Got distracted for a long time from the true opening near the bottom left :) Flow was nice after that.

So difficult...

Thanks much for the timer extension!

Pretty much had to use uniqueness on this one, just wasn't spotting the necessary logic. Went back and resolved and it was pretty well constructed. I see Serkan used the 22-22-23 pattern again ;)

---

gareth commented at 2013-09-07 00:13:30
Nice solving theme, although trying to solve it quickly I only spotted it by accident as I repeatedly got it wrong. :)

---

macherlakumar commented at 2013-09-07 12:55:00
Certainly a hard one right from start to end. Serkan has put the same trick as Sep 4 puzzle. R4C3,R5C4 and R6C2 clues. Puzzle is completely packed with deductions only. Honestly solved this by intuition only.

---

carljohan commented at 2013-09-08 11:50:31
Too hard for me too :(

---

so with bigger size grids this time,
i guess with big PuPo, the rankings gonna be affected by large amounts if we do mistakes :)
Hope to do good. :)

I'm one of the first victims :P Hopefully, I make it up with the other big ones.

Adjacent clues... still my nemesis.

---

kiwijam commented at 2013-09-09 08:18:14
A minor setback, but I'm sure you'll survive (unless Serkan suddenly changes the rest of the puzzles). I enjoy adjacent clues, they're better for us logical plodders, whereas separated clues are better for the intuitive solvers. What do others think?

---

prasanna16391 commented at 2013-09-09 12:18:58
I'm not sure what to classify mysellf as. I'd say I use a bit of both, but mainly, compared to last year, I'm solving a little slower and going for consistency. Within that constraint, I think I'm faster when there's more of connectivity type logic, and a bit slower at clue-influenced logic. Many times I just forget to mark the basic patterns until its a bit late.

yureklis commented at 2013-09-09 14:18:03
I'll make some changes :)

What a stupid error! Great thematic puzzle.

---

rob commented at 2013-09-11 01:39:27
Well... took quite a while to realise that two neighbouring 2s aren't neighbouring 22s.

---

swaroop2011 commented at 2013-09-11 06:11:07
Ahha, I guess because of symmetric clues arrenged symmetrically i was able to do fast as most of the places no need to think again :)

---

swaroop2011 commented at 2013-09-11 06:11:43
But yes an awesome and beautiful puzzle to begin the bigger grids :)

---

kiwijam commented at 2013-09-11 16:09:06
Serrkan, I was just kidding ;)

---

yureklis commented at 2013-09-11 16:12:43
:) I know. I made these puzzles nearly one week ago

---

debmohanty commented at 2013-09-11 16:27:16
I will have the solution ready in a paper, and see if I can type it in '113' seconds

---

chaotic_iak commented at 2013-09-11 18:34:30
@deb: Actually it's possible; you only need to shade the black cells right. If you don't just see the paper (but also thinking for some trivial steps so no time wasted looking on the paper), 113 sounds likely. :P

---

figonometry commented at 2013-09-11 23:08:00
I like the big grids, except when it takes forever to find a stupid error.

prasanna16391 commented at 2013-09-13 00:09:31
Got a slight pause for connectivity in the middle, not as easy as the other two big ones I think. I could be proved wrong though :)

---

yureklis commented at 2013-09-13 00:14:56
You are right, this one is harder than last two big puzzles. If I remember correctly you need to black just one cell for connecting two groups in the end. Probably some solvers will miss this.

---

gpagano commented at 2013-09-13 03:51:16
I probably am one of the solvers who missed that last square :P. Thanks for all the puzzles so far Serkan.

Very good puzzle. Cleared many of my concepts of Tapa puzzle

Couldn't find the logical path during my solve for the left side, but got it afterwards. Tricky finish.

---

feels good to be at first place even though for some time ;) :)

prasanna16391 commented at 2013-09-16 00:55:02
Used just a little uniqueness in some places there. Its pretty hard logically. Some nice little patterns that aren't normally used. 2,1-2 reastricted the 1-1-1-1 to just one possibility and that gives a fair start.

---

yureklis commented at 2013-09-16 01:03:02
Yes, you are right about the starting point. I used minesweeper logic, it worked well. I tried to preserve whole design from uniqueness effect, but it could be put final position of clue 6 with using uniqueness. However this is not big deal for the puzzle. I think this is a hardrock Tapa :).

