Global Game Jam® 2023

At coherence we have always considered it our mission to bring easy and accessible multiplayer game development to everyone, and to connect people through meaningful experiences. To make sure coherence works well even for small teams, we’ve made game jamming the heart of our culture. Now it’s time to test coherence on a truly global scale - that’s why we’ve teamed up with Global Game Jam® 2023 as an official sponsor!

To appreciate the scale of GGJ® - their record year saw participants from 934 locations in 118 countries, who created an amazing 9,601 games during a single weekend. As far as live product tests go, we think you’ll agree it’s difficult to find anything more challenging.

The Challenge

As if creating games within a 48-hour time window was not hard enough, we're inviting you to take part in a challenge - create an online multiplayer game using coherence! To ease your mind - we've already held a full coherence game jam. Check out the live stream recording of game presentations.

$10,000 Up For Grabs

In addition to the personal gratification of giving yourself this extra challenge, we’ve decided to reward the most innovative multiplayer game ideas with $10,000 worth of prizes! If that sounds like something for you, please register your interest below.
