The three fixed prize tiers, before and after the change. Match 5 fell the furthest, from 1,750 pounds to 1,000.
What changed, and when
The rules changed on 7 June 2026 and the first double draw ran on Wednesday 10 June.[1] You still pick six numbers from 59. The ticket still costs two pounds. Draws are still Wednesday and Saturday.
What is different is that two sets of numbers now come out on each draw night, from two different machines. Your single line is checked against both. You can win in Round 1, in Round 2, or in both.
Twice the chances, smaller prizes. That is the trade
Each round is a straight 6 from 59, which is 45,057,474 combinations.
Two independent rounds means the chance of missing in both is the chance of missing one, squared. Work it through and the chance of hitting the jackpot on a given night is 1 in 22,528,737.[2] Almost precisely double, and not quite exactly, because the vanishing chance of winning both rounds at once has to come off.
The operator's own headline is that any prize improves from 1 in 9.3 to 1 in 4.9. That checks out: two independent rounds at 1 in 9.3 each gives 1 in 4.91. They expect Lotto millionaires to rise from around 140 a year to roughly 345.[1]
But prize money has to come from somewhere, and the ticket price did not rise. So it came out of the fixed tiers.
| Tier | Before 10 June | After |
|---|
| Match 2 | Free Lucky Dip | £1 cash |
| Match 3 | £30 | £10 |
| Match 4 | £140 | £50 |
| Match 5 | £1,750 | £1,000 |

You hit those tiers about twice as often now, and collect roughly a third to a half as much each time. On the small prizes the two effects substantially cancel. Match 2 is the exception and a genuine gain: a free ticket became a pound in your hand.
The last time the UK moved the numbers
In October 2015, Lotto went from 6 from 49 to 6 from 59. Ten extra balls.
That sounds modest. It took the jackpot odds from 1 in 13,983,816 to 1 in 45,057,474, which is 3.2 times harder, overnight.[2]
Players were not pleased, and the reaction was loud enough to become a story in its own right. There were petitions. Sales of Lotto fell. The game had made its top prize dramatically harder to win, and the justification at the time was bigger, more exciting rollovers.
Ten and a half years later the same game, now run by a different operator, has spent a format change buying some of that back.
Why that story matters
Because it shows what these changes actually are. Not improvements or degradations, but a dial.
In 2015 the dial went one way: fewer winners, bigger jackpots. In 2026 it went the other: more winners, smaller prizes. Same game, same six numbers, opposite directions, both announced as good news for players.
And here is where the two land relative to each other.
| Era | Format | Chance of the jackpot, per night |
|---|
| 1994 to 2015 | 6 from 49, one draw | 1 in 13,983,816 |
| 2015 to June 2026 | 6 from 59, one draw | 1 in 45,057,474 |
| From 10 June 2026 | 6 from 59, two draws | 1 in 22,528,737 |
Two rounds have not undone 2015. A night of Lotto today is still 1.6 times harder than it was under the old 49 ball game, and you are winning smaller amounts at the tiers below. The 2026 change recovered about half the ground the 2015 change gave away.
That is not an argument against it. It is simply what the numbers say, and nobody else is putting the two changes side by side.
What this does to the numbers on this site
Our UK Lotto frequency charts and shape readings count both rounds. They are genuine draws, same pool, same machines, so ignoring Round 2 would throw away half the evidence.
It means a draw night now contributes twelve main numbers to the pool instead of six. If our UK counts look different to a site tracking only Round 1, that is why.
We checked the two eras against each other before pooling them and they are statistically indistinguishable, which is what you would expect from the same game drawn more often. That is the test that matters: a format change would have failed it, and this is not one. The matrix did not move. Only the number of draws did.
The straight version
Two things are true here at once, and most coverage picks one.
Your chance of winning something did roughly double. The prizes you are now twice as likely to win are meaningfully smaller. The National Lottery traded prize size for prize frequency, said so plainly, and the arithmetic backs it up in both directions.
Whether it is an improvement depends on what you were buying the ticket for. If it was the daydream, you now get two a night. If it was the occasional fifty quid back, you are getting it more often and enjoying it less.
And if you played through 2015, it is worth knowing you are still not back where you started.
Correct as at 15 August 2026. Odds are computed from the 6 from 59 matrix rather than quoted, and the combined figure assumes the two rounds are independent, which is how the game is described. Prize values are as published by the operator at the change; always confirm current figures on the official site. UK Lotto is sold in Australia by The Lottery Office. We are not the operator and we do not sell entries. Lottery play is for adults 18+.
