The Jumbo Book of Japanese Puzzles - The Puzzle Society

A collection of four hundred puzzles - six different types of mind-bending games - ranging in difficulty levels so that players of every level will be challenged.

Features include a complete answer key along with short, illustrated tutorials for each game - which proves particularly useful for the less familiar challenges, including:

Hitori: The ultimate logic teaser. Begin with a complete Sudoku grid and the object is to "paint" out blocks so that no number appears twice in any row or column.

Masyu: A charming but sophisticated invention where you are required to "string" black-and-white "pearls" with a series of vertical and horizontal lines that form a continuous loop.

Nurikabe: Beginning with a grid of squares scattered with numbers seemingly placed at random, the idea is to paint the black squares to make walls, leaving patches of white behind.
