# How to become sudoku puzzles champion?

Sudoku is a puzzle game that involves filling in a grid of numbers so that each row, column, and 3x3 block contains all of the numbers from 1 to 9. The world record for solving a Sudoku puzzle is held by a computer program called "sudoku.com," which was able to solve a standard 9x9 Sudoku puzzle in just 0.6 seconds.

To try to beat the world record, you will need to be extremely fast and efficient at solving Sudoku puzzles. There are several strategies and techniques that can help you improve your Sudoku-solving skills, including the following:

1. Look for the "singles" or numbers that only have one possible location in a row, column, or block. These numbers can be filled in immediately, which will help you make progress on the puzzle.

2. Use the "naked pairs" technique to eliminate potential solutions for a particular number in a row, column, or block. For example, if two squares in a row, column, or block both have the same two possible numbers, then those numbers can be eliminated as possibilities for any other square in that row, column, or block.

3. Use the "hidden pairs" technique to identify and fill in numbers that are uniquely determined by the current state of the puzzle. For example, if there are only two squares in a row, column, or block that can contain a particular number, and those squares also have only one other possible number each, then those numbers can be filled in.

4. Practice, practice, practice! The more Sudoku puzzles you solve, the faster and more efficient you will become at solving them. You can find many Sudoku puzzles online or in puzzle books to practice with.

5. By using these strategies and techniques, and by practicing regularly, you may be able to improve your Sudoku-solving skills and potentially beat the world record. However, keep in mind that the world record is held by a computer program, so it may be very difficult to beat.

### Is sudoku good for my health?

Sudoku, like any form of mental exercise, can potentially have some benefits for your health. For example, solving Sudoku puzzles can help improve your concentration, logical thinking, and problem-solving skills. These skills can transfer to other areas of your life, such as work or school, and can help improve your overall cognitive function.

Additionally, Sudoku can help keep your brain active and engaged, which can potentially slow down the decline in cognitive function that often occurs as we age. By challenging your brain with mentally stimulating activities like Sudoku, you may be able to maintain your cognitive abilities and even improve them over time.

However, it's important to remember that Sudoku is just one form of mental exercise, and it should not be relied on as the sole form of cognitive stimulation. It's important to engage in a variety of activities that challenge your brain, such as reading, writing, learning a new skill, or playing a musical instrument. These activities can also provide mental and cognitive benefits, and can help keep your brain healthy and active.
