Good Fences

Good Fences is a fiendishly difficult solitaire game that combines Sudoku-like logical deduction with geometric intuition and spatial reasoning. The idea is simple: build a Good Fence by surrounding a shape with copies of itself. Sound easy? Well, OK, sometimes we throw in a gimme to lull you into a false sense of security. But can you then completely surround a shape using the smallest possible number of copies? How about the largest possible number? And if you can do that, can you also build a fence around your fence, that is, a second level of surround? You'll discover that some of these challenges require persistence and ingenuity.
