Rhythm Tap

🕹️ How to play

1. How to start: Tap the big drum to start; it counts 3 · 2 · 1 · Go. Beginner (80 BPM) is selected by default, or pick Standard or Challenge above the drum first.
2. Listen, then tap it back: Each round opens with a demo bar: the sweep line passes solid dots and you hear a clap on each one — just listen. Then comes the tap bar: the metronome keeps going and you tap the drum on the same spots, marked by hollow rings.
3. Read your timing: Every tap instantly shows a verdict like "Early 42ms · Good", and your hit is drawn left of the target when early and right when late. After six rounds you get a 0–100 score, a rank, your average offset, how steady you were and one tip.

📖 Rules & variants

A game is 6 rounds; each round is a demo bar followed by a tap bar with the metronome running throughout. Round 1 is four quarter notes, round 2 adds rests, rounds 3–4 add eighth notes and rounds 5–6 are syncopated. Beginner is 80 BPM, Standard 100 and Challenge 120 — on Challenge the targets are hidden while you tap, so you play from memory.

Judging: each target has a ±120ms window. Within 35ms is Perfect (100 points), within 75ms Good (70), within 120ms OK (40). No tap in the window is a Miss, and two or more taps in one window is Mashing; both score 0.

Stray taps and combo: a tap belongs to whichever target beat it is near, not to the caption on screen — within 120ms of a target it is judged for that beat (so tapping the first beat a touch early still counts even while the caption says “Listen”). A tap during the tap bar that lands outside every window is a stray. It costs no points but resets your combo; taps anywhere else (the middle of the demo bar, the count-in) are ignored. Combo is only a stat — it never multiplies your score, so one slip only costs that one beat.

Score = the average of all target points, rounded. 90+ is Human Metronome, 75–89 Locked In, 60–74 Getting There, 40–59 Now and Then, under 40 Lost the Beat. Each difficulty keeps its own best.

Latency calibration: Bluetooth headphones and some devices delay the sound. Tap 8 beats at 60 BPM and the median offset is applied automatically (−200 to +400ms). If your taps are too uneven or out of range it refuses and tells you why. If a game shows you consistently late or early, one button folds that offset into calibration for the next game.

Same-chart challenge: after a game, 2–6 people can pass the phone and play the exact same six bars. Ranking is by score, then hits, then the smallest average offset; challengers' results don't overwrite the device's personal best.
