I took a fresh look at Onyx Odds, and the site now has a new welcome deal that’s worth mentioning. New players can get a 100% match on their first purchase, up to 100 in Onyx Cash Free Picks. It’s a simple offer that gives you a little more to work with right from the start.
Once your first purchase goes through, Onyx Odds matches it automatically, so you’ll have extra Free Picks ready to use. It’s an easy way to explore different sports and test the platform without putting too much on the line. It’s a fair and uncomplicated bonus that gives new players a boost while they get familiar with the site.
Bonuses have long been the bread and butter of social betting, where cash bets are prohibited, and sports picks are powered by virtual coins only. Sites like Onyx Odds advertise promotions because they a) want to draw in new players and b) offer sports picks access on a no-purchase-necessary basis.
When I set up my account with the mobile-only site, I received a ‘Spend $10 get 100 in Free Picks‘ first purchase deal, which offers new players who have never made a purchase before the chance to get 100 Free Picks when they register and spend $10. But that’s not all when it comes to what Onyx has to offer.
New users will get 200 in Bonus Picks when they spend $10 with an affiliate signup link. These bonus picks are spread across 4 days.
Like Rebet – a close Onyx Odds competitor that offers 60 different sports and 3,000 betting markets – Onyx Odds has a two-tier coin system in place, with “Onyx Cash” being the site’s upper-tier, sweepstakes currency.
When collected via social bets or Onyx Odds bonus codes, Onyx Cash can be redeemed for real-world prizes once minimum redemption thresholds have been met.
Unlocking your free, just-for-fun Onyx Coins is a pretty simple procedure. I managed to get mine by:
It may seem a little confusing at first, but Onyx Odds is a website (i.e., not an app) that’s playable only from mobile devices. This means you can only sign up from a phone or tablet.
Less confusingly, you can sign up here in seconds simply by hitting the blue “Sign Up” button and providing your email address and a few personal details.
Next, I was asked to verify myself via a US mobile number or email. I opted for my cell and was sent an SMS verification code, but wasn’t asked for any Onyx Odds bonus code to redeem my promotion.
Finally, I logged in with my new details, headed straight to my “Account” page, and found that I qualified for the first purchase promo ‘100% purchase match worth up to 100 in Onyx Cash Free Picks.’ What I can say is that this optional first-purchase promo is available right now, and although purchases aren’t required at Onyx Odds, the offer is worth looking into.
Jumping right into the T&Cs after claiming, I found that Onyx Odds casino bonus codes aren’t required in most regions right now – though the site is completely off-limits in AL, CO, ID, LA, MI, MT, NV, TN, and WA – which is a lot of states. What’s more, the rules regarding codes and bonus amounts could be subject to change at any time.
Covers multiple popular sports. Has a live sports feature. Available in 45 states. T&Cs and 18+ apply
After spending quite a bit of time tapping around Onyx Odds’ site on my phone and playing through this bonus, I’ve learned a few things – and I want to share them with you guys.
If you’re going after this offer, then I reckon you can get maximum enjoyment out of it by:
Onyx Odds isn’t the easiest social betting site in the world to understand. If you haven’t played with Rebet or any other, longer-established social sportsbooks before, it’s advisable to shape up what’s what before dropping any virtual-coin-based bets.
I found that here, Onyx Coins can only ever be played for entertainment purposes, and are never prize-redeemable. They can be collected by making sports picks, claiming Onyx Odds’ promo codes and bonuses, or by purchasing optional Onyx Coins packages from the “Purchase” page.
Conversely, Onyx Cash is a sweepstakes-style currency that can be redeemed for real-world prizes, but can’t ever be outright bought. It can only ever be collected through social bets, or by claiming Onyx Cash bonuses – some of which I’ll pick apart in a bit.
As Onyx Coins are free-to-play and never-redeemable, they make for great practice coins – and are ideal if you’re a social sportsbook noob looking to make some trial-and-error sports picks.
If you came here to stack up Onyx Cash and chase IRL prizes, mind, you might be a bit disappointed that this offer won’t set you up with any free Onyx Cash from the get-go. For those of you who fall into that camp, see my next tip…
Onyx Odds is always free to play at, but if you feel like boosting that virtual coin stash, or you’re keen to claim some free Onyx Cash, I’d suggest taking advantage of the site’s optional purchase bundles.
Of course, only Onyx Coins can ever be bought outright. But guess what? You’ll qualify for a 100% purchase match as a sort of bonus with your first optional buy-in. Packages start from $10 for 10,000 Onyx Coins with a 25 free Onyx Cash bonus. They then go right the way up to $500 for 500,000 Onyx Coins and a 500 free Onyx Cash bonus.
One frustrating aspect of the site is that you won’t be allowed to make an Onyx Coins purchase, or redeem any Onyx Cash for prizes, until you’ve satisfied the site’s ID-verification requirements. To be fair, though, this is standard across most sweepstakes sites, but it can still feel annoying.
Verification can be done at any time, so I’d suggest heading to your “Account” page and completing your checks ASAP, to avoid unwanted delays later on.
Just as you won’t need any Onyx Odds promo code to claim this brand’s sign-up bonus, there are a few other codeless promotions up for grabs here, too – and sometimes, these can be played in conjunction with your welcome offer.
