🧩 Sudoku

Welcome to The Howard IT Sudoku Challenge! Your goal is to fill every row, column, and 3×3 box with the numbers 1 through 9—without repeating any digit. Race against the clock to complete the entire grid as quickly and accurately as you can—each second shaved off your time boosts your score. Use pencil marks and hints wisely, because mistakes and extra hints will subtract points from your final total.

• Select a difficulty: Easy, Medium or Hard—more empty cells means a tougher puzzle.
• ✎ Pencil mode: Toggle “Pencil” to jot small notes before committing your final answer.
• 💡 Hint: Reveal a random correct number when you’re stuck (but it costs points!).
• Time & Score: The faster you solve and the fewer mistakes you make, the higher your score.
• Leaderboard: Top scores are saved locally—see if you can land on the podium!

Good luck, have fun, and may the best puzzler win!
