Cross Sums

Cross Sums is a digital adaptation of the logic puzzle Kakuro, also known as Cross Sums. In Kakuro, players fill blank cells in a grid with digits from 1 to 9 so that the sum of each horizontal or vertical block matches the clue provided, with no repeated digits within any block. Before starting a new puzzle, players can adjust the difficulty level - choosing from four distinct settings - select the grid size, and customize the colors of the user interface elements.
