- Everyday a new Tapa will be available to solve. Unlike TVC, all puzzles in CTCs are to be solved online.
- CTC will follow Indian Standard Time (which is 5.5 hours ahead of GMT). Check the submission page for exact timing in your time zone
- We will be publishing week wise grid sizes in advance
- At the end of 7 weeks (on the same day that TVC 2016 ends), a winner will be declared. The winner of CTC will have a title called Classic Tapa Master.
CTC Scoring systemThe scoring system and formula are exactly same as previous years.- Submissions within 60 minutes will be considered for scoring
- 2 minutes penalty for each wrong submission
- 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
- Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
- Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
- Total points for a player is sum of puzzle points over 7 weeks.

I did after proving that the middle 3 clue had to have its right shaded, but proving that needed a fair bit of trial on its left. After that though this had very nice logic with connectivity prevented through certain areas. swaroop2011 commented at 2016-01-05 09:08:31Tough one. Not my day i guess.
I started out correctly, but kept making same mistake every time in the top. But anyways this is just getting started, hoping to catch up score on other days.
Grizix commented at 2016-01-05 09:31:44Same as Prasanna.
And I never thought I'd say that about a puzzle ^^ Para commented at 2016-01-05 15:04:48I couldn't see the path in the solve, but figured it out now. rob commented at 2016-01-05 16:03:54My best argument so far is: The only way to connect the two halves of the 33 clue locally leaves the 2 of the 24 clue stranded on the right, so regardless, we have to loop from the top of the 33 clue all the way around the top right to the bottom middle. This implies that R5C3 is shaded, among others. Since the 24 clue takes one of the 13's shaded cells, as does the central 3 clue, R7C3 can't be shaded.
rob commented at 2016-01-05 16:04:38The best bet for solving quickly still seems to be a case distinction on the central 3 (and don't mess it up... ). xevs commented at 2016-01-05 19:50:46tough...t'was bad day for me too...

Finally avoided the mistake. back to back hard ones. : ) swaroop2011 commented at 2016-01-06 02:31:42and yeah forgot to mention, there is nice uniqueness trick in top left : ) rob commented at 2016-01-07 14:15:14Besides the uniqueness, what I learnt here is that if two corners of a 113 clue are shaded, then all four must be shaded. Still not a smooth solve for me. Para commented at 2016-01-07 19:00:01@Rob: Same goes for the cells orthogonally adjacent to the clue cell around a 113. Rohan Rao commented at 2016-01-08 17:18:16Liked the flow of this puzzle. Though, took me a while to get things going. And completely missed the break-ins, ended up guessing throughout. Rohan Rao commented at 2016-01-08 17:20:13Sorry, posted the comment on wrong day :- ) The above comment was supposed to be for 7th-Jan.

But the batch of unsolvable puzzles at the start has put me into this guess early mode, and experimental solving just doesn't work for me with the applet... swaroop2011 commented at 2016-01-08 03:01:43nice easy one. I guess i did one mistake with 2-2-1 combination clue, apart from that went smooth. Para commented at 2016-01-08 09:57:08Not sure why, but I kept clicking the wrong button. Still a good time though. rajeshk commented at 2016-01-08 15:32:08Nice puzzle

Stared at it for 2 whole minutes before I saw my mistake. sayan commented at 2016-01-09 07:08:57from where you started to begin? hinowbye commented at 2016-01-09 12:43:40i started from the bottom right
Para commented at 2016-01-09 14:46:47@Sayan: Think about how the 33 interacts with the 6's next to it. Rohan Rao commented at 2016-01-09 15:27:15That was indeed fun! rajeshk commented at 2016-01-09 20:27:23Nice puzzle. once I was able to put some boxes in bottom right everything went very easy.

