Can I Play Something Like D&D by Myself?

Yes. You can absolutely play something like D&D by yourself, and you have four real ways to do it: oracle systems that use dice and tables to stand in for a game master, solo journaling games that turn play into writing, published solo adventure modules that branch like the gamebooks you may remember, and AI story games that respond to whatever you type. Each one makes a different trade. Oracles give you the most control and ask the most setup. Journaling gives you the most depth and the least spectacle. Modules give you the most polish and the least freedom. AI story games give you the most immediacy and ask the least of you.

That is the whole answer, compressed. The rest of this essay is what each of those four actually feels like on a quiet Tuesday night — and how to tell which one fits the evening you're having, whether you came to solo play by choice or because your group canceled again.

Playing something like D&D by myself: what am I actually replacing?

Before choosing a method, it helps to name what a game master actually does, because that's the job you're trying to fill. Strip away the voices and the screen and the snacks, and a GM does three things. They keep secrets — you don't know what's behind the door, and that not-knowing is most of the fun. They adjudicate — you say what you attempt, and someone impartial tells you what happens. And they keep momentum — when the story stalls, something kicks it forward.

Every solo method is a different answer to those three jobs. Some hand the secrets to dice. Some hand them to a book. Some hand them to your own honest imagination, and one hands them to something that can answer back. None of them is a lesser version of the table; they're different instruments. A cello isn't a failed orchestra.

Method one: oracle systems — dice as your game master

An oracle is, at its simplest, a structured way of asking yes-or-no questions and letting randomness answer. Is the merchant lying? Roll. Is the bridge guarded? Roll, but the odds shift because you decided a guarded bridge was likely. Around that simple core, whole toolkits have grown: event tables, meaning tables, escalation mechanics that make the world push back the longer you play.

The trade is honest work. You are the player and the referee at once, holding your character's hopes in one hand and the world's indifference in the other. When it clicks, it clicks hard — the dice produce a twist you never would have chosen, and you feel genuinely surprised by a story you are technically writing. When it doesn't click, you're alone at a table with three open rulebooks, doing administration.

Oracles suit people who love systems, who find the machinery itself pleasurable. If you've ever enjoyed building a spreadsheet slightly more than using it, this is your method. It's also the approach closest to the traditional table, which is why it anchors most guides to playing D&D without a Dungeon Master.

Method two: solo journaling games — the story you write down

Journaling games hand you a situation, a set of prompts, and a notebook. You draw a card or roll a die, receive a prompt — a stranger arrives at your lighthouse; the plague reaches your village; you find a letter you were never meant to read — and you write your character's response. Play is the writing. There is no board, no miniature, often no outcome beyond the pages you fill.

What you give up is spectacle. Nothing explodes. What you get is interiority that no other form matches. A combat encounter tells you whether your character survives; a journaling prompt asks how she felt burying the sword afterward, and gives you twenty minutes of quiet to find out. These games produce the strongest emotions per hour of any method here, and they produce an artifact — a notebook you can reread in a year and feel again.

The trade: journaling asks you to bring the energy. On a night when you're full of feeling and want somewhere to put it, nothing is better. On a night when you're drained and want a world to carry you, a blank page can feel like one more thing that needs you.

Method three: solo adventure modules — someone already built the dungeon

Long before anyone said "solo RPG," there were gamebooks — numbered passages, choices at the bottom of each page, a pencil, an eraser, and death on page 214. That tradition never died; it professionalized. Modern solo modules are full adventures written specifically for one player: keyed encounters, branching investigations, campaigns you can play across weeks with a character who grows.

The pleasure here is craft. A good module is authored — an actual designer decided that this clue leads to that revelation, that this fight is beatable but barely. The pacing has been playtested. The twist lands because someone built it to land. You get the secrets a GM would keep, kept properly, because you genuinely don't know what's on the next page.

The trade is freedom. The book only contains what the book contains. Ask a question the author didn't anticipate — can I bribe the guard instead? can I just leave? — and the module has no answer for you. You are exploring a built space, not an open one. For many nights that's exactly right; a well-built space is a gift. But the walls are real, and eventually you touch them.

Method four: AI story games — a world that answers back

The newest answer is the one that most directly replaces the missing person rather than the missing rules. In an AI story game, you type what you say or do — in your own words, not from a menu — and the story responds to that, specifically. Ask the question the author didn't anticipate, and something answers. Bribe the guard. Just leave. The world reshapes around what you actually did.

This method's gift is immediacy. There's no rulebook to learn, no tables to cross-reference, no prep. You sit down and you're in a scene within a minute, and the scene bends to you. For the specific loneliness of a canceled game night — you wanted people and got none — it's the method that fills the most of that absence, because something on the other side is holding the secrets and keeping the momentum, the way a GM would.

The trade is authorship. You surrender the referee's chair entirely; you're a protagonist, not a co-designer. Players who love the machinery of oracles sometimes miss having their hands on the levers. Players who mostly wanted to be inside a story rarely miss them at all.

Which one fits tonight's mood

Match the method to the evening, not to an identity. You don't have to be "an oracle person."

Reach for oracles when you're energized and curious about the machinery itself — when running the world sounds like fun, not homework. Reach for journaling when you're full of feeling and want depth over event; it's the method for nights that want a candle, not a torch. Reach for a module when you want to trust an author — when being surprised by good craft sounds better than improvising. And reach for an AI story game when you want to be carried: when you have an hour, no prep in you, and a strong desire to be somewhere else, inside a story that answers back.

Most solo players end up rotating among two or three of these. They're not rivals; they're moods. For a deeper survey of the whole territory — tools, starting points, and how the methods combine — see our longer guide to how to play D&D alone.

Where Runebook sits in this

Runebook is an AI story game — the fourth method, built to be the sit-down-and-you're-in version of solo play. The Storyteller runs the world: it holds the secrets, adjudicates what you attempt, and keeps the story moving, which is to say it does the three jobs of the missing person at the table. You act by typing whatever you want to say or do, or by accepting a suggested action, or by speaking it aloud. Scenes come with narration read aloud and imagery, so the evening has some spectacle to it after all.

Two things matter for the solo player specifically. The story remembers what matters — the guard you bribed in the first hour is still bribed in the fourth — and it waits. Stop mid-scene on Tuesday, return on Sunday, and the story remembers where you were. You can play fantasy, mystery, horror, romance, historical, sci-fi and more, start from a custom idea of your own, or bring friends into a story when the group finally does show up.

Create an account and start your first story — it's included. The table doesn't have to stay empty. Start your story.
