Features: Sudoku is the newest, most popular, most interesting, and fun digital puzzle game of the 21st century. Sudoku has stood out among various word games and become a trend because it is fundamentally different from traditional word games. Sudoku transcends language barriers and does not require players to have any mathematical knowledge. All you need to do is fill the numbers 1 to 9 into nine 3x3 grids, ensuring that each number appears only once in each row, column, and 3x3 grid. Some numbers are pre-filled in the puzzle, while the rest are left blank. Players must logically deduce what numbers should go in the empty cells based on the distribution of the given numbers. Sudoku swept across the UK, becoming a popular mass game and a hot topic of conversation after meals. British newspapers widely published this game as a way to attract readers. Following The Times, newspapers such as The Daily Mail, The Daily Telegraph, The Independent, The Guardian, The Sun, and The Mirror successively featured Sudoku. British bookstores also rushed to publish Sudoku books, which once occupied spots on the bestseller lists of major bookstores.
