Onyx Odds Bonus: How To Claim Their Latest Bonus in 2025

We tried out the Onyx Odds bonus to see if it works the way it’s advertised. And no, not that Onix. This one’s not a rock snake from Pokémon, it’s a sweepstakes-style sportsbook with a generous sign-up offer.

At Onyx, you’re using virtual currencies to make picks, and if they hit, you can redeem one of them for prizes. This guide looks into what you get with the Onyx Odds promo code, how to avoid messing up your bonus, where it’s available, and what to expect when it comes to redemptions. Let’s get into it.

About Onyx Odds

Join Onyx Odds and claim top sports promos

Bet on your favorite teams with Onyx Odds

Onyx Odds is a sweepstakes-style sportsbook where you make sports predictions using virtual currencies instead of real money. It’s not a typical betting site, everything runs on either Onyx Coins (for fun) or Onyx Cash. The latter can be redeemed for real prizes once the relevant requirements are met. As mentioned in our Onyx Odds guide, the main focus here is single-game picks, not parlays or casino-style games.

The site is mobile-first and built for users in states where traditional sports betting isn’t legal. It runs KYC checks through Socure before you can redeem anything.

What the Onyx Odds sign up bonus gives you

If you’re signing up for the first time, Onyx Odds offers a 100% match up to 100 in bonus picks. To trigger it, access Onyx Odds via our link, and find the promo code on the homepage code during sign-up. Here’s a quick overview of the sign up bonus:

The matched bonus is added to your Onyx Cash balance, which is the part of your wallet used for prediction games. Bonus picks aren’t just for show, you can actually use them on real sporting outcomes. But they do land with some rules attached.

Here’s what to know:

• You need to use the bonus picks once before doing anything else with them.
• You have to make a prediction at odds of −500 or longer. That means things like −200 or +150 are fine, but −700 won’t count.
• Avoid “opposite selections” (picking both sides of a line). That disqualifies your picks.
• Bonus picks can’t be used on mini-games like Onyx Blackjack or anything involving Cash Out.

As long as you play by the rules, the bonus is simple to activate and use.

What are bonus picks?

When Onyx talks about bonus picks, they’re really talking about a specific kind of virtual currency you can use to make sports predictions called Onyx Cash, also called Sweepstakes Cash in the rules. These picks aren’t just tokens or entries, they act like real social bets on real games.

Bonus picks are credited to your Onyx Cash wallet when you claim a promo. They’re not regular Onyx Coins (which are just for playing around). Instead, bonus picks are tied to the sweepstakes side of the site, which means they can be used for prize redemption via Onyx Cash, but only after you’ve used them once on a prediction at odds of −500 or longer. So when you see “100 bonus picks” as part of a signup offer, that’s 100 Onyx Cash you can use to make eligible picks on upcoming games, not just free spins or tokens.

Pros and cons of the Onyx Odds sportsbook

Pros and cons

• 100% match up to 100 in bonus picks for new users
• Simple 1× playthrough at −500 or longer odds
• Bonus credited as Onyx Cash, usable on real predictions

• Opposite selections void bonus eligibility

How to claim the Onyx Odds bonus

Let’s walk through it from the start:

1. Step 1: Sign up through our link - Use our link to go straight to Onyx Odds. From there, you can find the promo code on the website or T&C’s. You’ll still want to double-check that it’s showing during sign-up just in case.
2. Step 2: Complete KYC - You won’t be able to redeem prizes or even make optional Onyx Coin purchases until you complete KYC. Onyx uses Socure, which means you’ll likely need to submit a government ID, a live selfie, and proof of address.
3. Step 3: Bonus picks show up in Onyx Cash - Once you’re verified and signed in, your matched amount (up to 100) lands in your Onyx Cash balance. That’s what you’ll use to make your first predictions.
4. Step 4: Make your first pick (−500 or longer) - You’ll need to use your Onyx Cash on a pick with odds of −500 or longer. A −150 single-leg prediction on a popular market works fine here. Opposite selections or hedging picks (say, picking both sides of a line) void your eligibility.
Step 5: Redeem your prizes - If your pick hits and you’ve played through your Onyx Cash on an eligible selection, you’ll be able to request a Onyx Odds prize redemption. This isn’t instant, Onyx says processing can take up to 30 days, especially if the amount is large. You’re only allowed to make one Onyx Cash redemption request every five days, and there are limits in place. Depending on your state, the caps might be stricter. You’ll need to have at least 20 eligible Onyx Cash before you can request a prize redemption.[/step-by-step-list-item]

Tips for getting the most from bonus picks

Bonus picks are great if you use them right, but there are a few easy ways to mess them up. These top tips for Onyx Odds are based on what we ran into while using the site, and what helped us along the way. If you want the best shot at making your bonus count, these are worth keeping in mind.

Bonus not showing? Try these

If your bonus picks didn’t land in your account, don’t panic. It’s usually something simple. These are the most common things we’ve seen go wrong, and what you can do to fix it before contacting support.

Make sure you used the Onyx promo code during sign-up

Not every Onyx Odds promotion will require a promo code. But if you see a code mentioned on their website, you’ll need to use it to claim the bonus. If you skipped it, closed the tab halfway through, or signed up with a different link, the bonus won’t apply. Go back and check your registration email. If the code isn’t mentioned, it likely didn’t go through.

Check if you're in a restricted state

Onyx Odds isn’t available everywhere, and if you're in one of the blocked states, the bonus won’t apply, no matter what. As of now, you can’t sign up or claim the bonus if you're located in Alabama, Colorado, Connecticut, Idaho, Louisiana, Maryland, Michigan, Montana, Nevada, New Jersey, New York, Tennessee, Washington, or West Virginia. The site checks your location during sign-up, so even if the promo code is entered correctly, the bonus won’t trigger if you’re in one of these states.

Complete KYC

Your account isn’t fully active until you pass identity verification. Onyx uses a third-party service called Socure, and they’ll ask for a government ID, a selfie, and something with your address on it. If you skipped this part during sign-up, your bonus might be pending in the background but won’t unlock until you finish verification.

Avoid using ineligible games

We learned this the hard way. Using bonus picks on blackjack or triggering a “Cash Out” means those picks don’t count. Even if you win. Make sure you’re using your bonus on straight predictions (like point spreads or totals) and avoiding anything outside the social sportsbook section.

Contact support if nothing else works

If you’ve checked everything above and still don’t see your bonus, it’s time to message Onyx support. You can do it in-app, and they usually reply within a few hours. Just be ready with your sign-up date, promo code, and what pick you tried using. It makes the process easier for everyone.

No Pokéball needed for this Onyx

We’re not talking about Brock’s giant rock snake from Pokémon here. This Onyx is a top social sportsbook, and while it won’t evolve into Steelix, it does come with a solid sign-up bonus that’s easy enough to use if you follow the rules. If you’re into social sports picks and live in an eligible state, the welcome bonus is really easy to use.

The only real catch is following the rules. You need to make sure that you use the right odds (−500 or longer), don’t mess with blackjack or Cash Out, and make sure you’re verified before trying to redeem anything. As long as you’re not rushing through it, the offer works like it says it will.

Want to try it for yourself? Sign up via our link on our homepage to access the bonus, and search the website for the correct promo code. Sometimes the code will even apply automatically when you hit the sign-up page. Just keep an eye on your balance so it doesn’t expire, and always check what’s live in-app, since bonus amounts and promos can change.
