I've never played this "Ouendan" thing - what is it?

Osu! Tatakae! Ouendan is a rhythm game for the Nintendo DS. The gameplay consists of only three elements: tapping circles on the touchscreen, dragging a ball across a fixed path and rotating a spinner very fast. All these elements are timed to (covers of) popular Japanese songs. It looks like this on the DS:


You can see the circles on the bottom screen, and on the top screen you have the story. Each stage is basically a self-contained story about a person in trouble. That's where the Ouendan (Cheer squad) comes in. Through the magical power of male cheer-leading, you have to help the people in trouble.

How do I play?

Full explanation: osu! Standard

While most PC users won't have a touchscreen at their disposal, this game is made to be playable with a normal mouse, as well as any number of input devices you can possibly think of. Different play styles can be found in the Play Styles page. There are some songs which push the limits of the normal mouse (and you), but all the (ranked and approved) beatmaps have been tested and (most can be) passable using only a mouse.

Game-play Basics

Tutorial: (Bundled with PC osu!) Original tutorial, Ranked beatmap version

The game-play put emphasis on your:

  • Adaptability and reaction to stimuli (that is, the hit-able objects appearing all over the screen at lightning speed).
  • Understanding of the song beat and design.
  • Your control of your mouse (or your fingers/pen-poking skills if you are using a tablet instead).
  • Timing of your hits on the object that appeared on the screen.
  • Ability to spin the mouse (or your finger/pen for tablet) in circles.
  • Your physical stamina (especially marathon songs).
  • Proper mouse positioning and hand-eye coordination.
  • Your hardware capability (especially your mouse/tablet).

These are some of the vital skills you will learn as you progress your journey on becoming an osu! rhythm master. Before you set out to become a rhythm master, you must learn the basics (and theories) of the hit-able objects.

Let's learn about what the hit-able objects are, shall we?


Main article: Hit circle


  • Here you can see the circles you have to tap.
    • The smaller coloured circle on the outside shrinks and you have to hit the note at the exact point the outside circle overlaps with the white border.
  • To understand the hidden charm of hit-circles, you should not only rely on your perception (your eyes) but also the understanding of the beatmaps' beats and rhythm by your ears (auditory).


Main article: Sliders


  • Here we have a slider.
    • First, you have to hit it at the right moment, but it doesn't end there.
    • A ball will start to move across the path you see.
    • You have to hold the mouse/keyboard-button (or your finger/pen on the tablet) and keep your pointer inside the thick orange circle surrounding the ball as it moves.
      • You cannot control the movement, and you must follow its movement.
      • The orange circle will appear if you are holding it and disappears when you leave it.
    • Sometimes, as in the screenshot above, you have to move back at the end of the path.
    • You can tell by the reverse symbol at the end of the path.


Main article: Spinner


  • This is a spinner.
    • You have to click then hold the hit-button, and the mouse is used to spin (clockwise or counter-clockwise) in circles like mad before the time (which is, that blue circle line) runs out.
      • The bars on the outside indicate how close you are to passing.
      • The small bar below the spinner shows spins per minute, means the number of spins you are making if you continue that speed of spinning for one minute.
      • If you didn't hold any hit-button prior to spinning, you will not fill up the gauge at all.
  • On the DS, this is a good way to scratch your touchscreen (or screen protectors), especially on the higher difficulties.
  • In osu!, spinners have been toned down as to not be such a nuisance to complete.
    • The maximum number of spins per minute achievable is 477 which is also the rate at which the Auto game modifier spins while the Spun Out game modifier spins slower at 287 spins per minute.
    • Learn and try to spin in very small circles (like the Auto does but it will put a strain in your arm if you are not used to it.)
  • [Mouse]If your cursor did not spin at all but moving statically despite you are spinning really fast, either understand the limit of your mouse or get a better mouse/mousepad.
    • Conventional mouse may suffer this issue, and it is best to start spinning slowly instead of suddenly spinning really fast so that the mouse can detect what you are doing.

