🧠 How Sudoku Works

Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids contain all of the digits from 1 to 9.

Rules:

  • Each row must contain the digits 1-9 without repetition
  • Each column must contain the digits 1-9 without repetition
  • Each 3×3 box must contain the digits 1-9 without repetition

Solving Strategies:

  • Naked Singles: A cell with only one possible value
  • Hidden Singles: A digit that can only go in one cell in a row/column/box
  • Backtracking: Systematic trial and error with constraint checking
