Daddy Of All Gattai.
Ruud's challenge about the biggest kind of Gattai in 2007: 85 overlapping Sukoku's, that inspired me some years ago to solve these kind of puzzles, by hand.
His 85-Gattai with vanilla Sudoku's can be solved with naked/hidden singles and pointing/claiming.

All puzzles below are similar 85-Gattai's. There is a way of solving to use Singles Only (no special methods needed).
So the SE rating is 1.5 at most. But that is a very very very subjective rating.
All are symmetrical up/down and left/right. That should things make a bit easier. But it is not.
A DOAG contains a total of 5589 cells.
Puzzle 1: All Windoku's and 4747 cells to solve. Do not start in the NorthWest but rather in the South.
Puzzle 2: All SudokuX's and 4639 cells to solve.
Puzzle 3: All Clovers (=Windoku+Asterisk) and 4949 cells to solve.
