✅ Social media competitions and weekly tournaments available

Featuring plenty of social media competitions, 24/7 customer support, and an iOS app rated 4.8/5 stars, the site has a lot of perks for new and returning players. Add in the generous daily login bonus that increases up to 40,000 CC and 1 SC on day seven, and it’s clear to see why CrownCoins is fast becoming a fan favourite.

💬 User review:"Great games, and I've been winning a lot. My redemptions come within a day or two. Best platform so far.” ⭐ Vickey L., Trustpilot review, March 17, 2025

💡 Editor’s insight: “Although the CrownCoins app is only available on iOS devices, a 4.8 star rating is really impressive considering that mobile apps for sweeps casinos aren’t always available. With a rating like this, it’s one to check out.”

3. RealPrize – Best loyalty program

Pros

✅ Seven-tier rewards program with multiplier purchases

✅ Available in 45+ states

✅ Largest refer-a-friend bonus of our top picks (up to 200,000 GC and 70 SC)

Cons

❌ No mobile app available

RealPrize is one of the best sites available for rewards. With a seven-tier loyalty program to progress along and no deposit bonus of 100,000 GC & 2 SC for signing up, the initial perks are lucrative. Prizes range from birthday gifts, gold coin multipliers and exclusive games to merchandise gifts and more. In addition to this, you can get a daily login bonus of 5,000 GC and 0.30 SC. Compared to the Hello Millions daily bonus (1,500 GC and 0.20 SC), you can see why RealPrize is the best site for rewards.

BetRivers – Our best real money online casino

Pros

✅ An above-average 1,600 games from NetEnt, IGT, and more

✅ The lowest casino wagering requirements at 1x

✅ Withdraw real money wins instantly with Play+

Cons

❌ Could provide more table games beyond the current 50

BetRivers tops our list for real money casino gambling. It's also a great brand overall, with a successful sports betting site in the US. The casino's 96.96% payout rate is a good edge on the 96% industry average. I liked that over 80 slot games are featured as hot for having the highest payouts in the previous hour of play. Titles like Kronos and Slingo Fluffy Favorites peak well above 600x your stake.

💬 User review: "By far the best sportsbetting, casino, signup bonus, referral bonus, and customer service. Draft Kings and Fanduel are close but BetRivers is my favorite. I had a referral that had expired but they overrode it and gave me my bonus. The slots are great. The sportsbook is great. Love this casino in person. Dont waste your money anywhere. Come here. Payouts are quick too and easy sign up. All around A+." 5/5 ⭐ Brent G., Trustpilot, August 28, 2024

💡 Editor's insight: "BetRivers Casino gets some player feedback around a low chance of payouts. Digging deeper, though, I've noted the casino is competitive on payout rate overall, with a higher than average win rate to players. It's important to check the RTP of a particular game, as some payout more than others."

FanDuel – Best for sports betting

Pros

✅ The most popular sportsbook in the US, with over 17 million users

✅ Top gambling app rated 4.7/5 and 4.9/5 on the Play and App Stores

✅ More ways to win, with 10+ unique bets like Same Game Parlays and partial game odds

Cons

❌ No loyalty program for sports bettors

FanDuel is an established US gambling site currently available in 37 states. It's backed by one of the world's largest gambling companies, Flutter Entertainment, which owns Sky Betting & Gaming, and PokerStars. FanDuel offers sportsbook, casino, fantasy, and racebook betting. I was pleased to find the sportsbook offering live streaming in over 20 markets. I also rate FanDuel for bet innovations. FanDuel's 'Super Boosts' enhance the odds on bets with two or more outcomes. The Same-Game Parlay allows you to bet on multiple outcomes on a single game.

💬 User review: "They have a lot of different games to choose from, and they are constantly adding new ones. Each week you will find several new games have been added, usually one or two a day at least. Also, their processing time for withdrawals is by far the quickest I have come across yet." 5/5 ⭐ Derek H., Play Store review, February 25, 2025

💡 Editor's insight: Some bettors report issues with cashing out winning bets and suspended accounts. However, reading the terms of bonus bets and promotions is important. Your deposits, bet types, and withdrawals must all comply to receive your winnings quickly. Account suspensions are rare, but FanDuel’s responsible gambling protections can pause an account if the team is concerned someone is chasing losses.

