About this puzzle
Sheet #11 divides the grid into 21 cages averaging 3.9 cells. 2 cages have only one possible set of digits — the natural place to begin.
The largest cage covers 6 cells and adds up to 39; it starts at row 6, column 3.
The most open cage, 25 in 5 cells, still allows 12 different sets of digits — leave it for later.
Where to start
The 39 in 6 cells starting at row 6, column 3 can only be 4 + 5 + 6 + 7 + 8 + 9.
The 15 in 5 cells starting at row 3, column 2 can only be 1 + 2 + 3 + 4 + 5.
Expect to lock digits between cages and lines and to use pairs. Write notes in the big cages early.
