"HTML" is no protocol at all. I assume you talk about "HTTP".

If you can set up your own services on the server side you can also use
web sockets as most current browsers support them (see
<http://caniuse.com/#search=web%20sockets>).

A very simple "quick & dirty" example:

<https://arnowelzel.de/tools/chat>

The backend is a web socket server based on Ratchet and stunnel to
handle the TLS stuff. But newer web servers like nginx can also be used
as a web socket proxy - or Apache 2.4 using the mod_proxy_wstunnel module.

Ajax with polling every x seconds may be a good fallback in case the
browser does not support web sockets.

Yes - at least there needs to be a list of "active games" with the
connected players on the server.
