Number Sum Game
--- How to Play: Match the sums of selected numbers in each row and column to the target numbers displayed in black cells at the top and left. Click on the blue cells to change their state: Green: Number is selected and contributes to the row and column sum. Red: Number is marked as not to be used in the sum (typically for cells where the original grid value is zero). You win when the sum of the green numbers in each row and column equals the target numbers, and all originally zero-valued cells are marked red. Refresh the webpage for new puzzle.
