I lost a lot of time on today's puzzle as it was stuck for a while on "waiting for server response". So I decided to click again after almost a minute and registered the time of my second click. That sucked.

I kept making the wrong deductions today for some reason.

---

prasanna16391 commented at 2016-01-25 00:13:04
I resolved it now, and progress starting from the right is a bit tougher than progress starting from the left, but just enough that if you start there you can continue working it out. .This was mainly what slowed me down I suppose. Another great puzzle though. I don't see myself holding on to 2nd place for more than a day this time either.

Lower right corner was tough for me. Excellent puzzle. I love these big ones!

kiwijam commented at 2016-01-25 13:40:49
Bigger are better :)

puzzlescot commented at 2016-01-25 23:14:42
It 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.

I missed the trick a little again by waiting on pause-spots too much. This has been a really enjoyable week of large but not difficult puzzles.

Circle the 8s!

swaroop2011 commented at 2016-01-26 02:39:00
uff finally not that bad day. I missed the other 2 big puzzles. But no mistake on this one. Very nice puzzles. I wish there are more big puzzles coming in next week.

rajeshk commented at 2016-01-26 09:20:38
Nice big puzzles. Yes, looking forward for big puzzles next week :)

Yeah, a lot of 8. But, 8 and 2-4 trick me -_-

prasanna16391 commented at 2016-01-27 00:49:12
A lot of fun. Did a colour change for the start just to be careful, but it is definitely visible without that.

---

gareth commented at 2016-01-27 01:35:12
Would be a little easier if 'undo' worked properly! :)

---

achan1058 commented at 2016-01-27 02:05:08
Took me a while to find the break in, but other than that, it is fun.

---

swaroop2011 commented at 2016-01-27 02:19:25
yes took a while to get started, almost spent 2 min to put few cells and then it was quick run. Very nice puzzle :)

---

puzzlescot commented at 2016-01-27 08:31:04
1/2 hour of trial and error before deducing the break-in, then done in 5.

---

MrLiang commented at 2016-01-27 09:50:00
bottom left clue nearly trick me. It's zigzag. -_-

Loved it! I was fortunate enough to get a quick start on this one.

prasanna16391 commented at 2016-01-28 00:08:03
For some reason this had some strange connectivity which my head just couldn't wrap around. 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. Cool puzzle.

---

kishy72 commented at 2016-01-28 00:33:25
I submitted at 2:21 precisely.The server registered by time as 2:27 .It showed "waiting for server response" while the timer continued to run??!

Tricky finish for me with the right hand side. Took a while to work out the 6, 3-3 and pair of 2 clues on the right wall.

---

swaroop2011 commented at 2016-01-28 23:39:41
Very nice puzzle. Made silly mistake although just at the end, or else it would have been a nice finish.

prasanna16391 commented at 2016-01-29 00:05:29
Should have spotted the continuity break in top left, went for a guess instead. Unnecessary.

---

Prasanna16391 commented at 2016-01-29 00:17:24
For 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 00:21:02
I 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 08:09:54
Too 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.

---

MrLiang commented at 2016-01-29 09:54:27
1-1-1-1 wrong guess slow my time record. -_-

---

achan1058 commented at 2016-01-29 20:05:26
I hate messing up minor details. Forgot to colour a square on the bottom left.

---

rob commented at 2016-01-29 23:06:38
I didn't spot the connectivity thing, but my wrong guess near the 33 did lead me to quickly discover it, and then it went smoothly from there.

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

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.

prasanna16391 commented at 2016-02-02 00:04:03
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.

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!

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

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.
