Getting started
Do I need to install anything? No. Use a modern browser on 67game.store.
Is it free? Yes.
Which mode should I pick first? Webcam if camera+light are fine; otherwise keyboard 6/7. Guide: how to play.
Camera & tracking
Why is the game waiting for hands? Lighting, distance, palms not facing camera, or permission issues. Work the setup lab.
Why are reps missing? Amplitude too small/large, hands leaving frame, motion blur, or dropped inference FPS. Engine detail: MediaPipe notes.
Does my video get uploaded for tracking? Gameplay hand tracking is designed to run on-device. Read Privacy Policy.
Scoring & modes
Why is my score low with decent reps? Combo multipliers depend on sustained RPS bands—see scoring.
Can I compare keyboard and webcam scores? Not as the same event—read mode comparison.
Training & safety
How do I improve? Follow the 7-day plan with short quality sessions.
My wrists hurt. Stop. Review wrist care. This is not medical advice.
Kids & community
Can children play? With guardian judgment on camera, duration, and callsigns. Family notes live in the wrist/safety guide.
How do leaderboards stay fair? See fair play.

Performance & devices
The page feels laggy. Close other tabs, especially video calls. Prefer AC power on laptops. Try Chrome/Edge. If the skeleton stutters, switch to keyboard for that session.
Mobile play? Possible on many phones, but heat and framing are harder. Landscape with the phone propped stable helps. Watch for hands leaving the short frame edge.
Does offline work? After assets load once, some caching may help, but first visit needs network to fetch scripts and the hand model. Leaderboard submit needs network.
Accounts, data, ads
Why might I see ads in the future? Independent hosting and development cost time and money. If ads appear, they will follow Google policies and should not block the core play button with deceptive layouts. Policy pages stay available regardless.
Can I delete my score? Contact us with the callsign and approximate time. We will help when feasible.
