Twelve towns, twenty cables

Twelve towns and nothing joining them. You have twenty cables. Lay them wherever you like, then knock towns out and watch what is left of the network. Spread the cables evenly, note what happens; pile them onto two or three towns, and note what happens then. Same budget, different survival.

Click two towns to lay your first cable.
