SISU TTRPG
A tabletop roleplaying game built on resilience, determination, and the freedom to adventure across any world you can imagine - from epic fantasy adventures to gritty pulp thrillers and modern-day suspense.
What is Sisu?
Sisu is a Finnish word that defies direct translation. It embodies resilience, determination, and an inner strength that carries you through adversity. Pronounced "See-Soo", it is the spirit that powers this game.
Genre Flexible
Fantasy dungeon crawl or corporate sci-fi heist - Sisu TTRPG works seamlessly across all settings. One ruleset, infinite worlds.
Simple Mechanics
Four core stats and a straightforward dice system mean you spend more time playing and less time flipping through rulebooks.
Finnish Spirit
Named after the Finnish concept of determined grit and improvisation - the quality that gets you through any challenge the GM throws your way.
The Four Core Stats
Every character is defined by four attributes, each assigned a die type ranging from d4 to d12. The bigger the die, the more capable you are in that domain.
BODY
Physical prowess - strength, dexterity, balance, stealth, and endurance.
MIND
Mental acuity - research, comprehension, composure, and resisting manipulation.
SENSE
Social intelligence - persuasion, charisma, artistic flair, and reading people.
SISU
Sheer determination - assertiveness, quick thinking, and inspired improvisation.
Fast to Learn, Deep to Play
Create a character in minutes. Distribute your dice. Pick two skills and a flaw. Then gather your party and start adventuring. The GM sets the scene - you decide how your character responds, and the dice make it interesting. That is all it takes to get started with Sisu TTRPG.
