Hello all,
You can play live Makruk on Playok:
http://www.playok.com/fr/makruk/

and live Chu Shogi (also Dai Shogi) here:
http://sdin.jp/en/browser/board/chushogi/

I've not found any website for Janggi liveplay. But there is turn-based Janggi at chessvariants.org and Dualpose.

Hello all, and first of all my best wishes for this new year,

I'm searching for people who would be interested to play some online live games of some chess variants which are not implemented here like:

-Chu Shogi
-Janggi
-Makruk

If you're interested, please contact me.

Regards.
