Scratchcard odds: what the printed odds really mean

Scratchcards print a line such as "overall odds 1 in 3.49". It sounds generous, and in one sense it is: roughly one card in three and a half wins something. What the line does not say is what that something is worth, or how long the odds of the top prize are. This page unpacks the number.

What the printed scratchcard odds mean

The odds printed on a scratchcard are its overall odds: the chance that one card wins any prize at all. The £5 Deal or No Deal card launched in February 2026 prints 1 in 3.49, which means that across every card printed for that game, about 28.7% win something and 71.3% win nothing. A second £5 card from the same year, Beat The Chasers, was reported at 1 in 3.52, although that figure reached us through a search snippet rather than the operator's own page. Both sit close to the "1 in 3.5" that people often quote.

The key word is "any". The overall odds count the smallest prize just as they count the largest. On many cards the lowest prize is simply the price of the card, so a "win" often means getting your stake back and nothing more. We could not read the operator's full list of retail cards and their prize tables, so we cannot say how often that is true across the range; the rules printed for each game give the answer for that game. The practical reading is this: 1 in 3.49 tells you how often a card is not a total loss, not how often it makes a profit.

The odds also describe the whole print run of a game, not the cards in one shop. A particular roll of cards can be luckier or unluckier than the average, and nothing on the card lets you tell which.

Top-prize odds against overall odds

The top prize is a different calculation. A game is printed with a fixed number of top prizes: the £5 card above has 4 top prizes of £1.5 million, the second £5 card was reported with 5, and a £10 card announced in August 2026 has 4 of £4 million, which the operator said doubled the previous highest scratchcard top prize of £2 million. The chance of any one card holding a top prize is the number of top prizes divided by the number of cards printed.

Top-prize odds = 1 in cards printed ÷ number of top prizes

The print runs of these games are not in the sources we checked, so we cannot give their top-prize odds, and we would rather print nothing than a guess. To show the scale, take a made-up game: if 10,000,000 cards were printed with 4 top prizes, each card would have a 1 in 2,500,000 chance of one. In that imaginary game, the overall odds of 1 in 3.49 and the top-prize odds would differ by a factor of about 716,332. That gap, not the headline line on the back, is what separates a small win from a very large one. For the £10 card, the operator also said retailers earn 60p on each one sold, 6% of the price.

The National Lottery Instant Win range

Online Instant Win Games work the same way on a screen. On 2 October 2026, the National Lottery listed 83 of them, with overall odds from 1 in 2.28 to 1 in 2.98; the middle game sat at 1 in 2.69. Converted to a percentage, that is a chance of a prize on each play of between 33.6% and 43.9%, with 37.2% in the middle. So the online games, on these figures, pay out a prize of some kind more often than the two retail cards above.

As with paper cards, those figures count every prize, and the listing does not say what share of the money staked comes back. We could not confirm the price of each online game, so we do not quote prices here.

Buying several cards: how the odds are calculated

Buying more cards raises the chance of winning something, but more slowly than intuition suggests. The easy way to work it out is to find the chance that every card loses and take that away from one. With overall odds of 1 in 3.49, each card loses with probability 0.7135, so:

P(at least one prize from n cards) = 1 − (1 − 1/3.49)n

This treats each card as independent, which is very close to true when a game has millions of cards in circulation. The table applies it to three sets of odds: the most generous online game, the middle online game and the £5 retail card.

594.4%90.2%81.5%1.43
1099.7%99.0%96.6%2.87

Even ten cards at 1 in 3.49 leave a 3.4% chance that none wins anything, about 1 in 29. And a prize from several cards is not the same as coming out ahead: ten £5 cards cost £50, and on average only 2.9 of them win, and some of those wins may be no more than the smallest prize. Buying more cards never changes the odds on any single card; it only buys more tries at the same price.

Do scratchcards pay back more than the draws?

This is the question people most want answered, and the honest answer is that the published figures do not settle it. For a draw game with fixed prizes you can multiply each prize by its chance and add them up, which is how we found that a £1 Thunderball line pays back 52.88p on average. For a scratchcard you would need the full prize table and the print run, and we could not verify either from the operator's own pages. The Gambling Commission's breakdown covers all National Lottery sales together, 55p in the pound to prizes in April 2024 to March 2025, and gives no figure for each game. Until a per-game figure is published, anyone telling you scratchcards are better or worse value than the draws is guessing.

Scratchcards against the UK draws

On the one measure the figures do allow, the chance of winning anything, instant games win often and draw games rarely. The table puts them side by side.

Chance of winning any prize from one card, play or line
GameAny prize, 1 inAs a percentage
Online Instant Win (range)2.28 to 2.9833.6% to 43.9%
£5 scratchcard (2026 example)3.4928.7%
Lotto (two rounds a draw)4.920.4%
Thunderball (exact)12.388.1%
Set For Life (exact)12.418.1%
EuroMillions137.7%

A card at 1 in 3.49 wins something about 3.5 times as often as a Thunderball line. That frequency is exactly what makes instant games feel rewarding, and on its own it says nothing about value for money. For the draw games, where every tier can be counted, the UK lottery odds page compares the jackpots and the lottery odds calculator works out your chance for any number of lines.

Instant games are quick, and a result a few seconds after paying makes it easy to buy the next card straight away. If that rhythm is getting hard to stop, the responsible gambling page lists free support you can reach today.

Scratchcard odds: questions people ask

What does "1 in 3.5" on a scratchcard mean?

It is the overall chance that a card wins any prize at all, the smallest prize included. At 1 in 3.49, the figure on a £5 card launched in 2026, about 28.7% of all the cards printed for that game win something and 71.3% win nothing.

Are the printed odds the chance of winning the top prize?

No. The printed overall odds cover every prize on the card. The chance of the top prize is far longer, and it depends on how many cards are printed and how many top prizes there are in the game.

If I buy 4 scratchcards at 1 in 3.5, will one of them win?

Not necessarily. With overall odds of 1 in 3.49, the chance that at least one of four cards wins something is 74.1%, so roughly one time in four, all four lose.

Does winning a prize mean I made money?

Not always. The overall odds count every prize, and on many cards the lowest prize is no more than the price of the card, so a win can simply mean getting your stake back. The prize table in the rules of each game shows what each prize is worth.

What are the odds on National Lottery Instant Win games?

On 2 October 2026, the 83 online Instant Win Games listed by the National Lottery had overall odds between 1 in 2.28 and 1 in 2.98, with a middle value of 1 in 2.69. That is a chance of 33.6% to 43.9% of a prize per play.

What is the biggest scratchcard prize in the UK?

In August 2026 the operator announced a £10 card with 4 top prizes of £4 million, which it said doubled the previous highest scratchcard top prize of £2 million. The odds of those top prizes were not given in the announcement.

Do dearer scratchcards have better odds?

Not in any fixed way that our sources confirm. The two £5 cards we have figures for print 1 in 3.49 and 1 in 3.52, and the online games range from 1 in 2.28 to 1 in 2.98. Dearer cards tend to carry bigger top prizes; check the printed odds on each one.

Do scratchcards pay back more than lottery draws?

We cannot say from published figures. The Gambling Commission gives one breakdown for all National Lottery sales, 55p in the pound to prizes in April 2024 to March 2025, and no figure for each game. Thunderball, by contrast, pays 52.882% of sales in prizes.

Is a scratchcard more likely to win than a lottery ticket?

For some prize, yes. A card at 1 in 3.49 wins something about 3.5 times as often as a Thunderball line, whose exact any-prize chance is 1 in 12.38. For a top prize, the comparison depends on the print run, which is not on the card.
