This jam is now over. It ran from 2024-12-01 08:00:00 to 2025-01-01 20:00:00. View 28 entries

Join us during the month of December to make something- anything- using Decker, the multimedia sketchpad that's also a program for your computer!

Will you:

  • Make a visual novel?
  • Write a poem?
  • Create a digital activity placemat?
  • Write a utility that makes your life easier or more delightful?
  • Compose a Zine about a topic you love?
  • Build something new and wonderful?

The possibilities are limitless!


Be sure to check out previous Decker jams for inspiration!

Rules:

  • Submissions must be made using Decker, and provided as a web-playable HTML export. Sometimes web-decker is a bit slower than native-decker; don't wait until the last minute to test in a browser!
  • Submissions should be original work. Dusting off an old unfinished project is OK; we run on the honor system here.
  • Submissions must not make use of so-called "generative AI" tools such as image models or large language models.
  • Making use of pre-existing Public Domain or Creative Commons assets is fine, as is using materials shared on the Decker community forum and materials distributed with Decker itself.
  • Feel free to collaborate in teams, submit multiple decks, or both.
  • Including or referencing chickens is completely optional, but always appreciated.
