Killers are among my favorite sudokus, so I did enjoy all six puzzles that I was able to solve in two hours. Those were also exactly the ones I had planned to try, so my mission was accomplished! All in all it turned out to be my best relative performance so far, so I am even happier with this result.

Thanks for the puzzles and hard work!

Im Glad you enjoyed them Richard. You are welcome.

Thanks for the great set! I was sorry that I mentioned some mistakes in the past instruction.
I did my best performance, but I was disappointed at being beaten by janoslaw by more than 10 minutes.
I'm going to play at the next test better than now.

Kota, You don't have to be sorry about the mistakes in the IB. It just goes to show how valuable the information in the IB is and how correct it has to be. Its a good sign that you look into the IB deeply.

Jan M blew the test no doubt but your performance was no small feat either. congrats again.

I liked most puzzles. I just found it a bit strange that the untouch Killer didn't need the extra constraint. When I solved it afterwards I didn't use the untouch at all. I am not sure how the opening was supposed to work, but the way I did it, I had no use for the the untouch rule and after you get it going, thinking about the untouch rule would just be distracting when you can just work the cages.
