Getting a high score in the 67 Challenge isn’t just about moving your hands fast. Technique, setup, and environment all matter — sometimes more than raw speed. Here are seven things that will immediately improve your score.
1. Use your wrists, not your whole arm
This is the single biggest technique mistake beginners make. Waving from the shoulder is slow and exhausting. Instead, keep your elbows relatively still and drive the motion from your wrists. Wrist-led waves are smaller, faster, and use less energy. You can sustain them for the full 20 seconds without fatigue.
Practice by resting your elbows on a table and waving. If your elbows are lifting, you’re doing it wrong.
2. Get your lighting right
The AI hand detection model works by finding hand landmarks in the camera image. In poor lighting — or with bright light behind you (backlight) — the model struggles to lock on and your waves go uncounted.
Best setup: Face a window or a lamp. Natural daylight from the front is ideal. Avoid playing with your back to a window or in a dim room.
3. Keep both hands visible at all times
The game requires both hands to be detected simultaneously. If one hand drifts out of frame, you lose detection and the rep doesn’t count. New players often let one hand drift wide while focusing on the other.
Practice keeping your hands close together, roughly shoulder-width apart, centered on the camera view.
4. Find the right distance from the camera
Too close: your hands fill the whole frame and move in/out of detection range constantly. Too far: the model can’t resolve the hand landmarks accurately.
The sweet spot is roughly 30–50 cm from the phone. This gives the AI enough image detail while still giving your hands room to move in and out.
5. Prop your phone up
If you’re holding the phone with one hand while waving only one hand, you’re leaving points on the table. Propping the phone against a wall, pillow, or phone stand so it holds itself frees both hands and almost always results in a noticeably higher score.
6. Warm up your wrists before you play
Cold or stiff wrists move slower. Before a serious attempt, do 30 seconds of gentle wrist circles and shakes. You’ll notice the difference in the first 5 seconds of the game.
7. Control your breathing
It sounds minor, but tensing up and holding your breath limits your hand speed. Breathe normally throughout the 20 seconds. Relax your shoulders. The more relaxed your upper body is, the faster your wrists can move.
The fastest improvement: combine tips 1 and 2
If you only apply two tips, make it wrist-led motion plus good front lighting. These two changes alone can take a player from Solid (30–49) to Elite (50–66) in a session or two of deliberate practice.
The Legendary threshold (67 reps in 20 seconds) works out to roughly 3.35 waves per second — sustained. That’s fast, but achievable with the right technique. Most players who reach it say the breakthrough came from switching to wrist-led movement and ensuring good lighting for the hand detection.