A nice puzzle once you figure it out though. rob commented at 2016-01-13 00:49:37Hmm, care to share a hint? I only saw the wrong way out of the bottom left fail when the puzzle became non-unique in the top left... (And then it does fail due to connectivity, but that's going quite far. ) It's nice when the required case distinction is near the start, though, because then I can just "Clear Puzzle". Prasanna16391 commented at 2016-01-13 00:51:10Its a lot of connectivity stuff, thinking that something can't come out from two separate places at the same time. The bottom 3-1-1 can also be proven to be straight or curved early on which helps. Prasanna16391 commented at 2016-01-13 00:53:40Specifically, the top left part of the bottom 3-1-1 will have to be part of the "3" of it and the top right of it can either come out upwards through the middle or through the right, meaning the bottom has to come out from the right. Does require some forward thinking but not much if you spot the right patterns. kiwijam commented at 2016-01-13 06:24:03I've done this a few times now, but still don't see much logic at the start. If you guess wrong then there's no immediate contradiction, and you can continue happily until connectivity fails later. But I suppose guessing is probably still faster than trying to find a logical track. kiwijam commented at 2016-01-13 06:29:24PS I found the top-right corner a faster place to start guessing. john_reid commented at 2016-01-13 06:29:57Yeah - it was just TOO hard. Para commented at 2016-01-13 09:32:19That was confusing. My brain really kept excluding correct options. Surprised I'm still so far at the top.
rajeshk commented at 2016-01-13 12:41:03For any guess I made, contradiction came very late and I have to redo this puzzle many times. Very nice puzzle to get your brain ticking. anderson commented at 2016-01-13 21:15:35I kept thinking I had a contradiction when guessing my way through it, and it turned out that my very first guess wasn't actually a contradiction but I thought it was. Oops!
Is there a solution that doesn't involve thinking more than two steps forward at any point? rob commented at 2016-01-14 00:56:34I'm somewhat closer to something reasonable now (trying out chess notation ): A3,B4,A5 shaded, DE6 blank. Can't go through below E2 (else D3 can't escape ). Wall between CD4 (else D2 can't escape ). There's now two options for C3: B3B4C4 shaded, in which case D3 has to escape along DEF3, or D234 shadedin which case D1 must also be shaded (say for A3 to escape ). So we also have two options for E2, and in both cases, F1 is a shaded 1.
rob commented at 2016-01-14 01:03:08...
Now we see that F3 has to be part of G4's 3, and its group can either escape up along the center, or to the bottom right (but not both ). So F3 has to escape along the right of I3. Now H4 must be blank, so G4 connects with G5's 3, hence G6 is blank. So our bottom right group needs to escape via I78 and EFG10. H8's 1 must now be H9, so we must shade H567, and finally we're ready to resolve the bottom left.

Ah well. Nice puzzle. john_reid commented at 2016-01-14 07:51:31Much nicer than yesterday's! [I could actually work this one out.]
Great puzzle - I really like the theme of only 1 clues. Rohan Rao commented at 2016-01-14 16:06:26This was really pleasant to solve after yesterday's 'colourful' one. rajeshk commented at 2016-01-14 19:59:58Very nice theme swaroop2011 commented at 2016-01-15 00:33:57Yes i also missed the bottom left flow. Did that at the end.

Tried to use uniqueness to put a line across the top from one 3 to the other. Which obviously didn't go well... gareth commented at 2016-01-15 04:28:09I love the false uniqueness-assumption temptations in this puzzle. : ) Rohan Rao commented at 2016-01-15 15:26:14Interesting puzzle to defy intuition :- ) rajeshk commented at 2016-01-15 18:05:17Uniqueness used at many places in this puzzle. swaroop2011 commented at 2016-01-15 23:03:06No uniqueness rule requried. Logic flows through nicely.

