Country : Germany | I remember a discussion whether or not three pentominos can met at a point, but I can't find the particular puzzle right now. It might also be one of your "Pentominoschleifen" or one of Luigis puzzles. I also solved two of these, but I can't remember that I had problems with the description. However, as far as I remember, I found them much harder than other solvers difficulty rating intended. Maybe the ones I solved are unique even without it, and it makes them much easier to use this additional rule.
I think "There is no point where three or more pentominos met." is a short addition that makes everything clear. This also excludes the case of diagonally touching pentominos, because only two would violate the loop rule, and more is not allowed.

According to the instructions it is possible that two white cells in one domino add to a prime number. |

Country : United States | Ugh. Not pleased with my performance, but the puzzles were great. However, I did lose about 10 minutes on an error in the instructions for 12 (Spiral City). Instructions claim the numbers go from 1 to 32, but there are only 30 segments. My math on the two center rows just refused to work until I threw out the 31 and 32 segments. Probably could have figured out one or two other puzzles in the time, but it still would've been awful. :)
Regardless, thanks for the entertaining set! |

Country : France | auroux posted @ 2013-09-07 12:23 PM The puzzles were indeed really really good -- one of my favorite recent tests. But I had terrible luck with timing, finishing the Sudokakuro just 5 seconds too late (of course it'd have taken another 10 seconds to copy down the answer key). Sigh. |

One comment on the submission page: Is it possible to have the puzzle numbers (1-20) included as well as the names? It would be much faster to find the correct location to enter the answer, especially as some of the puzzles had similar names. |

A good test, but hard to prepare for. It was 16 unusual types, some with rather specific rules. The LMD practice material helped a little, but some of the LMD puzzles used subtly different rules from the test. Despite doing all of them, I still felt shaky going into the test. |

I am not aware of subtly different rules, maybe apart from the Filled Loop. I think I didn't use the non-diagonal touching of pentos when I created the first puzzles of this type a few years ago.
For the other types I think the rules in the portal are the same as in the test. Please point out if not so.
When the test is over I will post some notes and considerations about the test and selection of puzzles. |

Thanks a lot Richard. Your puzzles were lovely. Whole test was smooth for me except the Spiral City C. I forgot the loop thing, probably the reason is that I solved the puzzle as Spiral Battleships. Also I assumed that we must use all numbers from 1-32, I didn't count all segments of the city. So I experienced difficulty in the middle of the grid because of this. I erased, I repeated, but the result didn't change. But last ten minutes I remembered there was a loop : ) Then I did it. So I could be much better if I hadn't done this stupidity. Anyway, thanks a lot! |
