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 pool superhuman ability or other conditions; a common one is to allow high (or low) rolling dice to be rolled again, the second roll counting as if it were an additional die. Dice pools are more complex to explain and less intuitive than traditional "roll over" or "roll under" systems. On the other hand, they are faster to resolve if there are a lot of modifiers as it's easier to count each individual die that succeeded than it is to add four or five separate modifiers to a die roll. Therefore, whether dice pools are faster depends on how much detail
