What Do You Win for 2 Numbers on Thunderball?
Here’s the answer most players don’t expect: two main numbers alone win nothing on Thunderball. But two main numbers plus the Thunderball win a fixed £10. Whether your fifth ball came up decides everything at this level — and it’s the single most common point of confusion in the game.
The full answer
Thunderball draws five main numbers from 39 and one Thunderball from 14. The prize table requires either three or more main numbers, or the Thunderball itself, before anything pays. So: two mains with the Thunderball is £10; two mains without it is a losing ticket, however close it feels. One main plus the Thunderball pays £5, and the Thunderball entirely alone pays £3 — meaning a ticket with fewer matched numbers can beat one with more, if the Thunderball is among them.
Why the game works this way
Thunderball’s identity is its fixed prizes and its bottom-heavy ladder, and the Thunderball itself is the key that unlocks the lower tiers. In our simulation of 100 million tickets, over seven million of the eight million winning lines involved the Thunderball — it, not the main numbers, is where most of the game’s prizes actually live.
The prizes around this level
Three main numbers pay £10 with or without help; three plus the Thunderball pay £20; the ladder climbs to £500,000 for the full five-plus-Thunderball, always fixed, never shared, never rolled over. Every line costs £1 and plays a single draw — Thunderball was untouched by the June 2026 changes to Lotto and HotPicks.
Checking near-miss tickets
Because the Thunderball changes everything, always check the last ball before binning a “two number” ticket — £10 wins are claimed automatically online, or over any store counter for retail tickets.
Frequently asked questions

The Thunderball — two mains plus it pays £10, the same as three mains without it.
Did the June 2026 changes affect Thunderball?
No — Thunderball kept its £1 single-draw format and its full fixed prize table.
