The Sapio System

The Sapio System is a roleplaying game ruleset that utilizes Spiral Dice. It is a lightweight, setting-agnostic, flexible framework for telling stories. The “Spiral” name reflects the mechanics embedded in the dice, which inject complications or drama into scenes as the characters move through the shared imaginative space.

Sapio leverages the dice to create a dynamic story from a few simple elements. Character descriptors are quick to craft and are the primary influence on how likely a character is to succeed at a given task. Actions taken by the characters are not confined to skill lists, so characters are free to “try anything” in response to challenges they may encounter. Finally, Action Sequences provide a cinematic framework for tense group moments like combat or chases, with constantly evolving action aided by the complications from rolling Spiral Dice.

The rules are 52 pages, with illustrations and examples. Included in the downloads are a character sheet and the digital "dice bag" that can be imported into the Roll My Dice app. If you would like to use the dice in a browser, you can roll them using the Togetherness Table or with Masukomi's Spiral Dice Roller.

You can buy physical Spiral Dice to roll at our online store.
