Scott Gray's Shadowrun Dice Pool Calculator

This program is © 2000 by Scott David Gray.

This program is designed to calculate probabilities when using a Shadowrun open-ended dice pool.

Dice pools are used in role playing games such as Shadowrun. A dice pool is used by rolling a number of dice and, rather than adding them together, comparing the rolls to a target number and counting how many dice meet that target. In Shadowrun, dice are open-ended; if a die rolls a six it is added to another six sided die (which, in turn, is open ended, etc.). If all of the dice roll one, the result is a critical failure.

When entering the fields, be sure that the number of dice you enter is greater than zero, and that the target number you enter is greater than 1.

and here is the form itself:


Number of dice to be thrown:
Target number:

Not cumulative
Cumulative
Both cumulative and not cumulative


This program was designed (and the math calculated) by Scott David Gray, from the Sudbury Valley School.
