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

No I made same way, all undivided cells have one digit like TVC IX puzzles.

@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.

For Shortest Segment Tapa: Just a small clarification as I used this in my puzzle. If there's a number on the outside, does that imply that row/column isn't empty?

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)

I forgot to comment on this after finishing as it had slipped my mind after all the puzzling. When printing the Tapa Guard, Braille Tapa and Anglers puzzle didn't fit completely on the page for me. Was I the only one having this problem or did others have this happen?

I had the same issue that Para described on all of the pages he mentioned.

I also seem to have issues with submitting correct answers and with submitting them before the penalty time runs out, but I doubt there's any help for me there...

I am not sure how to edit my previous post, but I also noticed that the second Shortest Segment puzzle had the bottom row of outside digits missing on my printout as well. That would've certainly helped to notice during the test...

I have doubt regarding the "Combination Tapa". In the given example if one replaces clue 2,4 with 7, it gives the valid solution.

Please do let me know if I am missing something in instructions.

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.

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. :)
