Sudoku Challenge

Exercise your logic skills with classic number puzzles

How to Play:

  • The Goal: Fill the 9×9 grid so each row, column, and 3×3 box contains digits 1-9
  • The Rules: Each number can appear only once in each row, column, and 3×3 box
  • Four Difficulty Levels: Easy, Medium, Hard, or Expert - each with progressively fewer starting numbers
  • Select & Fill: Click a cell, then click a number button to fill it in
  • Hints Available: Get a hint to reveal one correct number when you're stuck
  • Check Progress: Verify your answers - incorrect entries will be highlighted in red
  • Track Your Time: See how fast you can solve each puzzle

💡 Pro Tip: Look for rows, columns, or 3×3 boxes with the most numbers already filled in - these are easier to complete!
