Primes and 159s [159 Killer Sudoku]
(Published on 22. May 2022, 05:11 by wisty)
This is my first real puzzle! Hope you enjoy it :)
Rules:
Normal sudoku rules apply. (place a digit in each cell such that every column, row, and marked 3x3 box contain each digit exactly once)
For columns 1, 5, and 9, digits in column X index the column where X appears in that row. As an example, if r8c9 was a 3, r8c3 would be a 9.
Digits do not repeat in cages, and sum to the number in the top left. The unmarked cage sums to a prime number.
Thank you Nebula for brainstorming with me, and thank you so so much Ambrose and DarthParadox for the testing feedback!
Solution code: row 5 followed by row 7 (no spaces)

Not sure what happened with this one. I could not get through it without bifurcating.

Very linear solve path. Easy, but not a beginner puzzle.
