Eliminating numbers from rows, columns, and 3×3 boxes Candidate number 2 is the only one remaining, which is the solution for row 4 column 2. Also, the column corresponding to row 4 column 2 has the numbers 9 and 5 while the corresponding row already has 1 and 6. For instance, the fourth box already has 3, 4, 7, and 8.
