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.

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)
