Onyx Odds Sign-Up Bonus: 100 In Bonus Picks + Coins
Most write-ups of the Onyx Odds sign-up bonus stop at the headline number, and the headline number is the least useful part of it. Onyx Odds is a sweepstakes social sportsbook, where you make player-prop-style predictions with virtual currency instead of wagering real money on a book, and its welcome deal is really two separate things stapled together. Just registering hands you 1,000 Onyx Coins for free, no purchase required. Spend $10 on your first purchase with code OS100 and Onyx credits you up to 100 in Bonus Picks on top of that. The part worth reading past the headline is which of those two ever turns back into a prize, and the one number that decides it is a number Onyx doesn't publish anywhere you can find before you sign up.
Hold onto that missing number, because it is the whole reason this offer is worth understanding rather than just claiming on reflex. Get the two pieces straight, know what it takes to cash the redeemable one out, and the sign-up bonus stops being a novelty and becomes a low-cost way to practice pick selection with real prizes on the line.
In Summary
- The Sign-Up Bonus Has Two Parts. Registering unlocks 1,000 Onyx Coins for free social play, no purchase necessary. Your first $10 purchase with code OS100 then gets you up to 100 in Bonus Picks (shown in-app as "Up to 100 in Games Cash on your first purchase"). New players only; subject to terms; confirm the live offer in-app before you buy.
- Only One Part Can Pay Out. Onyx Coins are for-fun and carry no cash value. Games Cash, the redeemable currency awarded as Bonus Picks, is the side you can redeem for prizes. Your 100 in Bonus Picks lands as Games Cash.
- What Onyx Odds Is: a sweepstakes social sportsbook, so there is no real-money wagering. That model is why its state map differs from a real-money book's (Onyx still excludes certain states under its rules), and why a bonus balance has to clear a playthrough before it becomes a prize.
- The Catch Nobody Prints: turning Games Cash into a payout means clearing a playthrough and Onyx's minimum redemption amount, and Onyx does not publish that redemption number. Any "20-coin" floor you see quoted comes from third-party sites, not Onyx.
- Free To Play, 18+, Not Everywhere. No purchase is necessary, you must be 18 or older, and the sweepstakes is excluded in 16 states (listed below). The signup flow is the final word for your state.
What The Onyx Odds Sign-Up Bonus Actually Includes
Start with the free half, because it is the part most rundowns skip past on the way to the bigger number. The moment you finish registration, before you have spent a cent, Onyx drops 1,000 Onyx Coins into your account for social play. That is the no-purchase hook, and it exists because a sweepstakes has to offer a free way in. It lets you open a market, build a slip, and feel out how Onyx's more-or-less-on-a-player-line format works before deciding whether to buy anything at all.

The second half is the first-purchase piece. Spend $10 on your first Onyx Coin purchase with code OS100, and Onyx credits you up to 100 in Bonus Picks, which the app frames as "Up to 100 in Games Cash on your first purchase." Sign up through our link with OS100 attached:

| Detail | What to know |
|---|---|
| Registration Bonus | 1,000 Onyx Coins for free social play, before any purchase |
| First-Purchase Match | Up to 100 in Bonus Picks (Games Cash) for a $10 first purchase with code OS100 |
| In-App Wording | "Up to 100 in Games Cash on your first purchase" |
| Who Qualifies | New players only, 18+, in an eligible state |
| The Honest Catch | The 100 arrives as Games Cash and must clear a playthrough and a redemption minimum before it can leave |
The row that decides everything is the last one. The 100 is not cash you withdraw the second you buy in; it is a stack of the redeemable currency you make picks with, and it becomes a prize only after it clears two gates most people never read about until they try to cash out. Which is exactly where a lot of first-timers get tripped up, because the two currencies do very different things.
Free Coins Vs. Bonus Picks: Which Part Can Actually Pay
This is the split to internalize before you claim anything, because the sign-up bonus hands you both currencies and only one of them ever becomes a prize.
- Onyx Coins are the free, for-fun currency, and the 1,000 you get for registering live here. They power standard social play, have no monetary value, and cannot be redeemed for anything, no matter how many you stack. They are the sandbox, full stop.
- Games Cash (the in-app name for the currency Onyx's official rules call Sweeps Cash, awarded to you as Bonus Picks) is the side that can actually pay out. You cannot buy Games Cash directly; it only ever arrives as a bonus, which is precisely what the OS100 first-purchase offer awards. Win with it and you can redeem it for prizes, but only after it clears the playthrough and redemption terms below.
| Onyx Coins | Games Cash (Bonus Picks) | |
|---|---|---|
| How You Get It | 1,000 free at registration; buyable in coin packs | Awarded as a bonus (the OS100 offer); never buyable |
| Cash Value | None, for social play only | Redeemable for prizes after a playthrough |
| Part Of The Sign-Up Bonus | The free 1,000 coins | The up-to-100 in Bonus Picks |
The column that matters is the right one: everything that can ever become a payout lives under Games Cash, and none of it can be bought, only earned as a bonus like this one.
