Group Gomoku: the sign up sheet board game (up to 200+ players)
So, Group Gomoku is pretty much Gomoku - connect five (exactly) but with sign in sheets to track who moved where and what move needs to be played next. I could go on and on about the hidden gambling mechanics, the importance of the swap2 rules from a balancing perspective, ect. And I will :D (eventually). I hope this game brightens up a fridge near you.
