Location: India | Sorry,this is a bit ridiculous,in my opinion.Having so many possibilities for a clue may only increase confusion.Its hard to figure out possibilities from the large mappings during the test.I believe it should be as simple as possible. |

Location: The Netherlands | Maybe there should be a small clarification to the ir-iregular Tapa rules. Currently it reads that each shape counts as as many cells it contains. But that's not exactly correct as it could be interpretted that a 3 cell area which touch the Tapa clue with 1 cell is counted as 3 cells, even though it's only meant to be counted as 1 cell.
It's supposed to mean each cell in a shape counts towards a tapa clue if it's touching the clue.
On a side note. Can anyone explain how to approach the Full Tapa example? I don't see a way to get started. |

Location: The Netherlands | How exactly does the answer key work for Fractional cells? If you look at row 4 or row 7 for example,it can get a bit confusing.
For row 7 is it
1,2,4 (count all squares that are touching as 1)
1,2,3 (the bottom of the fractional cell only)
1,2,1,1 (the top of the fractional cells only)
1,2,2.75 (all cells touching, but fractional cells counted as fractions like in the clues)
For row 4 it's even so that the fractioned cell has two seperate pathways running off the same cell.

Location: India | If R6C6 is used by a vertical word,it can be One ,zero,two,six or four.One,two,six fail as it leaves a white space of 2 cells in the top-right corner.Four or zero leave R6C3-4 white,so they fail too.that leaves r6C6 with a horizontal word,which is atleast 4 long to satisfy the black block in the last row.A 4-letter word would leave a V-shaped 5 which leaves a white space in R5 that cant be filled.So only three can use the 6th row.This completes 6 and the entire right half.R1C6 must be black.Done!

Can this question be answered, please? It seems kinda important for the test to know how the answer key works for this particular type. If it's irrelevant because no fractional cells will be in the answer rows and columns that would also help to know.

Location: United States | Para: The test's puzzle did not mark rows or columns with a divided cell, so it's fine. (edit: ok'd to say this by Deb in an email)
Thanks for the great test. As my post in this topic suggested and as my comment on motris's blog made more explicit, I was really worried about the set of variations here, but the test turned out to be the load of fun a TVC usually is. Happy with how I did, but taking it so early means it's a long wait to see how I compare with others...

You're welcome.
Well done on the test. Its my turn to have a series of messed up performances now. Hopefully that ends in TVC XII but I guess this puts me back quite a bit. :\ Ah well. |

Location: Germany | I'm still uncertain about the Ir-irregular Tapa. Especially as the unofficial test puzzle by Para seems to follow different rules!?
Is the following correct: I blacken some areas. Each area has to be either completely black or completely white. When checking the clues and the 2x2-condition the blackened areas are treated as separate black squares.

Yes, thats right. A 2x1 area for example shall be counted as two cells for clue-counting purposes and a L-shaped Trimino that gets shaded means that 3 cells out of a 2x2 region are shaded. Hope that clears it up. |

Location: India | Congratulations again to MellowMelon for winning TVC XI by a huge margin.
xevs and deu take 2nd and 3rd position respectively.
EKBM also played really well, but had a mistake in one puzzle.
Out of 126 players, 109 players got non-zero scores.

Location: India | With Serkan not around, I'll put some remarks like he does every time.
There were lot of discomfort among players when the IB was released, must be because of so many new types and some unfamiliar rules. MellowMelon was one of the first players to participate, he had a great performance, but he also posted in forum immediately that the puzzles were nice. Thanks and congratulations for yet another superb performance.
- The puzzle solved by least competitors was Power of Tapa. It was solved by 20 competitors.
- The puzzle solved by most competitors was Fractional Tapa. It was solved by 96 competitors.
- The puzzle with the highest rating was Visionary Tapa (9.28) and the puzzle with the lowest rating was Mad Max Tapa (Top) (6.16).
- The puzzle submitted with the highest accuracy was Dissected Tapa (100%), 64 competitors), lowest was Mad Max Tapa (Bottom) (48.89%, 22/45 competitors)
Here is the link to Cumulative results table - http://logicmastersindia.com/TVC/2012.asp
See you all in the next and final round.

Location: United States | So as I said a few days ago, the test did turn out to be really great. One suggestion I have that would scare everyone less is to not complicate the IB more than it needs to be. Specifically, say up front that the test's Meiosis Tapa would have only even numbers and no multi-number clues. I guess it's possible the IB was released before the puzzle was ready and/or finalized, but that variation as it was in the IB was just plain unwieldy. It's intimidating as hell to have a clue like 1 2 that can function as 1 2, 1 1 1, 1 1, or 1 5 (this possibility eliminates a lot of connectivity logic the clue might have otherwise). The test puzzle itself was great though.
Still not a fan of Mad Max. One good thing about logic puzzles like these is that as hard as solving them can be, checking them is usually easy and straightforward. But for a type like Mad Max, it's almost impossible to be totally sure you have the right answer; computationally, verifying a solution is as hard as solving the puzzle. I think the low success rate on that second puzzle is both not surprising and not a good thing. |

Location: The Netherlands | I wasn't really enthusiastic at first when I saw the IB, but found enough interesting variants to fill my 75+ minutes after taking a closer look to all the puzzles.
Unfortunately I spent a lot of time on the meiosis tapa, running into contradictions at the same place all the time. I thought to have understand the rules properly, but obviously it's not. So I am very much interested in the solution. If someone can post it here in the forum I would be happy.
Because of the time spent on the meiosis, I just missed the Visionary tapa by a minute.  It was a wonderful puzzle, with a brilliant start. Thanks Serkan! |

Hi,
Even I have confused myself during the test, but this is a simple puzzle, after the test it took around 8 minutes for me.
I hope the solution is correct.

Ravi

Location: The Netherlands | Thanks!
My problem was the 6 in the middle. If you divide 6 by 2 yo get 3, not 3/3. So I assumed I did something wrong but didn't know what.
As far as I can see, the IB doesn't contain an example where an even digit gives a two-clue digit after dividing.
Did anyone else have problems with this or is it just me who can't read?  |

Hi,
Para has explained by taking 2 2 as an example in this thread, probably you might have missed it.
