Fact checked by: Sara Jane Gamelli

Several online sportsbooks offer a sports betting sign up bonus you can use on the sportsbook, often subject to certain terms and conditions, but how do you end up with the best welcome bonuses as a new sports bettor?

Choosing a site with a decent welcome bonus is one way to start. To do that, however, you need to know what bonuses are available and how they work. However, if you’re a sports bettor based in the United States, there’s an easier way: use my recommended social sportsbooks and get the best welcome bonuses easily.

Quick facts about sports betting sign up bonus deals

  • Most sports betting sites offer generous bonuses to all new users for signing up
  • Sports betting sign up deals often come as deposit match bonuses, no deposit offers, or profit boosts
  • Sportsbook sign up bonuses generally come with bonus terms as guidelines for using the bonus
  • US-based bettors can use social sportsbooks like Sportzino’s or Rebet’s to avoid the sports betting ban in most US states

Top social betting apps with sign up bonus offers

US bettors generally can’t use conventional online sportsbooks, as most states currently have legislation against sports betting. However, social sportsbooks are still generally legal in the US, and they often offer generous bonuses, sometimes rivaling some of the best sports betting bonus offers on traditional online sportsbooks.

Here are my top recommendations for social sportsbooks with an excellent welcome bonus to try as a sports bettor based in the United States

Legendz – Best social sportsbook with live casino

Legendz Casino
Legendz social casino
Legendz: Pros & Cons
  • Impressive welcome bonus
  • Intuitive desktop and mobile sites
  • No purchase necessary
  • Legal in 46 US states
  • High prize redemption limits
Visit Legendz Casino

When you sign up on Legendz, you'll get 500 Gold Coins and 3 Sweepstakes Coins free, plus a 10% bonus on your first optional Gold Coin bundle purchase. It is one of the top social betting apps that give a sign up bonus. While Legendz doesn't have Android or iOS apps like Fliff or Thrillzz, its web app works great on any device, including mobile. Along with a solid sportsbook covering various sports and leagues, Legendz also offers a fun social and live casino.

Sportzino – Best social sportsbook with sweepstakes casino games

Sportzino

Sportzino: Pros & Cons
  • Top welcome promotion
  • All-in-one social sportsbook and casino
  • Realistic sports betting experience
  • No table games
Visit Sportzino

Sportzino offers one of the most generous sportsbook sign up bonus deals I know. All new bettors get a welcome bonus of 170,000 Gold Coins and 7 Sweepstakes Coins, allowing you to make free sports selections on the site’s excellent social sportsbook with different sports and leagues, including the English Premier League, NBA, NFL, and NHL.

More interestingly, Sportzino features over 1,000 social casino games you can play using the same sign up bonus for the sportsbook, so it’s pretty much the most versatile welcome bonus we’ve seen so far. During my review, I played top social casino slots like Gates of Olympus and Coin Up Lightning without an initial Gold Coin bundle purchase, all thanks to my generous welcome bonus, so it deserves some flowers for versatility.

Rebet – Best social sportsbook with free sign up deals

Rebet
rebet-app-pro-contra-us
Rebet: Pros & Cons
  • Unique social betting features
  • Daily login bonus
  • Community-building app
  • Win real rewards
  • No real customer reviews yet

All new Rebet users get 100 Rebet Coins + 1 Rebet Cash for free to bet on sports games without an initial purchase, but that’s not the full extent of the site’s welcome offer. You can also claim the site’s generous first-purchase bonus that matches the value of your first Rebet Coin bundle purchase up to $100, and that is separate from the free Rebet Cash bonus bundled with all Rebet Coin bundle purchases.

Thanks to the bonuses, you can start betting on your favorite sports and leagues on the social sportsbook without an initial purchase. What’s more, Rebet offers excellent apps for both Android and iOS, allowing for a quick and slick native betting experience. Tell you what? For US bettors, Rebet remains one of the best sports betting apps with a sign up bonus we have around.

Fliff – Best social sportsbook for competitive odds

Fliff

Fliff: Pros & Cons

New Fliff users qualify for several welcome bonuses if they sign up with promo code BILFLIFF. For one, the social sportsbook offers 5,000 Fliff Coins + 1 Fliff Cash with no strings attached. Also, you’ll get $100 in Fliff Coins and free Fliff Cash when you spend $50 on Fliff Coin bundles, among a plethora of login bonuses, loyalty rewards, and referral bonuses.

