Notes on this puzzle
Kakuro #5410 is a 11×11 field with 82 white cells split into 48 runs: 22 across and 26 down.
15 of the 48 runs can be filled with only one set of digits:
- 3 in 2 → 1 + 2
- 4 in 2 → 1 + 3
- 17 in 2 → 8 + 9
- 6 in 3 → 1 + 2 + 3
- 7 in 3 → 1 + 2 + 4
- 23 in 3 → 6 + 8 + 9
The longest run is 7 cells long and 14 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 3 up to 41, with an average of 17.6.
Where to beginA good first target is the cell at row 2, 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.
