Sudoku is a number puzzle game played on a 9×9 grid, divided into nine 3×3 subgrids.
The goal is to fill in the grid so that:
- Every row contains the numbers 1-9, without repetition.
- Every column contains the numbers 1-9, without repetition.
- Every 3×3 box contains the numbers 1-9, without repetition.
The game starts with some numbers already filled in. Your job is to complete the grid logically without guessing.
Tips to Win Sudoku
🔹 Start with Easy Numbers – Look for rows, columns, or boxes that already have many numbers filled in. These are easier to solve.
🔹 Use the “Single Candidate” Rule – If a number can only go in one spot in a row, column, or box, place it there.
🔹 Check for Hidden Singles – Sometimes, a number is missing, but only one cell in a row, column, or box can contain it.
🔹 Avoid Guessing – Sudoku is a logical game; every number should be placed with certainty.
🔹 Use Pencil Marks – Write small possible numbers in empty cells and eliminate them as you solve.
🔹 Look for Pairs and Triples – If two or three cells in a row, column, or box contain the same two or three numbers, you can eliminate those numbers from other cells in that section.
🔹 Practice Different Difficulty Levels – Start with easy puzzles and work your way up to harder ones as you improve.
🔹 Stay Patient & Focused – If stuck, take a break and come back with fresh eyes.
Master these techniques, and you’ll solve Sudoku faster and more efficiently!
