Fight over the territory!
In order to complete a level you have to conquer at least 15% of the territory and collect all flags. To take over a block of the territory you need to trace a line (SWIPE ANYWHERE) between either the frame or the area you have already captured. At the end of the level you get 1 bonus health point for every 15% of the territory under your control. You die every time an atom hits you or your tail or you cross your own or other players tail.
