Slitherlinks

I'm addicted to slitherlinks. It's a logic puzzle that is a cross between a maze and a dot-to-dot. "The puzzle consists of a grid of dots, with some clue cells containing numbers. You connect horizontally or vertically adjacent dots to form a meandering path that forms a single loop or "Slitherlink." The loop must not have any branches and must not cross itself. The clue numbers indicate how many lines surround the cell. Empty cells may be surrounded by any number of lines (from 0 to 3). "

There are a lot of them here. I started out with the 7x7 and then the 10x10s. Now I'm working the 20x20 easy puzzles. (I can do the 7x7 and 10x10 pretty easily now.) With the 20x20 I start by using a colored pencil to mark all the lines I'm sure of at first glance and then come back with regular pencil to complete the rest. Sometimes I even color them in afterwards.
