The goal of Sudoku is to fill a 9×9 grid with numbers so that each row, column and 3×3 section contain all of the digits between 1 and 9.
Now you no longer need to search the web for new puzzles.
When you see a naked pair, it is safe to eliminate those two numbers from all other cells in the row, column, or region the pair reside in.
