'osu!' is a free-to-play rhythm game that is played by clicking on beatmap elements, such as circles, sliders, and spinners, in time with the music. The game allows importing of an infinite number of local songs, with a built-in system for applying beat and shape elements (in numerous difficulties) for unrestricted puzzle gameplay. In addition to registered online play, the game also allows users to play in a free Guest mode that only allows access to local songs. Its main dashboard promotes easy access to the Play, Edit, and Options screens.

The user interface of osu! is simple and intuitive, enabling quick discovery of available songs. Lists are separated into five separate categories – Performance, Spotlights, Score, Country, and Multiplayer. This large community has led to the creation of official ranking lists that feature players from all around the world. Today, after several years on the market, osu! has managed to attract over 20 million registered players who enjoy music rhythm puzzles at all hours of the day. Gamers must also track the visual representation of beats and melodies with their mouse, and even draw trajectories of varying complexities, which can make mastering some songs a truly challenging experience.

However, the game does not promote only precise timings but also skilled aiming skills.

Same as in the original console game, the PC version of osu! gives players chance to interact with attractive songs by appropriately reacting to on-screen prompts that can be activated with timely mouse button presses. With a large library of pre-installed songs and the ability to import custom music, fans of the rhythm video game genre can lose themselves in music, enhance their skills, and experience their favorite songs like never before. Osu! is a popular music rhythm game that mimics the gameplay functionality of the “ Osu! Tatakae! Ouendan” game from the Nintendo DS portable console, enabling Windows PC users to experience thrilling musical puzzle game experience directly on their monitors.
