Hidden Identity Killers
(Published on 3. May 2021, 19:35 by Fluster)
Rules
- Normal sudoku rules apply
- Digits may not repeat in cages
- Cages with the same size must have the same sum and cages with different sizes must have different sums
Background
I enjoy puzzles that seem impossible at first. Lately I have seen a few killer sudokus with no marked cage sums and only some extra rules to help. I played with the idea of how ridiculously minimal rules could still help to solve a puzzle like this. After I realized that you could create some logic even with the rule set you see in this puzzle, I just had to work it through to a complete puzzle.
The puzzle does have a completely logical solve path from start to finish.
Solution code: The bottom row digits of the completed grid without spaces

Excellent puzzle, and congratulations on getting on Cracking the Cryptic! (I figured out the cage sums quicker than Simon, but solved the resulting killer sudoku much more slowly, so he beat me overall.)
You might enjoy my 4-color killer sudoku #2 https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0005V3 , which uses some similar logic.

My algebra 2 teacher is mocking me from beyond the grave. If there's a way to have solved this without using systems of equations, I couldn't find it. Spent twice as long on the scratch pad as I did on the grid.
Truly stunning

I just noticed, that this is your first puzzle on LMG - what a stunning debut!

Took me ages to solve it... I found a logical solving path, but that one must have been way to complicated. Would be interested, how this was supposed to be solved. Anyway: a masterpiece!!
