I cannot find any 'resign' button when only two players are left. It can be obvious who the winner is going to be. I would find it useful to be able to resign and move to the next game.
The initial post says
1. resign when only two players remain in the game.
You could also add a 'Resign' button at any stage of the game which would would take us to the other thread http://smgstudio.freshdesk.com/support/discussions/topics/11000030971?page=1
