Casinos don't take any chances when it comes to profit so they don't use just any dice when thousands of dollars are riding on a roll.
Casino dice are called perfect or precision dice because of the way they are made.
They are as close to being perfect true cubes as possible, measured to within a fraction of a millimetre, manufactured so each die has an absolutely equal chance of landing on any one of its six faces.
Casino dice are specially hand made to within a tolerance of 0.0005 of an inch.
The spots are drilled and filled with material that is equal in weight to the material removed.
