Promo codes: where they come from and what they lock

A promo code is a short string you enter at registration or deposit to activate a specific offer. Plenty of websites list "exclusive codes". This site publishes none. Here is why, and what to know before typing a code anywhere.

Who creates the codes

Codes are created by the operator, often with partners who each get their own code. A code is therefore largely a tracking tool: it tells the operator where you came from. It does not necessarily mean a better deal than you would get without it — often it triggers the very same offer with the very same terms.

What a code triggers

A code activates an offer — and every condition attached to it. Enter a code with a deposit and that deposit may be locked behind wagering, bet limits and deadlines. Read the terms of the offer a code belongs to before using it.

Question	Why it matters
Which offer does the code activate?	The code is only a key — the terms follow the offer
Is the code still valid?	Expired codes may trigger a different offer
Where did the code come from?	Codes from unknown sources can be bait
What happens to the deposit?	It may be locked until wagering is met

Amounts, percentages, requirements and deadlines are set by the operator and can change — the bonus terms on the operator's site are what apply.

Fake codes and phishing

Messages offering "secret codes" can be attempts to lure you to a fake site that imitates a casino. Never enter log-in or card details on a page reached through a code in a message. Go to the operator's site the usual way. More on fake copies is in mirror sites and blocking.

Codes and urgency

Many codes are valid only briefly: "until midnight". That is meant to make you act before thinking. No code is valuable enough to justify a deposit you had not planned.

Go to the offer

Regulated markets

Where regulators restrict bonus incentives, promo codes for bonus offers largely disappear. Seeing a stream of codes is a reminder that the offer sits outside those protections.

Frequently asked questions

Where can I find a Duell promo code?

This site publishes none. Any codes and their terms are on the operator's site.

Does a promo code give a better deal?

Not necessarily. A code is often a tracking tool that triggers the same offer with the same terms.

Can a promo code be a scam?

Yes. Messages with codes can lead to fake sites that steal log-ins. Always go to the operator's site the usual way.
