5
6	''osu!'' is a {{freeware\|Game}} {{rhythm game}} made by Dean "peppy" Herbert, based on the gameplay of the ''[[VideoGame/OsuTatakaeOuendan Ouendan]]'' and ''VideoGame/EliteBeatAgents'' [[VideoGame/InisDSRhythmGames series]] of games for the [[Platform/NintendoDS DS]].
7
8	Game levels, called beatmaps, are created and submitted by users via a LevelEditor. These can later be refined through community modding if the creator requests it and gets [[OfficialFanSubmittedContent ultimately approved]] by members of the Nomination Assessment Team and the Beatmap Nominators.
9
10	Ranked beatmaps give Performance Points (or [[FunWithAcronyms pp]], for short) after being beat, [[DoubleEntendre giving more pp]] the better you did in the map, and they also get a scoreboard featuring the best scores done in it. The beatmaps also give experience points based on how you much you scored in them, [[CosmeticAward but the levels do nothing and are ultimately cosmetic]].
11
12	Besides the ''Ouendan/EBA'' gameplay, ''osu!'' includes three additional game modes: one based on the ''VideoGame/TaikoNoTatsujin'' series, one based around the gameplay of ''[[VideoGame/{{beatmania}} beatmania IIDX]]'' or ''VideoGame/{{O2jam}}'', and one based around the gameplay of ''VideoGame/EZ2DJ''[='=]s [=EZ2Catch=] mode (where one tries to catch falling fruit).
13
14	Apart from Solo mode, players can [[CompetitiveMultiplayer compete]] in all four modes in online multiplayer matches in rooms which can contain up to sixteen players, in single or team battles, in order to get the highest score, accuracy or combo possible, [[CoopMultiplayer or play beatmaps together by taking turns between combos]], depending on the room settings. In osu!mania, two players can play locally using the same keyboard.
15
16	It has an UpdatedReRelease codenamed ''lazer'', which will be released as an update to the stable client. It is rebuilt from ground up using [[https://github.com/ppy/osu-framework a new framework]] that improves visuals, performance, and flexibility for future changes. It also has a new UI design and new quality-of-life features not present in the stable client. It is currently under heavy development and available for Windows, Platform/MacOS, Linux, Android, and iOS.
17
18	Its website can be found [[https://osu.ppy.sh/ here]], the stable client can be downloaded [[http://osu.ppy.sh/p/download here]], and ''lazer'' can be found and downloaded [[https://github.com/ppy/osu here]].

24	----
25	!!This game provides examples of:
26	* AllLowercaseLetters: The game is called ''osu!'', not ''Osu!'' or ''OSU!''
27	* {{Anime Theme Song}}s: Around 1/3 of all the ranked maps are these.
28	* AprilFoolsDay: The jokes each year revolve around changes in the game's genre ("Touhosu", a Franchise/TouhouProject/osu! hybrid), gameplay ("osu!core", where the songs in every beatmap had their pitch and speed increased), staff (unexpected demotions or promotions), and beatmaps (pretending to approve and praise an extremely poorly made beatmap).
29	** Also, some of those jokes have ascended. osu!core became a permanent available mod called Nightcore, and Touhosu! has been confirmed as in development by peppy.
30	* CallAHitPointASmeerp: The currency of this game is called "kudosu", and is earned through modding unranked maps.
31	* CrossOver: The beatmap for Music/{{Queen}}'s [[http://osu.ppy.sh/s/5381 Don't Stop Me Now]] is based on the plot of a FanFic which combines [[Franchise/AceAttorney Phoenix Wright]] with ''VideoGame/EliteBeatAgents''. It's as awesome as it sounds.
32	* {{Determinator}}: A player can become this if they're trying to pass, get an FC (Full Combo), or enter the Top 50 on a beatmap, especially if the beatmap is pretty difficult. If they lose a rank in the top 50, don't expect them to quit playing for hours until they beat the player who beat their score.
33	* EasierThanEasy: Some maps like [[https://osu.ppy.sh/beatmapsets/325158#osu/741477 this]] like to add difficulties that aren't even 1 star.
34	* FakeDifficulty:
35	** On mapping side, it's HEAVILY discouraged nowadays, and maps with it have a very low chance of being ranked. Using solely tricks like low (or high) Approach Rate, high HP drain, etc., are no longer acceptable in the Ranked Beatmaps section. In addition, some very specific mapping techniques are not allowed to be ranked due to being very confusing and frustrating for players. A list of these can be found [[https://osu.ppy.sh/wiki/en/Mapping_techniques/Unrankable here]].
36	** There was a time when maps could be [[https://osu.ppy.sh/s/132 impossible to S-rank,]] [[UnwinnableByDesign even by Auto.]]
37	** Or have FAKE SPINNERS in the [[https://osu.ppy.sh/s/3959 storyboard.]]
38	** Playing for score? Aside from the combo multipliers practically encouraging restarting over one mistake (a game design element shared with ''osu!'''s source game), modifiers add to your score, most notoriously the modifier that increases the song's speed by 50% to give a 12% score boost. So to get high-ranking scores you have to alter the song.
39	* FunWithAcronyms: GMT (Global Moderator Team), NAT (Nomination Assessment Team).
40	** Also, some teams that don't exist anymore, like the QAT (Quality Assurance Team), MAT (Modding Assistance Team), and BAT (Beatmap Appreciation Team).
41	* GameWithinAGame: Taiko, Catch The Beat, and osu!mania modes.
42	* GradeInflation: As in Ouendan and EBA, S comes after A, but a perfect performance in osu! earns the player an SS rank. An SS achieved under the Hidden and/or Flashlight mods has a separate sprite (alternate colouration in the official skin) and commonly referred to as "SSH".
