You cannot repeat a numeral in any row, column, or 3 x 3 square.

Like most online sudoku games, this one has a means of adding guesses.
Guess numbers appear as tiny versions of the numbers. You can place in as many of them as you need throughout the puzzle to help you extend the givens to deduce which numbers belong in other locations.
Use these tiny notes to keep track of the possible numbers that could belong in a specific cell.
Tap on a small number once to insert it & tap again to remove it, or select the delete button to clear the contents of the highlighted cell. If you place the final number in a cell it clears out all guess numbers.
