Swaroop, in "NEWS"... For W-E, it need not necessarily be in the same row. In a specific region, if you are to place W-E, just make sure W is on the left hand-side and E on the right hand-side. It may or may not be in the same row. Similarly, if you see R2C4 and R3C5, N-S they are not placed in the same column.

I hope that answers your doubt.

Will the puzzles in the Final be exactly as shown in the Puzzle Types booklet, or will there also be variations of those mentioned?
Also, will there be only one puzzle per type, or a range of different sizes/variations?

Puzzle types will be exactly same. No more variations of even those mentioned.
In Round1 and Round2, there will be 1 puzzle from each type.
In Round3, there will be 2 puzzles from each type, one easy and one not-so

We'll publish an Information Booklet which will specify all these and the points distribution. It will take few days.

ABC Connection: Do all cells have to be used, or can some cells remain empty?

Paint-By-Number: Are the clues in the same order as seen from the given direction?

ABC Connection - You don't need to know if all cells have to be used to solve the puzzle

Paint-By-Number - Yes, clues are in order. Will change the instruction.

I had the same question for Anglers - Do all the cells have to be used or some may remain empty?

Is the answer same? ;)

For Rd 2 , the grid sizes are given in IB , can the grid size be shared for atleast the easy puzzles in Rd 3 and Rd 1 puzzles

The reason it is specified for Round2 is because I had to explain the partial points. Otherwise I wouldn't have mentioned that.

I can do that for Round1/3, but will it be really useful for you in planning / making a strategy, I'll do that. let me know.

Oh wait... may be I can't.
Many participants don't read forum, and it will be unfair to publish something about the puzzles here.
Sorry.

As such, if we publish the grid sizes beforehand, it will probably be first of its kind.

Since, i am new to puzzles, wanted to pick and choose which to concentrate on , like points grid size also indicate the complexity of a puzzle,
The grid sizes /range in some cases are surely useful, frameless sudoku, different sums, where combinations are needed
Also if posting in forum is a concern, updated IB is as an option ,open to other view points,

I must be sleeping when I wrote that we can't publish here. Obviously, as you said, we can update the IB

Utkaarsh, let me emphasize that the grid size will not reveal anything about puzzle complexity. As a sample, if I say the Frameless sudoku is 9X9, it doesn't signify anything about its complexity. It is only points that tell you more about difficulty.

For players who are new to puzzles, it is important to form a strategy to solve the types you are more comfortable with, irrespective of the grid size or points.

Come on Swaroop, it is a standard puzzle, with standard instructions. I've no idea why you are confused.

Hey everyone. Today on The Griddle I posted a new puzzle that may serve as good practice for the masyu-fence puzzle:

Shotgun Slitherlink

In this variation there's one additional twist: all the numeric clues consist of a 2 directly to the left of a 3, to form several instances of "23" throughout the grid. Every place that a 23 can legally be placed in the grid, the clues are given.

I also have additional masyu-fence puzzles (that I call "shotgun slitherlink") on my site which you can find here.

Happy puzzling!

Any particular reason puzzles of Round 2 are 20x20? I understand the concept is big grids, but was 20 chosen as a random round figure or does it have any significance? Just for trivia sake...
