I am having a little problem in understanding the answer key for Tapa Rotator. I am unable to understand how we get A and B for the rotated grid as shown in the IB. I am getting a different answer as shown in the attached image.

Both grids have their own A and B.
Your marking of A and B in the rotated grid is incorrect.

May be the rows should be marked as A, B, C, D to avoid any confusion.

I have a question regarding the rules of Double Tapa. Is the solution in the example unique? Why can't we add one more cell to the inside wall (the one to the right of the 4-clue) ?

Also, very nice set of variations!

Thanks for noticing, the example not have unique solution. As you noticed there is a problem with clue 4. Because there is no reason to leave the cell next to 4 empty, it may be a grey cell.

I have question about Tapa Connection. "Connect the identical letters with snakelike lines going vertically or horizontally" means that lines cannot touching itself? Because line C is touching itself...

No, each one can touch itself. Snakelike means the line cannot have any branches.

Hi all,

I have a question for Tapa Connection: all the black cells should belong to one of the snakelike lines?

Thanks,

    For Tapa w/borders, in the IB it says that clues outside the border will be invalid, but the 3 on the bottom row is. Should it be a different number, or should the instructions say 'not necessarily valid'? Thanks! looks like a lot of fun!

    Yes, outside clues will be invalid, because it is needed to consider only final grid, clues are not important out of the final grid.

    ATTENTION
    Word Tapa: There is an unclear phrase in the instructions. Each word should intersect or overlap with another one, but the instruction doesn't state this clearly. E.g. if there are two words as ONE and TWO, they can be TWONE but they cannot be TWOONE or ONETWO.

    All submissions will be checked manually. You can solve the puzzle as you like, the solutions will be accepted if it is correct with or without intersecting every word.

    Great puzzles, I still haven't finished all of them, but I'll be sure to do so.

    I realised, though, that I have posted my answers to the Tapa with Borders puzzles in the fields for the Tapa Possible puzzles. It would be very much appreciated if you could amend this error on my part.
    I guess the error-checking system isn't of much use when the answers to all puzzles have the same format :)

    I believe there is another bad sentence on the WORD TAPA puzzle.
    "Different words can intersect only if they share a letter" says the booklet. but in the example VARIATION and CONTEST share TWO letters (ON).
    should the instruction say "if they share at least a letter"?

    Question on Tapa Star from someone who has done the test: does the count of cells between the two stars include the two stars themselves? I interpreted as if the stars in a row were in column 1 and column 6, then 4 would be entered for that row (columns 2,3,4,5 are between them). If that's not what you meant, can credit still be given?

    serkan,
    very nice set of puzzles.

    for tapa rotator i combined row A and row B answers in the first row and second rotator puzzle's answer in the next row, amounting to both puzzles tagged as incorrect. can this be considered?

    Serkan for really nice set of puzzles and LMI for hosting
    this event. Tapa is a really nice puzzle type and its different
    variants increased a lot. Just by looking at normal tapa and its
    many variants I hope you will invent some other new puzzle types
    in the future...

    David McNeill.


    I agree with you. I didnt make puzzles in different difficulties, i have a reason for this. In the last year we didnt use any bonus points, and in this year we dont want to break TVC rules. I had to make most of puzzles not easy due to lack of bonus points. Because we dont want to have a lot of participants who solved all puzzles. But i am afraid of not being good. So we decided to make much more puzzles than TVC V so that offering much more easy puzzles to all participants in next contests. We think that is better.

    Best,

    Serkan

    good set of puzzles as usual. a bit confused about tapa word do not understand why the second puzzle is wrong, perhaps did not understand the rule about overlapping of words.
    Pity because costed me penalty points to amend a typo from the solution which was wrong anyway

    Stefano, you got the points from second word tapa. In the forum we announced that we check manually word puzzles solutions because of some ambiguous instruction . So your solution is correct, and you got the points.

    First contest of 2011 Tapa Series is over, many thanks to all participants and LMI.

    The top three competitors are:

    1- Thomas Snyder (USA) - 15/15 - 49:01
    2- Andrey Bogdanov (Russia) - 15/15 - 71:27
    3- Florian Kirch (Germany) - 15/15 - 72:32

    Results can be viewed: http://logicmastersindia.com/TVC/V/score.asp

    Congratulations to Thomas for first victory of Tapa 2011 Series. He solved all puzzles in amazing total times. I think in this year Tapa Series will be more challening for everyone.

    * TVC V has 15 puzzles, and next contests will have much more puzzles than this.

    *
    - The puzzle solved by least competitors was 10B - Tapa Possible.
    - The puzzle solved by most competitors was 2 - Tapa Filler.
    - The puzzle with the highest rating was 10B - Tapa Possible and the puzzle with the lowest rating was 2- Tapa Filler.

    * Last year we mostly prefered to get B/W answering format. All competitors had to enter marked row/column contents. But this was hard for all of us, so we changed the general answer format. This one is shorter and easier than the old one. But as a contest designer I have doubts in this answer format, about the puzzles being solved almost completely by competitors. So I chose some rows which need being more careful, like Tapa Filler second row, or 2nd Tapa rotator first row. Please remember this for next contests.

    * We will follow same pattern like previous year. So, your first contest results will be transferred to the general table multiplied by a constant. I think the table will be available after TVC VI.

    * Same like last year contests' total points will rise, of course penalty points too.

    * Please remember in this year best 3 results out of 4 will be considered. So, it is not important to have one bad performance.

    * TVC VI instruction will be published on 14 February.

    * One more thing, if you have variation ideas please share us.

    All the best,

    Serkan Yurekli

    I had an email exchange with him and here is what he had to say regarding his timings.

    >>
    So what I do on a test is submit puzzles when I finish a sheet and discard it to the floor. Sometimes I'll do this independently when there are two puzzles on a side, but certainly a full side when that's done as after I check the entry I won't look back at that page until everything is done.

    You can see I solved from front to back (generally). I made a mistake in putting stars into the Tapa Star the first time through (there is a single cell that the Tapa can grow into that is necessary to solve it and I didn't consider this the first time), so I printed a new grid to put the wall in and restart the labeling. During this time I jumped and did the Words. So the gap to finish Tapa Star is not perfectly accurate. More like 3 minutes just to put the stars on it from the time data you see. Rotator was straightforward. Borders involved being lucky with 6x6 blocks a little bit (I excluded two edges in each case). Double Tapa was easy for me as I had learned the 221 corner break-in from some Crocopuzzle practice, and then I saw how to go along the right edge with the other wall. It was a very fun puzzle. Tapa Connection involved a few trials around the A and D, but eventually once I got one good path I could get the rest quickly. The Tapa Possible were really fun and at least the second solved from considering how the white clue areas would block you from getting to some of the grays twice. Figuring out to leave corners blank for the 3/3 gave a good nucleation site for the rest to grow out. Tapa is a puzzle type where some logic and also some intuition from a guess can work together really well. I got lucky more often than not this time around. We'll see how TVC VI goes.

    Good start of the new season of tapa. Congrats to Thomas for an excellent time and also congrats to other toppers!

    I didn't forget to submit my last puzzle. Somehow, but I still don't know how, I imagined in double tapa that two tapas cannot form 2x2 square. After the competition, when I realized where I'm wrong, I solved the puzzle in two minutes. Very stupid mistake.

    Serkan, thanks for the password!

    Next time, could I play while sitting on the floor of Thomas' room?

    Thank you Serkan, this was a really good competition.
    The TAPA STAR and TAPAPOSSIBLE are very good new tapa variations. However, the WORD TAPA won't be my favourite tapa variation :)
