About Duel.com
The New Era of Crypto Gambling — No House Edge, No Apologies
Duel.com is a cryptocurrency-based casino and sportsbook that challenges the fundamental business model of traditional online gambling. Launched in July 2025, Duel distinguishes itself by offering proprietary games with a 100% return-to-player (RTP) rate—meaning zero house edge on core gameplay. The platform is licensed by the Government of the Autonomous Island of Anjouan and operates through Immortal Snail LLC, registered in Nevis.
The Story Behind Duel.com
Duel.com was launched in 2025 by Finnish entrepreneur Ossi “Monarch” Ketola, the founder of the Counter-Strike 2 skin-gambling site CSGOEmpire. Ketola founded CSGOEmpire at age 18 using an approximately €11,000 loan before transitioning to the broader crypto gambling space. Ketola founded Duel Casino in July 2025 through Immortal Snail LLC, pitching it as a crypto casino built around proprietary games with a 100% return-to-player target. The platform represents an attempt to disrupt industry-standard practices by removing the traditional house advantage from original games.
Your Needs, Our Focus
Duel’s original games include Dice, Crash Games, Plinko, Blackjack, Mines, and Keno—all with mathematically even odds. The platform also offers over 6,000 third-party provider slots from Pragmatic Play, NetEnt, Play’n Go, and others with standard RTP, where the platform earns its usual margin. Beyond casino games, Duel operates a full sportsbook for users seeking cryptocurrency-based wagering on sporting events.
What Makes Duel Stand Out
The platform’s core differentiator is 100% RTP on proprietary games—zero house edge, meaning the house doesn’t take a single percent on the original games. Duel also features an instant rakeback mechanism on third-party slots. The platform’s in-house games are designed with “provably fair” technology, allowing users to independently verify results. This approach fundamentally differs from traditional crypto casinos that operate with a 3–4% margin, and conventional brick-and-mortar casinos that take even more.
Why Shop Directly with Duel.com
Duel operates as a self-custodial cryptocurrency platform, meaning deposits and withdrawals are handled directly on-chain without traditional payment processors. The platform is licensed and regulated by the Government of the Autonomous Island of Anjouan, Union of Comoros, under License No. ALSI-202411026-FI1. Registered users can access live customer support and participate in community features including high-score leaderboards and referral programs. The platform emphasizes responsible gambling, directing users to resources like GambleAware for support with problem gambling.
