TL;DR: To redeem any Duel.com promo or referral code, sign up using the referral link (e.g., duel.com/r/duel5 or duel.com/r/fuse) so the code applies automatically, or manually enter the code in the promo field during registration. Enter codes exactly in uppercase, then complete signup. For help when a code fails, see code not working.
Overview
Duel.com promo and referral codes like DUEL5 and FUSE unlock benefits such as increased rakeback and 100% RTP on Duel originals. You can enter a code in two ways: through a referral link (recommended) or by typing it into the promo field during signup.
Important: You can typically use only one referral code per account. Choose DUEL5 or FUSE before completing signup—you cannot usually change it later.
