About this puzzle
A 10×10 field with 54 white cells in 40 runs, and clues from 3 to 31. 14 runs have only one possible set of digits.
The longest run has 5 cells and adds up to 31, with 5 possible combinations.
Where to start
The 29 across 4 cells starting at row 2, column 3 can only be 5 + 7 + 8 + 9.
The 30 down 4 cells starting at row 3, column 10 can only be 6 + 7 + 8 + 9.
Sum combinations alone finish this sheet: start with the single-combination runs and follow the crossings.
