This jam is now over. It ran from 2020-10-24 23:59:00 to 2020-10-25 02:30:00. View 17 entries


Yrgo - Game Creator is hosting its third annual Zero Hour Game Jam. We will once again start in the middle of the night at 2 AM work for one hour and then daylight saving time will set the time back to 2 AM thus making the event zero hours long. 

The theme will be announced at our itch.io game jam page about 5 minutes before the jam starts. Five minutes for design and one hour of build time. You are allowed to use existing assets (images, models, sound and so on).  You are not allowed to use ready game templates. You are allowed to create a blank project and pre-load any program you might need (unity, photoshop and so on). 

Once time is up you will have 30 minutes to submit your game (if the server time differs we will adjust the time for submission).  You are allowed to add screenshots and make a trailer after the time has run out. You are also allowed to fix up to two game breaking bugs after the timer runs out.

This year the event is online only.
