About Sudoku
Sudoku is a logic-based number puzzle that originated in Japan. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids contains all of the digits from 1 to 9.
Despite the name meaning "single number" in Japanese, Sudoku is a game of logic, not mathematics. No arithmetic is involved - only logical deduction!
Each puzzle has a unique solution and can be solved without guessing. Improve your logical thinking and problem-solving skills while having fun!
