Sometimes I think I should create a separate tag for puzzles so full of cages there’s no other constraint. Like Predator 6, and this one. If I ever do, I should update this text, since it will no longer apply.
Rules:
Normal Sudoku rules apply.
Digits in cages do not repeat, and sum to the small number in the top left corner of the cage, if given.
Estimated difficulty: 1.5 out of 5
