Solo TTRPG Guide: Play Tabletop RPGs By Yourself

Ironsworn has been downloaded over 300,000 times. Thousand Year Old Vampire sold out its first print run. r/Solo_Roleplaying has more members than some mid-size actual-play podcast fanbases. Solo TTRPG isn't a niche anymore - it's a full-blown corner of the hobby, and it extends way beyond D&D.

If you've been playing solo tabletop RPGs with nothing but oracle tables and a journal, you already know. If you're just discovering that solo roleplaying is a thing people do on purpose (and love), you're in the right place.

What Solo TTRPG Actually Means

Solo TTRPG is playing a tabletop roleplaying game by yourself - no GM, no party, just you and whatever system you're using to generate surprises. The "surprise" part is key. You need something to replace the GM's brain: oracle tables, random generators, journaling prompts, or AI. Without that element of the unknown, you're just writing fiction with extra steps.

The Major Solo TTRPG Systems

Not all solo RPGs work the same way. Some are built from the ground up for one player. Others are traditional RPGs with solo frameworks bolted on. Here's what's worth your time.

Ironsworn / Starforged

The gold standard. Shawn Tomkin's Ironsworn (dark fantasy) and its sci-fi successor Starforged were designed for solo play from day one. The "oracle" system is baked into the core mechanics - you make moves, consult tables, and let the fiction snowball. The momentum/progress track system creates genuine tension without a GM. When you roll a miss on a critical move and watch your carefully built momentum drain away, it hurts - and that emotional investment is what separates solo roleplaying from creative writing.

Ironsworn also has a cooperative mode, so if you eventually rope a friend in, you don't need a new system. The community has produced hundreds of custom oracles, asset cards, and supplements. Sundered Isles (the pirate expansion for Starforged) is particularly good.

Ironsworn is free. Starforged is worth paying for. If you've never played a solo TTRPG before, start here. Seriously.

Mythic Game Master Emulator

Mythic isn't a game - it's a GM replacement you bolt onto any RPG you already own. Want to play Call of Cthulhu solo? Mothership? D&D 5e? Mythic handles the "what happens next" part with its Fate Chart and scene-based structure. The second edition cleaned up the chaos factor system and added more nuanced oracle tools.

It's the Swiss army knife of solo roleplaying. Not the prettiest tool, but it works with everything.

Thousand Year Old Vampire

Tim Hutchings made a journaling game about being an immortal monster watching everyone you love die. You answer prompts, create memories, and are forced to forget old ones as new experiences pile up. It's less "game" and more "structured creative writing that makes you feel things."

Fair warning: this one can get genuinely dark. That's the point.

The Wretched

A solo journaling game played with a Jenga tower and a deck of cards. You're the last survivor on a wrecked spaceship, recording audio logs as the creature outside gets closer. When the tower falls, you die. The physical component adds real tension that pure dice-rolling can't match.

The Wretched spawned an entire "Wretched & Alone" SRD that other designers have built on. If you like the format, there are dozens of variants.

Ker Nethalas

A dungeon-crawling solo RPG with a beautifully grim aesthetic. You explore procedurally generated dungeons, manage resources, and try not to die (you will die). The book itself is gorgeous - it feels like an artifact from the world it describes. It scratches the old-school dungeon-crawl itch without needing a group or a GM, and the resource management keeps every decision tense. Do you use your last torch to explore one more room, or head back to camp? If you need to stock a treasure hoard on the fly, our loot generator can roll one up in seconds.

Scarlet Hero

Kevin Crawford designed Scarlet Hero specifically to let one player tackle adventures written for full parties. It rescales combat math so a single hero can fight encounters meant for four. If you have a shelf full of OSR modules gathering dust, Scarlet Hero lets you actually play them.

Four Against Darkness

A dungeon-crawling game that plays more like a board game with RPG flavor. Roll dice, draw rooms on graph paper, fight monsters. If you want to check whether a fight is survivable before you commit, an encounter calculator can help you gauge the odds. It's lighter than most entries on this list, which makes it a solid entry point if you want something you can pick up and play in 20 minutes.

Oracle and Emulator Tools

If you're playing a traditional RPG solo, you need something to answer the questions a GM normally would. That's where oracles come in.

Mythic GM Emulator (mentioned above) is the most popular, but it's not the only option:

• MUNE (Minimal Universal Navigator Engine) - A stripped-down, free alternative to Mythic. Fits on one page. Good for people who find Mythic's chaos factor system fiddly.
• Game Master's Apprentice cards - A deck of cards packed with random prompts, sensory details, difficulty numbers, and yes/no answers. Shuffle, draw, interpret. versatile, and the physical cards feel better than rolling on a table.
• Motif Engine - Part of the Motif SRD framework. Lightweight, flexible, and free.

The common thread: oracles work by giving you just enough information to trigger your imagination, then getting out of the way. The best oracle is the one that generates results you wouldn't have thought of yourself.

