How to solve Sudoku?

Sudoku puzzles are solved by placing numbers from 1 to 9 into a 9x9 grid so that each row, column, and 3x3 subgrid contains all digits without repetition. Here's a straightforward approach:

  • Start with Given Numbers: Begin by identifying the numbers already provided in the puzzle.
  • Elimination: Deduce possible numbers for empty cells by considering what's already in the same row, column, and subgrid.
  • Fill in Obvious Choices: If there's only one possible number for a cell, fill it in.
  • Use Candidates: List possible numbers for each empty cell, then use logical deduction to find the correct one.
  • Repeat: Keep eliminating possibilities and filling in numbers until the puzzle is solved.
  • Check: Double-check each row, column, and subgrid to ensure all numbers from 1 to 9 are present without repetition.
  • Practice: Regular practice improves your skills.
