Bonuses and promotions
Duel does not offer a classic welcome bonus, by design. Its article Why bonuses suck argues that what matters is your net expected loss, and that a game with no house edge beats a bonus on a game with a normal edge. The Zero Edge page describes the result: the house edge on Duel Originals is zero. Any other promotions are shown on the site when they run.
If you prefer a traditional deposit match, compare the bonus systems of the casinos on our list.
Deposits and payment methods
Duel is a crypto casino: you deposit and withdraw in cryptocurrency. The terms do not list the supported coins and networks; the cashier shows the options for your account. Choose the same coin and network in the cashier and in your wallet before you send funds.
Withdrawals and verification
Duel may request identity verification before processing a withdrawal. The terms say Duel does not profit from deposit or withdrawal fees; network or processor fees are paid by the user.
The terms do not publish withdrawal limits or processing times. Duel may ask you to verify your identity before it processes a withdrawal, so keep your documents ready. Our withdrawals guide explains how these checks work.
Games
Duel describes zero-edge house games with a 100% return to player and separate third-party casino games; the zero-edge claim applies to Duel's own games, not to the whole catalogue.
A 100% RTP is a long-run average for a specific game; any single session can still lose. Read how RTP and house edge work before comparing games.
Licence and safety
Duel is operated by Immortal Snail LLC. The Anjouan licence register lists Immortal Snail LLC as the holder of licence ALSI-202411026-FI1 for duel.com, status Valid.
The terms of service also set a six-year inactivity rule, after which the operator may take a dormant balance, so log in from time to time if you keep funds there.

Duel's terms exclude players from, among others, the United States, the United Kingdom, France, the Netherlands (including Curaçao), Germany, Spain, Australia, Lithuania, Slovakia, the United Arab Emirates and Venezuela; the full list of 30 territories is in the terms.
The terms make you responsible for checking that online gambling is legal where you are. Do not use a VPN to get around a restriction.

Duel FAQ
Is Duel a legitimate crypto casino?
Duel is run by Immortal Snail LLC and appears in the Anjouan licence register with licence ALSI-202411026-FI1, status Valid.
What does zero edge mean at Duel?
Duel describes its own house games as zero-edge, with a 100% return to player. That applies to Duel's games, not to the third-party slots, and it is a long-run average rather than a guaranteed result.
Does Duel have a deposit bonus?
No. Duel deliberately skips classic deposit bonuses and offers zero-edge Originals instead, so there is no wagering to clear.

Duel's terms say it does not profit from deposit or withdrawal fees. Network or payment processor fees are paid by the player.
