About this puzzle
Sheet #3 divides the grid into 31 cages averaging 2.6 cells. 7 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 6, column 2.
The most open cage, 19 in 4 cells, still allows 11 different sets of digits — leave it for later.
2 cages have a single cell, which works like a given.
Where to start
The 10 in 4 cells starting at row 4, column 1 can only be 1 + 2 + 3 + 4.
The 7 in 3 cells starting at row 8, column 4 can only be 1 + 2 + 4.
Every step can be found with cage combinations plus ordinary sudoku logic.
