Hurtle

Browser games fail on school and office networks for dull reasons: the domain sits in a blocked category, the address carries an obvious keyword, or the page itself arrives while the ads, fonts and trackers it pulls from elsewhere never do. Hurtle answers the last case by being one file that loads nothing from anyone else, with no ads, no sign-in, no cookie banner and no sound.

What is inside is an original endless descent rather than a Slope port or clone, and the site says so plainly while linking to where the real Slope lives. You steer a single ball down a narrowing track, dodging blocks and clearing gaps while the floor keeps tilting under you. Ten sliders cover steepness, path width, obstacle density, jumps, floor tilt, speed, camera height and angle, and the neon and accent colours. The track seed changes once per UTC day, so the whole world runs the same course on the same date, with no account and no netcode behind it.
