Wondering if matching just one number and the Bonus Ball in Lotto is enough to land you a win? You’re not alone. With thousands of players every week, it’s one of the most common questions asked after a draw.
Before you dismiss a ticket or let your excitement build, it helps to understand how the Lotto prize structure works in the UK and where the Bonus Ball actually matters. Read on and we’ll clear up the myths, explain how the Bonus Ball is used, and spell out what to expect if your ticket shows a 1 + Bonus Ball match.
How Does The Bonus Ball Work In UK Lotto?
After the six main numbers are drawn, a seventh ball is pulled from the remaining numbers—this is the Bonus Ball. The draw starts from a single pool of 59 balls, so the Bonus Ball cannot duplicate any of the six main numbers that were already selected.
Crucially, the Bonus Ball only affects one prize tier: it can increase the payout for players who have matched exactly five of the six main numbers. It does not create extra winning categories and it does not convert otherwise non-winning combinations into prizes. That’s why understanding which tiers use the Bonus Ball makes it much clearer whether a given ticket qualifies for anything.
Now that you know where the Bonus Ball fits into the structure, the next section explains exactly what happens when you have only one main number plus the Bonus Ball on your ticket.
Does One Main Number And The Bonus Ball Win Anything?
If your ticket has one main number and the Bonus Ball, that combination does not meet the minimum requirement for a prize. The smallest paid prize in Lotto is for matching two main numbers; the Bonus Ball only comes into play for the specific case of matching five main numbers plus the Bonus Ball.
In short, a 1 + Bonus Ball match is not a recognised winning combination in the prize table. That means it won’t produce a payout, even though it might feel close. Check the official prize table if you want to see the exact thresholds and payouts for each tier.
With that settled, here’s a closer look at the prize tier that actually uses the Bonus Ball.
Prize Tiers That Use The Bonus Ball
Only one prize tier makes use of the Bonus Ball: matching five of the six main numbers and also matching the Bonus Ball. This tier sits immediately below the jackpot, which requires all six main numbers.
All other tiers are determined solely by how many main numbers are matched:
- matching two main numbers is the smallest winning category,
- three or four matched main numbers pay higher fixed or variable amounts,
- five main numbers alone give a larger prize, and
- matching all six wins the jackpot.
Because the Bonus Ball applies only to the five-main-numbers tier, it acts as a specific top-up for that group rather than a general booster for low-tier matches.
If you’re curious about how common or rare a 1 + Bonus Ball outcome is, the next section puts that into context.
How Likely Is Matching One Number And The Bonus Ball?
Official odds are published for the recognised prize tiers, but there aren’t separate published odds for a 1 + Bonus Ball combination since it isn’t a winning category. For context, the odds of matching two main numbers—the lowest paid tier—are around 1 in 10.3.
Although exact frequencies of non-paying combinations aren’t usually listed, you can expect many tickets to include single-number matches or other near-misses simply because of the range of numbers players choose. Those outcomes are part of the statistical spread of the draw and don’t translate into prizes unless they meet a paid tier.
Next, if you believe you do have a winning combination that involves the Bonus Ball, here’s how the checking and claiming process generally works in practice.
How To Check And Claim A Bonus Ball Win?
When a ticket appears to match a five-main-numbers-plus-Bonus-Ball combination, the practical steps to verify and claim are straightforward but worth handling carefully. Start by comparing your ticket with the official published draw results and the prize table to confirm the exact tier matched. For modest prizes, verification can usually be done at a point of sale; larger amounts require contacting the official claims service and following their verification procedures.
Keep the ticket safe, note the draw date, and be aware of any time limits or documentation the claims process requires. If you have doubts about whether a specific match qualifies, an official prize table or customer service channel will confirm the outcome and explain the necessary paperwork.
If you’re checking a large number of tickets, it’s sensible to use an official results page or a reputable app to avoid mistakes. The important point is that only the five-main-numbers-plus-Bonus-Ball combination triggers a Bonus Ball prize—everything else is assessed on the number of main numbers matched.
This wraps up the key facts: the Bonus Ball has a narrow but specific role, and a ticket showing one main number plus the Bonus Ball does not qualify for a prize. If you’re reviewing tickets after a draw, focus on how many main numbers match and consult the official prize table to see where your entry sits.
