Quick Answer

To solve Sudoku, use the process of elimination: check rows, columns, and 3x3 boxes to find which numbers can fit in each empty cell. Start with cells that have the fewest possibilities.

Detailed Answer

Sudoku is a logic puzzle where you fill a 9x9 grid so every row, column, and 3x3 box contains the digits 1-9 exactly once. Winning strategies for beginners: Start with the easiest cells — find rows, columns, or boxes that already have many numbers filled in. Use scanning: look at each row and column to eliminate numbers that can't go in a cell. Use the 'naked single' technique: if a cell can only contain one possible number based on row, column, and box constraints, that number goes there. Intermediate techniques: Hidden singles: if a number can only go in one cell within a row, column, or box, it must go there. Box/line reduction: if a number in a box is restricted to one row or column, eliminate it from that row/column in other boxes. Advanced techniques include naked pairs, hidden triples, and X-wing patterns. The most important tip: never guess. Every Sudoku has a logical solution. If you're stuck, re-examine the grid systematically rather than trying random numbers.
