Normal sudoku rules apply.
Killer sudoku rules apply:
In the killer cages (cages bordered with a dashed line), the number in the upper left corner indicates the respective sum of all digits in this cage. Digits may not repeat in the killer cages.
This is a revised version of the puzzle I posted earlier today in which I had made a small error (apparently 7+5 != 13) which resulted in multiple solutions.
I only had to change the two cages in the first box, so the majority of the solve should be the same.
I test-solved this one twice, so hopefully this one works, my apologies for those who got stuck on the broken puzzle earlier.
Most of my previous puzzles have a "fun" ruleset. With this one I wanted to practice on something more standard.
If you liked this one, why not try my other killer sudoku, it needs just a few more succesful solves to gain its difficulty rating and score: murder on the orient express - killer sudoku
Solution code: row 6 followed by row 9

Nice fix-up! Glad to see not too much needed changing, I started from the beginning just to be sure and enjoyed the puzzle once again!

I (hopefully) fixed the puzzle to have one unique solution.
