There are various types of key patterns, depending of the game, which are from 3-Key, up to 8-Key (depending of the game), and also three basic difficulty levels called easy, normal and hard.

There is a special difficulty level called "SC" (Super Crazy) for certain songs. In almost every version, as notes are played with perfect rhythmic accuracy, a "fever gauge" will be charged. When it is fully charged, "Fever" can be activated to multiply the combo, varying between x2 and x5 or more depending on the accuracy of each note pressed. Players can play by themselves in Training Mode, or challenge with other online players through the Battle Mode. In addition, players can customize their avatars, game skins, note symbols by unlocking them.

Avatars, gears and notes have their unique stat modifiers, like DefUP, AUTO, and others.
