Hello,

I was reading an article about how dice were made and a little bit of history surrounding dice.
Did you know that in early medieval times, dice were often "unbalanced" in the arrangement of numbers, where 1 appears opposite 2, 3 opposite 4, and 5 opposite 6? It didn't matter the material of the dice nor the shape because people used to believe that the outcome was predetermined by the gods.
