Logic Masters India announces Tapa Variations Contest XXII

Dates: 25 - 30 June 2021 (Extended till 1st July)

Length: 75 + 5 minutes

IB and Submission Link : https://logicmastersindia.com/live/?contest=TVCXXII

For Transparent Tapa, would a T-tetromino satisfy a 4-clue? I don't see any restrictions on it here, but think I recall a variant where there had to be a path, and wanted confirmation.

That would work. No restrictions on it indeed.

Answer Key for Puzzle 4 - Tapa Pentopool

There are 8 rows/columns to be entered.

Please enter answer keys for two letters together in one box as indicated.
A and B should be entered in the box for AB
C and D should be entered in the box for CD
E and F should be entered in the box for EF
G and H should be entered in the box for GH

Example: If answer key for A is 12 and answer key for B is 45 Then participants need to enter 1245 in the box for AB

Important points

1. There shall be no instant grading in this test.
2. There shall be no online solving interface (like penpa) provided for this test.
3. If the length of shaded cells in any answer key is more than 9, you need to enter the complete value, not just the unit digit.
4. There shall be 11 pages in the Puzzle Booklet, including a points table on Page 1.
5. Participants can submit answers any number of times. The last submission shall be considered for scoring.
6. There shall be no separate notification on submitting answers. There will be no claim bonus button either. So, if you think you have submitted all answers correctly, the bonus will be calculated based on the last submission time.
7. The timer will show the full 80 minutes. But there shall be penalties if answers are submitted after 75 minutes.

Puzzle booklet

The password protected puzzle booklet is available for download and has 11 pages - including a point table on Page 1.
The test starts at 8:00 AM IST on 25 June.

Does Neanderthal (44) have two solutions?

Does Neanderthal (44) have two solutions?

I don't think so. You can share what two solutions you got here and someone can probably see if both are correct. Remember + cannot take the value of 1, it has to be 2 or more.

Great balanced difficulty. Enjoyed all the puzzles. Unfortunately broke one puzzle at the end otherwise went smooth.
Glad to have solved both the high pointers.
Thanks to the Authors, Testers, and LMI.
Looking forward to the next TVC.

Neanderthal (44) - A, C, and D are 142, 2212, and 142, respectively, in both the solutions that I got. B can be 2121 or 2111. (Sorry, I was not able to reply to the previous post).

Hi,

I entered the answers in the wrong format. I entered the length of both shaded and unshaded cells (considering clue cells as unshaded).
I know the rules explicitly stated to enter only the lenghts of shaded cells but is it possible to consider this.
It's okay if it is not considered but is there some way for me to know if my answers were at least correct?

snehasanjeevini: I think I can tell which part you are thinking about but B cannot be 2121, that will break the clue on R10C5.

kheti: I have no control over answer key appeals but the Solutions Booklet will probably be shared after the contest is over.

Cheers,
Murat

Your answers are all correct. We will consider your submissions (and any other participants who have submitted in this format).

Tapa Rundweg: Does the "no black 2x2" rule apply? It's not mentioned in the rules.

Tapa Rundweg: Does the "no black 2x2" rule apply? It's not mentioned in the rules.

Yes, it applies.

Thanks a lot Rakesh. Glad to hear that.

Thanks Swaroop, I can confirm it does apply. Cells inside the loop count as shaded cells forming the Tapa, which has no 2x2 shaded cells as a base rule. I get the uncertainty though, I probably should have added a sentence like "Shaded cells obey Tapa restrictions." or just specifically added the no 2x2 rule again to be safer. Apologies for the confusion.

I do not see claim bonus button, is it mistake on my side?

I do not see claim bonus button, is it mistake on my side?

Its mentioned in "Important points" earlier on this thread that there shall be no "claim bonus" button.
(However, there is a line in the IB about claim bonus which may have led to the confusion.)

Bonus shall be calculated automatically if all submissions are correct.

I was a bit worried about this TVC after the last one, and was potentially going to skip it and solve the puzzles on my own time later. I found myself with some unexpected time tonight and I'm glad I decided to give this a shot- very fun set! I don't have any favorite puzzles because they were all excellent, which is a great problem to have!

Contest Extension

TVC XXII is extended by 24 hours and shall be open till Thursday 11:59 PM IST (1st July) - based on requests.
(Participants must start the test before 11:59 PM IST on 1st July.)

Hi Rakesh,

Wanted to check if I will also be able to see my score after the correction in the Scores page for this contest or will it be adjusted somewhere else?

update: already got it, my mistake.. :D

Is it possible that Power of Tapa has 2 solutions? Mine was not accepted, but I doublechecked and it seems fine. Anyway, I'll wait until adrenaline level is down and check again :D

I submitted the answer of a puzzle twice. The first was wrong and I got a 10% penalty for the correct one. I think this might be bug in the code. And is there a way to make protest in the new contest format?

Fixed for all players.

The Solutions Booklet is now available.

Thanks to the 144 participants! Congratulations to the 10 finishers!

Congratulations to the Top 3: Endo Ken, Freddie Hand and Jeffrey Bardon.

Not surprisingly, the highest pointer had the least correct submissions. Notably, Mad Max Tapa 2 had only 60% correct answers.

Thanks to the authors for a more approachable TVC this time!

Hi,

I believe answers for this contest were also going to be accepted if the format was different than the one mentioned, specifically if the length of both shaded and unshaded cells were entered.

Where might one find the scores adjusted to reflect this?
