Boundless
Soulslike, Open-Licensed, and Solo-Friendly
The Boundless System is the open-licensed rules framework for building Soulslike TTRPGs of relentless struggle and resilience.
The world is against you, filled with unimaginable horrors, crushing stress, and ever-looming darkness.
Play until you break. Then stand back up and keep playing. A system that grabs players and never lets go.

The System
Fast, Focused d6s
Roll a handful of d6s. Each 5–6 is a hit. More hits = bigger results. The core is fast to teach and quick to resolve, so the story keeps moving.
Push-Your-Luck Stamina
Spend stamina to grab extra dice when it matters. But you’ll need that stamina to survive incoming threats. Every time you choose to spend stamina, you tighten the tension.
Gear That Matters
Items have four usage dots. Mark a dot to gain an edge on a roll. When they’re spent, they’re worn out, repair them in the fiction or switch tactics.
Momentum, Not Math
Pools are (4d6/6d6/8d6) that build pressure behind the scenes. See them as dynamic clocks. They start with a set number of dice, and as dice drop, danger closes in or progress is made. Until it finally hits and the story pivots hard.
Fights That Bite Back
Enemies use aspects and stamina pools. Every hit from a player’s roll forces a save from the enemy; their turns force saves that riposte.
Built To Share
Open-licensed and creator-friendly. Hack it, reskin it, and publish your own Boundless games, no gatekeeping. Start with the SRD, then make it yours.
Made For Solo And Group Play
