new game sneak peak: Amoebas

I just started a thread for it in the main games thread but am curious, Mr. SD, how are the groups cleared? Is it something about having x many of the same guys linked together or is it more about making a solid space of certain dimensions? I thought at first it was as simple as having three of the same guys touching one another but looking tat the video there are some cases where there already are three of the same guys connected and they didn't get vanished.

 

Ahh, thanks. So the key to big points is to find out ways to make a group well over just the 7+?
