What is Onyx Odds?
Onyx launched out of New York in 2024, and it’s not a licensed sportsbook in the traditional sense, it runs on the sweepstakes model, which is why it’s live in 40 states instead of the dozen or so where you’d find a DraftKings or FanDuel. You play with two currencies: Onyx Coins for the free-to-play side, and Onyx Cash, which is the promotional currency tied to offers like this one and what you’d eventually redeem for real prizes once you clear the play-through.
Founder Leul Dadi has talked about wanting people to stick around, not just sign up once and vanish. You can see it in the app itself, a social feed, minigames between slates, more market depth than you’d expect this early. Onyx also teamed up with Polymarket, so there’s some exchange-style prediction market stuff mixed into what’s otherwise a normal picks app.
How the Onyx Odds App Plays
Markets cover the usual suspects, NFL, NBA, college football and basketball, MLB, NHL, with props and specials rotating in depending on the slate. Coins are for fun, Cash is where the money offers live. There’s a social layer where you can see what other users are backing and either ride with it or fade it, which is a nice touch if you’re the type who likes a second opinion before locking in a pick. The minigames aren’t going to replace the sportsbook side of things, but they’re a reasonable reason to open the app on an off day.
Onyx Odds Refer-a-Friend Bonus Code MRG
Onyx also runs a referral program alongside the MRG sign-up offer. Share your unique referral link, and once a friend signs up and completes an optional $10 Onyx Coin bundle purchase, Onyx credits you with 25 free picks. Worth mentioning to whoever you invite: that $10 purchase is optional on their end, but it’s what triggers your referral bonus, and it also tops up their own balance so they’ve got something to play with right away.
Where It’s Legal
Onyx covers 40 states plus DC. It’s not available in Alabama, Colorado, Idaho, Louisiana, Michigan, Montana, Nevada, Tennessee, or Washington — mostly states where sweepstakes-model platforms have run into friction one way or another. Check your state before you sign up, since coverage has shifted before and could again.
The Good and the Not-So-Good
This is one of the easier bonuses we’ve written up — spend $10, get credited right away, nothing else to jump through. The Payward money behind it also means Onyx isn’t as thinly capitalized as a lot of sweepstakes books this size, and the markets go deeper than you’d guess for a 2024 launch.
Still a sweepstakes product though, so don’t go in expecting a straight cash deposit like you’d get at a licensed book. Nine states can’t use it, a couple of them fairly big. And it just hasn’t been around long enough to have the track record an older operator has.
