Notes on this puzzle
This medium kakuro fits 36 cells to fill into a 8×8 frame, tied together by 19 clue squares.
9 of the 24 runs can be filled with only one set of digits:
- 3 in 2 → 1 + 2
- 17 in 2 → 8 + 9
- 6 in 3 → 1 + 2 + 3
- 7 in 3 → 1 + 2 + 4
- 23 in 3 → 6 + 8 + 9
- 16 in 5 → 1 + 2 + 3 + 4 + 6
The longest run is 5 cells long and 8 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 3 up to 33, with an average of 14.6.
Where to beginA good first target is the cell at row 4, column 1 of the field: the two runs crossing there settle it. Use the crossings: a cell's digit must be allowed by both its runs.
