Basic Dice

The Dicenomicon uses fairly standard and common notation for dice, such as is used by D&D, Pathfinder, and many other role playing games (with extensions to support all sorts of other role playing games). In its most simple form, you specify an (option) number of dice to roll, and how many sides those dice have. You can then easily add or subtract either other dice or some constant value. For example:


will roll a six side (cube shaped) die.

3d6 + 2

will roll three of them and add two to the result.

One of the most popular variation on a dice roll is to roll multiple dice and only use the higher/lower dice (and ignore the rest). This is seen in D&D 5e advantage and disadvantage. These can be expressed via




respectively - roll two twenty sided dice and just use the higher one or the lower one.

The Dicenomicon support rolling dice of all common (and most uncommon) number of faces. This include four, six, eight, ten, twelve and twenty sided dice, as well as other sizes and combinations (such as the popular d% to generate a random number between 1 and 100).

One other useful extension that The Dicenomicon provides is being able to specify the color of the dice to be rolled by a single letter code used before the d letter:

Gd8 - Rd8

Will roll two eight sided dice, one red, one green, and subtract the red one from the green one.

The other most popular dice rolling mechanism is the concept of “exploding” or “open ended” rolls. With six sided dice, this is normally done by rolling the dice, and if a “six” shows up, roll another six sided die and add that to the result (and keep doing that as long as a six shows up). This allow the slight chance of even just rolling one die to reach very high results. In The Dicenomicon this would be written as:


(with the '+' indicating an open ended/exploding die)
