Notes on this puzzle
Kakuro #5106 is a 6×6 field with 24 white cells split into 16 runs: 8 across and 8 down.
6 of the 16 runs can be filled with only one set of digits:
- 3 in 2 → 1 + 2
- 4 in 2 → 1 + 3
- 16 in 2 → 7 + 9
- 17 in 2 → 8 + 9
- 30 in 4 → 6 + 7 + 8 + 9
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 3 up to 30, with an average of 15.1.
Where to beginA good first target is the cell at row 3, column 1 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.
