Ivory Rush

Notes fall down four lanes and you tap them in time. The chart is built from the music itself: while a track plays, this page listens to it and asks the RULES for a note whenever it hears one. With no music library it plays a metronome instead — the same engine, the same scoring, a tempo you can hear.

Tap the lane a tile is in as it crosses the line. A / S / D / F or 1 / 2 / 3 / 4 also work. A stray tap costs nothing; a note that slides past untapped breaks your combo.
