After js13k: a next project with no 13KB cap

js13k just wrapped with a record year. If you shipped something under 13KB and still have browser-game energy, here’s a next project that drops the size constraint and keeps the open-source loop.

TrainGames is an Apache-2.0 collection of commute-friendly browser board, card, word, and dice games. Many are meant to keep working offline after the first load.

The builder loop is simple:

Pick a game spec
Build your own implementation (vanilla, React, Phaser, AI-assisted — all fine)
Deploy it
Contribute it back

Multiple implementations of the same game are welcome. That’s the point.

Current snapshot:

25 live games
51 prompt concepts
28 still awaiting a first deployment

Two weekend-sized starters still have no first version:

Boggle-style: https://github.com/davidlifschitz/online-board-games/issues/7
Love-Letter-style: https://github.com/davidlifschitz/online-board-games/issues/8

Play: https://os-online-board-games.vercel.app/play.html
Build: https://os-online-board-games.vercel.app/build.html
Repo: https://github.com/davidlifschitz/online-board-games

If you just came off js13k, this is a good place to reuse that shipping muscle without the zip limit.
