Summer is upon us. The weather is hot, but pixels are cooler than ever. Pack your bags with swim trunks, mosquito repellent, animated GIFs, plenty of snacks, and, of course, your favorite multimedia sketchpad, Decker.

Join us during the month of July to make something- anything- using Decker!

Will you:

  • Make a visual novel?
  • Write a poem?
  • Create a digital activity placemat?
  • Build an arcade game?
  • Write a utility that makes your life easier or more delightful?
  • Compose a printable, foldable zine about a topic you love?
  • Build something new and wonderful?

Maybe even something that involves chickens? It's your call! For extra inspiration, you can check out lots of interesting games, toys, zines and visual novels made with Decker by searching for the #decker tag here on itch.

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.
