Sudoku Notepad and 2016 Calendar

This is the multitasking desktop calendar that keeps Sudoku lovers challenged, entertained, and on the ball, every day of the year. On each page is a Sudoku grid hand-designed by an expert at Nikoli—the Japanese company that created the game—to balance toughness, elegant solvability, and pure addictiveness. And with a daily fill-in to-do list and two mini calendars, Sudoku is as functional as it is fun. The easiest puzzles are printed on weekends, and they increase in difficulty over the course of the week.
