What Does Provably Fair Mean?

“Provably fair” is a method used by some online games to let a player verify that an outcome was not changed after a bet was placed. It usually works with cryptographic values supplied by the game and the player.

What it can help you check

When implemented properly, the system can allow you to verify that the published game result matches the inputs used for that round. It is a transparency feature—not a guarantee of profit or a replacement for choosing a reputable, legally available operator.

Questions to ask

• Is there a clear verification guide?
• Can you change your client seed?
• Does the verification apply to every relevant game?
• Are the game rules and return-to-player information clearly stated?

Understand the game mechanics and set a budget before you play. Random outcomes remain random even when they can be verified.
