Do I need math skills to play Sudoku?
No. Sudoku is a logic puzzle; the digits are just symbols. You could play with letters or colors.
What is a good beginner strategy?
Focus on one digit at a time and scan every row, column, and box to find where it must go.
Can every Sudoku be solved without guessing?
Properly designed Sudoku puzzles require only logic. If you find yourself guessing, look for a technique you missed.
How do pencil marks help?
They let you track small candidate numbers in each cell, making hidden patterns easier to spot.
What makes a Sudoku expert-level?
Fewer starting clues and the need for advanced techniques like X-Wing, swordfish, or coloring.