The one rule to remember: the 1,000 Onyx Coins are practice; the 100 in Bonus Picks (Games Cash) are the prize. That is why the free coins are a great way to learn the app and the Bonus Picks are the reason to bother with the $10 purchase at all.
That distinction is also the callback to the missing number from the top: the free coins never had a redemption gate because they never redeem, and the Bonus Picks have one Onyx chooses not to spell out. So the honest question for a sign-up bonus is not "how big is the number"; it is "what does it take to get the redeemable number out." Here is that answer, walked all the way through.
Turning 100 In Bonus Picks Into A Prize: A Worked Example
Say you claim the full bundle: 1,000 Onyx Coins for registering, then a $10 first purchase that lands you 100 in Bonus Picks (Games Cash). You put 10 of that Games Cash on an NBA guard to go over his points line in the promotional mode, the pick hits, and the winnings return as Games Cash. That balance is not a prize yet.
Two gates stand between that balance and a payout. First, the playthrough: Onyx requires Games Cash to be used at least once in an eligible game before it can count toward redemption, at odds of -500 or longer, and the rules let Onyx require more than one pass, so treat "one lap" as a floor, never a promise. A single required lap is very survivable; the risk is that each extra lap Onyx can require is another chance to bust the balance before it ever gets to leave. Second, the redemption minimum: your played-through Games Cash has to reach Onyx's minimum redemption amount before you can request a payout, and this is the number Onyx does not publish. You will not find it on the sign-up screen, and the widely repeated "20 Onyx Cash" figure is something review sites assert, not something Onyx states.
So the run that pushes your Bonus Picks balance up, clears the playthrough, and gets over Onyx's redemption threshold can be exchanged for a real prize; a balance that never reaches it cannot, however it got there. That two-gate path is the detail I keep coming back to, because it is the actual line between a high score and a payout, and it is why "how big is the bonus" was always the wrong first question.
How To Claim The Onyx Odds Sign-Up Bonus, Step By Step
Claiming both halves of the offer takes a few minutes.
- Tap our Onyx Odds sign-up link. Open our Onyx Odds sign-up link. It carries code OS100 and routes you to Onyx.
- Create your account and verify your details. Complete Onyx's registration and eligibility checks, including confirming your location so the app knows your state is eligible. Finishing registration lands your 1,000 free Onyx Coins, the no-purchase half of the bonus.
- Make sure code OS100 is applied. Signing up through our link should attach it automatically. If you see a promo field, enter OS100. This is the step that switches the first-purchase match on.
- Make your first $10 purchase. Buy your first Onyx Coin pack of at least $10 to trigger the match and land your up to 100 in Bonus Picks. Remember, no purchase is necessary to receive Games Cash through Onyx's free method; the $10 is only what unlocks this first-purchase bonus.
- Play, clear the gates, then redeem. Your 100 arrives as Games Cash. Make your picks in the promotional mode, clear the playthrough, reach Onyx's minimum redemption amount, and request your payout. Onyx allows up to 30 days to pay and one redemption request per account every five days.

New players only. Eligibility and location requirements apply; not available in every state. Onyx Odds is a sweepstakes social sportsbook, so there is no real-money wagering, and no purchase is necessary to receive Games Cash. Bonus Picks are credited as Games Cash that carries a playthrough requirement and a minimum redemption amount before redemption, not a guaranteed return. Subject to terms; confirm the current offer and full terms in-app before you buy.

Where The Onyx Odds Sign-Up Bonus Is Available
The sweepstakes model gives Onyx a wide footprint, but the bonus is not claimable everywhere. Per Onyx's official sweepstakes rules, the game is open to US residents 18 or older at the time of entry, excluding Alabama, California, Colorado, Connecticut, Idaho, Indiana, Louisiana, Maine, Michigan, Montana, Nevada, New Jersey, New York, Tennessee, Washington, and West Virginia ("and where otherwise prohibited"). Live in one of those states and no promo code changes the outcome, because the app will not let you play. One wrinkle worth knowing: Onyx's separate terms of use also reference Illinois and Maryland, so if you live there, treat your eligibility as unsettled until the app confirms it at signup. Sweepstakes rules shift as legislators revisit them, so eligibility can change, and the signup flow is the final word for your state.
