Drag from your node to another to open a supply line; swipe across a line (or tap it) to cut it.Nodes grow & shrink with their value (max 64). Line limit: 1 (<10), 2 (10–30), 3 (>30). No free slot = no new line.Bigger nodes attack & defend stronger. A unit's strength is set by its origin (shown by its color & size).A node at 64 relays extra friendly units out its lines. Neutral nodes grow but never attack.Lines need a clear path; when two nodes attack each other the stronger stream breaks through. Enemies idle 15s.
