Nowadays, we often face questions like «What does Provably Fair mean and how does it work? How can Provably Fair be hacked or How to win it?» We will try to answer all these questions but first, let’s figure out what it is. 

What is Provably Fair Gaming?

Provably Fair Gambling

Thus, Provably Fair in the gambling industry is a process by which any player can personally verify the fairness of the game they play at an online casino. To do this, a special code or Provably Fair Algorithm is generated. With the help of this algorithm, an encrypted key is created with the final results of the game and the initial key, which will allow the player to verify the fairness of the game at the end of the round.

The impossibility of influencing the process is provided by three components:

  1. Server seed – provided by the casino;
  2. Player seed (sometimes several) – generated by your browser;
  3. Nonce – a special variable that increases by one with each round of the game, so that later you can track the dynamics of the session.

Before the start of the round, you receive an encrypted server seed hash. It already contains the result of the round, so the casino cannot change it even if they want to. Also, since you get this hash in encrypted form, you can’t use it to predict a Provably Fair game outcome.

To check the fairness of the game, you need to take two simple steps:

  1. Verify that the hashed server seed value received from the casino is the actual hash of the unhashed server seed value. You can use an online tool like Xorbin to check the seed. Use it to generate a SHA256 hash of the unhashed seed. If these two hashes match, then everything is OK and your game is fair.
  2. Generate each roll result on your own and then compare them to the rolls you made at the casino. To do this, it is also better to use an online tool to speed up the process.

So, let’s compare a regular gaming portal and an online casino using Provably Fair technology and for clarity, it would be more convenient do it in the form of a table:

As we can see, the online casino that uses the Provably Fair system looks more convincing.

Is it possible to cheat and hack this technology?

The number of requests on the Internet related to the possibility of hacking or cheating «Provably Fair» games is quite big. Some sources even offer hacking instructions. However, we do not recommend trusting such sources. You are very likely to either fall into the trap of scammers or infect your device with a virus. 

The «Provably Fair» system doesn’t just use a seed-based random results algorithm, it also provides an opportunity for all interested parties to verify this seed after the round has been played. This means that a hacking attempt will be instantly detected by the casino security service or any player who notices this interference.Thus, we can conclude that the «Provably Fair» technology is very secure, reliable and has not yet been hacked.

Provably Fair calculator 

Let’s estimate the percentage of losses using the Provably Fair calculator, say, for the game «Heads or Tails», based on the Martingale strategy. Recall that this strategy is to double the bet on a loss and return to the original bet on a win. 

So, let’s say we bet $1 always on «Head», with a $100 bankroll. The value of Multiply Loss in our case is 2 (doubling Martingale bets), and the Increase in % is 100.00. For convenience, we will enter the results of calculations in the table:

Roll No.Bet AmountLossWinLosing Streak Odds %
11.0099.00101.0050.50
22.0097.00101.0025.50
34.0093.00101.0012.88
48.0085.00101.006.50
516.0069.00101.003.28
632.0037.00101.001.66

As you can see from the table, the chances of a further losing streak decrease with each loss. On the other hand, the chances of winning increase.

You should keep in mind that when using the Martingale System, your bets increase exponentially. So, when you’re not sure if the next roll will win, always play with a bankroll that you can afford to lose. In this case, the eighth roll will knock you out of your $100 bankroll.
