What Are the Odds of Winning the Lottery?
This is an independent, informational guide for UK readers and is not affiliated with the organisations mentioned. It is provided for general information only.
The odds of winning the lottery are very long and depend on the game: roughly 1 in 45 million for the Lotto jackpot and about 1 in 139 million for EuroMillions. Winning some kind of prize is far more likely — around 1 in 9 to 1 in 13 — but those wins are usually small, often just a few pounds or a free line.
Jackpot odds for each UK game
The odds depend heavily on the game. For the National Lottery's Lotto, the chance of matching all six main numbers is about 1 in 45,057,474. EuroMillions has far longer odds because of its two Lucky Stars: roughly 1 in 139,838,160 for the jackpot.
Among the main draw games, Thunderball has the shortest jackpot odds at around 1 in 8,060,598, while Set for Life sits at about 1 in 15,339,390. Shorter odds come with smaller top prizes.
Odds of winning any prize
Winning something is far more likely than the jackpot. The overall odds of any prize are roughly 1 in 9 for Lotto and around 1 in 13 for EuroMillions and Thunderball, with Set for Life similar.
The catch is that most of those wins are small — often just a few pounds or a free line — rather than life-changing sums.
Putting the odds in perspective
Every line you buy is independent and faces the same long odds, so buying more lines increases your chance only in proportion — and it stays very small. No system, lucky number or app changes the underlying maths.
The sensible way to treat the lottery is as a flutter for fun, with a budget you are comfortable losing, rather than a financial plan.
Why the odds are so long
The maths comes down to combinations. Choosing six numbers from 59, as in Lotto, produces tens of millions of possible combinations, and only one wins the jackpot.
Adding extra numbers makes it harder still, which is why EuroMillions, with its two Lucky Stars on top of five main numbers, has the longest odds of all the main UK games.
Which UK lottery has the best jackpot odds?
Among the main draw games, Thunderball has the shortest jackpot odds at about 1 in 8 million, though its top prize is capped at £500,000.
Does buying more tickets improve my odds?
Only in proportion — two lines double a tiny chance to a still-tiny chance. It does not meaningfully change the outcome.
Can you improve your chances of winning?
No method or number-picking system changes the odds; the only way to have more chances is to buy more lines, which still leaves the odds very long.
Why are EuroMillions odds longer than Lotto?
Because EuroMillions asks you to match five main numbers plus two Lucky Stars, creating far more possible combinations than Lotto.
