osu! is a rhythm game primarily developed, published and created by Dean "peppy" Herbert. Originally released for Microsoft Windows on September 16, 2007, the game has also been ported to macOS, Linux, Android and iOS. Its gameplay is similar to titles including Osu! Tatakae! Ouendan, Taiko no Tatsujin, Beatmania IIDX,[3] Elite Beat Agents, O2Jam, StepMania, and DJMax. osu! has an active esports community, and is also sometimes recommended by professional players of other games to practice or warm up.[4][5]

Game Modes

There are four official game modes: "osu!" (unofficially called osu!standard), "osu!taiko", "osu!catch" (formerly "osu!ctb"), and "osu!mania".[6][7] A level in any of these modes is called a "beatmap". In osu!standard, beatmaps consist of three items – hit circles, sliders, and spinners. These items are collectively known as "hit objects", and are arranged in different positions on the screen and in different points of time. Taiko beatmaps have drumbeats and spinners. Catch beatmaps have fruits and spinners, which are arranged in a horizontal manner. Mania beatmaps consist of keys (depicted as a small bar) and holds. The beatmap is then played with accompanying music, simulating a sense of rhythm as the player interacts with the objects to the beat of the music.[8][9] Each beatmap is accompanied by a background. The game can be played using various peripherals, but the most common setup is a graphics tablet or computer mouse to control cursor movement, paired with a keyboard.[10][3]

All game modes also have certain mods which can be applied which alter the gameplay in some way. While each mode has its own unique mods, most are standard between game modes. These mods can be divided up into three categories: Difficulty increase (Hard Rock, Sudden Death/Perfect, Hidden/Fade In, Double Time/Nightcore, Flashlight), Difficulty decrease (Easy, Half Time, No-Fail, Spun Out) and Unranked (Auto-Pilot, Relax, Cinema, Auto, ScoreV2). The Difficulty increase and Difficulty decrease mods raise and lower the score multiplier, respectively.

osu!standard

osu!standard, usually referred to as just "osu!", is the most common game mode and involves clicking circles, holding sliders, and rotating spinners. 0, 50, 100, and 300 points are respectively assigned for each hit (excluding spinners) based on how accurate the hit is. Inspiration for this mode was taken from Osu! Tatakae! Ouendan and Elite Beat Agents for the DS.

osu!taiko

osu!taiko is a game mode which consists of clicking red or blue notes respectively called Don and Katu to the beat on a drum-like interface, inspired by the Taiko no Tatsujin series.[11]

osu!catch

osu!catch, formerly known as osu!CtB (Catch the Beat), is a game mode which consists of catching falling fruit to the beat by controlling a mini-character holding a plate.[12]

The player moves the character to the left and right using their arrow keys. The player can dash at 2x speed by holding shift. There are several types of fruits that have different effects.

osu!mania

osu!mania is a game mode which consists of a piano-like style of clicking notes to the beat, similar to the Beatmania IIDX series. The number of keys ranges from 1 to 9 (2 to 18 with the use of dual stages), with 4 keys and 7 keys being more popular among players.[13]

Beatmaps

osu! has five different beatmap categories:[14]

  • "Ranked & Approved" – community-made beatmaps that are approved to be playable by Beatmap Nominators, or BNs. These maps give performance points (pp) that allow players to rise in the global player rankings. Ranked maps always feature a global top 50 leaderboard. Approved was formerly made to not give score, which used to be the ranking system before ppv1 was introduced.
  • "Qualified" – beatmaps which are on their way to becoming ranked. Beatmaps will remain in "Qualified" for 1 week, after which they will be ranked. Beatmaps in "Qualified" will be disqualified and have the beatmap status reset to "Pending" if any issues that do not pertain to osu!'s ranking criteria are found. Qualified beatmaps give performance points, although in the past they did not.
  • "Loved" – beatmaps that have received a significant reception from the community and were approved to be playable. They only feature a beatmap leaderboard. This leaderboard can be reset by the beatmap author. Loved beatmaps do not award performance points.
  • "Pending" and "WIP" – beatmaps which are either not fully done or waiting to be ranked. They do not have a leaderboard and do not award performance points.
  • "Graveyard" – Pending and WIP beatmaps which have not received an update in over 28 days. Just like pending beatmaps, they do not have a leaderboard and do not award performance points.
  • "Not submitted" – beatmaps that are still in development and haven't been submitted to the osu! website for ranking status. Beatmaps like these will only be accessible to people that have the .osz file (osu! beatmap file).

