Location: Turkey | A clarification of Lonely Tapa. The instruction says "each orthogonally connected are of empty cells can contain at most one clue cell." So if it says "at most" it means there might be some empty cell blocks that don't connect any clue cells, however in the example all empty cell blocks connect to exactly one clue. So, please check the new example, because there might appear some empty cell or blocks that doesn't have any connection with clue cells.

Location: United States | For Tapa 1-n, is it required that the numbers of cells in each row/column must be in the range 1-n (as the name seems to suggest)? Or can there be rows/columns with 0 shaded cells? |

Sounds like Serkan's Tapa and Variations book is just what you're looking for: http://www.gmpuzzles.com/store/classic-and-variations-series
Otherwise the TVC archives provide plenty of practice material: http://logicmastersindia.com/TVC/ |

Why are all answers marked as wrong? (Or just all 7 people who have submitted so far did not get any correct answers, but I doubt that!) We had not (yet) entered the solution keys in the score page. Have done that now. Please check score page again. |

All nice puzzles, no complaints. Okay, maybe Chain Tapa should be named Cyclic Tapa (#105, p40), but otherwise no problem. All good puzzles; memorable ones are Arrow Tapa, the second Anglers Tapa, and Tapa Pentopool (which I typoed because I thought the last grid was 10x10, not 11x11). |

Location: Germany | Thanks Fatih and Serkan, that was a lovely set of puzzles.
I struggled quite a bit with the Chain Tapa, and breezed through the Power of Tapa, but other than that things felt pretty even.
Now I look forward to the next one! |

I didn't really have a good run. There were a lot of errors on my side. I had to restart a number of puzzles.
The grey cells in the Chain Sudoku were too light for me. I couldn't really tell the difference between white and grey very well on my print. Also a minor nitpick, it wasn't technically the right variant as that was a Cyclic Tapa. |

All of the puzzles I tried were very fun, thanks Serkan! I especially enjoyed the second Black Hole tapa, and the Arrows tapa. |

I didn't realize the gray cell brightness, mostly I'm using nearly same gray tones in a booklet, but next time I'll be much more careful about this. You are right about Chain Tapa, one of the competitors mentioned same issue, I know. Several years ago when Cihan offered these variants I said they are same, but from his side, it was not. I think the Cyclic Tapa variant already contains the Chain Tapa idea naturally, so Chain Tapa is not a different variant. After designing the competition puzzle for TVC XIX, I'm much more sure now. So I'm going to remove the Chain Tapa variant from the TVC Variant List. |

Honestly, this was my very first online contest and it was pretty fun. Puzzles were creatively designed(at least I can say this about the puzzles I accomplished to solve). I really enjoyed this idea of competing online on a particular type of puzzle and I am looking forward for the next one. Nicely done! Thank you for your effort! |

I'd remove Cyclic Tapa instead; cyclic implies it must make a cycle, while chain doesn't, so it's Cyclic Tapa that is contained in Chain Tapa, not the other way around.
I'd suggest to even change the name or something. For me, "chain" sounds like you solve a grid fully, then you move to the next grid and solve it fully, then the next, and so on; later grids don't influence earlier ones. But that's a minor nitpick; it's maybe just me. |

Having shaded and unshaded squares in this puzzles was not the best decision. I would rather use some easily recognizable pictures, for example squares, triangles, circles, stars to mark the chain clues. Anyway, thanks for the contest, it was pretty fun.

It make sense, I'll change the example and instruction of the puzzle as you suggested |
