This is one of the most interesting variations of sudoku.
I enjoy solving these as they really test our logic skills.
I like them too, but I saw a little error on the first puzzle while solving it : the sum "12" concerning the region 9, line 7, should be an "11".
Nice and interesting blog !
Thanks a lot Ours Brun.
Error corrected :)
