Provably Fair casino games let you verify the fairness of each round yourself. You can confirm that the casino didn’t tamper with the results, which means you don’t need to trust a third-party auditor.
We’ll explain how Provably Fair crypto gambling games work. You’ll discover which games use this technology, and we’ll show you how to verify a Provably Fair bet.
What Does Provably Fair Mean?
Provably Fair is a system that lets players audit certain casino games. These Provably Fair games use cryptographic hashing algorithms, most commonly SHA-256, to lock in each result before you place your bet.
The crypto casino publishes a scrambled fingerprint of its secret data in advance, and you can later check that fingerprint to confirm that nothing was changed. If the casino altered even a single character, the fingerprint wouldn’t match, and the tampering would be exposed.
This means you don’t simply need to trust the casino to host fair games. You audit the games yourself, so you can personally confirm that the games aren’t rigged.

Provably Fair games use three inputs: a server seed, a client seed, and a nonce (number used once). These three inputs combine to produce the results, and you can use them to check that the outcomes were fair.
Server Seed
The casino creates a server seed before you play. It’s a long, random string of characters. You’ll only see a hashed version of the server seed, but it’s irreversible, so the casino can’t alter it later without being caught. It’s like a sealed envelope, which you can open after playing.
Client Seed
You contribute this string of characters, which ensures the casino isn’t fully in control of the results. Your browser will generate a client seed for you, but you can create your own if you prefer. The casino will combine the server seed and the client seed to deliver the results.
Nonce
The nonce is simply a counter that increments after each bet. It typically starts at 0 or 1 and increases by 1 after each round. This means you can use the same seed pair (server seed and client seed) across multiple rounds, since the nonce produces a different result each time.
Reveal and Verify
After the round ends, you can reveal the unhashed server seed. If you plug that into a verifier along with the client seed and the nonce, you can verify that the outcomes match. This lets you prove the site didn’t manipulate the results. If the outcomes differ, contact the customer support team to file a complaint and consider switching to a different casino.
How to Verify a Provably Fair Bet
Verifying the results of Provably Fair casino games is easy. Follow five simple steps to confirm the results weren’t rigged:
Save the server seed hash. Crypto casinos display a hashed version of the server seed before you play. You’ll typically find it by selecting the “Provably Fair” or “Fairness” button. Find the seed and save it before playing.
Place your bet. Choose your stake and play the game. Remember that the nonce increases by 1 with every round – each ball you drop when playing Plinko, each time the vehicle takes off in a crash game, and so on.
Rotate your seed pair. The casino will reveal the unhashed seed once it’s no longer in use. Return to the fairness menu and request a new seed pair. The casino will then reveal the old server seed, which will be unhashed.
Check that the hash matches. You can then enter the unhashed server seed into a SHA-256 calculator. There will be one on the site, or you can use an independent one online if you prefer. Compare the output with the hash you saved in Step 1. If the results match, you’ve confirmed that the casino committed to the seed before you played.
Recalculate the result. Enter the server seed, client seed, and nonce into the verifier. The recalculated outcome should be identical to the result you saw in-game. If so, you’ve proved that the result was fair. If not, the casino manipulated the result.
Which Games Are Provably Fair?
Games like Mines, Dice, and Plinko are Provably Fair at most crypto casinos. You’ll also find a handful of slots and table games that use this technology. These are the top five crypto casino games to play if you want to personally verify the fairness:
Crash: A plane or a rocket flies across the screen, and your profit increases with each passing second. The aim is to cash out before the vehicle crashes. Some modern crash games use hot-air balloons, footballs, and other objects, but the mechanics remain the same.
Plinko: Drop balls into a board, and they will make plinking sounds as they bounce off various pegs. The balls will eventually land in one of the slots at the bottom of the screen. Each slot has a multiplier that determines your payout.
Mines: Simple Minesweeper-style games, which invite you to reveal tiles on a grid. If you reveal a gem, your profit will increase. You can cash out at any time, but if you reveal a mine, the round ends and you lose your stake.
Dice: Choose a target number, often from 0-99 or 0-9,999, and then bet on whether the dice roll lands over or under that target. Choosing your own target lets you control the volatility. For example, you can choose a low number and bet on “over” to boost your chances of winning, but that will result in a smaller profit than betting “over” on a high number.
