Duel

Duel Casino Bonus and Referral Code

Our referral programme rewards referrals of new players. When you enter a referral code during registration, your account is linked to the person who invited you. The code alone does not give you a deposit bonus or free starting credit.

18+. Gamble responsibly.

Promo codes, referrals and rakeback

Under the referral programme, the person who invited you may earn a commission. Rakeback is a reward you receive for your own play. With a promo code, the relevant promotion determines what you can claim and how to redeem it.

Referral Code

Links your new account to the person who invited you. They may earn a commission.

Promo Code

Lets you redeem a specific promotional reward. The offer's terms determine what you receive.

Rakeback

Gives you back a portion of the theoretical house edge on eligible games.

Even if someone advertises their referral code as a “bonus code”, it does not automatically entitle you to free spins or free credit. Those rewards must be explicitly included in a promotion.

Entering your referral code at registration

A referral code is optional when you register. Under “Register”, you’ll find “Referral code (optional)”. Selecting this option opens a field where you can enter the code provided by the person who invited you.

01

Registration

Create your account with a username and password.

02

Referral Code

Entering a code is optional. It links your account to the person who invited you.

03

Your account

Once registered, use your Duel account to log in and play.

The code doesn’t automatically give you free spins or extra credit. You can register without one. If you entered the wrong code or forgot to add it, ask our support team at [email protected] whether it can be added afterwards.

Earn commission from referrals

You can invite friends to Duel, and content creators and affiliates can also join our referral programme. When new players sign up through your code, you may receive commission based on their gaming revenue. An invitation alone doesn’t guarantee a commission.

Commission is calculated from gaming revenue under our programme terms, not as a fixed percentage of each deposit. The house edge is taken into account for slots and live games. With Duel Blackjack and Video Poker, suboptimal decisions can generate revenue on which we calculate commission. Other Originals with a theoretical RTP of 100% have no house edge for us to share with you.

Commission rates may change. Self-referrals are prohibited. Any extra rewards you promise through your code must be approved by us and actually paid out.

Promo codes and offer terms

A promo code only applies to its specific offer. The terms set out who is eligible, how long the code is valid and whether a deposit is required. Credit bonuses and free spins may also have wagering requirements, excluded games or withdrawal limits. There is no single set of terms for every code.

The “Referral code (optional)” field at registration is for referrals. You cannot redeem an unrelated voucher there simply because it is advertised online as a Duel promo code.

To redeem a promo code, follow the instructions for that offer. Entering a referral code does not activate an unrelated bonus promotion.

No deposit bonus

Registering with a referral code does not automatically give you free starting credit. Registering without a code does not, by itself, trigger a no deposit bonus either.

A no deposit bonus would be a separate promotion with a specific reward and its own eligibility terms. These may include wagering requirements and withdrawal limits. Age and country restrictions also apply to such promotions.

Rakeback on eligible games

On eligible games, you get back a portion of the theoretical house edge as rakeback. We pay this reward to you as the player, whereas referral commission goes to the person who invited you.

Your stakes and the game’s theoretical house edge determine the amount. Rakeback is therefore not a fixed percentage of what you lose in one evening. Rates and conditions may vary by game or promotion.

Game rules and win probabilities stay the same. However, receiving rakeback reduces your mathematically expected loss over many rounds. You can still lose more than you receive in rakeback.

Zero Edge on our Originals

Our Originals are built around Zero Edge. With optimal play, the mathematical house edge is 0% and the theoretical RTP is 100%. You don’t need a bonus to benefit from Zero Edge.

In Blackjack, you can only achieve this theoretical RTP with optimal decisions. Slots and live games from other providers have their own RTPs. Losses are still possible even with a theoretical RTP of 100%.

Bonus and referral FAQs

Does a referral code give me a deposit bonus?

Not automatically. The code links your account to the person who invited you. A deposit bonus would require a separate promotion.

Where do I enter my referral code?

During registration, select “Referral code (optional)” under “Register” and enter your code in the extra field. It is entirely optional.

Can I create an account without a code?

Yes. The referral field is optional. You don't need a code to register.

Will a referral code give me a no deposit bonus?

No. A referral code alone doesn't give you free starting credit. A no deposit bonus would be a separate promotion.

Who receives the referral commission?

The person whose code brought the new player to Duel. The amount depends on the game and our programme terms. It isn't a fixed percentage of the deposit.

Are rakeback and referrals the same thing?

No. You receive rakeback yourself on eligible games. Referral commission goes to the person who invited you.

What if I forgot my referral code?

You can still register without one. If you forgot the code or entered it incorrectly, contact our support team at [email protected]. We cannot guarantee that a referral can be added afterwards.
