Location: The Netherlands | Hmmm,
Seven example puzzles, adding up to 200 points. It's not clear how the points distribution over the contest puzzles will be. Unless the contest will only contain 7 puzzles... But that is very unlikely, looking to the 3 hours time for the test. Can organizers say anything about this? Or do we have to make choices on what puzzles to try and what not only after seeing the real PB? |

Confirmation will come when Deb/Author/Test-Solver is online, but yes it is mostly 7 difficult puzzles. |

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... |

I am proud and happy to present to you my first LMI Sudoku Test!
I will try to answer all of your questions step by step.
First notification:
Because the UK Puzzle Championship and the US Puzzle Championship is also scheduled to happen this weekend the "Killer Sudoku Shoot Out" is open for 96 hours, instead for 72 hours (including a Tuesday).
yours

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.
Three times yes - all assumptions are correct!

...how many puzzles of each type are we to expect ?
Only one puzzle of each type - it is seven sudokus for the whole test!

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
----------------------------
200 Killer Points

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.

Location: Switzerland | It looks like this tournament will contain harder sudokus than my test diagonal vision  .
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.

Otherwise, it would just be an extraregions sudoku (compass covers 9 cells)  |

Is there online solving?
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. |

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)

Location: France | And yes, there is a particular reason to this fact, which is quite obvious : preparing one set of 9x9 puzzles is already lots of work; preparing two, even if the examples are of a simpler conception, means of course that much more work. |

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 :
