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?

Another notice for players: Please make a table for variants part before the test, or print the one in extra page.

!!! Best of luck to everyone !!!

Hard !!!

Oops Fred.... now you are scaring me

Tough set.
The puzzles were really nice, especially since I like Match-Makers puzzles.
I liked the concept of transfering digits without knowing directly which one goes where, it makes the relay concept more complete :-)

Looking forward to results and feedback of others.

Rohan, thanks for your comments. Hopefully that will un-scare Rishi.

Thanks for feedback.
To Fred: i think you can do better.
I hope someone could make Niulang and Zhinv meeting. :-)

Hard..... but beautiful !

And yes I think I could do better, I've done mistakes !

Fred

Im bad at matchmakers and I dont think anything Rohan said unscares me

You are forgetting that now I am a part time Sudokist... I am not even sure I will be able to take 2 hrs away at a stretch

It can never be worse. First did a mistake in Puzzle No 7 and then carried forward the digits to spoil Puzzle No. 8.
In short screwed...........

Great set of puzzles. Awfully difficult.
I'm glad I was able to participate this time around. Can't always have 2 hours straight to do puzzles, but when I do, it's always FUN!
Everyone at LogicMastersIndia should be commended. Your mock tests and other puzzle sets are typically high quality stuff. Thanks!

Wow, very nice puzzles. Didn't finish in time but afterwards I have let them meet ;)

Really nice puzzles.
Matchmaker part was beautiful.

Overall a nice set of sudokus. The objective was to make Niulang and Zhinv meet, however, both got lost somewhere. The matchmaking logic was beautiful, and unfolded very logically.

The small point classics were really beautiful and I had never enjoyed solving classic puzzles so much before.
I struggled on the higher point ones, maybe there is something that Im missing in solving the more difficult ones.

Matchmaker was awesome. It was not too difficult to identify which sudoku goes where. The puzzles were high quality too, especially the anti knight sudoku.
I broke the touchy sudoku, else would have had a few more points :(

It might have been better if there were more time to solve, or maybe two separate sections, so that people do not have to choose between which section to solve.

Amazing set of puzzles.... thoroughly enjoyed them.... Im not sure how amit and Rohan found match makers easy :D

I wasted nearly 20 mins trying to resolve them... :)

Had a great time solving them nevertheless...

Although my performance was below my abilities, I would not have been able to make Niulang and Zhinv meeting. I'll be surprised if more than 2 people can achieve this goal.

P.S.: I like surprises

I agree with you Fred.
