D&D is built around a group at a table, but a lot of people want to play it alone - to try the game without scheduling a group, to explore a character's story on their own terms, or just because a full table isn't available that week. That's a legitimate way to play, and it works.
How solo D&D actually works
Solo D&D replaces the human GM with one of a few approaches:
- Oracle-based play, where you ask yes/no questions and consult random tables or dice to get an answer, then interpret it into the story yourself.
- Guided or structured solo modules, written specifically to be played by one person, with built-in branching.
- GM-assisted solo tools, where something else handles the improvisation and pacing a human GM would normally provide, while you still make every decision for your character.
All three are "really playing D&D" - you're still making choices, rolling dice, and following the rules for your character. What changes is who's generating the world's reactions.
What you actually need
You don't need a group's worth of prep to try solo play. At minimum:
- A character (even a simple one)
- A starting situation - a location and an immediate problem or goal
- A way to resolve uncertainty when you don't know what happens next (oracle tables, a solo module, or a guided tool)
You don't need a full campaign outline before your first solo session any more than you would for a group session.
When solo play is a good fit
Solo D&D tends to work well for:
- Testing a character concept before bringing it to a group table
- Playing during weeks your regular group can't meet
- Learning the rules at your own pace, without the pressure of a full table watching
- Exploring backstory or downtime scenes for a character from an ongoing group campaign
It's a different experience than group play - you lose the improvisation and surprise of other players' decisions, but you gain complete control over pacing and tone.
It's not a replacement for a GM's creativity
Solo play tools can generate scenes, complications, and NPC reactions, but the interesting decisions - what your character actually does, who they trust, what they risk - are still yours. Treat solo tools as a way to keep the story moving when you're playing alone, not as something making the story for you.
ArcForge's Solo Play mode is built for exactly this: guided scenes and choices so you can run a character through a story by yourself, using the same character sheet and tools you'd use at a full table.
