🎮 How to Play Sudoku
Sudoku is a number-placement puzzle that challenges your logical thinking and pattern recognition. The game presents you with a 9x9 grid divided into nine 3x3 boxes, with some numbers already filled in. Your objective is to complete the grid by filling in the empty cells with numbers 1 through 9, following one crucial rule: each number must appear exactly once in every row, column, and 3x3 box.
Start by scanning the grid to identify which numbers are missing in each row, column, and box, then use the process of elimination to determine where each number belongs. As you progress, the puzzle becomes easier because each number you place correctly reduces the possibilities for the remaining empty cells. The game is complete when every cell is filled correctly, with no duplicates in any row, column, or box.
Sudoku requires no math skills—just pure logic and careful observation. Whether you're a beginner tackling easy puzzles or an expert conquering the most challenging grids, each completed puzzle delivers a satisfying sense of accomplishment.

💡 Tips & Strategies
- 1
Start by scanning for rows, columns, or boxes that already have 6-8 numbers filled in, as these will have fewer possibilities and are easier to complete first
- 2
Use pencil marks or notes to track possible candidates for each empty cell, then eliminate options as you fill in more numbers
- 3
Look for 'naked singles'—cells where only one number is possible—and 'hidden singles'—numbers that can only go in one place within a row, column, or box
- 4
Focus on one number at a time and scan the entire grid to see where that specific number can and cannot be placed based on existing placements
- 5
If you get stuck, step back and review your recent entries for errors, or try a different section of the grid to gain fresh perspective and new solving opportunities
