▦ About Sudoku

The modern Sudoku that we know today was popularized in Japan in the 1980s under the name "Number Place". It gained international recognition in the early 2000s, thanks to the efforts of a New Zealand judge, Wayne Gould, who helped to publish Sudoku puzzles in British newspaper "The Times". Since then, Sudoku has become a beloved pastime for millions, appearing in newspapers and books worldwide, challenging players of all ages and skill levels. But books such as Will Shortz Puzzle Books or Famous Frog Sudoku, and newspapers columns like Sudoku New York Times (NYT) or Sudoku Los Angeles Times, only have a limited number of puzzles that you have to carry around to play. Online Sudoku platforms like sudoku369.com solve this problem by giving you access to unlimited Sudoku puzzles from anywhere around the world.

▦ How to Play

As you can see that the 9x9 classic sudoku puzzle has 81 cells, among them some are already filled while others are empty. Simply fill the empty cells in the grid with numbers from 1 to 9. Remember, each number can only appear once in each row, column, and 3x3 sub-grid. Use logic and deduction to strategically place the numbers and solve the puzzle. Just pick a cell and place the correct number based on the logic from the filled numbers. It's that simple!

▦ Rules

There are some very simple rules to keep in mind while solving sudoku puzzles:

  • Fill each cell in the grid with a number from 1 to 9.
  • Each number can only appear once in each row, column, and 3x3 sub-grid.
  • The initial numbers given in the puzzle cannot be changed.

Remember, every move counts, so think carefully before placing a number.

▦ Tips

Need some guidance? Here are some tips to help you solve sudoku:

  • Start with the easier puzzles and gradually move to higher difficulty levels.
  • Focus on the cells surrounded by the most pre-filled numbers.
  • Scan the grid for numbers that can only go in one place based on the existing numbers.
  • Use the process of elimination to narrow down the possibilities for each cell.
  • Take your time and avoid making random guesses.
  • Utilize the "Hint" feature sparingly, as each use incurs a mistake count.
