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.
