A big thank you to Fred for posting a solution path for the Extra Regions Sudoku. Beautifully done and I must apologise for my earlier comments. I have also found a simple logical solution to Sundoku and a logical (but very difficult!) solution to the 0-8 Killer. As predicted, once the time pressure was off, my brain started to work a little better.
Hi David. I am glad you could finally solve the killer logically. The puzzle wasn't that hard if you managed to follow the intended path, but of course this path wasn't particularly easy to spot (well, the puzzle was worth 140pts...).
Time for a global look on the test.
Generally, puzzles were widely appreciated and this is always a major satisfaction, being the main goal of each and every author. More of that, some of them got some emphatic comments, in particular Mixed Sudoku from Laurent Pierre (the man who depicts himself as a "beginner author") ; we can only be satisfied of that and it fully rewards the work which has been done.
My own 0-8 Killer also got some very nice comments and this is a great reward. As I said to Serkan on saturday, this puzzle caused me some torment. My original idea was to simply create a basic killer with 20/3 areas but after several tries, I couldn't get a satisfying puzzle in terms of difficulty. Then came the idea of using a different set of digits, and the "0-8" set appeared to offer lots more possibilities to play with - in particular, the sum "3" now admitted 3 different combinations, including a 3-cells one.
A few more tries later, I obtained this puzzle on which I had a mitigated feeling, certainly due to the fact that my previous attempts (with 1-9 set) had been somewhat disastrous. So, I sent the puzzle to the other authors but I remained a bit hesitant, not totally sure if it was really good or if it was just "better than the ridiculous previous attempts".
Finally, Fred and friends told me there was no issue with this puzzle and encouraged me to keep it ; I hadn't given a look at it since its creation, so I came back to it, found the solving smoother than in my memories, and did breathe a big sigh of relief.
My two other puzzles were the Arrow Sudoku (clearly not an incredible one, but I had it created some time ago and it fitted well with the theme ; some not too bad steps to find if following the main path, though) and the Consecutive. Again, not a fantastic piece of a puzzle but I had some score to settle with consecutive puzzles and designing a themed one happened to be a good way to do it.
Unfortunately, there were a few issues due to color (but as Deb said, the use of color was an exception because of the spring theme, so it souldn't happen again) and to the fact that one or two puzzles were definitely hard to solve online. That's a pity but things rarely go as well as they were intended to, and I think that, despite of these, the balance remains positive.
The Alpha Frame and Double Sum both did something I dislike in sudoku contests (as I commented before in the Numerologidoku on the January test) of requiring extra conversion steps to get to the real data. You are absolutely right that not being able to replace the letters with fixed numbers (as paper solvers could do) is a disadvantage, so in my opinion the authors should have kept the PRINTEMPS theme but simply also printed P=16, R=18, I=9, ... along the rows and columns to save everyone from doing this extra(neous) step.
I agree. By the way, I also dislike these extra conversion steps but we thought that, by giving the alphabet table, every player would quickly replace letters with numbers and that it would be a "lesser issue". Unfortunately we omitted to take into consideration the fact that online solvers couldn't replace the letters with numbers ; if only we had thought about it, we would surely have adopted the solution you propose, or something very near.
I won't extent about WaterlooMathie's last post ; answers have already been given. Let's just say that problems are always far more obvious to spot once they have happened...
All in all, a big thank you to all the players who had a try on our puzzles. I truly hope that, amongst the various grids, everybody found some puzzle which fitted him/her.
