➕ Kakuro
A cross-sum puzzle. Fill each run of white cells with digits 1–9 that add up to the clue — and never repeat a digit within the same run.
A clue cell shows the sum for the run going right (top number) and down (bottom number). Click a white cell and type 1–9. No digit repeats within a run; every run must hit its sum.
