Pocket Dungeon Master
This prompt turns the AI into your personal Dungeon Master: a complete text RPG with quests, dice rolls, inventory, and branching storylines. A full D&D-style adventure with zero prep, playable anywhere.
A full D&D-style adventure in your pocket — the AI DMs, you roll with your imagination.
You are my Dungeon Master for a solo tabletop adventure. Setup: ask me for my character's name, class, and one personality trait — then drop me into [SETTING: a haunted coastal village]. Rules: describe scenes vividly in 3-5 sentences, end every response with 3 numbered choices plus 'or do anything else', resolve my actions with invisible d20 rolls (tell me the roll and outcome dramatically), track my HP (start 20) and inventory silently. Include: an NPC with a secret, a trapped corridor, and a boss with a weakness to discover. If I die, make it epic and offer a heroic last stand. Begin by asking for my character.

What this prompt does
Tabletop RPGs are magical and logistically impossible — scheduling five adults is the real boss fight. This prompt removes the logistics: the AI becomes your Dungeon Master, running a complete adventure with dice mechanics, inventory tracking, NPCs with agendas, and choices that genuinely branch. Solo D&D, no scheduling required.
How to get the best result
Start with a character concept (“a retired pirate turned baker” beats “a fighter”) and let the DM build the world around them. Play in character — describe actions, not just choices (“I slide the barkeep a coin and ask about the cellar”). When the story stalls, say “something unexpected happens” — the DM's chaos button.
Common mistakes to avoid
Don't let sessions run forever in one chat — very long contexts make the DM forgetful (lost inventory, resurrected NPCs). Every few hours, ask for a “campaign summary” and start a fresh chat with it pasted in. And establish dice honesty early: the prompt rolls fairly, but agree whether fudging is allowed.
Try these variations
Genre-swap the engine: cyberpunk heists, cosmic horror investigations, cozy village mysteries — the DM adapts. For the full neon-noir version, the cyberpunk text adventure prompt is this engine reskinned. More in the fun prompts collection.

Frequently asked questions
How is this different from just asking AI to tell a story?
A story is passive; this is a game. The DM tracks your stats, inventory, and HP, rolls dice for outcomes, remembers NPC promises, and lets your choices branch the plot. You're playing, not reading — failure is possible, which makes victory mean something.
Do I need to know D&D rules?
No. The prompt handles all mechanics behind the curtain and explains rolls as they happen (“rolled 14 — that hits!”). D&D veterans can ask for specific editions or homebrew rules; newcomers just play.
Can I play with friends in the same adventure?
Yes — share the chat or take turns giving commands. It works surprisingly well as party play: each person controls their character, the AI DMs everyone. It's the easiest “one-shot night” you'll ever organize.
How long can a campaign run?
Individually, sessions run 1–3 hours before context limits cause forgetfulness. For epic campaigns, use the summary trick: ask for a campaign recap, start a new chat with it, and continue. Players have run 50+ session sagas this way.
