Before we get into the ranking, we must first of all consider: what is a bookmaker? If you are new to the world of online betting you may not be familiar with all the aspects involved, perhaps not even understand all the odds or how to use free bets. A bookmaker is a professional gaming body that offers you the chance to win money by betting on sports events.
Having originated in the UK, bookmakers have grown in popularity around the world – first as physical shops in the High Street and now as online sites. The principle of betting at these online sites is simple – the probabilities surrounding a sports event are used to determine an odds value, on which you place your stake bet.
