This is not-snc, aka 'nsnc'. It has hidden puzzles, the solution to most of which look like "nsnc{solution}". There are many different types of puzzles. Some puzzles are hidden within the pixels of a comic, others are in a file appended to the image, and still others are hidden in even more secret locations. Enjoy discovering the solutions! Submit your solutions in a POST request to /puzzle/[comicid] with the parameter solution=nsnc{your_solution}
There used to be a small reward hidden on the website. Someone claimed it though!
