Slitherlink & Masyu

One of the familiar pleasures of childhood is solving mazes. Now Nikoli presents mazes for grownups—mazes without walls! In Slitherlink, the diagrams are open grids, with numbers scattered through them; the solver has to connect the dots in a closed loop, with each number indicating exactly how many lines must surround it. In Masyu, the task is to draw a path through black and white circles, making a right-angle turn at each black circle, and going straight ahead through every white one. Don’t let the simple rules fool you--these challenges are guaranteed to keep puzzle fans delightfully distracted for hours on end.
