The core rules of Sudoku are simple to learn but endlessly rewarding to master. Your goal is to fill every cell of a 9x9 grid with digits 1 through 9, following three key rules: no number can repeat in any single row, no number can repeat in any single column, and no number can repeat in any of the nine 3x3 subgrids that make up the full grid. Start with easier difficulty levels if you are new to the game, to practice basic elimination techniques, then work your way up to harder levels that require more advanced strategies like pencil marking and cross-referencing across the grid. If you get stuck, you can use the built-in hint system to get a nudge in the right direction, but you will get the most satisfaction from solving each puzzle on your own.