In-Game Interface


This is the osu! game style interface.

  • The top left bar is your "health".
    • This will decrease at a steady rate [depending on the beatmap difficulty set by the mapper(s)], but you can replenish it by hitting notes at the right time.
    • A perfectly timed hit (300 hit or Geki Beat) will increase your health more than a badly timed hit (50 hit).
    • A total miss will take a good chunk out of your health.
  • Next to the health bar (at the right) is your score.
  • Below the score is your accuracy.
  • The circle beside your accuracy and below your score is a timer bar, which shows the song length.
  • The number on the bottom left is the combo counter/score multiplier.

Alternative Game Modes

What is "Taiko"?

Full explanation: Taiko
Taiko gameplay.

Taiko no Tatsujin is a Taiko Drum rhythm game made by Namco, that involves the simulation of playing the drums to the beat of the music. In osu!, beatmaps can be played in the styling of Taiko no Tatsujin through the use of special Taiko game mode.

Like basic osu!, there are three elements of gameplay.

Basic explanation


  • This will appear as either a red or a pale-blue circle. They are named as red (Don) notes and blue (Katu) notes.
    • If it is a small red note, you must press the button bound to the inner portion of the Taiko drum or hit the large flat area (center) of the TaTaCon.
    • If it is a small blue note, you must press the button bound to the outer ring of the Taiko drum or hit the sides of the TaTaCon.
    • If the note is a LARGE circle, you should press or hit both of either inner or outer drum depending on the colour of the note for additional points.
      • The notes must be pressed or hit when they reach the small white circle next to the drum below the status bar on the play-field.

Hit balloons

  • They are deciphered as normal small red notes but with a inflatable balloon behind it.
    • You should hit the inner drum continuously until the hit counter reaches zero.
    • You gain points for each hit and bonus points for popping the balloon.

Drum rolls

  • Drum rolls appears as yellow bar in the play-field.
    • You should hit the inner (or outer) drum continuously until it is done.
      • For LARGE note, you should hit both buttons on the inner (or outer) drum simultaneously and continuously until it is done.
    • You gain points for each successful hits.
    • You can choose to ignore it at the cost of your possible points gained from the drum roll.


  • These appear as spinners, with a countdown displaying the time you have remaining to clear it.
    • You must hit the inner and outer drum in order (like red,red, blue,blue, red,red, and so on) until the Denden meter is full.
    • Bonus points are given for extra hits after completing the Denden.


The default controls for the Taiko mod are:

Red: [Mouse] Left click, [Keyboard] [X] or [C], [TaTaCon] Flat surface of the drum.
Blue: [Mouse] Right click, [Keyboard] [Z] or [V], [TaTaCon] Outer surface of the drum.
osu! cursor placement does not matter when playing.

You may configure the keyboard buttons as you see fit, from the Input tab in the Options menu.

What is "Catch the Beat"?

Catch the Beat gameplay.
Full explanation: Catch the Beat
  • Catch the Beat is the second special game mode to be added in, after Taiko game mode.
  • Instead of clicking circles, you are now tasked to move the catcher at the bottom of the screen while the fruits fall from above.

Controlling the catcher

If the Relax mod is used, control of the catcher is done by moving the mouse instead.
  • By default, the left [<-] and right [->] arrow keys are used to move the catcher.
  • Pressing the left [SHIFT] key with one of the arrow keys will make the catcher dash in that direction at x1.5 speed (indicated by a bright glow at the catcher).

What is "osu!mania"?

osu!mania (7K) gameplay.
Full explanation: osu!mania
  • osu!mania is the third special game mode to be added in, after Taiko and CtB game mode.
  • This mode has been widely used in almost all of the major rhythm games that require good hand/leg coordination, where the beat notes with their quantity depending on BPM and difficulty move on the conveyer, and the player have to press the correct key for that specific beat note in time. Though the game mode was originally made as an imitation of Beatmania style of playing, however, by changing the number of keys, you can make it look more like Guitar Hero (5) or Dance Dance Revolution (4) and so on. Currently, you can set from 4 to 8 Key.


