Wow, an 8-grids match makers ! Already with 6 grids it's not obvious.
We must "have eyes in front of holes" (translation of a french expression) ,
and above all be comfortable with the 8 types of grid.

Fred

I think the point is:

A single puzzle can be treated as, say, nonconsecutive or diagonal, with different solution. But there is only one way to solve 8 grids and that each rule correspond a single puzzle.

If a puzzle A can be treated as nonconsecutive AND diagonal and a puzzle B can be only treated as diagonal, the puzzle A has to be solved as a nonconsecutive !

Am I correct?

Fred

i got purifire's idea, "puzzle A 's solution is diagonal and also non-consecutive", it won't happen.
when you try to correspond one rule to one situations, for example: if r2c2=1, r1c4=1, then it can't be no knight step sudoku, or some advance logic method to make the form unique.
Fred have a good explanation for the rule, thank you!

Ok I get it, so each puzzle will follow only one constraint and if in my solution I get a diagonal and a non-consecutive, then obviously there is a mistake that I have made somewhere..... :)

I hope this clarifies Jason's question as well. :)

Adding my 2¢s -
There will be exactly one way in which the 8 instructions will fit in with the 8 grids. One needs to use the table in page 6 to keep track of all the eliminations.

In the Classic Relays, the transfer of digits from one puzzle to the next one can be in any order, right? (If R1C2 is shaded in both puzzles, it is NOT NECESSARY that they should have the same number, correct? But it should have one of the three numbers in the shaded cells of the first puzzle)?

Yes, that how it looks like from the IB.

Thats Correct Rohan... Elimination by sudoku rules has to be used to determine which number goes into which cell.... say a number 4 in R1C2 may or may not be in RiC2 of second puzzle depending how the clues are placed in puzzle 2. This is assuming that R1C2 is shaded in both puzzles :)

Announcement

We found that the grey cell marks and the dotted cell marks may not be distinguished clearly in paper print-outs
The authors have changed them to white circles and grey circles. Check the updated IB.

There are no other differences.

Announcement - About Sudoku#17

Sudoku# 17 is a twin sudoku (Classic + Irregular having same solution ) . However, it does not have any givens. After solving Puzzle 1 to 16, you have to copy 20 digits to Sudoku#17 and start solving.

Our online flash interface will not do the copying for you. If you are planning to solve online, copying these digits from other grids might not be efficient because lot of scrolling will be involved.

So, we are providing the grid for Sudoku#17 now itself. Click here to download
We think this will be very handy while copying the digits from other grids. Online solvers are suggested to keep a print out ready of this page.

[ This page will also be part of the puzzle booklet, so paper players don't have to do anything now. Of course, they can check out the grid and find some tricks :-)]



If you have any questions, please post here.

Can you check the jigsaw borders once...I think there is one mistake in the pdf (in the last row, most probably)

Notes for online solvers

There are 8 Matchmakers Sudokus.
It is not possible to show all the 8 Matchmakers in the submission site at one time because of computer screen size.
From Mock17 experience, we think it is becomes easier when you can see all the Sudokus together.
If that is the case with you, you may want to solve the matchmakers on paper.

please be specific... I can't see the problem.
Note that sometimes when Acrobat Reader is not at 100% zoom, it may not show some images perfectly. Try to zoom out and see.
But if that is the case, there won't be any problem while printing.

OK. Let me be specific...One jigsaw area has 10 cells and another has 8 cells.

Further note on Sudoku#17

There will be obviously 2 grids.
1) The flash system is not equipped to automatically copy digits from each other.
2) While submitting, submitting any of the grid is fine.

If some player submits both the grids, and non-zero digits don't match, he/she will get 0.

The grid for puzzle seventeen has numbers 1 to 20, which I assume will be the clues to be transferred. but will the same numbering be used in the actual puzzles too for transfer?

Ouchh... Disabled downloading of the file until the error is fixed.

As has been informed.... classic 8 and the matchmakers will have cells marked with numbers 1 to 20 which need to be transferred to puzzle 17 to solve it.

Is it possible to solve classic puzzles in relay without transfering digits?

I'm not sure if I understand your question properly.

Here is how it will work.

CR = Classic Relay

CR1 will have 4 cells with grey circles. CR2 will have 4 cells white circles.
After solving CR1, you need to transfer the digits in these 4 grey circles to the 4 white circles in CR2.


CR2 will have 4 cells with grey circles. CR3 will have 4 cells white circles.
After solving CR2, you need to transfer the digits in these 4 grey circles to the 4 white circles in CR3.


.
.
.
So on
.
.


CR7 will have 4 cells with grey circles. CR8 will have 4 cells white circles.
After solving CR7, you need to transfer the digits in these 4 grey circles to the 4 white circles in CR8.


CR8 will not have any grey circles.

Hope that clarifies.

If you don't transfer the digits from CR1 to CR2, you will find multiple solutions to CR2.

Thanks, this is all I need to know.

You can determine digits' position by logic, don't worry about this.
It's the first time we do this kind of relay, so they're easy to determine, eg: {1234} from previous puzzle, and in next puzzle the mark cell already have {123} in its peer cells, so this cell must be 4.
but, no all like this :) if you make the wrong place, you will find no solution for the puzzle, or if you haven't decide all marked cells, you will find multiple solution.

I went through the IB version 2 but could not find the points distribution. When is the points distribution expected to be announced?
