What are the odds of winning the Thunderball jackpot?

There are 8,060,598 possible tickets (5 numbers from 1–39, plus 1 Thunderball from 1–14), so a single line has a 1 in 8,060,598 chance of matching everything. Every figure in the table on this page is that total divided by the number of ways to hit each tier.

Does using a generator improve my chances?

No. Every ticket in a fair draw has identical probability and nothing about how you choose the numbers changes that. A random pick only reduces the chance of sharing a jackpot, because human choices cluster on dates and patterns.

Are these numbers really random?

They come from crypto.getRandomValues() in your browser, the same source used for security-sensitive work. Numbers are drawn without replacement, so a line never repeats a number, exactly like a real draw.

When is Thunderball drawn?

Tuesday, wednesday, friday and saturday evenings. Always check your operator for cut-off times, which are earlier than the draw itself.

Thunderball Number Generator

This generator draws 5 numbers from 1–39, plus 1 Thunderball from 1–14, the exact matrix Thunderball uses. Numbers come from your browser’s crypto.getRandomValues() and are drawn without replacement, so a line never repeats a number. Nothing you generate is sent anywhere.

Thunderball pays fixed cash prizes rather than a pari-mutuel share, so the top prize is £500,000 whether one ticket wins it or ten do. The jackpot never rolls over, which is why it stays small relative to the US games.

Every Thunderball Prize Tier

There are 8,060,598 distinct tickets: C(39,5) × C(14,1). Each row below is that total divided by the number of ways to hit the tier, so these are the game’s actual odds rather than a marketing summary.

Match	Winning combinations	Odds
Match 5 + Thunderball	1	1 in 8,060,598
Match 5	13	1 in 620,046
Match 4 + Thunderball	170	1 in 47,415
Match 4	2,210	1 in 3,647
Match 3 + Thunderball	5,610	1 in 1,437
Match 3	72,930	1 in 110.5
Match 2 + Thunderball	59,840	1 in 134.7
Match 1 + Thunderball	231,880	1 in 34.8
Match 0 + Thunderball	278,256	1 in 29.0

Adding the nine tiers together gives about 1 in 12.4 for a single line. Operators and summary sites usually quote “about 1 in 13”; the per-tier figures above are straight arithmetic from the matrix and are not in doubt, but we cannot reconcile the rounded overall, so treat it as approximate.

Can a Generator Improve Your Odds?

No, and it is worth being plain about that. Every ticket in a fair draw carries the same probability, and no method of choosing numbers changes it. What a random pick does change is who you share with if you win.

Human number choices cluster heavily. Dates crowd everything into 1–31, patterns drawn across the slip repeat, and previous winning lines get reused. Because jackpots are divided among winning tickets, a popular combination pays less per winner. Picking outside those habits does not make a win likelier, only less crowded.

Odds computed from the published Thunderball matrix using the hypergeometric distribution. Prize structures and pool sizes do change: always confirm the current rules with your operator before buying.
