Country : Germany | rob posted @ 2015-11-22 6:44 AM Just to confirm: It is a consequence of the rules of 4/5 Spiral Galaxies that there can not be a 2x2 square.
The example is uniquely solvable without that rule. |

Yes. There cannot be a 2x2 square. as circles are not allowed at intersection of four cells. |

Country : Indonesia | Spiral Galaxies 4/5's rules aren't very elegant...
Instead of "each region has exactly one circle that is the point of symmetry" and "not all black circles are given" (which are somewhat contradictory), use "if a region contains a black circle then it is the point of symmetry".
Instead of "a black circle may not be on the intersection of four cells", use "regions may not be 2x2 squares". |

Thanks for the suggestions. We will include these suggestions also while updating the points table in the IB. |

2x2 squares are not the only regions that have the point of symmetry on the intersection of four cells... |

We are talking of regions with 4 or 5 cells only. |

Yes. The contest will end at 23:59 GMT on 30th November, so you can take it anytime before that.

Country : India | Thanks for awesome set of puzzles. It were really nice, especially Spiral Galaxies.
Happy to finish the set, after disappointing performances in last 2 rounds. Could have done lot better.
I finished All puzzles except 5 Galaxies in 40 min. Then took another 23 minutes(I know I am slow in galaxies,, so kept for last) to complete this 5 until I broke Spiral Galaxies 4/5. I had to again and again and end up no solution at center. Later I finally realized my mistake, somehow in the bottom right corner where there are 2 horizontal I's of size 4 and 1 of size 4. I was drawing it as 2 of size 5 and 1 of size 4, don't know why. But none the less finally realized and completed just in time.
Looking forward next round Snakes. :) |

Looking forward next round Snakes. :) Thanks Swaroop. Yes. The Spiral Galaxies were a bit trickier compared to the rest of the puzzles. Good to see you completed the set, which I expected as well.
In the last puzzle, in the bottom right corner, one 'I' pentomino and one 'I' tetromino were obvious. The third one could be a 5 or a 4 length 'I'. If you make it 5 there is no solution in the center area. But I think this becomes clear once you proceed from the left area. |

BTW, why did the author make a new rule "There cannot be a circle at the intersection of four cells." in Spiral Galaxies 4/5?
In original Spiral, I think it has no problem that there appear such circles.
In fact, The puzzle in this set has multiple solutions if it permits such circles... |

A nice set of puzzles. I liked the Spiral Galaxies set as well, but the Fillomino set was also nice; since I like Fillomino puzzles in general, I go with that choice. Particular favorites: Spiral Galaxies 4, Shikaku 4, No-Rectangles Fillomino, Spiral Galaxies 4/5. I find Shikaku 4 to be overvalued (I did it in 2 minutes ), and Spiral Galaxies 4/5 as well (6 minutes, compared to Spiral Glaxies 4 which took 14 minutes ). Maybe that's just because I suck at Spiral Galaxies, and Spiral Galaxies 4/5 is closer to object placement (only 5 possible shapes ) than region division. |

Thanks Kota. Yes. The original spiral galaxies has no restriction but, even in the spiral galaxies set of four puzzles, I did not include any such circles. And, as you said, the spiral 4/5 may have multiple solutions if we allow the 2x2 shapes.
The main reason for me to exclude the 2x2 shapes was that, for some reason, I found it difficult to determine uniqueness with them as a possibility. Also, since this was an exploratory version, I took the liberty to set the rules as per my comfort level. I hope it did turn out ok in the end. |

Thanks Ivan!
(1 ) The first three shikakus are straight forward. Shikaku 4 is also not difficult, but there are a couple of points where you need to take the right decision. Some of the testers also spent fair amount of time on this puzzle. But, if you get the right start, it flows smoothly.
(2 ) Most of the solvers are definitely taking more time on Spiral Galaxies 4/5. So, as of now, it seems to be rightly valued. The main reason is that after the initial givens, the way to proceed is not explicitly obvious. A decision needs to be made - top/left/bottom. Time is spent there. Also, this one should be little unfamiliar, so I expect people would again read the rules while solving.
(3 ) I would say you took a bit more time on Spiral Galaxies 4 (and Spiral Galaxies 3 as well ). It is supposed to be easier than spiral galaxies 4/5. |

Neat set. Hard to choose between Fillomino and Spiral Galaxies. Loved both.
This is one of my better performances in puzzle tests, I was able to race through the puzzles without an error. Few of my guesses directly hit the solution, probably because they are very intuitive.
Thanks Rakesh, really enjoyed solving puzzles authored by you. I think its been a long time :- )

How did you open the pdf file and print?
Directly from browser (like Chrome )?
OR
Saved the pdf file on your laptop/desktop and then open/print?

