Notes on this puzzle
This medium kakuro fits 36 cells to fill into a 8×8 frame, tied together by 20 clue squares.
7 of the 26 runs can be filled with only one set of digits:
- 4 in 2 → 1 + 3
- 17 in 2 → 8 + 9
- 6 in 3 → 1 + 2 + 3
- 7 in 3 → 1 + 2 + 4
The longest run is 4 cells long and 12 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 4 up to 27, with an average of 12.8.
Where to beginA good first target is the cell at row 1, column 8 of the field: the two runs crossing there settle it. Use the crossings: a cell's digit must be allowed by both its runs.
