While we all know that there are such things as loaded dice, we tend to assume that normal dice are just that - normal - and that each face has a 1 in 6 chance of landing face up.

However we were just wondering... the spots on a dice are often made with small indentations on the face, which are filled with a contrasting colour to the dice. But that indentation represents a space rather than the solid plastic the dice is made from. The 1 is always opposite the 6, and you might think that as less material is missing on the 1 side than on the side with the 6, that this might shift the centre of gravity a bit? Maybe the face with the 1 is slightly heavier? Maybe there is a slightly higher chance of getting a 6 than a 1?

We found these dice in a shop, and the label said that the spots were size compensated to try and make the dice totally fair.

More research is probably needed....
