This client requires JavaScript and WebAssembly.

- The same API the board on the project page uses. A game started here is visible there and vice versa.
- First load
- About 10 MB of WebAssembly, downloaded once; later visits revalidate it with a conditional request and reuse the cached copy until the client is rebuilt.

- A modern browser with JavaScript and WebAssembly. WebGL2 draws the terminal when available; otherwise xterm.js falls back to its slower DOM renderer.
