Re: Breaking: Shuffle-based Provably Fair Implementations Can Cheat Players (proof)
I actually did hit the modulo bias quite often, since I'm searching the entire space. I think it's silly that bitZino even had a modulo bias. It's a casino. 
Quick and easy fix:
Quick and easy fix:I was just referring to my version, moduloing a random 2^256 number by is going to be for all intents and purposes perfectly distributed.
Also, I think you're grossly overestimate the risk in releasing your code -- it's not a huge task to write, and I really doubt it's worth the effort to even implement (assuming you were a psychotic casino owner), unless you were running a 0 edge game. (If you assume that user play is loss-constrained, it's **better** for a casino to have a lower edge). That's not an excuse, and casinos should definitely fix it. But it's not like casinos are going to be scrambling to rip off players
