How Thunderball numbers work

The Thunderball is selected separately from 1–14. It may match a main number.

This page is for Thunderball (UK). Main numbers are distinct and displayed in ascending order. Extra numbers are selected independently from their own pool; a value may also appear among the main numbers.

The odds shown on this page

Match 5 main numbers and the Thunderball. Under a fair draw, the displayed chance for one complete line in one round is 1 in 8,060,598. This is the specified top-match category, not the chance of winning any prize.

C(39, 5) × 14 = 8,060,598

C(n, k) counts unordered selections of k distinct values from n. The science of chance explains why past results and visually balanced patterns do not improve a particular line’s chance.

Keeping the game in perspective

If the next draw feels difficult to leave alone, read about the urge to win losses back. For a conversation rather than more numbers, see support in United Kingdom or choose where you actually live.
