UVS.
A browser-based trading card game sandbox, built around the UniVersus ruleset. The long-term plan: an external deck builder, deck files you can bring to any browser, and a card engine driven entirely by JSON — so new games are just new card data, not a rewrite.
This page is the multiplayer lobby: one player creates a game and gets a PIN, the other enters that PIN, and the two browsers connect directly (peer-to-peer, no server in the middle). Right now the PIN connection is verified working end to end, but it doesn't drive a live match yet — that's next. In the meantime, the actual board and rules are playable locally, hot-seat style.
