Grey Cells


Grey Cells is a tabletop role-playing game of detective fiction. Through choice or circumstance, your group of investigators are embroiled in criminal conspiracies that only they can stop.

  • Unique talents and powers to set your investigator apart and help them solve even the most fiendish cases.
  • Simple mechanics to gather information and resolve conflicts.
  • Many valid approaches to conducting an investigation, ensuring that even if you hit a dead end there'll always be another way to proceed.
  • Tools to create your own mysteries and suspects, each with their own easy to understand motivations and secrets. 
  • Guides on how to tailor your game to match your favourite crime  fiction genres: Cozy, Great Detective, Hard-Boiled, Police Procedural, or Thriller.

As a Poirot fan of course I'm intrigued. I'd love to get a sense of the basic mechanic style - Gumshoe? PbTA? d20? Percentile? A new approach?

Looks like right now, this is PDF only. Will it ever be available as a POD softcover and/or hardcover?

Agreed! I always like to see a preview that includes the core mechanics (and an overview of character creation, if possible) before I invest in a game.

This description has Beat Cop twice in the list of six backgrounds. What is the actual sixth background?

Thanks for answering this! Clearly I needed to do just a little more proofreading.

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.
