Overview

Rules

As long as not otherwise stated, the solution is a 8 characterstring only using the 26 lowercase english letters
The solution is normally not a word. It's just 8 random characters
Sometimes it is possible, that the input can lead to several possible solutions. If you find <5, try them. Otherwise you made a mistake
Don't try to brute-force
Don't try to hack the server or use other ways to bypass the intended usage
Please don't produce too much load on server. If there is a large image, just download it once.

Types

Source

The solution can be found in the website itself (although the name implies so, the sourcecode isn't needed always, and won't help always)

Riddle

The website shows a riddle to be solved to get to the solution. There are no hints hidden elsewhere. Your task is to interpret the given text / images correctly. (Images also don't contain hidden content. Everything you need is visible by default)

Images

Here the solution is hidden in the image.

Misc

Other problems. The caption / description will give a hint.

Crypto

In these problems, the solution was encrypted in some way. Just like the riddles, all necessary information will be visible. The encryption or decryption key will be available or can be bruteforced with very few tries (~100). Only <5 possible encryptions will match the required format. The encryption algorithm will either be stated in the problem, or is obvious by the given values.

Guess

Here the solution will be a word, a number or similiar that you really have to guess. E.g. if you are given an image, the solution will be the object in the image. Again, you won't have to guess many words. If you understand the image, it's obvious. Only use lowercase letters and no spaces etc. (even if the name would have some)
