Sometimes dice rolls in a game does not seem right. The first thought that comes to mind is either that dice is somehow biased or its randomness is broken. I wanted to prove that this is not the case. It's just statistics, usually you get games with expected dice rolls, but sometimes you don't.

In normal games with 60 rolls the dice usually varies. But as the game and roll count increases the correct bell curve starts to appear.
