We Simulated 100 Million Thunderball Tickets

We ran 100 million £1 Thunderball lines through a computer simulation using the game’s exact odds and its nine fixed prizes. The results: 8,078,293 winning tickets, ten £500,000 jackpots, and £51.7 million paid back from £100 million spent — a 51.7% return, quietly one of the most generous in the National Lottery family.

How the simulation worked

Every line was checked against a simulated draw of five main numbers from 39 plus a Thunderball from 14, with the nine fixed tiers from £3 to £500,000 applied exactly as published. Because Thunderball prizes never share and never roll over, the simulation mirrors the real game almost perfectly.

What the 100 million tickets won

Match Prize Winning tickets
5 + Thunderball £500,000 10
5 £5,000 164
4 + Thunderball £250 2,132
4 £100 27,254
3 + Thunderball £20 69,610
3 £10 904,547
2 + Thunderball £10 743,574
1 + Thunderball £5 2,878,921
Thunderball only £3 3,452,081

What that means per ticket

Roughly one line in every 12.4 won something — in line with the game’s published overall odds of about 1 in 13 — and the average return worked out at almost 52p per £1, comfortably ahead of Lotto’s fixed-tier figure. The Thunderball itself did most of the work: over 7 million of the 8.1 million wins involved it, including 3.45 million £3 saves from matching nothing else at all.

Ten jackpots — and a lesson about luck

The maths expected around twelve £500,000 winners in 100 million tickets; our run produced ten. Even at this enormous scale, chance is lumpy — which is exactly why a hot streak or a cold streak in real draws means nothing. Every ticket faced identical odds of 1 in 8,060,598 for the top prize.
