Chance & Effect

Chance & Effect is a leaflet style rules-light TTRPG system that encourages players to balance risk and reward. All you need to play is a standard dice set with a d20, d10, d8, d6 and d4.

Players get to decide how they balance their chances of succeeding and the rewards for doing so.

Simple, fast and without setting, Chance & Effect can be used to run single impromptu, improvised sessions or longer campaigns.

Chance & Effect is available in colour or a printer friendly black & white version.

Chance & Effect was revisited, revamped and remastered for Dice Jam Summer 2021.