Really cool puzzle. hinowbye commented at 2016-01-18 00:55:40got stuck on the upper left corner, dunno why. : ( cool puzzle but couldnt do it logically rajeshk commented at 2016-01-18 01:05:50I have to guess many times in this puzzle to solve it completely. gareth commented at 2016-01-18 02:49:09Far too hard for me - will give up playing if there are many more that take this long since I don't have time. john_reid commented at 2016-01-18 05:30:54Yes, again, this was much too hard for me. I was ok with the top right and bottom left corners, but the diagonal from top left to bottom right was a complete mystery. I just ended up guessing and guessing and guessing which I hate to do. Maybe there was a way to use the 1-1-2 clue along with that pair of touching 1-4s to force that path in the top left? Anyway, it beat the hell out of me! achan1058 commented at 2016-01-18 06:04:11Without a way of marking edges, it is just too taxing to solve on screen. I ended up guessing quite a bit, as it is the quicker way to go forward. Prasanna16391 commented at 2016-01-18 08:48:59There is a connectivity progression there, there is no way for the top right and bottom left to connect through the 2-2s, and so they both need to go down to the bottom right separately using the 4-1 clue. If they connect directly using the 4-1 clue then the wall stops there. So top right will take the "4" and the left side will take the "1". I had to make a colour change and then realize it was a little unnecessary. That happened yesterday too. swaroop2011 commented at 2016-01-18 09:43:20Very nice puzzle. I did 2 mistakes while solving and had to undo little, could have saved 100 seconds more. But very nice logical flow using connectivity. I loved it. snehasanjeevini commented at 2016-01-18 09:47:01Can somebody please explain the top left part? I am getting splits both at 1-4, 1-4, 1-1-2 clue and the middle 1-2, 2-2, 1-2 set. Prasanna16391 commented at 2016-01-18 10:01:07Smaller sizes are coming up again tomorrow, so I'd think the time requirement would drop with that. Prasanna16391 commented at 2016-01-18 10:08:07The wall goes around the two 4-1s to the top part, and doesn't connect through the 1-1-2. R3C4 and R4C3 are the "1s" for the 4-1 clues, and R4C4 is unshaded. Try connecting it now. snehasanjeevini commented at 2016-01-18 10:39:36Yeah..got it ...thanks : ) Rohan Rao commented at 2016-01-18 12:27:03Ok, that was hard. I think I just got lucky with my guesswork. Grizix commented at 2016-01-18 15:04:36Found that one easier than yesterday, so more pleasing.
Although, it would be really better if we could mark borders, as achan wrote.
I had to guess in the extreme top left and bottom right corner, but found the connectivity problems with the 2-2s and the 1-4. Just guessed that the wall goes around the two groups of two clues.
Guessing is not only luck, it's also intuition, which comes with experience ! tamz29 commented at 2016-01-18 22:48:17woah! pretty surprised with my time - didnt have to guess much - the puzzle broke into 4 corners and its a matter of joining them.

... and YES, with 758 sec, I am in the first 20 !! ;- ) ;- ) swaroop2011 commented at 2016-01-21 00:22:33damn what the hell i was doing. Bad day for me. bskbri commented at 2016-01-21 01:40:31I worry that all tapa story will vanish in a 113 clue :/ john_reid commented at 2016-01-21 10:26:22Guessing guessing guessing guessing guessing guessing guessing guessing guessing guessing... MrLiang commented at 2016-01-21 10:51:54guessing for 113 clue more and more -_- Prasanna16391 commented at 2016-01-21 12:24:33There is a pattern here for people to know - 4-2 cannot have a shaded cell in all four corners. This helps at the top, since all the 5-1s and 3-1-1s must have all corners shaded, which forces 3 corners shaded for the 4-2. That gets some progress but I'm not sure about a solid path after that. yureklis commented at 2016-01-21 13:27:24Please... I'm expert to prepare the Tapa, and I know so many tricks. So if you cannot see the path, please don't judge "guessing". For this puzzle, I'll prepare a file that show solving steps and I'll share the link which you can see the path. Prasanna16391 commented at 2016-01-21 18:02:43I'd love to see that for the 1-3 day too. I think all authors here have experienced something like this where they put in some tricks and then solvers aren't able to find.the path. It should be taken in context, that solvers new to the tricks had to guess within time-constraints on an interface (which, no matter how great, won't replicate the markings of paper solving for some ). I've found new patterns over the course of this CTC so I don't doubt that I missed some too, and would love to learn. Prasanna16391 commented at 2016-01-21 18:31:01By 1-3 day, I mean 13th Jan. john_reid commented at 2016-01-22 08:38:23Sorry about my 'guessing' comment, I probably shouldn't have posted that. No offense intended to the constructor Serkan who I do have a lot of respect for. I was just frustrated at my own inability!

Prasanna16391 commented at 2016-01-22 19:38:08Well bigger doesn't always necessarily mean harder just like smaller doesn't mean easier, as yesterday showed. It definitely gets bigger though :P tamz29 commented at 2016-01-23 18:30:12yay

Unconscious mouse hovering, shaded some cells black which i didnt even realize : ( . prasanna16391 commented at 2016-01-23 00:48:57I continue to find new ways to mess up. Thankfully today's wasn't a huge loss, but somehow I clicked intto new tab while solving and when I came back a lot of random cells were shaded which I had to undo. Still, not as much damage I suppose. Great puzzle. A lot of basic filling with connectivity controlling the latter part of it. hinowbye commented at 2016-01-23 00:59:26somehow I put dots into some random cells without even noticing. didnt notice it until I failed twice. great -big and hard!- puzzle. TiiT commented at 2016-01-23 01:28:07Somehow I don't mess up at all. I don't like tapa but it just comes out well. :P chaotic_iak commented at 2016-01-23 02:28:41Too big that it doesn't fit on my screen. And I also forgot there's scrollbar, so I was stuck for a minute or two without realizing there's a last row that is out of view. rob commented at 2016-01-23 05:21:01The penalty for an error really scales weirdly with puzzle length. john_reid commented at 2016-01-23 09:22:43Another great puzzle!

