Onyx Odds has a responsive and beautiful mobile website, but its competitive odds are what make it a top sweepstakes betting site. As more individuals register on the site, there is an intense search for an Onyx Odds promo code.

The good news is you don’t need a promo code to tap into the various promotions the operator offers. Signing up on the site rewards you with 1,000 Onyx Coins, which you can use to wager on 20+ sports markets, including Football, Soccer, Baseball, Basketball, and UFC. Read on as I breakdown the promo terms and other offers here.

What is the Onyx Odds promo code?

With so many bonuses from the operator, it’s a good thing you don’t need an Onyx Odds bonus code to get them. This saves you time when betting on the site, letting you get in on the action as quickly as possible.

The operator only requires potential bettors to sign up for an account, which is necessary for its identity and location verification. Creating an account is also the only step you need to get the Onyx Odds sign up offer. I was able to do this in less than 5 minutes, which is fair.

Your welcome bonus at the site is a 1,000 Onyx Coins bonus, which you’ll find in your account once you log in for the first time.

Do you get a no deposit bonus from the operator?

An Onyx Odds no deposit bonus doesn’t exist, and for a good reason. Since the site functions as a social sports betting platform, it does not accept any form of real money deposits or wagers from its bettors.

How do you use the Onyx Odds promo code offer?

If you don’t already know, you don’t need to play on sweepstakes casinos with real money. Instead, you’re placing social bets with virtual currencies that you receive from the operator.

On regular sweepstakes sports betting sites, the virtual currencies you use are known as Gold Coins (GC) and Sweeps Coins (SC). However, Onyx Odds has specific names for the virtual currencies, letting you play with its Onyx Coins and Onyx Cash.

Each type of virtual coin has its specific use that you must know about before betting on the site. Read on as I show you how they work.

Onyx Coins

The Onyx Coins function in the same manner as the GC you find on other sweepstakes sports betting sites. You can only use them for recreational play, where your winnings have no value.

There are numerous options to find Onyx Coins, and these typically involve one of the many promotions offered by the operator. Another option is to visit the Onyx Odds store, where you can find optional Onyx Coins packages to purchase. While I like the idea of purchases, I prefer claiming free Onyx Coins by making correct predictions.

Onyx Cash

When it’s time to get serious at Onyx Odds, you’ll want to play with your Onyx Cash. This virtual currency is only available through bonuses, and you don’t find it on sale at the store. You also receive more Onyx Cash from winning wagers, but this has a more significant purpose.

The limited supply of Onyx Cash is because the winnings you accumulate when wagering with it are redeemable. At Onyx Odds, you can redeem your Onyx Cash winnings for a prize once you meet certain conditions, like the playthrough requirement and minimum redeemable Onyx Cash.

Claiming the Onyx Odds bonus – A quick guide for you

My time at the site started with me testing its service using the Onyx Odds welcome offer. To get to this point, you’ll need an account, which can be set up within five minutes.

Onyx Odds is a mobile-only sweepstakes betting site, so you’ll need to complete the process using a Safari or Chrome browser, since there is no dedicated app. Once you have your device ready, just follow these steps:

  1. Tap the Onyx Odds banner to redirect to the official website.
  2. Select the Sign Up Now option on your screen.
  3. Enter your email, username, and password.
  4. There is a field for an Onyx Odds promo code, but you don’t need one.
  5. Accept the terms and conditions.
  6. Tap on Create Account to proceed.
  7. You can complete your identity verification or skip for now.
  8. Log in for your welcome bonus.

Just like the Scarlet Sands promo code, an Onyx Odds code isn’t available. This was not a problem since it gave me instant access to all promotions at the site.

Terms and conditions of the Onyx Odds bonuses

While Onyx Odds gives you free virtual currencies to play games and redeem winnings, there are guidelines you must follow. These are available as terms and conditions, and failing to stick to them can void your winnings.

Some of the most important conditions I found during my Onyx Odds review include those I’ve highlighted here.

Ongoing Onyx Odds promotions for existing bettors

Onyx Odds has been trying to get the right balance for its ongoing promotions, so you’ll often find some time-limited offers on the site. In addition to these, you also have access to some permanent Onyx Odds promotions. Here are some of the options I came across.

BonusWhat you get
Welcome bonus1,000 Onyx Coins
Mail-in bonus5 Onyx Cash
First purchase bonusSpend $10 and get 100 bonus picks
Social media promotionsVary
Refer a friend bonus25 bonus picks for you, and 100 bonus picks for your friend

📬 Mail-in Bonus

Claiming the mail-in bonus is one of the top ways to get free virtual currencies at Onyx Odds, and I recommend you try it. If you complete the necessary steps for this bonus, you’ll get 5 Onyx Cash per request. This is around the highest amount you’ll get for a mail-in bonus, so if you snooze, you lose.

There are many important steps to take if you decide to claim the offer, and Onyx Odds highlights each step on the Sweepstakes Rules page.

You can only send 100 requests per sweepstakes entry period, which is from the first to the last day of every month.

đź›’ First Purchase Bonus

The first purchase bonus applies when you make an optional Onyx Coins purchase at the site. This is a one-time offer, and you receive 100 bonus picks when you spend $10. Purchases are not compulsory, but they tend to come in handy for me because I make lots of predictions.

📱 Social Media Promotions

If you spend lots of time on social media sites like Instagram and X, following Onyx Odds on these platforms is one way to get bonuses. These offers are exclusive to social media, but you may find some banners on the site that redirect you to the relevant page.

Many of the social media offers are giveaways, and you’ll need to follow specific steps to be eligible for the bonus. However, you won’t need an Onyx Odds promo code for most. I’ve seen a 10,000 Onyx Cash giveaway from the operator for hitting 10,000 followers on X, so another giveaway at 15k or 20k followers isn’t out of the question.

👥 Refer a Friend Bonus

One of the top promotions you’ll find on sweepstakes sites like Golden Hearts games is the Refer a Friend bonus, and Onyx Odds has this offer. Unlike many operators that reward you with free GC or SC for letting your friend know about the site, Onyx Odds gives you bonus picks.

The Onyx Odds Refer a Friend bonus rewards your account with 25 bonus picks when you get a friend to register on the site. Instead of an Onyx Odd bonus code, all you need to do is share your personal link, which you can copy from the profile page of your account.

Any friend you invite must make their first optional Onyx Coins purchase of $10 or more for the referral bonus to count. As a reward, your friend also receives 100 in bonus picks from the brand.

Conclusion – Should you keep hunting for Onyx Odds promo codes?

No, you don’t need to search for Onyx Odds promo codes. These codes aren’t available right now, and when a functional code appears, I’ll always post an update about it. Onyx Odds is one of the top sweepstakes sports betting sites available at the moment, and you’ll have access to competitive odds from popular sports in the US. To start placing social wagers, click any of the banners on this site to register and get a 1,000 Onyx Coins welcome bonus.
