Instead of "a black circle may not be on the intersection of four cells", use "regions may not be 2x2 squares".
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 | One clarification on the answer keys: If parts of the same region come more than once in the answer key, they need to be mentioned separately in the answer key. |

I found this to be very easy. Some of the puzzles are simply too guessable. |

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. |

Country : India | Yes you are correct, it becomes clear when approached from left. But the problem was I took it 5 by default , don't know what made me. Anyways waiting for others performances. :)

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. |
