In Daily Number Sums, players face a structured grid filled with single-digit numbers. Surrounding the grid—at the end of each row and column—are target sum totals. Your objective is simple on paper but deeply strategic in practice: decide which numbers in the grid to keep and which to erase so that the remaining numbers in every row and column add up exactly to their corresponding target values.
