Any square-based pyramid die would not be fair. i.e. if the sides are
different shapes, then the chances of falling on each side will not be
equal.

What shapes make the best dice?
We need to make sure all the faces are the same shape and that all the
angles and sides are equal, or some faces will be favoured more than
others and so our dice will be "unfair".

There is a patent for a 5-sided dice made up of two opposed triangles
joined by three rectangles which the inventor claims has tested as a
'fair' dice.
