Country : India | Regarding the Navigation variant -
For 9 cells, Compass will have to be on the cell itself right? So we shall have to write the digit over it for that cell.
Also, for the Bird variant, which sum belongs to which group will have to be determined during the solve right? And I assume numbers can repeat in the bird groups, since one of the sums for 3 cells is 25 and another is 5. |

As I understand the IB, I would say yes, and yes.
I am planning to be very careful about two things : repetition/non repetition in the diagonals, since puzzles are not grouped according to this (however almost ); and on a personal plan, I will have to slow myself on the "Little Odd Even Diagonal Killer" since the association of parity and colors you made is quite the opposite of what naturally comes to my mind - I see even digits as round and green or blue, and odd ones square-shaped... This promises to be fun!
I just noted the 180' timing; how many puzzles of each type are we to expect ? |

I'm not certain, but I think its unlikely. Classics vs Innovatives didn't have online solving, and this test has some innovative variants with actual birds and fishes on it so I doubt it will. |

I guess you are right; 3 hours is 10.800 seconds and for 200 points it should mean 0,019 points per second, which relates to 0,03 points bonus per second. But: let's wait for confirmation... |

It should be clear because you see the points for every puzzle between the puzzle and the headline in light grey - even in the IB. Maybe this grey is too light.
14 - Little Regular Killer
22 - Irregular Navigation Killer
23 - Little Irregular Killer
56 - Little Diagonal Bild Killer
41 - Little Odd Even Diagonal Killer
20 - Non Consecutive Little Odd Fish Killer
24 - Dots Killer

3 hours?!
Yes, it is three hours.
Primarily I planned to enable four hours of time because I wanted to give the chance to most of you to finish all puzzles. These sudokus are really not easy to solve and my experience from creating puzzles for dozens of contests is that the results spread the more the more difficult the puzzles are in average.
I believe only the very very best in the world (if participating ) will be able to overleap 300 points by finishing within two hours.

Having been stuck during more than 30 minutes in an official competition on a little killer (having found only 7 digits ) created by Stefan Heine should perhaps scare me, but I look forward to this uncommon test.

Well, the point of the IB, as the name suggests, is only to instruct. As long as you understand the rules it's done its job. If you want to practice Killer Sudoku, we had a Killer Variations test earlier. http://logicmastersindia.com/lmitests/?test=M201204S (obviously, not with the same variants, but you'll get more familiar with Killer anyway ) Edited by prasanna16391 2012-08-23 10:42 PM

Thank you!
Some of the contest puzzles took me more than one week of work. Another reason is that I want to give at least 100% to create the best I achieve from the variant setting. To produce an other 9x9 set for the IB would result puzzles that could not meet my claim. |

It is true! :- ) But in 6x6 it is not possible (I think ) to create an non consecutive with not repeating numbers on the main diagonals. That is why I wrote "In the example, digits on both main diagonals may be repeated" as the last sentence in the IB. |

Definitely impossible indeed, since 6x6 nonconsecutive sudokus have to obey one of these two patterns :

Country : India | Great. I'll start off by saying, I enjoyed the test as far as solving goes. As for the 3 hour format, well I personally think this would've been great in a Marathon-like format. I solved 6 of the grids in 70 minutes before starting the Non Cons- Odd Fish variant, and I got stuck on that one for the remaining 100+ minutes. In between(after some 60 minutes of trying), I decided to submit the other 6, and then take a break. Got back in 5 minutes, and then completed it with 8 minutes to spare. Totally, 104 minutes.
I'm not saying it was that difficult, I got back and solved it with a fresh mind later and it is just as "easy" as the others. Its just that, out of the 7, I did 6 pretty fast and I feel like thats all been wasted due to the 7th one. I see janoslaw had a similar experience, and maybe Kota too in the middle, I don't know. If this were a single-Sudoku-submit format like Puzzle Marathon, Sylvain and Hideaki would still be at the top, but at least the gap won't be so huge for those of us who just blundered in one puzzle, as we'd still get the bonus for the rest at least. A really difficult set does that, you miss one thing and you end up staring for long spaces of time.
All in all, probably my favorite set of Killer variants ever(which is saying a lot since Killer's my favorite Sudoku variant anyway), but I'm not happy with my performance, and also don't feel like I got full value for it, even though I finished an LMI test for the first time. |

Country : India | @kishy72, Thanks for your feedback. I have no hesitation in agreeing that this is very tough test if you are a beginner or have limited experience with Sudokus.
At the same time, every test offers different experience and I'm glad that you enjoyed the ride.

