* In this game you use arrow keys to blow bubbles when they appear in the holes.
* Bubbles appear according to rhythm of the music (bpm)
* Groups of bubbles may contain from 1 to 3 bubbles of various colors. In each bubble there is a different arrow.
* Each arrow key on the keyboard is assigned to a particular bubble color and arrow direction. However, the layout may change dynamically in the hardest modes of game such as Skill Mode and Survival.
* The purpose of the game is to get a higher score. If more bubble groups in a row are blown without any mistakes, you get a larger "Combo" multiplier for your score.
* "Time Match" is a simplified mode where you are allowed to make unlimited number of mistakes within the given time.
