What are probably fair casinos?

Provably fair casinos employ cryptographic techniques that enable players to verify the fairness of game results themselves. This system is mainly implemented in online gambling platforms that use cryptocurrency.

Probably fair systems are implemented mostly in crypto casinos.

How provably fair works

Provably fair systems mostly operate on:

  • A server seed that the casino generates
  • A client seed that the player selects
  • A cryptographic algorithm that yields the game result

Players can check the game outcome’s integrity by seeing the math proof after a round of the game.

Benefits of provably fair systems

  • More transparency
  • Less dependence on trust
  • Outcomes that can be verified

These systems have a wide appeal among bitcoin and ethereum casinos that want to provide proof of their fairness besides just relying on third-party verification.

Limitations to consider

The use of a provably fair system does not guarantee the player will win or that the player is free from the risk of gambling. Such a system only confirms that the results of a game are not altered after the placing of bets.
The players, however, should also be diligent in checking the terms as well as payout structures and should always consider responsible ​‍​‌‍​‍‌​‍​‌‍​‍‌gambling.
