What does "Provably Fair" mean?

Provably fair is a system in crypto gambling that allows anyone to independently verify that game outcomes are not manipulated. This is achieved using cryptographic algorithms, ensuring transparency for every result.

How does Provably Fair technology work?

Provably fair games use a combination of server and client seeds, plus a nonce, to determine outcomes:

How it works (step-by-step)

  1. The casino generates a server seed and publishes its hash.
  2. The player provides a client seed (either random or custom).
  3. Server seed, client seed, and a nonce are combined to generate the game result.
  4. After the game, the server seed is revealed so anyone can verify the outcome.

"It's like rolling dice in public, recording the math, and letting anyone double-check it later."

Why is Provably Fair important?

  • Cheating is virtually impossible
  • Players can trust the results
  • Many top crypto casinos offer provably fair games

Which games support provably fair?

Common examples include slots, roulette, dice, blackjack, crash games, baccarat, Plinko, and Mines.

FAQ

Are provably fair games always 100% fair?

They guarantee transparency via cryptographic hashing, but don't guarantee 100% perfect randomness beyond algorithmic integrity.

Can provably fair systems be hacked?

Due to SHA-256 hashing, it's extremely difficult - current technology makes manipulation nearly impossible.