---

These smaller grids seems to be much more exciting than the bigger size grid ones ;)

Very nice logic here, I made a complete and utter mess of things. Kept thinking I had it wrong and then actually going the wrong way and then confusing myself entirely :|

---

yureklis commented at 2013-09-18 00:17:36
This one is based on connectivity. How do you connect upper left blocks to bottom left blocks?

---

prasanna16391 commented at 2013-09-18 01:12:31
I think the puzzle can be solved a lot by using the top left 4s area. I did do that the first time but made a few misclicks resulting in lot of clearing and problems.

---

prasanna16391 commented at 2013-09-18 01:12:51
Eek, top right I mean. I'm confused at everything today apparently :P

---

deu commented at 2013-09-18 06:10:10
Extremely hard for me! Connectivity logic is always my weakness.

---

easonrevant commented at 2013-09-18 08:00:02
I started with a lucky guess!! i should be using deductive logic -_-

---

swaroop2011 commented at 2013-09-19 02:06:01
excellent puzzle :)

---

MellowMelon commented at 2013-09-19 09:56:56
The email conversations I've had with Serkan suggests he considers it a personal victory whenever he gets me to make a mistake. I think he won two victories with this puzzle...

---

yureklis commented at 2013-09-19 12:21:38
Actually this is not my intention. You are so fast in the Tapa. So I'm thinking Palmer is so fast, how should I make puzzle so that all solvers has a chance for being winner of the day, or winner of the whole contest. So my intention, my goal is that balance. I want the contest to be fun and I want that every solver has this feeling that they can be the winner of a day. Nothing to do with my personal satisfaction :) I'm such an old puzzlemaker for this stuff :)

macherlakumar commented at 2013-09-19 00:45:25
The puzzle is a very brilliant construction, has many heavy deductions. The complete puzzle is based on connecting the middle two blocks with upper block and in the end with lower right block. The puzzle itself needs to be solved considering the connectivity of middle two blocks with upper block 10+

---

rob commented at 2013-09-19 01:25:30
Definitely missed the proper solving path here, quite a bit of uniqueness deductions with a bit of guessing at the end (lower left).

---

swaroop2011 commented at 2013-09-19 02:05:15
awesome one :) Too many deductions to be made great construction 10++++

Phew. Ended my free-fall. Not great, but I think I did ok today. Nice puzzle, as always.

gareth commented at 2013-09-20 01:33:38
Missed a single square in the centre. Bah.

---

swaroop2011 commented at 2013-09-20 17:56:53
unknowingly i put some dot at some place which in turn made it no solution to reach until later i realized why the hell that dot is der. :(

I think thats the end of any chance I had at 3rd. I just hope I stay in the top 10 :P

---

macherlakumar commented at 2013-09-21 00:12:36
I am not sure why I read the center as 221 but ended up with a valid solution even for that clue, after penatly found that its 211 and luckliy the fix was small

---

MellowMelon commented at 2013-09-21 00:39:59
Oh, that 1-4 up top is more constrained than it looked. That explains why I found this one so hard; I went around the middle in the wrong direction...

---

ksun48 commented at 2013-09-21 04:22:37
Okay, I think this has got to be the hardest puzzle so far.

---

Grizix commented at 2013-09-21 08:19:14
Wow, really hard, as I went through a lot of trial & error, I would really appreciate a walkthrough for this one.

---

rajeshk commented at 2013-09-21 08:24:09
I thought that I will not use trail & error in CTC but this puzzle made me to use that.

---

kiwijam commented at 2013-09-21 17:35:27
Walkthrough start: The cell at the bottom-left corner of the centre 112 cannot be filled, because it cannot escape in any direction. This means the other 3 corners of the 112 are all filled.

---

For everyone's information, we had to redo CTC computations for dates 11th to 23rd after we disqualified a player. ToPo for all players at the top have increased by around 1 point because of that.

Will all Tapas be available for download after the contest?

No.

That was harder than it seemed in first place. 2 errors for me ...

We have a mild shake-up at the top of the table. 5 more Tapas to go.
