Let's make Puzzle Games!
The Creative Theme is
"Chain Reaction"

Join us in our Opening Event on June 13th and Closing Showcase in person & on stream.

  • Make a game that introduces a problem or series of problems for your player to solve, whether it's about number patterns, shapes, a mystery narrative, building a contraption, escaping a room, or whatever else you can think of!
  • Disobey, Wasdonaut, Jimi can not read, Tumbling Tunnelings, and Kerners! are great examples of past PIGSquad community projects featuring puzzles.   

Jam Schedule:

We will be hosting streams and other online activities to support jammers in meeting and sharing. This list will update over time. All times listed in Pacific time zone.

Rules & More Details:

  • Non-Portlanders are welcome to participate remotely.
  • Follow PIGSquad on social media channels for consistent updates on team forming, events, workshops, and other opportunities. Tag us on Bluesky, Mastodon, Instagram, Twitter, etc for a share!
  • If you'd like to contribute to the jam theme, suggesting & voting is exclusive to our Patreon members - learn more here!
  • All participants, in person or remote, must follow PIGSquad's Code of Conduct. As a general rule, please keep entries "PG-13" or younger. No nsfw content.
  • Games made with or featuring Generative AI (large language models, stable diffusion, AI image/art generators) will not be accepted. The purpose of these jams are to encourage collaboration with other real people that share common interests and/or push yourself to learn new skills.
  • Do not police submissions or make fun of / talk down on jam submissions or jammers' ideas in PIGSquad channels or otherwise. Our goal as a community is to uplift creative collaboration and learning.
  • We encourage you to jam with new people or on a team, but it is not required. We will be providing resources for team forming at the jam kickoff and throughout the jam timeline for those who want to jam based on the theme.
  • This jam is not a competition and is not judged.
  • Please don't crunch! We host game jams over extended periods of time and like having open conversations with jammers about scoping projects to encourage a healthy outlook on creative production schedules. If you need help scoping, please reach out.
  • Jammers retain full ownership of the games they make during PIGSquad jams.
  • Late submissions or submission updates can be accepted, just get in touch with an organizer. Please note that games must be updated on your itch page multiple days before the showcase if you'd like the updated version of your game to be played at the jam showcase - we do not take requests for downloading game updates within 48 hours of the online showcase. You are welcome to update your game at any point after your jam submission regardless of when the showcase is.
  • Sticking to the theme is encouraged, but not mandatory - if you have an idea you'd like to pursue that branches from the theme, we encourage you to make that game!
  • We will be removing spam submissions from the entries that are clearly submission bombing to multiple jams or otherwise.
  • Thanks to Corwyn for creating our header art! Check out his work here.

We have a new "How To Jam" guide if you'd like some great recommendations for
how to spend your time and make the most out of the event :)

Summer Slow Jams:

Each summer, game makers get together to make a game project with friends and community members in a few weeks! Summer Slow Jams is a collection of game jam events happening once a month this summer, providing structure and networking opportunities for creatives in Portland and remote participants. Participate in a jam to finish a creative project, learn new things, meet new people, and share your work!

Creative themes are delivered during each kick off event then shared online, and developers are able to showcase their game jam projects at each closing event in Portland, OR (or online). In between the dates of the kick off and closing showcase, you are encouraged to meet up with others using online channels to complete a game over whatever in-jam time period you see fit: take it slow if you need!

For more information about how to participate in Summer Slow Jams, visit pigsquad.com/summerslowjams. Summer Slow Jams this year include Puzzle Games in June, Party Games in July, and Parody Games in August.

Share with the hashtag #summerslowjams and PIGSquad will reshare screenshots, video uploads, and blog posts of jam games while you're working on your games!
