Question 1

What is the RTP of Duel Crash?

Accepted Answer

99.9% (0.1% house edge baked into the bust formula directly).

Question 2

Is Duel Crash provably fair?

Accepted Answer

Yes — and stronger than per-seed verification. Each round commits to a drand random-beacon entry pre-round, so the randomness is anchored to a public, timestamped feed that even Duel cannot rewrite.

Question 3

How does Duel Crash differ from Stake / Roobet Crash?

Accepted Answer

Same player-facing game, different math. Duel uses a 32-bit slice from HMAC(serverSeed, drandRandomness) with no instant-bust rule (the 0.1% edge is baked in). Stake/Roobet use a 52-bit slice with a 1-in-33 instant-bust path.

Question 4

Can you predict Duel Crash bust points?

Accepted Answer

No. The drand beacon is unpredictable until publication; the server seed is committed pre-round and only revealed after.

Question 5

How do I verify a round myself?

Accepted Answer

Open any round in the history, copy the server_seed and drand_randomness, paste into the /verify/duel-crash verifier — the bust point is recomputed in your browser.
