Sweepstakes sportsbooks like Onyx Odds are one of the best ways to make sports predictions for free. I recently sampled this social sportsbook's offerings to see if it's a safe and legit place for social sports fans.
My Onyx Odds review covers every critical aspect of the sportsbook, including the welcome bonus for new members of 100% purchase match for 100 free picks. I'll also explore the available customer support channels and, most importantly, the available sports markets. Dig in to find out what I discovered.
Onyx Odds uses two virtual currencies — Onyx Coins and Onyx Cash — which work together to let players enjoy sports picks and sweepstakes games. The platform recently updated its welcome offer, giving new users a better way to get started.
Starting this October, new players will get a 100% match on their first purchase, up to 100 Onyx Cash Free Picks. This replaces the old sign-up deal and is now the main offer for anyone joining Onyx Odds. To claim it, simply make your first purchase, and the site automatically adds the matched amount to your balance in Onyx Cash Free Picks.
What makes this offer appealing is how simple it is. There’s no promo code or complicated steps — just make your first buy and enjoy the extra picks. It’s not the largest bonus out there, but it’s practical and gives you more room to play around with different sports predictions.
Besides the welcome deal, Onyx Odds also includes other ways to earn rewards, like free play bonuses, mail-in offers, and loyalty perks. During my time on the site, I found it easy to explore without any pressure to spend, which keeps things fair and fun.
All in all, the current offer fits the platform well — it’s straightforward, easy to use, and a solid introduction for anyone new to social sports gaming.
Players over the age of 18 can sign up at Onyx Odds from more than 40 US states. However, the social sportsbook doesn’t accept players from a few states due to local state restrictions. Check the table below to see if Onyx Odds is available in your location.

Onyx Odds is not a sweepstakes casino, so rather than games, the entire homepage is dedicated to sports markets and odds. I also liked that there were no unnecessary banners clogging up the page.
My Onyx Odds rating for the site’s design is pretty high, as if you’re like me and not a fan of sites with really colorful themes, you’ll appreciate the clean color palette at Onyx. The entire website is black with occasional highlights of violet and blue, giving it a classy and modern look.
The website is also very responsive and loads the sports up quickly. Furthermore, the Onyx Odds site is optimized for various devices, giving you plenty of scope to enjoy its features wherever you may be.
I didn’t find a mobile app during this Onyx Odds review; however, this is not unusual for a sweepstakes site. All my gameplay was done via the mobile site, and given how simple the site is, I didn’t encounter any issues exploring it on my device. It’s mobile-friendly and adapts quickly to your screen size, perfect for placing sports predictions on the move.
Every feature available on the desktop site is also available on mobile. You’ll have a seamless experience navigating the available sports on your phone since they’re neatly sorted and displayed across the top of the homepage.
Sweepstakes sites are generally not big on robust payment options because initial purchases are optional, but most social sportsbooks I’ve used offer at least two different methods. This is true for Onyx Odds, too, and they currently offer bank transfer, Apple Pay, credit card, and Skrill as options for making a purchase of Onyx Coins. The number of payment options here is definitely a highlight.
One area where I agree with other Onyx Odds reviews is that the minimum Onyx Cash redemption requirement is lower than the industry average. You only need a minimum of 20 Onyx Cash won through social sports betting to qualify for redemption, so this feels relatively achievable.
There is only one way to contact customer support at the Onyx Odds sweepstakes sportsbook, and that is by email. The support team is helpful and professional, but it still takes a few hours on average to get a response using this channel. Furthermore, the site has a small but helpful FAQ section on the main homepage, answering some key questions.
The email address isn’t displayed on the site, but you can find it by navigating to your Account page in the bottom menu. You’ll see a Contact Us button there, and once you click it, you’ll be taken to the email address where you can start typing your query immediately. All things considered, the absence of live chat support at Onyx Odds is quite noticeable, but hopefully something that will be addressed in the future as the site evolves.

