The Short Answer, Yes.

    But if the Random Number Generator (RNG) is open source, it’s highly unlikely that any casino would risk using shady code because it could be proven by anyone, at any time.

How Can A Game Pass Fairness Verification If It’s Not Fair?
     The provably fair algorithm is only one part of the process that is used to generate the game results that you see on your screen. Different games use different RNG. Some are very simple with only a few steps while others are required to convert the provably fair hash string to perform very long and complicated math functions. The more complicated the game’s rules are, the more complicated the process is to get that game’s results.  

    The verification process used by most sites goes only as far as proving that the casino did not change the server seed after you placed your bet. This is always the very first step in a process that can have an infinite amount of steps afterwards. Check out this detailed walkthrough of the most common type of provably fair verification.

    In a previous article I gave a very simple explanation of what provably fair is and why it’s important. Basically, the provably fair algorithms present you, the player, with the opportunity to “cut the deck” so you can be sure any future games using that seed pair will be random. When dealing with physical cards, cutting the deck is not the step that produces the game result. There are still many rules to be considered and steps to take on the way to the final result. Depending on which game is being played, this can be how many cards are dealt, which order they are dealt in, how many rounds per game, etc. Online casinos are no different. Except that all these rules and processes are carried out using mathematics and code.

    I hope this has shed some light on the fact that the provably fair algorithm is not what creates your game’s result. It’s all the math that happens afterwards. If a casino is loudly advertising provable fairness but they are are keeping their code in darkness, they can not be trusted to provide players with a provably fair experience. I would like to emphasize on the fact that just because a bet passes provably fair verification, does not mean that its hash was used in a fair RNG.

So Where Is It Safe To Play?
    Hopefully, the answer to this question is not something you are expecting to take away from this post. The whole point of provably fair RNG is to remove the trust from the gambling experience. If I were to list a bunch of sites that are provably fair, it would be meaningless. Any casino can change the way they operate in an instant. So rather than acting as the police of crypto casinos and telling you what is safe and what is not with an endorsement, I’ve opted to provide you with the knowledge required to make your own decisions on where to play. I can say for certain that BC.Game is the best provably fair casino in the world. Yeah, it’s biased. But it’s also true.
