About this puzzle
Sheet #7 divides the grid into 30 cages averaging 2.7 cells. 5 cages have only one possible set of digits — the natural place to begin.
The largest cage covers 4 cells and adds up to 28; it starts at row 4, column 4.
The most open cage, 20 in 4 cells, still allows 12 different sets of digits — leave it for later.
Where to start
The 7 in 3 cells starting at row 5, column 5 can only be 1 + 2 + 4.
The 24 in 3 cells starting at row 6, column 8 can only be 7 + 8 + 9.
Every step can be found with cage combinations plus ordinary sudoku logic.
