What is Sinister Jam?

Sinister Jam is a unique game jam series consisting of 7 events, each inspired by one of the Seven Deadly Sins from the Bible. In every event, participants are challenged to create games based on the sin chosen as the theme, turning these timeless human flaws into engaging and creative gameplay experiences.



Theme

Theme: Pride

Pride is one of the seven deadly sins, symbolizing excessive self-confidence and arrogance. It’s the belief that one’s importance, power, or perfection is greater than anyone else’s.
