Tap every black tile before it scrolls off the top.
Goal: Tap every black tile before it scrolls past the top of the board.
Tiles rise up through four columns. Tap anywhere inside a tile's column — the topmost un-tapped tile in that column clears with a musical note.
Game over: let a tile reach the top without being tapped, or tap a column that has no tile.
Speed climbs every 10 taps. Four modes set the starting tempo — Easy, Normal, Hard, Extreme. Best score is saved per mode on this device.
