How to Play
Fill the 9x9 grid so that every row, column, and 3x3 box contains the digits 1 through 9 exactly once. Click a cell to select it, then type a number to place it. Use pencil mode to write small candidate numbers as notes. Choose from four difficulty levels: Easy, Medium, Hard, or Expert. Use hints if you get stuck — but each hint reduces your score. Press Undo to reverse your last move.
About Sudoku
Sudoku is the world's most popular number puzzle, enjoyed by millions daily in newspapers, apps, and online. Despite involving numbers, Sudoku is a pure logic puzzle — no arithmetic required. Each puzzle has exactly one solution that can be found through deduction alone. PlayMore.gg offers procedurally generated puzzles at four difficulty levels, a pencil mark system for tracking candidates, save states to continue later, and daily challenges with shared puzzles for competitive solving.
Scoring
Scoring is based on difficulty and time. Higher difficulties award more base points: Easy (1x), Medium (2x), Hard (3x), Expert (4x). Your final score is calculated as (base_points x difficulty_multiplier) / time_in_seconds. Using hints deducts 1000 points each. The fastest solvers on the hardest difficulty top the leaderboard.
