What is Provably Fair?

The complete guide to understanding provably fair technology in crypto casinos

The Problem with Traditional Casinos

In traditional online casinos, you have to trust that the casino is being fair. You can't verify if the dice roll, card shuffle, or slot spin was truly random. The casino could manipulate results, and you'd never know.

Provably fair technology solves this problem using cryptographic hashing. It allows you to mathematically verify that every game result was fair and not manipulated.

How Provably Fair Works

1. Server Seed Generated

Casino generates a random server seed and creates a SHA-256 hash. The hash is shown to you BEFORE you bet.

2. You Choose Client Seed

You provide your own random client seed. This ensures the casino cannot manipulate the outcome.

3. Game Result Calculated

Server seed + Client seed + Nonce are combined and hashed to generate the game result. Pure mathematics.

4. Verify Anytime

After the bet, the server seed is revealed. You can verify the hash matches and the result is fair.

Real Example: Crash Game

Server Seed Hash (shown before bet):
a3f5b2c8d9e1f4a7b6c5d8e9f1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0
Your Client Seed:
my-lucky-seed-12345
Nonce:
1
Result:
2.47x Crash Point

After the game, the server seed is revealed. You can verify the hash matches and recalculate the result yourself!
