Notes on this puzzle
Kakuro #5104 is a 6×6 field with 22 white cells split into 16 runs: 8 across and 8 down.
3 of the 16 runs can be filled with only one set of digits:
- 6 in 3 → 1 + 2 + 3
- 10 in 4 → 1 + 2 + 3 + 4
The longest run is 4 cells long and 6 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 5 up to 20, with an average of 10.4.
Where to beginA good first target is the cell at row 5, column 4 of the field: the two runs crossing there settle it. Every run here can be settled from its combinations; check the small and large totals first.
