What Is a Provably Fair Casino?
Provably fair casinos are online gambling providers that offer verifiably random games.
These casinos use cryptographic algorithms to generate random numbers, which ensures that the games cannot be rigged.
Provably fair casinos allow players to verify the fairness of each game using a cryptographic hash function. The house edge (often impressively low) and the RTP are also pre-defined.
Before we dive deeper into what this verification entails, let’s look at provably fair and traditional casinos side-to-side:
| Provably Fair Casinos | Traditional Casinos | |
| Random outcomes? | Yes | Yes |
| Algorithm visible? | Yes | No |
| Randomness verifiable? | Yes, all outcomes are on the public ledger. | No, because the casino algorithm is private. |
| Games available | In-house exclusives like Crash and Plinko | Most online casino games |
| Popularity | Growing | High |
Now that you’ve got a solid idea of the concept of provably fair casinos, let’s move on to what makes them that way – the games!
Provably Fair Casino Games
As crypto gambling grows, so does the interest in provably fair games.
Empowering gamblers
Provably fair means you can check if the game result was random.

How do you the game’s algorithm isn’t rigged to cheat you? The short answer is: you can’t.
As a player, you have no other choice but trust the casino operator.
This is where provably fair games can make a huge difference. With this technology, you have tools to check if the game’s outcome was truly fair. We’ll cover how the checking process works later on.

Random Number Generation: The Key to Provable Fairness
To have a truly fair casino game you need the outcome to be random.
Imagine you’re rolling a dice:
The number you get, 1-6, is completely random. You have a 1:6 chance of getting 1, a 1:6 chance of getting 2, and so forth.
This applies to every roll. Just because you threw a two on the last round doesn’t mean you can’t do it again. The chance remains 1:6 and neither you, nor the casino, knows what the outcome will be.
The physical dice roll is random by design. Unless you use crooked dice, there is no way to manipulate the outcome.
But what about online casinos? How do they decide the outcome of your dice roll?
One thing is for sure – there is no hidden casino employee that rolls a dice every time you play a dice game. Instead, the casino uses a random number generation (RNG) equation to calculate the outcome.
Random number generation (RNG) equations use values of entropy (chaos) like the micro-movements of your mouse to generate a random string of numbers. Blockchain technology offers new ways to ensure RNG. You can learn more about blockchain casino RNG in our dedicated article.
Companies and regulators responsible for licensing casinos evaluate the equipment’s RNG mechanism or the online casino’s server. The difference with provably fair casinos is you, as a player, can also verify the random outcome.
How Does It Work?
As a casino creator, you can build games on top of a blockchain, granting transparency and immutability to the way the game operates. This takes advantage of the distributed ledger technology – the same one that allows you to trust transactions even without a centralized institution:
If the game is not built on the blockchain, it can still be provably fair.
For instance, if the code is open-source, you can proactively check it and make sure there is no manipulation. Verification tools can help you check provable fairness for a specific result.
Here is how that would work:
- You need a random number to determine a game’s outcome.
Whether you’re playing dice, slots, or blackjack, the casino needs a random number to figure out the result of the game. - From the player side, a client seed is generated.
This is the first step of random number generation. Your computer’s hardware generates a client seed. It’s displayed as a hash (e.g.: 4b02asd9l8cocacrl119sp0x33497a) because it’s encrypted against intruders. - The casino generates a server seed.
That comes from the game server side and it’s unique and non-forgeable (thanks to blockchain technology.) - The casino uses the server seed and client seed to generate a random number.
This random number determines the outcome of the game. - Once the game is over, you can see your client seed.
Now that you know your seed, you can use that to figure out the server seed. - You can input the seed in a calculator and it should return a hash.
There is only one possible hash, based on your client seed. If it matches the server seed hash, the game wasn’t rigged. Any changes mid-game would result in the hashes not matching.
How Do I Verify Game Outcomes?
Most casinos with provably fair games have their own verification methods and tutorials. At their core, they boil down to checking the randomness for yourself. But how exactly do you do that? We’ll show you:
First, we should make the distinction between crypto casinos and blockchain casinos:
Cryptocurrency casinos accept crypto as a method of payment. We’ve talked about the best Bitcoin casinos, top Ethereum sites, and other altcoins extensively throughout our reviews.
Blockchain casinos are based on blockchain technology. Usually, these are Dapps (decentralized apps).
FYI: Just because a casino accepts Bitcoin, it doesn’t automatically mean it uses blockchain technology in its games.
For example, you can gamble with 65+ cryptos at BC.Game and they don’t take fiat payments. However, the casino is still not built on the blockchain – it’s a crypto casino, not a blockchain one.
Now here’s the catch:
Both blockchain and non-blockchain casinos can be provably fair.
The difference is how you check provable fairness. If the casino and its games are assembled with blockchain technology, they can be provably fair by design. On the other hand, you can verify the randomness with non-blockchain casinos by checking the specific round.
How does that work? Here’s a step-by-step:
Provably Fair Games That Are Not On The Blockchain
Provably fair verification processes can vary across casinos.
Let’s check out a simple example – BC.Game’s Classic Dice:
The classic dice game results are calculated like this:
- BC.Game uses the client seed and server seed to calculate a hash.
This gives them a 64-character string in hexadecimals. - They take eight characters of the string and convert it into an int32 value.
An int32 value means they have 32 bits to store the number. - Then, BC.Game modifies the number.
They divide the value by 0x100000000, multiply it by 10001 and divide it by 100. - This returns a dice number which determines the game outcome.
In short, BC.Game takes two random numbers, runs them through an algorithm, and returns a new number, which determines the game outcome.
To verify the fairness when you’re playing dice, first find the seed:
Then, go ahead and copy the numbers from the popup (we can’t exactly show you ours – that wouldn’t be safe).
Go to the side menu and find the provable fairness section. You’ll get the link to the provable fairness validator there:
Finally, go to the provable fairness validator and paste the seed. The program will repeat the calculations and reveal the result – if the outcome matches your original game, the dice was provably fair:
And there you have it, this is how you check provable fairness on a non-blockchain casino. Keep in mind that every provably fair casino will have a slightly different way of doing this. What brings them together, though, is the fact you can always make sure the outcome was fair.
Blockchain Games
If a casino game is blockchain-based, the verification process takes a big turn toward simplicity. Taking advantage of smart contracts in platforms like Ethereum, TRON, EOS, or NEO to build casino games means the rules will all be governed by an overseeable code.
That code – along with any transactions carried out on the blockchain – can be publicly audited in a more robust manner.
Instead of the player manually checking each round, the software can be audited once to ensure no form of foul play will occur. Periodical checks can then be performed to confirm the code has not been altered. This is a big win for players, and regulators as well.

Final Thoughts
Provably fair games give you additional peace of mind. You can check the game’s fairness at any time, and be confident that the game is fair.
But some of these casino games require a little bit more work on your part. You usually need to take some time to understand how the game works – and to check the hashes yourself.
Reputable casinos like Stake, BC.Game, and Cloudbet are very transparent about the process. For the most part, you don’t have to manually check everything – but you can, if you want to.
Alternatively, you could go to a casino Dapp like Earnbet, which is provably fair by design.
In the end, provably fair games are a great way to play casino games online. They’re fair, transparent, and you can always check the game’s integrity for yourself.
