Catjam

The Concatenative Game Jam or “Catjam” for short is an annual game jam hosted by the Concatenative Discord.

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.
