Location: Germany | 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. |

Location: 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. |

For Spiral galaxies 4/5... It is an exploratory type. I am not sure if it has been there earlier as part of any contest. You can get some idea from the example given. We shall try to create another example.

I want to be clear about the time period to take the test 'Regions' : Will it be possible to take it on 30th Nov or not ?
Yes. The contest will end at 23:59 GMT on 30th November, so you can take it anytime before that.

Location: 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. |
