Location: Indonesia | Great puzzles indeed. The puzzles feel reasonable (also I now know I'm not particularly good in Galaxies). I feel the exploratory rules for Galaxies is a bit stretching it though. Black and white circles are good ideas, but gray circles just sound like throwing the symmetry part of Galaxies away. I have no particular comments, although I feel Tetromino should also have a puzzle or two without givens.
Also, for some reason I blazed through the first six Tetromino puzzles in 11 minutes (plus two stupid mistakes on the first puzzle), and the last two in 17 minutes.  |

Location: United States | Excellent job, Serkan. I particularly enjoyed SG # 6, which I thought was quite clever. Thanks for the contest!

Location: Germany | Great puzzles!
However, I think I have an indication if my answer is right or wrong before I really submit it. Is this indicated? (The red border of the cell vanishes if my answer has the correct length of the entry string before I hit the button.) |

The red border vanishes when the sum of digits that you enter is equal to the size the grid (excluding black cells in Tetrominoes). It does not check for correctness of the answer.
For example, in Spiral Galaxy 1 - which is a 6X6 puzzle, if you enter 123 or 321 or 1122 or any set of digits summing to 6 the red border will vanish. We use this to check and alert if the answer is not formatted properly. Additionally, there is no penalty on answers which are not formatted correctly.
Hope that clarifies. |

Location: France | I agree with most other posters -- really great puzzles, but on Galaxies figuring out the white/grey/black rule and checking on the given example took forever. (I should probably just have tried to solve #7 with the rule I guessed instead of wasting time trying it out on the example, but I really didn't have faith that I had guessed right). |

Location: India | Thanks serkan, really beautiful puzzles.
Especially SG 5 and 6, Exploratory of Tetrominoes.
But unfortunately a bad test for me in Spiral Galaxies, I did continuously mistakes in all of them and at the end was confused to figure out rules for exploratory part and time got over. :(
After struggling little and fixing the rules it just took a minute each to solve each puzzle. :)

Location: India | Thanks Serkan for excellent puzzles.
I enjoyed both tests, I felt that Tetrominoes is easier than Spiral Galaxies.
I figured the rules for Spiral Galaxies exploratory part in just 1 min but due to stress I convinced myself that I got the rules wrong and slept :D
Regards,
Ravi |

Location: United States | How do I give up? The last two spiral galaxy puzzles are impossible to me; I am baffled by the example and I would just like to find out the rules. But the clock never runs out. Is there any way to forfeit? Seems rather difficult for a "beginner" contest. |

Location: India | i don't think you can do that, just leave it like that and when test ends it will stop.
But i would like to suggest you that try thinking in different ways, i also got stuck there but once figure it out its very easy :)
Just fix some rules what you think from given example and then try to solve, if you are not feeling its unique then try to extend some rules. :)

Location: United States | I can't read the post because I can't solve the last two puzzles. I've been staring at the example quite some time at different sittings. I can't come up with any rule sets that would give unique solutions. Very frustrating. I guess I'll just wait. |

Location: United States | In case anyone else has this problem--maintain your printer! In the experimental spiral galaxy puzzles, my black circles and grey circles were all sort of...greyish-black and indistinguishable. I use a cheap laser printer and the toner is running low. This made figuring out the rules impossible without explanation. Thank you Swaroop for the PM. I looked at the original pdf file and indeed, there are three different colors of circles not two. Time to go to the office supply store. |

Location: Germany | Hi, I could not figure out the rules for Exploratory Galaxy, which would lead to a unique solution. Could someone please explain to me? (Please real explanation, not only a hint, since I am already very frustrated with them. ;-) ) Before them, it took me only little time for the other six puzzles (at least for me), so I hoped to finish once in time, but then got stuck and ended frustrated. However, I was pleased with my tetromino results (even when not in time). Greetings, Nola |

So what was the rule in exploratory galaxies? I'm still stumped! |

Location: Japan | I spent 90min. of Spiral Galaxies Exploratory.
At first, I found regions with a gray point had ONE extra cell.
It is my regret that I tried match-making subsequently...
Even though they may not be suited for Beginners' contests, they are nice surprising puzzles themselves.

Location: Germany | I am also interested in the rules for Exploratory Spiral Galaxies.
@chaotik_iak: With your rules, the example has many solutions. For example, make the black and white regions as small as possible (each only 1 or two cells) and then you still have many ways to make grey regions. |

You can't make a white region 1/2 cells because that'd make it a rectangle. I think a white region would have to be a minimum of 4 cells (S tetromino) to follow the non-rectangle rule. |
