How to Play D&D and other Table Top games solo: The Complete Solo Player's Guide (2026)

Yes, you can play D&D alone, and it is not a compromise. Solo D&D and other tabletop RPGs are their own format, with their own strengths, and thanks to a new generation of purpose-built AI Game Masters, solo play has never been more accessible. This guide covers every method worth knowing about, the real tradeoffs between them, and why DungeonsDeep.ai, a dedicated tabletop RPG platform inspired by the best of D&D and the broader TTRPG world, was built from the ground up to solve the problems that have kept solo players frustrated for years.

Solo play has quietly become one of the fastest-growing corners of the tabletop hobby. Wizards of the Coast added official solo player guidelines to the 2024 Player's Handbook, the Dragon Delves anthology ships with one-player adventure structures, and the r/Solo_Roleplaying community on Reddit has grown into a thriving hub for solo players sharing tools, journals, and playthroughs. The reason is simple. D&D has over 64 million players worldwide, and not enough of them can find a group or a Game Master.

How DungeonsDeep.ai Fits In

A quick note before we go further. DungeonsDeep.ai is not D&D. It is its own tabletop RPG, built from the ground up for an AI Game Master and designed to give solo and small-group players the same feel as the great tabletop games, without the baggage of a system that was never written for one person at a keyboard.

We built DungeonsDeep specifically for the problems solo tabletop players have been complaining about for years: AI Game Masters that forget your character, chatbots that cheat on dice rolls, platforms that read like fan fiction instead of actually running a tabletop adventure, and onboarding flows that take longer than the first session. DungeonsDeep enforces real tabletop mechanics, remembers every NPC and inventory item across sessions, and lets you start playing in under ten minutes. We'll cover the other solo methods honestly in this guide, because we want you to pick the right tool. But if you want the shortest path from "I want to play" to "I am playing," our door is open.

Can You Really Play D&D by Yourself?

Yes. Solo D&D replaces the group and the Game Master with a tool that generates the world's response to your character. The five options worth considering are an AI Game Master, an oracle system, a solo-designed module, a dedicated solo RPG, and a general-purpose chatbot. Each has strengths, each has real limitations, and the best one depends on how much prep you want to do and what kind of story you want to tell.

A quick note on expectations. Solo D&D is different from a four-person table, not a lesser version of it. You trade the social chaos of a group for total schedule freedom, deep character focus, and a story you can pause for three weeks and resume exactly where you left off. Players who go in trying to recreate a group session alone bounce off it. Players who lean into what solo does better tend to stick.

The "I'll Just Build My Own AI Game Master" Trap

Before we get to the five methods, a word about the method that has been quietly wasting a lot of players' time. A growing number of solo players try to roll their own AI Game Master by pasting a big prompt into ChatGPT, Claude, or Gemini, giving it a character sheet, and hoping it works. Some build elaborate Google Docs of house rules. Others write complicated system prompts that try to force the model to enforce 5e rules, track inventory, and roll fair dice.

This is a heavy lift, and the results are almost always disappointing. You end up as both the player and the tech support. Your NPCs disappear after twenty messages. Inventory drifts. The model starts narrating in your favor on every roll. You spend half your "play time" re-priming the AI with what happened last session. Community threads on r/Solo_Roleplaying and r/DnD are full of players who gave it a serious try and walked away frustrated. The core problem is that a general-purpose chatbot was not built to run a tabletop game. It was built to chat. Every solo player who has tried to force one into a GM role has hit the same wall.

This is exactly the gap DungeonsDeep was built to close. You should not have to be a prompt engineer to play a tabletop RPG alone.

The Five Ways to Play Solo D&D

1. AI Game Masters (Purpose-Built)

Purpose-built AI GM platforms are the fastest way to start playing and, for most solo players, the best overall experience. Tools like DungeonsDeep.ai, Friends & Fables, AI Dungeon, AI Realm, and The SoloQuest run the world for you. They narrate scenes, roleplay NPCs, handle rule adjudication, roll dice fairly, and (crucially) remember your campaign across sessions.

