Today, I’ll be taking a detailed look at the latest Onyx Odds promo code – an offer that’ll potentially bag you 1,000 free-to-play Onyx Coins on sign-up.Onyx Odds Review 2025 | deadspin.com
For those of you unawares, Onyx Odds is a fresh-to-market social sportsbook that lets you bet on sports for free, and sometimes redeem cash prizes – but only once you’ve wrapped your head around the site’s two-tier coin system. In this guide, I’ll share all the juicy details about the brand’s welcome bonus, which is decent, but far from outstanding.Onyx Odds Review 2025 | deadspin.com
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 1,000 free Onyx Coins immediately. These, if you didn’t already know, are what the site calls a “freemium” product – they’re just-for-fun coins that can’t be transferred off the site or redeemed for any IRL prizes.
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. That said, I personally didn’t receive any Onyx Cash at all with the brand’s sign-up bonus.
Unlocking your free, just-for-fun Onyx Coins is a pretty simple procedure. I managed to get mine by:
Confusingly, 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 a 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 I automatically had 1,000 Onyx Coins in my balance. Frustratingly, I didn’t get any free Onyx Cash, but as the site’s available to over-18s in 41 different US states, there’s no telling whether you’ll get the same bonus I did.
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 rather-limited 1,000 free Onyx Coins start-up balance, or you’re keen to claim some free Onyx Cash, I’d suggest checking out the site’s optional purchase bundles.
Of course, only Onyx Coins can ever be bought outright. But guess what? You’ll qualify for some free Onyx Cash as a sort of bonus with every optional buy-in. Packages start from $10 for 10,000 Onyx Coins with a 10 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.
Now, this 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 in 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:
As far as I can tell, no. Of course, that’s exactly what I got, but there’s nothing in the T&Cs right now to indicate all players will get the same bonus in all states.
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 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-at 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.
I found Onyx Odds to be a bit frustrating when it comes to bonuses for existing players – but that’s not to say there aren’t any at all.
The brand’s not advertising a VIP or loyalty program, and has no obvious “Promotions” page, either, outside of the “Purchase” page I mentioned earlier, which is where you’ll find your Onyx Coins bundle options.
After digging around in their “Sweepstakes Rules”, though, I did unearth 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 100 times max.
Onyx Odds has very little presence on social media, 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, then, new Onyx Odds players in permitted states can claim a welcome bonus which, for most, is worth 5,000 free Onyx Coins.
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 probably not ideal if you were hoping to bag some free, sweepstakes-style coins.
As we’ve seen, you can opt into an Onyx Odds bonus at any time, in that it’s possible to purchase Onyx Coins and unlock free Onyx Cash as a bonus here. Failing that, though, the Onyx Cash bonus options are a bit limited here compared to, say, sites like Rebet – while you won’t find any sweepstakes casino games up for grabs here yet, either.
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 worth 1,000 free Onyx Coins when I claimed it, though this might be different from state to state.
Nope. 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 1,000 free Onyx Coins bonus on offer for new players here, too.
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, and the bonus certainly has its shortcomings.
Onyx Odds hasn’t really been promoting its bonus all that much since the site’s launch, so there’s no telling whether you’ll get the same 1,000 free Onyx Coins bonus that I did in your state.
If you are offered the same deal, I found it pain-free to claim, though. I created an account using my iPhone (because the site’s sportsbook is inaccessible from a computer, remember?) and got my free 1,000 Onyx Coins quickly. It kinda sucked that I didn’t get any free Onyx Cash, though.
Shortly afterwards, I purchased a $25 Onyx Coins package, which got me 25,000 Onyx Coins and 25 free Onyx Cash. 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. However, there’s a 1x playthrough requirement affecting 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.
It depends on your intentions, really. For free-play sports picks, the offer’s a-okay. But for free sweepstakes-style coins and the chance to chase prize redemptions, you might be better off with Rebet, or one of the other sites mentioned in my social betting comparisons.
