This year, for the fourth year in a row, we're celebrating the entry of new works into the public domain with our public domain game jam: Gaming Like It's 1926. We're calling for submissions of games inspired by or making use of material that entered the public domain this year.

We're approaching the halfway point of the jam, so there's still plenty of time to sign up on itch.io and start working on an entry! You don't need to be an experienced game designer to get involved — entries can be as simple as a page of instructions for a roleplaying game or rules that require a normal deck of playing cards. If you want to try your hand at making a digital game, there are easy-to-use tools out there like Story Synth, created by our partner in running these jams, Randy Lubin.
