Onyx Odds reviews
explained, the online sweepstakes and social betting market in the US is becoming almost as crowded as the sweepstakes 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 first signed up to this site, I was given a 1,000 Onyx Coins no purchase bonus so that I could make some sports picks for fun. To my slight disappointment, I didn’t get any Onyx Cash free upon registration, which is the redeemable currency for cash prizes.
Here is a short summary of the details:
| Site: | Onyx Odds |
| Type of site: | Sweepstakes sportsbook |
| No deposit welcome offer: | 1,000 Onyx Coins FREE |
| Onyx Odds promo code: | N/A |
| Purchase promotions: | Yes ✅ |
| Mail-in request: | Yes ✅ |
| Daily reload: | No ❌ |
I can't forget the 'Spend $10, get 25 FREE Onyx Cash' first purchase bonus too. This is available to new players who have not yet made a purchase on site, and it's a great way to top up your virtual balances. Although, I must add that as Onyx Odds is a social sportsbook, no purchase is necessary, and you can access the site and sports predictions for free.

- Create a secure password

- Click to the next page

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 have to verify your ID or phone number to get the 1,000 Onyx Coins for free when you sign up. However, I recommend that you do this straight away as only verified accounts can claim the purchase promotions and other offers.
🎲 Bet for Free Before You Make a Purchase
The Onyx Coins that you get have no real-world value and can only be used to make picks for fun. To get some free Onyx Cash as a bonus, you will need to make an Onyx Coin purchase. However, before deciding if you want to spend money on the site I would use your free Onyx Coins first.
🏈 Stick to Sports You Know
If you want to make successful picks in the Onyx Odds sweepstakes, stick to sports and markets that you understand and know well. Even though you’re using virtual currency and not real money funds, you probably still want to win I imagine.
As I said in Point 2, you don’t get free Onyx Cash (SCs) with the welcome offer. The best way to get free SCs is by purchasing Onyx Coins, but don’t spend more than you can afford just to get a larger SC bonus.
As I will explain later in my bonus review, the redemption process at this sweepstakes sportsbook can be slower than most. If you’re going to bet here with Onyx Cash (SC), you need to be prepared to be patient.
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
2. Do I need an Onyx Odds bonus code?
No, as things stand right now in May 2025, you don’t need a promo code to claim this offer. However, if and when that changes, we will provide the valid code for you here in the banners on this page.
3. Is there an Onyx Odds deposit bonus?
As it is a social sportsbook and not a gambling site, you cannot deposit or withdraw funds. The closest equivalent to Onyx Odds deposit offers are the purchase promotions, which come with free Onyx Cash (SC) when you purchase bundles of Onyx Coins (GC). The best offer right now is the 'Spend $10, get 25 FREE Onyx Cash'.
4. What can I use the bonus for?
Just to be absolutely clear, this isn’t an Onyx Odds social casino bonus, it’s a sweepstakes sportsbook bonus. As a result, you can use your free coins to make social sportsbook picks at competitive odds for fun.
5. Can I win real money with the welcome bonus?
No, you can't. The sign up offer consists solely of Onyx Coins, which are non-redeemable coins with no cash value. However, the Onyx Cash that you get with your purchase promotions can be redeemed for real prizes if you play through them at least once by using them to back your sports picks. Here are more
free to play casino games that pay real money, if you want to explore more options.
Loyalty programs and other Onyx Odds sweepstakes offers
One thing you'll note when you check out he 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 1,000 Onyx Coins (GC) is a more than decent amount to explore the site. However, I would like to see a handful of Onyx Cash (SC) added to the no deposit bonus to boost it slightly.
The addition of the first purchase promotion 'Spend $10, get 25 FREE Onyx Cash' helps to bolster your virtual balance, but it should only be used if you plan to purchase Onyx Coins and it fits within your budget. All in all, Onyx Odds has a lot of potential and I could see it becoming a very popular social betting site.

Daily picks from betting experts on odds boosts and casino promos
The welcome offer at this social sportsbook online is 1,000 Onyx Coins. For clarity, these coins serve the same purposes as Gold Coins (GCs) on most other sweepstakes casinos and social betting sites. Another bonus to consider is the first purchase promo, spend $10 on Onyx Coins and receive 25 free Onyx Cash as an extra!
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 1,000 Onyx Coins straight away 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 (besides 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 them 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.
