Our Favorite Betting Tools and Features at Onyx Odds
Onyx Odds features a sleek web-browser app with a minimalist black and purple theme. The simple layout and intuitive menus make it easy to make sports predictions. Here are some of Onyx Odds’ features we appreciated:
Low Playthrough Requirement & Minimum Redemption Limit
After you’ve played through your Onyx Cash 1x, it becomes eligible for redemption. At Onyx Odds, redemptions start from just $20, which is a nice surprise seeing as at many social sportsbooks, the minimum redemption is $50 or even $100.
No Sweat Pick
Onyx Odds offers insurance on your first sports pick. If your favorite team loses or the player you wagered on fails to perform, Onyx Odds will refund your Onyx Cash.
Market-Beating Odds
Onyx Odds may not give away as many Sweeps Coins as other social sportsbooks, however, it makes up for it by offering superior odds. Onyx Odds has decided to attract new players by undercutting the competition, and its markets are filled with value.
VIP Program
Every time you make sports predictions at Onyx Odds, you’ll earn points and progress through the different VIP tiers. As a VIP player, you’ll qualify for exclusive rewards, including Onyx Cash gifts. Although there is no dedicated promotions page anywhere on the site, they do run promotions at various points throughout the year.
To keep track of these promos, you should follow the Onyx social media channels so you will find out the promos as they are released.
Helpful Responsible Gaming Tools
At Onyx Odds, you can set Onyx Cash and Coins daily wagering and loss limits, which are reset every 24 hours. Also, self-exclusion is available if you need to take a break or want to ban yourself from the social sportsbook. To enable these responsible gaming tools, simply email Onyx Odds at contact@onyxodds.com.
Our Experience & Score of Onyx Odds
We were a little disappointed that Onyx Odds didn’t provide any Onyx Cash when we signed up, especially when social sportsbooks like Sportzino give you $10 just for registering. The lack of a daily login bonus was also a shock.
Onyx Odds did slightly redeem itself courtesy of its $5 mail-in bonus and no sweat promo, where it will refund your sports pick if it loses.
We’ve got to hand it to Onyx Odds when it comes to prediction markets. Its live sports picks are on point, and you’ll find all your favorite prediction types, including moneyline, spread, total, and props. Also, there are plenty of events to keep things interesting, with markets for all NBA, NFL, and MLB games.

It is very convenient to purchase and redeem at Onyx Odds. The social sportsbook accepts Visa, Mastercard, and PayPal and doesn’t charge fees. Also, you can redeem cash prizes directly to your bank account within 72 hours via Trustly.
Customer support could use some improvements, as only email support is available. Going back and forth over email means it can take days to get minor issues fixed. It’d be nice if Onyx Odds added live chat.
When it comes to safety, we’re confident Onyx Odds is a secure sportsbook. It is operated by a US-registered company, verifies the accounts of all players, and geo-blocks users from restricted states. However, it should add a daily login bonus and offer Onyx Cash when you sign up to comfortably fulfill the no purchase necessary requirement.

Onyx Odds Sports Markets
Onyx Odds features sports prediction markets for all major US sports, including NBA, NFL, MLB, and even WNBA. Unlike other social sportsbooks, Onyx Odds is also planning on adding a variety of niche sports.
Onyx Odds is one of the best sportsbooks for live sports betting that we have come across. This means you can tune into games and make predictions as the action unfolds on the pitch or court. Live picks are a great way to keep games interesting because, trust us, if you take the over on an NBA totals pick, you will hang around until the 4th quarter.
This free-to-play sportsbook features a wide variety of pick types, including:
- Moneyline
- Spread
- Total
- Team Props
- Player Props
- Over/Under
- Half-Time and Full-Time
After comparing the odds between major social sportsbooks, Onyx Odds, on average, offers better prices, particularly on the NFL and NBA. However, you do need to factor in the lack of free Onyx Cash.
Virtual Currency at Onyx Odds
There are only two virtual currencies that you can bet with at Onyx Odds; Onyx Coins and Onyx Cash. Neither of these currencies have any actual monetary value away from betting on the site. Onyx Coins are used purely for betting for your own entertainment, and they can’t be redeemed for any real cash prizes. You are able to purchase more Onyx Coins if you run out of tokens, or you can get them as part of a bonus offer.
Onyx Cash is different as this can be redeemed for valuable prizes, but you cannot purchase any of these. The only way to increase your Onyx Cash bankroll is via bonuses or promotions. There is also a 1x playthrough requirement before you are able to redeem Onyx Cash for prizes.
Onyx Odds Banking Methods
Even though no purchase is necessary to make sports predictions at Onyx Odds, you have the option of purchasing Onyx Coins and receiving complimentary Onyx Cash. This social sportsbook accepts Visa, Mastercard, PayPal, and MuchBetter. There is a wide range of Onyx Coins packages starting from $10 and going up to $500.
After you’ve played through your Onyx Cash at least 1x, you can redeem it for a cash prize. The minimum redemption is $20, and the only available payment is an online bank transfer via Trustly. There are no fees, and you’ll receive your prize within 3 days.
Onyx Odds Support and Contacts
Onyx Odds only offers customer support via email (contact@onyxodds.com), and you can expect a reply within 24 hours. Even though it’s a free-to-play social sportsbook, it should still offer live chat support or at least a chatbot.
Onyx Odds is also active on Facebook, X, and Instagram. Even though these aren’t official customer support channels, you can shoot the sportsbook a message and typically get a reply within a few hours.
Is Onyx Odds Legit?
Onyx Odds is legit. It’s operated by Onyx Games LLC, a New York-registered and headquartered company. Onyx Odds appears to be following all sweepstakes regulations.
It verifies players’ identities to ensure they are not underage or from restricted stakes and doesn’t allow you to purchase Onyx Cash. Onyx Odds also offers an alternate method of entry via its mail-in bonus. However, if the company wants to play it safe, it should also offer a daily login bonus to fully comply with the no purchase necessary condition.
Regular Deals and Rewards at Onyx Odds
Onyx is lacking when it comes to regular deals and rewards. It doesn’t provide discounts when you purchase Gold Coins, and there isn’t a daily login bonus.
However, you can get bonus Onyx Cash via the sportsbook’s mail-in bonus. For every handwritten letter you send, you’ll receive 5 Onyx Cash. You can claim this bonus up to 100 times. Head to the Sweeps Rules section to see all the steps involved. There is also a no sweat promotion where you get your Onyx Cash if your first sports pick doesn’t win.
How Does Onyx Odds Compare to Other Sportsbooks?
The obvious thing to note when comparing Onyx Odds to other sports betting sites is that it is not a traditional sportsbook. This is the reason it is legal in states and regions where sports betting has not been legalized yet. Social sportsbooks are still a relatively new concept for US bettors and allow you to wager on sports in a non-traditional sense as you are using virtual currency and not real money. However, at sites like Onyx Odds, you can redeem this virtual currency for real prizes.
Onyx Odds Review Verdict
Onyx Odds is a good option if you are in a state where sports betting is prohibited or are under 21. However, due to the lack of ongoing bonuses, you are better off trying other similar social sportsbooks like Rebet and Fliff, which provide free daily Sweeps Coins.
