SIN System

About the SIN System

To use the  SIN System, you’ll need paper, this booklet, and a stack of 2-sided tokens. Coins will do, but a particular type of token with black on one side and white on the other works best. You’ll also need a Storyteller and one or more players.

The SIN System, at its core, is a narrative game. It is also just that, a game. The most important thing is to always make sure you’re having fun. Please make sure to use proper RPG safety tools to ensure the maximum comfort and enjoyment of everyone involved. For more information check out the TTRPG Safety Toolkit.

This SIN System (Simple Interaction Notation System) is a powerfully simplistic system for running a variety of different RPGs, such as otHELLo: EXAULT/SIN.

The Core Rules contain the system at its most basic, though it is easy to expand upon to run games as a Game Master sees fit.
