How to Judge the Odds
Convert each price to an implied probability and add them up across a market. For decimal odds, the probability is 1 divided by the odds; for fractional odds such as 10/11, it is 11 divided by 21. On a two-way market a total of 104-106% is normal for major events.
| Market | Odds A | Odds B | Implied total | Margin |
|---|---|---|---|---|
| Example: tennis match | 10/11 (1.91) | 10/11 (1.91) | 104.7% | about 4.7% |
| Example: niche esports | 4/5 (1.80) | 17/20 (1.85) | 109.6% | about 9.6% |

Sports Bonuses
Since January 2026, UK-licensed operators may not tie casino and sports offers together in one bonus. Offshore sites are not bound by that rule and often attach minimum-odds and rollover terms. Read the sports terms separately.
