For grown-ups
Each game is a single self-contained index.html: no build step, no analytics, and no network calls beyond its own voice clips — except that chess loads its rules engine (chess.js) from jsDelivr and Sight Words its font from Google Fonts. Speech is pre-rendered clips of a neural English voice (German for chess), with the browser's Web Speech API only as the fallback, and it always waits for a tap first. Progress is kept in localStorage on the device — nothing is collected anywhere.
The games are written for an iPad mini in either orientation, with finger-sized targets, and they respect prefers-reduced-motion.
The start page at jackbenn.ing is built from google814/Jack, which is the source of truth. The repos here are copies kept in step by tools/sync-game-repos.sh in that repo, so each game also has its own page and its own link.
