Confession: I had to uninstall the app from my iphone because it was eating up too much of my time.<p>This game has a lot of interesting things to balance - defend my territory vs. expand into new, deciding when to grab territory boldly and when to be conservative, deciding whether another player is vulnerable to be cut off vs. the risk you put yourself into by trying to cut them off.<p>There's complexity that emerges from a simple ruleset that's more interesting than you'd think.<p>Also: watching other players to deduce their strategy, skill level,and understanding of the game.<p>I'm surprised that more players don't expand diagonally, which seems to me to be strategically strong.<p>I also like how the game requires different things as your territory grows: early stages are about survival, middle stages about growth, later stages involve defense.
Oh, and I noticed that the youtube gamers enjoy it as well.
