Thunderball draws 5 main numbers from 39 and 1 Thunderball from 14. Below is every prize tier with its exact odds, the combinatorics behind the jackpot, and interactive tools to put those numbers in perspective.
Thunderball in plain English
A Thunderball line picks 5 main numbers from 39 and 1 Thunderball from 14. Match everything for the jackpot — there are several smaller tiers below it too.
Thunderball's big draw is that every prize is fixed — the top prize is always £500,000, no matter how many people win it, and you can win the smallest prize by matching just the Thunderball. Draws are four nights a week (Tue, Wed, Fri, Sat).
That single number is where every odds figure on this page comes from: you choose 5 main numbers from 39, then 1 from 14, giving 8,060,598 equally-likely outcomes. Exactly one of them is the jackpot line — which is why the jackpot odds are 1 in 8,060,598.

What's a ticket really worth?
Thunderball has fixed non-jackpot prizes, so we can compute the exact average return of the smaller prizes. Enter a jackpot to see the full picture. (Ignores tax & shared jackpots — read the note.)
Expected value is what an average ticket returns over the very long run — it is not a prediction and never exceeds the ticket price across a fair lottery. Real returns are lower after tax and any shared jackpots.

Thunderball myths, busted
Every Thunderball draw is independent. A number that hasn't appeared in months is exactly as likely as any other — the balls have no memory.
Random picks and hand-chosen lines have identical odds. Quick picks only win more in total because more people use them.
A line like 1-2-3-4-5 is exactly as likely as any other. The only reason to skip popular patterns is to avoid sharing a prize if they come up.