Country : India | Now coming to the difficulty of the grids.......infact non consecutive fish is very difficult compared to the points allotted to it.....atleast i could not crack it till now....i am not able to get the right start....even birds i have to try again....i wasted full 1hour in these two puzzles and achieved nothing....
But getting continuous 3 hrs spare time is really difficult atleast for me.....
But overall a wonderful test. |

I didn't see this till after the test but, its quite easy. Sum up all the given diagonals, and since the main diagonal is 45, all the rest of them should add up to 360. This gives you, for example, R1C1 + R9C9 = 4, because all the other diagonal clues above and below the grid add up to 356. I'm hoping you already figured out that R1C1 is 1/4 (because the 8 clue is either 3-5 or 2-6, which eliminates all those numbers for R1C1) |

Country : India | A wonderful test and such a new experience of different level of sudokus.
I started 1 by 1 and finished first 3 grids within 1hr and now 4grids were left with 2+ hrs to spare.
I then went to "little odd even diagonal" as this is my favourite one and comfortable over that and finished it well.
Then i started "little diagonal bird killer" i immediately figured out which bird has to what total, but then no inch ahead except 2-3 numbers in place.
Now almost 1.5 hrs were left and i then moved to" non consecutive" but stuck for 10-15 min and didnt get anything then i tried "dots killer" again nothing for 10-15 min. basically for almost 2 hrs i was stuck with these 3 grids breaking head to get atleast start at least. Just 5 min left i got dots killer but could not submit it on time i needed just 30 sec more to submit the answer. And "non consecutive" as prasanna said above i didnt think in that way and so was not getting the start. Now will try remaining ones. :)
Nice experience i would say. Thanks to LMI AND Stefan_Heine.
Regarding difficulty i would they were not hard but tricky. Well i am still learning new things so 4 is ok for me or 5(unofficially) :p

Country : France | Nice set of sudokus.
My favorite was the little odd even diagonal which has a regular level of difficulty during all the solving. Dots, Non consecutive and birds were more difficult to start but when you find the starting point there is no great difficulty to continue the grid.
For example, when I saw non consecutive, I thought that there was many numbers outside for a variant (non consevutive) which often didn't need many digits to start. That's why I immediately used the sum of diagonals to find L1C1 + L9C9 and L1C9 + L9C1. I think that it was the sudoku I need the least time to solve.

Country : France | Of course you are all wrong, since the hardest one was obviously the Dots Killer. I needed 30' to solve it, more than any other puzzle. But maybe that is because it had no solution. I am not kidding. When there are only two options and that both lead to contradictions, there is obviously a problem. And when, after 15', you realize you had missed a third option and that this one also proves impossible, there remains no doubt : there definitely is a problem.
And there was !
There really was a problem !
There was a big problem !
There was a huge problem named me and me needed 10 more minutes to understand that there was a fourth option - a perfectly valid one.
So, a total of 30' on this only puzzle; 64 on the other 6; 2 minutes to copy the codes, and today is not yet the day when I will say :

Country : France | Disappointment apart, this was a really good test, with some superb puzzles. All of them were nice, but a few were truly excellent. The "Bird" was of course tough but very interesting to solve. The "Odd Even" was perhaps my favorite; as Sylvain said, the puzzle was very homogeneous in its difficulty and the path was very pleasant to discover and follow. No big trouble for me on the "Fish", I did just as Sylvain and summed the diagonals; still, it was probably not the fastest one for me. The "Dots" was nice too; the best proof is that I liked it despite the big amount of time I wasted on it! Just a remark about the "Navigation" : if my memory doesn't abuse me, I did not use the two sums at the top of the grid; only the two at the bottom. They really did not seem of any help to me, so I guess I somehow deviated from the intended path.
Anyway - thanks a lot Stefan. I join Neeraj : it is obvious that you spent a lot of time on this set. Now take some deserved rest. |

