So Symmetry Area is just Fillomino with regions having 180-degree rotational symmetry?

In the Meandering Words example, R3C4 can be unshaded with the solution still unique? (So I can understand a region without shaded cell from the example.)

You are right in both questions. Regarding Meandering Words, some regions do not contain a shaded cell in the actual test. This means you can start the word from any cell in that region.

A very nice test. Puzzles were nice in difficulty, and especially nice in aesthetics and solving path; I enjoyed every minute of it. Some puzzles, thanks to their genres (read: Symmetry Area, Compass, Curve Data, Angle Loop for example), are much more solvable using intuition, making educated guesses instead of using deductions and theorems. Others are solvable using deduction with a very clean solving path, most notably Max Arrow Castle Wall 1; first attempt by intuition didn't lead anywhere, and second attempt by logic immediately led to the solution (with a few mistakes because there were 3 minutes left).

I've been trying to compile a list of favorite puzzles in this test, but I would mention a majority of the puzzles this way, so that's perhaps enough to say that the whole test was a very pleasant experience. But a special mention to Araf 2, anyway; that's an absolutely gorgeous puzzle, with givens that form a perfect pattern, that when I saw it I thought "wow, this can have a unique solution?" (It does.)

The only puzzle that I didn't solve was Max Arrow Castle Wall 2, which I didn't have time to attempt anyway; I should revisit it.

Really nice test, and I'm glad to see that volume 4 is being worked on! :-) I much prefer the ones that can be solved completely logically, rather than the ones with rubbers symbols, but all the puzzles were good quality anyway!
The grid lines/ lattice points on the New Tren and the first Curve Data didn't print for me (although bizarrely they did on the second Curve Data), did anyone else have that problem? I had to draw them in myself, which I think meant I submitted the 2nd Angle Loop about 1 second after time, which is a bit annoying! But a fun 2 hours anyway.

In most likelihood, this happens when you print directly from the browser. See this post for details. You might want to re-print the pdf after saving the file on your machine.

I'm sure you're right, thanks for the info, I'll try this next time. Just weird that it's not happened before.

An excellent set of puzzles. My thanks to the authors/organizers. I will also highly recommend the books to anyone who has not checked them out before.

An expectedly brilliant test. I love the books, the contest matched their quality. Thank you!

It's hard to choose favourites; somehow I always tend towards the ones that gave me most trouble. That's the Symmetry Area here: I couldn't solve either of those until revisiting them later, kept not seeing ways that things could resolve. And once you've figured out 11/19, the 8 doesn't work! Then I'll vote for Angle Loop anytime because the type is so good, as were the puzzles.

Other than that, the harder Meandering Words seemed easy, but I still broke it. It's hard to find errors in those. And somewhat annoyingly I fixed an error in Summon 2 first in one entry code line, then in the other.

I was a bit apprehensive going into this for two reasons. 1) I haven't managed to solve a single medium+ Angle Loop till now. 2) I am really bad at intuition/guessing. Considering that, the test went fine except for two puzzles. One of them is that Symmetry Area puzzle which was beautiful to look at until I had to attack it with around 10 erasings (mainly because I didn't want to get to the Angle Loop) in multiple re-visits across the test duration. I'm probably just missing something simple and doing silly things repeatedly. I managed to solve the easier Angle Loop which is a big achievement in itself, and I still can't get the bigger one to work. If not for my shortcomings in these two puzzles I'd have a really nice result.

One of the best contests of recent times. Very innovative and very logical. based more on logical solving capacity rather than on speed. I liked it a lot, in spite of spending an awful lot of time on the first symmetry area (I managed to solve it only after the end) and still can't figure out how to sort the bigger brother. Very elegant also the second angle loop. Thanks to the authors

As expected, the last Angle Loop broke me up for the last 10-15 minutes. It's a type that really doesn't suit me. I took a while afterwards to get it. I enjoyed all puzzles without a little eraser as the other ones caused some unnecessary problems. Not a bad performance overall though.

Solutions booklet uploaded.

It also has a listing of which author created which puzzles and original version of Angle Loop (2), which is more challenging than the one that appeared in the contest.

Congratulations to Robert for winning this one, he is way ahead of Bram (2nd) and James (3rd). While I personally don't own the book, I have seen the very impressive stuff. They are of very high quality, and the contest puzzles certainly matched to them. Thanks very much to the authors.

I'm yet to solve all the puzzles (especially Symmetric Area and Angle Loop), but my favourites so far have been Araf, Sunglasses and Graffiti Snake.

Not so important statistics - While Japan has the highest number of participants in this test, there is none from Japan in top 10. That is first time in any LMI puzzle test. I suppose the only way to keep them out of the top is ask them to author tests :)

Wow! No wonder Prasanna keeps asking when will Japan host the WPC :-)

Ahhhaaaa cool :D
