Can't really expect the casino to create an algorithm that would prove to be an advantage to players now, can we. I've never really seen crash games being unfair tbh, I mean, even my common sense would indicate that if they didn't crash at lower values, they'd probably be losing out quite a lot.
But then if they would ever made an unfair one, it would simply make a huge impact in their reputation as the possibility of loses are bigger than the wins. I think they are making their own algos that would fit their categories such as how many wins can a user have in their crash games together with the chances they could have from time to time.
But I do disagree with Insanerman, that algorithms do have impact in gambling and knowing it would make a gambler be attentive when to bet and what strategy to use. If we didn't knew algorithm, we'll soon be losing our money as we only know how to make fun and be satisfied.