AI Tools for Solo TTRPG

Oracle tables are elegant. But they can't describe the terrified look on the innkeeper's face when you mention the Hollow King, or improvise dialogue for a character you just invented. AI tools fill that gap, and they've gotten dramatically better at it.

ChatGPT and Other LLMs

You can absolutely run solo TTRPG sessions with ChatGPT, Claude, or any general-purpose LLM. Give it a system prompt describing the game world and rules, and go. The upside: infinite flexibility. You're not locked into any system, setting, or tone. Want to run a solo Mothership session set on a derelict colony ship? A Blades in the Dark score with no crew? Just describe what you want and start playing.

The downside: you're doing all the prompt engineering yourself, it forgets context mid-session, and it has a habit of being way too agreeable. You say "I attack the dragon" and it says "great idea, you succeed!" That's not a GM - that's a yes-man. You can mitigate this with detailed system prompts that instruct the AI to be adversarial and enforce rules, but it takes work to get right, and even then, context window limits mean long campaigns lose coherence.

AI Dungeon

The OG AI-powered RPG experience. AI Dungeon pioneered the format back in 2019 and still has a huge community. It's more freeform interactive fiction than structured TTRPG, but it can scratch a similar itch. The newer models are significantly better than the GPT-2 days, and the world-building tools let you create persistent settings. The trade-off is that it doesn't enforce any particular rule system - it's collaborative storytelling with an AI, not a rules-driven RPG simulation.

StoryRoll

Full disclosure - this is us. StoryRoll is purpose-built for solo tabletop RPG sessions, specifically D&D 5e right now. Unlike general-purpose AI, it actually tracks game state - your character sheet, inventory, HP, spell slots. It knows the rules and enforces them, which means it can say "no, you can't do that" when appropriate. That's the part most AI tools get wrong.

If you're specifically looking to play D&D alone, it's the most structured AI option available - and you don't need a VTT to use it. We've also written a comparison of AI dungeon master tools if you want to see how the options stack up.

How to Get Started with Solo TTRPG

You don't need to buy anything. You don't need to read 400 pages of rules. Here's the low-friction path:

Pick one system and commit. Ironsworn is free and designed for solo play. That's the recommendation. If you want something lighter, try Four Against Darkness. If you want AI-driven, try StoryRoll.

Start a journal. Physical notebook, Google Doc, Obsidian vault - doesn't matter. Write down what happens in your sessions. Solo roleplaying becomes exponentially better when you record the fiction. Your past sessions become a resource your future sessions draw from. Characters recur, consequences compound, and suddenly you have a campaign.

Play short. Your first session should be 30-45 minutes. Don't try to run a six-hour epic. Solo TTRPG is best in focused bursts - a single scene, a dungeon room, one dramatic conversation. You can always come back tomorrow.

Accept the weird. Oracle tables will give you results that don't immediately make sense. That's a feature. The creative act of interpreting "betrayal + nature + hastily" into a coherent story beat is where the magic happens. Don't reroll when the result feels strange - lean into it.

Don't optimize the fun out of it. It's tempting to research every solo system, compare oracle mechanics, and build the perfect setup before playing a single session. Resist that urge. The solo TTRPG community is full of people who spend more time prepping systems than actually playing. The best system is the one you'll use tonight.

Mix and match. Most experienced solo players combine tools. Ironsworn for the core mechanics, Mythic's meaning tables for NPC motivations, a dice roller when you need quick results, and maybe an AI tool when you want rich dialogue. There's no purity test. Use whatever makes the fiction better.

Why Solo TTRPG Hits Different

There's a specific kind of creative satisfaction in solo roleplaying that group play doesn't replicate. In a group, you're collaborating - which is great, but you're also compromising. You share screen time. You accommodate other people's schedules, playstyles, and character arcs.

Solo TTRPG is just you and the story. You play at 2 AM on a Tuesday if you want. You follow the weird side quest. You let your character make the catastrophically bad decision because it's what they'd do, without worrying about derailing someone else's fun. The pacing is entirely yours.

It's also a good creative writing exercise. The constraints of game mechanics and oracle results push you into narrative territory you'd never explore on your own. Some of the best fiction moments in solo RPG come from desperately trying to make sense of a random oracle result that seems impossible - and then discovering it's the most interesting thing that could have happened.

Community Resources

Solo roleplaying has a active community. Here's where to find your people:

• r/Solo_Roleplaying - The hub. Session reports, system recommendations, oracle comparisons, and general enthusiasm. Genuinely one of the most positive RPG communities on Reddit.
• Me, Myself & Die (YouTube) - Trevor Devall's actual-play solo RPG series is the gold standard for showing what solo TTRPG looks like in practice. Season 1 uses Savage Worlds + Mythic. Season 2 uses Ironsworn. Both are excellent.
