Sudoku Classic – Daily Brain Puzzle
Each number can only appear once in each row, column, and 3x3 box.
Use logic and elimination to solve the puzzle.
Good luck!
Start by filling in any number that appears only once in a row, column, or 3x3 box, as these are the easiest to solve. Use the hint system only when you're truly stuck, as over-reliance may reduce the challenge. Always double-check your entries—mistakes in Sudoku can block progress, so verify each number fits the logic of its row, column, and box.
