These are standard-sized black six-sided dice with silver pips for numbering.
They are numbered normally, but are weighted so that they''re more likely to roll six.
They won''t always roll six, but are far more likely to.
In general the longer they roll, the more likely they are to land on six
With a little bit of practice you can pretty frequently get a natural 18 on a roll of the three.