Like most other sites in this category, Fliff has mobile apps for Android and iOS, offers an impeccable interface, and features competitive odds on top sports and leagues, including the NBA and NFL. With its generous sportsbook referral bonus that’s among the industry’s best, you can’t go wrong with Fliff.

Thrillzz – Best social sportsbook no deposit bonus

Thrillzz starts you off with 3,000 Thrillzz Coins and 3 Thrillzz Sweeps for free, just for signing up—no sports betting bonus codes or links required. Additionally, you get 100% extra on your first optional Thrillzz Coin bundle purchase, allowing you to make free sports picks on the site’s Android and iOS apps. It’s not the best sign up bonus on sports betting, but it’s not half-bad for a new sports bettor either.

Speaking of the social sportsbook’s app, you can bet on several prominent sports and leagues using the app, including the NBA and the NFL. Thrillzz features special betting modes like pre-match predictions and live bets, making it one of the most popular social sportsbooks among bonus hunters in the United States.

Examples of betting sign up bonus offers

Here are popular sports betting sign up bonus offers I’ve encountered on top sports betting sites and how they work:

💰 Deposit Match Deals

Deposit match deals are super popular on sportsbooks because they're so simple. They match a percentage of your first deposit, often up to a limit. Most give you 100%, turning your first entries into risk-free fun. An example is a “100% deposit match bonus up to $1,000,” which will reward you with bonus bets worth the full amount of your initial deposit up to a limit of $1,000. That way, you only receive $1,000 in bonus bets when you deposit over $1,000.

🎁 No Deposit Offers

No deposit bonuses are rewards given immediately after signing up with no upfront deposit or purchase requirements. This bonus often comes as bonus bets with a steep wagering requirement, but they at least give you immediate access to sports wagers for free. While conventional no deposit bonus sportsbook sites are relatively rare, most social betting sites almost always offer the bonus to all new users. For example, Thrillzz gives all new users 3,000 Thrillzz Coins and 3 Thrillzz Sweeps for free, even before you buy an optional Thrillzz Coin bundle. Pretty sweet deal, right?

🛡️ Risk-Free or No-Sweat Bets

Risk-free or no-sweat bets return the stake on your bets if they lose. It’s more or less insurance, guaranteeing you get at least your wager back, regardless of the outcome of your bet. Since you’ll get your stake back with the profits if you win anyway, you’ll often have to forfeit no-sweat bet bonuses if your initial wager wins. The upside to no-sweat bets is that the insurance makes it easier to bet a huge amount upfront, knowing you’ll get your stake back at least if the bet loses.

📈 Profit Boosts

Profit boosts are a unique form of sportsbook bonuses applied on the profits of your first winning wager, subject to specified terms and conditions. They typically come with a boost percentage and a limit. For example, you may see a “20% boost up to $100” bonus, which, in layman’s terms means you get 20% extra on the profits of any bets with a stake of $100 or lower. Profit boosts only apply to profits and not your entire payout, so you also want to keep that in mind. You’ll get the advertised 20% boost on whatever profit you get on your bet, and the social casino adds your original stake (without any boosts) to the new profit amount before paying it out as your total winnings.

Conclusion – Enjoy excellent sports betting on top social sportsbooks with sign up bonus deals

Nearly all sportsbooks have sign up bonuses, but not all can hold up to the available competition. I've done the heavy lifting by researching the sites with the best sign up deals. Jump on any of my social sportsbook recommendations, pick up a sports betting sign up bonus and get into raw sports betting action. You don't want to miss it. Go, go!

Sports betting sign up bonus FAQs

Most US states don’t allow real money sports betting, and consequently don’t allow you to claim most sports betting bonuses. However, social sportsbooks are generally legal in most US states, and you can claim many of our recommended sweepstakes sportsbook bonuses from eligible states.

🎉 Do sports betting sites offer welcome bonuses?

Yes. Most sportsbooks will have a sports betting sign up bonus for all new users to induce signups, with very few exceptions. Considering the abundance of generous sportsbook bonuses, you want to stick to sites with decent offers at least when choosing a sportsbook.

💰 Which sites offer the best sportsbook welcome offers?

The ultimate answer will depend on your requirements in a sportsbook and your preferred form of bonus. Note that if you live in the US, most conventional sportsbook bonuses will be unavailable to you, but you can always claim social sportsbook sign up bonuses, which are often more generous free virtual coin bundles.
