In Little Killer, should main diagonals contain each digits from 1 to 9?

There are some differences between score table and points stated in the instruction for each puzzle. Which is correct?

In Multiple Killer, the cage number '1580' on R2C1 is probably wrong. '1680' seems right.

Yes Kota... The main diagonals contain digits 1 to 9.

Sorry About that Deu.

Updated IB has been uploaded. The typo errors for the Product Killer has been Corrected. The point distribution mismatch has been rectified. Additional Instruction on the two main diagonals in the Little Killer has also been updated.

Thanks.

I solved all examples.
5 is still alive: The rule'Digits cannot repeat inside a cage' is written. But, the example puzzle does not satisfy this rule.
Twin Killer: In below puzzle, the cage number in R5C6 13 is wrong. 9 is correct.

I don't know what will be the rules of the test puzzle (waiting for Rishi's answer), but here is a puzzle which satisfies the rule "digits cannot repeat inside a cage".

Here are 2 versions of the grid. Of course the "kid" version with digits 2 and 3 in row 2 can be solved by a 6-month baby. I made the second version just to preserve my reputation of creating hard grids.

I have modified the IB to reflect a 6x6 5 is still alive puzzle. The actual rule in the test will be that the digit cannot repeat inside a cage. The example puzzle earlier was from Five Fold test by Serkan where the digits can repeat. That was an oversight from my end.

Twin Killer Digit also has been corrected.

We can definitely have poll or I can simply put them up horizontally in the PB.

Putting them horizontally is definitely preferable, so lets not open a poll.
The only thing you need to take care of is that the grid size shouldn't be very small after you have 2 grids horizontally.
So, you need to have the page with Twin in "Landscape" orientation, while all other pages have to be in "Portrait" orientation. This can be done easily, if you are using Microsoft Word.

(Fred was using Open Office, so we decided not to experiment. We were not sure if all printers support this. We were also bit skeptical because lot of players had reported printing issues in Fred's previous test "Spring Test")


The twin puzzles in shapes and sizes and Diagonal Vision were both vertical. Why are we now saying horizontal is definitely preferable? Horizontal will mean I will have my arm over the right side puzzle when writing on the left side puzzle. I'd really prefer vertical positioning. It's how all Twin Sudoku puzzles I have ever done look.

Personnaly, I prefer horizontal presentation of twin grids. That being said, I don't think that it makes a lot of difference for me, and it'll not bother me if the twins are presented vertically, as Richard and I made for the previous tests.
The points are:
*I think for online players grids will be presented horizontally (because of monitor's size). The question is: Should it be perfectly the same between online and paper players? or knowing that it's not the same, each player can chose the way he solve this particularly grid (if he prefer horizontally, he can solve it online)?
*The second question I've asked to myself was the printing issues. With different paper orientations on the pdf file, knowing the vagaries of the computer science: with a huge amount of different printers and drivers and a lot of different "pdf reader" software, I feared that someone could have a printing issue due to this fact. That's why we chose a vertical presentation of the twins for the last test (Technically, it's not difficult to have different page orientation with OpenOffice).

Since it doesn't take much to compile/print an extra page, I guess we can just keep both presentations in the PDF and let the player choose?

Of course this will mostly mean in my case that I'll never be sure of which one to choose and end up leaving it entirely...

Personnally I prefer only one page and use scissors to put the grids as I want ( vertically, horizontally, diagonally .....)

I believe that I am not the only person who use pencil marks during solving. The cells and grids seem to be too small and I am not able to write down all I want. For now, I rewrote the training puzzles, but it took me 15 minutes, so in such case I will be not interesting in taking part this weekend. Is it possible to make the grids larger and sharper?
Thanks a lot.

The actual test puzzle will be bigger with 1 puzzle in every page. Since this was the IB, I have put 2 puzzles on each page.

This is a post to inform you all that there has been a change in the title of the test. People felt that the earlier title was bringing up images of an unsavoury event of the past. Our intention was not to hurt anyone's sentiments and after discussions with fellow solvers across the world, we decided to change the title.
Our focus and passions are all towards puzzles and we intend to keep it that way.

Appreciate the inputs of Tom C, David Millar and Jason Z on this.

Another "5 still alive" with the rule "Digits cannot repeat inside a cage" for your training (quite different style than the first one):

It seems like 8 and 3 are still alive too:

Hope it's not too far away from the original theme, but there's some specific logic which is the same, and I don't think there are many examples out there for this type.

Both puzzles were specialties, and inspired by the one of the fivefold sudoku test.
Sometimes a 'theme' can be a very simple digit...
The first one I made was for the 3rd anniversary of the puzzle portal in Germany, and the second was a bit too hard for the recent German sudoku championship.
Maybe they will help in preparation for this killer-test. The way to think yourself into the puzzle might be the same...

Hey guys I've seen the 0-8 sudoku before but haven't understood the variation - is the purpose simply to throw people off their usual killer sudoku rhythm? Can't you just add one digit per cell to each cage and treat it as a normal killer?

Looking forward to the test

Yes, and yes.

I don't think it is a variation either, just an attempt at a paradigm shift that is unfortunately more detrimental to online solvers than paper solvers who can "fix" the puzzle. Just be sure to convert back to 0-8 before submitting the answer.
