I was aware that players might try to solve the Maze using "Fill Colour". But the image was created such that Fill Colour won't work. I used 3 different software to test that (mspaint, Paint.Net, PicPick) and Fill Colour simply won't work with the maze image. Did you find it otherwise? If yes, using which software?

Well, it was done intentionally (even putting dots instead of digits). Otherwise, both the puzzles should have been only 5 points each.

This year's IPC seems to be very successful as it has selected 4 names who are arguably the Top four in the country. With the experience and talent in this team, we can expect extremely good results this year.

I obviously did not use this during the test
But I just created an image in ms paint, closed the entry points and filled with colour.

Bad testing on my part. Luckily, it was not a whole lot of points. Thank you for bringing it up.

I solved this maze during printing the PB. It was the first page, so I had it still on the screen and it was pretty easy to solve it just by eyes. However, the idea by Rakesh is very smart although it is slower than honest solving.

As others have said, too few easy and standard puzzles. Online National Championships and WPC qualifications are the competitions that are most likely to attract new/nonregular solvers, and they should not be frustrated.

Also I did not prepare, and so I stumbeled across some unusually wordings in the puzzle booklet during solving.

For example in Easy as ABC, it is not said, that each letter has to be used in each row/column. Actually, the wording is different from the instruction booklet, which is a no-go for me.

And in Kakuro it is only stated, that digits can not repeat in words with a clue. Experienced solvers might see such wording as a "hint" for a twist in the puzzle, which could cost much time.

I agree ideally Hitori and Mastermind makes up more in the newspaper quotient, but I think accessibility beyond newspapers can be defined with two points -
1. Easy to understand rules.
2. Types with many examples available if one is willing to search.
Even assuming there were no dedicated practice sets, Nurikabe, Tapa, Tents, Battleships, Star Battle, Easy as ABC, Hidden Words fall under point 2. Corridors, MCQs, fall under 1. Sudoku, Kakuro, Slitherlink are newspaper puzzles. I'm only leaving Black and White Loop away from category 1, because there's a few tricks implied by the rules that aren't obvious.

So accessibility-wise, the "classic" half of IPC 2013 was very much accessible, at least in my opinion. I also don't think we should stray away from the Classic + Variant formula, because that is in fact suited for beginners, as they mainly need to look at 13 sets of rule-sets with a few tweaks (overwhelming in itself, when the newspaper puzzles can only cover up to 5 distinct types at most), instead of 26 different rule-sets. It is definitely more accessible than the USPC/UKPC I think, at least for an Indian. Puzzle backgrounds may differ and the USPC/UKPC may be more accessible to participants of their respective countries.

I'll say again that, more than accessibility the main problem is the fact that the classic puzzles themselves had twists and were a step above what newcomers were prepared for. The Sudoku was a notch higher than newspaper difficulty, the Kakuro had a few clueless cells, the Hidden words didn't have words, the Easy As ABC was huge, the Slitherlink was a complete twist. These being the first puzzles that any Indian newcomer would attempt (this much I'm pretty certain of), and having a bit more than usual would be the main turn-off.

The problem with Atril (the Evince fork for MATE) persists with the IB as well. However, the problem seems to be localised to specific pages.
IB: 6, 8, 11, 12, 13
PB: 6, 10, 11, 13
I thought I had located the culprit in the form of the labeled row- and column- pointing arrows used for keys. Alas, after looking at the IB, this seems to hold very roughly, so something else must be going on.

How did you come to know about Indian Puzzle Championship?	I am a regular visitor at LMI forum.
Did the Instructions Booklet (IB) provide enough information about participating in IPC?	Yes, mostly.
Did you understand the puzzle rules, examples and answer keys from the IB?	I understood all of them.
Did you find enough easy puzzles to solve during the championship?	Yes, some of them were easy. I would have liked more easy puzzles.
After your experience in IPC, are you going to participate in future championshiops or contests at LMI?	May be

Sudoku : The difficulty of the sudoku was higher than newspapers, but should not players be tested little more than what they solve everyday? And this was a sudoku, that still didn't need anything other than hiddens/singles. Although it had fewer clues compared to newspaper ones, it still had a wide solving path.
Kakuro : I didn't anticipate the problem that beginners might face. Otherwise I might have asked Serkan to add all the clues.
Hidden Words : Not sure if I agree here. A search is a search, whether letters or symbols. Agreed that, with letters it is easy, but the solving methods are pretty much same.
Slitherlink : Didn't we already have a classic Slitherlink in page 2?
Easy As ABC : It was huge, but it was easy. But yes, someone looking at this first time, they may not want to attempt it.

For a newcomer, the Sudoku having fewer givens is in itself intimidating. So is a Hidden Words having symbols. Note that a newcomer is someone who has probably never solved a word search with symbols, but has maybe solved a few word searches with letters. Slitherlink, I hope you're joking with that :P Easy As ABC as well, like Sudoku, intimidates with appearance itself.

The main point I'm trying to make here is that, the IB "features" (whether intentional or not) these puzzles as the ones that are familiar or easy to think about. A newcomer will go in thinking what they know from the newspapers is good enough to get some points, and then get intimidated at the starting steps itself. Thats never good. Make the common types really easy (easy by the definition of a newcomer and not an experienced puzzler), so that they can actually translate what they already know into some amount of points, instead of having to advance their thinking from the start itself.

My opinion applies to the Turkish GP as well.
If we all cater newcomers then there's no room for "surprise" innovations.
But we must also consider what is fair game and what is too much of a stretch.

The Turkish GP's only flaw I find is with the rotation of the photo in Spy Sudoku.
A player shouldn't be asking "hmm.. maybe this flips" during the competition.
I don't see how changing fonts on the first 3 puzzles is an enough excuse for one to complain about the entire test.

With this year's IPC, the puzzles are fantastic. The symbol word search, unclued Kakuro, few-clues sudoku shouldn't be a problem as the
rules aren't that much deviated. Heck, you might as well criticize the 16-submarine battleships too then.
But when the rules do bend by far: for example having Strange as ABC, the instructions of Easy as ABC - it didn't happen, but it
illustrates what isn't fair.

I thought it was good to think on your feet, since it is required at the WPC.
Remind yourself that this test's goal is to select the best Indian team members, not making newcomers too comfortable.

The sudoku I think is actually ok, and the kakuro wasn't too bad neither. The Nurikabe on the other hand, especially for someone who is used to the Nikoli style, was awfully hard for 20 points. The slitherlink I think is ok in a twisted sort of way, since the point value and the geometry made it clear enough that I should skip. (and I would imagine it to do the same for new solvers as well) Coming from someone of my skill level at least, there's nothing more frustrating than diving into a problem that you think you can solve due to type/point value, but it turns out that you can't, or that it takes a large amount of time.

Thanks Rakesh, Prasanna and others for bringing up the point that the set was not really best for beginners. It took me a lot of time to understand why you are saying that, and now I realize that I was defining beginners differently. A beginner in my opinion is someone who has strong sense of logical reasoning with a desire to solve challenging problems (not necessarily the puzzles at IPC). I thought those are the kind of players who can take us forward in world puzzle map. That is the main reason for having puzzles with simpler instructions so that they don't feel uncomfortable with the rule itself. But here we are discussing about beginners who have exposure to puzzles, have solved newspaper puzzles (and might shy away if they see a 20-clue sudoku).

However, since the general feeling that it was tough for beginners - by either of the definitions, we will need to include easier puzzles in future IPCs.
