INdex CArd RPG: The Juggernaut

Index Card RPG (ICRPG) represents the accidental, intuitive, inevitable result of countless game sessions and legendary tales. It wasn’t invented so much as discovered. It was hiding right there all along, in sheafs of paper, wobbly drawings, and bags of dice.


Since its first release as a series of silly Sharpie drawings in 2016, ICRPG has become an unstoppable best-seller and served as a rallying point for a vibrant, creative community of players and creators in several countries, digital platforms, and languages.


It has helped to unlock the potential of gamemasters and clumsy dreamers. That was always the hope; to push people ‘over the edge’ of their doubts and hesitations; to remind them of the endless landscapes in their own imagination, and send them tumbling in with reckless enthusiasm.

So if you’re looking to take advantage of ICRPG’s indomitable DIY spirit and its easy-to-use system for your games, you’re in the right place!

a d20 system you command


Viking Death Squad is a game of desper- ate odds and thundering drums. It’s a world of burning iron and power armor, of supernatural darkness and technolog- ical terrors, of heavy metal and lightless starships.


Urth, the year is 10,191. A vast empire called The Infinitum , also known as the War Pigs, has left all in ruin in its endless quest for Immortality and supreme pow- er. To make things worse, Lucifer, Prince of Darkness has joined the fray, using the chaos to prey on mankind from below the surface.


Like all great role play, Viking Death Squad (VDS) is all about telling stories and leg- endary battles. What adventures lie ahead in such a desolate world? Who will remain to rebuild the solar system when the fires finally cease? Can the armies of hell be used against the endless War Pigs?


Let’s play to find out.

  • Playing in Clockwise Turns: This has been a staple in board and card games for generations. You and your group will rejoice as this simple foundation of play streamlines numerous aspects of any session.

  • Effort Dice: The wild variety of things that get players rolling dice are compressed here into simple categories of EFFORT, each using its own die type.

  • Targets: ICRPG combines all roll targets into a single number at the table. Furthermore, there are just a few numbers that even need be considered. This will vastly speed up and simplify any game, and give players a clear vision of challenge.

  • Clean STATS: There are no skills, derivative number formulae, feats or talents here. This game system just uses a character’s six core STATS to call for rolls, make ATTEMPTS, CHECKS, and generally be awesome.



The average GM is a chronically overloaded creative beast. This book takes a bold stance to disrupt many sacred traditions for the GM... dare to enter a session seat-of-the-pants! Trust hex rolls, loot rolls, random NPCs, enemy tactics dice and more to make a legendary session happen on-the-fly. Are you ready for the madness?

CROWN and SKULL includes an in-depth Game Master's Guide, from modifying, inventing, and running enemies to dream states and esoteric considerations of style and story. Next level. You've got this.
