I have tested several social sportsbooks lately, but one sign-up offer truly stood out. Onyx Odds grants new players free virtual currency immediately, and there is no Onyx Odds promo code required to activate it.
Once you complete registration, your account is credited with 1,000 Onyx Coins at no cost. You can also take advantage of a first-purchase promotion that applies a 100% match to your initial Onyx Coin package. On top of that, the platform runs additional promos that help you accumulate more virtual currency and explore the full sportsbook experience. Read on for a detailed explanation of every available bonus. For a broader comparison of similar platforms, check out our main social sportsbooks guide.
Onyx Odds is a free-to-play sportsbook where bettors use virtual currencies (Onyx Coins and Onyx Cash) to make social sports predictions. It features major sports markets like the National Football League (NFL), National Basketball Association (NBA), Major League Baseball (MLB), general soccer, and international events such as Mixed Martial Arts (MMA), sailing, and auto racing. The table below shows the common betting markets across different sports.
| Sport/Category | Common betting markets |
| Soccer/Football (Global) | Match Winner, Draw, Over/Under goals, Both Teams to Score, Asian Handicap, Correct Score, First Goalscorer, Half-Time / Full-Time, and other Props (player goals, cards, assists) |
| College sports | Spread, Moneyline, Totals, Team props, Conferences/tournament futures |
| Mixed Martial Arts/Boxing | Winner, Round betting (which round ends), Method (KO, submission, decision), and Prop bets like “Will the fight go to decision?” |
| Auto Racing/Motorsports | Race winner, Podium finishers, Head-to-head comparisons (which driver finishes ahead), Fastest lap, and Qualifying bets |
| Other niche/International sports (Rugby, Cricket, Darts, Table Tennis, Esports, Sailing, Cycling, Golf) | Outright winner, matchups, round/leg totals, props, etc. |
The platform also features a live section for bettors to watch games and make predictions in real time. The reality here is that Onyx Odds focuses solely on sports betting. So if you're a social bettor who enjoys slots or table games, you won't find any of them here. Onyx Odds is available in almost all US states except the following:
Like any real sportsbook, outcomes are unpredictable, and everyone has an equal chance to get extra virtual currencies. And as noted earlier, Onyx Odds operate via two main virtual currencies: Onyx Coins (or Gold Coins) and Onyx Cash (or Sweeps Coins).
You can get these virtual currencies upon sign-up, via daily logins, mail-in requests, and available promotions on the site. Also, you won't find any Onyx Odds deposit offers as the platform operates under a sweepstakes model.
You can also purchase Onyx Coins bundles on the platform to get more virtual currencies. However, this process is completely optional; you can still receive other freebies on the site without making any purchase.
When you accumulate enough Onyx Cash, you can redeem it for a real prize. All you have to do is meet the minimum redemption amount (20 Onyx Cash), playthrough (1x), and verification requirements set by Onyx Odds.

Right now, you can enjoy two interesting welcome offers. The first is a free, no-purchase registration bonus of 1,000 Onyx Coins. Then, if you're interested, the platform gives a 100% match on your first Onyx Coins package purchase. Activating this offer requires using an Onyx odds bonus code. Here's how to get it:
Click the banners on this page to take you to Onyx Odds' official website. Sign up with your email and a password, and input the Onyx Odds promo code (it's usually applied automatically) to get a 100% match deal on your first Onyx Coin purchase. Complete your registration by verifying your account through SMS or email.
After verifying your account, the platform gifts you 1,000 Onyx Coins to make your sports predictions. If you're interested in getting more virtual currencies, you can opt to buy an Onyx Coins package from the site's virtual currency store. Once it's successful, you'll receive a 100% match on that first purchase. It's a one-time deal, and buying it is not mandatory.
Go to the sports section and make your picks using your bonus Onyx Coins or Onyx Cash. Remember, this 100% bonus is exclusive to your first Onyx Coins bundle purchase and is only available to new bettors. You'd also need to verify your identity before you can redeem the bonus SC and associated potential winnings.
You can also sign up for the Onyx Odds newsletter or follow the platform on social media. It occasionally offers bonus Onyx Coins or codes through email campaigns and holiday promotions. If you're curious to see how other platforms work, check my Thrillzz promo code guide, which covers this site's latest bonuses for new bettors.
Here are four ways you can make the most of the Onyx Odds freebies:
Make sure you know how this site works. Onyx Coins are for play only and can't be redeemed for prizes. On the other hand, eligible Onyx Cash winnings can be exchanged for real money prizes. Remember that you must play your Onyx Cash through at least once and meet any minimums before redeeming.
Since Onyx Coins are free, use them to learn the interface and try out different sports picks. It's a no-risk way to get comfortable within the platform. I used my free Onyx Coins to explore NFL and NBA picks without any worries. To be honest, doing this helped me refine my strategy.
You won't be able to redeem any prizes until you verify your identity. This is a quick step on your Account page (SMS or ID). Doing so early ensures there's no delay during the redemption process.
You'll find several Onyx Odds promotions that can get you more freebies to explore the platform's offerings. Watch out for things like parlay contests, boosted odds, or bonus virtual coins on social media. The social sportsbook is known for offering extra freebies during special sporting events. These pop up in banners on the site and on social media, so keep an eye out for them.
Just a heads-up: you won't find an Onyx Odds no-deposit bonus, since the platform operates as a social sportsbook rather than a traditional sportsbook. However, you can get freebies in the form of sign-up bonuses, first-purchase deals, and limited-time promos.
You should note that Onyx Odds is purely sports-based. However, if you enjoy casino-style games (slots, table games, and more), feel free to check my PlayFame promo code review.
Besides using an Onyx Odds promo code to double your Onyx Cash, here are other ways to get this virtual currency on the platform.
You can literally mail in a request to Onyx Odds. Send a handwritten note to the address listed on their site, and they'll often credit you with some free Onyx Cash.
Follow Onyx Odds on its social media platform. The team sometimes posts promotions or contests. For instance, sharing a promo tweet could get you bonus Onyx Coins or Onyx Cash. Keep an eye out for any giveaways or code announcements on their social channels.
As you play, you receive loyalty points or reach VIP tiers. Accumulated points can unlock extra Onyx Cash or perks. Some sites give bonus Onyx Cash when you hit certain point thresholds. Check the Onyx Odds promotions or VIP page to see what rewards your play level can fetch.
By combining these methods (free virtual coins, mail-ins, and your first purchase match), you can receive steady Onyx Cash rewards. It's all part of the sweepstakes gaming model, where you build your virtual currency balance without needing to use real money.
If you're looking for more gaming action beyond Onyx Odds, Spree is a compelling alternative. This operator offers dozens of slots and table games that you can play using virtual currencies. You can check my Spree promo code guide for details on available freebies.
Without any doubt, Onyx Odds is a reliable free-to-play sportsbook. It has different promotions that give you free Onyx Coins and Onyx Cash to explore its offerings and make sports predictions, starting with the decent 1,000 Onyx Coins as a free welcome bonus.
If you're ready to claim them, click the banners on this page, which will redirect you to the Onyx Odds welcome offers page. Register an account to get the sign-up bonus and enter a bonus code (which is usually applied automatically) to receive a 100% match on your first optional Onyx Coins bundle purchase. You can also browse our complete sites like directory for more alternatives.
