Crypto Casinos with Zero House Edge

Duel Casino: 100% RTP

Duel Casino is a crypto-native platform built around its in-house “Duel Originals,” offering a streamlined experience for players who prefer fast gameplay, clean design, and blockchain-based transparency.

Alongside a full sportsbook and traditional casino content, Duel stands out for developing its own suite of provably fair games.

What separates Duel from most crypto casinos is its selection of zero percent house edge titles. Several Duel Originals — including Dice, Blackjack, Plinko, Crash, Mines, Keno, and Castle Roulette — are listed at 100% RTP.

In simple terms, that means there is no built-in mathematical advantage for the house over the long run on those specific games.

Instead of relying on traditional house edge margins, Duel positions these games around provably fair mechanics and alternative revenue models, allowing players to compete on even mathematical footing.

For anyone specifically seeking zero house edge crypto gambling, Duel is one of the clearest examples of a platform structuring its in-house titles around a true 100% RTP model.

Metawin: 100% RTP Boosted by Rewards

MetaWin is a licensed Web3 crypto casino that combines a large third-party game library with its MetaWin Originals. Players can access slots from major providers, table games, and live casino content, alongside a growing collection of fast-paced in-house titles, all designed with blockchain integration at the core of the platform.

MetaWin stands out because it has a dedicated Zero House Edge Originals category. Unlike Duel — which structures most of its Originals at 100% RTP — MetaWin runs a mixed model.

Many of its Originals operate with a traditional house edge, but it also offers a clearly defined set of games built at 100% RTP.

The current Zero House Edge lineup includes Roulette Zero, Limbo Zero, Mines Zero, and Dragon Tower Zero, each operating at 100% RTP with no built-in house advantage.

Instead of players earning through margin on those games, MetaWin leans on a broader reward ecosystem that includes frequent rakeback, daily cashback, and rank-based bonuses. In effect, the value that would normally be taken as house edge is redistributed through its reward structure.

Gamdom: RTP 100%

Gamdom is a crypto casino and sportsbook that combines a full provider-backed casino lobby with its own suite of in-house Gamdom Originals. Alongside slots and live games from major studios, Gamdom has focused heavily on developing fast-paced instant titles under its Originals brand.

Where Gamdom stands out is its decision to set all Gamdom Originals to 100% RTP. Games such as Dice, Crash, Roulette, Hilo, Plinko, Mines, Keno, Pocket Dice, and Limbo are listed at 100% RTP, meaning there is no built-in mathematical advantage for the house on those titles.

The zero edge is structured directly into the game return itself, rather than being compensated through a separate rewards adjustment.

It’s important to note that this 100% RTP applies specifically to Gamdom Originals. Third-party slots and live casino games still operate under their standard provider RTP models.

By separating its Originals from its wider casino catalog, Gamdom offers players the option to play true zero-house-edge titles while maintaining a traditional casino offering elsewhere on the platform.
