Fairness
Provably Fair vs RNG: Randomness and Proof Are Different
RNG and provably fair are often treated as competing labels. They are better understood as two layers. The random number generator supplies unpredictable input. The fairness record supplies evidence about how that input became your result.
A strong system needs both. Predictable input would let someone anticipate outcomes. Missing records would leave a player unable to check whether a completed outcome matches what the server had committed to use.
What the RNG does
Havoc Win’s game rail uses a cryptographically secure generator seeded with secret material. The game engine consumes that stream to choose reels, cards, pockets, paths or other game-specific values. The browser receives the result and animation data; it does not decide the payout.
Random does not mean every visible outcome has equal probability. The game rules map the random stream through a paytable or state machine. A common symbol can be more likely than a top prize while each round still begins from unpredictable input.
What the proof layer does
- Commitment: a hash identifies the secret server seed before the relevant play.
- Client seed: player-settable input is mixed into the stream.
- Nonce: a counter keeps rounds under the same seed pair distinct.
- Deterministic engine: the same inputs and actions reproduce the same result.
- Replay record: the settled outcome and audit inputs can be compared later.
A commitment is useful because the server cannot reveal a different secret later without producing a different hash. A replay is useful because it checks more than the hash: it runs the game logic again and compares the reproduced outcome with the stored record.
What neither layer proves by itself
A secure RNG does not tell you the paytable is generous. A matching replay does not make a rare result common. Neither one guarantees a win, removes volatility or changes the long-run house edge.

Frequently asked questions
Is provably fair the same as an RNG?
No. The RNG produces unpredictable input. Provably fair describes the evidence and deterministic process used to show that committed input maps to the recorded result without a later rewrite.
Can a game use both?
Yes. Havoc Win uses a cryptographically secure random generator for round input and stores the data needed to reproduce settled results. Randomness and verifiability serve different jobs in the same system.
Does provably fair mean a game has no house edge?
No. It can prove that a result followed the committed inputs and game rules. The paytable can still include a mathematical house edge, which is described by RTP rather than fairness proof.
