Catjam

The Concatenative Game Jam, or “Catjam” for short, is an annual game jam hosted by the Concatenative Discord. The latest event can be found at jam.catlang.social.

The idea is to have fun making a game with a catlang. We’re pretty inclusive about our definitions of “game”, “catlang”, “fun”, and “with”.

2025

Catjam 2025 runs from July 4 to September 1.

2024

Catjam 2024 officially ran from July 11 to August 31.
