How to Play a Solo Fantasy RPG Without a Game Master: 3 Methods Compared

How to Play a Solo Fantasy RPG Without a Game Master

Most tabletop roleplaying games assume a table: three to five players and one person behind the screen running the world. Take away the group and you can still play. Take away the Game Master and you have a harder problem, because the GM is doing four jobs at once. This guide covers what those jobs are, the three ways solo players cover them, and an honest look at what each one is good and bad at, so you can pick the one that suits how you like to play.

What a Game Master actually does

"Play without a GM" sounds like it means losing one person. In practice you lose four roles:

• Narrator. Describes the place you're standing in, what you can see and hear, and what changes when you act.
• Every other character. The innkeeper, the guard who doesn't believe you, the villain who monologues at the wrong moment.
• Referee. Decides when a roll is needed, how hard it is, and what success or failure means.
• Keeper of secrets. Knows what's behind the door before you open it. This is the job solo play struggles with most, because you can't surprise yourself on purpose.

Each solo method below is really a different answer to the question "who does those four jobs now?"

Method 1: Oracles and random tables

This is the classic pen-and-paper approach. You play your character, and when you'd normally ask the GM a question ("Is the bridge guarded?"), you ask an oracle instead: a yes/no table you roll on, often with options like "yes, and…" or "no, but…". Random tables for encounters, treasure, weather and NPC moods fill in the rest.

Who does the four jobs: you narrate, you voice every NPC, you referee, and the dice keep the secrets.

Good at: genuine surprise, since nobody knows the roll in advance, including you. It costs nothing beyond dice and paper, and you can take it anywhere.

Less good at: momentum. Every few minutes you stop playing to look something up, roll, and work out what the result means in this scene. Some players love that puzzle. Others find it turns the evening into admin.

Tip: phrase oracle questions so either answer moves the story forward. "Is someone following me?" is better than "Is the road empty?", because a "no" to the second question gives you nothing to work with.

Method 2: Journaling games

Journaling RPGs swap the combat-and-dungeon loop for writing. Prompts (usually drawn by cards or dice) ask questions about your character's life, and you answer in prose. There's often no "winning", just a story that builds up across entries.

Who does the four jobs: the prompts replace most of the referee role, and you write everything else.

Good at: character depth, reflection, quiet evenings, and players who already enjoy writing.

Less good at: the feeling of a fight going wrong, a trap springing, or an NPC pushing back. If what you miss from a table is the back-and-forth, journaling probably won't scratch that itch.

Method 3: An AI Game Master

The newest option hands the narrator, NPC and referee jobs to an AI. You describe what your character does, and the AI tells you what happens. This is the approach VoxDungeon takes, so here is specifically how it splits the work:

• Narration and NPCs: an AI language model writes the scene and voices characters in response to what you say. Narration is read aloud by text-to-speech, and NPCs keep a consistent voice across the session.
• Refereeing: when a roll matters, the dice are rolled by the game server, not invented by the AI, and the result shapes what the narrator describes next.
• Your character: a real sheet with hit points, armour class, inventory and equipment, built from 9 races and 12 classes. Rules content is based on the 5e SRD (SRD 5.1).
• Your input: speak your turn into the mic (it uses your browser's built-in speech recognition) or type it. Each turn also offers a few tap-to-choose suggestions under "What do you do?" for when you're stuck.

Good at: momentum. There's no lookup step and no stopping to work out what a roll means, so a session moves like a table conversation. It also handles the "every other character" job, which is the most tiring one to do yourself.

Less good at: an AI narrator improvises, so it doesn't hold a hidden map the way a prepared human GM does, and it can occasionally lose track of a minor detail from much earlier. The rest of this guide includes habits that help with that.

Side-by-side

A sample exchange

Here's what a few turns look like with an AI GM. You play Brannoc, a half-orc fighter, at the mouth of a flooded mine.

Narrator: Black water fills the shaft up to the third rung of a rotted ladder. Something bobs against the far wall: a lantern, still lit, bumping gently in the dark. What do you do?

You (speaking): "I wade in up to my knees and reach for the lantern with my sword so I don't have to put my hand in the water."

Narrator: That's a careful reach on slick stone. [Dexterity check: 14, success] You hook the lantern's handle on your blade and lift it clear. The light shows scratches on the inside of the glass, like someone tried to write a word with a fingernail.

Notice what happened: you never said "I roll Dexterity". The game decided a roll was needed, rolled it, and the narrator built the result into the scene. That's the referee job you no longer have to do.

Habits that make solo play better, whatever method you use

• Be specific about intent. "I search the room" gives the narrator (human, AI or oracle) little to work with. "I check under the bed for a loose floorboard, because the letter said he hid the key" gives a clear yes-or-no moment.
• Say your character's traits out loud. If your race gives you darkvision or your class has a special ability, mention it when it applies: "I use my darkvision to look down the tunnel." An AI GM sees your sheet's scores, but stating the ability you're using gets the best result.
• Restate key facts after a break. If you come back to a long adventure, a one-line recap ("I'm still carrying the scratched lantern and I owe the ferryman a favour") keeps any narrator on track.
• Let failure happen. Solo games are more memorable when you don't fudge. VoxDungeon is built as a permadeath roguelike, so death is final and your next character starts a new tale. That's what gives the danger weight.
• Keep sessions short at first. Twenty or thirty minutes is a good first session with any method. Stop on a cliffhanger and it's easy to come back.

What's free and what's Premium in VoxDungeon

If you try the AI route here, the free tier gives you 5 games a day of up to 50 turns each, with full voice input, AI narration (with a daily cap on spoken narration), server-rolled dice, and every race and class. Premium ($4.99/month) removes the narration cap, adds a narrator voice picker, unlocks Quest Mode (adventures with a set goal, a villain and a real ending you can win or lose), and lets you host co-op games for friends. You don't need Premium to play a full solo adventure.

Which method should you choose?

• You like rules, dice and tinkering: oracles and random tables. Expect to do the bookkeeping yourself, and enjoy it.
• You like writing and introspection: a journaling game.
• You miss the conversation at the table (talking to NPCs, being surprised, fights that move fast): an AI Game Master.

Plenty of solo players mix them, using an AI GM for quick evening sessions and a journal for the downtime between adventures. There's no wrong answer. The only real mistake is waiting for a group to come together before you play at all.

FAQ

Do I need to know the rules to play without a GM?

With oracles you'll want a rulebook handy. With an AI GM you don't: the game asks for rolls when they're needed and tracks your HP, armour class and inventory for you.

Can I play on my phone?

Yes. VoxDungeon runs in a mobile or desktop browser. Voice input needs a browser with speech recognition (Chrome, Edge and Safari work); in Firefox, just type your turns.

Is it really solo, or are there other players?

Solo by default: one player, one AI Game Master. Co-op is available if a Premium player hosts and invites you.

What happens if my character dies?

Death is permanent for that character. You roll up someone new and start a fresh tale.