osu!supporter

The game offers a buyable service called osu!supporter, which grants many quality-of-life features to the user. Players are able to download beatmaps directly from inside the game, without the lengthy process of using browsers through a service called osu!direct. A heart icon beside the username on the official osu! website, additional pending beatmap slots, faster download speeds, access to multiplayer on cutting edge builds, friend and country-specific leaderboards, one free username change, more in-game customization, a yellow username in the in-game chat, and more customization on one's user page (the "me" tab).[15] osu!supporter does not affect the ranking system, or provide any in game advantage. osu!supporter is not a reoccurring service, and you'll need to buy it manually again when it runs out.

osu!lazer

The osu!lazer song selection screen

osu!lazer[16] is a free and open-source remake of the original game client under heavy development. it was originally projected for the stable version to come out in 2017, however as of 2020 not all features are currently working.

It introduces a new graphics framework[17] that adds improved visuals, performance and more flexibility for future changes. This new framework that powers osu!lazer will allow users to create their own game modes which can then be played and modified in the osu!lazer client.[18][19]

The development of osu!lazer started in 2015 and development versions of osu!lazer are currently available for testing on Microsoft Windows, macOS, Linux, Android, and iOS. osu!lazer is written entirely in .NET Core.

Music from osu!'s "featured artists" are selected by the community as being suitable for play, and for having a compatible copyright status.[20] As of October 2020 there are over 100 featured artists. Some featured artists have created tracks specifically for use in osu!, and some artists are also known for making music for other rhythm games, such as Camellia (Masaya Oya [es]) and Cranky (Hiroshi Watanabe) who are known for their works in Konami's Sound Voltex and Beatmania IIDX series of games.[citation needed]

Reception

Jeuxvideo.com reviewed osu! favorably with 18/20 points in 2015.[21] In 2010, MMOGames.com reviewer Daniel Ball said that while the game was very similar to Elite Beat Agents, it was differentiated by its community's large library of high-quality community made content and customization.[22]

osu! has been used and recommended by esports players such as Ninja and EFFECT, as a way to warm-up and practice their aim.[5][8]

Community and competitive play

An audience watches two top players ("idke" and "RyuK") compete at the osu! TwitchCon Booth in 2018

As of November 2020, osu! has 15,210,892 players worldwide.[citation needed]

osu! contains three main facets of competition between players. In multiplayer lobbies, up to 16 users play a map simultaneously. On individual maps, players compete for highscores on global leaderboards or against highscores set by themselves and friends. Players also compete with their ranks, which are calculated by accumulating "performance points" (pp). pp is based on a map's difficulty and the player's accuracy.[23] According to PC Gamer, most competitive osu! players score between 100pp and 400pp on a map, with few ever exceeding 500pp. In July 2019, a player, Vaxei, exceeded 1,000pp for the first time, followed by another player, idke, less than twenty-four hours later.[4][24]

Since 2011, there have been eight annual "osu! World Cups" (usually abbreviated as "owc"), one for each game mode (osu!mania having two for 4 key and 7 key). Teams for World Cups are country-based, with up to eight players per team.[25] There are also many different community-hosted tournaments, differing in rank range, types of maps played, and how the teams are composed.[26] Winners of tournaments typically receive prizes such as cash, merchandise, profile badges and/or osu!supporter subscriptions.

osu! also features different events, such as fanart and beatmapping contests. Unofficial events and conventions are also being held. The biggest unofficial event held in the community is "cavoe's osu! event"[27] (usually referred to as "osu! event" or "COE"), held at The Brabanthallen[28] in 's Hertogenbosch, The Netherlands. The event has been arranged three times since 2017 yearly. However, due to the COVID-19 pandemic, COE 2020 was cancelled.

Mobile clients

iOS

In 2011, osu!stream was released as an adaptation of osu! for iOS devices running iOS 6 and later, also developed by Dean Herbert. The main difference between osu! and osu!stream is that osu!stream beatmaps are not user-created and are instead made by the developers of osu!stream. The version also includes some new gameplay elements.[29] On 26 February 2020, Herbert announced that he released the source code and plans to halt development of the game, releasing one final update that made all the levels free to download.[30]

It is possible to play the beta of osu!lazer on iOS via TestFlight.[31]

Android

It is possible to play the beta of osu!lazer on Android devices using an APK.[citation needed]