Country : The Netherlands | Richard posted @ 2012-08-27 2:28 AM Little Killers are not really among my favorite ones. I think that has to do with the possible repetition of digits anlong the diagonals, and the 'unnatural' looking to (non-visible ) diagonals, instead of the more 'natural' rows, colums and blocks. Whenever possible, I skipped them. So far.
When I saw the IB this week I had two feelings.
1 ) It is a test from Stefan, who I know from past German Sudoku Championships, so I should give this test a try and
2 ) OK, I will have to step over my feelings towards little killers and practise a few.
So I did. I found a few older LK's, started practising and found a few tricks and thought of a few other possible tricks. I wrote them down and that was quite a good idea. Pretty helpful for some grids in the test.
Before the test I thougt the 41-pointer and the dots-killer were highest on my 'most wanted' list.
I decided, when I would finish these two puzzles within 75 minutes it would be wise to try to do the 56 pointer too.
But like others, I got stuck in it. The birds-values were easy determined, but after that progress didn't come, so I decided to finish the other grids first. The last 15 minutes I have been busy with it again, but without finishing it.
Now that I am typing this message, I feel I am tired of the marathon concentration.
But all in all I had a good evening, with 6 out of 7 grids solved.
I have one question about the planning of this test. LMI is encouraging unexperienced players to participate and is even organizing beginners' tests. And then one of the first real tests beginners can participate in, is this one with pretty tough puzzles. Is there a reason for this? I guess so... |

Thanks for the hint, now that I tried after the test, it went really quickly. During the test, I just didn't see any way to get started so I didn't even attempt it seriously...
All in all, a really nice test, what I did manage to do was really fun to solve, though I'm still a bit shaky with little killers. I liked having lots of time to solve, as I could just keep working on a grid without feeling like I'm wasting the time if I don't make quick progress all the time.
The non-little killers I mostly just breezed through, with a bit of a hiccup on Navigation. Bird I ended up brute-forcing by bifurcating heavily: The eventual solution was the second try from the third try at the top. Still, it was very well constructed, as the solving progressed very nicely from each try and the contradictions did come up. I was a bit disappointed that it was so easy to figure out which bird gives which sum, though.
Apart from the Fish, I also missed out on the Odd Even. I hadn't thought about the solving techniques properly and ended up having to discover most of them during the solving. When I finally got my act together on that, it wasn't too difficult to solve, but by then I'd already run out of time by several minutes. |

Well the monthly tests are difficult. While we do encourage players who do well in the Beginners' test to participate in these, it is a big step from being successful at that level to being one of the top solvers at this level. The Beginners' Contest deals with the basics and fundamentals. I believe, if an inexperienced player clears those the person will at least be better equipped to deal with these harder monthly tests, even if not Time-solving them.
The Beginners' tests will keep going every month, and such a good set of grids should not be passed over because of that, so I feel, no better time than now ; ) Of course its a tad bit too difficult since we've not yet introduced Killer/LK into the Beginners' Contests, but we can't really change up schedules and what not because of that and we just hope the Beginners who had too much of a difficulty with this one will understand that. If any of them do have a doubt with any grid, they can definitely ask over here. |

Country : France | All dots were given, but they only applied to vertically adjacent consecutive digits.
Always read very carefully the instructions! |

Country : Austria | euklid posted @ 2012-08-28 1:15 AM I think I am alone with the problem that I had:
I have completely overlooked the "non-consecutive" constraint at the little odd fish killer! :-)
Without this constraint the puzzle was pretty unsolvable (of course :-) although I had counted the diagonals and knew the corner numbers pretty fast...
Could have finished this test but I am happy with my result anyways. |

Country : India | Killer Shootout is now over. Congratulations to Nikola, Sylvain and Hideaki for taking the top 3 spots. Sylvain took 2.5 minutes to check his answers which probably cost what-could-have-been his first LMI title.
22 players finished all 7 puzzles in the allocated 3 hours. Many others submitted 6 puzzles (there are 20 scores of 144, being separated by submission times)
Thanks Stefan for the Sudoku set, and we hope to hear from you about your experience as well.

So I did. I found a few older LK's, started practising and found a few tricks and thought of a few other possible tricks. I wrote them down and that was quite a good idea. Pretty helpful for some grids in the test.
Some of the possible techniques for the Little Irregular Killer that I had written down were not necessary to use in the test.
Since it is possible to have a nice co-operation between chaos areas and diagonals I have made two puzzles for the puzzle portal Germany in which those techniques have to be applied. The easier version solves much faster if you apply the technique, the harder one is very tough if you don’t apply the technique.
Have fun!

Country : Germany | Thank you all very much for participating at my first LMI Test! It was very exciting to watch what you do. I hope you all liked the puzzles and if there is anything in general, that I could have done better - please tell me so that I can learn from this.
Congratulations to Nikola, Sylvain and Hideaki - you were sooo fast - incredible!
I hope to see many of you in Croatia.
Thank you!

I can only advise you to have a look at them; both are very nice, the harder one being truly excellent (and quite tough even with the right technique ). |
