dip £5 + Free Lucky Dip

Match 2 winners are awarded a fixed £5 prize on top of the free Lucky Dip they would ordinarily receive. The money needed to pay the £5 prize is taken from the rolled down jackpot before the remaining funds are split according to the percentages shown in the table. The exact prize amounts for the Match 3 tier up will vary depending on how much the jackpot is worth and how many winners there are in each tier.

Previous Lotto Jackpot Caps and Rollover Limits

The current format is just one of many that have been used for Lotto since the game’s launch. Must Be Won draws have been used in the past, although with different rules on when they were used, as well as jackpot caps that limit the top prize to a specific value. Here’s how the rules around rollovers and the jackpot cap have changed over the years.

November 1994 – National Lottery Launched
When the National Lottery was launched, there was initially a rollover limit in place rather than a jackpot cap. Under the original rules the jackpot could only roll over four times before it had to be won.

Must Be Won draws occurred only a handful of times in the 20 years that the original ruleset was in place. The biggest Rolldown happened in the draw on 17th December 2014, when a jackpot of £15 million was shared between five players who matched five numbers plus the Bonus Ball. They received just over £3 million each.

October 2015 – Jackpot Cap Introduced
Big changes were introduced to Lotto in October 2015, including the addition of 10 extra numbers and a new jackpot cap of £50 million. The cap replaced the previous limit of four rollovers and rules stated that the jackpot could roll over any number of times until someone won it or it surpassed the £50 million threshold. Only one more rollover was allowed after the jackpot reached this amount, and then it had to be won.

November 2018 – Launch of New Must Be Won Format
A five-rollover limit was introduced in November 2018 to ensure the jackpot would be won more regularly, with the new rules marking the first time in National Lottery history that funds would roll down between multiple prize tiers if the jackpot was not won. The National Lottery also began to hold special Must Be Won draws, in which the jackpot would be increased to a guaranteed amount, such as £15 million or £25 million, and the entire amount had to be won in that draw.

November 2020 – £5 Rolldown Prize Introduced for Match 2 Winners
The National Lottery introduced a new £5 prize for any players that match two numbers when the jackpot rolls down in a Must Be Won draw. The £5 prize is fixed and is awarded on top of the free Lucky Dip that winners in that tier ordinarily receive. The percentage of the rolled down jackpot allocated to the other prize tiers was updated in order to fund the £5 prize.
