Features: Sudoku is the newest, most popular, most interesting, and fun digital guessing game of the 21st century. Sudoku has stood out among various word games and become a trend because it is entirely 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 the 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 use logical deduction based on the distribution of numbers in the puzzle to figure out what numbers go in the remaining empty cells. Sudoku swept across the UK, becoming a popular pastime. It became a hot topic of conversation after dinner. British newspapers published this game one after another as a means to attract readers. Following The Times, newspapers such as The Daily Mail, The Daily Telegraph, The Independent, The Guardian, The Sun, and The Mirror also featured it. British bookstores rushed to publish Sudoku books, which also occupied spots on the bestseller lists of major bookstores.
