Logic Masters Deutschland e.V.

I loved watching the recent videos of Simon logic through some of FryTheGuy's pure killer sudoku. I made this puzzle and worked through the test slowly using the same sort of logic. But when I posted it and PulverizingPancake ripped through it in about 6 minutes I realized that I was daft. I went back and finished it with much easier logic in a much shorter time. I still really liked the logic that ended up coming out!

I have since created a puzzle Effective Field Theory (currently at 99% approval :D) which illustrates the original logic I had intended for this puzzle! Anyways, enjoy the easier puzzle! Oh also you can take a guess at why it is called "Not Quite Nice" :P

Rules:

Normal sudoku rules apply.

In cages, digits must sum to the total in the upper lefthand corner. Digits may not repeat in cages.
