67 Hand Game 🙌

A computer vision clicker game inspired by the viral 67 trend. Use your webcam and your actual hands to play — raise and lower them to earn points, build combos, and unlock upgrades.

Built with Python, OpenCV, and MediaPipe.

How to Play

Stand in front of your webcam and raise your hand above the green line, then lower it below the red line. That's one rep — one 67.

Keep going without stopping to build a combo multiplier:

Combo	Multiplier
5+	x1.5
15+	x2.0
30+	x3.0
50+	x5.0

Spend your 67s on upgrades using keys 1–5. Let your 67s grow even while you rest.
