Sudoku is a classic logic-based number puzzle game that originated in Japan and has become one of the world's most popular puzzle games. Players fill a 9x9 grid divided into nine 3x3 subgrids, ensuring that each row, each column, and each subgrid contains all digits from 1 to 9 without any repetition. The puzzle begins with some numbers pre-filled as clues.
Players strategically fill in the empty cells of a partially completed 9x9 grid with numbers from 1 to 9. The key rules are: no number can repeat in any row, no number can repeat in any column, and no number can repeat in any of the nine 3x3 subgrids. Players use logical deduction, pattern recognition, and elimination techniques to solve the puzzle.
Rule 1: Each row must contain numbers 1-9 without repetition.
Rule 2: Each column must contain numbers 1-9 without repetition.
Rule 3: Each 3x3 box must contain numbers 1-9 without repetition.
Rule 4: The solution must be unique - only one correct arrangement exists.
Rule 5: Puzzles are solved through logic alone, no guessing required.
