The Jack Hack

A Role-Playing Game of Victorian Villains 

Developed by John R Davis

(Dogs Dinner Games) 

Based on The Black Hack by David Black 

You were once quite worthy fellows. Something terrible happened and you hit rock bottom. Were it not for a mysterious benefactor you would have died. Maybe you would have been better off that way. Your life is one long fight to survive in the twisting, dank alleyways of Whitechapel area of London. 

And now rumour has it there is a serial killer on the loose. 

Welcome to the ‘Jack Hack’.

The Jack Hack is an OSR inspired game using the Black Hack system by David Black. A copy of the Black Hack is needed to play the Jack Hack

The Jack Hack is a game of trying to beat the odds in the depravity of late Victorian London. It has particular focus on the Whitechapel area just before, and around the time of the infamous Jack the Ripper murders.

CAUTION: By its very nature this game features somewhat adult themes. There is some gore. There is some sex. There is Victorian Profanity. Clearly the Whitechapel Murders were a terrible event but the mystery and legend about them is perfect for game creativity.

The game features:

5 new classes:

·         The Broken. Former military tough or pit-fighter, now a shallow shell of a man.
·         The Cokum. A street swindler, hypnotist or mesmerist, false nobility or fake folk hero.
·         The Disgraced. A former doctor, scientist, lawyer, politician; abandoned by friends and family.
·         The Fine-wire. Once master criminal, now mocked by both police and thieves.
·         The Night-Flower. A singer, actress; now working girl unable to rise out from the squalor.


It also features two new usage dice:


The White.

This usage dice represents your ‘outer’ influence, infamy, contacts and place in the Whitechapel area. You can use it to quickly gather information, find a safe house, find a short cut, or anything your group deems relevant. It would be cool if this was a white dice.


The Black.

This usage dice represents the ‘inner’ torment you suffer. You can call on it to complete a task, but the GM can force its use when she (or you) thinks a recent setback may cause you to go into a downward spiral and you need to face your demons. It would be cool if this was a black dice.


The Rest of the book is ‘Welcome to Whitechapel’ and contains lots of random stuff to see, do and suffer! There are many random tables such as:

·         20 things found floating in the Thames.
·         20 things a street vendor may sell you.
·         20 places to wake up the morning after.
·         20 petty criminals.
·         20 words a gentleman wouldn’t call his wife.

There are about a dozen of these in total.

There are also many lists of places to visit, and numerous adventure seeds to start your Jack Hack.

The Whitechapel Murders. Entirely up to you when, and if, and how, they happen.

Do the PCs cause them?

Do the PCs stop them happening!

Do the PCs become the culprits!?

In Development: Future add-ons for the Jack Hack include


Dead London, wherein our rogues have to contend with Invaders from Mars and the Rise of Steampunk!

Carved in Flesh. Which looks at each Whitechapel murder in turn, with added conspiracy/theories linked to a big event nearby at the time (a freak show, an ecclesiastical gathering, etc).

Ripper Fhtagn. Five bodies within an elder sign?. Dark horror including a light sprinkling of mythos, penny dreadful and gothic.

Let me start by saying that the Black Hack has been a great addition to the OSR landscape. A ton of settings to add to a simple and versatile system. The Jack Hack is by far my favorite of those. Late Victorian roleplaying dealing mostly with the seedy [...]

A fun addition to the Black Hack family of games. If gothic horror or Victorian times are your thing you ought to check it out. The game has a neat mechanic, the White Die and the Black Die, for reflecting the outer respectability and inner torment of [...]

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.
