Sign In

Getting into Onyx Odds Casino is built around speed and simplicity — but it’s not the same as a traditional app login. Onyx Odds runs entirely through a mobile browser, so signing in starts with your phone and a quick trip to the site. New accounts are credited immediately with 1,000 Onyx Coins for play, and a first purchase of $10 nets 25 Onyx Cash when you use the applicable promo code. Those incoming balances are what let you turn predictions into prize eligibility or keep playing for free.

How the sign-in and sign-up flow works

Tap the mobile site, choose Sign In or Register, and follow the prompts to create an account with your email and secure password. The no-deposit welcome — 1,000 Onyx Coins — is applied at registration (promo code BOOKIES may be optional). If you decide to make a first purchase, use GET25 or BALLISLIFESBT to claim the spend-$10-get-25 Onyx Cash bonus. Because Onyx Odds operates on a sweepstakes dual-currency model (Onyx Coins and Onyx Cash), you’ll see both balances in your account dashboard after signing in.

Security, payments, and when support helps

Onyx Odds supports standard payments that you can link from your account: ACH, American Express, Discover, MasterCard, and Visa, all in USD. Chat support is available from the mobile site and you can email contact@onyxodds.com for slower queries. Expect to verify payment details and identity if you request redemptions — the platform caps sweepstakes redemptions at $5,000 in Florida and New York per entry period — so keep your verification docs handy to avoid delays.

Sign in today to catch limited windows and VIP gains

Signing in immediately after registering is the fastest way to claim the 1,000 Onyx Coins and position yourself for the $10 → 25 Onyx Cash offer. Onyx Odds runs occasional reloads, cashback-style promotions, and VIP point boosts that appear in-app or via email; these promotions can disappear or change without notice, so claiming bonuses while they’re live matters. Regular sign-ins also build VIP points faster, moving you into higher tiers that bring bonus opportunities and exclusive rewards.

Things to consider before logging in

Onyx Odds is mobile-only — there’s no downloadable app — which can be a plus for quick access but a constraint if you prefer desktop play. The sweepstakes model means Onyx Coins are for entertainment and Onyx Cash is the redeemable currency; read the terms carefully for playthrough requirements tied to cash redemption. Several states are restricted (AL, CO, ID, LA, MI, MT, NV, TN, WA), and promotional codes or bonus mechanics may vary by location. Finally, promotions and maximum redemption limits are subject to change, so don’t assume offers you see today will still exist tomorrow.
