For this reason alone, Betfair has no reason to ban or close your account when you should win. This is what Betfair first became famous for; peer-to-peer betting. Whilst the Exchange account won't be closed for winning, there is an additional commission rate.

Therefore it is Betfair that set the prices and carry the risk. The odds are generally higher for Singles bets (Exchange) than for the same selections in Sportsbook, but unlike the Exchange, when you place Sportsbook bets you will not pay commission on your winnings.

In the above example, the number is 217.5, meaning you would win an over bet if the score exceeded 217 total points but lose if the total was 217 points or fewer. Over/Under bets are fun ways to have a stake in a game's outcome without having to worry about which team will win.

In sports betting Over 237.5 Points is an example of a total market you might see when betting on Basketball. When betting on the Over market you need the total points of a game to exceed 237.5 for your bet to win.
