Quietly and subtly, Kakuro has become a true favorite among the audience, making this third volume in Heine's puzzle library a logical consequence. Handpicked puzzles ranging from medium to difficult, spread across four extra fine levels. This means 500 instances of high puzzle art for experienced beginners and discerning connoisseurs. Only numbers from 1 to 9, a hint of Sudoku, and a little bit of elementary-level arithmetic combine with the concept of crossword puzzles to create a challenge whose rules couldn't be simpler.
