Instant Welcome Free Play: 1,000 Onyx Coins (No Code, No Deposit)

New users can receive 1,000 Onyx Coins as a welcome no deposit bonus - and there’s no promo code to remember. Sign up and it’s credited automatically, giving you immediate play value for sports predictions across football, basketball, baseball, and soccer.

This bonus comes with zero wagering requirements because Onyx Coins are non-redeemable. That makes it ideal for testing the platform, checking out how predictions work, and getting comfortable before you decide to purchase Onyx Cash.

The offer is ongoing, but eligibility depends on your location. Onyx Odds Casino is not available in: Alabama, California, Colorado, Connecticut, Idaho, Illinois, Louisiana, Maryland, Michigan, Montana, Nevada, New Jersey, New York, Tennessee, Washington, and West Virginia.

First Purchase Bonus: Use Code ONYX100 for 100 Bonus Picks

If you’re ready to level up from free play, the first purchase bonus is the main event. Make a minimum $10 purchase and enter code ONYX100 to score 100 Bonus Picks (Onyx Cash equivalent) for extra play volume across the site - sports predictions, slots, table games, and live casino.

This bonus is designed to turn one purchase into a longer run. The playthrough is straightforward too - just 1x on your total Onyx Cash balance. After that requirement is met, Onyx Cash becomes withdrawable (non-sticky setup), so you’re not forced to burn through winnings before cashing out.

Redemptions are capped at $1,000 per week and $5,000 per month, with a minimum $20 Onyx Cash balance required to redeem. Florida and New York have an additional limitation of $5,000 per sweepstakes entry period, with any excess deferred - and note that New York is on the excluded list for these promos anyway.

No Purchase Route: Mail-In Bonus Worth 5 Onyx Cash Per Request

Onyx Odds Casino also offers a mail-in bonus option for free entry sweepstakes value. You can request 5 Onyx Cash per mailed request, up to 100 requests, with a 1x playthrough required before redemption eligibility.

This path is a strong fit if you want a slower-build bankroll method and don’t mind the manual process and verification timeline. Once approved, the Onyx Cash can be used across sports predictions and casino games, just like purchased balances.

The same excluded states apply here: Alabama, California, Colorado, Connecticut, Idaho, Illinois, Louisiana, Maryland, Michigan, Montana, Nevada, New Jersey, New York, Tennessee, Washington, and West Virginia.

Cashout Rules to Know Before You Start Firing Picks

Onyx Odds Casino keeps the bonus math simple, but you’ll want to keep a few key rules in mind. Most importantly, identity verification is required for redemptions - expect standard checks such as a government-issued ID, proof of residence, and a live selfie.

Also note that the platform takes promotion integrity seriously. Multiple accounts, bonus abuse, or any attempt to manipulate entry processes can lead to suspension and forfeited benefits. Purchases are final with no refunds, and promotions can be changed or removed without notice.

The Smart Way to Use These Promos Right Now

If you want maximum value with minimum friction, start with the automatic 1,000 Onyx Coins to get comfortable with sports predictions risk-free. When you’re ready to add real momentum, the ONYX100 first purchase bonus turns a $10 minimum into extra bonus picks that can stretch your session across both sports and casino titles powered by Pragmatic Play.

Just make sure you’re in an eligible US jurisdiction and keep the weekly and monthly redemption limits in mind as you plan your run.
