One Page Solo Engine v1.6.5

One Page Solo Engine lets you play your favorite tabletop RPGs by yourself, without needing a GM. It does this by answering questions, generating content, and injecting unexpected reactions just like a GM would. Like all tabletop RPGs, the story takes place in your mind with One Page Solo Engine serving as your virtual Game Master for endless adventures.

Here's how you use One Page Solo Engine to play your favorite tabletop roleplaying games by yourself.

Step 1:
Choose your game system (like D&D, FATE, Savage Worlds, Pathfinder, etc.) and build the character you want to play. You will use the rules from your game system like normal during the game; One Page Solo Engine only helps you frame the action and answer questions.

Step 2:
Begin your adventure by rolling a Random Event and then Set the Scene. It's usually good to begin in the middle of the action, so visualize where your character is, what they are trying to accomplish, and what opposes them in this moment.

Step 3:
Learn more about what's going on by asking the Oracle questions. Try to phrase your questions as Yes/No, but you can also get more complex answers by using various Focus tables as well. Any time you have a question that the GM would normally answer, use one of the Oracle actions.

One Page Solo Engine provides general and intentionally vague answers. It's up to you to interpret these in the context of your game. Try to give every result meaning in your story and let the results slowly build the reality of your world.

Step 4:
Play the game like normal using your chosen game system. If you want, you can record your character's actions using the Player Action button and whatever you type in will be added to the story chain.

When the action dies down or you wonder "what next", use a Pacing Move to jump start the action. You can also use a Failure Move when your character fails an important check to add in some unexpected consequences.

Once you've wrapped up the action for the current scene, envision what your character does next and Set the Scene again. Keep playing like this as long as you want!

Step 5:
As you play, you may need to generate some quests to pursue, NPCs to meet, or dungeons to explore. Use the Generator actions to make new content whenever you need it. The Generic Generator is especially useful since it can give you ideas for magic items, space ships, evil organizations, and just about anything else you can think of.

Step 6:
When you're done playing, click the Export button to save your story chain as an HTML file or Plain Text file. You can open the file in a web browser to look back on your adventures, or share it with others online.
