Notes on this puzzle
This medium kakuro fits 32 cells to fill into a 8×8 frame, tied together by 16 clue squares.
4 of the 20 runs can be filled with only one set of digits:
- 6 in 3 → 1 + 2 + 3
- 7 in 3 → 1 + 2 + 4
- 23 in 3 → 6 + 8 + 9
The longest run is 5 cells long and 4 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 6 up to 28, with an average of 15.8.
Where to beginA good first target is the cell at row 1, column 4 of the field: the two runs crossing there settle it. Use the crossings: a cell's digit must be allowed by both its runs.
