The best social sportsbooks and where they're allowed

Here’s a quick look at the top five social sportsbooks that deliver a smooth, exciting, and legal betting experience, covering everything from major leagues like the NFL, NBA, and UFC to international soccer and other niche sports.

Fliff – The most popular social sportsbook

Fliff: Pros & Cons

• Play for free or cash prizes
• Fantastic social sportsbook
• Major sports covered
• Great welcome bonus

• Limited minor sports

Visit Fliff

Where to play: 45 US states (except Washington, Hawaii, Idaho, Nevada, and Tennessee)

If you’ve been looking into social sports betting, you’ve probably heard of Fliff. This is one of the most well-known social betting sites, and there's no surprise about that. On my first visit, I was struck by the massive variety of sports available. You'll find everything from Soccer, covering major leagues like the NFL, NBA and MLB, Basketball and UFC to niche sports like cricket and even esports.

The betting markets are just as good, including moneylines, Playerprops, spreads, totals, parlays, and even live in-game wagers. New players will receive 100 Fliff Coins plus 1 Fliff Cash as a welcome bonus.

You'll also enjoy a sleek and modern design, and you can download the Fliff app or place bets on the website. I found the odds to be competitive too, with top-tier sportsbooks. However, state restrictions apply, so check your state eligibility upfront.

Thrillz – The best social betting app experience

Rebet – The best for social and peer-to-peer betting

Rebet Social Sportsbook: Pros & Cons

• Intuitive mobile application
• 60 major sports categories
• Social casino games
• Generous welcome bonus

• A few state restrictions apply

Visit Rebet

Where to play: Not available in Idaho, Michigan, Montana, Nevada, or Louisiana

Rebet is an innovative social sportsbook that brings a fresh vibe to sports betting. It features two unique betting modes: re-bet and peer-to-peer betting. The re-bet mode lets you copy bets from other players on your timeline, while the peer-to-peer mode allows you to challenge friends directly to see who’s better at predicting games.

I found Rebet to be one of the most interactive sportsbooks, it's more than just placing bets; it’s about engaging with the community, sharing picks, and seeing what others are betting on. New bettors will receive 100 Rebet Coins and 1 Rebet Cash as a welcome bonus to use on its selection of 60+ sports and leagues available, including NFL, NBA, NHL, MLB, NCAA, MMA, and more, so there’s never a shortage of options.

Sportzino – A feature-rich social sportsbook

Sportzino: Pros & Cons

• Player-friendly bonuses and promotions
• Sportsbook and casino products
• Intuitive, mobile-friendly website
• Cross-platform compatibility

• Zero table games

Visit Sportzino

Where to play: Available in most US states (excluding Washington, Idaho, Georgia, and Michigan)

Sportzino is one of the newest social sportsbooks making waves. It covers a wide range of sports markets, including football, basketball, baseball, hockey, and even esports. I found its parlay system and live betting features particularly engaging, truly giving it a Vegas-style sportsbook feel.

One of my favorite things about Sportzino is its massive welcome bonus, up to 170,000 Gold Coins and 7 Sweeps Coins just for signing up. You can collect even more through daily logins and various challenges.

Sportzino doesn’t have a dedicated app, but its mobile browser version runs smoothly so you won't miss a beat. However, some states have limited access to certain features, so check your eligibility before signing up.

Sports Millions – Great for straightforward betting

SportsMillions: Pros & Cons

• Variety of bonuses available
• Easy-to-use interface
• Reliable customer support
• Competitive odds
• Wide range of promotions for all types of players
• Seamless integration of casino games and sports predictions

• Limited availability in some regions

Where to play: Available in 40 US states (parlay bets restricted in some states)

If you’re looking for a simple, no-frills social sportsbook, Sports Millions is a solid pick. It also has no mobile app, but its website is well-optimized for smaller screens. With your welcome bonus of 1000 Gold Coins + 3 Sweeps Coins, you can enjoy wagering on sports options like football, basketball, baseball, tennis, and live sports events.

I noticed that Sports Millions doesn’t have as many advanced betting features as others I've listed, but it’s perfect when I want to make picks and have fun. However, parlay bets are restricted in certain states, so if you love multi-leg bets, you may want to try others I've mentioned. Also, players from the following states are not allowed: Alabama, Delaware, Georgia, Idaho, Kentucky, Louisiana, Michigan, Montana, Nevada, and Washington.

These are the best social sportsbooks for legal betting in the US

Social sportsbooks like Fliff, Thrillz, Rebet, Sportzino, and Sports Millions give you a fun and legal way to place bets on your favorite sports for free. So, whether you’re looking for peer-peer bets, app-only sportsbooks, or classic sports predictions, there’s a social sportsbook that fits your style.

As you've seen, each sportsbook has different restrictions by state, so check availability before signing up. And remember, you can enjoy placing bets without real money yet stand a chance to redeem eligible winnings.

So, which one will you try first? Let me know, I’m always up for a good sports betting conversation.
