This is the registration walkthrough. Why the code exists, stacking rules, and missed-code recovery live on the promo code page. KYC expectations: no KYC.

How to register

Open the partner URL. Visit https://duel.com/r/duelhelp so the DUELHELP track is intact before you type anything.
Create the account. Register with a fresh email (or the method Duel presents). Use a password manager. 18+ only.
Enter the referral code. Tick the optional referral / promo field and paste DUELHELP. Confirm it is visible before you submit. It typically cannot be added later.
Deposit. Send supported crypto to the wallet address, or use Deposit with Cash to buy crypto on-site.
Play and claim. Open eligible games, then claim rakeback from Rewards when it accrues.

If the referral box is missing

You opened duel.com without the partner URL — start again from https://duel.com/r/duelhelp.
The field is collapsed under “Referral code (optional)” — tick it, then paste.
You already submitted. Support may not backfill. A clean signup is cheaper than a ticket.

After signup

Set a client seed you control before Originals volume.
Test a small withdrawal before you need a large one.

Geo and age

18+ only. Restricted jurisdictions apply. If Duel blocks your region, do not VPN against terms — find a legal local operator instead.
