But in the IB there is NOT written, that all possible locations of pairs are marked, so I think, that the puzzle is correct.
You are right. All possible locations of pairs are not marked. (There are several other places where A/B/C/D could have been marked)

Sorry for bothering you, I was just wondering what is the use of one single C in the whole grid?
Unless the instructions mean that 'if a 5 is used for pair D, it can't be used for pair C'. But that is not how I read the instructions; I interpreted it as 'if 56 is usded for pair D, the combination 56 can't be used for C. But 15 is possible for C, or 26.
So maybe I interpret the instructions not correct.

Hi Richard, this is correct interpretation. If D represents 56(or 65), C cannot be 56. C can however be 15 or 26 (or 34).

You have answered that yourself. If you determine that D is 56(or 65), C can never be 56. It does not matter how many times C is present in the grid. It could be once or more than once.

Hope that rules in the pdf are clear and they state the same thing.

It will be open entire Monday (GMT time), like other LMI monthly tests.

What does it mean that one of the Given 3x3 boxes is a magic square. Every 9 boxes are given... or does it mean that in the magic square box there has to be at least one given?

It's just to point out that only the marked 3x3 boxes count and not for example R2C4-R2C6-R4C6-R4C4. If they were to only say, somewhere in the grid there is a magic square, then this square could also be legal.

Maybe the word "outlined" should be there instead of "given"

To answer a question that was asked on http://sudokuvariante.forumactif.com, although I am quite sure of the answer: on this same puzzle, is it allowed that two or more regions each form a magic square? Also, is it allowed to find a magic square somewhere else in the grid, as far as the initial constraint is fulfilled?

Thank you.

At least one 3X3 outlined box is a magic square. Once the initial constraint is fulfilled, there are no restrictions.

Yes, online solving will be enabled.
However, please note that for some sudokus you might need external marking (e.g. Coded Pairs). You cannot do those kind of markings with online solving.

May I ask how we will need to do external marking? Since the sudoku type in question has all necessary markings already given to us in the puzzle.

What I meant was :
In coded pair, you might want to write A = 23 somewhere. If you are solving on paper, taking these notes are obviously easy, but there is no facility to note such things in in online solving.
Similarly you might want to draw a line in Linked Classics between the duplicates rows across the grids.

I have problem with Puzzle "Coded Pair".
In letters C and B, number 1 is common. I want to know that in different letters, all the pair numbers should be different or one them can be equal like the example?
i.e. you mean that only pairs "should not be equal" and if one number in the pair become equal, it is possible.

As replied in above post, 2 letters can have 1 common digit. But both the digits can not be same for 2 letters.

If letter D represents 56(or 65), letter C cannot be 56. Letter C can however be 15 or 26 (or 34) or whatever else.

Linking with WPF Sudoku GP registration


Here is how you can link you LMI registration and WPF Grand Prix registration (http://www.worldpuzzle.org/sudokugp/).

When you login in the submission page, you will get a pop up window as shown below.



3 options are listed. Choose one of the options and click on Save
Option 1 ) You can specify your email id for WPF registration. (By default your registered email address with LMI is shown. Edit it as needed.)
Option 2 ) You can specify your Nick name for WPF registration. (By default your username at LMI is shown. Edit it as needed.)
Option 3 ) Choose this option if you have not registered at WPF. In that case, we will keep showing the pop up every time you visit the submission page.

Online Solving Enabled

We have now enabled online solving of all the examples. Check the submission page for details.

As noted earlier, the flash online solving will only allow you to mark / unmark 1-9 on the grids. There is no feature to mark anything else.
For Braille Sudoku, the left grid is disabled, and you can solve only on the right grid.

Based on previous LMI tests, we think most players will solve on paper and not use the online solving interface. However, if you are one of those who plan to use online solving, you must practice solving as many examples as you can using the online interface. And if you are already familiar with the flash interface, you should still check it out because the layout of the sudokus is different (and hopefully more friendly) than previous tests.

Hello
I will be on holiday during the competition and if I want to participate I have to solve it online because I am not able to print the sudokus. Can anybody give me some hints for the online solving? How do you erase one number of the pencil marks?
