About Sudoku Pro

Sudoku is the world’s most popular number-placement puzzle, enjoyed by hundreds of millions of people across every age group and background. The rules are simple enough to explain in one sentence — place the digits 1 through 9 in every row, column, and 3×3 box without repetition — but the depth of logical deduction required to solve harder puzzles is genuinely staggering.

Sudoku Pro serves a fresh daily puzzle for each difficulty level: Easy (for beginners learning the basic techniques), Medium (introducing elimination chains), Hard (requiring more advanced methods like X-Wing and Swordfish), and Expert (demanding the full arsenal of logical techniques). Each daily puzzle is the same for all players worldwide, making it easy to compare completion times with friends.

Beyond daily challenges, the game includes an unlimited random puzzle mode so you can keep playing after finishing the day’s set. The clean interface supports both tap-to-fill and pencil-mark notation, with optional auto-highlighting to indicate which rows, columns, and boxes a selected digit affects. Whether you have five minutes on your lunch break or an hour to dedicate to a fiendish Expert grid, Sudoku Pro delivers a polished, distraction-free puzzle experience.
