One Page Solo Engine


One Page Solo Engine is a minimal, all-in-one toolkit to play your favorite tabletop RPGs without a GM.  It was designed to be incredibly concise and minimalistic, but still have all the essential tools required to play a game without a GM.  It provides tools for scene framing, action pacing, unexpected results, random events, answering questions, and generating setting-neutral content for things like quests, NPCs, dungeons, and more.

There are a great many excellent tools out there to run a solo RPG game, but I always found that many of them are overly complicated.  You shouldn’t have to read a dozen pages of rules and make 10 dice rolls just to determine what the guards in a room are doing.  One Page Solo Engine is designed to provide every tool needed to run a solo game using any game system while using as few words as humanly possible.

One Page Solo Engine is free to use and share.  We hope you will use it to experience the many exciting adventures solo roleplaying has to offer.  It is released on the CC-BY-SA license, so it is free to use, adapt, and include in your own works, even commercially, as long as you provide credit.

Check out Inflatable Studios on for an online implementation of these rules that allows you to type in your adventure as you play and export your adventure log to share with others.

What does the T card rank mean?

I guess I can play this using a Tarot deck without trumps/major arcana, or using dice, but I can't but wonder what kind of deck this was designed for.

Sorry, I've just understood that T is a notation for 10.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
