Must say, those are some awesome smug-looking fish.

For those of you who don't already know, I created one of the Anglers Tapa type on my blog here - http://prasannaseshadri.wordpress.com/2012/02/04/puzzle-no-35-36-ta...

Note : Slight difference in the rules on mine and the IB - in mine, the fish aren't part of Tapa wall.

You can use that for practice, since some of you may already have done so.

Looking forward to more tapa fever :p

I hope the authors don't mind - I've created a 'no solutions' instruction booklet for those who want to do the examples without any spoilers, attached.

Hi,
I have a doubt in Magnetic Tapa.
I think the polarity order in Column 1 (marked in a rectangle) should be -, + instead of +, - as given in IB.
Please let me know if I am wrong somewhere.

Regards,
Ravi

@anurag: Could it be that your "total false" tapa has multiple solutions? I can replace the "24"-clue at the right border by "1" or by "111" and find solutions in both cases.

edit: I also find multiple solutions for your braille tapa. Is there some mistake on my side?

It says there will be 2 grids given in the instructions for tapa and pata. For the distiller you will get 5 grids. The overlapped grid and 4 empty grids to put your puzzles in.

You just had to make the rules so my Shortest Segment Tapa was incorrect. I let the puzzle run a lot on "there has to be a minimal segment" rule. Will make something new. Luckily I hadn't posted it yet.

Serkan's new version is a bit complicated and i do not like it much(only for a timed test).Also,unless you would like to indicate that a row is not empty,there is no point in using '1's as a clue.I would prefer to know that atleast one segment of that length has to be there.

Yes. If there is a outside clue (sure it will be) it means that there must appear some blackened blocks.

Why would you want to confuse the solver with a clue if the row was empty.


Well it could be possible for a row to only contain 1 and 2 segment pieces because of clues or other parts of the wall and by putting a 3 there you could force the whole row to remain empty. Which wouldn't have to be the case if that 3 wasn't there. But it doesn't apply here, just showing how it could be helpful if the option was there.

That's the real panache: You share everything you know, then you win the tournament, and then you say: "I proved that I'm the best !", (and then perhaps everyone hate you)

Was Braille Tapa perhaps inspired by my and Alan Fetters' Mystery Hunt puzzle this year, or was it a complete coincidence that it appeared here? I'm honored if so, amused if not. I found the tiny alphabet subset (including a "letter" that is not actually a valid Braille letter) interesting. It's definitely more manageable for the solver, though undoubtedly limiting for the constructor.

As Serkan has mentioned in the IB (last page), Braille Tapa was certainly inspired from your Mystery Hunt puzzle, or more likely from your blog post.

Second round of TVC 2012 has ended, thanks to all participants. The top three are as follows:

2. Kota Morinishi (JAP)
3. Bram de Laat (NED)

Congratulations to Palmer, he showed great performance with completing all puzzles in 62 minutes. He was the only competitor to solve all 17 puzzles. He seems to have fixed his disadvantage in the first contest.

Some statistics:

- The puzzle solved by least competitors was Tapa Distiller. It was solved by 10 competitors.
- The puzzle solved by most competitors was Tapa and Pata - Tapa. It was solved by 129 competitors.
- The puzzle with the highest rating was Tapa Difference (8.55) and the puzzle with the lowest rating was Tapa Guard (6.7).
- The puzzle submitted with the highest accuracy was Anglers Tapa (%97.26, 71/73 competitors), lowest was Tapa Guard (%69.09, 38/55 competitors)

See you next round!

Ah, thank you, I didn't realize that there were credits at the bottom of the instruction page. I wasn't fishing for a credit (actually, I was more afraid that I had forgotten there was a Braille Tapa puzzle on the contests last year and had inadvertently stolen the idea from someone else) but I certainly appreciate one...it impressed my wife, at least. :)
