Hi!
This is a question that has been on my mind for quite some time. You can see the term 'provably fair' used all over the place in the Bitcoin gambling market but in this case I'm referring to in-house games in casinos which offer the option to prove fairness of the game to the player.
Have you ever proven fairness of a game yourself or know someone who has or do you simply trust a casino claiming their games are provably fair?
For those who already earned reputation casinos of course I don't even verify it but for new casinos there's in need of checking it. Also if I remember there's a third party website that checks or verifies bet of some known casino here's the link
