Thunder @ Spurs Predictions, Tonight 9:30 PM ET

• Line: Spurs -2.5, moneyline Spurs -120 / Thunder +110, total about 228.5-231.5.
• Market view: The moneyline implies roughly 54% Spurs and 48% Thunder, including the book’s margin.
• Head-to-head: The Spurs won 4 of 5 regular-season meetings last year and beat OKC 4-3 in the Western Conference Finals.
• Before betting: Check injury news close to tip-off, since Isaiah Hartenstein was day-to-day. Also compare the total across books, because the sources disagree on it.

How the Onyx Odds App Plays

Onyx Odds covers major markets, including NFL, NBA, college football, college basketball, MLB, and NHL, with props and specials that rotate based on the daily slate. Coins mode is for free play, while Cash mode is where real-money offers apply.

A social feature lets users view other players’ picks and choose to follow or fade them, useful for anyone who wants a second opinion before betting. Minigames won’t replace the core sportsbook experience, but they give users a reason to open the app even on days without major games.

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.

Onyx Odds Legal States

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.

Onyx Odds Last Word

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.
