About 67 Challenge

The 67 Challenge is a hand-wave speed game that asks one simple question: how many times can you wave both hands in 20 seconds?

The concept is deceptively simple. Open the app, face the front camera, and wave both hands as fast as you can. Every clean wave rep is counted live using on-device AI hand detection (powered by MediaPipe). At the end, you see your score and find out if you have what it takes to reach Legendary status at 67 reps.

The number 67 is the threshold. Hit it and you're in an elite group. Most people score between 20 and 45. Getting past 60 takes real practice. Getting past 67 takes obsession.

Built for speed, simplicity, and sharing

No elaborate setup. No tutorial. No lives or tokens. You open the app and you play. The score is immediately shareable — a card gets generated so you can post your result to TikTok, Instagram, or send it to friends. The viral loop is the score itself.

Privacy first

All hand detection runs entirely on-device. No video, images, or camera data are ever sent to our servers. Your camera stays private — nothing is recorded or uploaded. The app only stores your score, name, and country for the leaderboard. See the Privacy Policy for full details.
