Scoring and levels
Points in Hand Ninja come from the code-defined rewards of 5, 10, 15, 20 and 25 points and more for different actions, so the bigger moves are worth chasing. Perfectly timed or perfectly placed moves earn bonus points in Hand Ninja. Every 700 points you reach a new level, and Hand Ninja speeds up and sends more at you each time. You start with 3 lives. Your best score is saved in your browser, and signed-in players also appear on the Hand Ninja leaderboard. Watch out for boss waves, which take several hits but pay out big points.
Tips and strategy
- Stay near the centre in Hand Ninja; it gives you the most room to dodge in either direction.
- Don't chase every pickup in Hand Ninja — grab only the ones on your safe path.
- Good, even lighting from the front makes tracking in Hand Ninja far more reliable than a bright window behind you.
- Replay Hand Ninja a few times: each run teaches you the patterns, and scores usually double after the first five games.
Device requirements and privacy
Hand Ninja needs a device with a front or web camera (any recent Android phone, iPhone, laptop or Chromebook) and works best in Chrome, Edge or Safari. Allow camera access when asked; hand tracking runs entirely on your device with Google MediaPipe, and no video ever leaves it. It is free to play; free players may see a short ad between rounds (never during play), and Premium removes all ads.
