Duel blackjack: the exact rules, the exact edge.

Not a review. The ruleset Duel actually deals, solved from scratch, with every con left in - the terms clauses casinos hope you skip are below.

The ruleset

3:2 on blackjack is the rule that matters most; a 6:5 table triples the edge before you play a hand. No DAS costs a little; it is priced in below.

What it costs you

Rakeback is shown as what it is: a rebate on the toll, not an edge. At 60% back the game costs about a quarter of a percent, which makes Duel one of the cheapest blackjack tables anywhere. It is still a toll.

The terms that matter

Recreational-only clause
The house reserves the right to close accounts it judges professional. Winning consistently is, by the letter of the terms, a violation.
Screen-capture clause
The terms permit recording your screen during play. Assume any tool running beside the game is visible.
KYC at $2,000 to $3,000 cumulative
Identity verification triggers on cumulative volume. Plan for it before a withdrawal, not during one.
US restriction
US players are restricted, and the restriction is enforced at withdrawal - the worst possible moment to learn it.
