This is a pretty new sweepstakes casino and we certainly enjoyed all that we found in our Clubs Casino review. Just like Underdog Fantasy you can play here for free and even redeem SC winnings for cash prizes after meeting the site’s playthrough requirement. It’s also got a great rewards program which is something that Underdog Fantasy couldn’t manage. Just note that this is a social casino with around 800 slot games rather than any social betting odds. As a free welcome bonus you can immediately claim 10 free spins on the Zombie Circus slot as a new player.

Best Games like Underdog Fantasy
There are
new sweepstakes casinos
appearing all the time, but there aren’t too many
social betting sites
that Underdog Fantasy has. Plus that brand doesn’t even have any casino games in the first place. So what we’ve done here is to highlight the best games at our sites like Underdog Fantasy to give you a good idea of where to begin:
Lava Coins: This awesome 3 Oaks slot game can be found at MegaBonanza and its 2,000x multipliers should keep you more than entertained.
Big Bass Bash: A massive slot game from Pragmatic Play at Real Prize, this time featuring an eye-popping RTP of 96.71%.
Poker: This is one of the Stake Originals series of games found at Stake.us, and it gives you a simple way to play online poker with a house edge of just 1%.
Twin Win: You’ll love playing this exclusive High 5 slot at the High 5 Casino site. Why? Well, those multipliers of 10,000x will take some beating.
Fireball Inferno: NetGame came up with a top slot in the form of Fireball Inferno because it’s packed with respins and multipliers that go up to 1,320x. Give it a try at Clubs Casino.
Best Apps like Underdog Fantasy
While Underdog Fantasy has created a great social betting app, it’s actually fairly rare for sweeps casinos to develop their own apps. However, we’ve found the following top apps that give you another great way to play for free:

Best Underdog Fantasy Sister Sites
It’s often smart to look for a brand’s sister sites. After all, by looking at the
CrownCoins Casino sister sites, you can see casinos that are operated by the same parent brand so that you can enjoy a similar, but different way to play. However, you cannot really do this with Underdog Fantasy as it is a privately owned company with no sister sites. Definitely a social betting site like no other.
Pros & Cons of Sites Like Underdog Fantasy
By now you should hopefully understand the appeal of playing at these sites like Underdog Fantasy. But if not, here are the main pros and cons to help you decide where to play:
Pros & Cons

Each of these social betting and gaming sites will have to let you play for free. This means that we’ll be rating all of the brand’s offers for new and existing customers to see how well they perform this important function.
🤝 Customer Care
You will want to make sure that the social sportsbook or casino can help you out should something go wrong. As a result, we’ll be checking to see if customer service is available via live chat, email, phone or even social media.
💳 Payment Options
While you should always be able to play at these social casinos and sportsbooks for free, you should also be able to make secure optional purchases of Gold Coins packages with payment providers that you can trust.

I’ve shown you that Underdog Fantasy may be a true one-off, but it’s not the only site that operates with the sweepstakes model.
