Notes on this puzzle
This medium kakuro fits 38 cells to fill into a 8×8 frame, tied together by 21 clue squares.
8 of the 24 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
- 29 in 4 → 5 + 7 + 8 + 9
- 34 in 5 → 4 + 6 + 7 + 8 + 9
The longest run is 5 cells long and 10 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 3 up to 35, with an average of 17.3.
Where to beginA good first target is the cell at row 2, column 6 of the field: the two runs crossing there settle it. Use the crossings: a cell's digit must be allowed by both its runs.
