It s a year of top-of-the-line Sudoku for puzzle lovers. From Nikoli, the Japanese company that developed the addictive numbers game into an international phenomenon, this calendar delivers a year of visually appealing full-color puzzles that strike the perfect balance between challenge, solvability, and entertainment. Generated by hand, not by computer, each is singularly elegant and intuitive like facing off against a master Sudoku maker, step by step. The puzzles begin easy each weekend, and increase in difficulty over the course of the week. Answers are printed on the reverse side of each page."
