As LFAW said, once the round limit expires (trench or no trench), the winner is the player with the most troops.
However, if two or more players are tied for most troops, then player with the most regions will win.
If two or more players are tied for most troops AND most regions, red wins (unless red has been eliminated, in which case green wins).
High score: 2200 - July 20, 2015
Game 13890915 - in which I helped clinch the NC4 title for LHDD
