thanks for the link guys - for the example puzzles.

Fred, do you have a link for all puzzles in Chen Cen Cup?

Yes, but it's in Chinese: http://www.sudokufans.org/forums/index.php?s=6f82f2002843e02895f319...

Here is list of grids:

1-3 classic sudoku
4 no touch sudoku
5 diagonal-consecutive sudoku
6 the greater sudoku: The small number within two cells stands for the larger of that two.
7 calculate 6 sudoku: Operators of all the neighbors which can get 6 are shown.
8 blackout sudoku
9 arrow sudoku
10 twins sudoku
11 multiplication sudoku
12 pencil marks sudoku

I call them no tens, and I made mine first :p

I have a doubt all of a sudden: When I create my grid I thought I had never seen another one, but when I looked at yours, I'm pretty sure I've already solved grid N°55 !

Perhaps it's just Alzheimer who knocks on the door !!!

About Greater sudoku -

We found that the existing image does not fit well with the Flash system we have. So we recreated the image with minor formatting changes. Rules / points remain unchanged.
This is same example as what Fred has shared.

Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9.
The small digit between two cells stands for the larger of the two.

I apologize for not having designed examples for this set of questions, which include new variants. I have another problem of greater sudoku and I'll post it here for exercise.

11 Sequence sudoku - In other words - will the total number of grey-cells be exactly equal to the total number of digits used (to fill-up; underlined) in the original sequence?? (which means no overlaps) or it could be greater than the total number of digits used of the original sequence ?? (which means there could be overlaps)

The number of total digits of original sequence is greater than the number of gray cells. And, there should NOT be overlaps.
Just like that example.

Just went through the IB.
Some of the variations look to be very interesting.
Loved the concept for Blackout Sum Sudoku and Incomplete Killer.
Looking forward to the test.

Now let me put in my 2 cents about the puzzles :)

The puzzles were true to their name of a " HOT POT "

They reminded me of a complete 5 course meal...

The sudokus at the start were like the appetizers, simple and giving you confidence to take in more...

Then came the basic variants which were like the starters whetting the appetite....

Then came the new variants which are real fun and like the main course..

Finally I saved the best for last, incomplete killer, which was the perfect dessert to this hot pot.

@Rishi
Your description of the puzzles is sounding very inviting.
But will wait patiently till tonight when I will get 2 hours at a stretch to solve.

Very glad that you love this HOT POT :)
In fact, you are really a gastronomist.

Very nice and neat puzzles. I enjoyed solving the 'easy' Classics, much to my satisfaction.
Variants were very good. I liked BlackoutSum Sudoku the best :-)

The test was excellent as expected! :)

I really liked the classics. though didnt expect them to be that easy. BlackoutSum Sudoku was really good, I liked the Greater Sudoku also.

Some really great puzzles in the test.
Had a really smooth run in the classics.

Loved the incomplete killer and the kind of logic involved to solve it.
Could not get around to solve the blackout sum sudoku and will give it a shot at leisure.

Thanks for creating such a wonderful set.
