What is an in-game app?

An in-game app is a native desktop app that can track and use in-game events/stats, all in real-time. It gives you endless creative freedom to build rich, immersive experiences within your favorite games.

These apps live both on your desktop and in-game, as an overlay, unlocking infinite possibilities to experiment and create.


So as you see, the Matchups Hackathon is all about matching between designers and app developers - to create fantastic apps that look and feel amazing. So right now, we are looking for awesome UI Designers who are passionate about AAA gaming, to join forces with in-game app creators.

If you can realize the true value of an app, if you can make it shine by creating the perfect user experience for it - then hop over; you’ve come to the right place.

Hurry up and join! Start mingling and networking with our almighty in-game app developer community – over 8K creators strong. Compete for a $5,000 prize pool and get to design beautiful experiences for thousands of gamers to enjoy daily.
Just fill out this form by July 25th and we’ll let you know if you’re one of the lucky designers chosen to participate. We’ll add you to a special Discord channel and give you all the info you need.
