What Is Provably Fair Gaming in Online Casinos? A Beginner’s Guide

For players to enjoy online casinos, they need to trust in their fairness. In traditional online gambling, this means playing in licensed casinos that host games from reputable providers.

However, today, with the rise of crypto gambling, transparency has become more direct. Instead of relying solely on regulators and third-party auditors, players can now verify the fairness of each game themselves. This can be done using provably fair systems, a feature available in many Texas online gaming platforms that support crypto.

In this guide, we’ll explain what provably fair gaming is and how it works. You’ll also learn how to use it to check the fairness and security measures of a game.

What Is Provably Fair?

Provably fair is a system that gives players access to data that they can use to verify the fairness of a game. It uses cryptographic algorithms to generate results, ensuring:

• Outcomes are random
• Game results are independently verifiable
• Players can access all data used to generate the outcome

In short, the outcome of every bet comes with a “receipt” detailing how it was calculated. This means that users can reverse calculate and compare the result to the original values to spot any outcome manipulations.

This isn’t possible in traditional online casinos that rely on RNGs, which are closed systems. Their fairness can only be verified by licensing bodies and third-party testing labs, for example, eCOGRA.

How Do Provably Fair Systems Work?

Provably fair systems are based on 3 components that work together:

• Player seed: A random string of numbers, letters, or characters that the player generates by placing a bet. You can input your own player seed or let the game generate one.
• Server seed: A value created by the casino server before the round starts. It’s hidden from the player to prevent them from manipulating the outcome.
• Nonce: A variable that increases with every bet you place to ensure the same seeds produce different results for each round.

The server generates its seed at the start of the round and turns it into a string of characters through a process called hashing. It then shares the hashed value with the player and keeps the original seed secret until the round ends.

When a bet is placed, the system uses the player seed, server seed, and the nonce to generate a combined seed and determine the outcome.

The original server seed is revealed to the player at the end of the round. They can use it in two ways:

• Confirm whether the server seed was changed after the game started: This involves hashing the original server seed and comparing it to the hash received before the game started.
• Verify the fairness of the outcome: This involves combining the server seed, the player seed, and the nonce to reproduce the game results. If the results match, it means they were generated fairly.

The verification process can take less than 10 seconds. You can use online hash calculators, provably fair verification pages, or a casino’s tool, if available.

Can Provably Fair Systems Be Hacked?

Provably fair systems cannot be hacked due to the security measures of the player and server seeds. The server seed is secured using the SHA-256 algorithm, which is impossible to reverse-engineer to reveal the original seed. Only a future quantum computer might decrypt it, but that’s decades away.

What’s more, licensed online casinos implement strict data protection measures to safeguard player seeds from unauthorized access and manipulation.
