Zero House Edge Action: Castle Roulette Brings Medieval Mayhem & 100% RTP to Duel Casino

Ready to get medieval at Duel.com? The casino's brand new Castle Roulette is bringing a fresh twist to live casino gaming, combining medieval-inspired visuals, live presenters and multipliers reaching up to x48. But there's one feature that's really turning heads: the game advertises a whopping 100% RTP under its standard rules!

Available at Duel Casino, Castle Roulette swaps traditional numbered pockets for a colourful multiplier wheel. You pick your target, place your bet and watch the action unfold, with just 13 seconds to make your move each round.

Castle Roulette keeps the gameplay simple, but there's plenty of variety in the betting options. You can choose from six multipliers — x2, x4, x8, x16, x24 and x48 — with the arrow deciding which one comes out on top.

Naturally, the bigger multipliers have fewer sections on the wheel. The x2 option has 24 sections, while x48 has just one, making those top-end payouts a much less frequent sight. Pick the winning multiplier and you receive the corresponding payout; land on something else and your bet is lost.

The medieval setting adds a little extra atmosphere, too. Live presenters host the action from a professional studio, while player chat lets you interact with others as the rounds unfold. There's even a history feature to check previous results between spins.

The biggest feature is Castle Roulette's advertised 100% return to player (RTP), which corresponds to a theoretical zero house edge under its standard rules. Its multiplier structure is designed around that return, giving the game a distinctly different pitch from conventional casino roulette.

There is, however, an important condition to keep in mind. Castle Roulette has a daily wager limit of $50,000, and the supplied rules state that exceeding it triggers a house edge based on bet size until the next reset. So, while the advertised RTP is certainly eye-catching, it isn't an unconditional guarantee — and individual results can still go either way.

The game also includes built-in verification tools, allowing you to check the fairness of individual rounds directly through the interface. It's a useful extra for players who like a little more transparency behind the action.

If you're keen to give Castle Roulette a spin, Duel Casino's wider catalogue offers more than 1,000 games to explore. You can use our Duel referral code for full access to the collection, where you'll find roulette variations and tons of other entertainment all under one roof.

Just make sure you understand the wager-limit rules before playing — then settle in and see where the wheel takes you.
