First purchase perks: stack Onyx Cash with a promo code

Make a qualifying purchase and add real promo value. Use code ONYX100 with a minimum $10 deposit to receive 100 Onyx Cash (Onyx Cash must be wagered at least one time in Sweepstakes Cash games before becoming eligible for redemption). Onyx Odds also runs instant top-up deals such as Spend $10 Get 25 Onyx Cash — watch the promotions panel after sign-up and act quickly while these boosts are available.

Mail-in and special entry options

Prefer a no-card route? Mail-in entry promos can award Onyx Cash after manual opt-in. These offers require the same 1x wagering rule for redemption and are subject to weekly and monthly cashout caps. Check promo details during registration to grab every chance to increase your balance.

What you need to know about Onyx Cash and cashouts

Onyx Cash is designed to turn into withdrawable funds after play: it must be used in Sweepstakes Cash games and meet the 1x play requirement. Redemptions are capped at $1,000 per week and $5,000 per month. Any Onyx Cash will be forfeited after 30 days of account inactivity, so keep the momentum going. Remember, Onyx Coins are credited automatically on sign-up and expire after 60 days.
