About Sudoku Battle

A Brief History of Sudoku

Although the name Sudoku is Japanese (meaning 'single number'), the puzzle has roots in 18th-century Switzerland. The modern 9x9 grid format was popularized in Japan in the 1980s and spread globally in the 2000s. Today, Sudoku is one of the most widely played logic puzzles in the world, enjoyed by millions daily.
