Play the hardest riddle game on the internet.
Each level contains some sort of hint to get you to the next level. Getting to the next level could be achieved by finding the right spot on the picture to click, by changing the text in the URL or by discovering the username and password to get through.
Sometimes you have to turn to resources outside of NotPron including Google or even using an image editor. The riddle gets progressively harder, which makes it all the more satisfying with each correct answer. The only way to save your progress is to bookmark the latest level. The creator also recommends keeping a note of the solution to each level.
