The normal die is 6-sided with markings from one to six but many alternatives exist: 2-sided (coins), 4-sided, 8-sided, 10-sided, 12-sided, 20-sided, 24-sided, and ball-shaped with a 100 markings. It is possible to vary these Dice further by exchanging the markings with other numbers, or icons representing resources, actions, or other more specific outcomes. The distribution of the outcomes can be further modified with multiple instances of the same outcome in the predefined set, for example, by creating random numbers from one to three using two markings for each of the numbers in a 6-sided die. Several Dice can be used together to create approximations of normal distributions.
See Dice Games Properly Explained by Knizia for numerous examples of dice games.
Although not mechanically necessary in computers, Dice can be used in computers either because the non-computerized game use Dice or because Dice provide a well-known means of randomizing with well-known distributions. In computer games, the outcome of a die roll may, of course, be fudged to achieve Balancing Effects but the player may over time perceive this and this may prevent the Perceived Chance to Succeed.
Dice support Randomness and Luck in games, and in the case of more complex combinations, the possibility of Strategic Knowledge. They are most common when simulating real world actions and events that are difficult to exactly predict, for example Combat or how successful uses of Skills are. They are the Focus Loci for abstract actions depending on the outcome of the Dice.
