The Fascinating History of Sudoku

While Sudoku as we know it became popular in the late 20th century, its origins trace back to 18th century Switzerland with mathematician Leonhard Euler's "Latin Squares." The modern version was first published in 1979 by American architect Howard Garns, but it gained worldwide popularity in Japan in the 1980s where it got its name "Sudoku" meaning "single number."

Today, Sudoku is recognized as one of the most popular logic puzzles worldwide, with international championships and millions of daily players. Our digital version brings this classic puzzle to your browser with modern features while preserving its timeless appeal.

Pro Tips to Master Sudoku

1. Scan systematically: Look for rows, columns, or boxes with the most numbers filled in first.
2. Use pencil marks: Mentally note possible numbers for empty cells.
3. Look for hidden singles: Numbers that can only go in one particular cell.
4. Eliminate possibilities: Cross out numbers that can't fit based on existing numbers.
5. Practice regularly: Start with easier puzzles and gradually increase difficulty.
