You can find the Carta System here!

Think of this as a basic set of rules that you can use as a framework to build a solo TTRPG. We supply the rules and you supply the ideas!

Carta games, like our Into the Glacier and Apex Predator, are exploration games, but we're curious to see what else they can be! If you make a game using this system, please link it in the comments below or tag @CatlingGun on twitter so we can see what you've made!

The base idea is that players lay cards out in a grid , and then turn them over one at a time, exploring prompts and mechanics as they do. The game is a sort of boardgame / storygame hybrid, where players explore journaling prompts by physically moving their marker from card to card and looking up the results. It can have a definite goal, making it more boardgame-like, or it can be more nebulous and story-focused.

Let's Discover!

This SRD was built for stories about solitary discovery. GMless Multiplayer rules can definitely be added, but the default ruleset is a single-player one. You might want to tell stories about:

  • Exploring a classic-style dungeon in search of treasure
  • Wandering around a city and seeing the sights
  • Being pursued through a haunted mansion
  • Searching an alien planet for survivors
  • Just playing Monster Hunter, I guess. That's what I did.

Welcome to the Carta Jam! 

The Carta SRD is a system you can use to create single-player games about exploration and discovery. Now that we've finally published the base rules, we're hosting a jam to give everyone the chance to show off their hard work!

The rules are straightforward:

  • Your game should feature the Carta SRD in some way. It should be, in whole or in part, a Carta game.
  • Your game should NOT feature any content that is bigoted, cruel, or harmful to other people. No racism, xenophobia, ableism, transphobia, homophobia, or any other behavior that contributes to the oppression of others
  • You should absolutely charge for your game. 
  • Any game material is fine. Because this is an SRD, you'll probably end up making a game, but that doesn't mean you couldn't use Carta to make a dungeon for another system, for example. 
  • This SRD is pretty new, so your game will probably be new, but it doesn't have to be, as long as it meets the other criteria.
