Visit Legendz Casino

Next on our list of the best sweepstakes sports betting apps is Legendz. This legendary brand knows what it means to offer an immersive sweepstakes experience, judging by its extensive casino gaming and sports betting sections.

When it comes to sports betting, this site has over 30+ sports game categories, including major US leagues like the NBA, NHL, and MLB. The sports betting markets are also just as comprehensive. We scoured through several matches, and each one had a great selection of betting options.

Its bonus offers are also pretty decent, especially its sports betting free bonus no-deposit offer of 500 Gold Coins and 3 Sweeps Coins.

While Legendz has yet to have a dedicated mobile app, its website works perfectly when accessed using a phone. The website has a simple layout and is well-categorized, making navigation a breeze.

Legendz is currently legal in 43 US states.

Onyx Odds – A dynamic sportsbook for data-driven picks

Pros & Cons of Onyx Odds

• Easy-to-claim welcome bonus
• Great range of props picks on individual matches
• Solid range of sports markets supported

• Limited promotions for existing customers
• No desktop version available

Visit Onyx Odds

Onyx Odds provides a streamlined and efficient sports betting experience that caters to fans of major US leagues. With a strong emphasis on prop bets and detailed statistical comparisons, the platform makes it easy to dive into wagering on NFL, NBA, MLB, and NHL contests. As you navigate its mobile-optimized website, you’ll appreciate the clarity of odds and the robust selection of over/under and player-specific wagers.

New customers are welcomed with an offer of 1,000 Onyx Coins plus an additional bonus of 25 Onyx Cash when you complete a qualifying deposit. This solid kickoff bonus, paired with regular challenges and a leveling system, ensures that every pick feels rewarding.

SportsMillions- also offers an impressive sports betting experience

SportsMillions: Pros & Cons

• Massive game library, with over 800 options to choose from.
• Daily login rewards and promotions.
• Play completely for free.
• Easy-to-navigate, user-friendly interface.

• No formal VIP or loyalty program for long-term players.

Visit SportsMillions

Wrapping our list is SportsMillions, a one-stop destination for both casino gaming and sports betting. Well, let’s take a closer look at what this brand has to offer when it comes to sports betting.

SportsMillions has two sports betting sections: the Blitz’em and Pick’em section. The Pick’em section caters to daily fantasy sports, so we’ll skip that for now.

When it comes to the Blitz’em section, which caters to social sports betting, this operator offers sports picks in a decent selection of sports games, particularly in three major leagues: MLB, NFL, and MLS. The sports betting markets across the matches in these sports leagues are pretty decent.

SportsMillions’ bonus offers are also pretty decent, especially its 1000 Gold Coins and 3 Sweeps Coins welcome bonus. This is enough to kick off your sports prediction experience as you claim more bonuses.

We also like that SportsMillions has a dedicated mobile app. This makes it more convenient for bettors, especially those using smartphones, to make sports picks on this site. However, this app is only available on the iOS Apple Store, which is a bit of a downside for Android smartphone users.

SportsMillions is currently legal in 39 US states.

Fliff- another excellent social sportsbook option with a decent selection of sports games

Fliff: Pros & Cons

• Cash prizes available
• Picks for major sports
• Free to play
• Available in most states
• Exclusive promo code: FLIFFSTRAFE

• Minor sports not featured

Visit Fliff

Next up, we have Fliff, another solid sweepstakes sports betting app. This brand offers sports betting in 9 major US sports leagues, including the NFL, NBA, and NHL, to mention a few. The sports betting markets across these games are also quite extensive, with each match having a good number of betting options, from the classic moneyline bets to total bets, spreads, and more.

One of our highlights about this social sportsbook is its social betting features, like sports pick sharing.

Like SportsMillions, Fliff also has a decent selection of bonuses. New bettors are welcomed with a sign-up bonus of 1,000 Fliff Coins and 1 Fliff Cash.

One important thing about Fliff is that it’s an exclusive sweepstakes sports betting app. You won’t find anything on its website, but instead, you’ll be directed to download its app. This is a pro as it’s more convenient for players, but it is a bit of a downside for those who prefer betting on the website. You can download the Fliff app on the Google Play Store and iOS Apple Store.

Fliff is currently legal in 45 US states.
