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: Canada | I guessed wrong on #7 in such a way that produced the right answer, and only realized that when I was trying to do #8...... |

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. |

(PS The Score link at the top of this page is referring to the 201304 test, not the 201403 test...) |

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. |

Cat Bonus is short for Category Bonus which is explained in the Instruction Booklet. There's some bug in the score page, and you are eligible for the bonus. We will look into it and rectify it as soon as possible. |

Location: Poland | I would be grateful if you could see my "cat bonus" as well - solved all the tetrominos in time, so probably should get the full score for that? Best - Bartek |

Location: United States | About Tetrominoes #5
I have these rows: K: LLTIIIIOO (alternatively TZZIIIIOO) L: ITTTIZZIL M: LLLTTTLL
Which seemed to have an answer of 2142 (or 1242) 131211 332
But neither answer was accepted. Tried a couple of times to see if I fat-fingered them.
Resolved MANY times but always came up with this answer.
Where have I gone wrong? |
