Sudoku Assistant helps you solve your Sudoku puzzles (it does not solve them for you).
Sudoku Assistant provides you with a computerized board that helps you keep track of which numbers may appear in each box. Each unknown box displays a list of the possible candidate numbers. When you place a number is a box, that number is automatically erased from the list of candidates for all boxes in the same row, column and area.
As a result, Sudoku Assistant frees you from the mundane task of tracking which numbers may appear in each box and enables you to concentrate on the logic required to solve the puzzle.
