This jam is now over. It ran from 2021-10-30 23:59:00 to 2021-10-31 02:20:00. View 47 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.

This is a very stressful event, so no competition or ranking, this is just for fun.

Please note that the server might change time before the jam, so start time might be adjusted.


We are not the only one making zero-hour games, you can also submit your game at our friend's site over at http://0hgame.eu/ (if you like).


Good luck!
