Provably Fair

Skip To The List of Casinos

"Provably Fair" is a term originating from, and directly related to the iGaming industry and online gambling in general. In order to fully comprehend the need for a fairness guarantee in the context of real-money, internet wagering, as well as appreciate its existance in the first place, we must ask ourselves this:

What is my MAIN concern as an online casino player? 

Provably Fair

To avoid getting conned by sham operators offering fake games I cannot possibly benefit from. Sounds simple enough, but the matter is more complicated than it seems and requires an across-the-board solution that will be adopted by the majority of brands in the industry. 

No matter how popular or reputable a site can be, there is an overarching issue of trust between operators and players. No wonder!

If You Can't See It...

Are the results we get while playing games, such as slots or card games, truly random? Since gambling is based on luck and chance, there is always fear that a product has been tampered with, intentionally altered to make players lose. Gambling on the internet is always riskier than going to a well-known land based casino where you are physically present at a location where games take place.

With iGames, players can't see the card being shuffled, or how the mathematics of slots actually work. Addressing customer's concerns, reputable casinos use third-party testing laboratories to audit and verify that the Random Number Generator - a computer program that produces the outcomes of games, really IS fair. The certificate is then used as proof that their software is indeed fair and safe to use: eCOGRA, TSTGLI and others.

However:

Players still have to put their faith into these labs, and trust they are doing a proper job. But, is this really the best we can hope for as far as our safety, hard-earned funds and sanity go? Luckily - NO! 

'Nothing in life is guaranteed except change.' And random game outcomes - we'd like to add - the ones we can see with our own eyes, and more importantly...

...prove beyond a doubt using our own wits! 

Ensure Fair Play

With the Provably Fair system, third-party certificates have been made obsolete, and that is why brands that have in place do not usually need the services of independent testing labs.

Instead:

Players themselves can verify the outcomes in real time, after they have finished the gameplay, using tools provided by the operator.

What is the single most important advantage of this method?

It is almost a 100% certain to be correct in its evaluations! How? 

Because it is based on an algorithm with hash functions that verify the outcome of a game based on the events that took place WHILE playing it. Having such a tool at our disposal gives us more confidence, and provides a chance to expose rogue outlets on our own, should we encounter any irregularities. It adds to the transparency of truly honest venues, who care about their reputation and the safety of their customers.

Origins & Function

Provably Fair first appeared in the Bitcoin casino community, and has been gaining in popularity since 2012. The method has not yet become a standard practice in the global industry, even though it is perfectly fit for any casino - crypto and fiat currency alike. Hopefully...

...this will change in the near future (pushed by the proliferation of black market, illegal operators and software pirates), and the system will receive a wider recognition and acceptance. One of the likely reasons why some respectable brands are reluctant to implement it, is because many players have trouble understanding HOW it works, and WHY it should be used to their benefit.

The Provably Fair system is a mathematical method that is used to ensure that no one, neither players nor casinos, can know the result of the game before it starts and that the casino cannot tamper with the random operation of the game.

It is essentially a cryptographic hash function, a one-way algorithm implemented to make sure neither casino nor the player can possibly figure out the final shuffle of the deck before the game starts, or before it has actually been dealt. The same principle applies for randomly generated slot spins. 

Methods most commonly used are:

  1. Fisher Yate's Shuffle - to generate the shuffled deck, and
  2. Mersenne Twister algorithm - to generate random numbers for the former to use.

The casino then uses an algorithm with a random number generator, to create new decks and shuffles, seeded with an encrypted hash combining two variables:

  1. the server seed 
  2. the client seed.

Often referred to as a digital fingerprint, the hash of the server seed is received in advance, and plus it is encrypted, so players know the site can't change it retroactively, and they can't calculate their won results in advance and hit a sure win either.

Simply put - the player takes part in generating a random game result, NOT the casino alone. Before placing any bets or spinning reels...

 

  • The casino and the player generate random numbers: a server seed and a client seed
  • The player can't see the casino seed in order to prevent them from controling the game; instead the casino sends them a hash of its server seed
  • The player will be able to see the server seed after betting has already taken place
  • Now the player can combine their client seed and the revealed server seed to verify the fairness of the result
  • If the same result has been generated, that means the casino did not temper with it before the bets were made

Provably Fair Software

While the software technology is still predominantly utilized by casinos themselves regardless of who supplies their platform, software providers are getting increasingly interested in the system and some have even implemented it into their portfolios.

One such provider is SOFTSWISS, game developer and white label products supplier - one of the first companies to develop a BTC casino solution, which rebranded to BGaming in 2018.

Their games are verifiably fair and offer a provability widget on the right side of the screen, to be used by players at their leisure.

Another reputable operator and proprietary software developer is Slotland Entertainment, the owner of Slotland, Win A Day and CryptoSlots Casino, the last of which features a fully verifiable platform of video slots and video poker games with Provably Fair results.

Their PF technology guarantees at least one winning spin within the random set of nine possible results, generated randomly by the casino server before a player hits the spin button. 

Once finished, players can check the results in the game menu, with the chosen result highlighted among the remaining potential outcomes. 

To make the PF concept easier to understand, LCB did an extensive interview with long-term Slotland rep Jack Jelinek, who kindly explained in great detail the what's and why's of ''the technology and a cryptocurrency-only casino that go the extra mile in guaranteeing fairness.''

Below is a list of Provably Fair casinos, which is regularly updated with latest additions. At the moment, the vast majority of online brands that offer this method is also BTC and cryptocurrency-oriented in general. If you are looking to minimize risks and boost safety in your gaming adventures, these types of internet venues are your best bet and the highest fairness guarantee you can get in the current iGaming climate.
