Sudoku Logic

You play by clicking on an empty square in the 9x9 grid and then selecting a number from 1 to 9. The core objective is to fill the entire grid so that each row, each column, and each of the nine 3x3 blocks contains all the digits from 1 to 9 without any repeats. The game typically provides a timer and a mistake counter, which adds a quiet layer of pressure. Some versions might highlight conflicting numbers or offer pencil marks for notes, but the interaction remains minimal and focused. The pacing is entirely your own; you can stare at the puzzle for minutes or click through quickly if you see the pattern. It feels like a clean, quiet exercise in order, a small system of logic you complete one square at a time.
