UK Lotto Bonus Ball
The bonus ball is a seventh ball drawn after the six main numbers in each UK Lotto draw. In the UK game it boosts certain prize tiers — and when you bet, you can treat it as its own market. Here is how it works.
How the bonus ball works
After the six main numbers are drawn, a seventh ball — the bonus ball — is drawn from the same 1 to 59 pool. In the official UK game it lifts the prize for players who matched five main numbers plus the bonus. When you bet on UK Lotto, you can back the bonus ball as its own fixed-odds market, separate from the main numbers, with the payout shown before you confirm. With the new two-round format, each round has its own bonus ball. See the UK Lotto guide for the full picture, or odds and payouts for pricing.
Frequently asked questions
Can I bet on just the bonus ball?
Yes. The bonus ball is its own market, drawn from the 1 to 59 pool after the six main numbers, and you can back it on its own at fixed odds.
Does each round have a bonus ball?
Yes. Since the June 2026 two-round change, both Round 1 and Round 2 draw their own bonus ball.
