What to play first
Try Reaction Timer or Aim Trainer if you want a short reflex build. Try Memory Match, Tile Slide, or Color Flood if you want a puzzle. Try Upgrade Clicker if you want a little prototype progress loop you can come back to later.

Free retro browser games from the archive
Octarine Online is a curated archive of small browser games that start fast and make sense immediately. The current shelf is made of Early Recovered Builds: simple prototype-like games restored for quick play, score chasing, and the old one-more-round itch.
Some builds are reflex tests, some are puzzles, some are word or math games, and some are compact progress loops. They save simple progress or best scores in your browser when it makes sense. No account is required, and the archive is built to stay easy to use on desktop or mobile.
What is coming next
The Unfinished Kingdom is the next flagship project: a mobile-first browser idle RPG hidden inside Cabinet 14. Nullspace Arena remains available as a restored retro space-combat cartridge while the larger kingdom moves toward public Alpha.
