Say goodbye to crossword puzzles and hello to the addictive game of numbers in Ancient Sudoku. Originally a pen-and-pencil game from Japan, Sudoku traveled west and started a brainteaser craze. Played on a 9x9 grid, the object is to fill the squares so that each row and column contains the numerals 1 through 9. Ancient Sudoku includes classic game play as well as multiple variations of regular Sudoku, such as filling the blanks with the correct color ball instead of numbers. Players can also create new puzzles to share with friends and print them out to play on the go. An in-game tutorial is included, and game play can be adjusted to different difficulty levels, but for those in need of a clue, an auto pencil hint tool will offer suggestions. Multiple tile sets and unlimited levels add to the challenge and will keep gamers busy for hours. ~ Gracie Leach, All Game Guide
