Open-source browser games you can wrap in ads and ship. Every one is MIT, Apache, BSD, CC0 or Unlicense, was loaded as an iPhone and tapped in a headless browser, and keeps its author's copyright line. Tap a cabinet to watch the self-test clip.
Play them all in the arcade → (installable on your phone, new games at 07:00 and 19:00)
Licence: only MIT, Apache-2.0, BSD, CC0, Unlicense (and MIT-0/0BSD). GPL, AGPL, LGPL, MPL, CC-BY-SA, CC-NC and repos with no licence are dropped. READMEs are scanned for separate non-commercial asset licences.
Mobile (0–10): starts from static signals (viewport meta, touch handlers, responsive canvas, download size) and is then corrected by the self-test: Chrome as an iPhone at 390×844, ten taps and a swipe, with every input handler counted. Overflowing pages, JS errors and slow loads lose points.
Quality (0–10): stars, forks, push recency and issue close-rate. "Thin signal" means under 25 stars and almost no issues.
Self-test pass: the page rendered something and the picture changed while being tapped. Games with no live URL are mirrored, unmodified and with their licence file, to matalon888.github.io/game-library.
