Three Strike Universal

Three Strike Universal (TSU) is a minimalist ruleset that can be used as a standalone TTRPG or as an auxiliary system for running long-term narratives in the background of other games (such as relationships, research, etc).

It uses up to 3 six-sided dice and goes well with index cards. 

---

Simple Resolution Each roll gives a Yes/No | And/But result which updates the fiction.

Tracks -- Rolls can be plugged into a track, letting a question be resolved over several rolls. 

The Gameplay Fractal --  A completed track can be used as a result in *other* tracks. This lets you "zoom in" at any point, breaking one point in a track into its own track (and so on).
