About

Achtung, die Kurve! (also known as Curve Fever) is a freeware multiplayer snake-style game in which two to eight players leave continuous trails and try to force opponents into a wall or a trail, using only left/right turning. Quick Curver is a hardware-accelerated implementation of Achtung, die Kurve! built in C++20 and Qt 6 with a Material Design interface. It supports local and online multiplayer plus bots, and runs on Windows and Linux, built from source (with an Arch Linux AUR package and a Nix flake available) or installed from a precompiled Windows release.

How it differs from the original

Adds bots and collectible items on top of the original two-button curve-trail formula, and includes an offscreen/headless mode for running a dedicated server without a GUI.

Getting started

Compile it from source (a C++23-capable compiler and several Qt 6 modules are required) or install the precompiled Windows release, then run the built executable. For online multiplayer, the host shares their port and other players connect to that address; those behind a firewall or router may need port forwarding or hole punching, and the host can tweak a network update rate setting to trade responsiveness for smoother performance.

What you need to run it

No original game files required, according to the project's README.
