Since 2018, states across the United States have been legalizing sports betting. Wagering in the US is now much more than just sitting at a sportsbook on the Vegas strip.

Over half of the states in the US have legalized sports betting apps. However, the laws and number of sportsbooks available will vary.

Our online sportsbook reviews will provide loads of information, including features, betting options, banking methods, customer support methods, rewards, and bonuses. Most importantly, if a promo code is needed, we have it. Get free bets as soon as you register!

We rate each online betting app, giving you an idea of how each operator stacks up against the competition.

For people in many states, there’s no need to visit a physical casino in order to play your favorite slots or table games for real money.

Just like sportsbooks, US online casinos have been launching around the country in states that have legalized the industry. But casino apps aren’t in quite as many states as sportsbooks.

Check your state’s gambling page to see where you can play Roulette, Blackjack, Video Poker, and popular slots.

Our online casino reviews show you which games are available for each app. Be sure to check out live dealer games! New technology allows you to join a table with a real dealer, just like you would on the floor of a Vegas or Atlantic City casino.

Horse handicapping sites and apps have been available for longer than most other gambling sites. The majority of states in the US allow for horse betting, but it doesn’t have to be done at the track.

With the popularity of US online gambling growing, there’s been a surge in horse betting. The best horse racing sites have expert analysis and picks, horse racing news, handicapping features, and live streaming.

DFS platforms are a little different than sportsbooks. Fantasy sports in the US is incredibly popular for the NFL season, but there are many more sports and leagues available.

US daily fantasy sports sites allow you to create lineups with all of your favorite players. You can compete for real money or enter free-to-play contests.

Fantasy sports platforms can get creative on what is offered. We usually think of DraftKings and FanDuel, but many more players have joined the game. Legalities of DFS sites vary by state, and it can get complicated in some jurisdictions. Those details will be provided on your state’s page.
