In the US, sportsbooks online are legal in a growing number of states. This expansion began with the Supreme Court overturning a federal ban in 2018. Licensed operators can now open sportsbooks online and offer betting on professional and collegiate games.
The best sportsbook websites make wagering easy. They load quickly and reliably, feature a clean layout with an accessible betslip, and provide extra features like detailed pre-game statistics and same game parlay builders. Some sites also offer free bets and a large selection of recurring promotions, including odds boosts and money back specials.
Other popular bets include totals, which are based on the expected number of points, goals or runs scored in a particular game. The best sportsbooks will offer a range of different totals, including team and player totals, as well as half and quarter lines. Some also offer alternative totals, such as run line or puck line betting for hockey games.
Aside from a great selection of bets, the top sportsbooks also offer fast payment speeds and responsive customer support. Some even offer a mobile app for easier access and convenience. Many of these sites also accept cryptocurrencies, such as bitcoin, for added flexibility.
It is important to note that profits from sports betting and other forms of gambling are taxable in the United States. This is why it is a good idea to track your winnings and consult with a tax advisor if necessary. Some sportsbooks will provide you with a 1099-G form that documents your winnings.
