What Are Provably Fair Games? Everything You Need to Know

You’ve likely heard about provably fair games, specifically when discussing online casino games available at crypto casinos like EVO.io.

But have you ever questioned what it means and exactly how you can test a game to prove the fairness of your online gambling session?

In this article, we look at provably fair games and explain precisely what they mean for you and what you need to do to put this claim to the test.

Read on to discover everything you need to know about provably fair gaming right here at EVO.io.

Understanding provably fair games

The term “provably fair” in online games means that the outcome of the games can be verified by players. This gives you peace of mind that the results of all your gaming sessions are entirely fair and random and not manipulated in any way by developers or operators.

This verification is possible through cryptographic algorithms and blockchain technology, which provide transparency to help build trust in the fairness of games and the gambling industry.

This is why, at EVO.io, we’re passionate about blockchain technology and the confidence it provides to all users.

Provably fair games differ from traditional online games primarily due to this transparency. They put players in control as you can verify any game outcomes to ensure your session is fair.

In contrast, traditional online casino games rely on the game’s internal algorithms and RNG technology to ensure fairness. This means that you, as a player, must depend on the trustworthiness of operators.

While reputable casinos are plentiful and regularly audited, provably fair games offer an additional layer of trust by allowing you to test and independently verify the fairness of each game result. 

How provably fair games work

As mentioned, blockchain and cryptographic algorithms are the underlying technology behind provably fair games. The same principles are used for Bitcoin and other cryptocurrencies.

The blockchain provides a decentralized and transparent ledger where game outcomes are recorded and verifiable.

Cryptographic algorithms generate random numbers and mathematical proofs that you can use to verify the fairness of each game result. 

There is a three-step verification process in provably fair games that typically involves the following steps:

  1. Server seed disclosure: Once the game round concludes, the casino provides the game server seed, unique to that particular game round, and a random number generated by the casino server.
  2. Client seed: A client seed is generated on the player or client side. You can choose your own seed, which will be combined with the client seed to verify the fairness of the round outcome.
  3. Verification: Next, you use a cryptographic hash function to create a unique, fixed string “hash” from the server seed, client seed, and nonce, which is like a unique fingerprint that ensures the game outcome hasn’t been tampered with. If the hashes match, then you know the game result is verified as fair.

If this all sounds complicated, don’t panic! You can use independent third-party software to verify fair game outcomes, and you don’t require any technical knowledge. Below, we will look at the various verification methods available to you.

Verification methods

Verification lies at the heart of provably fair gaming and allows you to determine the fairness of a game round. Below, we take you through the step-by-step process of verifying your game fairness using the provided game server seed and your client seed:

  1. Choose your game

    Head to the EVO.io casino lobby and search for a title. At this stage, only some of our games embrace this technology, but we stock several titles from certain providers like BGaming, which are leading the way in this exciting space.

  2. Server seed hash

    You can view the hashed server seed before playing. This hash is recorded on the blockchain to ensure the seed is committed and cannot be tampered with or changed after the game. You will use the hash for verification.

  3. Generate your client seed

    Use the game controls to select your unique number string. This number should be random, and it will be used in conjunction with the client seed to verify fair play.

  4. Play your game round

    Now that you have these unique numbers, you can take a shot at the game, whether hitting the spin button to spin the reels of a slot machine, dealing blackjack cards, or launching a crash game. Make a note of the result.

  5. Game outcome

    After each game round concludes, the game will reveal the unique server seed that generated the result. This unique number is critical for the verification process.

  6. Hashing & verification

    Once you have received the disclosed server seed, use this in combination with your client seed and nonce to recreate the combined string. A cryptographic algorithm produces a hash, which can be compared to the one provided at the start of the game round.

    If these match up, you know the fairness has been proven, and the outcome has not been manipulated. This process can be facilitated by in-built casino tools or independent third-party services.

Several third-party verification websites, such as Provably.com and ProvFair, can be used for this verification process to ensure you are getting completely honest and transparent results.

Benefits of provably fair games

In the same way that the broader cryptocurrency and blockchain movement is all about transparency, provably fair online casino games use the same technology to ensure fair gaming for all players.

This enhanced security and protection against fraud or tampering ensures a safe and fair environment for players. In addition, the transparency of these games can attract a broader audience to online crypto casinos as players are more likely to engage with platforms they can trust.

What’s crucial about provably fair games is that they help protect players and make you feel safe while playing online casino games. You can independently verify this transparency using third-party tools and software, so you can rest assured that you are protected.

Common types of provably fair games

Provably fair gaming is becoming increasingly common and available across various popular casino games, from traditional titles like dice and roulette to the latest, innovative video slots and exciting crash games.

Online slot machines are the backbone of the online casino industry, allowing game developers to flex their creativity with increasingly more exciting game mechanics, bonus features, and themes.

We have several provably fair slots available in the EVO.io lobby from big-name providers like BGaming that use these cryptographic techniques to ensure game-round outcomes are entirely fair and transparent.

A fantastic example of a slot using a provably fair system that is easy to follow is Aztec Magic, a classic 5×3 slot machine that offers an inbuilt verification function. To test the process, click on the link to launch the title.

You will see a certificate icon in the top right corner. When clicked, it will reveal the server seed hash and the toggles to set your client seed for the reels.

Once you have chosen your unique seed number and wager, hit the spin button to start the round. When the reels stop spinning, the server seed and hashed results will be revealed for you to compare.

You can also copy the result and paste it into a third-party website to confirm that the verification is accurate. This process can be repeated for every spin of the reels, each time creating unique, verifiable results.

Lucky Lady’s Clover is another popular example of the provably fair slots being produced by BGaming. A classic Irish-themed slot game with up to 9 variable paylines and a jackpot prize of 10,000 times your bet.

The title offers many bonus features and provides an easy-to-use interface for verifying the results of your gaming session.

Frequently asked questions

What is a provably fair algorithm?

A provably fair algorithm is a cryptographic method game developers and online casino operators use to ensure and verify the fairness and randomness of online casino game outcomes. The algorithm combines the casino’s server seed, the player’s client seed, and a unique number called a nonce to generate outcomes.

This algorithm allows you to independently verify that your game’s results are random and have not been tampered with by developers or casino operators. To confirm fairness, you can compare the hashed server seed with the one provided by the casino using specialist third-party verification software.

What are fair or unfair games?

Fair games have entirely random and fair game outcomes that developers or casino operators cannot manipulate. They ensure that every player has an equal chance of winning based on the game’s inherent probabilities.

By contrast, unfair games do not offer any transparency and can or have been manipulated to create predetermined results that favor the operator. These games often rely on unverified or questionable algorithms that cannot be verified and are likely not subjected to regular audits.
