Card games engine – Bang, Prší and UNO

I wanted a simple way to play my favorite card games with friends online without forcing anyone to download heavy apps, create accounts, or deal with annoying ads. So, I built this.

It’s a lightweight, fast, browser-based card game hub. Just create a room, send the invite link to your friends, and start playing immediately.

What can you play?

Currently, the engine supports a few classic modes:

Bang! – The chaotic Wild West shootout. Figure out who is the Sheriff, who are the Outlaws, and who is the lone Renegade. Grab your Colt, hide behind a barrel, and try to survive the crossfire.

UNO – The ultimate friendship destroyer. You know the drill: +4s, reverses, and the inevitable rage quits.

Prší (Mau-Mau / Crazy Eights) – A fast-paced European classic. Change suits, force your friends to draw cards, and be the first to empty your hand.

The "Fullscreen" Experience

You can test out the game right here on this itch.io page via the web player above.

However, since card games require some screen space for your hand and the table, it plays much better in full screen! To get the best, uncropped experience, either click the redirect button inside the game menu, or just jump directly to my main server here:

I’m actively working on this project and hosting the servers myself (accually on my rasberypi). If you run into any bugs, have ideas for improvements, or want to suggest new rules/games to add, let me know in the comments below. Have fun!

Build Your Own Game!

Did I mention this is actually a custom-built engine? You can use it to create your very own card games! Right now, the easiest way is to write your game logic in Java – the API is ready, you just have to send me your code so I can plug it into the server. Support for JavaScript/TypeScript and Python is also running under the hood, though the documentation for those is still a work in progress. My ultimate goal is to add a feature where you can just upload your custom game scripts directly to the server yourself. If you're a fellow dev and want to tinker with it or build your own ruleset, hit me up!
