Duel Provably Fair
How Duel.com's provably fair positioning works, what seed verification proves, and why 100% RTP and zero house edge are not win guarantees.

Provably fair gambling means a game can show that a round was determined by committed random inputs — typically a hashed server seed, a client seed, and a nonce — rather than silently edited after the bet.
What it proves
When implemented, it proves that the operator did not swap the result after seeing the stake. It does not prove that you will win, that a third-party slot is fair, or that a sportsbook price is generous.
What Duel.com publishes
Duel.com markets Originals as provably fair and around 100% RTP / zero house edge. The Zero Edge FAQ is the primary public explanation of the 0.1% base edge and allowance-based rakeback. Verify seeds in the live Originals client.
100% RTP and zero house edge
100% RTP does not mean every player wins. It describes long-run expected return under the stated rules, inside the stated allowance, before variance. A player can still lose the session, the week, or the bankroll.
Zero house edge does not mean there is no losing session.It also does not apply automatically to slots, live tables or sports bets.
