Does the each digit outside the grid show the ONLY clue(outside or skyscraper)? Mustn't the each digit match BOTH clues? |

Country : France | Hi Kota,
Each clue must fulfill at least one of the rules. It may be that it fullfills both, but there is no obligation. Anyway, you don't need to worry about that anymore since this puzzle has been removed in the last version of the IB.  |

Country : India | Clarification on Odd Even FrameOutside/Skyscraper is out, but the same rule applies for Odd Even Frame as well. That is, each clue must fulfill at least one of the sums. It may fulfill both, but there is no obligation.
For example, if 4 is the clue outside, the first 3 digits could be 1,3,4 in any order.
This has been clarified earlier.

I am not able to completely understand rules of "Linked Classics". Can someone please explain it.
There are 2 grids. The solution of the 2 grids are same, except that some rows have changed their positions.
If you look at solution of the example, R3 of left grid is same as R5 of right grid. Similarly R6 of left grid is same as R4 of right grid.
See image below.
Is it clear now?

Country : Estonia | TiiT posted @ 2013-02-09 4:17 PM It was brilliant test until I got to Odd Even Big Small. I mean, why are you not describing the puzzle in a booklet? I still don't know, how to solve it. Do you except us to find out which symbol is which? Or is there other classification for these symbols? That is different puzzle as in booklet! You should have said in instructions_booklet that you must figure the symbols out by yourselves or describe the other symbols. I think that the one puzzle ruined the beautiful test - everything else was nice. |

Country : Finland | UllaE posted @ 2013-02-09 9:52 PM I agree with Tiit that I would have liked to practice the same type of Odd Even Big Small before the competition. As such, at least I didn't have the capability to figure out how to go around solving it. IMHO, the whole point of publishing the instruction booklets in good time ahead of the competition is to give time to solvers to practice the correct types and their solving techniques, so that the time used for solving during the competition actually measures the solving capabilities and not that how fast can one read and understand the rules.
Otherwise, I also enjoyed the competition a lot. Thank you! |

Country : United States | The surprise in Odd Even Big Small evokes memories of the 2004 USPC Corral puzzle, where the instructions were subtly different, which allowed for the surprise of a hex grid rather than the standard rectangular grid. In retrospect, nothing said that you would be able to know right away which symbol corresponds to which property.
I personally liked the surprise, giving a fresh take on a well-known variant. |

Yes, that was unexpected surprise but if you read the instructions carefully, there is nothing mysterious. Rules are the same in IB and PB. I agree that we should think little more than usually.
I always remember 1st WSC in Lucca when I was angry because of "undefined" rules. There was one product killer sudoku with central cell divided in four cages. After that I realized that sudoku is a wonderful mind game. My understanding of sudoku today is not limited to simply fill the numbers like a machine.
Many excellent puzzles. Thanks Deb!

I was unable to solve the puzzles in logical steps. No easy or medium puzzles. No puzzles for non-experienced players. |

The 2004 USPC Corral used the same instructions before and after the test. That the word "cell" and not "square" was used meant the constructor had flexibility to be creative. The OEBS puzzle here follows the same mold, and as a tester I was not thrown for a second with what to do.
Surprise puzzles are always an interest consideration for competitions. The Sudoku Cup has consistently had one, with no instructions shown to competitors in advance. It takes great care to do this right. And some solvers, during the stress of competition, will be too focused on thinking one way to be able to see anything else. |
