Country : South Korea | Joo M.Y posted @ 2021-03-31 8:06 AM Two questions for IB.
1. (Page 3) How many pages in Puzzle booklet?
2. (Puzzle 19-20 & Solutions) Max Spiral Galaxies: Is there any areas that are no dots or asymmetric? I think rules should be modified. |

Sorry about that. Rules are correct. There is a typo in the solution. The center dot should not have the left and right edges, it will be corrected in the next version. |

Country : India | kheti posted @ 2021-03-31 6:26 PM Hi,
For the Max Spiral galaxies, I came up with a solution that is different from the one on the IB. The circles in first and second rows are in a region with 3 cells each (one with the circle and one to the left and right). The circles in the 3rd and 4th row are in a region of only 1 cell containing that circle. All the remaining cells are in one region.
I am not sure if I am missing some rule and my solution is wrong because of that. Can someone please check?
Thanks,
nikhil |

Hi Kheti,
As the rule of spiral galaxy says, the region must be 180 degree symmetrical at the central circle point. i.e. If you take a region to the left side of a circle and you rotate by 180 degree, that should be the shape on the right side of a circle.
Whereas in your case thats not the case with the 5th row circle.
Here are some more sample examples - if it helps - https://git.io/JY2fg |

Country : India | Instruction Booklet updated
A new version of the Instruction booklet is available now.
Changes:
1. Pages of PB added (10)
2. Ordering of Fillominos changed (originally, 2nd puzzle was 12x12 and 3rd was 10x10. They are swapped, mainly to allow better editing of the booklet. They both have same points so nothing changes there)
3. Max Spiral Galaxies solution fixed.
Notes: We have kept the grid sizes of Fillomino and Double Choco sections slightly larger than the remaining sections. The rationale is that solvers may want to input numbers in the cells in these two puzzles, so it may be helpful on that front. In the penpa tabs as well for the competition puzzles, these two sections are tabbed to Edge-x in Composite, Line Normal and Number Normal, while other sections are just tabbed to Edge-x and Line Normal. The Puzzle booklet will be uploaded closer to the contest.

I am new to Penpa and was looking for a way to enter a number and draw an edge without having to switch between the two repeatedly, mainly for Filomino.
Is there a way to do that?
Thanks,

Currently there is no hybrid mode. But I hope you are aware of Tab feature. Pressing Tab allows you to quickly switch between Number and Edge. |

Country : United States | Wow, pretty difficult round! The Fillominos in particular seemed quite tricky (especially Fillo 1; I didn't expect to need a maximality argument for a 4 point puzzle). Solid puzzles though; I'll get around to the ones I didn't do someday :) |

Yes the solutions will be posted after the contest is over, but can take a while sometimes.
But this is restricted forum, so only who have completed the test can see these messages. So feel free to share here and we can help you figure out, whats missing in your solve if you dont wanna wait till the solutions are posted. |

Country : India | harmeet posted @ 2021-04-06 9:22 AM Thanks Swaroop for the delightful puzzles. My performance was below par. I got stuck with Fillo-1 & 2 at the beginning and got too late to pull back.
Nevertheless, the puzzles were thoroughly enjoyable. My favorites were Double Choco-3 and CombiBlock-3. |

Country : India | kheti posted @ 2021-04-06 1:48 PM Had fun solving these puzzles. The practice links and videos provided were very helpful. I practiced a lot and was pretty confident with filomino, shasigane, spiral galaxies and combi blocks and had decided to attempt these ones first. but as it turned out, I got stuck in the filominoes at the very start and wasted a lot of time there. Headed straight to shasigane and spiral galaxies and got them out of the way and then their Max versions. didn't expect to get stuck in combi block but I had very little time left when I got to it and so made a mistake in hurry. Could not get to the compass puzzles at all.
First time, I tried solving on Penpa. Was fun. |

Country : India | vopani posted @ 2021-04-06 3:07 PM Fantastic set of puzzles but extremely hard for PR. Could have been more enjoyable otherwise.
No particular favourites since most were high quality but generally liked the Combi-Block and Double Choco sets.
Thanks Swaroop!
