Notes on this puzzle
This medium kakuro fits 46 cells to fill into a 8×8 frame, tied together by 27 clue squares.
9 of the 32 runs can be filled with only one set of digits:
- 4 in 2 → 1 + 3
- 17 in 2 → 8 + 9
- 23 in 3 → 6 + 8 + 9
- 10 in 4 → 1 + 2 + 3 + 4
- 30 in 4 → 6 + 7 + 8 + 9
The longest run is 5 cells long and 14 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 4 up to 30, with an average of 14.7.
Where to beginA good first target is the cell at row 1, 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.
