What Is Provably Fair?

Provably fair in slots is a cryptographic method that lets players verify that a game round was not manipulated. The term describes a way to check a round’s integrity; it does not, by itself, provide information about a slot’s RTP, paytable or potential results.

What is Provably Fair?

Provably Fair means that a cryptographic method is used to let players verify that a game round was not manipulated. This is the provably fair meaning relevant to slots: the focus is on checking a round, not on predicting what it will produce.

The term does not tell you a game’s RTP, volatility, maximum win or other slot specifications. Those are separate details to check in the game information.

Simple example

Imagine a player wants to check whether a particular round was manipulated. A Provably Fair method is intended to let the player verify that the round was not manipulated. That is the core idea; no specific game, verification steps or example result are provided here.

Common misconceptions

It guarantees a particular result: The definition is about verifying that a round was not manipulated, not about guaranteeing a result.
It gives the game’s RTP: RTP is a separate specification and is not included in the definition.
It explains the paytable: A paytable is not described by the term itself.

How Provably Fair works

At a high level, Provably Fair uses cryptography to let players verify that a game round was not manipulated. The exact verification process can vary, but no particular process or set of steps is specified here. Check the relevant game information for details of how verification is available.

A verification method concerns the integrity of a round. It does not replace the game’s other information, such as its paytable or RTP. If an RTP figure is not listed, check the in-game information screen; RTP can differ between casino versions.
