Totally agree with Kinglsulgard. Solvable without that rule, so why bother introducing it?
@michael_787 @KingIsulgard Thank you for playing and commenting on Doppelgangers. Most times I try to economize on the rules and only provide the bare minimum to solve. For this puzzle, two things come to mind why I didn't. First, the original premise of this puzzle was to see if I could have four boxes whose clues are the same but provide different results. Mission completed. Second, people solve puzzles in different ways. I wanted this to be a 1 or 2-star difficulty for everyone, so I provided extra information to help some that might need it. Peace to you. -Will Power
@michael_787 By the way, I don't see your name on the list of those that have solved this puzzle. I'm not sure if that's a glitch in the website or not. It helps the setter to know how many have solved it, so we can gear future efforts toward puzzles people liked. It's disconcerting to me on any of my puzzles when over 1000 people are shown as solving it on the SudokuPad website, but only 100, or so, bother to log in the solution code here. Thanks. -Will Power
@ Will Power Sorry for the oversight. I have now entered the solution code. A great puzzle, by the way, as all of your puzzles are. Thank you for setting!

11:53 You can just ignore the doppelganger rule, I didn't need it and it just adds unnecessary mental load.

Seeing only 3 possible positions for the digit 9 in the colored boxes helped me deduce that SOME digits MAY be in the same position. Ultimately there was enough disambiguating logic that I didn't need to use this line of the rules at all. Lovely puzzle, possibly 1 star.
@FireTruckFuel You are correct. The rules state that none of the pink boxes has ALL NINE the same. The rule name for NONE of the cells are the same is called DISJOINT GROUPS or DISJOINT SETS. Peace to you. -Will Power
