Provably Fair Verified
Mines Cryptographic Grid Verification
Verify the exact location of every mine mathematically using seed history.
Technical Framework Overview
In Mines, the position of all mines on the 5x5 grid is determined before you make your first selection. This is done by initializing a random number generator with combined server and client seeds, then permuting the grid using a deterministic algorithm.
1. The Permutation Protocol
The 25 grid slots are indexed from 0 to 24. A sequence of random numbers is generated from the combined seed using a secure hash chain.
2. Fisher-Yates Grid Shuffling
To ensure unbiased placement, the system shuffles the grid using the Fisher-Yates algorithm, driven by the seed bytes.
>An array of 25 items (representing empty slots and mines) is initialized.
>For each index, a seed-derived random float determines the swap coordinate, generating a completely unbiased layout.
Establish Winning Probabilities
Since mine layouts are mathematically locked, you can calculate the exact probability of hitting a mine at every step. Use our EV Calculator to manage risk dynamically.
