Lesson 2

Nearly Complete

The rule

When a row, column, or box has two empty cells, if one of its two missing numbers is already used in a row, column, or box containing one of those cells, it cannot go in that cell, so the other missing number must go there.

Step by step

  1. This row only needs 1, 2.
  2. 2 is already in the same column, so it cannot go in this cell.
  3. Only 1 remains for this cell!
