No profit promise
Expected value does not guarantee an individual outcome.
Published mechanism
Base edge minus stated rakeback
Duel's Zero Edge FAQ describes eligible Originals as having a 0.1% base edge. While a user remains within the allowance, the operator says a 0.1% instant rakeback offsets that edge.
This is a description of net expected economics, not a cash-back guarantee for every losing round and not evidence that a bankroll cannot fall.

- 01
Confirm eligibility
Check the current product page and account view rather than assuming every wager qualifies.
- 02
Find the current allowance
Limits and reset mechanics are dynamic and should not be copied from an old promotion.
- 03
Understand the post-limit state
Once the allowance is used, the economic treatment described by Duel changes.
- 04
Keep variance separate
A zero expected house edge does not flatten the possible sequence of wins and losses.
What the claim does not establish
Zero Edge has strict boundaries
No payment promise
It says nothing about KYC, account review or withdrawal timing.
No universal coverage
Different games and modes may use different rules.
No legal conclusion
A game feature does not determine whether access is lawful in a location.
Compare Zero Edge with RTP
Use the 99% RTP model to see how a 1% edge affects theoretical turnover, then compare that concept with the stated Zero Edge allowance. For outcome integrity, read the separate Provably Fair guide.
Key points
Frequently asked questions
Does Zero Edge mean I cannot lose?
No. It describes expected game economics under stated conditions. Variance can still produce substantial short-term losses.
How does Duel describe the model?
The published FAQ says eligible Originals have a 0.1% base edge offset by 0.1% instant rakeback while the user remains within the Zero Edge allowance.
What happens after the allowance is used?
The FAQ says the instant rakeback stops until the allowance resets, while original slots use their own post-allowance edge treatment. Check the current wording before play.
Is 100% RTP the same as a guaranteed refund?
No. It is a long-run theoretical value and does not determine a single session.

Gambling is not a way to earn money
Play only where it is legal, set a hard limit in advance and never chase losses.