Another great puzzle though. I don't see myself holding on to 2nd place for more than a day this time either. john_reid commented at 2016-01-25 02:40:42Lower right corner was tough for me. Excellent puzzle. I love these big ones! kiwijam commented at 2016-01-25 13:40:49Bigger are better : ) puzzlescot commented at 2016-01-25 23:14:42It would be nice to have a difficulty level visible before starting each puzzle. For the average solver, some are requiring 20+ minutes, so it's an issue if we've just put 5-10 minutes aside for a 'quick' solve. I don't think size alone is necessarily a sufficient indicator. Thanks.

My main thoughts were, "this can't possibly be a break in connectivity". Took a significant amount of time at the end checking because of this.

Unnecessary. Prasanna16391 commented at 2016-01-29 00:17:24For those wondering what I'm talking about (because it seems like others are missing it too ) - a 2-3 clue in the corner needs at least one of R1C3/R3C1 to be separate from R3C3 as the 'other' shaded block of the 2-3, and the 1-1-1-1 clue stops connectivity "around" the 2-3 because of this. I feel anyone who spots this quickly will do very well today. swaroop2011 commented at 2016-01-29 00:21:02I agree with you, after few seconds, I went for guess (not needed actually ) and it was not my lucky shot. But that guess made me realize the connectivity thing in left side. But avoided mistake today :p . Very nice puzzle again. john_reid commented at 2016-01-29 08:09:54Too hard for me and unfortunately I had to guess on this one again. I can kind of understand this idea about connectivity regarding that 2-3 clue in the corner but these things are very hard for me to spot. I haven't really been able to advance from 'local' to 'global' thinking and so I get stuck on these tricky puzzles more often than not.

Not sure it would have made much difference to my score, but I started the Feb 3rd puzzle on the correct day. I thought I'd also (just about ) finished on the correct day, but I've had the 1.15 multiplier added to my time. I assume this will be sorted out given the information that we can solve until 6.30AM LMI time (thanks Deb ), I'm just curious to know if this is expected behaviour? I.e. the 'late' penalty is applied based on finish time, not start time? Also, just for my own curiosity, are you able to check exactly how long after midnight LMI time I actually submitted the puzzle? Cheers! |

I.e. the 'late' penalty is applied based on finish time, not start time? Late Penalty applies on finish time. I think we never defined if it should be based on "start" or "finish". Let me check with Serkan and see if we should make it start time based. We will then have to recompute all days' score - there are 25 such submissions in this years CTC so far.

Also, just for my own curiosity, are you able to check exactly how long after midnight LMI time I actually submitted the puzzle? At 2016-02-04 12:00:04 AM. So 4 seconds late.

Done. Removed late penalty for all those did yesterday's puzzle today (until this time ). Late penalties will apply usual after this time. |

It should be 'start-time'. If someone starts at 11:30pm and submits at 12:01am, you can't penalize the solver for solving slow :-|

We will make this change - penalty will be applicable based on start time of the puzzle. |

Read the 3-1-1 clue as 3-1, which meant the break-in wasn't logical, guessed wrong, restarted, and checked for a good amount of time to make sure I hadn't made any other errors. The 3-1-1 shortcoming is fully my own, the puzzle is great. swaroop2011 commented at 2016-02-02 00:16:40Nice one. tamz29 commented at 2016-02-02 00:35:15Yuss!! : ) detuned commented at 2016-02-02 00:45:37Damn! The colours really weren't to my taste so I wasted a lot of time calibrating my screen. Then my mouse started squeaking which is always distracting (to be fair it had spotted some cheese ) so that after restarting a couple of times I really started to worry. Thankfully the solution then just came to me, as i from the Gods, so I didn't waste too much time! rob commented at 2016-02-02 00:53:04Well done Tom : ) achan1058 commented at 2016-02-02 01:03:16I have completely missed the opening.What a disaster. MrLiang commented at 2016-02-02 09:28:21Lucky guess in bottom-left. But, stuck in 4-1 clue (top-right ) for a short time. Rohan Rao commented at 2016-02-02 17:08:16Missed some logic midway, but got through with a lucky guess! Nice puzzle. john_reid commented at 2016-02-03 06:48:19Another excellent puzzle! It took me a while to get started - I finally got in using the 3-1-1 clue to determine the correct orientation of the 1-1-1-1. Things flowed smoothly after that. Very satisfying!