That was fun, thank you! Most of this was just quickly drawing in the solution. I guessed on the large Yin Yang, and the 4/5 galaxies was an "exploratory" solve. I could see that one being quite frustrating for players who breeze through everything and then get stuck... Regarding the puzzle quality: I felt that for a lot of the types, the puzzles didn't really cover the available logic as well as on previous instances, but that may just be a consequence of the puzzles being so easy that they didn't all force a solving path. |

I faced the exact same problem when I tried to print it directly which made me waste about 5 mins before I could solve the first Yin Yang.The problem can be avoided if you save it as a pdf file and then print it out .Atleast,this was the remedy in my case. |

Country : India | @peluri, It seems you have faced this kind problems earlier ( #post 16955 ) also.
I strongly feel the resolution is same as what kishy72 mentions. You should first save the file on your laptop/desktop, then double click to open and print from there.
The inbuilt browser in Google chrome is known to mess up pdf rendering among other things, you will find several links on how to disable the pdf viewer in chrome. |

Very nicely balanced round, after the hard Numbers round and very hard Evergreens.
Indeed.This was exactly my first afterthought upon completion of the test.Seldom do I choose "Just Right" in the "What was your opinion of the distribution of easy/hard puzzles?" category.Mostly,my choice would be too many hard puzzles .Not that I have anything in particular against the test but just that the puzzles would be too hard, subjectively speaking.But this test was an exception.It ideally reflected the 50% easy, 40% medium, 10% hard concept .In my opinion, the Spiral Gal. accounted for the hard part ,Fillominoes and Yin yang taking the medium and the rest being easy.
On my personal experience,with about 30 mins left on the clock for 3 puzzles ,spiral Gal. (6 ,10 and 14 ), I was looking at a possible finish .But as luck would have it,I got stuck on spiral Galaxies 3 which according to me is the hardest of the set .Just kept going wrong repeatedly, until I finally completed it.I cursed myself for not attempting the 14 pointer being intimidated by its points .I completed it after the test in precisely 7 mins 53s.Ah!
Also, I noticed that I have taken a serious liking to Shikaku puzzles .I was surprised seeing my time that I completed all shikakus in a span of 7 mins. Too bad ,there is no PR round dedicated only to shikakus. : )
To conclude,this was one of those tests where I had a sense of satisfaction having completed 20/22 puzzles which I rarely get in a puzzle test with more half the puzzles left uncompleted.
Thanks Rakesh for a wonderful set!
Btw,refreshing to see Deb give a feedback or is it a new user with the ID debmohanty ? :-p :-p |

Its not been a long time since this is my first puzzle test as an author. I think the 'region' puzzles in general work faster with intuitive solving. |

No. Neat as in, it was crisp, good and overall a nice pleasant solve. Puzzles were not 'extraordinarily fantastic', but it is an excellent set for a PR round. I liked it better than Numbers, Evergreens and my own, Classics.
Yes, its your first puzzle test, but I meant in general... long after Prime Exotica and mock-tests!

Country : India | @Puzlifouk, @rob: I agree that a high number of puzzles were on the easier side. Personally, I take the positive that most solvers will get a chance to try out all puzzles in the set, which rarely happens.
@wgryciuk: I didn't expect anyone would select "too many hard puzzles" but you have. Can you please share your thoughts about the hard puzzles? |

I could see that one being quite frustrating for players who breeze through everything and then get stuck...
I've since looked at these puzzles again: I missed reasonable steps on both puzzles. That fourth Yin-Yang did a good job showing some different logic. And the 4/5 is fair (for me, it felt quite lucky that I got it out in reasonable time ).
By the way I had more trouble with Spiral Galaxies 3 than 4. |

Thanks Rakesh, this test was very fun. A few of the puzzles were too easy to guess at (e.g. the fillominos which had very few hidden polyominoes ), but overall the test was nicely done. Spiral galaxy 3 was very tough though, I think I spent 15-20 minutes on that one alone. |

One particularly generous puzzle was the 10 point Shikaku. And the "easy" Spiral Galaxies didn't seem to be that easy. In fact, I solved them in the order 1, 4, 3, 2 despite starting them in the right order. But, to be fair, I'm not desperately good at Spiral Galaxies. Overall though, fun test - the first one I've ever finished! |

"I have a different complaint" - the grid lines were not visible on the paper when I printed the puzzles, for Fillomino (incl variant ) and Shikaku puzzles. Probably a matter of too thin grid lines or so. Used a Win 7 laptop and some Canon InkJet - I do not typically have similar problems elsewhere. Thanks. |

