Sudoku is an engaging logic game that helps train the brain and improve thinking skills. However, many players often find themselves repeating the same mistakes, making it harder and more time-consuming to complete a Sudoku puzzle. So, what are some tips to avoid repeating old errors when playing Sudoku? Let’s find out in this article.
Understand the basic rules of Sudoku
First, to avoid mistakes, you need to have a solid grasp of the basic rules of Sudoku: each row, column, and 3×3 box must contain all the numbers from 1 to 9 without repeating. Mastering these rules will help you easily spot mistakes and prevent repeating errors you’ve made before.
Note possible numbers
One of the most important tips is to use pencil marks. When you’re unsure which number belongs in a blank cell, jot down all possible options. This helps you:
- Get an overview of your choices without rushing and making errors.
- Identify certain numbers (naked singles) and potential pairs (hidden pairs).
- Avoid repeating mistakes caused by guessing.
Learn from past mistakes
Whenever you make a mistake, don’t just erase the number and try again. Take some time to analyze why you went wrong:
- Did you miss a number in a row, column, or 3×3 box?
- Did you guess without checking carefully?
- Did you overlook important pencil marks?
This process helps you recognize common patterns of mistakes and gradually improve your skills.
Break the puzzle into smaller sections
If you encounter a difficult puzzle, don’t try to fill in everything at once. Break the puzzle into smaller sections: focus on solving one row, column, or 3×3 box at a time. This approach reduces pressure and prevents mistakes caused by rushing.
Use the elimination technique
Many mistakes happen when players fail to eliminate impossible options. Apply the elimination technique: if a number already appears in a row, column, or 3×3 box, remove it from the other cells. This method minimizes errors and increases accuracy.
Stay calm and practice regularly
Finally, repeating mistakes often comes from rushing or stress. Stay calm and practice Sudoku regularly. Over time, your skills will improve, and repeated mistakes will decrease.
To avoid repeating mistakes when playing Sudoku, you need to understand the basic rules, use pencil marks, learn from errors, break the puzzle into smaller sections, apply elimination techniques, and stay calm. By following these tips, solving Sudoku becomes more enjoyable, logical, and accurate.
