OSU is the most played game, and it consists of playing beatmap by clicking circles, holding sliders, and rotating spinners. The game is performed with a mouse and a keyboard or touch screen. The following are simple steps to learning how to play OSU.
Click on the huge OSU circle, and this circle is in the middle of the screen. Click on the play button, which is the first option on the menu. Scroll to a song you want to play and click on it, then click on OSU. Click on the circles, and when a ring closes around the circle, click on it, which will count as a hit.
Move the sliders and drag your cursor to stay within the slider circle or ball. Spin the spinners, and when the spinner appears, click your mouse, and move it in circles as fast as possible. The faster you spin, the more extra points you will attain.
