Notpron (originally stylized as Not Pr0n[1]) is an online puzzle game and internet riddle created in 2004 by German game developer David Münnich.[2] It has been hailed by fans, journalists, and Münnich himself[3] as "the hardest riddle available on the internet".[4]
Regarded as one of the first of the online puzzle game genre, Notpron follows a standard puzzle game layout, where the player is presented with a webpage containing a riddle and must find the answer to the riddle in order to proceed to the next webpage. The game had a total of 140 "levels", ranging from 82 "positive" levels, a level "zero", 44 "negative" levels, and 13 "Greek" levels (Ranging from "Alpha" to "Nu"). A couple of the final levels that required interaction with the game creator have since been removed.[citation needed] These three level groups do not differ from each other, apart from having different names, though each consecutive level increases in difficulty. Levels consist of finding either a password (known as a "UN/PW" by the game's community) or finding a URL to use in order to proceed to the next level. Passwords do not require a player to create an account but instead are given to a player once they have found the answer to a level's riddle. Each level answer or solution is unique, often requiring specific skills such as decoding ciphers, image editing, musical knowledge, and formerly remote viewing.
