- Tap the glowing tile itself while its lower edge is inside the cyan HIT RANGE. You can also swipe through several short tiles.
- Follow the recording. PERFECT is within 160 ms of the beat, GREAT is within 320 ms, and GOOD is within 540 ms.
- Slide long ribbons upward. Start on the bright head and move at least one short thumb stroke toward the arrows. A tap alone does not finish a ribbon.
- Build a combo. Every hit adds one. At 24, FEVER starts and doubles points until the next miss.
- Recover from misses. A miss breaks the combo and lowers the performance bar. Ten consecutive misses end the run.
- Keyboard lanes run left to right: D, F, J, K. Arrow keys use Left, Down, Up, Right in the same order.
If the picture and sound feel apart on your device, use Timing offset in Settings. Fall speed changes only how early tiles appear.
