New to Sudoku?

Sudoku is a classic number puzzle played on a 9×9 grid. The goal is simple: Place digits 1 through 9 so that each row, column, and 3×3 box contains every number exactly once—no repeats.

Use these 4 simple steps to crack any puzzle:

  • •Start with cells that have only one possible number
  • •Scan rows, columns, and boxes to eliminate options
  • •Use notes to track possible numbers
  • •Gradually narrow down choices until the puzzle is complete

No guessing required—just pure logic.
