Sports Betting FAQ’s

If you are looking to place a sports bet online you have plenty of options. Click on any of our featured betting sites to go straight to their welcome offer or click on the review to read in depth information about each bookie. There are scores of online bookies readily available in the UK, but if you are a sports fan based in the U.S.A. you can’t just gamble online anywhere. Federal law allows each state to decide if online gambling is permitted, and not all online betting sites operate in every state. We’ve got the best sites and the best offers covered, organised by where you are to make your choices easier.

Online sports betting operators offer various bonuses, which could be either welcome promotions for new customers or deposit bonuses, risk free bets or profit boosts for existing bettors. Top online operators like Bet365, William Hill and Betfred also offer free bets and promotional offers when major sporting events like the FIFA World Cup, Tour de France or major golf championships come around. At World Sports Betting we break down the most common types of sports bet bonuses that online betting operators offer.

New Customer Welcome Offers

All the leading online sports betting sites offer welcome bonus offers to new customers. When you register an account with an online bookie you will receive your bonus, either upon your first deposit or when your first bet has settled. These promotional welcome offers usually take the form of one of the bonuses below, or a combination. Often these welcome bonuses will come with play-through or wagering requirements, depending on the type of bet bet and promotion.

Deposit Bonuses

First deposit bonuses offer you either cash or free bets when you make your first deposit. These will be in the shape of a percentage of your first deposit and will have a ceiling on the amount credited. The deposit bonus that William Hill offers when you register is £30 – two £15 free bets when you deposit and bet £10. These deposit bonuses might come with conditions such as wagering or turnover requirements, all of which we detail in our site reviews.

Profit Boosts

With profit boost promotions you say what you see. In simple terms they boost your profits, which could be by 50% or 100%. If you place a bet with profit boost terms at 100%, the online bookie will give you 100% of your winnings as a boost. This is always capped, but the cap could be anywhere from £50 upwards. Say the U.S. Open is kicking off, a top online sportsbook might offer you 100% profit boost bets on every Sloane Stephens or Serena Williams match. She will bag you double profit every time she wins a game, up to the stated cap by the bookie.

Risk Free Bets

You can use a risk free bet to bet on anything you like, with the online sportsbook offering to give you your money back if you lose. These bets might appear as sign up offers or they might be targeted at specific events. For example, Bet365 offers risk free bets on ITV Racing. If your bet wins at 4/1 or more Bet365 will give you a risk free bet for the next race, up to £50. If that bet wins at 4/1 or higher you earn another risk free bet for the next race, and so on.

Extra Sportsbook Bonuses

Bookies often have reward programmes for their customers, either through dedicated VIP schemes or simple ad hoc bonuses. If a major event like Royal Ascot or the Superbowl is on the horizon, your bookmaker will know which sports you like from your betting patterns. So they might send you free bet offers via their dedicated app,  text or email. They might also send you free bet offers for sports you haven’t yet bet on, but might still be interested in. You could follow horse racing form for horses and trainers that regularly sprint race on the flat and place regular bets on those markets, but you might never have placed a bet on the Ashes or Formula 1. Keeping tabs on your chosen marketing preferences from your bookie will keep you in the loop of any such extra online free bets you might be sent.
