Never ever say something like: «9 can't go on an arrow» Because it will give idea to the constructors ! And they will come up with a rule that permit it! Like the rule: «In the grid there is 9 unique doubler cell...» 😉

Ah, but I LOVE it when setters confound my expectations! I also try to say things like in NORMAL sudoku puzzles, 9 can't go on an arrow, but I do forget sometimes :D.
