Step back into frame
The model needs to see both shoulders and both wrists at the same time. If you stand too close, your hands fly out the top of the frame on every rep and the counter freezes.
20 seconds. Your camera. Your reps. Climb the leaderboard.
Works on desktop & most phones. Best results in good light.
Tap start. Your browser asks for camera access. Frames stay on your device.
Stand far enough that both shoulders are in frame. Drop your arms.
A 3-second countdown then go. Lift wrists above shoulders, drop, repeat.
Result drops at the buzzer. Submit a name, take the leaderboard.
The 67 speed game is a free, browser-based arm speed test built around the viral 6-7 hand-motion trend. The rules are simple: raise your arms above your shoulders, drop them below, repeat as fast as you possibly can. A pose-detection model running locally in SixSevencounts every full repetition and gives you your 67 score on the global leaderboard.
The 67 speed run lasts exactly 20 seconds. There is nothing to download, no account to make, and no payment screen. Open the page, allow camera access, and play. Your video never leaves the device — every frame of computer vision happens client-side, in real time.
Anyone with a webcam and 30 seconds. Streamers use SixSeven as a quick on-stream challenge with their chat. Friends use it as a party game. Fitness fans use the 67 speed test as a 20-second warm-up sprint that gives a number at the end. Kids who saw the 6-7 trend on short-form video use it to settle whose arms are actually faster.
The page loads a small pose-estimation neural network straight to your device. Every video frame, the model locates 33 body landmarks — including both shoulders and both wrists. A rep is registered when both wrists travel from below your shoulder line up above it and back down, with smoothing and a minimum interval so ordinary hand jitter does not get counted. The result is your 67 score.
Within the limits of camera-based pose tracking, very. Good lighting, contrasting clothing, and standing far enough back that your full upper body fits in frame are the three biggest factors. If your wrists drop out of view or your shoulders are clipped at the edge of the frame, the counter pauses until it can see you again — so the 67 leaderboard stays clean.
Small adjustments to camera setup and motion form can add 20–30% to your final number. These are the ones that make the biggest difference.

A bright lamp pointing at you (and not directly into the camera) makes pose tracking dramatically more reliable. Backlight from a window is the worst case.
Dark long sleeves on a light wall, or a light shirt on a dark wall — the higher the contrast between you and your background, the cleaner the keypoints.
The detector is tuned to ignore small jitters. Half-reps where your wrists barely cross the shoulder line do not count. Bigger swings score more, even if they feel slower.
A consistent 1-2-1-2 tempo will out-score 5 seconds of frantic flailing followed by a recovery break. The tempo is your throttle.
Built-in laptop cameras drop frames under load. If you have a USB webcam, plug it in. Close other tabs while you play.
The 67 speed game is a free, browser-based arm speed test built on the viral 6-7 hand-motion trend. You raise your arms above your shoulders and drop them as fast as you can for 20 seconds. A pose model running on your device counts every full rep, gives you your 67 score, and ranks you on the global 67 leaderboard.
Open SixSeven in a modern browser, allow camera access, position yourself so both shoulders are in frame, and tap start. There is no install, no signup, and no payment screen — every play is unlimited and free.
Your browser loads a small pose-estimation neural network on the fly. Every video frame, the model finds 33 body landmarks including both shoulders and both wrists. A rep is registered when both wrists travel from below your shoulder line up above it and back down — with smoothing and a minimum interval so jitter does not double-count.
No. The 67 speed challenge runs entirely in your browser. There is no app, no signup, and no extension. Just open the page and play.
Nowhere. Pose detection runs entirely in your browser using on-device computer vision. Only the final score and the rep timeline are sent to our server when you submit a leaderboard entry. Video and images never leave your device.
Your 67 score is the number of full arm reps the counter validates during the 20-second window. A rep is one full down-to-up-to-down cycle of both wrists relative to the shoulder line. Half-reps and micro-jitter do not count.
The world record on the SixSeven leaderboard updates live. Top players hit several hundred reps in 20 seconds. Submissions are signed server-side and validated against a plausibility cap, so only honest scores reach the leaderboard.
No. Each session is signed with a server-issued token. The server validates the rep timeline, monotonic timestamps, and a per-challenge maximum reps-per-second. Implausibly fast, out-of-order, or empty timelines are rejected automatically.
Yes. iOS Safari and Android Chrome both support pose tracking with the front camera. Prop the phone up so your whole upper body is in the frame for best results.
The lite pose model is fast on most hardware, but cheap webcams and older laptops can drop frames. Close other tabs, move into bright light, and try a wired webcam if you have one.
Bigger arm range and consistent rhythm beat random flailing. The detector ignores micro-jitter, so half-reps do not count — full down-to-up motion is what scores.
Not yet. The whole challenge is built around real-time pose tracking. We may add motion-free modes in the future.
Yes — completely. There is no paywall, no premium tier, no ads asking for payment. Play and submit to the leaderboard as many times as you want.
