What is Duel casino?
Duel is an online casino and sportsbook at duel.com, run by Immortal Snail LLC from Nevis under an offshore license from Anjouan in the Comoros. It launched in July 2025, and its founder, Ossi Ketola, had already run the Counter-Strike skin-betting site CSGOEmpire since 2016.
Three things set it apart from the hundreds of other crypto casinos:
- Zero edge on its own games. Duel's Originals (Blackjack, Dice, Crash, Mines, Plinko and others) pay back 100% of what you bet for the first $50,000 you wager each day, at up to $1,000 a bet. After that a small house edge returns. How Zero Edge works.
- No welcome bonus. Instead of a deposit match with wagering, Duel pays part of the house edge back on every bet: 50% on slots, 60% on its live blackjack. Rakeback explained.
- Attention-first marketing. A 24/7 live blackjack stream with guests like Mike Tyson, a fight promotion called Duel: Arena, and a founder who gambles eight-figure sums on camera. It brings the traffic, and some of the controversy.

What changed at Duel recently
The things that affect players, newest first.
Sweden bans Duel's operator
Spelinspektionen found Swedish language, kronor and marketing on an unlicensed site. Duel argued that Swedish is an international language.
Zero Edge now has a visible daily limit
$50,000 a day at up to $1,000 a bet, read straight off Duel's own panel. After that, the edge scales with your stake.
Two blackjack games, two different RTPs
The streamed live table returns 99.41% to 99.46%. Only the computer-dealt Original is zero edge.
X sues Duel's operator in Texas
Allegations that people acting for Ketola bribed X staff over suspended accounts. Unproven so far.
Gypsy Crusader vs King Azoulay
A split decision, a crowd brawl and a Florida legislator asking the state to pull the promoter's license.
