This is not the puzzle game they advertise. It is a money grab PVP war game. Constant resource and gem drains. With the latest expansion to k40, single players are running an entire SVS by themselves,,,so all you can do is sit in a 3-day bubble. Top players will spend tens of thousands of dollars... probably at least $30k. Also, lag always seems to hit at worst time during pvp, even with gigabit internet with 1ms ping. Toxic players on a number of servers..
