Grid Sum – Easy

Visual strategy: lightly pencil in candidate values only when you are confident — avoid guessing.

  • Identify the “almost complete” row/column.
  • Calculate the missing value.
  • Recalculate the crossing total to confirm.

Finish: once the grid is full, re-add every row and column to confirm perfection.
