They are dice.
Most people know of the usual 6 sided cube,
but for those who play D&D or other fantasy games,
there's a whole array of multi sided dice.
This is a standard set;
d4 - purple
d6 - red
d8 - blue
d10 - green
d12 - yellow
d20 - orange
d% - white
So there you have it,
you learn something new every day.
