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?
Actually the in-house games are usually provably fair indeed like dice, keno and boost. You can easily verify the bets and I can give you an easy link to verify all your bets in a single place (thanks BTCGOSU for this work!) -
https://www.btcgosu.com/tools/provably-fair-verifier/Games that are provided by third party providers, mostly slots are not provably fair and hence are not as popular as the provably fair games. I have played a lot of slot games and I can vouch that for some providers like Relax Gaming and Pragmatic Play but then again they are not provably fair so play at your own risk. I would request any casino owners reading here to implement the buy-feature for slots in your provably fair games if possible, that is a crucial part of gambling for slot players.
