The UK National Lottery has been part of British life since November 1994, and its flagship game — simply called Lotto — remains one of the most widely played games of chance in the country. Millions of tickets are sold each week, yet many players have only a vague idea of how the draw is structured, how the prize tiers work, or what happens to the money they spend. This guide walks through the whole process from ticket purchase to prize payout.
Choosing your numbers
A Lotto line consists of six numbers chosen from 1 to 59. Players can select their own numbers or opt for a Lucky Dip, which generates a random selection at the point of sale. Each line costs a fixed price, and tickets can be bought in person at licensed retailers — supermarkets, newsagents, petrol stations — or through the official National Lottery website and app, where you must be 18 or over and registered with a verified account.
Many players stick with the same numbers every week. There is no mathematical advantage in doing so, but there is no disadvantage either; every combination has an identical chance in every draw. Where it can matter is psychologically — some players feel unable to skip a week in case “their” numbers come up, which is a habit worth being aware of.
You can also buy tickets in advance for multiple draws, or set up a subscription online so that your lines are entered automatically. Subscriptions remove the risk of forgetting to play, but they also remove the pause in which you might decide not to.
The draw itself
Lotto draws take place on Wednesday and Saturday evenings. A mechanical draw machine, loaded with a certified set of 59 numbered balls, releases six main balls followed by one Bonus Ball. Each draw is overseen by an independent adjudicator, and the results are published on the official site within minutes.
The Bonus Ball is relevant only to players who have matched five of the six main numbers. Matching five main numbers plus the Bonus Ball earns a considerably larger prize than matching five alone. It is not used at any other tier and is not a seventh number to pick.
Prize tiers
Prizes are awarded for matching two or more main numbers. The structure below is indicative; the operator publishes exact figures and they can change.
| Match | Prize type | Approximate odds (per line) |
| 6 main numbers | Jackpot (shared if multiple winners) | 1 in 45,057,474 |
| 5 main + Bonus Ball | Fixed prize (around £1 million) | 1 in 7,509,579 |
| 5 main numbers | Fixed prize (around £1,750) | 1 in 144,415 |
| 4 main numbers | Fixed prize (around £140) | 1 in 2,180 |
| 3 main numbers | Fixed prize (£30) | 1 in 97 |
| 2 main numbers | Free Lucky Dip | 1 in 10.3 |
The overall chance of winning any prize on a single line, including the free Lucky Dip, is around 1 in 9.3. The chance of winning cash is roughly 1 in 54.
Since the 2018 rule changes, most tiers pay fixed amounts. The jackpot is the exception: it is a pool that is shared equally among all jackpot winners in that draw.
Rollovers and “must be won” draws
If no ticket matches all six numbers, the jackpot rolls over and is added to the next draw’s jackpot. This is what produces the large advertised prizes that attract extra ticket sales.
Rollovers are not unlimited. Once the jackpot has rolled over five times, the next draw becomes a “Must Be Won” draw. If nobody matches six numbers in that draw, the jackpot is shared among all players who win a cash prize in the lower tiers — a “rolldown”. Rolldown draws can produce unusually large payouts for matching three, four or five numbers, and they generate a lot of interest for exactly that reason.
Where the money goes
Every pound spent on a Lotto ticket is divided in a way that is set out in the operator’s licence and published annually. The broad proportions are:
| Destination | Approximate share |
| Prizes to players | Around 50–55% |
| Good causes | Around 20–25% |
| Lottery Duty (to the Treasury) | 12% |
| Retailer commission | Around 4–5% |
| Operator costs and profit | The remainder |
The “good causes” share is distributed by twelve bodies including Arts Council England, Sport England, the National Lottery Heritage Fund and the National Lottery Community Fund. Since 1994 the lottery has raised tens of billions of pounds for projects ranging from Olympic athlete funding to village hall refurbishments.
The operator since 1 February 2024 has been Allwyn, which took over from Camelot after 28 years.
Checking and claiming
Results can be checked on the official website, in the app, at any retailer, or through the site’s results page. Prizes must be claimed within 180 days of the draw date; small prizes can be paid at retailers and larger prizes require a claim through the operator. A separate post in this series covers the claiming process in detail.
