What is Sudoku?
Sudoku is a logic-based number placement puzzle played on a 9x9 grid. The grid is divided into nine 3x3 subgrids (also called blocks or regions).
The objective is simple: fill the empty cells with numbers from 1 to 9 so that each number appears exactly once in every row, column, and 3x3 subgrid.
Although the rule is straightforward, solving a Sudoku puzzle requires logical deduction and strategy. Puzzles can range in difficulty from easy for beginners to extreme for advanced players.
