What Is Onyx Odds?

Onyx Odds is a social sportsbook and sweepstakes gaming platform operated by Onyx Games LLC out of New York. It launched in 2024 and has grown quickly by offering a clean, mobile-first experience focused on the major U.S. leagues.

The platform runs on a dual-currency model that lets players:

Make sports picks on NFL, NBA, MLB, NHL, college football, college basketball, UFC, and more
Compete for VIP tier progression and loyalty rewards
Redeem prize winnings in real cash via ACH

Because Onyx Odds does not accept real-money wagers, it operates under sweepstakes promotional law rather than state sports-betting regulation. That’s what lets it function in states like Texas, California, Georgia, and Florida, places where traditional sportsbooks still aren’t legal.

Onyx Coins vs. Onyx Cash — The Dual-Currency System

Currency	Purpose	Redeemable For Real Money?
Onyx Coins	Fun / social play currency	❌ No
Onyx Cash	Sweepstakes currency	✅ Yes (after 1x playthrough)

Onyx Coins

Onyx Coins are the entertainment currency. You get them free at signup, through daily rewards, and inside purchased bundles. Use them to practice, test parlays, or run prop models without risk. Onyx Coins cannot be redeemed for prizes.

Onyx Cash

Onyx Cash is the prize-eligible currency. You cannot buy it directly — you earn it through:

The first-purchase match (the CLEATZ bonus)
Bundle promos
Daily login rewards
Social media contests run on @OnyxOdds
Free mail-in entries (AMOE) per the sweepstakes rules

One Onyx Cash equals $1 USD in redemption value. The minimum redemption is 20 Onyx Cash ($20), paid via ACH.

For a full breakdown of how sweepstakes currencies compare to real-money prediction markets, see our best prediction market apps guide.

Onyx Odds State Availability & Eligibility

Onyx Odds is available in roughly 40 U.S. states. State laws shift, so treat this as a guide and re-check at signup.

✅ Available in (partial list): AK, AZ, AR, DE, FL, GA, HI, IL, IN, IA, KS, KY, ME, MA, MN, MS, MO, NE, NH, NM, NC, ND, OH, OK, OR, PA, RI, SC, SD, TX, UT, VT, VA, DC, WI, WY

CLEATZ tip: If you’re in one of the ~10 states where real-money online sportsbooks are still off-limits, Texas, California, Georgia, Onyx Odds is one of the cleanest ways to get a real sportsbook experience without running a VPN or breaking a rule.

Prize Redemption & Cashouts

Feature	Detail
Minimum redemption	20 Onyx Cash
Exchange rate	1 Onyx Cash = $1 USD
Payment method	ACH bank transfer
Processing time	Up to 7 business days
Playthrough requirement	1x on Onyx Cash
Redemption fees	None stated

Compared to a lot of sweepstakes sites that lock you into 3x or higher playthrough, Onyx Odds’ 1x requirement is player-friendly. If you win 30 Onyx Cash on a pick, you’ve technically cleared playthrough on those exact units the moment the pick settles.

Onyx Odds KYC & Identity Verification

Identity verification is handled by Socure, a major U.S. identity-verification provider also used by several federally regulated fintech platforms.

What you’ll submit at KYC:

Government-issued photo ID (driver’s license or passport)
Proof of address (utility bill or bank statement)
Live selfie that matches the ID photo
Basic profile info (full name, DOB, address)

When: KYC is triggered the first time you try to purchase coins or redeem Onyx Cash. You can sign up and play with the free Onyx Coins without completing KYC, but you’ll need to finish it before any prize cashout.

Playthrough Requirements

1x playthrough on Onyx Cash before it becomes redeemable
Minimum 20 Onyx Cash to submit a redemption
Onyx Cash and Onyx Coins expire after 60 days of account inactivity — log in at least every 60 days to preserve balances

A $10 first purchase unlocking 100 Onyx Cash, plus the standard Onyx Coins in the bundle, means you can play reasonable volume before needing to re-up. That’s a meaningfully better value than most first-purchase matches in the sweepstakes category.

Sports & Markets Available on Onyx Odds

Onyx Odds covers the major U.S. leagues and a modest but usable selection of bet types:

Leagues: NFL, NBA, MLB, NHL, NCAAF, NCAAB, UFC/MMA, soccer (EPL, La Liga, MLS, Champions League), tennis, golf, NASCAR

Bet types:

Moneyline
Point spread (with alt lines)
Totals (full game + alt lines)
First-half / second-half lines
Player props (passing yards, rushing yards, receiving yards, points, rebounds, assists, etc.)
Team totals
Parlays

The prop menu is thinner than Fliff or Rebet. Onyx runs maybe 15–25 markets per NBA game, compared to 100+ on some competitors. The lines themselves are sharp, though. Typical -110 or -108/-112 juice, not the -115 you see on some social books.

If you’re running prop models, pair this page with Cleatz’s NBA player props and NFL props tools to pressure-test picks for free.

Onyx Odds vs. Rebet vs. Fliff vs. Stake.us

Feature	Onyx Odds	Rebet	Fliff	Stake.us
Welcome match	100% up to 100 Onyx Cash	100% up to $100	$1.50 Fliff Cash + coins	$25 Stake Cash + coins
Min. redemption	20 Onyx Cash	20 Rebet Cash	$50 Fliff Cash	$50 Stake Cash
Playthrough	1x	1x	1x	1x
Sports markets	Modest	Wide (60+ leagues)	Wide	Narrow (casino-heavy)
Mobile app	Mobile web only	iOS + Android	iOS + Android	Mobile web
Juice (standard)	-110	-110	-115	-110
Social features	Minimal	Strong (feeds/community)	Medium	Minimal
KYC provider	Socure	Plaid	Veriff	SumSub

TLDR: Rebet wins on breadth and social. Fliff wins on app polish. Stake.us wins on casino pairing. Onyx Odds wins on sharp lines and the friendliest redemption floor in the category ($20 vs. $50 at Fliff/Stake).

Ongoing Promos For Existing Onyx Odds Players

Onyx Odds doesn’t run a huge ongoing promotions page, the action lives elsewhere:

Daily login rewards — free Onyx Coins and occasional Onyx Cash
Bundle purchase promos — inflated Onyx Cash boosts on specific Onyx Coins packages
Parlay Picks & boosted odds — shown in-app on select live games
Social contests — @OnyxOdds on X and Instagram runs jackpot-style giveaways (e.g., first-touchdown and first-basket jackpots)
VIP program — loyalty points from picks unlock tiered perks. Spending $2,000+ in your first 30 days fast-tracks VIP status.
Mail-in AMOE — handwritten requests to Onyx Games LLC, 169 Madison Ave. STE 11498, New York, NY 10016, get 5 free Onyx Cash per submission, up to 100 per participant.

Is Onyx Odds Legit & Safe?

Yes.

Onyx Odds operates under U.S. sweepstakes promotional gaming law. The legal structure removes the “consideration” element of a traditional wager — you cannot directly purchase Onyx Cash, and free alternate methods of entry exist — which is what lets Onyx run in the 40 states where it’s available.

Identity and anti-fraud verification is handled by Socure, the same ID provider used by major U.S. fintechs. Payments move via ACH through standard banking rails. The company has a clean operating track record since launch in 2024.

What Onyx Odds is not: It is not a licensed real-money sportsbook. You do not “deposit,” you do not “withdraw bets,” and Onyx Coins themselves have no redemption value. Understanding that distinction is the single most important thing a new player can do.
