Duel Castle Roulette
Castle Roulette is Duel.com's in-house wheel, not a live-dealer roulette table. Layout, zero, and inside-allowance edge can all differ from a studio wheel.

Castle Roulette is Duel.com's in-house wheel, not a live-dealer roulette table. Layout, zero, and inside-allowance edge can all differ from a studio wheel.
How it works
Roulette pays even-money outside bets and longshot inside bets. A single-zero European wheel is already a different edge from a double-zero American wheel. Confirm which layout Castle Roulette uses in the live client before comparing it to live casino roulette.
RTP and house edge
If Castle Roulette is treated as an Original, Duel.com's allowance-based 0.1% rakeback model is the relevant published mechanic — not the classic 2.7% European wheel edge — until the allowance is exhausted. Verify in-product.
100% RTP does not mean every player wins. Zero house edge, when it applies, does not remove variance, losing sessions, or the daily allowance cap Duel.com describes.
Variance
Low on even-money bets, high on straight-up numbers.
Pros
- A wheel product inside the Originals framework.
- Easier to compare with live roulette on the same site.
- Even-money bets are simple to reason about.
Cons
- Name and art can hide rule differences.
- Inside bets remain high variance.
- Live-dealer roulette is a different product with provider math.

Frequently asked questions
Is Duel Castle Roulette 100% RTP?
Duel.com markets Originals around 100% RTP / zero edge inside a published daily allowance. After that allowance, Duel.com says a house edge returns. Check the live client. 100% RTP is not a session win guarantee.
