Besides offering competitive odds, a sportsbook should also have a variety of sports markets, friendly customer service, and a secure site. You should also have access to banking options, prepaid cars, and other features to make your online sports betting experience as comfortable as possible.

Several legal online sports betting sites offer bonuses to attract sports bettors. These bonuses may include free bets, risk-free bet offers, and first-deposit match bonuses. Each bonus offer is different. The best sportsbook bonus codes can get you deals worth hundreds of dollars.

Among the most popular US sportsbooks are DraftKings and FanDuel. These two brands offer innovative features and competitive odds. They’re available in more than twenty states and are expected to expand in the near future.

DraftKings was the first legal online sportsbook in the United States. The company has a user-friendly interface, wide selection of sports markets, and innovative features like a risk-free bet and same-game parlays.

The risk-free bet offer is a popular sportsbook promo. This means that you get to keep your winnings even if your original bet loses. However, you’ll need to make a substantial deposit before you can convert your winnings into real money.

Some sportsbooks offer free bet credits instead of a lump sum. This is an excellent way to make smaller wagers while still having more freedom. The only catch is that you won’t be able to withdraw your bonus funds.

Another common sportsbook promotion is the odds boost. This is a way to lower the bookmaker’s juice and increase your chances of winning.
