As its name implies, this game is actually a Windows Phone 7 version of the highly popular Sudoku number puzzle, originally created by Howard Garns back in 1979.
Here are the rules:
Fill the grid so that the numbers 1 through 9 appear in each row.
Fill the grid so that the numbers 1 through 9 appear in each column.
Fill the grid so that the numbers 1 through 9 appear in each 3x3 box.
A complete Sudoku puzzle contains the numbers 1 through 9 in every row, column, and 3x3 box.
