Dieroller

Dieroller is a simple die rolling program for use with tabletop role playing games. The main interface includes buttons for each of the common polyhedral die types: 1d4, 1d6, 1d8, 1d10, 1d12, 1d20, and 1d100. The main window also includes a number pad for making custom rolls (such as 3d6, 4d12). For games that use the D10 system, there is a second interface that lets you input your die pool and difficulty to determine your number of successes.

What is new in this release:

Version 3.1.2.6 adds the option to re-roll 10s when using the D10 System.
