Medium Sudoku (★★★☆): 10 Large Print Puzzles
Medium puzzles need one more idea. Sometimes, inside one 3×3 box, a number can only go in squares that sit in the same row. You may not know which square yet, but you know the number must be in that row of the box. So it cannot go anywhere else in that row, in the other two boxes. Cross it off there, and a new square often opens up. The same idea works for columns.
