This jam is now over. It ran from 2021-06-24 13:00:00 to 2021-07-31 16:00:00. View 56 entries

After several discussion sessions where the merits and potentials of playing cards in TTRPGS are looked over, the Card Mech Jam is born!


Write a TTRPG in which playing cards play a major role. Whether by hacking a pre-existing playing card game (e.g.: Blackjack, Solitaire, Poker), using playing cards as the main resolution mechanic, using playing cards as prompts, or even any other way that I haven't learned about yet! 
This jam is to explore the possibility space inherent within playing cards.

So, here are some ground rules. 

1.  This jam accepts pre-existing games, as long as they feature playing cards as a major mechanical component.

2. Don't stress too much, this jam is to explore new possibilities, however weird it may be. 

3. This game jam will not accept games that contain harmful, hateful, abusive content.


1. Are Tarot Cards okay?

Sorry! But this game jam is focusing more on playing cards and mechanics that use them!

If you have any other questions or concerns, feel free to contact me on Twitter @zuhayrimohamed. Please use #CardMechJam when discussing this jam and the games you are making!
