''Think about a real or fictional character. I will try to guess who it is.''

[[http://en.akinator.com/ Akinator]] is an online Twenty Questions game where you challenge the eponymous genie, Akinator, to guess a character or real-world person you've picked.

It is noted for having a very extensive database of characters and people from even the most niche and obscure works--this is because the database is being constructed by the players; not only they can introduce new characters to Akinator, but he also learns more about the characters as more questions about them are answered.

As a result, it is typical to see "Akinator threads" on various forums which are mostly filled with people being [[{{HSQ}} amazed]] at how ably Akinator can "read their mind".

!!I think of... these tropes:

* ArtificialStupidity: Akinator cannot recognize identical/opposite questions, so sometimes he asks you for your character's gender two or three times. It can be FridgeBrilliance at times--some characters, particularly {{AFGNCAAP}}s, can be both female and male, or neither, or crossdressing or transgender. Of course, he'll ask if they have black hair and then ask if they have blond hair, plus the always entertaining "Asks if they're from one universe, is told yes, guesses a different universe". This is likely the only program to think ''Franchise/MassEffect'' and ''{{Halo}}'' are the same universe. And sometimes it will ask you if you've met/said hello to the character ''after'' you've confirmed it's a fictional character or dead historical figure. Apparently it believes you might be ''Literature/ThursdayNext'' or a time traveler.
* TheAssimilator: A variant of this, where you can increase the knowledge of Akinator by submitting characters he couldn't guess. You can send in questions too, so he can have more ways of narrowing down his options.
* BatDeduction: Sometimes appears to exhibit this, in cases where he asks a lot of seemingly (but not genuinely) pointless questions and then jumps to the correct answer.
* BecomingTheGenie: This is supposedly what will happen to you if you try to cheat by giving wrong answers.
* CurbstompBattle: Sometimes, he may end up guessing your character in a few questions.
* TheDevTeamThinksOfEverything:
** Well, not the dev team actually, but the contributors/players. Akinator can guess such "characters" as "Someone who kept clicking on No to see what happens," as well as "A smart guy who presses 'Yes' (that would be you)." Likewise, saying the 'Probably/Partially' answer will get you 'Probably Someone', Don't Know leads to 'The One About Whom Nothing Is Known', and 'Probably Not/Not Really' will lead to 'Someone who Doubts their Own Doubt'. He can even guess what he calls "Something I Can't Talk About" -- whose accompanying picture is a man staring, fascinated, down his boxer shorts, as well as "I wasn't actually thinking of anyone." Worse yet, Akinator himself is included, to the point where he'll ask [[OhCrap "Do you think I'm too stupid to guess who it is?"]] And if if you were thinking of his mother, a picture of a model in a genie suit appears. If you are listed as young and the answer generated is a wild guess he gives you "I know the answer, but I don't think it's for children." If you try to get it to guess something that's not a character, he will say something like "Something I don't know because it's not a character".
** Not only is Akinator included, but so is everything in his room, including the gold decorations on the pedestal, ''Akinator's mustache'', and the sphinx-like statue nearby.
* ExcusePlot: The "Story of Akinator".
* FissionMailed: Sometimes he only guesses the wrong character because he tries to guess too quickly. Click "Yes" to continue, and the second time he guesses, he'll usually be right. (For example, answering questions in a certain way may cause him to guess "Urdnot Wrex" from the Mass Effect series. If you were thinking of "Urdnot Grunt" instead, who superficially has a lot of similar characteristics but isn't as famous and therefore wouldn't spring to mind as quickly, rest assured that he'll answer "Grunt" the second time he tries to venture a guess after you've given him more information.) There's always a 90% chance he'll guess correctly after four or five tries.
* GenieInABottle: Akinator, though he doesn't grant wishes.
* GracefulLoser: Akinator is this when he failed to guess your character. ("Bravo! You have defeated me." And he applauds you too, even if it feels somewhat half-hearted.)
* HiveMind: Akinator's "intelligence" is the result of the gazillion users' contributions.
* JustOneMoreLevel: The website was supposedly created to satisfy Akinator's perpetual addiction to 20 Questions. From the other side of the screen, people can spend quite a bit of time finding a character obscure enough to stump him.
* MoodSwinger: Akinator can switch from raging mad to smugly satisfied with a single question.
* ObfuscatingStupidity: Sometimes Akinator will ask a logical series of questions leading to your character, then suddenly start asking random unrelated questions, apparently having been thrown off the scent. In the end though, he gets the character right. He figured out what your character was early on, and was just using the remaining questions (and you) to learn more about the character in question.
* OneOfUs: He knows about Trope-Tan.
* RougeAnglesOfSatin: Some of the characters' names are poorly spelled. Thankfully they can be fixed.
* SmallNameBigEgo: He'll often start to get a little narcissistic ("Is your character handsome?") if you're using him.
* TakeThat:
** Unpopular people, such as UsefulNotes/GeorgeWBush or [[CtrlAltDel Tim Buckley]], generally are associated with questions like "Is your character stupid?"
** "The maker of this site" is represented by a literal jackass.
* VictoryPose: You're going to be seeing it A LOT.
* YouGottaHaveBlueHair: If you try to make him guess an anime character, you're likely to get a chain of questions like "Does your character have blue hair? Does your character have green hair? Does your character have purple hair? [[OverlyLongGag Does your character have pink hair? Does your character have...]]"
