There's fairly little to tell about Scware's invention. Mid-november 2012 Benedikt Rosenau had notified me about the application of the Symple move protocol to Hex, leading to Symple Hex. It occured to me that there wasn't a square connection game using the move protocol, so I made one. I thank Luis Bolaños Mures for pointing out the possibility of an impasse, leading to a shorter and more generic phrasing of the restriction rule.
