About this puzzle
A 11×11 field with 72 white cells in 42 runs, and clues from 3 to 40. 15 runs have only one possible set of digits.
The longest run has 7 cells and adds up to 40, with 2 possible combinations.
Where to start
The 21 down 6 cells starting at row 7, column 4 can only be 1 + 2 + 3 + 4 + 5 + 6.
The 21 down 6 cells starting at row 7, column 8 can only be 1 + 2 + 3 + 4 + 5 + 6.
Some runs only resolve when you test which of their combinations still fit the crossing runs. Notes make that bookkeeping easy.
