Sudoku-like puzzles appeared in late-19th-century France, while modern Sudoku was created by Howard Garns in 1979 as Number Place and later popularized in Japan and internationally. The game has more than 6.67 sextillion possible completed grids, and the largest multi-Sudoku puzzle featured 280 grids. “Sudoku” entered the Oxford English Dictionary in 2006, and Wang Shiyao set a 54.44-second solve time at the 2018 World Sudoku Championship.