Keno: Pick up to 10 numbers on a grid and watch as the game draws winning numbers at random. Your payout will depend on how many matching numbers you picked when playing this popular lotto game.
Other options include Boxes, Chicken Crossing, Wheel, Diamonds, Tower, and Rock, Paper, Scissors. Thetop crypto casinos release their own versions of these games. Head to the site’s “Originals” section to find them.
Some software providers, including Spribe and BGaming, also use Provably Fair technology to power their instant-win games. Popular examples include Aviator by Spribe and Plinko XY by BGaming.
It’s rare to find Provably Faironline slots and table games. However, BGaming is a pioneer in this field. The studio has released several Provably Fair table games, including blackjack and roulette, plus Provably Fair slots like Avalon: Lost Kingdom. Some crypto casinos also release their own Provably Fair blackjack, roulette, and video poker games. You won’t find any Provably Fair live dealer games.
Provably Fair vs RNG Audits
Most casino games don’t use Provably Fair technology. The software providers work with independent testing labs like eCOGRA, BMM Testlabs, iTech Labs, and Gaming Labs International (GLI) instead.
These independent auditors test and certify the games for fairness and accuracy. They make sure the Random Number Generators (RNG) powering the games are working correctly, and they ensure the results are in line with each game’s stated return to player (RTP) rate.
Companies like GLI and eCOGRA are highly respected, but you still need to rely on the testing labs to do their jobs properly. That’s not the case if you play Provably Fair crypto gambling games. You become the auditor.
The Limits of Provably Fair
Provably Fair technology lets you verify the fairness of the game results, but it doesn’t guarantee that the casino is safe and legit. For example, a crypto casino could host Provably Fair games but also run bait-and-switch bonus scams or refuse to pay winning customers. That’s why it’s important to stick to the trusted, reputable casinos recommended by our experts.
The technology doesn’t remove the house edge on casino games either. You can confirm the casino didn’t tamper with the results, but the site still has a mathematical advantage. Choose games with high RTP rates to improve your theoretical returns. For example, Plinko by BGaming has a 99% RTP, which equates to a slim 1% house edge.
As mentioned above, only a small percentage of crypto casino games are Provably Fair. You also need to take the time to verify the results. If nobody ever bothered, the casinos wouldn’t actually be accountable. It’s important to check the hash before playing, as you can then prove the casino locked in the results in advance, so make checking the fairness panel a habit.
Provably Fair and Private Play
Provably Fair games are popular atno-KYC casinos. These sites are often lightly regulated or unregulated, which allows them to offeranonymous play. You can often sign up, deposit, play games, and make modest withdrawals without uploading proof of ID.
The trade-off is that these sites don’t operate under strict regulations. That’s where Provably Fair games come in. You don’t need to worry about regulators checking the games, as you can independently verify the results. That’s whydecentralized casinos typically feature Provably Fair games.
FAQs
How does Provably Fair work?
Provably Fair games determine each result by combining a server seed from the casino with a client seed that you control. The casino publishes a hashed version of its seed before you bet, so once the seed is revealed, you can verify the results weren’t manipulated. This means you can personally audit each game round.
Can a Provably Fair casino cheat?
Not without being caught. The pre-committed hash locks the casino into its server seed before you place a bet, so any tampering produces a mismatch that you can easily detect. However, it’s important to check that the hash is displayed before playing, as the guarantee only covers results generated after the commitment.
Are Provably Fair games rigged against players?
No, Provably Fair games aren’t rigged, as you can personally confirm that the results weren’t manipulated. However, they still have a house edge, which gives the casino a slight mathematical advantage over the players. That means you need above-average luck to enjoy a winning session.
Which casino games are Provably Fair?
Original games like Mines, Dice, and Plinko normally use Provably Fair technology. BGaming also makes Provably Fair table games and slots, including blackjack, roulette, Aztec Magic Deluxe, and Lucky Lady’s Clover. However, most slots aren’t Provably Fair, and live dealer games aren’t Provably Fair either.
Do I need technical skills to verify a bet?
No, you don’t need any specialist technical skills to verify a bet when you play Provably Fair crypto gambling games. It’s quick and easy to rotate the seed pair, plug the data into a verification tool, and check the results. That’s one of the reasons why Provably Fair casino games have proved so popular.
