The Editorial Team writes in plain English, using labelled examples to explain how odds, returns and settlement can work. Guides distinguish general explanations from the specific terms that may apply to a bet or promotion; readers should check the relevant operator’s rules and conditions.
What do betting odds mean?
Odds show the price of a bet and can be used to calculate a potential return. Fractional and decimal odds express the same kind of price in different formats.
What does it mean when a bet is settled?
Settlement is the process of determining the outcome of a bet under the relevant market rules. Depending on those rules, a bet may be settled as a win, a loss or a void, among other outcomes.
Is a free bet stake returned with winnings?
It depends on the promotion terms. If the terms say the stake is not returned, it is excluded from the return on a winning free bet.
Why might an in-play market be suspended?
A market may be suspended while a bookmaker assesses an event or updates prices, for example after a significant incident. The circumstances and duration can vary.
What is cash out?
Cash out is an offer to settle a bet before its usual conclusion for a stated amount. The offer can change or become unavailable, and accepting it may return less than the original stake.