[Symmetrical]Key Bind colour and placement by number of buttons (outdated)
Default Key layouts of osu!mania (Options->Input)

There two different binding-styles, Symmetrical and Left to Right.

  • Symmetrical style mimics the button placement of DJMAX, in which the center key is "spacebar", in which, created a feeling of "stepping" the pedal similar to the arcade version. Centre key matches the middle column (5K and 7K only) and the other column matches the keys in its corresponding place.
  • Left to Right style mimics the button placement of Beatmania IIDX, where the first column matches to the key1, then the second column matches the key2 and so on.

Symmetrical key binding (For DJMAX style)

  • For left hand buttons — (K1)A, (K2)S, (K3)D, (K4)F
  • For right hand buttons — (K6)J, (K7)K, (K8)L, (K9)semicolon ";".
  • Center button — (K5)spacebar. [On 5K and 7K only]
  • The Special button — left SHIFT and left control "Ctrl".

Left to Right key binding (For Beatmania IIDX style)

  • From down to up then down to up again: (K1)Z, (K2)S, (K3)X, (K4)D, (K5)C, (K6)F, (K7)V, (K8)G, (K9)B [K9 is not used]
  • The Special button — left SHIFT and left control "Ctrl".
Key Symmetrical binding
4K K3, K4 - K6, K7
5K K3, K4 K5 K6, K7
6K K2, K3, K4 - K6, K7, K8
7K K2, K3, K4 K5 K6, K7, K8
8K K1, K2, K3, K4 - K6, K7, K8, K9
Key Left-To-Right binding
4K K1, K2 - K4, K5
5K K1, K2, K3, K4, K5
6K K1, K2, K3, K4, K5, K6
7K K1, K2, K3, K4, K5, K6, K7
8K K1, K2, K3, K4, K5, K6, K7, K8

    • Offline play even when your account is logged in is not counted.
  • Grades given for your profile depends on beatmap difficulties, not as whole.
    • If the beatmap has 3 difficulties, and you SS all three of them, you will receive 3 SS and not just one SS in your profile.

Common issues and questions

Where can I find and get the beatmaps?

Detailed explanation of the beatmaps: Beatmaps

You can find it from the main page under the name "Beatmaps".

  • Just remember to log in to your osu! account before-hand or the server treats you as a guest and prohibit you from downloading beatmaps from the site.

Can I disable Kiai Time?

No, because unlike video, they are integrated to the game (as a part with the hit objects), thus cannot be disabled.

The maps are too hard! Where can I find some easier maps?

Pokebis has compiled a set of beatmaps suitable for beginners to play. You can find them here: http://osu.ppy.sh/forum/t/5456

Also, the ranked beatmap version of osu! tutorial is good for practicing some of the possible mapping design you will come across. It's an excellent training map for newbies and experienced players.

Alternatively, you can sort the ranked beatmap list by difficulty. The easiest maps are at the top of the list.

What does Level in my profile actually do?

Absolutely nothing. There is no difference in any way when comparing a Level 100 player against a Level 1 player except the player's own skills and experience of play. There is no handicap for the lower level nor there is an advantage for the higher level (except personal experience and hardware used).

Level is based on your total score accumulated when online with your account whether you pass or fail the beatmap. Formula given here

Why is my profile stats different ingame?

Keep in mind that osu! has four game modes so you might be looking at the wrong game mode.

Manually select the game mode at your profile that you want to view.

Profile Mode Buttons.gif

Why am I seeing random white lines on screen every time I play?

Make sure that the smoke/skywriting key binding is not the same as the keybinding you use at playing.

Why do I not have the max possible combo when I have no misses?

You released a slider too early or you barely clicked the hit-circle. Answer's Source
