Provably Fair Aviator Calculator

Verify the fairness of Aviator game results using cryptographic algorithms


How Provably Fair Works

The game uses a combination of server seed, client seed, and nonce to generate a cryptographically verifiable random number that determines the crash multiplier. You can verify any round’s fairness by recreating the calculation.

Verification Steps

Algorithm Explanation:

  1. Combine Seeds: Concatenate serverSeed + clientSeed + nonce
  2. Generate Hash: Create SHA256 hash of the combined string
  3. Extract Hex: Take the first 8 characters of the hash
  4. Convert to Decimal: Convert hex to decimal (0 to 4,294,967,295)
  5. Apply House Edge: Multiply by 0.99 (1% house edge)
  6. Calculate Multiplier: Use formula: (2^32 / decimal) * houseEdge
  7. Format Result: Round to 2 decimal places with minimum 1.00x
⚠️ Important: This calculator is for educational purposes to understand provably fair algorithms. Different platforms may use variations of this algorithm. Always verify the specific implementation used by your chosen platform.

About Provably Fair Gaming

Provably fair gaming uses cryptographic methods to ensure that game outcomes are genuinely random and cannot be manipulated by the house. The system works by:

  • Server Seed: A secret random value generated by the server (revealed after the game)
  • Client Seed: A value you can set or verify to influence the outcome
  • Nonce: A counter that increments with each game round
  • Hash Function: SHA256 ensures the process is deterministic and verifiable
💡 Pro Tip: You can change your client seed before each game to influence the randomness. Some platforms allow you to set a custom client seed to ensure you’re getting truly random results.