43	* IdiosyncraticDifficultyLevels: Beatmappers can name the difficulties of a beatmap set into whatever they like. However, NonIndicativeDifficulty names on a beatmap set's lower difficulties render it unrankable.
44	* HarderThanHard: Many beatmaps have an Insane difficulty, and some even have a difficulty above Insane (officially named "Expert").
45	** "Oni" and "Inner Oni" respectively for Taiko beatmaps.
46	* InterfaceScrew: The Hidden and Flashlight mods. Hidden makes it so that incoming circles disappear before having to be clicked on, and Flashlight darkens the area around your cursor so you can't see incoming circles clearly.
47	* LevelEditor
48	* LettingTheAirOutOfTheBand: Occurs on a failure. There's a grinding sound, and the music track slows down as it stops playing. Any visual beats also collapse and fade as well.
49	* {{Mascot}}: [[https://osu.ppy.sh/wiki/en/Mascots#pippi pippi.]]
50	** [[https://osu.ppy.sh/wiki/en/Mascots#yuzu Yuzu]] for osu!catch.
51	** [[https://osu.ppy.sh/wiki/en/Mascots#mani-&-mari Mani & Mari]] for osu!mania.
52	** [[https://osu.ppy.sh/wiki/en/Mascots#mocha Mocha]] for osu!taiko.
53	* MarathonLevel: There are a handful of "marathon" beatmaps, commonly ranging between 10-15 minutes in length, with some even longer:
54	** [[http://osu.ppy.sh/s/972 paraparaMAX I]], at 36:17.
55	** Music/WithinTemptation's entire album ''[[http://osu.ppy.sh/s/29157 The Unforgiving]]'' in one beatmap, the current record holder at 52:57.
56	** In addition, there are several unranked maps that pass the 100 minutes mark, also some of them are over Insanely difficult!
57	* NonIndicativeName:
58	** The Double Time modifier multiplies the speed of the song by 1.5x.
59	** The Half Time modifier multiplies the speed of the song by 0.75x.
60	* NoPlotNoProblem: Just click the circles to the beat.
61	* OneHitPointWonder:
62	* Sudden Death and Perfect modifiers fail a run whenever the player, respectively, misses a note or scores less than a perfect, which is a convenience for players who are going for a (perfect) full combo run.
63	** Sometimes, the HP drain on certain maps are so high that even missing one circle or note is guaranteed to throw you off and cause you to fail.
64	* PinballScoring: In standard mode, the maximum possible score of very long beatmaps with huge note counts can grow to very large numbers. In one extreme example, the very long "[[https://osu.ppy.sh/s/29157 Within Temptation - The Unforgiving]] described in MarathonLevel above has 10-digit scores in the top four ranks (as of this edit). To get good scores in any given map, getting a full combo is crucial. "Scorev2" modifier (typically used in tournaments) caps them to 1,000,000 points, averting this trope.
65	* PowerCreep: To a certain extent. The players are getting better, of course, but there are also more and more maps that can be "farmed" to earn PP. At the end of 2014, the highest PP score was 558. At the end of 2015, it was 667. In the first month of 2016, there have already been five scores that have been higher than that.
66	* RageQuit: A common practice to avoid submitting and saving low accuracy scores, though that doesn't work anymore.
67	* RhythmGame: The entire premise of the game.
68	* RidiculouslyDifficultRoute: On osu!taiko, turning on the ''Hidden'' and ''Flashlight'' mods makes '''all''' of the notes unable to be seen, making the player play the ''entire'' map '''from memory'''. There's a reason you only really see this combination being used in only 1-2* maps.
69	* ScoringPoints: There are two scoring systems: the "[=PointValue=] x ([[ScoreMultiplier combo]] + [=ConstantA=]) x ([=ConstantB)=]" system used in the source games, and the "pp" system (which gives a score according to how impressive the play was). There are also scoring systems that are exclusive for multiplayer matches, such as accuracy (percent-based system, which is the average accuracy for each note, being a 300 a 100%, a 100 a 33.33%, a 50 a 16.66% and a MISS a 0%), and Combo (the player with the biggest combo the moment when the map ends wins). In a multiplayer match, you can choose which system to use for ranking.
70	* SelfImposedChallenge: Using one or more of the difficulty increasing mods and/or going for SS (100% accuracy) runs. [[invoked]]
71	* StylisticSuck: [[http://osu.ppy.sh/s/23058 NotShinta's cover]] of Music/ImogenHeap's [[https://osu.ppy.sh/b/36067&m=0 Aha!]] is awful. Yet so very good. Notable for being the beatmap with the lowest user rating on the site.
72	** The Jarto series is based on this trope, having an... odd narrative told through Stylistic Suck storyboards.
73	** Spinsmith also has his series of bad song covers.
74	** [[https://osu.ppy.sh/s/21145 ztrout]] is like Aha?, except it came first.
75	* SuperDeformed: Miniature versions of [[{{Mascot}} pippi]], [[VideoGame/OsuTatakaeOuendan Ryuuta]], and [[VideoGame/EliteBeatAgents J]] could be found on the homepage and Catch The Beat, but were later removed.
76	* UnwinnableJokeGame: Several maps, such as [[https://osu.ppy.sh/beatmapsets/150945 "Centipede" (Knife Party)]] and [[https://osu.ppy.sh/beatmapsets/791900 Aleph-0]], are designed to look impressive while sacrificing playability (to the point of being unplayable without Auto in some cases) and thus unrankable.
77	* VideoGamePerversityPotential: Thanks to the versatile beatmapping and skin customization features, you can make the game display anything you want, though the really inappropriate beatmaps/skins cannot be shared on the official site.
