Osu!

**osu!** is a free, open-source singleplayer and multiplayer rhythm game.

## Background

*osu!'*s first version release dates back to September 16th, 2007. *osu!* heavily relies on community made charts called "beatmaps". Over the years, osu! has grown into a household name among rhythm game fans and has a dedicated fanbase. There are multiple different ways to customize your experience in the game. As an example, you can change the look of notes, layout, and much more via changing skins.

The ranking system in osu! is different compared to most rhythm games. After playing a beatmap you can get "Performance Points", abbreviated as "pp". How you acquire pp for a play is determined by the difficulty of the map and how well you played it (accuracy, combo, misses etc.). pp given can range from almost nothing, to hundreds depending on the player and the map itself.
On your profile, all your plays and their pp are collated in your "Best Performances", where your highest PP scores (known as "top plays") are displayed. Your total pp is calculated with the weighted sum of all your plays in order of the highest to lowest pp, where the weighting is

0.95
n

{\displaystyle 0.95^n}

 where

n

{\displaystyle n}

 is the placement of that play in order from highest to lowest.

## Other Game Modes

*The main osu! is commonly referred to as **osu!standard**.*

### osu!taiko

osu!taiko is a game mode based on the popular game series Taiko no Tatsujin. Its gameplay is an emulation, but its quality is obviously lower than the original game. What's special about this game mode, is you can hook up official Taiko no Tatsujin controllers.

### osu!catch

osu!catch is the least popular out of all the game modes. You move left and right with its repective arrow keys in order to catch the fruits. You can "dash", which increases your speed, by pressing the Shift key.

### osu!mania

osu!mania is by far the most popular out of the optional game modes. You can play up to 12K (12 keys at once). However, most mania players don't play up to 12K and just play 4K or 7K.

## Ways to Play

As mentioned previously, osu! is known for having multiple ways to play. Lots of different play styles have been popularized in the community. The two most popular though are mouse and tablet players. But, you can still play using just about anything, including other game controllers or random objects to aim. A small portion of players even play using a touchscreen.

### Mouse

Mouse is the most accessible option, but most osu! players find playing with mouse more inconvenient due to "mouse drift". However, there still is a part of the community who is very dedicated to using mouse as a preferred style. Most players usually use the mouse as a moving tool and use keyboard to tap the notes.

### Tablet

Tablet is by far the most common and popular among competitive players. Many of the big players in the community use tablet as their preferred play style. These tablets are typically drawing tablets that can be found online.
