Dice acts using sex dice. Dice may have numbers that do not form a counting sequence starting at one. One variation on the standard die is known as the "average" die. These are six-sided dice with sides numbered codice_3, which have the same arithmetic mean as a standard die (3.5 for a single die, 7 for a pair of dice), but have a narrower range of possible values (2 through 5 for one, 4 through 10 for a pair). They are used in some table-top wargames, where a narrower range of numbers is required. Other numbered variations include Sicherman dice and
Dice notation on both dice may be interpreted as either 0 or 100, depending on the game rules. The "d1000" (using three 10-sided dice) is occasionally also seen, although it is more common in wargames than role-playing games. A number of notational strategies exist for discarding only certain types of results. Some games extend the standard notation to A"d"X"(k"Y")+"B where, in addition to the above, Y is the number of dice kept (k) from the roll. Whether the dice omitted are the highest, lowest, or the player's choice depends on the game in question. 7th Sea and Legend of the Five Rings
