What are Provably Fair Casinos

Provably fair casinos are those that run on the provably fair algorithm. This is a technology that allows online games to reach new heights of randomness, openness and fairness. The algorithm uses all the advantages of blockchain to ensure the randomness of online casino outcomes such as flipping a coin, spinning reels and shuffling cards.


The main difference between this and the standard RNGs used in traditional online casinos is the fact that players can verify the actions themselves, leaving absolutely no room for doubt. This means that there is no need to use third-party testing agencies to verify fairness.


What is provably fair? There is more than one way for the provably fair method to be implemented in Bitcoin casinos. The most common one you will find has an algorithm that calculates the result every time a new game is played using three different variables:

  • The serverseed, which is provided by the casino
  • The clientseed, which is provided by whatever browser you are playing on
  • The nonce that changes with each hand. It increases every time by one, allowing you to keep track of which game round is which when the session ends.

Before you start any game, there will be a hash with info about algorithm serverseed, which will be fully encrypted. This will contain the outcome of the game that you are about to play. It cannot be changed by the casino and, because it is encrypted, you won’t be able to try and work out the result of the game before you play.


In comparison, how the RNG works on standard casino games means you have to rely on the casino entirely. There is no way you can check whether or not it has been tampered with, you can only rely on the testing being accurate.

. . .

How to Find the Best Provably Fair Casino

Although provably fair algorithms ensure complete randomness and trust, that is no guarantee that the casino itself is good and legit. Here are the ways in which we find the best crypto casinos that use the provably fair system.

Provably Fair Crypto Games

All sorts of games can be played on the blockchain using a provably fair algorithm – from coin flip to slots, dice games to poker. Here are some of the provably fair games that we would expect to see on the best crypto casinos:


There are numerous dice games to enjoy  – it could be players trying to guess the outcome of the roll of dice or which player gets the highest total. This is one of the favorite blockchain-based games.

Dice Casinos

Slot Games

Just as with traditional casinos, slot games are popular in provably fair casinos. They come in all shapes and sizes with all different themes. When playing blockchain slots, each spin you play is generated through a hash received at the start which you can check at the end of the spin.

Slot Casinos


Crash is a popular blockchain game. You need to trade bitcoin or other cryptos and avoid the market crash in the game. This is a super simple game and you don’t need any experience in gambling.


This game is the same whether you play it on a blockchain crypto casino or a traditional fiat currency casino. You simply need to get closer to 21 than the dealer without going over (bust). The only difference is the game’s provably fair algorithm.


Again, this works in the same way as traditional roulette, you can bet on red or black, odd or even, or your favorite number. The result of the spin will be determined on the provably fair algorithm.


One of the most popular casino games in the world… and the best provably fair casinos will offer all different types such as Texas Hold’em and Stud Poker. Whoever gets the best hand wins.


Banker Hand, Player Hand or tie. You simply predict which hand you think will be closest to 9 and you win. This game will be available to play on the best provably fair casinos.



This isn’t a standard casino game, and is based on the spin of the wheel of fortune. If you land on the colour you bet on then you win.

Coin Flip

This is a standard provably fair casino game and is as simple as it can be. You bet on the flip of a coin, heads or tails, and the provably fair algorithm decides whether you win or lose.

Treasure Hunter

You have to find the clues and work out the riddles to find the hidden treasure.

Rock, Paper, Scissors

We all know of the childhood game of rock, paper and scissors. This is given the online crypto casino upgrade and whether you win or lose is worked out by the provably fair algorithm.


Another crypto game is Plinko. You drop a circular disk from the top of a table and it plinks down a zig-zag wall with money prizes at the bottom.

Plinko Casinos


Is a provably fair game that is simple – you just predict whether the next card in the pack will be higher or lower than the previous one.

Hi-Lo Casinos


This is one of the most popular provably fair casino games, based on the computer game. You need to uncover small squares on a board whilst avoiding the mines.

Other games to look out for include bingo games, lotteries, lino, keno and more. The more crypto provably fair games they have on offer, the better.

Can Players Hack the Provably Fair Games?

No. Before the game has even started, there will already be a hash code that has been generated. This hash code will contain all of the information about the game you are just about to play and the result. This means that it is already decided before the game even starts, what hands are going to be the winning or losing hands.


This information is stored securely in a hash that cannot be broken or hacked. It can only be read at the end of the game when you receive another piece of code.


There are several reasons as to why it would be impossible for you, or any other player, to hack or cheat at a provably fair casino. The most obvious reason is because there hasn’t yet been invented a computer or program that would be able to crack the hash code fast enough for a player to read it and use it to place their bets on the winning outcome before the game starts.

For now, computers are simply not that far advanced.


As well as this, all provably fair casinos are blockchain-based. If one node detects any suspicious activity then it will notify the entire network and the person suspected of such actions will be kicked out of the public ledger straight away.


Ultimately, blockchain-based provably fair casinos have security measures in place that would make banks green with envy. Not even the best hacker in the world can bypass their security. Even try it and you will be in some serious trouble.

Differences Between Provably Fair Casinos and Traditional RNG Casinos

There are several differences between traditional RNG casinos and provably fair casinos.

  • If you play on a provably fair casino, then there will be no need to look for third-party verification and authentication. You will be able to check the results yourself and there is no need for regular testing and audits.
  • The provably fair algorithm provides players with the highest level of trust because it cannot be tampered with in any way. This cannot be proven if you are playing at an untested casino that uses RNG technology.
  • Provably fair allows players to analyse wagers and their actions, and then compare them to the outcomes, meaning complete transparency.
  • Generally, a provably fair casino will have a higher Return to Player (RTP) than an RNG casino, which is one of its biggest selling points.

There are some areas, however, where RNG casinos have the edge – although not many.


An RNG is a Random Number Generator, which is a system which randomly generates a selection of numbers and letters etc that could never be predicted simply by random chance. It is a mathematical system which displays numbers chosen at random, and it is used in traditional casino games including slots, poker, blackjack, baccarat, roulette and other video casino games.


The whole concept of Random Number Generators has existed for years, but more recently it has been applied to online gambling. All licensed and regulated online casinos will be required to have all games operated by RNGs, which will need to be tested and verified at regular intervals.


Although RNGs are most commonly used at traditional fiat casino sites they are also used at certain crypto casinos as well.

The benefits of RNGs are:

  • They can be used at both fiat casinos and cryptocurrency casinos. RNGs are compatible with all different games and not just casino and gambling games Generally, when tested and verified, they are completely fair and trustworthy.
  • RNGs are considered, by most, to be secure and trustworthy and most are tested on regular occasions by legitimate third-party agencies.
  • This system offers a very high level of randomness of outcomes perfect for the online gambling industry.
  • However, they can be hacked and you need to be sure you are playing at a site that is tested regularly.

In terms of which one is best, well, there isn’t a clear-cut answer and it depends on which you feel most comfortable with and what type of casino you prefer to play at. If you want to play at a cryptocurrency casino and prefer to be able to check results yourself, provably fair is great.


However, if you wish to play on a casino that uses fiat currencies and crypto, RNG games will be more easily accessible as provably fair only works on the blockchain.