But i guess i was taking my time , so that i wont leave any cell blank and cost me penalty. It paid off. Finally did well in at least this biggest size puzzle so far. But have to wait to see other's timings to see how well i have done. Nice puzzle with connectivity and use of 1's. yureklis commented at 2016-02-03 13:28:04Sorry guys for delay, this is on me. I had to get unplanned trip to Berlin, this is a kind of vacation for me. Anyway, I did the puzzle with Toketa vol 4 theme, because I thought it would match the Toketa competition -I checked the forum Toketa posts, as I saw there are huge positive responses in there- While I was constructing the puzzle in hostel lobby : ) at the early morning, I thought is that I's done, but entering the puzzle into the LMI system we saw there wasn't unique the top left..+ yureklis commented at 2016-02-03 13:32:35corner. Then I've made several changes, but I couldn't fix the puzzle. So I had to get out the hostel and visit some places, I asked Deb, how much times do I have for fixing the puzzle, he said nearly 6 hours. But even if I had 6 hours I couldn't catch the right moment, then we had to postpone. Anyway, why I'm giving these details, because I respect solvers, and LMI. I'm so sorry all of you guys, for today's puzzle and TVC XIX date changes. Best, serkan tamz29 commented at 2016-02-03 13:49:44Two penalties. ouch : (
Thank you Serkan for doing these CTC's and TVC's for us. Have a nice trip in Berlin hinowbye commented at 2016-02-03 14:07:27Nice puzzle : ) hinowbye commented at 2016-02-03 14:07:40My favorite so far Rohan Rao commented at 2016-02-03 15:59:52Really nice puzzle. Would love to see more of these! Nola commented at 2016-02-03 17:30:55Liked this puzzle very much! gareth commented at 2016-02-03 23:58:36I'm sure noone minded waiting - it's amazing to have so many top quality puzzles to do, and all for free rob commented at 2016-02-04 00:25:38Thanks for the puzzle (and all the others ), and hope you have a great stay here in Berlin! detuned commented at 2016-02-04 02:00:31Whilst I have no problem whatsoeverwaiting for a delayed puzzle, I do think the decision to apply the 1.15 penalty less than 24 hours after the puzzle was actually published needs to be looked at! kiwijam commented at 2016-02-04 02:12:06Yes, hopefully every puzzle will be available for 24 hours before penalties are applied.
And this was a very nice puzzle, thank you Serkan! debmohanty commented at 2016-02-04 10:22:21We had announced in forum that late penalties before the puzzle was available for 24 hours will be removed. It had to be done manually.

Great puzzle with good bite ! hinowbye commented at 2016-02-05 01:35:57The feeling when you press submit before noticing you havent shaded 1 Fatal block... +120 on the score! john_reid commented at 2016-02-05 10:27:27Yes, it took a long time to see that R7C9 square. A good hidden entry point there!

I got the start very quickly but got stuck in middle for 1 and half minute, then realize that what am I missing. Then it was quick. Very awesome puzzle. kishy72 commented at 2016-02-09 00:17:219:09 on 9th February.Speaking of coincidences! .A highly difficult puzzle.Had to guess in between the solve .Solved it with pure logic later.Good one! achan1058 commented at 2016-02-09 00:22:26Missed the break-in for a while, but once I figured that out, it was relatively quick. swagatam commented at 2016-02-09 00:35:47Really a hard one, but very nice puzzle. nilz commented at 2016-02-09 00:41:07It's so frustrating when you guess, and come to a contradiction, then try the other option and find another contradiction, so you go back to the first option and find it was right all along and you just made a stupid mistake... john_reid commented at 2016-02-10 11:02:02Much too hard for me. Over 20 minutes to finish it. At least I didn't resort to guessing this time. Why can't I solve these? rob commented at 2016-02-10 13:32:24Nice one!

