About this puzzle
A 10×10 field with 64 white cells in 40 runs, and clues from 3 to 35. 12 runs have only one possible set of digits.
The longest run has 5 cells and adds up to 24, with 11 possible combinations.
Where to start
The 35 down 5 cells starting at row 2, column 6 can only be 5 + 6 + 7 + 8 + 9.
The 34 across 5 cells starting at row 7, column 7 can only be 4 + 6 + 7 + 8 + 9.
Some runs only resolve when you test which of their combinations still fit the crossing runs. Notes make that bookkeeping easy.