Sweepstakes sites don’t need licenses to operate, but one thing you want to check is the site’s security and safety, especially when you are entering personal details and potentially payment info. Onyx Odds has confirmed they do employ security protocols to protect players and safeguard player data, which I found reassuring. There’s also a detailed privacy policy on their site, along with the terms of use.
Another reassurance I found on the site was its dedication to responsible gaming, which includes providing many tools and accepting only players of legal age. Furthermore, Onyx Odds adheres to US sweepstakes gaming laws.
I didn’t expect to find a VIP or loyalty program during my Onyx Odds test, as the social sportsbook is relatively new. And although there is no dedicated promotions section on the site, don’t let this deter you, as Onyx actively engages players and rewards them with a bespoke VIP program offering tailored perks and benefits.
Onyx Odds also has a number of social channels to follow, including X (formerly Twitter), Instagram, and Facebook, and I think it would be worth checking them out to keep up with the latest promotions and offers.
Onyx Odds is a sweepstakes sportsbook that provides social betting opportunities to sports lovers. The site works by featuring a social sportsbook interface where players can make sports predictions using two virtual currencies rather than real money.
Yes, Onyx Odds is legal in most of the United States because it operates using a sweepstakes model rather than as a traditional sportsbook. However, you will need to check if it is available in your state, as it’s not accessible from everywhere in the US.
To get started, visit the official Onyx Odds website or click on one of their banners on this page, and follow the prompts to create an account. After registration, you will receive a welcome bonus in the form of a first purchase promo – a 100% purchase match worth up to 100 in Onyx Cash Free Picks, and this can really help boost your virtual currency on the site if you plan to make a purchase.
Onyx Odds doesn’t award prizes directly. Instead, you can make social sports bets using the Onyx Cash currency, and when you have won enough, you can redeem them for alternative prizes via the ‘Cashier’ page on the Onyx Odds site.
No, Onyx Odds does not offer casino-style games. The sweepstakes site covers popular sports events, allowing you to make social sports predictions using virtual currencies called Onyx Coins and Onyx Cash instead of real money.
This Onyx Odds review 2026 includes the most up-to-date information about the social sportsbook. Onyx Odds stands out for its comprehensive sports markets, offering players numerous options for making sports predictions.
The welcome offer that gives you the chance to take advantage of the 100% purchase match for up to 100 in Onyx Cash Free Picks after making your optional first purchase deal is a good start. The 100% purchase match is a great way to boost your virtual balance.
Although customer service options are limited right now, I’m hopeful for some changes to be made in the near future, and you can still enjoy the social sportsbook’s offerings in the meantime.

One of the first things I checked during my Onyx Odds review was the quality of the sports and the robustness of the available social betting markets. The sweepstakes sportsbook covers many sports, including the NFL, NBA, NCAAF, NCAAB, NHL, UFC, and Tennis. I could view most of the available games and events on the homepage at a glance.
If you want to see all the markets under any specific sport, just locate the sport on the ribbon above the general display and tap on it. Each sport typically covers five to ten markets, so you’ve got plenty of options for your predictions. Additionally, you can make predictions on a few live games on this social sportsbook, which gave it good ratings in many Onyx Odds reviews. The live button is on the top ribbon as well.
As a relatively new social sportsbook, Onyx Odds has yet to add any specific community features to its site. However, as this is usually a big thing for players, I hope that in the future they will add a chat feature, some contests or tournaments, and possibly an opportunity to engage in a direct challenge with a friend.
Sweepstakes sites are distinguished from real money sites by their use of virtual currencies. Although most brands use Gold Coins and Sweepstakes Coins, that’s not the situation at the Onyx Odds sweepstakes sportsbook. Here, gameplay tokens are called Onyx Coins and Onyx Cash.
Onyx Coins are the Gold Coin equivalent. It’s used for fun-only social betting and can be used to place sports predictions for fun as well. Onyx Odds will give you a steady supply of Onyx Coins through bonuses and promotions, but if you run out, you can opt for the optional first coin package purchase. And right now, you can get hold of a 100% purchase match for up to 100 in Onyx Cash Free Picks after making one.
Whilst we’re talking about Onyx Cash, this is the equivalent of the Sweepstakes Coins promotional currency at this social sportsbook. When I signed up, whilst I didn’t receive any Onyx Cash as part of my welcome bonus package, I could get hold of this for free in other ways, though, such as the first purchase promo mentioned above. Following sweepstakes rules, you cannot purchase Onyx Cash directly.
If you’re seeking a social betting site that covers top sports, has decent markets, and competitive odds, then Onyx Odds is a great choice. The welcome bonus here gets your social betting journey started, and although the site is lacking in a couple of sections, it encourages safe gaming and abides by sweepstakes rules, making it a solid site to place sports predictions.
