Provably Fair: Every Result Is Verifiable, Not Just Promised

SolanaFlipz uses a cryptographic seed-and-hash system so every round's outcome can be independently verified. Before you bet, we commit to a result; after you bet, you can prove we didn't change it. This applies to all five games: Mines, Crash, Chicken, Case Battles, and Rock Paper Scissors.

Server Seed Commitment

Before each round starts, our server generates a secret seed and shows you its hashed version. This locks in the outcome before you place a bet.

Client Seed Input

You can provide your own client seed (or use a random one we generate) that combines with the server seed to produce the final result — so you have a hand in the randomness.

Reveal & Verify

After the round ends, we reveal the original server seed. You can run it through the verify tool below to confirm the result matches exactly what was promised.

This method is identical across all games; only the inputs differ: grid layout for Mines, multiplier curve for Crash, case odds for Case Battles, and move outcomes for Rock Paper Scissors.

Recomputed outcome hash generated. Compare it with the hash shown in your round details.

Verify Any Round Yourself

Enter the server seed, client seed, and nonce from any completed round to recompute the result and confirm it matches what was shown to you in-game. Find these values in your Transaction History or in the round details of any game you've played.

Fairness, Randomness & Verification: Common Questions

  • Is the game outcome decided before or after I bet?

    Before. The server seed (and its hash) is generated and committed before you place your bet, so the outcome is locked in ahead of time and cannot be changed afterward.

  • Can SolanaFlipz change the result after I play?

    No. Because the hashed server seed is shown to you before the round starts, any attempt to alter the underlying seed afterward would produce a hash that doesn't match, which you can detect using the verify tool.

  • What's the difference between the server seed and client seed?

    The server seed is generated by us and kept secret until after the round; the client seed is yours to set (or randomize). Combining both means neither side alone controls the final result.

  • Does this apply to Case Battles and Rock Paper Scissors too?

    Yes. All five games — Mines, Crash, Chicken, Case Battles, and Rock Paper Scissors — use the same seed-and-hash commitment system, just applied to each game's specific mechanics (grid reveals, multiplier curves, case odds, or move outcomes).

  • Where do I find my seed and nonce to verify a past round?

    Every round's seed values and nonce are logged in your Transaction History page, alongside the deposit or wager details for that round.
