Why it matters
A 100% long-run return claim does not remove short-term variance. Duel also says it returns 50% of the stated house edge on standard third-party slots, which is a different mechanism from zero-edge Originals.
Key points
- 11 captured Duel Originals carried the 100% RTP label
- Provably fair documentation uses server seed, client seed, nonce and a pre-bet hash
- Daily and monthly leaderboards are cash competitions, not welcome bonuses
What to verify
Use the provably fair checker for supported house games and confirm the rules before each session. Roadmap features remain plans until they appear as working products.
