The Three Ingredients
Every crash result is calculated from three transparent inputs — no hidden tricks
Server Seed
A random 32-byte string generated by MemCasino. Its hashed version is published before the round starts so you can verify after.
Client Seed
A string you control. Change it any time from your dashboard to prove the game can't be manipulated against you.
Nonce
A counter that increments with every bet. Combines with the two seeds to produce a unique, non-repeating hash for every single round.
Why Provably Fair Beats "Trust Me"
Traditional casinos ask for trust. We hand you the proof
Fully Transparent
Every input and every result is publicly visible. No hidden RNG, no server-side manipulation.
Cryptographically Secure
Powered by HMAC-SHA256 — the same algorithm used by banks, exchanges and VPNs worldwide.
You Control the Seed
Change your client seed any time. The casino can't predict or influence your results.
Historical Proof
Every past round is stored with its hashed server seed. Verify any result long after it happened.
Open Algorithm
Our crash-point formula is public. Independently audited. Even you can recompute it in Python.
No House Advantage on RNG
House edge is baked into the multiplier curve — never into the randomness itself. Provably fair, provably consistent.
Fresh Seeds Every 24 Hours
We rotate server seeds daily so no advantage can ever accumulate
Publish Hash
At the start of a new cycle, we publish the SHA-256 hash of the upcoming server seed.
Play Normally
All rounds during the cycle use this server seed combined with your client seed and nonce.
Reveal Seed
After 24h, the un-hashed server seed is revealed. You can now verify every round of the cycle.
New Cycle
A brand-new server seed is generated and its hash published. The cycle repeats — forever.
Frequently Asked Questions
Everything you need to know about our fairness system
It means every game result can be independently verified by you (or anyone) after the fact. The casino can't change the outcome without detection, because the seeds and algorithm are public and the server seed is revealed after each 24h cycle.
No. The crash point is derived from HMAC-SHA256(server_seed, client_seed:nonce). Since you control the client seed and the server seed is hashed before the round, the casino cannot influence the outcome without being caught when the seed is revealed.
Log in, open your Dashboard → Settings → Provably Fair. You can type any text as your new client seed or generate a random one with a single click. It takes effect on your very next bet.
Very rare, but possible. If the computed crash point falls below 1.00x, we automatically set it to 1.00x — meaning the round instantly crashes. This happens roughly 1 in 100 rounds and is part of the house edge.
Yes. Once a 24-hour cycle ends, the server seed for that cycle is revealed in your dashboard. You can then paste it into the verifier above together with your client seed and the round's nonce to confirm the crash point.
Absolutely. We publish reference implementations in our developer docs. The core algorithm in Python is:
import hmac, hashlib
digest = hmac.new(bytes.fromhex(server_seed), f"{client_seed}:{nonce}".encode(), hashlib.sha256).hexdigest()
# then convert digest → crash_point via our public formula
