why do (most) dice have the same face placements? As in, why is the 6 usually opposite to the 1, likewise with the 3 and 4? Does this affect the “fairness” of a dice roll, making it a 1/6 chance every roll as opposed to a different value?

why do (most) dice have the same face placements? As in, why is the 6 usually opposite to the 1, likewise with the 3 and 4? Does this affect the “fairness” of a dice roll, making it a 1/6 chance every roll as opposed to a different value?

Answer 1

in ‘regular’ dice (regular referring to traditional, and those used by casinos) the opposite faces always add up to 7. such as 6+1, 3+4, 2+5

i’m not sure about it affecting the fairness but checking this arrangement of the faces is how casinos ensure the dice haven’t been switched to fakes
