Online gaming has always faced one major question: Can players trust the results? Every game of chance, from gaming machines to case battles, comes with scepticism. Some believe the system is rigged, while others question whether operators manipulate the odds. Legitimate gaming platforms operate within strict regulations. They do undergo periodical audits – but these checks happen behind the scenes, leaving room for doubt.
To combat this scepticism, gaming platforms created the “provably fair” system. It is a method that allows players to verify game results themselves, ensuring complete transparency. Unlike traditional audits, this system offers real-time proof that every outcome is fair and unmanipulated.
What Is Provably Fair?
Provably fair is a system built on cryptographic principles that ensures game results are truly random and not influenced by the operator. It uses hashing algorithms and, in many cases, blockchain technology to generate results in a way that neither the player nor the operator can alter. This system leverages cryptography to provide verifiable randomness, allowing players to independently confirm the integrity of each game.

How Provably Fair Works: A Technical Deep Dive
Let’s dissect the technical mechanics of a typical provably fair system:
1. Random Seed Generation:
The process begins with the generation of random “seeds.” The operator provides a server seed (a secret random number), and the player contributes a client seed. This combination adds an extra layer of unpredictability and player involvement. The server seed is often generated using a cryptographically secure pseudo-random number generator (CSPRNG).
CSPRNGs are designed to produce sequences of numbers that appear random but are actually generated by a deterministic algorithm. The cryptographic nature ensures that even knowing a portion of the sequence doesn’t allow prediction of future numbers.
2. Hashing for Security:
The server seed is then passed through a cryptographic hash function. A hash function is a one-way algorithm that takes an input (the server seed) and produces a fixed-size string of characters (the hash). Crucially, it’s computationally infeasible to reverse the process – you can’t get the original server seed back from its hash. This is a critical security feature.
Commonly used hashing algorithms include SHA-256, SHA-384, and SHA-512. These algorithms take the input and perform a series of bitwise operations, logical shifts, and modular arithmetic to create a unique fingerprint of the data. The hashed server seed is then displayed to the player before the game starts. This acts as a digital commitment; the operator is bound to the original server seed. (See Figure 1)
Result Calculation: The actual game outcome is determined using both the server seed and the client seed. The exact method can vary, but the important point is that both seeds play a role. A common approach is to combine the seeds (perhaps by concatenating them) and then use this combined value as input to a PRNG. The output of the PRNG, after some transformations, determines the game result.
The specific algorithm used is usually publicly documented by the platform. For example, the combined seed might be used to seed the PRNG, and the first few numbers generated by the PRNG could then be used to determine the outcome of a card game or a dice roll.
Verification: After the game concludes, the platform reveals the original, unhashed server seed. The player can then independently hash this revealed server seed using the same algorithm (e.g., SHA-256) that the platform used. If the resulting hash matches the hash that was displayed before the game, the player has mathematical proof that the server seed was not altered, and therefore, the game result was verifiably fair. Online tools and even simple command-line utilities can be used to perform this hashing calculation.
A Real-World Example: CSGORoll’s Provably Fair System
CSGORoll, a platform known for its case openings and games, is a well-known example of a platform employing provably fair technology. While the specifics of their implementation may vary, the general principles align with the technical details described above. Here’s a breakdown of how a user might interact with their system (or a conceptually similar system):
- Server Seed Hash Display: Before a game round starts, the platform displays the SHA-256 hash of the server seed. This hash commits the platform to a specific server seed for that round.
- Client Seed Input: The user provides a client seed. This can either be a user-provided seed or one generated by the platform.
- Game Outcome and Reveal: The game proceeds, and the outcome is determined using the server seed and client seed. After the game, the platform reveals the original, unhashed server seed.
- Verification: The user can then take the revealed server seed and use a SHA-256 hashing tool to calculate the hash. If this calculated hash matches the hash that was displayed at the start of the game, the user can verify that the server seed was not changed, proving the fairness of the game.
How Does It Compare to Traditional Audits?
Most licensed gaming platforms undergo third-party audits. Independent organizations check game fairness, random number generators (RNGs), and payout rates. While these audits add credibility, they come with limitations:
- Lack of real-time verification: Players must trust that past audits still reflect current operations.
- Dependence on external regulators: If an operator manipulates the system between audits, players would never know.
- Opaque processes: Audit results are often not publicly available, leaving players in the dark.
Provably fair gaming eliminates these concerns by offering instant verification. Instead of waiting for an external audit, players can check fairness on their own, whenever they want.

Why More Platforms Are Adopting Provably Fair Systems
Transparency is becoming a major selling point in online gaming. Players demand more control and visibility. The platforms that embrace provably fair systems gain a competitive edge. The ability to verify each game’s fairness builds trust, credibility, and loyalty—all key factors in the iGaming industry.
This shift also challenges traditional game operators to rethink their approach. With provably fair games becoming more common, will regulated gaming sites eventually adopt similar transparency measures? Or will players start favouring platforms that allow them to see fairness in action?
The future of online gaming is moving toward openness and accountability—and provably fair technology is leading the way. Further advancements like verifiable random functions (VRFs), which cryptographically prove that a random value was generated fairly, promise even greater levels of security and trust in the future.
