Great puzzles. I was a bit confused on the Delimited Kropki as the instruction book says "adjacent cells with no markings must not contain digits whose difference is one or whose ratio is 2. Take a look at the example in the instructions
--row 3 column 7 and 8 contain a 2 and a 4 -- but both cells are not marked.
--row 6 column 1 and 2 contain a 4 and a 5 -- but both cells are not marked.
--row 3 column 8 and 9 contain a 4 and a 3 -- but both cells are not marked.

The instructions booklet states 'Kropki rules are applied only for a pair of cells where the centers of cells are connected with a grey line.' In all of your examples, there is no grey line connecting the two cells, so kropki rules do not hold.

Hi,
I wrote down my notes from author's perspective regarding the Sudoku Round 4, incl. basic hints for 4 most valued puzzles. Posted here - http://sudokualogika.cz/node/2372.

I hope it can be useful for some players. But be careful it is written in Czech language. :-))
