The player's leader party member runs from right to left across a scrolling background that differs depending on the song chosen. Notes fly by the player's cursor and the player must tap the touchscreen as the notes line up with the cursor. Missing a note and taking damage results in the party leader being replaced with the next party member in line, cycling back to the leader after all four party members have been passed. Higher chains and hitting criticals on notes result in the characters running faster, allowing them to progress through more of the stage. How fast a character moves also varies depending on their Agility.
