At last there is a way to play Mah-Jong online with others using British rules…† . The reason is that this new game app, Mahjong Friends Online, “lets you play any style of Mahjong with your friends”.
† …and a way to get some relief from the constraints that Covid has put on our game
MFO (below) = Mahjong Friends Online
I’ve been using the app since the beginning of the year now and (although I must confess to only playing by BMJA rules), this seems to me to be a reasonable claim.
