http://en.wikipedia.org/wiki/NetHackPlayers over the years have compiled extensive documentation for every aspect of the game, from instructions on exactly how to navigate certain obstacles, to detailed formulas explaining the probability of in-game events. Gleaning spoiler information from the source code is known as source-diving. The documents are collectively known as spoilers.
Opinions vary on the use of spoilers. NetHack is widely considered one of the hardest games of all time, due to its intentional lack of a facility to reload a saved game after making a mistake. Even with complete access to all spoilers, the game still poses a considerable challenge. Many people have played for years without ascending. Some consult spoilers extensively during the game, others only consult common information, and others choose not to read spoilers and will learn as they play.
(Ascending = Amulet of Yendor vinden en mee naar boven nemen.)
Pas op! Spoiler warning!
Lees het onderstaande of lees het niet; je moet het helemaal zelf weten...The cockatrice: a typical example of a complex NetHack monster. Its touch can turn the player to stone, so attacking it using the player's bare hands is not recommended. Its corpse can be wielded by a gloved character (or monster), whose attacks then carry the cockatrice's stoning ability. Furthermore, if the player's character is female, and is polymorphed into a cockatrice, the player can lay cockatrice eggs—which have several interesting applications. The cockatrice is an example of a monster or item that inspires the compilation of spoiler files.
The floating eye: a monster without any active form of attack, this is one of the most dangerous creatures to the inexperienced or incautious NetHack player. If the player attacks a floating eye when not blind and not capable of reflecting its gaze, there is a very high chance of it immobilizing the player for many turns, leaving him or her open to attacks from other creatures that roam the Dungeons of Doom. The most embarrassing player deaths (such as being killed by a newt or grid bug) are often the result of an encounter with a floating eye. Eating a floating eye's corpse, however, will grant telepathy, allowing a blinded player-character to see all creatures with brains that are on the same level.
The soldier ant: even though this creature has no unusual abilities, it often comes as a surprise for unprepared players. These critters move in swarms, are very fast, hard to hit and hit hard themselves. On the alt.org public NetHack server, they are the most common cause of death for players. It is something of a tradition in the #nethack IRC channel on the freenode server to say, "Go Team Ant!" when Rodney (a bot) announces that an alt.org player's character has been killed by an ant.
The nymph: taking its origin in Greek mythology, these creatures are females of astounding charm. They manage to entice men and women alike into entranced helplessness, stealing the belongings of an adventurer who has fallen into their hands and teleporting away.
The mind flayer: this creature (and its more powerful relative, the master mind flayer) is very dangerous in close combat, as it can extract and eat parts of its opponent's brain. Not only does this cause an eventually-fatal loss of intelligence, but it can also cause its victim to forget information such as the layout of previously explored areas or the nature of any items being carried. As another example of "the DevTeam thinks of everything", a mind flayer is at a significant disadvantage when fighting creatures without a head.
Gremlins: these creatures multiply when they have contact with water, as in the movie Gremlins.
Quantum Mechanics: these characters are another humorous addition by the NetHack DevTeam. While not dangerous on their own, quantum mechanics' attacks teleport a player randomly within the same level unless the player has the ability to control teleportation. Quantum mechanics occasionally carry a box; if so, the box always contains Schrödinger's cat. Whether the cat is alive or dead is not defined until the box is opened.
The xorn is perhaps one of the most unusual and useful characters. It can go through any door and nearly any wall, and can exist in solid areas. A xorn will not drown in water because it does not breathe. It also has a very damaging multiple hit attack, can wield a weapon and has good strength. Because the xorn can eat metal, a player polymorphed into a xorn can consume metal items, such as magical rings and amulets. In this way, the player can acquire the special powers conferred by wearing the item. For example, a player who polymorphs into a xorn and eats a ring of invisibility may become permanently invisible, even after changing back into human form.

Oew. Wat een fantastisch spel is het toch...
