The homepage link to the contest seems to have vanished. For a moment, I was worried it was already over!

Funny. Anyway, here's the link, just in case people haven't noted it - http://logicmastersindia.com/2016/CTC/submit.asp#

nice puzzle

Is there no puzzle today? There's one listed in the schedule above, but there's no entry for today's date when I view the calendar on the competition page.

Sorry about that. We will be posting a puzzle, it will take some time, may be an hour from now.

Since today's puzzle was available at around 6:30 AM, players can solve it until tomorrow 6:30 AM without late penalty. (All timings as per LMI server's time)

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 was too slow spotting the 4-1 clue getting resolved.

---

k3isim commented at 2016-02-01 00:33:32
Satisfied by my solution, but... waiting half a minute for server response with running timer - a bit annoying...

---

kishy72 commented at 2016-02-01 01:06:17
My mind interpreted the 3 and 3 clue on the bottom left as 3-3 clue in a single cell and I was getting a stranded island wondering what's wrong for ~15 seconds.Arghhh!

---

tamz29 commented at 2016-02-01 06:51:10
Wow. 1 minute was added to my time because of "waiting for server response" ... >:(

---

debmohanty commented at 2016-02-01 08:49:02
k3isim,tamz29,thesubro - Adjusted the timing.

---

k3isim commented at 2016-02-01 20:53:38
Thanks! :)

Right, I will have to do it manually, after the specified time is over. It is not automated.

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.

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.

Ouch. 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 00:16:40
Nice one.

tamz29 commented at 2016-02-02 00:35:15
Yuss!! :)

detuned commented at 2016-02-02 00:45:37
Damn! 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 00:53:04
Well done Tom :)

achan1058 commented at 2016-02-02 01:03:16
I have completely missed the opening.What a disaster.

---

MrLiang commented at 2016-02-02 09:28:21
Lucky guess in bottom-left. But, stuck in 4-1 clue (top-right) for a short time.

---

Rohan Rao commented at 2016-02-02 17:08:16
Missed some logic midway, but got through with a lucky guess! Nice puzzle.

---

john_reid commented at 2016-02-03 06:48:19
Another 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!

swaroop2011 commented at 2016-02-03 07:24:27
wow that was really nice. Easy flow. 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 13:28:04
Sorry 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 13:32:35
corner. 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 13:49:44
Two penalties. ouch :( Thank you Serkan for doing these CTC's and TVC's for us. Have a nice trip in Berlin

Really nice puzzle. Would love to see more of these!

Liked this puzzle very much!

gareth commented at 2016-02-03 23:58:36
I'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 00:25:38
Thanks for the puzzle (and all the others), and hope you have a great stay here in Berlin!

---

detuned commented at 2016-02-04 02:00:31
Whilst 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 02:12:06
Yes, 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 10:22:21
We had announced in forum that late penalties before the puzzle was available for 24 hours will be removed. It had to be done manually.

---

6th Feb's puzzle is delayed. Will post here when it is available.

Mouse issues again, but pretty minor this time.

swaroop2011 commented at 2016-02-04 02:22:57
After big one yesterday, this was a relief puzzle. Pretty easy, but nice one as usual.

---

MrLiang commented at 2016-02-04 10:03:39
wrong guess in 1-1-1-1 again :(

---

That's sad to know. Wish you a speedy recovery, Serkan!

Will the CTC still be 50 puzzles or just end on the normal date?

Completely missed the bottom right break-in. Nice puzzle

---

swaroop2011 commented at 2016-02-05 00:18:33
yeah same here. Took way more than required time.

---

kishy72 commented at 2016-02-05 00:30:19
Realizing R7C9 cannot be shaded is vital here in this puzzle.Solving it multiple times later made me realize this. Hopeless :( . Great puzzle with good bite !

---

hinowbye commented at 2016-02-05 01:35:57
The feeling when you press submit before noticing you havent shaded 1 Fatal block... +120 on the score!

---

john_reid commented at 2016-02-05 10:27:27
Yes, it took a long time to see that R7C9 square. A good hidden entry point there!

---

I hope Serkan's hand is better!
