What students work through

  • Packets
  • IP & DNS
  • Routing & TCP
  • HTTPS & the web

Every scene in Relay follows the same pattern: a plain sentence saying what the idea is, a working model the student controls, a real example, then a “your turn” step.

The free preview opens the first 3 scenes in your browser. The full course comes with your college’s TwiddleLabs subscription: teachers use it in the browser, and students get it in the TwiddleLabs app on their phone and laptop, working offline.
