/CTF-Game-Challenges

A curated list of Game Challenges from various CTFs

CTF Game Challenges

I have been learning about game hacking recently and the best way I could find legally to practice is by playing CTFs.
But the difficult part is finding out the Game challenges from previous ctfs.

This list includes game challenges I encountered while playing ctfs and reading writeups.

Also just FYI as some of the gameservers are offline and there is no clear way to set it up or the developers have not opensourced it we can't play it now.
