I think the more major variants (suicide, crazyhouse, bughouse) are on the to-do list, but for more minor ones there just isn't enough demand. But you can play all variants manually in this group.
knightmate chess
People that want to play less common variants like Knightmate live on-line, are of course welcome to use my Internet Chess Server for this. Amongst the supported variants there are:
Knightmate
Spartan Chess
Shatranj
Courier Chess
Seirawan Chess
Gothic Chess
Capablanca Chess
Grand Chess
Great Shatranj
WinBoard or XBoard can be used as graphical interface for all of these games; just select "Use Internet Chess Server" at startup. The IP address of my server is 80.100.28.169 .
As these variants are not in great demand, you should not expect to find anyone on the server that you could challenge, and you would have to bring your own opponent, or play by appointment.
Knightmate chess could be considered as one variant here in chess.com.site? F
