Country : India | Thank you for pointing this out. Since it doesn't affect the key we thought the fairest option is to announce it on the submission page and leave it as is. Apologies for the inconvenience (also to future solvers). |

Puzzle 18 has 2 solutions. The issue does not affect the key, so the puzzle will stay unchanged.

Country : Canada | In the Dosun-Fuwari Park example in the IB, would it be a valid solution if the balloons in the solution in cells B2:E2 (Excel notation) were instead moved to B2:B5? |

In that case the balloon shares an edge with the ball piece in B6 which is not allowed. |

Sorry, I removed part of your post because I was experimenting with the restrict-thread thing (It wasn't working properly ) |

Country : India | Wonderfully balanced set of puzzles. Had a lot of fun. Glad I could finish it just on time but disappointed that I wasted lots of time imagining the rotations and reflections of "5" shape.
Enjoyed thoroughly. Thanks Priyam and Prasanna, testers and LMI :)
I liked all the high-pointers. |

Country : United States | Uh...the link at the top is contradictory at the moment. It says this goes until May 5th, but also says it ends within 24 hours right now. I think that ought to be resolved. |

Country : ITALY | GaS posted @ 2021-05-02 5:13 PM Hi All, just one "patological" note for Dosun-Fuwari Park puzzle.
Reading the rules, if I have an Iron-ball shaped as the U pentominoes, I could have, in theory, two such iron-ball linked togheter "floating" supporting each other with no other "support" below them. The same for two U-shaped baloons.
OO
OXX
OOX
XX
I guess that, in the "spirit" of the rules, it will be not allowed, but in theory it could be a valid solution with the actual rules ... :-)
Obviously, other shape could have the same effects.

That's a very interesting point. I'm thankful the shapes in both puzzles don't have this situation. If this puzzle type is reused it is definitely a valid clarification to add to the ruleset (or just let be and consider while constructing the puzzle ) |

Country : India | rajeshk posted @ 2021-05-04 6:41 PM I have doubt regarding Dosun-Fuwari Park as below
Do we need only one of the given shapes for the regions? or different regions can contain different shapes. Given example uses only one shape but the instruction does not prohibit different regions from using the different shapes. Please clarify this.

Different regions can have different shapes within the allowances below. In the example, you could have had the 2x2 ball replacing the trimino ball in any region if it didn't violate other rules. |

I liked the Minesweeper puzzles and Star Battle puzzles the most. I was stuck in Statue Park and Myopia Shapes was I was unable to rotate the shapes correctly :).
Overall very good PR test.

Country : India | vjain9 posted @ 2021-05-06 10:43 AM Yes Prasanna..... Lot many queries in DF Park ! Is the linked ball piece considered as one unit and a part suspended if another is supported , acceptable ? IE is a 3 ball unit is placed horizontally on 1 black square and 2 balls hanging , allowed ?
Only the available units have to be used and single units cant be used ?
A unit has to be used within a highlighted region only ( This is now amply clear - YES ) |

What you are saying as "3 ball unit" is actually just "1 ball". The shape in its entirety is a ball.
Only available shapes may be used. |
