A View to a Kill (Perspective Killer Sudoku)
(Published on 29. July 2020, 13:53 by CannyK9)
The previous puzzle required working out the configuration of the grid before properly using the constraint, which turned out to be harder than I thought and involved a lot of trial and error.
In this puzzle the configuration is given and there's no bifurcation, so you get to have unfettered fun with the new constraint!
1) Normal Sudoku rules apply.
2) Normal killer rules apply, the contents of each cage must sum to the total in the top-left of the cage.
3) Imagine some of the 3x3 zones have risen up out of the grid, so you can also see the cell values on the sides. Raised zones are white, flat zones are grey.
When viewing from all four sides, the completed puzzle must show the numbers 1-9 along each side:

Dropped the difficulty, now I've gotten a bit more used to the grading

Interessante Idee, und toll, wie die Regeln ineinander gegriffen haben.

Hi 21Yasindayim, sorry about the multiple solutions, did the 7 cage I added to box 3 after posting fix it? I'm not seeing it otherwise, r6c7 shouldn't be a 3!

No worries. Nice puzzle otherwise, good use of the ruleset to implement some interesting logic.

Thanks very much for spotting that - once upon a time the bottom-left cage was fixed, but it's hard to keep cages in boxes without them giving the game away and it came undone! I should've know it was those cells in box 6, I need a stranger shape~

Added extra cage to remove ambiguity

Curious! It's difficult to change anything without breaking everything, would you be able to tell me the offending cells? I'm glad this was more approachable in any case.
