Permit. Pinch. Post.

Before you start

You need three things:

• A camera — front-facing on a phone, or a webcam on a desktop.
• One free hand — held about an arm's length from the camera.
• Decent light — daylight or normal indoor light is fine. A backlit silhouette is not.

The game does not need an account, a download, or a sign-in. If you can load this page, you can play.

Step 1 — Allow camera access

When you tap START on the splash screen, the browser asks for permission to use your camera. Tap Allow. The game cannot run without this — there is no fallback tap mode, because the entire point is that the camera measures real physical hand speed.

If you tapped block by accident, you can reset camera permission for the site through your browser's site settings, then reload the page.

Step 2 — Get in frame

Hold your playing hand up so the camera can see it clearly. Some quick rules:

• Frame your hand so the whole hand is in the picture — palm and all five fingers.
• Roughly the distance from your face that you'd hold a phone to read it works well.
• Keep the background simple. Cluttered backgrounds with other hand-shaped objects can confuse the tracker.
• Don't wear a glove. The tracker reads your real fingers.

You will see a 3-2-1 countdown after start. Use that time to settle your hand into a comfortable position.

Step 3 — Pinch fast

The mechanic is simple: touch your thumb-tip to your index-fingertip, then open them back up. That cycle — open → close → open — is one pinch.

What makes a pinch count:

• The fingers have to actually come close together. A half-pinch in mid-air won't register.
• Then they have to come back open. Pinching and holding doesn't add reps.
• Speed beats range. Small, sharp pinches usually score higher than big dramatic ones.

Find a rhythm. Most strong scores come from a short, controlled motion repeated as fast as your fingers can recover.

Step 4 — Watch the clock

You get 20 seconds. A timer ticks down on screen. Your live score updates as the camera detects pinches. When the timer hits zero, the count freezes — that is your final score for the run.

There is no time bonus, no combo multiplier, no streak meter. Twenty seconds, raw pinches, done.

Step 5 — Save your score

After the game ends, the result screen shows your score, your tier, and the live leaderboard. You'll see your row highlighted, with the people above and below you for context.

To save your name on the board, tap the editable name field on your row. Type a name (up to 20 characters). Press Enter or tap the checkmark. Your row updates immediately and your name is saved locally so the next time you play, the field is already filled.

If you don't enter a name, you'll show up as Anonymous. The score still counts.

Troubleshooting

Camera permission didn't work

If you blocked the camera and want to undo it: tap the lock or info icon in your browser's address bar, find Camera, set it to Allow for this site, and reload the page.

The tracker isn't seeing my pinches

Three common fixes:

• Light: move toward a window or turn on a lamp. The tracker needs to actually see your fingers.
• Distance: too close and your hand fills the frame; too far and the fingers are tiny. About arm's length is usually right.
• Background: try a plain wall behind your hand. Avoid busy or moving backgrounds.

It feels laggy

Close other tabs and other apps that use the camera (video calls, other browser tabs). The tracker runs in your browser and shares whatever CPU is available.

I want to play again

Tap Run It Back on the result screen. The countdown runs again, the camera stays on, and you go straight into another 20-second round.
