A classic Sudoku puzzle. Three different difficulty modes. Puzzles are generated randomly, so you will never get the same puzzle twice.
The objective of Sudoku is to fill every row, column, and 3x3 grid with one occurence of every digit from 1 to 9.
Easy - Cells are marked wrong as numbers are entered
Moderate - Cells are marked wrong only when a duplicate of a number already on the board is entered
Hard - No cells are marked wrong
