Rigged Backgammon Dice Demo
Player 1 always starts and receives normal random dice.
Player 2 always receives doubles.
Player 1's Turn
Player 1 will receive a normal random roll.
Rules
Player 1
always goes first and rolls two independently generated dice.
Player 2
always receives a double.
The value of the double is still randomly selected,
so 1-1, 2-2, ..., 6-6 each have probability 1/6.
Random die algorithm:
byte = secure random integer from 0 to 255
if byte >= 252:
generate another byte
die = (byte % 6) + 1
