Sudoku Page-a-Day Notepad and 2015 Calendar

Regular price $12.99

It’s the three-in-one desk accessory that challenges Sudoku lovers with a daily puzzle from Nikoli, the Japanese company that created the original (and still the best!) Sudoku. The hand-generated grids, which begin easy each weekend and increase in difficulty over the course of the week, are brilliantly designed to balance toughness and fun.
