What is Sudoku?
Sudoku is the classic 9×9 number-placement puzzle hosted here via sudoku.com: fill empty cells so every row, every column, and every 3×3 box contains the digits 1–9 once. No arithmetic. Logic only. A given digit is locked; your job is the rest. One illegal placement can quietly poison three houses.
This Play button opens the sudoku.com hub, not NYT Sudoku, not LinkedIn Mini Sudoku (6×6), and not the separate Daily Sudoku challenge URL in this catalog. Same ancient rules, different editorial grids and UI.
Sudoku Game Rules
Use only 1–9. No repeats in any row, column, or box. Starting clues stay. A number that fits a row can still be banned by its box. Valid published puzzles can be finished without guessing, though humans still guess and regret it. Difficulty on sudoku.com is a label about how scarce the givens and techniques feel, not a different rule set. Finish when the grid is full and every house is a permutation of 1–9.
- Fill Sudoku so each row, column, and 3×3 contains 1–9 once.