Really nice puzzle! achan1058 commented at 2016-02-10 00:59:04I hate that penalty. swaroop2011 commented at 2016-02-10 02:32:30I hate penalty too. Don't know why i keep doing stupid mistakes. Very nice puzzle, got it very fast with logical flow. Excellent puzzle. But put a dot at some place where it shouldn't be. damn. Could have have saved 180 seconds : ( . john_reid commented at 2016-02-10 11:35:06For me, this is the hardest one so far. Good grief this was hard. I had to guess just endlessly. CAN ANYONE HELP. I don't think I'm stupid but the entire center of this puzzle is just completely opaque to me. Is there a break in somewhere? Man, solving this was torture. Curses to this puzzle! rob commented at 2016-02-10 13:39:04Didn't see the path here, a lot of "it just feels sort of right if things connect this way", thankfully mostly correct. rob commented at 2016-02-10 13:45:25john_reid: There's a lot you can do around the edges. And then there's a central break-in which I missed: That 6 next to the 22 shares shaded cells with the 24 above, the 7 below, but must have a gap next to the 22, so it goes around the other side. From this point, things flow quite well. yureklis commented at 2016-02-10 14:17:15I've showed nearly all steps, I hope that works for you john_reid

Then it was easy flow. bskbri commented at 2016-02-11 01:36:16113's are back : ) MrLiang commented at 2016-02-11 10:19:39113 trick me again -_-" prasanna16391 commented at 2016-02-11 10:24:13Would have been faster on this if I'd started from the right, where I think the connectivity starts getting forced. Starting from the left gives you markings but nothing to really grab onto.

I hope Serkan's hand is better!
Recently I had an operation, in these days the time is not by my side, it flows very slowly, and I'm perceiving so much pain than I'd already have, I'm living a delusion : ). Also I've figured how hard to able to write : ). I have so much pain, but I hope that in next 10 days it will be better for me.
Thanks for asking |

I think i am missing some start here. will have to try again. prasanna16391 commented at 2016-02-13 00:21:05The start - the 1-1-1-1 in R7C4 forces the 1-1-2 below it to have its '2' around the 1-1-1-1-1 and so the 3-3 below the 1-1-2 can only have one of its '1's. This means R10R11C3 are shaded and their counterparts for the 3-3 clue, and I think it flows well from here. rob commented at 2016-02-13 00:32:29Hah, damn, I made that deduction with that other 1111 next to the 12, but failed to see it near the 33. Weird. rajeshk commented at 2016-02-13 11:54:40Thanks Prasanna for giving the logical break. I guessed to solve this one. However after reading your comment, I could solve it fully logically : ) masonjason commented at 2016-02-13 19:13:57I thought the interaction of the left-hand pair of (1, 1, 1, 1 )s via the (2, 3 ) was beautiful john_reid commented at 2016-02-14 01:49:32Well I was able to solve this with no guessing but unfortunately someone stopped by when I was in the middle of it and I ended up chatting for 45 minutes with them before I got back to the puzzle! It was a great puzzle though and I'm proud that I was able to work out that 1-1-1-1 and 1-1-2 interaction that Prasanna described and didn't have to resort to any guessing. Very satisfying!

The solution has been corrected. That is the reason your submission was accepted. I'm working on getting your (and Ivan's and some other players' ) timing correct. |

CTC Scoring systemThe scoring system and formula are exactly same as previous years.- Submissions within 60 minutes will be considered for scoring
- 2 minutes penalty for each wrong submission
- 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
- Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
- Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
- Total points for a player is sum of puzzle points over 7 weeks.
Details in the pdf file Download | View
Just curious -- when there are a lot of people who did not finish the puzzle (as with today's), do they get factored into the calculation for MED? |

For scoring purpose, only players with CoTI <= 1 hour is considered. All DNFs are ignored.
For example, if you go to 14th Feb's in the score page, you should see a line at the top :
Results for 2016-02-14's puzzle / Num Players : 200 / Top 10% : 20 / Top 10% AVE : 102.1950 / PuPo : 10.1091 / MED : 275.5600
All 5 DNFs are ignored. All 3 players with CoTi > 3600 are ignored too.

I know what you mean -- when I'm not well, it feels like the days last forever, and I just can't wait for the day I'm all better.
Hope that day is coming for you soon.