That eligibility is downstream of the model itself. Because Onyx runs under sweepstakes rules rather than a state sports-betting license, no real money is wagered on your picks, which is the same legal distinction that decides where any of these platforms can operate. If that line is new to you, our explainer on whether prediction markets are legal walks through the same core idea from the event-contract side: a platform's legal model, not a state betting license, is what sets its map.
Making The Bonus Worth Claiming: Price The Pick First
Back to the two gates. Because the playthrough can force you to run your Games Cash through more than one pick before it ever reaches the redemption line, every one of those picks has to be worth making. A free stack of Bonus Picks lowers the cost of a bad pick; it does not turn a bad pick into a good one, and on Onyx the cost of a bad pick is an extra lap you did not want to run.
That makes pricing your picks the highest-leverage habit on this platform, more so than on a cash book. Onyx's markets are player props at heart (more or less on a line), and the same players show up on the boards at books like DraftKings, FanDuel, BetMGM, and Caesars. So a simple workflow before you tap a slip: take one Onyx prop, find the closest matching prop across the sportsbooks with the free OddsShopper Odds Screen, an odds comparison tool. The tool surfaces the best available price across 100-plus books and de-vigs it, stripping out the sportsbook's hold to leave the true, no-vig number, and lean Onyx's way only when its side reads as the better price once you have accounted for the playthrough. That is line shopping, pointed at protecting your Bonus Picks instead of your cash.
The read that matters: if the no-vig number pegs an over as the more likely side but your Onyx slip is on the under, the sharpest markets disagree with you, which is your cue to reconsider before you spend a lap on it. Player props tend to carry a heavier hold than a straight game line, so the price check earns its keep.
You are not chasing certainty; you are checking whether the pick Onyx offers lines up with where the sharpest real-money markets have it priced. Do that a few times and you stop guessing which side to tap, which is exactly what the two-gate playthrough rewards: every forced lap becomes a pick you would have made anyway, not a coin flip you are running just to unlock a payout. Onyx's current offer and the fine print live on our Onyx Odds current offer, and how to claim it page if you want it beside the rest of the cluster.
For the fuller picture of how a virtual-currency platform differs from the sportsbook you already use, our primers on how prediction markets work and prediction markets vs. sports betting cover that terrain, though those markets run under their own federal framework rather than Onyx's sweepstakes model.
Onyx Odds Sign-Up Bonus FAQ
What is the Onyx Odds sign-up bonus? It has two parts. Registering unlocks 1,000 Onyx Coins for free social play, no purchase necessary. Your first $10 purchase with code OS100 then gets you up to 100 in Bonus Picks (shown in-app as "Up to 100 in Games Cash on your first purchase"). You must be 18+ and in an eligible state.
Play responsibly. A sign-up bonus is a way to get started, not a reason to spend more than you planned. Only ever put up money you can afford to lose, and if it stops being fun, step away. Call 1-800-GAMBLER if you need help.
Is the 100 real cash I can withdraw right away? No. It arrives as Games Cash (awarded as Bonus Picks), the redeemable promotional currency. It becomes a prize only after you play it through (at least once, at -500 or longer, and Onyx can require more than one pass) and reach Onyx's minimum redemption amount. Confirm the current requirement in-app.
What is the Onyx Odds promo code for the bonus? Use OS100. Signing up through our link applies it automatically; if a promo field appears during registration, enter OS100. That code is what switches on the first-purchase match.
How much does Onyx Odds pay out, and what is the minimum to redeem? Onyx does not publish a numeric minimum redemption amount, so treat any specific "floor" figure you see on review sites as unverified. What Onyx does state: redemptions can take up to 30 days, and you can make one redemption request per account every five days. Check the exact terms in-app.
Bottom line: the missing redemption number is the single most important thing to confirm in-app before you buy in, because it is what decides whether a winning Games Cash balance can actually leave your account.
Do I have to spend money to get anything? No. Registering alone lands 1,000 Onyx Coins for free social play, and because Onyx is a sweepstakes, it offers a free, no-purchase way to request Games Cash. The $10 purchase only unlocks the additional first-purchase Bonus Picks.
What states is the Onyx Odds sign-up bonus available in? Per Onyx's official sweepstakes rules, it is open to US residents 18+ but not available in Alabama, California, Colorado, Connecticut, Idaho, Indiana, Louisiana, Maine, Michigan, Montana, Nevada, New Jersey, New York, Tennessee, Washington, or West Virginia. Onyx's terms of use also reference Illinois and Maryland, so treat those as unsettled. Eligibility can change, so the signup flow is the final word for your state.
Ready to claim it? Sign up for Onyx Odds with code OS100. Register for 1,000 Onyx Coins free, then spend $10 on your first purchase for up to 100 in Bonus Picks. No purchase necessary, 18+. Confirm the current offer in-app before you buy.
