Over the Odds Back to the board

How this works

We don't predict results. We look for prices that are bigger than they ought to be, by comparing every UK bookmaker against the market as a whole.

Every price includes the bookmaker's cut

Think about tossing a coin. Heads and tails are equally likely, so a fair price on each is 2.00 — stake a pound, win a pound.

No bookmaker offers 2.00 on both. They'll offer something like 1.90 and 1.90. That gap is their margin, and it's how they make a living. Across enough bets, it's the reason the house comes out ahead.

The same thing happens on a football match, just harder to see. Add up what the prices imply and you get more than 100% certainty. The extra is the cut.

Home win at 2.2045.5%
Draw at 3.4029.4%
Away win at 3.6027.8%
Total102.7%

Only one of these can happen, so the true total is 100%. The extra 2.7% is the bookmaker's margin.

Take the margin out and you see what they really think

Scale those numbers back down to 100% and you get that bookmaker's honest view of each outcome. In the example above, the home win becomes 44.3% rather than 45.5%.

We do this for every bookmaker pricing that match, which gives us a dozen or more independent opinions with the sales markup removed.

The middle of the market is the best guide we have

Any single firm can be wrong. A dozen firms, all pricing the same match, all with traders watching team news and money coming in, are rarely wrong together.

So we take the middle of their opinions as the true chance, and work out what price that chance deserves. We leave the bookmaker being judged out of its own comparison, or a generous price would drag the average toward itself and hide the very thing we're looking for.

If fewer than a handful of firms have priced a market, we ignore it. A consensus of two isn't a consensus.

The market's true price3.86
One bookmaker is offering4.20
Value+8.8%

That firm is slower, or more generous, than the rest of the market. That's the bet.

What value actually means

A bet listed at 5% value doesn't win 5% more often. It means that if you could play that same bet a thousand times, you'd expect to end up about 5% ahead of where you started.

You can't play it a thousand times. You get one go, and it either wins or it doesn't. Which is why this only makes sense across hundreds of bets, and why anyone judging it over a weekend is judging luck.

Losing weeks are normal. Losing months happen. If that sounds like a poor pitch, it's an honest one, and it's the same maths the bookmakers rely on from the other side.

Why the prices move

We collect prices twice a day. Bookmakers change theirs constantly, so by the time you look, a price may have shortened or gone entirely. Always check the price before betting — if it's moved, the value may have gone with it.

We don't leave dead bets on the board. Every sweep rebuilds the list from scratch, so anything that no longer qualifies simply disappears.

Why we publish our record

Anyone can claim an edge. Almost nobody shows their working.

Every selection we list is recorded, settled from the result, and counted. Not the good ones. All of them. The Record page shows the strike rate, the return at level stakes, and how often our price beat the market's closing price.

That last figure matters most. If we consistently list prices bigger than the market settles on by the start, that's a real edge showing up long before profit does. Above 55% is a genuine signal. Below 50% means we're finding noise, and we'd rather you could see that for yourself.

What this isn't. These aren't tips or predictions, and there's no guarantee attached to any of them. We have no idea who wins a given match. We only know which prices look generous compared with the rest of the market.

Bet only what you can afford to lose, and stop if it stops being enjoyable.

A note on bookmaker accounts

Bookmakers don't much like customers who consistently take the best price. Accounts get stake-limited or closed, sometimes within weeks. Spreading your bets across several firms and keeping stakes to sensible round numbers helps, but it happens to most people eventually. Worth knowing before you start.
