Roleplaying games mostly use dice to generate random events. Paper games rely on several kinds of dice -- most often 4-, 6-, 8-, 10-, 12- and 20-sided dice are used. Computers are not limited by arbitrary die forms and thus enjoy the freedom to use any kind of dice imaginable as a random number generator.

Roleplayers use an abbreviated way of describing the number of dice to be rolled to generate a random number. Basically a certain number of dice is rolled, all the face values are added and maybe a modifier is added or subtracted to generate a total. This is normally abbreviated as

and means to roll {x} dice with {y} faces and finally to add the value {z}. {z} can be positive or negative. If {z} is not mentioned, it is assumed to be zero.

EXAMPLES: 1d20 means to roll one 20-sided die to generate a number between 1 and 20. 2d6 means to roll two 6-sided dice to generate a number between 2 and 12. 4d4+3 means to roll four 4-sided dice and finally add 3 to generate a number between 7 and 19. 3d13-9 means to roll three 13-sided dice and subtract 9 to generate a number between -6 and 30.