Very nice set of puzzles. The spiral galaxies were very nice and I felt were a bit undervalued as compared to some of the other sets like Shikaku. Many puzzles had a very intuitive solve and it would have been nice to have a couple of puzzles in which the most intuitive option would not lead to the correct solution. But having said that this set was a big relief after the previous rounds : ) |

Thanks for your feedback!
The 1 and 2 pointers were mostly giveaways. However I still saw some solvers spend a lot of time on YY1 and FL1.
I had kept the more familiar variations - Fillomino and Shikaku - easy (maybe, too easy ). AD4 and YY4 were also in the same category. The objective was that everyone should be able to complete these sets and sample the other variants also. The spiral galaxies caused a few problems for most solvers, as expected. Although I did not expect SG3 to cause more problems than SG4, it did.
Another aspect which I maintained is that points for every variation (leaving the exploratory ones aside ) would be almost equal. This is probably one reason SH4 got 10 (generous ) points. It worked out well in the end, as most solvers were able to get Fillomino, Shikaku, Area Division and Yin Yang out of the way and still had enough time to grapple with the Spiral Galaxies and the two puzzles in the end. Some of them succeeded, others did not. But a majority of the participants were able to "sample" all variations.
Yes. It would have been nice to have a couple of puzzles in which the most intuitive option would not lead to the correct solution. And, I could have had more hidden polyominoes in the Fillomino. Valid points both. Also, at one point, I had considered increasing the difficulty level in FL3 and SH3. But ultimately decided against it.
Finally, glad to see the word 'fun' included in most of the feedback. That aspect is very important. And, it always feels good to complete a test with bonus! |

Thanks for the extension!
Also didn't have grid lines for Shikaku, ABC and Fillomino - forum said I should save and print - will remember that next time.
Personal experience: spiral galaxy 4 being easier than 3,
shikaku 4 way too easy for 10 points,
spiral 4/5 regions took me 100 seconds to actually solve (and not guess) - for 14(!) points!?
stuck on spiral galaxy 2 and 3 forever...
Need to do more tentai shows next time round ;)

Country : India | Due to major rains and flood in Chennai, Rakesh is facing internet issues, so I'm posting a summary on his behalf.
Congrats to Endo, Hideaki and Robert for the top-3 international spots and fantastic performances. Congrats to Rohan, Amit, Prasanna and Swaroop for the top Indians who completed the set.
Spiral Galaxies were definitely the most challenging of the sets, while most of the players breezed through Fillomino and Area Division. SG3 seems under-valued since it was the least submitted puzzle with only 6 points, and Shikaku4 seems little over-valued since a lot of people solved it. But overall, it was a well balanced test, where majority of people enjoyed, a lot more players finished and certainly a refreshing change after the last two difficult PR rounds of Evergreens and Numbers.
Hope the see the weather in Chennai improve soon and some of Rakesh's own feedback and thoughts. |

Country : India | Sorry for the delayed reply.
Thanks Deb! Thanks to the test solvers Zoltan and Branko! Thanks to all 256 participants and everyone who provided feedback.
Spiral Galaxies was voted as the most liked set and I had the same opinion while creating this test. Based on the overall feedback, I found that many participants, even the more accomplished ones, have accepted that they are not too familiar with SG. I am satisfied with the broad puzzle categories that we came up with in this test. My personal favourites from this set were SG3, SG4, SG4/5 and NR Fillomino. So, we can say, I was a little biased towards SG in this test.
Really happy to see 16 Indians with 50+ score in this test. Special mention for Rohan, Amit and Jayant for their good performance in this test. And Ras-hmi and bapusp90 for trying too hard!
Based on the submission times of some of the top players in this test (EKBM, deu, rob, Takeya, uvo, Rohan ), I tried to calculate the point distribution, and the results are as below:
As already noted, the SG3 should have had about 11 points and the SH4 could have had 5 points. Other than that, the points distribution matches the outcome. This was known before the test but we did not want it to be SG-heavy test point-wise. So, even though the SGs were a little challenging, they had less points value per minute.
This was my first test as an author. I am happy with the constructive feeedback received and will ensure the future tests in PR and otherwise, would benefit from the same. It is difficult to have a test which appeals equally to beginners and seasoners. The attempt was there to balance the experience for all participants. I wanted the best Indian solver complete the test in 45-55 minutes and was able to meet this target. Also, happy to see some of the participants do well and finish a test for the first time. |

Maybe make harder Shikakus and easier SGs, then? |
