Crypto Casinos with Provably Fair Games

Concerned about in-game manipulation from shady crypto casinos? That’s where Provably Fair games come to the rescue. The casinos listed below have a specific section where their games are Provably Fair. This means you can manually verify the randomness of the game’s outcome using cryptographic algorithms.

What are Provably Fair Games?

If a game is labelled as “Provably Fair”, it means the casino can let you verify that the result of any round you play was truly random. This is done using cryptographic algorithms that give players complete transparency.

Simply put, the casino provides you with the tools to confirm that the result of each round was generated fairly. The outcome is determined using a combination of inputs which are hashed (encrypted) before the game starts. After the round ends, you can check the data to confirm that nothing was changed or interfered with along the way.

If you’re in any way concerned about your favourite casino “rigging” a game, then stick to Provably Fair games. You can stay rest assured that, even if you lose a particular round, it was down to the genuine odds and randomness of the game as opposed to hidden manipulation.

How does it work? How do I verify that my result was truly random?

Here’s exactly how a Provably Fair game works:

1. Before the round starts, the casino internally generates a server seed. This is kept secret and hidden from you (for the time being).
2. Before you start playing, the casino gives you a hash (string of letters and numbers). Hashes are irreversible, meaning you cannot figure out the server seed from it.
3. You also get to see your client seed and the nonce (round counter).
4. Once you finish playing, win or lose, the site reveals the server seed from earlier.

How to prove the result was truly random:

1. Take the server seed, client seed, and nonce.
2. Run them through the game’s published algorithm (casinos often provide a verification tool directly on their site).
3. If you’re tech-savvy, you can even use a programming language like Python or JavaScript to verify independently.
4. You’ll get the exact same result that was shown in your game, proof that nothing was tampered with.
5. If you’re still not convinced, you can take the server seed, hash it yourself, and match it with your hash from the game.

In a nutshell, the hash proves the server seed wasn’t altered, and the reveal lets you confirm the outcome was generated exactly as promised.

What games tend to be Provably Fair?

Provably Fair games typically include those crypto casino classics that we all know and love: Crash, Plinko, Mines, Dice, HiLo, and Limbo.

Some crypto casinos, like BC.Game, also offer Provably Fair virtual blackjack, roulette, baccarat, and even certain slots!

If you’re unsure if a particular game is provably fair, just scan around the page and look for the label. Trust us: if a casino is offering a Provably Fair game, they’ll be the first to tell you. They have no reason to hide one of the most attractive features they could advertise.

Are the games actually fair?

Well, that depends what you mean by fair!

If by “fair” you mean a game with no house edge, then the answer is no, Provably Fair games are not actually fair in that sense. Make no mistake: they still have a house edge and a return-to-player (RTP) below 100%.

However, provably fair games are fair in a different sense. They are verifiably random, meaning outcomes are mathematically auditable and cannot be manipulated by the casino. The results are locked in before you play, and you can be assured that no funny business is going on, even if the casino still has the edge at the end of the day.
