Math & RTP Model
The math, in full
Crypto Flight X is a crash-style multiplier game. The return-to-player and full probability distribution are defined by a single public formula — there are no hidden tables. This is the exact model your testing lab and compliance team can certify against.

Probability distribution
The chance that any round reaches a multiplier m or higher is:
P(crash >= m) = (1 - houseEdge) / m With houseEdge = 0.05: P(crash >= 2.00x) = 0.475 (47.5% of rounds) P(crash >= 5.00x) = 0.190 (19.0% of rounds) P(crash >= 10.00x) = 0.095 ( 9.5% of rounds) P(crash >= 100x) = 0.0095 ( 0.95% of rounds)
Because expected return is the same at every cash-out target, the theoretical RTP is constant at 1 − houseEdge = 95% regardless of player strategy. The minimum result is always 1.00x.
Exact crash-point formula
Each crash point is derived deterministically from the provably-fair seeds. Run this in any language and you get the identical result:
h = first 52 bits of HMAC_SHA256(serverSeed, clientSeed + ":" + nonce) fair = floor((100 * 2^52 - h) / (2^52 - h)) / 100 crashPoint = max(1, floor(fair * (1 - houseEdge) * 100) / 100)
Every output is reproducible from the published seeds — see the verifier on the Provably Fair page.
Operator-configurable parameters
- • House edge / RTP — default 5% (95% RTP); adjustable 2–10% per operator.
- • Max win cap — default 10,000x; set lower for tighter liability limits.
- • Min / max bet — controlled entirely by your wallet integration and lobby.
- • Currency — any token your wallet supports (USDT, BTC, ETH, etc.).
