The problem with this aproach, is that everytime I access your site I will have to check the code to see if you didn't change it. Will be way better if you implement a way for us to change it.
Yep. added to the todo.
The seed can't be global, but attached to the session. IMO, the best way to do it is to generate a seed to our session, show it to the user just before any bet, provide a way so we can set our client seed and after the bet generate another server seed to the next bet.
Okay, I'm gonna think on it.
