osu! is primarily played using a mouse to click 'beats' displayed on-screen in time with the music. This is analogous to tapping the beats on the Nintendo DS screen with a stylus. At the top of the screen, a health bar is present, which is constantly drained. If the player hits or clears a beat, the health meter at the top of the screen fills slightly. If he misses a beat, a large part of the meter is drained, and if it gets completely empty, he fails the song. There are three types of beats in the game: Hit circles, sliders and spinners. Every time the player hits a hit circle or an end circle, touch a slider tick, or clear a spinner, the combo is raised by 1. If he misses any of the above, the combo is reset back to 0.
