Use Troll online

There is a web interface for Troll. This is the easiest way to use Troll, and is sufficient for most users.

You can roll dice and calculate probabilities. There are some limitations on probability calculations to avoid stressing the server, so calculations that use a lot of time. This will affect some (but not all) calculations involving many dice or rerolls. If you get into this limitation, you can run Troll on your own computer (by downloading and compiling the sources below), but that will be with a more primitive user interface.

About Troll

I have combined my research into domain-specific languages and my interest in board games and role-playing games to design and implement a language for specifying dice-roll mechanisms.

Based on experiences with Roll, I in 2006 redesigned the language to make it easier to use and added a few new features. The result is Troll, which is the current version, alebit extended with many new features since its release.