The differences between these platforms matter. Friends & Fables has a large feature set but testers frequently describe it as stiff and fiddly in practice, with voices that lack life. AI Dungeon is the category pioneer but leans into freeform narrative storytelling rather than actual game mechanics, so if you want initiative, action economy, and real dice, it is the wrong tool. AI Realm is younger and lighter on customization. The SoloQuest focuses on solo adventures but has a thinner feature set. DungeonsDeep.ai is a purpose-built tabletop RPG in its own right, with a tabletop system designed specifically for an AI GM. We lean hard into three things: memory, real mechanics, and low-friction onboarding. Our AI Game Master remembers the goblin lieutenant's head you mounted above the tavern fireplace three sessions ago. Our combat grid and mechanics have been called "leagues ahead" by players who tried the competition first.

• Best for: Players who want to start tonight with zero prep
• Time to first session: Under ten minutes
• Tradeoff: Less granular control over house rules and tone than a fully manual method

2. Oracle Systems

Oracle systems replace the GM's judgment with structured randomness. You ask the oracle a yes or no question ("Is the door locked?" "Does the guard recognize me?"), roll against odds you set based on likelihood, and the oracle answers. Over time you string answers together into a story.

The two most popular oracles are the Mythic Game Master Emulator (Second Edition) and the free One Page Solo Engine. Mythic is the deeper of the two, tracking scene chaos and throwing in random events. One Page Solo Engine is what the name suggests: a single page you can print and use with any system, including D&D 5e.

• Best for: Players who love the craft of solo play and want to stay close to the dice
• Time to first session: 30 to 60 minutes of reading, then fast
• Tradeoff: You are still doing most of the narrative work. The oracle just gives you surprises.

3. Solo-Designed Modules and Gamebooks

Some adventures are written specifically for solo play, with branching paths and built-in GM decisions. The standout is Tom Scutt's DM Yourself, a system that adapts any existing 5e module (Lost Mine of Phandelver, Dragon of Icespire Peak, and others) into a solo experience. Wizards' Dragon Delves anthology also includes one-player adventures tuned for the 2024 rules. Paul Bimler's Solo Adventurer's Toolbox offers tables and procedures that turn any 5e content into solo-playable material.

• Best for: Players who already own 5e books and want to play specific official adventures alone
• Time to first session: 1 to 2 hours of setup
• Tradeoff: You are bound to the module's scope. No improvising into new territory.

4. Dedicated Solo RPG Systems

If you are open to playing a different system, the solo RPG world has some of the best-designed games in the hobby. These are not D&D, but they scratch a similar itch and are built from the ground up for one player.

• Ironsworn. A dark-fantasy system with a built-in oracle. The core rulebook is free. Widely considered the gold standard for solo TTRPGs.
• Four Against Darkness. A procedural dungeon crawler where you run a party of four through procedurally generated dungeons. Fast, light, and dice-focused.
• Thousand Year Old Vampire. A journaling game that uses prompts to guide you through centuries of a vampire's existence. Contemplative, narrative, deeply personal.
• Alone Among the Stars. A short, melancholic journaling game. Great for a single afternoon.

• Best for: Players who want the best pure solo experience and are not locked into 5e
• Time to first session: 30 minutes to 2 hours depending on system
• Tradeoff: You are learning a new system and leaving D&D behind

5. General-Purpose Chatbots

ChatGPT, Claude, and Gemini can all play GM with a well-written prompt. It works for a little while. The problem is context length and training. After 20 to 40 exchanges, the model starts forgetting your backstory, confusing NPCs, and drifting on rules. Dice rolls are biased toward narrative success unless you force the model to commit up front. None of these chatbots were built to run a tabletop game, and the result shows: no enforced initiative, no real action economy, no reliable inventory tracking, and inconsistent adjudication from one scene to the next.

