To go with the rigged dice, I created a die that is not rigged. This die rolls fair and as expected. It can be mixed in with the rigged dice for more believable rolls or to act as a control dice. Since the dice are the same size and design, the only differentiation is by print orientation and the minute shift in center of mass. This die is great as the “normal” die for board games or DnD, and makes the rigged dice much more believable when substituted. Works great with the rigged dice as a lesson on statistics and probability.
