Notes on this puzzle
Kakuro #5406 is a 11×11 field with 73 white cells split into 44 runs: 19 across and 25 down.
14 of the 44 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
- 23 in 3 → 6 + 8 + 9
- 10 in 4 → 1 + 2 + 3 + 4
The longest run is 6 cells long and 18 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 3 up to 39, with an average of 16.3.
Where to beginA good first target is the cell at row 2, column 4 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.
