Play this fun and easy-to-use Sudoku game on your iPhone or iPad. Great for beginners and a challenge for experts. It has beautiful graphics, smooth game play and subtle sound effects. Sudoku is a number puzzle game where you try to fill in the blanks. Each digit (from 1 to 9) can only appear once in each row, column, or 3x3 sub-grid. There is only one solution for each puzzle. Here's an example: If a row looks like this: 1 3 _ 4 5 6 8 9 7 Then the number 2 is the only possible answer for that empty space, because the numbers 13456789 are all already in that row. By looking to see which numbers are already in a row, column and 3x3 sub-grid you can figure out what numbers go in each cell. (It sounds more complicated than it is! The "SIMPLE" level puzzles make it pretty easy to get started.) If you love puzzle and card games try my other games too!
