Kakuro
Kakuro is a crossword-style arithmetic puzzle that blends numbers and logic. Enter digits from 1 to 9 into the white cells so that the sum of each horizontal or vertical "run" matches the clue in the shaded cell to its left or top. Crucially, a digit cannot be repeated within the same run. Use logic to determine which combinations fit the available space. Tap play to open the full game.
