1) "Threes" is part of the theme - it's our "Technical Theme," which is released early to help you get in the mindset of what you might be making, what tools you might be using, what interesting limitations you can put on yourself, etc. We will be revealing the "Creative Theme" at the jam's kickoff in person and online, which is to be decided! People who are donating to PIGSquad are voting on that one right now via https://www.patreon.com/posts/vote-on-3-button-28329869. Who knows what it will be? ;)
2) You do not need to be from Portland to participate. We welcome submissions from all over, but also very much encourage those participating to follow along by seeing what people are working on via our Twitter and by chatting with other jammers via our Slack! You can find those channels here: https://pigsquad.com/community
