Notes on this puzzle
Kakuro #5404 is a 11×11 field with 74 white cells split into 48 runs: 24 across and 24 down.
11 of the 48 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
- 6 in 3 → 1 + 2 + 3
- 34 in 5 → 4 + 6 + 7 + 8 + 9
The longest run is 6 cells long and 22 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 3 up to 34, with an average of 13.9.
Where to beginA good first target is the cell at row 1, column 11 of the field: the two runs crossing there settle it. On a field this size, keep notes on the long runs and recheck them whenever a crossing cell is filled.
