Onyx Odds Review & Promo Code 2026

There were eight available betting markets during this Onyx Odds review. Other sweepstakes sportsbooks, such as ReBet, cover upwards of 30 sports, so Onyx Odds is a little behind the curve in this regard.

The good news is that the list of options is growing. From an initial line-up that included the NBA, NFL, NCAA, NCAAF, boxing, MMA, and the NHL, the oddsmakers expanded their remit to female tennis in early 2026.

That's a positive sign that the team is actively increasing its coverage while maintaining the current level of quality. That quality is evident in the lines offered on the current selection of eight sports.

Comparing like-for-like, the lines at Onyx Odds are, on average, half a point higher. For example, if the moneyline for the Baltimore Ravens is +1.5 at ReBet, it's likely to be closer to +2 at Onyx Odds. That means you're getting better potential returns for the same bet.

The odds, of course, can change, and the lines won't be better for every type of bet. However, because Onyx Odds only offers moneylines, totals, spreads, and parlays, it's able to keep its vig. low and odds attractive.

Onyx Odds is a little light on promotions compared to other DFS apps, but that doesn't mean you can't extract value from it. There isn't a daily login bonus or any of the other bonuses you expect to see at top sweepstakes sportsbooks.

There is, however, a mail-in bonus. Mail-in requests get you five Onyx Cash, which is the equivalent of five Sweeps Coins. You can also get 15 Onyx Cash for referring sports fans, as well as timely purchase bonuses.

There wasn't a VIP or loyalty program at the time of this Onyx Odds review, but the team has said there is one in progress. VIP perks are the mark of a world-class sweepstakes sportsbook, and something Onyx Odds would benefit from offering.

You can't purchase Onyx Cash directly. Instead, you get them free by purchasing Onyx Coins. Optional Onyx Coin packages start at $10 and go up to $500.

Along with all major credit/debit cards, you can purchase Onyx Coins and Onyx Cash with PayPal, MuchBetter, Trustly, and ACH bank transfer. Of those options, only ACH can be used to redeem Onyx Cash winnings.

How to Redeem

Onyx Odds has two virtual currencies:

• Onyx Coins = These are equivalent to Gold Coins, which means they're fun tokens that can be used to make sports predictions but can't be redeemed.
• Onyx Cash = Also known as free picks, Onyx Cash is the equivalent of Sweeps Coins. Onyx Cash can be used to make sports predictions and redeemed for prizes.

Only verified users can redeem prizes for Onyx Cash. Verification takes place automatically during the registration process, which is something you don't get at other social sportsbooks.

If the software can't verify your identity, you'll need to send the customer support team copies of your ID and proof of address. Once verified, you can redeem winnings once the tokens have been used once (1x playthrough).

The minimum redemption is 20 Onyx Cash, which is below the industry average. Although the minimum threshold makes it easier for recreational users to redeem Onyx Cash, bank transfers take between five and seven days, which is slightly longer than average.

Of all the areas for improvement, customer support is the one that needs addressing sooner rather than later. There wasn't a live chat feature at the time of this Onyx Odds review. Fortunately, the FAQ provides enough information to cover most basic issues.

When that's not enough, you can email (contact@onyxodds.com) or call (+1 334-471-4060). Unfortunately, the average response time for emails is 24-48 hours, and the phone line isn't monitored regularly.

Onyx Odds isn't packed with features. Unlike ReBet, which taps into the community aspect of social sports betting with P2P competitions and re-bet, Onyx Odds is much more like a traditional sportsbook.

That means you get direct access to pre-game and live betting odds. This no-fuss approach is complemented by the platform's mobile-first layout.

Everything has been streamlined and optimized for iOS and Android devices to the point that you can't access your account via desktop computers.

The only criticism in this area is that Onyx Odds doesn't offer an iOS or Android app, which is unusual for a company that's built its sportsbook for mobile devices.

That being said, the mobile site performs well on all browsers. The only issue is lag. Although infrequent, the software sometimes skips a bet. But that's somewhat understandable given that the system is updating hundreds of live betting odds in real-time.

The overall sentiment from the many Onyx Odds reviews online is that it offers competitive odds and an easy-to-use mobile site. However, users also say that redemptions could be quicker, and there are mixed views on the customer support service.

"Onyx Odds has been nothing short of impressive. Their customer service is genuinely top‑tier. What really sets them apart, though, is the depth and variety of their lines and props."

"I didn't give it a five because it doesn't have game logs or stats like other DFS apps do."

"I don't have any major complaints. Sometimes the platform lags a little, but with them being a new company and working out some kinks, it's understandable."

"Right now, one star because they don't have live chat or a number to call."

Although they're activated on request by the customer support team, you can keep yourself safe with these responsible gaming features:

• Purchase limits
• Wagering limits
• Loss limits
• Timeouts and self-exclusion

What's nice about these responsible gaming tools is that they can be applied to Onyx Coins and Onyx Cash.

Onyx Odds is a legit social sportsbook that's clearly aiming to replicate the experiences offered by its real-money counterparts. This means you don't get some of the social features you get at other sweepstakes sportsbooks, such as ReBet.

Instead, the mobile-first platform gives you instant access to competitive odds on any iOS or Android device. So, if you're someone who wants a clear view of the latest sports predictions markets without any distractions, Onyx Odds has you covered.
