Provably Fair System

Our transparent verification system ensures every spin is completely random and cannot be manipulated. All results can be independently verified using cryptographic proof.

How It Works

Understanding Fair Gaming

Item Weighting

Every item has a weight value. Common items have higher weights, rare items have lower weights, creating a balanced distribution.

Seed Generation

We generate a server seed before your spin and show you its hash. Your browser creates a client seed, ensuring randomness from both sides.

Result Calculation

Both seeds are combined using HMAC-SHA256 to generate a random number that determines which item you win.

Verification

After revealing our server seed, anyone can recalculate the result to verify the spin was fair and unmanipulated.

Current Session

Server Seed Hash

SHA-256 Hash

This cryptographic hash proves our server seed was generated before your spin. The actual seed will be revealed when we rotate to a new one, allowing full verification of all spins.

Algorithm Details

// Provably Fair Algorithm Implementation

                1. hmac = HMAC-SHA256(serverSeed, clientSeed + ":" + nonce)

                2. bytes = first 16 characters of hmac

                3. u64 = convert bytes to unsigned 64-bit integer

                4. fraction = u64 / (2^64 - 1)

                5. ticket = floor(fraction × totalWeight)

                6. winner = find item where cumulative weight > ticket

HMAC-SHA256: Cryptographic hash function that combines both seeds securely
Server Seed: Secret random value generated and hashed before each spin session
Client Seed: Random value generated by your browser for additional entropy
Nonce: Counter that increments with each spin in a session
Weight System: Mathematical distribution ensuring advertised odds match actual results
