OnyxOdds Review: Sweepstakes Sportsbook for 34+ US States
OnyxOdds (onyxodds.com) is a sweepstakes social sportsbook operated by Onyx Games LLC, launched in 2024 and headquartered in New York, NY. The platform operates under US sweepstakes law, not gaming or sports betting regulation. As of February 2026, OnyxOdds is available in 34+ US states and covers major sports leagues including NBA, NFL, NHL, and MLB. We scored it 6.4/10 across five categories.
OnyxOdds is a traditional odds-based sportsbook skin running on the sweepstakes model, as distinct from Novig US's peer-to-peer prediction market approach. Players pick outcomes at set house lines using either Onyx Coins (no prize value) or Onyx Cash (redeemable at 1 OC = $1). The house sets lines with standard sports betting margins.
OnyxOdds Welcome Bonus: 1,000 Onyx Coins Free
New players receive 1,000 Onyx Coins with no purchase required on signup. Onyx Coins are the play-only currency, no redemption value. The free welcome offers no free Onyx Cash (redeemable currency), which is a weaker free welcome than platforms like Novig US (5 NC free) or Fliff Social (which provides redeemable currency in its free welcome).
The first purchase deal is 25 Onyx Cash for $10 using code ONYX100. That's 2.5 Onyx Cash per dollar spent, or $25 in prize value for $10 invested, a 150% bonus on the cash value. For context, Novig US offers 5 NC free with no purchase; OnyxOdds' entry point requires $10 to access meaningful Onyx Cash.
First purchase value comparison (sweepstakes sportsbooks):
| Platform | Free Redeemable Currency | First Purchase Deal |
|---|---|---|
| OnyxOdds | 0 Onyx Cash | 25 OC for $10 (code ONYX100) |
| Novig US | 5 Novig Cash free | N/A (peer-to-peer model) |
| Rebet | Varies | Platform-specific |
The ONYX100 promo code is required for the first purchase deal. Without it, the standard purchase delivers fewer Onyx Cash per dollar.
OnyxOdds Sports Coverage
OnyxOdds covers NBA, NFL, NHL, MLB, and additional sports leagues. The exact sports menu depth (number of markets per game, prop bet availability, live betting) is not fully documented in available public materials as of February 2026. Standard sweepstakes sportsbook coverage includes game lines, spreads, and totals. Prop bets and same-game parlays are less consistently available across sweepstakes sportsbooks.
The 34+ state availability is the primary geographic differentiator. States where traditional sports betting is prohibited can access OnyxOdds via the sweepstakes framework.
OnyxOdds Playthrough Requirement
Onyx Cash carries a 1x playthrough requirement at -500 odds or longer before it's eligible for redemption. The odds restriction is the key detail: a player can't simply place a -10000 moneyline lock to satisfy the playthrough. The -500 ceiling means Onyx Cash must be wagered on a bet at odds no shorter than -500.
For sports bettors this is manageable, most standard game lines and spreads are priced between -150 and +300, well within the -500 ceiling. Bet on any game line at -400 or longer odds once per Onyx Cash unit, and the playthrough is satisfied.
OnyxOdds Payout Speed and Banking
OnyxOdds processes Onyx Cash redemptions via three methods: bank transfer (5-10 business days), PayPal (3-7 business days), and physical check (10-20 business days). The minimum redemption is 20 Onyx Cash ($20).
The $20 minimum is competitive, matching Novig US at the low end of the sweepstakes range. The timelines are slower. Novig US offers instant Trustly/Venmo payouts; OnyxOdds' fastest option (PayPal) takes 3-7 days. Physical check at 10-20 days is available for players without digital payment accounts.
Payout method comparison:
| Method | OnyxOdds | Novig US |
|---|---|---|
| Fastest | PayPal: 3-7 days | Trustly/Venmo: instant |
| Bank Transfer | 5-10 days | 2-3 days |
| Physical Check | 10-20 days | N/A |
| Minimum | $20 | $20 |
The physical check option is a useful fallback for players without PayPal or bank accounts, though the 10-20 day timeline is long. No mobile app is available, web browser only.
OnyxOdds VIP Program
OnyxOdds runs a VIP loyalty program with status tiers earned through Onyx Coins gameplay. Specific tier names, progression thresholds, and tier-level benefits are not detailed in available public documentation as of February 2026. Players interested in the VIP structure should check the platform's VIP section directly.
OnyxOdds Trust and Legitimacy
Onyx Games LLC is incorporated in New York, NY, one of the more legally complex states for gaming-adjacent businesses. Operating as a sweepstakes platform under NY registration adds some credibility to the operator's legal compliance posture. The platform launched in 2024 and has a developing complaint history.
No active legal proceedings against Onyx Games LLC are on record as of February 2026. The sweepstakes law framework governs the platform, not gaming regulation. Mail-in AMOE is included as required for sweepstakes legality.
OnyxOdds State Availability
OnyxOdds operates in 34+ US states under the sweepstakes framework. No specific restricted states list is published in current Terms of Service. Players should verify eligibility in their state directly on the platform before purchasing Onyx Coins.
