At a glance
- Must Be Won applies when the UK Lotto jackpot hits its cap: that evening the jackpot has to be paid out, either to a Match 6 winner or, failing that, rolled down to the lower tiers.
- It last rolled down on 18 July 2026: nobody matched 6 in either round, and Match 3 paid £24 instead of £10, Match 2 £5 instead of £1.
- Rollovers are the norm: since 2015 the jackpot is won on only 16% of draw nights, which is why the cap gets reached.

Overview
Must Be Won is a UK Lotto rule that applies when the jackpot reaches a set cap. The next draw must pay out the jackpot. If no one matches all 6 numbers, the jackpot money is shared among lower-tier winners (Match 5+Bonus, Match 5, etc.) according to the rules.
So on a Must Be Won evening, the jackpot pool is always won—either by Match 6 winners or by redistribution to other tiers.
Since 10 June 2026 the rule applies to the evening as a whole: the jackpot is only redistributed if neither Round 1 nor Round 2 produces a Match 6. This happened on 18 July 2026, when the jackpot pot was redistributed down to the lower tiers (Match 3 paid £24 and Match 2 paid £5, instead of the usual £10 and £1).
Your odds do not change. A Must Be Won draw does not improve your chance of winning.
Important
If no one matches all 6 across either round of a Must Be Won evening, the jackpot is shared among Match 5+Bonus, Match 5, and possibly other tiers. The money is always paid out.
When does it trigger?
It triggers when the jackpot hits the cap defined by Allwyn. The cap can change; check national-lottery.co.uk for the current threshold. Once reached, the following Wednesday or Saturday draw is a Must Be Won draw.
How the money is shared
If no one matches all 6 on a Must Be Won draw:
- The jackpot pool is added to the prize fund for lower tiers
- It is distributed according to the game's rules—often to Match 5+Bonus, Match 5, and possibly others
- Winners in those tiers receive larger payouts than usual
The exact distribution is set by the operator. The important point: the jackpot is always paid out on that draw.
Your odds do not change
A Must Be Won draw does not improve your chance of winning. Your odds per line are the same as any other draw. The only difference is that the jackpot is guaranteed to be won—so either someone hits Match 6, or the money goes to other tiers.

FAQ
How often does Must Be Won happen?
It depends on how often the jackpot rolls over and reaches the cap. There is no fixed schedule.
What is the current jackpot cap?
Set by Allwyn and subject to change. See national-lottery.co.uk for current rules.
Can I win the full jackpot on a Must Be Won draw?
Yes. If you match all 6 numbers, you win (or share) the jackpot as usual. Must Be Won only affects what happens if no one matches 6.
Do Match 5 winners get more on Must Be Won?
Often yes. When the jackpot is redistributed, lower-tier winners typically receive larger amounts. The exact split depends on the rules.
Does Must Be Won change the draw schedule?
No. Draws still take place on Wednesday and Saturday. Only the jackpot rules change for that specific draw.
Has a Must Be Won evening with no jackpot winner actually happened?
Yes. On 18 July 2026, the pot was redistributed down to the lower tiers: Match 3 paid £24 and Match 2 paid £5, instead of the usual £10 and £1.
