Perhaps to mitigate concerns that the pips on the faces of certain styles of dice cause a small bias, casinos use precision dice with flush markings. Common dice are small cubes most commonly across, whose faces are numbered from one to six, usually by patterns of round dots called pips. (While the use of Arabic numerals is occasionally seen, such dice are less common.) Opposite sides of a modern die traditionally add up to seven, implying that the 1, 2 and 3 faces share a vertex.

Some dice, such as those with 10 sides, are usually numbered sequentially beginning with 0, in which case the opposite faces will add to one less than the number of faces. ""Uniform fair dice"" are dice where all faces have equal probability of outcome due to the symmetry of the die as it is face-transitive. Theoretically, this includes: Long dice can in principle be made with any number of faces, including odd numbers. They are based on the infinite set of prisms. All the rectangular faces are mutually face-transitive, so they are equally"

If one holds such a die between one's fingers at two of the vertices such that the even numbers are on top, and reads the numbers from left to right in a zigzag pattern, the sequence obtained is 0, 7, 4, 1, 6, 9, 2, 5, 8, 3, and back to 0. The even and odd digits are divided among the two opposing ""caps"" of the die, and each pair of opposite faces adds to nine. When casting a"

Stress dice are open-ended and are re-rolled each time the roll equals the die's maximum value. A natural 1 on the first stress die roll indicates a possible botch, requiring a botch roll to confirm the botch. Botch dice are d6s; only a roll of 1 indicates a botch. Each prime"

The dice in the first and second Miwin sets have similar attributes: each die bears each of its numbers exactly once, the sum of the numbers is 30, and each number from 1 to 9 is spread twice over the three dice.
