How to Check the Odds on an Instant Win Competition

Instant win competition odds aren't printed on the front page, but you can work them out with a bit of sums and a careful read of the prize list. I've spent over 20 years around betting and prizes, and the habit that serves punters best is the same everywhere: know what you're paying for before you pay. This guide uses three numbers: the ticket cap, the tickets sold and the number of instant prizes. It won't tell you whether you'll win (nothing can), but it will show you what the competition is really offering.

New to the format? Our instant wins explained guide covers the basics first.

What "odds" means in a capped competition

In a bookmaker's market, odds come from a price. In a capped competition, they come from a count. There's a fixed maximum number of tickets (the cap) and a fixed number of prizes. Your chance is roughly your tickets divided by all the tickets in play.

Two things make that slightly slippery. The cap is the most tickets that can be sold, not the number that have been sold. And an instant win competition usually has two layers: the instant prizes you might find straight away, and an end prize drawn afterwards. Each has its own odds, so check them separately.

Ticket cap vs tickets sold

The cap sets the floor for your odds. If a competition has a cap of 15,000 and sells out, each ticket is one of 15,000. If it sells fewer, each ticket is one of fewer, so the maths improves for everyone holding one.

That's the catch. You can't know in advance how many will sell. Look at the live ticket counter if there is one, and treat the cap as the worst case, not a forecast. A competition that has sold a small fraction of its cap may stay that way, or may fill up fast. It's not an exact science.

Our first Racing instants competition is a good example. The ticket cap was 15,000, and it sold 1,793 tickets. Same prizes, very different odds from a sell-out. 

How instant prizes change the maths

Instant prizes add a second question: how many of the tickets carry a prize at all? Count every prize on the list, add up the quantities, and compare that to the cap.

Then look at the mix, because the headline prize and the typical prize are very different animals. In the Racing instants prize list, the top tier was a handful of single prizes, such as a pair of Cheltenham Festival 2027 Platinum Suite tickets worth £1,200, a 12 month OLBG Racing Club membership and a £250 Instant Cash prize. The bulk of the list was site credit, in £1, £2.50 and £5 amounts.

Then there's what happens to prizes nobody wins. In our case, instant prizes that aren't won are rolled over to future competitions. Check the rules wherever you play, as they tell you whether unclaimed prizes simply disappear.

A worked example

Here's the Racing instants competition, which had a £500 end prize. The instant prize list had 1,239 prizes in total

• Cheltenham Festival 2027 Platinum Suite pair (worth £1,200) – 0 of 1 won
• Owners' Club pair, Newbury, 24th October – 1 of 1 won
• 12 Month OLBG Racing Club membership – 0 of 1 won
• £250 Instant Cash – 0 of 1 won
• Premier Admission pair, Newbury, 24th October – 1 of 4 won
• Micro Share in Pass the Buck – 0 of 4 won
• £100 Instant Cash – 0 of 2 won
• £50 Instant Cash – 0 of 5 won
• £25 Instant Cash – 1 of 10 won
• £10 Instant Cash – 1 of 15 won
• £5 Site Credit – 10 of 100 won
• £2.50 Site Credit – 47 of 380 won
• £1 Site Credit – 102 of 715 won

Now the sums:

• At the full cap: 1,239 instant prizes across 15,000 tickets is roughly 8.3%, or about 1 in 12, if every prize sits on a different ticket. [CHECK: confirm how instant prizes are allocated to tickets]
• At the tickets actually sold: 163 instant prizes were won from 1,793 tickets, about 9%.
• The headline prizes: the £250 cash prize, the Cheltenham pair and the membership were 3 prizes in a 15,000 cap. The Owners' Club pair was won, but the other three weren't.
• The mix: 1,195 of the 1,239 prizes (about 96%) were site credit. Fine if you'll use it, but a different proposition from cash or tickets.
• The end prize: with 1,793 tickets sold, the £500 end prize was roughly 1 in 1,793 per ticket. Richard A won it.

What to look for before entering

1. The cap and the counter. Know the maximum number of tickets and how many have sold.
2. The full prize list. Add up the quantities, then split cash and tickets from site credit.
3. Prizes won so far. If the list shows won and remaining counts, you can see how much of the pool is still live.
4. Unclaimed prize rules. Do they roll over, get drawn another way, or vanish?
5. The end prize. Check its value and how it's drawn, separately from the instants.
6. The ticket price against the realistic prize. Most instant prizes will be the smaller ones, so judge the offer on that, not on the top prize.
7. Fairness signals. Our guide on how to spot a fair instant win competition goes through them. If you're also weighing up formats, see instant wins vs main draws.

Foolproof it isn't, and most entrants won't win a prize. Only spend what you're comfortable losing.
