Client Seed

Client seed is a random string of characters provided by the player that is combined with the server seed and a nonce to generate a provably fair game outcome in crash gambling.

In a provably fair system, no single party controls the result. The casino supplies a server seed (hashed before the round so it cannot be changed), and the player supplies a client seed. Both values are fed into a cryptographic function alongside a nonce — a counter that increments with each bet. The crash multiplier is the direct output of that calculation, meaning neither the casino nor the player could have manipulated it after the seeds were committed.

Most crash games assign a default client seed automatically when you register or start a new session. You are free to change it to any string you choose — a random word, a number, anything — before a round begins. Changing it does not improve or reduce your odds; the house edge stays the same regardless of what string you enter. What it does do is give you independent input into the outcome, which is the whole point of the provably fair model. Games like Pigaboom implement this system so players can verify every result without relying solely on the casino’s word.

After a round ends, you can audit the result yourself. Take the server seed (revealed post-round), your client seed, and the nonce for that bet, run them through the published hashing algorithm, and you will reproduce the exact multiplier the game generated. If the numbers match, the round was fair. If they do not, something is wrong. This is why keeping a record of your client seed matters — without it, you cannot complete the verification chain.

• Default seed: Auto-assigned; safe to use, but you have no way to prove you chose it independently.
• Custom seed: Any string you enter yourself; strengthens your personal audit trail.
• Changing seeds: Only takes effect from the next round onward, never mid-round.
