A game for any webpage

Page
Parkour

Tilt any webpage back and watch it rise into a 3D world, floating high above the clouds. Paragraphs stand up as buildings, headings become towers, and the gaps between them turn into streets. Then run across it all as a ninja, with samurai guards on your tail.

Every block on a page keeps its exact place. It only gains height, so the city you land in is the page you were reading, laid out the same way. Headings stand tallest, images make sturdy towers, and boxes and cards become plinths that their content stands on.

Hills under a starry night sky

How to move

RUN
W A S D runs where the camera looks. Shift sprints, arms streaming back like a proper ninja.
JUMP
Space jumps. Press it again in mid-air for a somersault that reaches the taller headings.
WALL RUN
Keep running into a wall (or press Space) to run straight up it. Jump and press Space again along a wall to run along it. Space again kicks off.
GLIDE
Hold Space while falling to spread your cloak. From a tall tower you can glide across half a page.
LOOK
Click once and the mouse looks around, or use the arrow keys. Scroll to zoom, V switches between three-quarter, side-on and overhead.
GUARDS
Samurai patrol the page. If one spots you it gives chase. Lose it in the seams, or land on its head.
SMOKE BOMB
Press F to vanish in a cloud of smoke. Whoever was chasing you loses track and searches the cloud instead.
STARS
Gold stars hide on rooftops, down in the seams and up in the air. Collect them all against the clock.

Things to try on this page

A throwing star

Climb the big title at the top of this page: run straight at it and press Space, and you'll run up its wall and onto the roof. From up there, hold Space and glide down onto the cards. The picture next to this paragraph is a tower too, and the gap between it and this text is a seam you can climb by kicking from wall to wall.

Play it on any site

Chrome extension (works everywhere)

⬇ Download the extension (.zip)

  1. Unzip the download.
  2. Open chrome://extensions and turn on Developer mode (top right).
  3. Click Load unpacked and choose the unzipped page-parkour folder.
  4. Pin it, then click the icon or press Alt+Shift+P on any page. Do it again to quit.

This also works in Edge, Brave and Arc. Chrome only installs extensions from outside its store this way, so expect it to remind you that a developer-mode extension is enabled.

Bookmarklet (no install)

Drag this button to your bookmarks bar. Then, on any page, click it to play and click it again to quit.

🥷 Page Parkour

A few sites with strict security settings (GitHub and X, for example) block bookmarklets. Use the extension there.
