The Original Sudoku 2019 Calendar

The original Sudoku calendar is more than just a year of Sudoku—it’s the best year of Sudoku with puzzles that are handcrafted by the experts at Nikoli, the Japanese creators of the game. Each of the more than 300 full-color, brain-boosting puzzles is crafted by hand, providing a level of utterly absorbing and addictive fun that computer-generated puzzles just can’t match. Every weekend starts off with a simple puzzle to ease you in; then, as the week continues, the puzzles get increasingly difficult, encouraging you to kick up your problem-solving skills as you go. A perfect gift or desk activity for puzzle enthusiasts.

Nikoli is “widely recognized as the world’s most prolific wellspring of logic games and brainteasers.”—The New York Times
