Add your email and password, and accept the Terms of Service after confirming you're of legal age in a permitted jurisdiction.

Deposit and start earning rakeback
Fund your account with crypto and play eligible games. Rakeback accrues instantly on every qualifying wager — no unlock thresholds.
What the Code Unlocks
Duel.com doesn't do inflated deposit matches. The promo code instead switches your account onto its instant rakeback track:
Rakeback:50% of the theoretical house edge on each eligible bet is returned to you in real time. On a game with a 1% edge, that's $0.50 back per $100 wagered — win or lose, forever.
Boosted RTP: select Duel Originals variants run at up to 100% RTP for code users, effectively removing the house edge on those games.
Extras: leaderboard races with fixed prize pools, seasonal promos, and VIP progression all stack on top.

Duel.com Promo Code — FAQ
›What does the Duel.com promo code CSREF give me?
CSREF unlocks 50% enhanced rakeback on eligible games, up to 100% RTP on certain Duel Originals, and eligibility for daily, weekly and monthly cash-prize leaderboards. Rakeback is credited automatically per bet with no wagering requirements.
›Where do I enter the promo code on Duel.com?
