With these two all-new volumes, Japan's puzzle master supreme presents a cornucopia of never-before-seen ultimate logic games. Along with a number of his original O'Ekaki puzzles, Nishio has assembled a medley of mazes and puzzles so entertaining, gamers may never want to put their pencils down! Each oversized volume features dozens of Alconne, True Arrows, End View and Sky Scraper Puzzles and is capped by 10 of Nishio's most sinister Sudoku grids. This may well be his most fiendish book yet.
