If you’ve been wondering what the meaning of provably fair is when it comes to online casinos, then you’re in the right place. This essentially an algorithm that ensures the outcomes of casino games are completely random.

But how does it work? Well, without going into too much detail, the algorithm uses a blockchain which then enables the randomization. This is no different to flipping a coin or shuffling a deck of cards. The key difference is that the algorithm is happening online and even though you can’t see it, you can verify that it’s working.

What is the meaning of provably fair?

This is a super common query that comes up a lot, particularly among those new to online casinos. So, we thought it was about time that we write a guide giving a detailed overview of what exactly this means. Provably fair is an algorithm that’s been built to ensure that the outcome of various online casino games are random. If you want to get technical, then the algorithm uses something called a blockchain to ensure that the randomization is taking place.

This is similar to flipping a coin with a 50/50 chance of landing on either side, or if you shuffled a deck of cards and then pulled one out randomly. The only difference really between these actions and the provably fair algorithm is that it’s happening online. But the real shining star of the provably fair algorithm is that you, the player, can verify that casinos have it in place to ensure fairness. Pretty cool right?

Let’s take an example, say you’re placing a few rounds of blackjack. The provably fair algorithm will produce all of the hands and it then stores that data. Then, if you would like to, you can request access to this data to verify whether the hands were indeed completely randomized using the algorithm. And because it’s what’s known as a ‘public ledger’ you don’t need to use a third party company or get any kind of permission from the regulatory body to access this information.

The provably fair algorithm is one of a number of safety features online casinos use, similar to those we outlined in our ‘How do you know if you have a gambling problem’ guide.
