    Rows count from the top and columns from the left. A box is one of the six 2×3 blocks, named by where it sits: top-left, top-right, middle-left, middle-right, bottom-left and bottom-right.

    1. The middle-left box still needs a 3. Column 2 already has one, so the 3 can only go in row 4, column 3.
    2. The middle-left box still needs a 5. Row 3 already has one, so the 5 can only go in row 4, column 2.
    3. Only a 2 is missing from the middle-left box, so it goes in the last empty cell, row 3, column 2.
