Fliff and Onyx Odds are two popular social sportsbooks for U.S. bettors.
At first glance, they are very similar in what they offer. However, there are some key differences that we will point out. In this article, we compare Fliff vs. Onyx Odds, break down their similarities and differences, and reveal which is best for players in 2026.
Fliff vs. Onyx Odds: The similarities
Besides sharing common aspects such as a dual-currency system, competitive odds, bonus offers, and available sports markets, there are also some unique aspects to note.
Both Fliff and Onyx Odds are mobile-only platforms that offer dedicated mobile apps, but no desktop versions.
It can be hit-or-miss whether a social sportsbook offers a VIP/loyalty program. However, both Fliff and Onyx Odds offer them. The more picks you make, the more benefits you will receive.

Fliff vs. Onyx Odds: The differences
Both Fliff and Onyx Odds have apps, but while you must download the Fliff app to access the social sportsbook, you have the option to play at Onyx Odds directly from your mobile browser.
The redemption process
Like many other social sportsbooks, you can redeem Onyx Cash or Fliff Cash for gift cards and real-money prizes.
At Fliff, you must play through your Sweeps Coins (known as Fliff Cash) once and hold at least 50 to make a gift card or cash redemption.
At Onyx, you must play through the Onyx Cash once and only need 20 to make a redemption. This is one of the lowest redemption thresholds that we have seen on social betting sites.
While the redemption threshold is lower at Onyx Odds, funds can take up to 10 days to reach you, whereas at Fliff, you are typically paid within five. Fliff also offers more gift card options at places such as Domino's, Chipotle, Lowe's, and even Airbnb.
We also have a wealth of information for real-money online sportsbooks and have reviewed the more popular ones.
Sports and betting markets
Both Fliff and Onyx Odds cover major sports leagues, including the NFL, NBA, MLB, NHL, and more. Each also has a good range of betting markets.
One aspect in which Onyx Odds stands out is its coverage of less popular sports. It covers more niche options than Fliff does. For example, you'll find better coverage of women’s tennis and European soccer leagues.
Profit boosts
Both Fliff and Onyx Odds offer profit boosts, which give better odds on picks for bigger payouts. However, they do not work the same.
At Fliff, there is a dedicated 'Boosted' tab that shows all of the current profit boosts. At Onyx Odds, the boosts are part of its promotions and are not always available.
The DFS factor
While both are social sportsbooks, Fliff also offers the option to toggle to the daily fantasy sports (DFS) section. There are daily pick ’em contests where you can win real money by competing against other players.
PlayersBest verdict: Fliff is the winner
This was a tough one, as each social sportsbook has its pros and cons. However, we went with Fliff because it's a more established social sportsbook. The DFS option offers more profit boosts, faster payouts, and a wider range of gift card possibilities.
We like Onyx as well, though. If you appreciate lower redemptions and more betting options on less popular sports, it may be the social sportsbook for you.