Examples include “Parlay Picks” and boosted odds, both of which are occasionally available on selected live games. I didn’t spot too many other bonus options here, though, sadly…
Unlike Rebet and other social sportsbooks, Onyx Odds hasn’t been around for a massive amount of time. And of course, very little has been written about their bonuses during that time.
I’ve found that players seem to be frequently confused by the same old T&C chestnuts here. So, allow me to set the record straight. Here are some typical FAQs:
So long as you meet the eligibility requirements set (aged 18+ and residing in a state where Onyx Odds operates), you should get the 100 in Free Picks at sign-up after making your first purchase.
Nope. One thing I’m 100% certain of is that Onyx Odds is a sportsbook-inspired, social betting site only. They don’t offer any Vegas-style social casino games at the time of writing, and it’s unclear whether they’ll launch any in the future, either. I’d head to Stake.us – or maybe McLuck – if that’s the sort of thing you’re after.
Yes, absolutely. This is a free-to-play social sportsbook, meaning there are always avenues for collecting free Onyx Coins and Onyx Cash. I’ll talk more about some of these in the next section.
With no promotions section on the site, you may be wondering what Onyx Odds has to offer to existing player. Thankfully, they do have a bespoke VIP program, where active players can collect points, and when these points accumulate, special bonuses and perks will be unlocked.
After digging around in their “Sweepstakes Rules”, I also unearthed one or two free-to-claim bonuses, including:
It’s possible to get your hands on some free Onyx Cash (though how much is unclear) by mailing an entry request in an unfolded, unlined envelope to the site’s US address in Manchester, New Hampshire. Your request must be handwritten and can only be sent a maximum of 100 times. This is pretty standard and is one of the legal requirements for a social sportsbook or casino to operate in the US in 2026.
Onyx Odds has very little presence on social media for now, but I did spy a couple of promotions advertised on their Instagram – including an ad for the 5,000 free Onyx Coins welcome pack I’ve already talked about. They don’t post very regularly, but be sure to keep an eye out for other promotions.
At the time of writing, new Onyx Odds players in permitted states can claim a welcome bonus which, for most, is worth $100 in Free Picks.
This is all well and good if you’re here just to enjoy making free sports picks on NFL, NBA, and NHL games for entertainment purposes only, but it won’t give you any free Onyx Cash, sweepstakes-style coins. The first purchase promo is your best bet if you’re looking to grab some free Onyx Cash, as a 100% purchase match will get you $100 in Free Picks.
Although the Onyx Cash no deposit bonus options are a bit limited here compared to, say, sites like Rebet, it’s worth checking the site out and exploring the sports picks with your free Onyx Coins initially. And if you are looking for casino-style games, you won’t find any sweepstakes games here yet, as the site is purely aimed at social sports betting.
If Onyx Odds takes your fancy, you’ll find direct links to the site in my banners right here. Alternatively, check out my reviews of Rebet, Stake.us, or McLuck if you’re looking for something a little different.
Yup – it was 100% purchase match for up to 100 in Onyx Cash Free Picks, though this might be different from state to state. No purchases are required at Onyx Odds, though, so only take this offer up if you plan to make a purchase and it’s within your means.
No, while the site’s main landing page and general information can be accessed from a computer, their actual social sportsbook is only compatible with smartphones, tablets, and mobile devices.
Right now, no – but their mobile-friendly website seems to work fine on Safari and Chrome.

Offering a free-play social sportsbook that covers NBA, UFC and a decent selection of other sports markets, this up-and-coming social betting site is pretty cool – and there’s a ‘100% purchase match for up to 100 in Onyx Cash Free Picks’ bonus on offer for new players here, too, and you’ll be all set to explore the sports markets available at this site.
That said, you won’t be able to play at Onyx Odds if you live in AL, CO, ID, LA, MI, MT, NV, TN, or WA, due to local state restrictions.
Although Onyx Odds hasn’t really been promoting its bonus all that much since the site’s launch, you should receive the 100% purchase match bonus after making your first purchase.
I found it pain-free to claim, and I created an account using my iPhone (because the site’s sportsbook is inaccessible from a computer) and got my 100% Onyx Cash Free Picks. It’s a bit unfortunate that there’s no free Onyx Cash included in the welcome deal, but there are ways to get it for free. I didn’t go for the mail-in offer because, let’s face it, it’s gonna be a bit long-winded knowing the US Postal Service these days.
This is a big fat no – because Onyx Odds is a social betting site where you can only ever make sports picks using just-for-fun Onyx Coins, or sweepstakes-inspired Onyx Cash.
The latter can be redeemed for real-world prizes via the “Redeem Onyx Cash” tab. There is a 1x playthrough requirement on all Onyx Cash, and a minimum redemption requirement of 20 OC.
If you get the same bonus I did, the biggest bugbear is that you won’t get any free Onyx Cash unless you send in a mail-in request or make an optional Onyx Coins purchase later on.
For free-play sports picks, the offer’s a great way to check out the site and explore the sports picks. But for free sweepstakes-style coins and the chance to chase prize redemptions, it may be more difficult to get going, especially if you don’t plan to make an Onyx Coin purchase. However, as Onyx Odds is still quite new on the scene, I don’t want to dismiss it completely. If you are looking for a more established site, you may want to try Rebet or one of the other sites mentioned in my social betting comparisons.