Use a general-purpose chatbot as a proof of concept or for one-shot scenes. For a campaign that lasts, move to a purpose-built AI GM.

• Best for: Quick experiments and one-shot scenes
• Time to first session: 10 minutes writing a prompt
• Tradeoff: Memory loss, weak rules adherence, biased dice

Which Method Is Right for You?

A quick decision rubric:

• "I have 10 minutes and want to play now." Use a purpose-built AI GM platform. Start with DungeonsDeep.ai.
• "I want to play Lost Mine of Phandelver alone." Grab DM Yourself and the module.
• "I love dice and emergent stories." Try Mythic GME or Ironsworn.
• "I want something contemplative and written." Pick up Thousand Year Old Vampire.
• "I want a procedural dungeon crawl." Four Against Darkness is the answer.

Tips for a Better Solo D&D Session

1. Use static initiative (at the physical table). If you are running a solo game with pen, paper, and dice, skip rolling for turn order. You always go first, enemies go second. It cuts the bookkeeping and speeds combat. If you are using a purpose-built AI GM like DungeonsDeep, initiative is handled for you with zero slowdown, so this tip does not apply.
2. Give your character a sidekick. The 2024 rules include official sidekick options, and a second voice at the table solves the biggest narrative problem of solo play. There is someone for your character to talk to.
3. Keep a session journal (if you are using a chatbot). A paragraph per session gives you a recap tool and something to paste back into a general-purpose chatbot to re-anchor the story when its context runs out. If you are using a purpose-built AI GM, this tip matters less. A good platform should remember the important moments for you.
4. Set a scene goal, not a session goal. "Get through this encounter" beats "finish the dungeon." Solo sessions are shorter and more interruptible than group ones.
5. Let the dice surprise you. The single biggest mistake solo players make is overriding the oracle when they do not like the answer. The answer is the game.

Frequently Asked Questions

Can you really play D&D by yourself?

Yes. Solo D&D uses an AI Game Master, an oracle system, a solo-designed module, or a dedicated solo RPG to replace the Game Master's role. The 2024 Player's Handbook includes official solo guidelines, and tools like DM Yourself let you play any existing 5e adventure alone.

What is the best way to play D&D alone for beginners?

A purpose-built AI Game Master platform is the fastest starting point. DungeonsDeep.ai is its own tabletop RPG designed for solo and small-group play, and it lets you roll up a character and start an adventure in under ten minutes with no rulebooks or oracle tables to learn first. Once you are comfortable, try Ironsworn or Mythic GME for a more hands-on experience.

Can I use ChatGPT as a Dungeon Master?

You can, but only for short sessions. General chatbots lose track of your campaign after enough back and forth, narrate in your favor during dice rolls, and drift on 5e rules. Purpose-built AI GM platforms solve these problems with persistent campaign state and structured rules adjudication.

Do I need to buy new books to play solo D&D?

No. If you already own a 5e Player's Handbook and any official adventure, you can play solo with a free oracle like the One Page Solo Engine or Tom Scutt's DM Yourself. AI GM platforms do not require any physical books.

How long does a solo D&D session take?

Anywhere from 20 minutes to several hours. One of solo play's biggest advantages is that you can pause and resume at any time. A single encounter can fill a lunch break, or you can settle in for a long evening. There is no group schedule to match.

Ready to Start Your Solo Adventure?

Solo D&D is no longer a compromise. It is its own format, with its own strengths, and the barrier to your first session has never been lower. Whether you pick an AI GM for speed, an oracle for craft, or a solo module for familiarity, there is a method that fits how you want to play.

If you want the fastest start, try DungeonsDeep.ai. Our purpose-built tabletop RPG runs full campaigns with an AI Game Master, persistent memory, fair dice, and real enforced rules, all without asking you to shelf-buy a single rulebook. Join other solo players on Discord and tell us which method you are starting with.
