Onyx Odds reviews
explained, the online sweepstakes and social betting market in the US is becoming almost as crowded as the social casino scene in 2025. As a result, the brands and sites constantly need to find ways to get through the noise with no purchase welcome offers and purchase incentives.
When I signed up for Onyx Odds, I was welcomed with their new October offer — a 100% purchase match worth up to 100 in Onyx Cash Free Picks. It’s a nice boost for anyone just getting started, basically doubling your first buy so you have more to work with when exploring different sports markets.
The Free Picks themselves are easy to use and a good way to test the waters. You can make predictions and get a feel for how the platform works without putting too much on the line. They can’t be redeemed for cash directly, but they’re great for learning the ropes before moving on to Onyx Cash, which is what you’ll eventually use to redeem prizes.
What I like about this offer is how simple it is. There’s no confusing fine print or complicated setup—just make your first purchase, and Onyx matches it. It gives new users a fair start and a reason to play around with different options early on. For a social sports platform, it’s a straightforward and generous welcome.

Top tips for using the Onyx Odds promo code USA
Having used this bonus, here are my top tips to help you get the most out of it:
🆔 Verify Your ID and Phone Number Immediately
You don’t need to verify your ID or phone number to unlock the welcome bonus, but doing so straight away is smart. Only verified accounts can access purchase promos and ongoing rewards, so it pays to get this step done early.
🎲 Bet for Free Before You Spend More
Your purchase match from the welcome promo gives you a chance to test the platform without overcommitting. Make the most of these free plays to explore the different markets and learn the ropes before considering any extra purchases.
🏈 Stick to Sports You Know
If you want to maximize the value of your Free Picks, focus on sports and markets you understand best. Even though you’re playing in a sweepstakes-style setup, you’ll still enjoy better results if you apply your knowledge to familiar events.
While the Free Picks are a great way to get started, remember that additional bonuses usually come with Onyx Coin purchases. Play within your limits, and avoid chasing bigger bundles if they stretch your budget.
Redeeming winnings with Onyx Cash (SC) can take some time compared to traditional sportsbooks. Patience is key—treat the Free Picks as a fun way to build your balance slowly rather than expecting instant payouts.
Frequently asked questions about the Onyx Odds bonus for US players
Have you still got a few questions about this bonus? Hopefully, I have covered all of the facts for you with my answers below:
1. Who can claim this bonus?
To be able to legally create a new account here and claim the welcome offer, you need to be over 18 and a US resident. However, players in the following locations cannot access the site:
- Idaho
- Louisiana
- Michigan
- Montana
- Nevada
- Alabama
- Colorado
- Tennessee
- Washington
2. Do I need an Onyx Odds bonus code?
No, as things stand right now in November 2025, you don’t need a promo code to unlock the “100% purchase match for up to 100 in Onyx Cash Free Picks” deal. If that ever changes, we’ll display the valid code for you in the banners on this page.
3. What can I use the bonus for?
When you claim this offer, whatever you spend will be matched by the platform, which you can use to place social sportsbook wagers. Just to be clear, this isn’t an Onyx Odds social casino promotion; it’s tailored for the sweepstakes sportsbook, where you’ll get to back your favorite teams and events at competitive odds for fun.
4. Can I win real cash with the welcome bonus?
No, you can’t. The welcome bonus strictly provides Free Picks, which have no cash value and can’t be redeemed. However, Onyx Cash gotten through purchase promos
can
be converted into real prizes, provided you play through it once by staking on sports picks. If your focus is on prizes, you might also want to check out other
free-to-play casino games that pay real cash.
Loyalty programs and other Onyx Odds sweepstakes offers
One thing you'll note when you check out the Onyx Odds homepage is the section about VIP perks. Active players who place regular social bets can collect VIP points, which can then be used to unlock VIP benefits and special promotions. I also checked to see if there were any daily login rewards, but at the time of writing, there wasn't a daily reload bonus, which is unusual for a social sportsbook, especially as one of the
new SC casinos.
If you want to get free Onyx Cash, there are two main ways to do so:
- Purchase promotions:
Get Onyx Cash (SC) as a free bonus when you (optionally) purchase Onyx Coins (GC) on the site.
- Alternative Method of Entry:
Send a mail-in request to the brand’s NY office to receive free Onyx Cash (SC).
Onyx Odds bonus for USA - Overall conclusion
At the end of the day, this bonus is good enough to get you started with fun sports picks, but I wouldn’t say that it blew me over with its generosity either.
The new welcome offer of “100% purchase match for up to 100 in Onyx Cash Free Picks” gives you a nice head start and enough to play around with, though a little extra variety would have made it feel more rewarding. All in all, Onyx Odds has a lot of potential, and I could see it becoming a very popular social betting site.
100% purchase match for up to 100 in Onyx Cash Free Picks
Daily picks from betting experts on odds boosts and casino promos
The welcome offer at this social sportsbook online now gives the opportunity to claim the 100% purchase match for up to 100 in Onyx Cash Free Picks as a bonus upon registration. For context, these coins function like Gold Coins (GCs) on most other social casinos and social betting sites. This gives new players a real chance to test the sportsbook with extra value right away.
To claim this bonus, you just need to register with the following details: - Email address - Username - Password - Full name - US phone number - Address - State - Date of birth Once you have registered, you will get your bonus straight away after making your $10 deposit and you can start using them to back your sports picks for fun and for free. However, to get full access to your account, including purchase promotions and prize redemptions, you will need to verify your ID to ensure that you are over 18 and a US resident (except in Louisiana, Michigan, Montana & Nevada).
As the no deposit welcome offer consists only of Onyx Coins, you cannot withdraw or redeem them, as these coins have no real-world value. However, with the Onyx Coin purchase promotions, you can get free Onyx Cash, which is this site’s answer to Sweeps Coins (SC). If you play through your Onyx Cash at least once on sports picks, you can redeem it for cash prizes. However, redemptions can take up to 30 days, which is much longer than the average for a sweepstakes sportsbook site in my experience.
The main thing to avoid here is trying to sign up on your desktop browser. As I told you in the main body of my review, this social sportsbook works on mobile browsers only. If you try to register on a desktop browser, it will either let you get so far but ultimately reject your registration. Or, in the best case, a message will appear telling you to use a mobile device.
In summary, this bonus is OK if you’re fine making sportsbook picks for entertainment purposes only. However, I do feel it’s a shame that you don't have any Onyx Cash as part of the free welcome offer. You have the option to make a first purchase and receive a decent amount of Onyx Cash for free, but this is only suitable for players who want to spend money on the site.
