Yes, you are absolutely right, IIII should be IV.

Thank you very much!

For training I took a Knapp Daneben Tapa from TVC I. It made me absolutely crazy. I've spent more then two hours on it and couldn't solve. And what is most mysterious - I see I had points for this puzzle in the contest.

:) Sorry Andrey, there was an error in this puzzle:) I wrote some into the German Forum about it: http://forum.logic-masters.de/showthread.php?tid=543&page=2

You can try Knapp D. in the OAPC 8: http://oapc.wpc2009.org/archive.php?id=48

Thank you Serkan. You soothed me. I was afraid if I became so stupid since last year :)

But now I think wrong puzzles are very useful for training. I've found a lot of logical ways to start solving this puzzle. May be I could use some of them in the contest.

Truly, in roman numbers "4" could be wrote also IIII (I know it very well 'couse I'm from Rome..., also Akuma is from Italy but not from Rome... :-)

For examples see: http://www.google.it/images?hl=it&pq=wikipedia+roman+number&xhr=t&q...


So it's interesting to know if we can use IIII=4 in the contest...


There's a very little mistake in "Tapa row" solution: r5c6 should be black.

Thanks very much for those wonderful contests,

best regards,
Gabriele

:) Yes, as i remember, we had a grandfather clock, and its four was IIII. But in the contest, Four is IV. And i will add a remark about it.



I've checked the example, and i couldnt any mistake. Actually i didnt understand why should be blackened R5C6.

'couse.... I don't know!!!! Sorry, I was sure the clue in r6c6 was a "1-1"

hello yureklis, i came across one of your puzzles here http://www.logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000... and i couldn't put V shape that drove me mad. can you please point out the place of it ? i wrote there but i think i can get reply months later so i am writing here. thanks in advance and congrats for all your efforts.

How points are distributed for the Matchmaker Tapa? There is 5 puzzles, and I can see points for 6 puzzles.

Nikola

As mentioned in IB, there will be 6 grids. But 1 of them will be unused.
Serkan has decided to award points even for the UNUSED grid. So if you know which one is unused, you can enter 0,0 for that grid and get points.

If you've solved all 5 used grids correctly, you directly get points for UNUSED.
But you have not solved all 5 correctly, but you know the one which is UNUSED, you should enter 0,0 to get points for that.

Hope it is clear.

Puzzle booklet uploaded. It has 9 pages (including a cover page)

Please note a rule about "Arrows Tapa"
Each clue "?" should be replaced by any digit from 0 to 3.

Is there a way to get to the downloads of TVC I-IV ?

You can find them here:

Players can view their score after the contest.
Note : this time player's own score only will be displayed.

It's a pleasure :))

Thank you Serkan for yet another wonderful competition. And thanks to the LMI team for running the website where so many fun competitions take place.

I would not normally do this, but may I have points for Tapamino (Easy)? My mistake came in listing a clue number as part of my solution; I assure you I did not think a domino went on top of that clue number! :)

You are welcome Ziti. I have manually checked all wrong answers which entered so far, and some of them accepted as correct solution. You got the points from this puzzle. Please check the result table.

Thank you for participation.

One day I'll finish an online competition without making an entry key mistake. (I know, it's not a very inspiring life goal, but it should be achievable, right?)

Thanks for the puzzles, Serkan.

I hope that you can reach the online goal :) I am not good at focusing. I am jealous of somebody who manage perfectly. In the WPC's i was following competitors, and most of them weren't aware of anything around themselves during the test. They see only paper. In the past i was the same, but now i am so careless :) In the OAPC Series, each test contained 40 +1 puzzles. And some of them were completely solved and all puzzles entered correctly by some solvers, Thomas, Ulrich . Sometimes i think about it, and this is impossible, but some player could make it. Amazing! You held a test in LMI, you can understand what i am talking, when i enter the solutions of all puzzles for any Tapa contest, i entered a few wrong solutions :) Also i checked one more time, but i didnt notice. Although i wasn't competing, i had 80 minutes to enter all solutions, there wasn't any pressure on me, i kept on entering wrong solutions :)

I read an interview with Will Shortz somewhere. He said that it is important to solve puzzles fast, but there is one more thing, it is attention. If anyone wants to become a good solver both fast solving and attention is required. After reading this sentence, i thought, yes he is absolutely right. Because i had chance to follow some good solvers in WPC. My example is Ulrich. Everyone knows about his solving skills, but his one more skill is attention. He doesn't make mistakes easily. In the final of WPC Antalya he did a mistake, i was really surprised. But i thought that everyone sometimes could make mistake. He was penaltied one minute, and he got back paper, he solved again the puzzle, he gave the solution, but referee penaltied one more time. When i saw this i realized that ooo absolutely we did a mistake! And i was totaly right, there was a mistake but not Ulrich's, it was ours.

Shortly, attention is really important . I think this is very short final sentence :)

I don't like when the answer system is too difficult and/or it give the solvers an extra exercise, for instance counting cells.
Because in this case the typing of the answers is relatively much time, and easier to make mistakes, this is can influence the result.
I'm happy that on the TVC the answer system is really simple and uniform.

Thanks for making these past few tapa contests, with lots of creative puzzles. It was great fun doing them!

I also made a typo on answer entry for Hungarian Tapa. Like Ziti above, I wouldn't normally ask for this, but could I have points for it? I do realize it's not as clear a mistake, but it is obvious that I wasn't paying attention when I typed in two 3's in the same row (which was the only mistake), and I only had about 20 seconds left. I am asking this for self-esteem reasons, of course, as the typo reduced my potential score by about 1/4. :)

Serkan
Thanks for another verygood (but addictive. my wife starts to complain.) contest

another addition to the typing errors. on tapa quad I typed the row below the row B shown (without glasses....) could you forgive me?
