About this puzzle
Sheet #2 divides the grid into 28 cages averaging 2.9 cells. 3 cages have only one possible set of digits — the natural place to begin.
The largest cage covers 5 cells and adds up to 31; it starts at row 1, column 5.
The most open cage, 24 in 5 cells, still allows 11 different sets of digits — leave it for later.
Where to start
The 7 in 3 cells starting at row 4, column 8 can only be 1 + 2 + 4.
The 4 in 2 cells starting at row 3, column 3 can only be 1 + 3.
At least once you will need the rule of 45: total a row, column or box and subtract the cages that lie inside it.