DraftKings – Best for online slots

Pros

✅ Play 800+ slots from top game makers NetEnt, IGT, and more

✅ High 97.05% win rate - amongst the best payouts in the US

✅ Easily access your bonus funds with 1x playthrough requirements

Cons

❌ One of the lower value bonuses of our top US casinos

DraftKings is one of the top gambling brands in the US, offering Daily Fantasy Sports, online casino, and sports betting. It also tops our list of best casino gambling sites for exclusive games. With 70+ titles, including 40 unique slots games, the site has far more than the average 20 or so exclusives you'll see at other casinos. I highlighted 2 Tribes, which has a low entry bet of $0.40, Rocket, and Dollar Up! The lobby also connects to progressive jackpots that run across your state. There were prizes up to $400k when I last checked the site.

💬 User review: "Where DraftKings truly shines is their rewards program. It's simply astonishing. You'll always feel appreciated whether you're a casual player or a high roller. The tiered rewards system is generous, offering everything from free bets to exclusive VIP experiences. As someone who has experienced my biggest wins with DraftKings, I can confidently say that the rewards and promotions take the thrill to a whole new level." 5/5 ⭐ Chris M., Trustpilot review, October 9, 2024

💡 Editor's insight: DraftKings Casino gets some player feedback around the likelihood of payout and issues withdrawing. However, this is a common comment against most online casinos and usually reflects players who've misunderstood sign-up or bonus terms and conditions.

US states where online casinos & sports betting are legal

Pennsylvania, Michigan, New Jersey, West Virginia, Delaware, Connecticut, and Rhode Island have all legalized online casino and sports betting. What this means is real money online gambling sites available in these states are regulated at state level.

With this comes many benefits and protections that sites operating from offshore can’t offer you. This includes ensuring games are fair and that gambling sites protect your funds, data, and personal information correctly. Generally it means fairer, better quality betting with more financial protection.

Other US states where online sports betting is legal

The following states have legal online sports betting but have yet to legislate for online casino gambling. They include New York, Florida, Virginia, and Illinois. The best online betting sites in these states offer thousands of bets across hundreds of events and sports markets, from NFL to NBA, golf, tennis, NHL, and college games.

Sports betting online is regulated at the state level, so you are protected by laws for safe practice and fair gaming, as well as data and banking security to keep your personal information and finances safe. Gambling online also has lots of benefits for speed of play, with features like live and in play betting that let you wager as the game plays out, early cash out to claim a bet while the outcome is in your favor, and fast to instant bet settlement speed to get to your winnings faster.

States yet to legalize gambling

Of the remaining states, some are closer to legalizing gambling than others. Nebraska, Oklahoma, and Alabama all have gambling related legislation that has moved in 2024, while not getting to or through the voting stage. Nebraska introduced LB13 on July 25, which would authorize Nebraska’s racinos to provide online sports betting. Further debate on the bill won’t happen until at least January.

At the other end of the spectrum, it’s highly unlikely that Utah or Texas would legalize gambling owning to strong political opposition in the states. Similarly Idaho, Alaska, and South Carolina have seen little movement towards legislation in recent years.

• September 12, 2024 - Federal Sports Betting Bill proposed: The SAFE Bet Act would require all state level sports betting to be authorized by the Department of Justice. Raised by New York Rep. Paul Tonko and Connecticut Sen. Richard Blumenthal, the act, if passed, looks to enforce standards for gambling and advertising practice at a federal level.
• September 9, 2024 - New York wagered $1.4bn on sports betting in August: The New York Gaming Commission reported New York’s online sportsbooks generated $1.4 billion for the month, up 27.3% year on year. FanDuel and DraftKings had the lion’s share of the August handle.
• August 28, 2024 - Record number of Americans gambled in the last year: For the first time, a survey has shown the majority of American adults participate in gambling, with 55% of people reporting they did so in an American Gaming Association survey. This figure is an all-time high, and double the 22% gambling in 2021 in the post-pandemic low.
• August 13, 2024 - Missourians can vote to approve sports betting in November: Voters in Missouri will have a say in the November 5 ballot on sports betting in the state. 180,000 signatures were gathered on a petition filed with the Missouri Secretary of State, enough to secure Missourians a stake in the November vote.
• July 25, 2024 - Nebraska online sports betting unlikely until 2027: The introduction of Legislative Bill 13 would authorize Nebraska’s racinos to offer online sports betting. However, an amendment to the bill allowing voters to approve the move in an upcoming ballot pushed the provision past the fall election. The next opportunity would be the 2026 midterms.
• June 17, 2024 - Supreme Court shuts down Florida sports betting challenge: Two parimutuel betting companies were seeking to undo federal approval for the gaming compact between Florida and the Seminole Tribe. The legal case had been taken to the Supreme Court, but the petition was denied. This leaves the legal betting market in the hands of the Seminole and Hard Rock.
