I definitely look for the site to be provably fair. If you can't verify for your self that the algorithms are fair, then how can you know the RTP (or house edge) is accurate. They could say it is one thing, but actually be paying out far less. There are a lot of scam sites out there that are taking advantage of people, and it's really the people's fault because they are willing to play even though it's not provably fair.
Thanks this is what sort of feedback I'm looking for.
I agree that if offering provably fair in any game the casino should be set up in a way where players can verify their bet any time they want.
How often would you actually check the bet seed against your bet, only on losses or every single bet?
Would you trust an auto verifying system where as it would show you that each bet has been checked after play, you would also be able to check it yourself at anytime?
