I develop the UI if you want me to but I am not a programmer 
Do you know HTML/CSS? That's all I need I may "wrongly" understand, but this article points is about the difficulty to prove the fairness of a shuffling (ie proving the randomness)
So afaiu it doesn't apply to my game because I intend to prove that the player played what I display
div#fdiv{
background: white;
}
Thanks! I didn't notice that on my large screenbackground: white;
}
