The Cthulhu Hack is a game of investigation; characters battling the sanity-shattering horrors of Lovecraftian gods and monsters. With an elegant dice mechanic and fast, player-focussed gameplay, The Cthulhu Hack is designed for quick and easy pick-up play.

Ordinary people dragged into strange and supernatural situations, The Cthulhu Hack tests muscle, mind and mettle in the face of pernicious cultists and incomprehensible monsters.

Based on the hugely popular The Black Hack and the works of H P Lovecraft, The Cthulhu Hack uses a simple dice mechanic to emulate the dwindling investigative resources available to those intrepid sorts willing to put their lives and reputations on the line in pursuit of the Unmentionable and Unthinkable.

You can:

  • Learn in 20 minutes, explain in 5 minutes, create a new character in 2 minutes
  • Choose from five Classes and 30 Occupations
  • Convert adventures for other investigative horror games on the fly using The Cthulhu Hack's Flashlights and Smokes system to gathering clues and ply contacts for information

Designed for quick and easy pick-up play, simple to explain to new players but with enough crunch to satisfy those experienced with other games.

Check out an example of adventure conversion of The Haunting on the Just Crunch Games website, the rough-and-ready conversion guide for Call or Trail, or give the game a test run with the Quickstart Nocturnal Rites.

No previous experience of the Cthulhu Mythos required! Includes a 3-page Mythos 101 for those unfamiliar with the original tales.

Paul Maclean - "The Cthulhu Hack… at The Breakfast Club we love it!" (Cthulhu Breakfast Club /, at AireCon 4)

Steven Robert - "If you want at least a little bit of butt-kicking, or if you like tossing dice, The Cthulhu Hack is the clear choice." (RPGGeek)

Eric Dodd - "I welcome the appearance of The Cthulhu Hack to the crowded Lovecraftian RPG mantlepiece. If you liked the simplicity of Cthulhu Dark but felt you needed a few more tools and levers to build a game around, without having to track 40 or 50 skills or detailed weapon statistics, then The Cthulhu Hack might be just what you’re looking for." (RPGGeek)

Mike Hill - "The bottom line is that I will actually play this game. I download a lot of projects that never make it off the hard drive." (The World According to CARP)

Simon Burley - "The Cthulhu Hack hit my doorstep today and it's bloody good!" (author of superheroes classic Golden Heroes)

Brilliant! Simple, yet structured enough to keep the game interesting. If you like The Black Hack (and usage dice for resources) and have an interest in Cthulhu Mythos (or want to learn more about it), buying this book should be a no-brainer. It contai [...]

Another fine member of the Black Hack family, this time adding Cthulhu to the mix. This game would work great for any sort of investigative or pulp/noir scenario, though, and not just Lovecraftian horror. The use of the Black Hack "resource die&qu [...]

Original electronic
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.
