How to Play 67 Challenge
TEST YOUR HAND SPEED AGAINST THE WORLD IN 20 SECONDS
01
ALLOW CAMERA
Grant camera permission when prompted. Your camera stays on-device — nothing is recorded or uploaded.
02
SHOW BOTH HANDS
Hold both hands in front of the front camera. Keep your background still and face a light source for best detection.
03
WAVE AS FAST AS YOU CAN
Move your hand back and forth rapidly. Each detected wave counts as one rep. Standard mode is 20 seconds — unlock 40s & 60s with VIP.
04
HIT 67
The legendary target is 67 waves in 20 seconds. Most people average 30–40. Can you reach the number?
05

⚡ PRO TIPS

- › Keep your arm relaxed to avoid fatigue
- › A still background helps the camera detect motion accurately
- › Good lighting = better detection
- › Practice makes perfect — each attempt refines your technique
