- Enter the code shown on this page in the "Got a sign up code?" field when you sign up; Onyx publishes no way to add it later.

The catch
- Onyx does not publish what this code gets a new player, and the sign-up form takes one code with no way to change it later. Its own offer without a code is spend $10, get 50 in bonus picks, and review sites advertise 100 to 200 for $10 with their codes, so decide before you sign up.
- The bonus picks need a purchase first, a bonus pick pays only its winnings, and bonus picks expire if you do not use them in time.
- Bonus Onyx Cash has to be played at least once at odds of -500 or longer before you can redeem it, and Onyx can ask for more. Winnings from mini games like Onyx Blackjack and from Onyx Cash Out can never be redeemed, and Onyx Cash expires after 30 days without a login.
- Redeeming can require a photo ID, a selfie, proof of address and your SSN. Onyx can refund your purchases instead of paying a redemption, and may charge processing fees.
- App Store reviews are weak lately: 34 of the 50 posted Sep 7 to 22, 2026 are one-star, over slow or refused cash-outs, suspended accounts, and sign-up and referral bonuses not paid after a first purchase. The overall rating is 4.8 from 14,576 ratings.
- Not available in AL, CA, CO, CT, ID, IN, LA, ME, MI, MT, NV, NJ, NY, TN, WA or WV, and Oklahoma from Nov 1, 2026. Its Terms of Use also forbid Illinois and Maryland, though its Sweepstakes Rules do not list them, so the code is hidden there too. In AL, CA, CO, ID, IN, LA, ME, NJ and WV the same app offers real-money prediction trading instead.
