Notes on this puzzle
This medium kakuro fits 38 cells to fill into a 8×8 frame, tied together by 21 clue squares.
6 of the 24 runs can be filled with only one set of digits:
- 4 in 2 → 1 + 3
- 6 in 3 → 1 + 2 + 3
- 7 in 3 → 1 + 2 + 4
The longest run is 5 cells long and 6 runs have only two cells, which is where the arithmetic is tightest. Clue totals go from 4 up to 32, with an average of 14.
Where to beginA good first target is the cell at row 6, column 3 of the field: the two runs crossing there settle it. Use the crossings: a cell's digit must be allowed by both its runs.
