Semi Precision Dice (and precision dice) have no holes for spots (1 - 6), thus greatly reducing weight deviation between each face. To achieve equal probability that all 6 faces appear (as in casino dice used for craps), perfect balance is desired. Shape and weight distribution are the two components of a perfectly balanced die.

Semi Precision Dice are made from durable ABS or Pastello Plastic, a cheaper material than cellulose acetate, the material used for producing precision dice. Cellulose acetate is completely homogenous and free from minuscule air bubbles; the cost of this material is a contributing factor to the high production costs of precision dice.

An Injection Moulding System (similar to that used to manufacture standard dice) is used to produce Semi Precision Dice (precision dice are cut with a precision laser, which again contribute to the high production costs).

A polished, precision mould ensures that the dice are perfect cubes - as perfect as technically possible. The precision mould has a double injection system, whereby the two different colours of the plastic are injected at the same time. Injecting two colours of the same plastic at the same time (one for the colour of the dice and one for the spots), ensures the weight and accuracy, and results in flush faces on all sides which require no painting or filling.

Standard (regular) game dice have either injected or drilled holes for the spots on each face. These holes are then filled with special colouring or paint to make the spots stand out. There is no guarantee that this filling process is exact for each hole, nor is there any guarantee that they are perfect cubes. The quality of Standard Dice varies widely from producer to producer. The preciseness of moulds, and the technique used to cool the liquid plastic are major factors affecting the quality of Standard Dice. Size and deepness of holes, and misshapen faces and edges can greatly affect the fairness of the dice. Standard dice are considerably cheaper than Precision and Semi Precision dice.
