The guide
Why bet builder prices differ between bookmakers
Price the same bet builder at two books and you will often get two different numbers. Nothing mysterious is happening. A price is a bookmaker's opinion with a margin attached, and opinions and margins both vary. This page walks through what moves a builder's price, so you can tell a genuine difference from a worse deal dressed up as one.
Margin, multiplied
A decimal price carries a margin: the implied probabilities in a market add up to more than 100%. In a match market the margin might be a few percent. Bet builders multiply prices leg by leg, and the margins multiply with them. A two-leg builder with an ordinary margin in each leg can carry a much larger one combined. This is why two builders that look identical can still cost you differently by the time both legs are priced.
Same match, different prices
Even the plainest market moves between books. The match 1X2 prices we collected on 30 September for Liverpool v Man City put City to win between 2.50 and 2.53, Liverpool to win between 2.53 and 2.55, and the draw between 3.63 and 3.70. Same match, same day, different books. In implied probability, the draw at 3.63 is about 27.5%; at 3.70 it is about 27.0%. Neither number is wrong. They are different opinions at different margins, and on a builder the spread compounds because you multiply it.
Correlation is priced differently
The two legs of our usual shape — a team to win, a player to shoot on target — are correlated, and books treat that correlation differently. Some shade the second leg down when it is tied to the first; others price the legs as if they were independent. Neither is a scam. It is a modelling choice, and it is the biggest reason a combined price for identical legs can differ between books by more than the individual legs ever do.
What to check before you place it
Price each leg at more than one book, not just the combined price.
Multiply the decimals yourself; a builder interface should agree.
Read the implied probability: one divided by the price. If the implied chance is higher than your own read of the game, the price is not worth it, however short the legs look.
Check settlement rules for the shots leg; deflected shots are the classic edge case.
How we price ours
We post one two-leg builder per matchday and quote the best price we could find at the time of posting, with the source named on the page. The record so far is 0-3, -3.0 units at level stakes, every pick settled in public on the record. We print the losses at full size because a price is only worth trusting if the record behind it is honest.
The price is the container
The price is the container; the read behind it is the product. That is what our free builder shows every matchday — legs, combined price, implied probability, and a written reason. Related: what a shots on target bet builder is, and how to check a tipster's record before you follow a pick.