I re-solved it later with some very narrow connectivity logic, which was excellent and a lot of fun. But I just don't think that this was something most people would be able to see with a timer running, and with the big size its more of a lottery for someone who just intuitively solves for the middle being empty. . brecher92 commented at 2016-02-17 02:39:14I still don't see the logic with the 1-1-3 on the left side. I'm looking at a few other people's solves and see that this was handled early on, but I don't see how. achan1058 commented at 2016-02-17 02:52:56I do not understand this puzzle. The amount of guesses I have made is insane. achan1058 commented at 2016-02-17 02:57:55By the way, how do you view other people's solve? detuned commented at 2016-02-17 03:50:30absolutely brutal! brecher92 commented at 2016-02-17 03:51:37achan, it's on the standings page -- click on "Others' solves" Para commented at 2016-02-17 04:31:45Well, that was awful. swaroop2011 commented at 2016-02-17 06:49:41very hard.
swaroop2011 commented at 2016-02-17 06:50:16half of the puzzle i could solve it logically. But later had to guess couple of times which didn't went my way. anderson commented at 2016-02-17 10:24:49I guessed the 1-1-3 on the left side and got lucky because that guess propagated through the whole puzzle. Looking at it again, I'm having a lot of trouble completing it logically (i.e. not looking more than 2 steps ahead ). MrLiang commented at 2016-02-17 11:19:53Ahh!! brain block. It's look like "Puzzle Marathon" for me. : ( tamz29 commented at 2016-02-17 15:47:36Should've guessed earlier :/ rob commented at 2016-02-17 17:18:02I only figured out that left area towards the end, with some not-quite-rigorous solving before (though the middle area being empty was necessary due to uniqueness at some point ). But it's possible to start there. The core restriction there is that the bottom right cell of the 113 can't be isolated, else it breaks the single 4 together with the 24 and the 33 below. Then you can deduce that the top left cell of the 113 has to escape upwards past the 14, and the top left corner can be resolved. gareth commented at 2016-02-18 00:16:34Far too hard for a daily puzzle - I had to give up since I couldn't spend long enough on it, and come back the next day. If a puzzle is extremely hard without warning then it's unreasonable to expect people to magically have enough time set aside at the moment they discover this. It also takes away the fun of it, and means those who don't have other commitments have a definite advantage. ; )

I could not submit my solution (18th Feb) when I finished solving it (about 20 minutes before deadline). I tried again then some minutes later again but could submit only after a half hour.
Deb, sorry for disturbing again, could you check if I had the same problem as Nilz? Thank you! Fixed.
Sorry about the delayed response. |

But I get message this is incorrect. I lost about 10 minutes looking for mistake, not seeing any mistake sent the same solution and... it was correct. Is it possible? marred commented at 2016-02-22 00:33:30Ok, nevermind, I didn't click "Send solution" after making amendments and I was still thinking that even after amendments I'm still wrong. debmohanty commented at 2016-02-22 00:51:10An incorrect solution was recorded. We have fixed the same. See forum post for details. swaroop2011 commented at 2016-02-22 04:42:15I kept making mistakes. Had to restart 5 times. I dunno why i was repeating same mistake. Bad day. So one more to go. kiwijam commented at 2016-02-22 08:27:37Another great puzzle. It's sad to say goodbye soon : )
Many thanks to Serkan for this series. (I think you were the only author? ) hinowbye commented at 2016-02-23 00:31:33Today's the last puzzle?!? dang...This was fun!

What a pity... :-(
Thanks very much to all the organizers and, expecially, Serkan: it was a great contest (despite my mediocre results, but I can't expect better :-)
Looking for next TVC to have more tapa puzzles! |

Country : United States | EMJ posted @ 2016-02-25 7:55 AM Thanks so much to Serkan and all for the great puzzles and great contest. I especially liked the extended number of weeks. And the system works so well. I hope there will be another contest next year.
If there is, I have one suggestion that might not be too hard to implement. In the "Other's Solves" section, would it be possible to add a "Pause" button in addition to the stop button? After pressing the stop button, the start button clears the grid and starts the solve over. I would greatly enjoy the ability to pause on a solve to try to figure out what the next step should be and then continue from that point.
Another wish (which might be more difficult to implement) involves "reviewing" a puzzle. I sometimes clear previously solved puzzles and rework them. I would like to be able to confirm that my re-solve is correct, especially for the larger puzzles.
Thanks again, and I hope you are feeling much better soon, Serkan! |

Some statistics about CTC 2016
![](/2016/CTC/stats/st03.png)
Who would have predicted in 2012 that I would be one of the most consistent ones in a future edition? :P I still remember the drastic ups and downs from that year. Its sad that that one mistake came because of a double click around a 1-1 corner clue, would have been nice to have perfect accuracy like deu : ) |
