Deb and Prasanna looked at my puzzles and gave many suggestions on how to make puzzles that fit into competitions, because many of them are completely symmetrical (solving one half was enough to complete the puzzle).


Just to clarify, I solved the puzzles, Prasanna just gave suggestions about the format based on my feedback.

Structure for future LMI Beginners' Puzzle Contests

Basic :

There will be 2 rounds of 40 minutes each. Each round will contain 8 puzzles of a distinct type, meaning the contest as a whole will cover 2 types.

Each round's puzzles will be divided into four categories, with 2 puzzles per category :
1. Introductory - These will strictly be extremely basic puzzles, of trivial sizes.
2. Intermediate - The sizes may vary but logically these must be trivial. (10x10 can be maximum size unless it is a puzzle type with different dimensional characteristics e.g. Skyscrapers would have a 6x6 cap.)
3. Challenging - Here we reach the typical Monthly test lower pointer level. A few techniques/patterns can be used, and the sizes may vary. (10x10 cap on size unless it is a puzzle type with different dimensional characteristics e.g. Skyscrapers would have a 9x9 cap).
4. Exploratory - This is defined as a twisted version of the rules of the puzzle type. The twist must provide a different perspective while not deviating much logically.

There will be bonuses separately available for finishing each of these categories. These bonuses are not fixed and will be computed based on each contest's puzzle points distribution.

Notes :

In case Explorative versions of a type are not possible, there will be a puzzle each added to the Intermediate and Challenging categories.
The size cap clarifications will be given at the time of communicating the types to someone interested in authoring.

Features :

As noted in the opening post, Instant Grading and Extended Time features will be used in Beginners' Puzzle Contests.
Please note that the category bonuses will not be applicable during extended time. All puzzles submitted in extended time will count for 50% of their assigned points with no bonuses
There will also be an overall bonus of 1 point per minute saved for completing all puzzles within normal time.

Beginners and Seasoners :

There will be Beginner and Seasoner categorization here as in Beginners' Sudoku Contests. However, it is difficult to put a system in place to promote players to Seasoners based directly on their Beginners' performances. A player will be a Seasoner by default if they meet one of the below criteria -
1. Those who have attained, at any point, an LMI Puzzle rating of 500+.
2. Those who have achieved a rank of 25 or better in an LMI monthly Puzzle test.
3. In case of a string of performances deemed exceptional by the organizers (this is pretty free-flowing as of now. We'll try to work up a system later).

Looks great! I still don't think I understand the "exploratory" thing though -- I thought those were going to be slight variants and would come with their own instructions, but saw no such instructions in the IB.

Are they just normal puzzles (or variations on the usual layout that will surprise us a bit but don't actually require any new instructions) this time around?

Thanks,
Denis

I will say this much - the given instructions are enough to understand the exploratory part. If it were necessary to add new ones, we would have. But Exploratory can also be a different mode of presentation of the puzzle. Experienced players may not find these surprising, but we thought it would be a nice additive for beginners, to get used to the twists and surprises that accompany puzzle solving, without stepping out of the normal form too much.

Wow. Very nice set of puzzles, but the first star battle variation was deliciously evil. I had to re-read the rule three times to figure it out. Otherwise, as expected I'm really not a slitherlink specialist...

An interesting initiative. and one with a few tweaks is what I'd like to see form the basis of the WPF's puzzle GP. I look forward to giving this a go.

However one thing that really bothers me is the fact you are lumping two separate types into one contest. I can appreciate you want to introduce as many new types as possible, but I'm not sure the final scores can have any real meaning. Why not have two contests running simultaneously, but independently, and have two sets of winners? That way you would have a clear slitherlink winner, and a clear star battle winner, which seems far more meaningful to me.

This is a good point. We will separate the score pages, but we are yet to work on that. The priority was to get the contest up and running this week.

I enjoyed the puzzles very much, but to be honest, the Star Battle part had a little bit too much "gimmicks" for a beginner contest.

I've started slitherlink, my timer started and I can see the space to submit the answers. But I am not able to see the problems. Where can I find the puzzles??

Good that you found it out.

Players who are participating for the first time need to note that the puzzles are available in a password protected pdf file, which they must download before starting the round (see green arrows in the image below).
The password for the pdf will be displayed once you start the round, and you can open the pdf file. (see red arrows in the image below)





@rvarun
No special rules. But you anyway have figured them out by now.

Thanks PS for the test.That was great fun!Wish more of this sort tests come more often.I got stuck for a long time in the 3rd (Intermediate)puzzle which i felt had as much sting in it as the more challenging ones.In the end it boiled down to one crucial deduction that had eluded me for a long time in the 3rd Intermediate.

I have one minor suggestion that i would like to give for this test.Wouldn't it better if the test is spread out on more papers than just 2?Of course it looks nice and compact now with just 2 A4s for star Battle.I haven't solved slitherlink yet.But i don't mind spending a couple more papers for such a nice test.For example the spread could have been like this:2 exploratory on a new page vertically aligned(so Total 3 )or 2 intermediate on a seperate page and 2 exploratory on a seperate page(Total 4).Though that would put just 2 introductory on one page it looks oK to me.
(I spend a lot of papers for less useful reasons anyway!)So at the max just 2 more papers but the experience would be even more better I feel.

My favourites in this Star Battle test were the 6th and the 8th puzzle with the latter occupying the top spot.I have solved just 1 or 2 of these 'irregular' type star battle puzzles in the past and this one served as a good practice .Overall a great set of puzzles for beginners like me!!!

Star Battle : very pleasant ! I lost too much time on the 3rd pb to have a good score, and I was quite destabilised by the 7th. After the 40 minutes have passed, everything appears clear !
Concerning scores, I suppose we have to wait to have the real scores : I'm pointed with 44 points ?!? I finished just the 1-2-3-4 within 40 minutes, and all the others later.
So I could understand 16 pts (3+3+5+5) or 29 (3+3+bonus 6 +5+5+ bonus 7) or 46 (3+3+bonus 6 +5+5+ bonus 7 + 9/2 + 9/2 + 8/2 + 8/2), but not 44...

Yeah, there's a few things to fix on the score page as it is now. They will be fixed. We're a bit short on time right now. Festival time in India

Nice set of puzzles.

The time could have been 90 minutes. 40 minutes seems less especially for beginners.

Nice puzzles.

As a presentational issue, although the instruction booklet gives a consistent set of rules for the exploratory star battles, most solvers understand there to be the same number of stars per region as there is for rows/columns - especially when this is the case for the first 6 puzzles. As an experienced puzzle solver myself, I had to scratch my head for 30 seconds on #7 to make sure i was ok on the rules. From that respect, the "2 *" label was a little misleading, and perhaps something like "2 * row/column, 3* region" would have been fairer.

Nice set of puzzles. Finally completed the Slitherlink after an internediate break of more than two hours. It was tough to concentrate on long time. Hope I rectify this by more practice.
