Complete rules
Goal: Connect all tree nodes into one network. Rules: - Connections are straight and may run horizontally, vertically, or diagonally. - The number inside a node gives its exact total number of connections. - Only one line may connect the same pair of nodes. - Lines cannot cross, overlap, or pass through another node. - Every node must belong to the same connected network.
