Solo tabletop roleplaying was a fringe within a fringe until roughly 2020; five years later it is one of the fastest-growing corners of the hobby, driven by pandemic-era isolation, journaling-game breakthroughs like Ironsworn, and the realization that a lot of what makes TTRPGs great does not actually require other humans. This is a working map for somebody arriving from group play who wants to know what solo can and cannot do, and for a curious lurker who wants a way in. I have deliberately not included AI-driven prose generators posing as TTRPGs; they are their own category and conflate two different value propositions.
Games written from the ground up as solo experiences. Not adaptations of group games; games where playing alone was the design brief.
One-page or short games structured around writing rather than playing. Often draw a card, roll a die, write a paragraph. The gateway into solo for a lot of players.
Oracles, GM emulators, and random tables that let you run D&D or Call of Cthulhu or Blades in the Dark solo. If you have a game you already love, this is the path.
The SRD Chris Bissette open-sourced in 2020 spawned a whole genre of Jenga-tower solo games. Bleak, personal, thoroughly readable in an evening.
LLMs as oracles, prompt libraries, and the debate about what AI-augmented solo TTRPG can and cannot be. Skeptical about the marketing; useful about the tools.
Where the solo TTRPG scene actually lives. Reddit and YouTube run the discourse; podcasts run the deeper interviews.
